iv Introduction The assessment, monitoring, and protection of our nation’s diminishing wetlands are current priorities of the United States Environmental Protection Agency (USEPA). The assessment of wetlands may be particularly challenging due to the wide variety of transitional states or habitat conditions that occur in wetlands (Costanza et al. 1991). Since 2001 we have been collaborating with the State of Utah to collect aquatic invertebrates from Utah’s wetlands to describe some of the natural variability that is likely to occur in wetland invertebrate assemblages. Utah’s broad geographical diversity in elevation, precipitation, and vegetation communities sets the stage for a wide variety of wetland types to occur. Preliminary classification schemes of late have generally followed the Hydrogeomorphic (HGM) approach (Brinson 1993, Stevenson and Hauer 2002). The hydrogeomorphic approach attempts to characterize wetlands based on broadly based functions and comparisons to expected functions for a wetland within the same class. Classes are defined with respect to such attributes as surface water storage, water chemistry, and vegetation communities. In Utah, wetlands have been characterized or classified with respect to their environmental setting, hydrologic regime, and salinity. Environmental settings were defined by reference state and ecoregion. Water regimes have been defined by the duration of time surface water is present. Ephemeral wetlands are described as having surface water present for brief periods (three months or less per year) in some years. During drought years they may not receive any surface water. Seasonal wetlands are described as having surface water present for longer periods (three to six months per year) in most years. Wetlands with longer surface water duration have been separated into two categories: semi-permanent and permanent. Semi-permanent wetlands are described as having surface water that is common to persistent in all years for six to twelve months per year. Permanent wetlands have surface water that is continuously present in all years. The overall goal of this study was the development of an assessment method to describe wetland health or status with respect to reference sites based on aquatic

1 invertebrates. The aim of this report is to describe the natural variation in wetland aquatic invertebrate assemblages that occurs with respect to several classification schemes and to describe the correspondence that we observed between aquatic macroinvertebrate assemblages and the wetland classes that have been defined to date. To date there has been little correspondence reported between wetland invertebrate assemblages and environmental characteristics (Wissinger et al. 1991, Battle and Golladay 2001, Batzer et al. 2004) or land use activities (Tangen et al. 2003). The reason for this is not entirely known but may be related to 1) the generality in habitat preferences exhibited by many wetland invertebrates (Batzer et al. 2004), 2) the mobility of many wetland invertebrates (Bilton et al. 2001, Batzer et al. 2004), and 3) the patchy distribution of vertebrate predators, such as salamanders (Wissinger et al. 1999).

Study and reporting description Our study of the aquatic invertebrates of wetlands in Utah began in 2001. In 2001 we collected invertebrates from 38 wetlands in northern Utah, principally around the Great Salt Lake and west desert area. This earlier work focused on identifying sampling locations and evaluating different sampling procedures for collecting and processing aquatic invertebrate samples. The results of this work are available in Vinson (2002). The work presented in this report describes the sampling and collections we made in 2002 and 2003 during which an effort was made to sample wetlands throughout Utah as well as those near the Great Salt Lake and to describe the correspondence that we found between aquatic invertebrate assemblages and environmental and land-use based classification schemes.

Study area In 2002 and 2003 our field technician accompanied the UT-DNR survey team to ensure uniformity of data with the purpose of creating unified temporal snapshots of the wetlands. In 2002 the study area was expanded beyond the GSL ecosystem and the Great Basin Ecoregion to include high elevation wetlands within the Rocky Mountain

2 Ecoregion. In 2003 the survey area was expanded again to include more Rocky Mountain Ecoregion sites and some in the Colorado Plateau Ecoregion. All geographical coordinates were collected using a Garmin E-trex GPS unit and documented along with other site data. The majority of the sites in the Great Basin Ecoregion can be described as ephemeral or seasonally wet playas or ponds and spring-fed wetland systems. The majority of the Rocky Mountain Ecoregion sites can be described as seasonally wet potholes and wetland ponds. The majority of the Colorado Plateau Ecoregion sites can be described as ephemeral or seasonally wet tinajas and plunge pools.

Methods Locations and physical habitat The majority of sampling locations were selected by the Utah Division of Wildlife Resources Wetland Coordinator. The specific sampling locations within each wetland were determined using GPS units. Elevation was determined using 7.5 minute topographic maps. Water and air temperatures were determined at the time of sampling. The conductance of the water was determined using an Oakton TDS Testr 40 meter and the pH was determined using an Oakton pH Testr 2. Water depths, substrates, and vegetation communities were described in general terms. Water and samples were collected and analyzed at the Utah State University Soil Laboratory. These data are reported in Keate (2005). A field map of each site was drawn noting location of water, dominant vegetation, major landform features, man-made structures, and the general location of where the samples were collected.

Photo points Wetland features were photographed using a Samsung Digimax 240 digital camera and downloaded after every sampling trip.

3 Aquatic invertebrates Field methods –In wetlands, aquatic macroinvertebrates occur in three habitats: benthic, planktonic, and nektonic. Each of these habitats typically supports different invertebrate taxa and each can be a challenge to sample. Benthic substrates typically vary from fine silt and organic debris that can quickly fill sampling devices to rooted vegetation or hard clay that limits one’s ability to collect samples. Using a sampling net with 500-micron mesh openings and agitating the sample through the water while in the net allows much of this sediment to be washed out. Common invertebrates located in this habitat zone include members of the Trichoptera (caddisfly larvae), Odonata (damsel and dragonfly larvae), Coleoptera (larval beetles), and Diptera (midges/ Chironomidae) Orders. Planktonic habitats occupy the area between the upper water surface and the substrate, i.e., the water column. This open water habitat is generally easy to sample using hand-held samplers or zooplankton samplers unless thick emergent vegetation is present. This area is not typically rich in macroinvertebrates and the invertebrates that are found here are generally good swimmers and can be difficult to collect. In areas where emergent vegetation is present, these habitats are difficult to sample because this vegetation hinders the movement of sampling devices. Common planktonic invertebrates can include members of Odonata (dragonfly nymphs), Heteroptera (water boatmen and back swimmers), and Chaoboridae (phantom midges). Nektonic habitat is the area at the water surface. This habitat is generally easy to sample and can contain many planktonic wetland invertebrates as well as true nektonic dwellers such as Heteroptera (water striders), Collembola (semi-aquatic invertebrates), and Coleoptera (beetles). A common issue and challenge in collecting aquatic invertebrates from wetlands is to collect a representative sample from each of these habitat types without collecting so much material that the laboratory processing of these samples is cost prohibitive. It is quite easy at many wetland sites to collect samples in 2-5 minutes that require 10-20 hours of laboratory time to process, i.e., to remove the invertebrates from the organic and inorganic debris. A compromise must be reached such that the majority of the invertebrate taxa at each site are collected but the sample processing time is not so

4 long that adequate time is not left to visit all the sample sites. At this time there is no national, regional, or statewide protocol for collecting wetland invertebrates. In 2001 we compared samples collected qualitatively to those collected more quantitatively. The results of this work was that there were few differences in the assemblages collected using these two methods, but the time required to process the quantitative samples was substantially more, >10 hours compared to less then 2 hours for qualitative samples (Vinson 2002). In 2002 and 2003 all invertebrates were collected using qualitative methods. The objective of our invertebrate collections was to collect as many different invertebrates as possible within a reasonable amount of time. In this study we limited collection time to about 30 minutes. Samples were collected with a rectangular kicknet / dipnet (457 x 229 mm) with a 500-micron mesh net and placed in a tray with clear, fresh water. The invertebrates were then hand picked from vegetation and woody debris, preserved in 95% ethyl alcohol, and brought to the lab for identification. Collecting a large number of invertebrates increases the chance of finding a representative of each different species. It is very difficult to tell similar species from each other with the naked eye. In 2001 we collected a minimum of 250 invertebrates. The number of organisms collected in 2002 and 2003 was increased to a minimum of 500 organisms. Laboratory methods — The general procedures for processing invertebrate samples are similar to those recommended by the United States Geological Survey (Cuffney et al. 1993) and are described in greater detail and rationalized in Vinson and Hawkins (1996). All invertebrates in the qualitative samples are rinsed through a 500- micron sieve, which washes away any organisms that are too small to identify. This material is then placed into a Petri dish and all organisms are removed under a dissecting microscope at 10-30 power. During the sorting process the organisms are separated into taxonomic Order. All of the organisms removed during the sorting process are then identified to Family, Genus, and Species, if possible. The data are then entered into a computer and checked. All identified organisms from each sample are placed together in a vial with 70% ethanol, given a catalog number, and retained in our laboratory collection. All aquatic invertebrate data are processed at our laboratory.

Site classification Wetland sites were classified into several major environmental classes. These included ecoregion, slope or depression wetlands, water regime, salinity, and reference and non-reference condition status. Data for all classification attributes was not available for all sites where aquatic invertebrate samples were collected, so not all sites were placed into each category. The number of sites sampled within each class is shown in Table 1. Ecoregions (Olmernik 1986): 1. Great Basin, 74 sites 2. Colorado Plateau, 5 sites 3. Wasatch and Unita Mountains, 40 sites Salinity classes: 1. Very low salinity < .15 dS 2. Low salinity .15 dS< 7.5 dS 3. Moderate salinity >7.5 and <22.5 dS 4. High salinity / hypersaline > 22.5 dS Water regime classes: 1. Ephemeral – surface water is present in some years for brief periods (<3 months) 2. Seasonal – surface water is present in most years for 3-6 months 3. Semi permanent – surface water is common to persistent in most years for 6- 12 months 4. Permanent – surface water is continuously present in all years. Depression or slope wetlands 1. Depressional wetlands are topographic depressions with closed contours. Water sources are precipitation, runoff and/or groundwater. Water flow vectors are toward the center of the depression. The dominant hydrodynamics are vertical. They may or may not have inlets and outlets.

6 2. Depression / slope wetlands are depressional wetlands found within slope wetlands which occur at points of surface changes, breaks in topographic slope or at stratigraphic changes. Groundwater and runoff are the primary water sources. Water flow is unidirectional (down slope/ gradient). Water may discharge to a stream, lake or depression. Wetland sub-classes Wetland subclasses were assigned based on principal components factor analysis of reference sites. The classification was most strongly influenced by water salinity and water regime. Water salinity was determined by electrical conductance of the water and if no surface water present, soil salinity was used. 1. Hypersaline (EC > 22.5 dS) seasonal (Subclass 13) or semi-permanent (Subclass 23) depressions – These reference standard hypersaline depressions most often occur in close proximity to the Great Salt Lake. They are dominated by salt grass (Distichlis stricta), which on average comprised 84% of the total vegetation cover and 26% of the relative cover. The total relative cover was very low, averaging 27%. Annual samphire (Salicornia europaea) and Utah samphire (Salicornia utahensis) were the second most dominant vegetation species with an average cover of 3%. Other species that commonly occurred at these sites included Triglochin maritima (maritime arrowgrass), Cordylanthus maritimus (alkali birdsbeak), Scirpus maritimus (alkali bulrush), Suaeda depressa (broom seepweed) Triglochin palustris (marsh arrowgrass) and Sporobolus airoides (alkali saccaton) with average cover of 1%. Vegetation species richness was four at reference standard sites. The remaining cover was made up of unvegetated mineral flats and shallow open water. Typical invasive species that occurred included Hordeum jubatum (foxtail barley), Phragmites australis (common reed) and Kochia scoparia (summer cypress). Disturbance tended to increase both the species richness and the percent vegetation cover. Percent cover increased with the addition of artificial water sources. The EC of the water averaged 49.5 dS (range 24.1 – 100dS). The average pH was 7.6 (range 7.00-8.30).

7 Soil pH averaged 7.7 and the EC of the soil averaged 131.8 dS. Soil and water chemistry data from non-reference standard sites was limited, but indicated elevated zinc and lead in the soils and elevated lead levels in the water. There were no hypersaline permanent depressions in our data set. (33) 2. Moderately saline (7.5 – 22.5 dS) seasonal depressions (Subclass 12) – Vegetation characteristics of these depressional wetlands were similar to hypersaline seasonal and semi-permanent depressions. Differences included a higher percentage of vegetation cover, averaging 36% and higher species richness, averaging seven species. All of these sites had artificial water sources, which tended to keep the water less saline (average EC 10.98 dS) and to increase the cover, especially of salt grass. The pH of the water was high (8.5-9.8). In addition to the species that occur in the hypersaline depressions, these less saline depressions contained Puccinellia nuttalliana (Nuttall’s alkaligrass), Scirpus acutus (hardstem bulrush) and S. americanus (Olney’s threesquare). All sites were located above 4217 ft elevation. Black- necked stilts are commonly seen at these sites. 3. Moderately saline (7.5 – 22.5 dS) semi-permanent (Subclass 22) and permanent depressions (Subclass 32) – As in other saline depressions, Distichlis stricta (desert salt grass) was the dominant species. The total vegetation cover averaged 69% and often included Salicornia utahensis (Utah samphire), Scirpus americanus (Olney’s threesquare), Juncus arcticus (wiregrass) or Eleocharis palustris (common spikerush), Triglochin spp (arrowgrass), Sporobolus airoides (alkali saccaton) and Cordylanthus maritimus(alkali birdsbeak). When these sites are disturbed, Phragmites australis (common reed) invades. In reference standard sites, the average species richness was 4, while in disturbed sites it increased to as high as 11 species. The average EC of the water was around 15 dS and the pH was about 8.04. Soil EC varied considerably. Soil pH averaged 7.84. Lead was sometimes high in the water and soil in areas of waterfowl hunting. All sites

8 were located above 4217 ft elevation. Many of these depressions received their water from nearby springs. Snowy egrets were common at these sites and occasionally Wilson’s phalaropes were seen feeding in the open shallow water. 4. Freshwater (0.15 dS>EC< 7.5 dS) seasonal (Subclass 11), semi permanent (Subclass 21) and permanent depressions (Subclass 31) – In the Great Basin Ecoregion, there were no natural, unimpacted sites in these subclasses. All natural sites were impacted to some degree and other sites were created or impounded management areas. In seasonal freshwater depressions, Distichlis stricta (desert salt grass) was the dominant vegetative species. Average cover was 22%. Scirpus americanus (Olney’s threesquare) and or Scirpus maritimus (alkali bulrush), averaged 11% cover and occurred at all reference standard sites. Other species occurring at these sites included Salicornia europaea (annual samphire) in all reference sites. At 50% of the sites Sarcobatus vermiculatus (greasewood) and or Allenrolfea occidentalis (iodine bush), occasionally Puccinellia nuttalliana (Nuttall’s alkaligrass) and Poa palustris (fowl bluegrass) were found. Total vegetative cover averaged 48% and average species richness was six. Water EC was around 6.3 dS. The average pH was around 8.6. Soil pH averaged 8.6. Soil EC was extremely variable. High lead levels occurred in areas of waterfowl hunting. At a site near Kay’s Creek, an exotic snail, New Zealand mud snail (Potamopyrgus antipodarum) was collected. At semi-permanent and permanent freshwater depressions, Eleocharis palustris (common spikerush), Scirpus spp., usually Scirpus americanus (Olney’s threesquare) was present at all reference sites. Juncus arcticus (wiregrass) occurred at 75% and Distichlis stricta (desert salt grass) was found at 50% of all reference sites. Other species that occurred included Alisma plantago-aquatica (water plantain), Potamogeton spp. (pondweed), Carex praegracilis (blackcreeper or clustered field sedge), Iris missouriensis (Missouri iris), and Asclepias speciosa (showy milkweed). Total vegetation

9 cover averaged 76%. In reference standard sites, the average species richness was eleven to twelve. The very invasive species, Lythrum salicaria (purple loosestrife) was been found at some sites. Water EC was about 2.2 dS and the pH was about 8.5. Soil EC was 2.4 and the pH was about 7.8. In hunting areas the soil lead content was often high. Many different species of waterfowl and shorebirds occurred at all of these subclasses. The exotic snail, Melanoides tuberculata, was collected at Fish Springs and has been reported at the Leland Harris complex.

In the Rocky Mountain / High Plateau Ecoregion, EC of the water averaged 1.04 dS and pH was 7.10. The soil pH averaged 6.4 and the EC was 0.85 dS. The calcium concentration of the water averaged 35 mg/l. Vegetation species richness was about 17 and the vegetation cover averaged 72%. Common vegetation species included Carex aquatilis (water sedge), Carex rostrata or C. utriculata (beaked sedge), Eleocharis palustris (common spikerush), Alopecurus aequalis (shortawn foxtail), Geum macrophyllum (large-leaved avens) and Ranunculus aquatilis (water crowsfoot). 5. Very freshwater (0.15 dS

10 Data summarization The invertebrate assemblages collected at each site were summarized with respect to taxonomic richness and assemblage composition. Comparisons in these measures were then made to assess differences among classes within each classification scheme. Mean values for each aquatic invertebrate metric were calculated and differences in metric values among classifications were evaluated using ANOVA and the Ryan-Einot-Gabriel-Welsch multiple range test (Table 1). Differences in assemblage composition among sites both within and across classification schemes were evaluated using mean similarity analyses. A number of metrics or ecological summaries were also calculated for each aquatic invertebrate sample. These metrics were primarily based on measures of taxonomic richness, because the goal of our sampling was to try and collect as many different taxa occurring at a site as possible within the sampling time and goal of collecting a minimum of 500 organisms. Richness is a component and estimate of community structure and stream health based on the number of distinct taxa. Taxa richness normally decreases with decreasing water quality. In some situations organic enrichment can cause an increase in the number of pollution tolerant taxa. Taxa richness was calculated for operational taxonomic units (OTUs) for the entire assemblage and the major orders of aquatic invertebrates found in wetland assemblages. The number of insect and non-insect taxa was also summarized. The number predators and non-predators, i.e., prey, were also calculated for each sample. The values for operational taxonomic units may be overestimates of the true taxa richness at a site if individuals were the same taxon as those identified to lower taxonomic levels or they may be underestimates of the true taxa richness if multiple taxa were present within a larger taxonomic grouping but were not identified. All individuals within all samples were generally identified similarly, so that comparisons in operational taxonomic richness among samples within this dataset are appropriate, but comparisons to other data sets may not. Sørensen coefficients (Romesburg 1984) were calculated for each pair of samples and used to quantify compositional similarities among sites within each

11 classification scheme. Similarities were calculated based on presence/absence data. Sørensen values range from 0 to 1 and describe the proportion of species shared between 2 sites. Following Van Sickle (1997) and Van Sickle and Hughes (2000) the strength of each classification scheme was determined by assessing the extent to which sites within groups were more similar to each other on average, than they were to sites in different groups. CS was calculated as follows. After calculating all pair-wise

similarities, the mean similarities among sites within each class (Wi), the mean within- class similarity among classes (W¯ ), and the mean between-class similarity (B¯) for each classification system were calculated. The CS of an individual class can be measured as either B¯/Wi or Wi−B¯, and the overall CS of a method is measured as either B¯/W¯ or W¯ −B¯. Strong classifications cause values of B¯/W¯ to be <<1 and values of W¯ −B¯ to be positive and large. In contrast, values of B¯/W¯ near 1 and W¯ −B¯ near 0 should occur if sites are randomly assigned to classes. Randomization tests (Van Sickle 1997) were used to assess whether observed CSs differed from randomly selected sets of data. These tests were applied to all a priori classifications. Classification strengths associated with each class within a classification were assessed by comparing

individual estimates of Wi with B¯. A list of the aquatic invertebrates collected at each site for each sampling date is provided in Appendix 1. This information was also summarized as the probability of occurrence of species, genera, and families by wetland sub class for reference and non- reference sites. The probability of occurrence was calculated by dividing the total number of individuals collected for each taxon by the total number of individuals of all taxa. These data were then converted to a percent occurrence within each wetland class and for all classes. These probabilities of occurrence profiles provide a great deal of information on the likelihood that a specific taxon will occur at a site and provides information on which taxa appear restricted to reference or non-reference sites. This information can be used in monitoring the success of a mitigation or restoration site, planning mitigation or restoration, as well as judging the current condition of a wetland.

12 Results Temporal variation Aquatic invertebrate samples were collected in the years 2000, 2001, 2002, and 2003 and in the months of April, May, June, July, August, September, and October (details provided in Appendix 1). We detected no statistically significant variation (ANOVA, p=0.05) in aquatic invertebrate taxonomic richness associated with either the year or the month the sample was collected.

Classification schemes With only one exception, wetland class – depression or slope, all apriori classifications showed statistical evidence (p<0.001) of greater CS then would potentially be seen for randomly grouped sites. However, the CS values were small indicating generally weak correspondence between the apriori classifications and wetland invertebrate assemblages (Table 1). Classification strengths (W¯-B¯) ranged from 0.5 to 8%, suggesting that in all cases less then 10% of the observed differences in assemblage composition among sites was accounted for by any of the apriori classification schemes. Classification strength was highest for wetland subclass and salinity and lowest for wetland class and reference status. Similar to the assemblage classification results, differences in taxonomic richness among most classes were small, but there was a strong trend for taxonomic richness to decrease with increasing salinity and decreasing water permanence (Figure1). Differences in mean richness values were greatest between salinity classes and water regime classes and lowest for reference status and ecoregion (Table 2). Reference class – Mean taxonomic richness was generally similar between reference and non-reference sites within all taxonomic groups (Table 2). Classification strength was statistically significant (p<0.001), but weak. Within group, assemblage similarities were similar for reference (0.18) and non-reference sites (0.19). Mean within ecoregion similarity was 0.18 and the similarity between ecoregions was 0.18. Values of B¯/W¯ were 0.97 and Wi−B¯ were 0.005 (Table 1).

13 Ecoregion classification – Mean taxonomic richness within all taxonomic groups was highest for sites located in the Wasatch and Unita Mountains, followed by the Colorado Plateau, and then Great Basin (Table 2). These differences however were generally non-significant. The only significant differences observed were for Coleoptera taxa where the Great Basin was significantly lower then the other two ecoregions. Classification strength based on ecoregions was statistically significant (p<0.001), but weak. Assemblage similarities were strongest for the Colorado Plateau and lowest for the Great Basin. Mean within ecoregion similarity was 0.20 and the similarity between

ecoregions was 0.17. Values of B¯/W¯ were 0.83 and Wi−B¯ were 0.03 (Table 1). Water regime – Mean taxonomic richness within all taxonomic groups was highest for sites located in permanent water sites, followed by semi-permanent sites, and then seasonal sites (Table 2). Classification strength based on water regime was statistically significant (p<0.001), but weak. Assemblage similarities were strongest for permanent waters and lowest for seasonally wetted habitats. Mean within ecoregion similarity was 0.25 and the similarity between ecoregions was 0.18. Values of B¯/W¯ were 0.89 and Wi−B¯ were 0.02 (Table 1). Wetland class – Mean taxonomic richness was higher in depression wetlands (mean = 24.8) as compared to slope wetlands (mean = 21.5) for all taxonomic groups (Table 2). Classification strength based on water regime was statistically significant (p<0.001), but weak. Mean within ecoregion similarity was 0.23 and the similarity

between ecoregions was 0.22. Values of B¯/W¯ were 0.97 and Wi−B¯ were 0.01 (Table 1). Salinity classes – Mean taxonomic richness within all taxonomic groups was highest for low salinity sites followed by moderate salinity sites, and then high salinity sites (Table 2). These differences however were generally non-significant. Classification strength based on salinity classes was statistically significant (p<0.001), but weak. Assemblage similarities were strongest for low salinity waters and lowest high salinity waters. Mean within class similarity was 0.18 and the similarity between

salinity classes was 0.25. Values of B¯/W¯ were 0.74 and Wi−B¯ were 0.06 (Table 1). Wetland subclass – Mean taxonomic richness was highest in subclass 31 and lowest in subclass 21 (Table 2). There was a strong trend for taxonomic richness to

14 decrease with increasing salinity and decreasing water permanence (Figure 1). Classification strength based on wetland subclasses was statistically significant (p<0.001), but weak. Mean within ecoregion similarity was 0.28 and the similarity

between ecoregions was 0.20. Values of B¯/W¯ were 0.73 and Wi−B¯ were 0.08 (Table 1).

Relationships with environmental variables There were few significant linear or apparent threshold relationships between aquatic invertebrate metrics and wetland vegetation measures, or water and soil chemistry. The strongest relationship with wetland vegetation was the relationship between total aquatic invertebrate taxa richness and wetland plant richness (Figure 2). Aquatic invertebrate taxa richness was significantly and positively related to wetland plant diversity (P <0.001, r2 = 0.28). Sites that supported a large number of plant species supported the highest number of invertebrate species. Other relationships between vegetation measures and aquatic invertebrate assemblage measures were non-significant, but the relationships were reasonable. Aquatic invertebrate taxa richness decreased with increasing bare ground and increased with increasing herbaceous vegetation. The only apparent or statistically significant relationship between aquatic invertebrate metrics and water or soil chemistry variables was between total aquatic invertebrate taxa richness and water total dissolved solids and water conductance, similar measures (Figure 3, relationship between taxa richness and electrical conductance shown). There was apparent threshold relationship between these variables, where above a certain level of dissolved solids (ca. 10 ds for electrical conductance), taxa richness quickly decreased and above this level, taxa richness was unrelated to dissolved solids.

Taxa occurrences The probabilities of occurrence by taxa within reference and non-reference are provided at the family (Table 3) and generic (Table 4) level. Several taxa appeared to prefer (>20% difference among classes) reference sites to non-reference sites; Coleoptera:

15 Hydraenidae, Heteroptera: Gerridae (water striders), and Odonanta: Libellulidae (damselflies). Similarly other taxa were much more prevalent in non-reference sites; Heteroptera: Corixidae, Notenectidae, and the snail Physidae. Similar tables were constructed to evaluate differences among wetland classes. These tables contain a considerable amount of information and are a bit difficult to interpret, but several general patterns emerged, including the obvious, but sometimes forgotten that there are a diversity of wetland types in Utah and that comparisons in expected condition need to be made within wetland types. Many taxa showed distinct preferences for certain wetland subclasses often without regard to reference condition.

39 Discussion The relatively low classification strength we observed was similar to that observed by researchers conducting similar work in North Dakota (Tangen et al. 2003) and Minnesota (Batzer et al. 2004). We observed the strongest classification strength as measured by B¯/W¯ and Wi−B¯ and overall differences in taxonomic richness among wetland subclasses. This is likely because wetland subclasses were derived based on measures of salinity and water permanence. Both of these individual classes were able to provide some discrimination in invertebrate assemblages, but neither was as strong as when the two variables were combined. This suggests that the relationship between invertebrate assemblages and salinity and water permanence is complex and the two factors work together to create habitat conditions suitable for different taxa. In similarly designed studies in the Midwest, Batzer et al. (2004) and Tangen et al. (2003) found few significant relationships between macroinvertebrate taxon richness and numerous environmental variables and the few significant relationships they observed were weak, explaining <20% of the variation in invertebrate assemblage richness measures. Two of the few variables that they found to be significantly related to taxon richness were a landform measure and a measure of hydroperiod (Batzer et al. 2004). These two measures were similar in spatial and temporal scale to our ecoregion and water regime designations. They found taxa richness to increase with decreasing canopy cover and increasing leaf litter input. They found no significant relationships between water chemistry variables and taxa richness or between pond basin size and taxa richness. The range of water chemistry variables in their study sites was much less than the range we observed, particularly in salinity. The general lack of a strong response of aquatic invertebrate assemblages to the environmental attributes measured by us and others that has been reported should not be viewed negatively. It may be explained by the generalist and somewhat tolerant nature of wetland invertebrates as compared to stream dwelling invertebrates, for which most of our understanding of invertebrate responses to pollution and land management actions have been formulated. In general, wetland invertebrates are more tolerant of fine sediment, lower dissolved oxygen concentrations, and warmer water temperatures

40 than many stream invertebrates. Wetland health assessments based of aquatic invertebrates may thus need to be developed with these life-history traits in mind and those that have worked well in streams and rivers may not work well in wetlands. In this particular study, we also sampled very few, if any, wetlands that were known to be severely degraded. The majority of our sites could be considered to be in reference or near-reference condition. The lack of any strong temporal summer variability in the invertebrate assemblages we collected was welcomed. This suggests that at least for permanent wetlands, assessment and monitoring samples can be collected throughout the summer months and compared. Based on our results and experience we recommend that samples be collected from permanent wetlands between May and October.

Future work Future work should focus on sampling sites that have been selected based on the wetland subclass and reference site designations. Currently there are too few reference sites that have been sampled within many of the wetland subclasses. These data generated to-date (Tables 3-7) contain very useful information for monitoring the success of a mitigation or restoration site, planning mitigation or restoration, as well as judging the current condition of a wetland. Additional sampling also needs to be done in sites for which we have apriori knowledge of degradation and some sense of what the major pollutants are at these sites. These data will allow us to then measure the sensitivity and response of the metrics calculated in this report to known pollutants.

57 Third Dam Ponds, UTWET-09 (thirddam) Cache County, Utah

This wetland pond (depression) may have been an old oxbow of the Logan River that was isolated from the river when Highway 89 was built. In July 2002, we sampled the north side of the pond (left side, as appears in photo). The substrate was rocky and silty on the several-foot- wide bench at the pond’s edge. Beyond this bench, the bottom dropped off steeply and we could not ascertain how deep the pond was. The vegetation survey was collected a week earlier. We returned to Third Dam in September 2002 so our new botanist could collect a revised vegetation sample. The sample collected in 2003 was done so for the Citizen Wetland Monitoring Comparison Study.

61 Salt Wells Meadow, UTWET-11 (swmonu2, swmonu3) Box Elder County, Utah, Great Basin ecoregion

This wet meadow is located in the Salt Wells wildlife restoration area, which lies at the tip of one northern finger of the Great Salt Lake, and is fed by the same spring as the Salt Wells- North Site sampled in 2001. However, UTWET-11 is located approximately .25 miles beyond the fence that protects the spring. The area was open to grazing in 2002. Saltgrass was the dominant vegetative cover and clouds of adult mosquitoes emerged from the grass when disturbed by our walking. The water was two to three inches deep with a silty, clay-like substrate. The top one- inch of the substrate was fine silt and the bottom layer, approximately five inches deep, was clay- like and compacted.

63 Lower Gibson Lake, UTWET-18 (gibsonlw) Franklin County, Idaho

This high altitude wetland depression was first sampled in 2001 and again in 2003. Potential impacts to the area are roads, recreation, and grazing. In 2003 the water was around one to four feet deep. The substrate was firm enough to sample the center as well as the periphery, although it became looser towards the center. The sample was collected from the north, east and south shores. The vegetation in the wetland was composed primarily of sedges (Carex) and the aquatic vegetation covered approximately 35% of the open water.

65 Upper Gibson Lake, UTWET-19 (gibsonup) Franklin County, Idaho

This high altitude wetland depression was first sampled in 2001 and again in 2003. Potential impacts to the area are roads, recreation, and grazing. The perimeter of the depression is composed of deep, thick mud, which made it difficult to collect the samples both years. This perimeter could also be described as quaky or boggy. Because of the instability of this soil we were unable to sample the center of the wetland. The open water in the depression’s center was approximately 85% covered with aquatic vegetation.

67 SLC Airport 2, UTWET-20 (airprt22, airprt23, airprt24) Salt Lake County, Utah, Great Basin ecoregion

Historically this site was a natural playa, but the hydrology has since been altered. Cattle grazing was supposed to be prohibited in this airport mitigation site, however, when we sampled in 2002 there was evidence of grazing in the form of recently dried hoof prints in the mud. Shorebirds were feeding at the site. The substrate was composed of two distinct layers: four inches of organic material lay on top of a denser layer of clay. The water had a distinct reddish tint. Salicornia dominated the vegetation, but saltgrass and Phragmites were also present. Phragmites is a native, but invasive species scattered in patches at the north end of the site.

When we sampled in 2003 the water level was much higher and, according to the electric conductance readings, the water was less saline. As stated above, the water cycles and sources have been altered from their natural state, so it is not surprising that the water chemistry was so different. The vegetation, however, had not changed. Ibis, willets, blue herons, and unidentified ducks were feeding on the playa and carp were mating in the one to two foot deep water. The water had the same reddish tint as in 2002. We observed a beaver running out on a peninsular upland area. Because of impending thunderstorms and time constraints, the invertebrate sample was preserved and sorted back at the laboratory.

69 Lower West Pond, UTWET-23 (lwest2, lwest3) Salt Lake County, Utah, Great Basin ecoregion

Lower West Pond was also sampled in 2001. The site is part of the Kennecott Copper Mine’s mitigation project located on the south shore of the Great Salt Lake, the Inland Sea Shorebird Reserve. The I.S.S.R. is also used for wetland education purposes. Avocet and ibis both were feeding while we collected our samples. The site was dominated by hundreds of copepods, but because they are zooplankton only several were picked for the qualitative sample. The substrate was light in color, muddy, and approximately four inches deep. Phragmites (a common invasive species) grew in large stands all around the site. However, if the site was more balanced in health it would be dominated by a saltgrass community. Saltgrass was present, but not in the proportion expected for a healthy wetland.

70 Blue Lake Upper Playa, UTWET-34 (blplay3, blplay4) Tooele County, Utah, Great Basin ecoregion

The water source for the 2002 sample was the same as the 2001 site so they both share the name UTWET-34. However, the 2002 sample was collected from a location in better shape and further from the Blue Lake “parking lot” than the 2001 location. Typical wetland vegetation was found here (Salicornia and saltgrass), in addition to the less common Bird’s Beak and other species that could not be field-identified. As we walked through the water, several spots were noticeably cooler, suggesting the presence of subsurface springs.

72 Blue Lake Upper Springs- UTWET-35 (bluespgu, bluespgu2) Tooele County, Utah, Great Basin ecoregion

We first sampled this site in 2001 and returned to this site during the 2003 season. Hydrometridae were found living in this spring-fed wetland pond. We had previously only found this allusive family at the Blue Lake- Upper Pond site. A large leech was also collected here. The open water is surrounded by a dense growth of bulrush, while the outskirts of the site are dominated by saltgrass and Salicornia.

74 Blue Lake Upper Pond, UTWET-36 (bluepd1, bluepd2, bluepd3) Tooele County, Utah, Great Basin ecoregion

When this site was sampled in 2001 (UTWET-36) a rare Hemiptera genus (Hydrometra) was collected. Finding another of these specimens was the goal at this site in 2002, a difficult endeavor because the bug populations here are sparse. Nancy Keate suggested that the combination of high pH and electric conductance levels could be cause for the lack of bugs. It took two people three hours to collect our 156 specimen qualitative sample. However, we were successful in finding two Hydrometra on site. In addition to the field qualitative sample, several scoops of material were collected in a jar for later inspection back at the laboratory. The vegetation was typical of wetlands, but consisted primarily of saltgrass. There was very little vegetation growing in the water, but a few patches of rushes and sedges grew at the edges. The substrate in the open water was approximately two feet at the deepest and was loose in composition.

In 2003, again we searched for Hydrometra at this site, but none were found either in the field sample or the material that was sorted back at the laboratory. After almost two hours of searching for invertebrates we only had 55 bugs, so the remainder of the sample was placed in a jar and sorted later in the lab. The hydrology of the site had changed; the pooled water to the west of the main site had moved much closer to the road (north). In addition to saltgrass our botanist also identified Bird’s Beak this year.

76 Horseshoe Spring- UTWET-38 (horsesh1, horsesh2) Tooele County, Utah, Great Basin ecoregion

To locate this spring, drive west from SLC on I-80 and take road/exit 196 South. It is marked by a BLM sign. This moderately saline spring system has been altered from its natural flow, most likely dredged. The water now flows into pools connected by shallow streams and slopes. There was abundant wildlife present, compared to other sites we have sampled. Two snakes slithered by us and several curlew were walking through the grass near the parking area. One solitary grebe was swimming around the pond where we collected our samples. A man was fishing for the large mouth bass, most likely stocked, we saw in the pond. Mosquitoes, dragon and damselflies were out in full force the afternoon we sampled. We collected quite a diversity of macroinvertebrates. This site was also sampled in the 2001 season.

78 Dry Lake- south, UTWET-39 (drylake, drylake2) Cache County, Utah

Prior to sampling Dry Lake in 2002, we obtained permission from the property owner, Donald Jeppessen. He can be reached at either (435) 753-5838 or 512-3916 for future access. His property lies south of the east-west running fence that bisects this wetland depression. Based on the different dominant vegetation types growing in the north and south regions of the site, we decided to collect two separate samples. The south site’s vegetation sample primarily revealed Eleocharis and pondweed. The water was approximately three to five inches deep, with deeper water towards the north or center of the wetland. Two tadpole shrimp were collected at this site in 2002, a rare and beautiful find. Due to time constraints only 300 invertebrates were collected on June 20th, but the site was revisited on June 22nd when 200 more organisms were collected to ensure a complete qualitative sample.

In 2003, we combined the north and south sites into one. The water depth from the edges to the center was about two inches to two feet, similar in depth to the previous year. We noticed yellow-headed blackbirds and killdeer flying through the sedges and rushes, and heard an elk

bugling in the distance.

81 Dry Lake- north, UTWET-40 (drylake) Cache County, Utah

This site is contiguous to UTWET-39, but a separate sample was collected in 2002 from this central region of the wetland. The vegetation in this section was much taller, primarily bulrush, and the water was deeper at 12 inches. Particulate vegetation and fine silt composed the one- inch deep substrate. In the process of sampling, we discovered several bird nests hidden within the bulrush. As with UTWET-39, we initially only collected 300 invertebrates, but returned on June 22nd and collected 200 more to complete the 500 bug qualitative sample. In 2003, this sample area was combined with UTWET-39 to make up one site.

83 TNC Lake Pond, UTWET-41 (tncpond) Davis County, Utah, Great Basin ecoregion

This site is located approximately .5 miles southeast of The Nature Conservancy Playa- site 1 (UTWET-07) that we sampled in 2001 and, therefore, is closer to the Great Salt Lake shore. The playa we intended to sample was completely dry. This pond was an unexpected discovery located approximately 200 yards south of the playa. Deer and coyote tracks were visible in the soft playa soil and there were several coyote burrows on the periphery of the site. When we first approached the pond, we flushed eight ibis from the surrounding vegetation (primarily bulrush). This shallow depression had a one-inch deep slick, silt substrate and one to three inches of standing water.

85 2600 N Lane Playa, UTWET-42 (nolanepl, nolanepl2) Cache County, Utah

Eve Davies, Pacific Corp’s Cutler Marsh Environmental Coordinator directed us to this site. She can be reached at 801-220-2245 or 232-1704. The public is allowed unlimited access to this site. However, the fence leading into it is not marked as such. The site includes both playa and wet meadow areas. In July 2002 there was still some water on the playa edges- an inch or less deep. The playa vegetation included bulrushes, sedges, Salicornia, and saltgrass. Salicornia, greasewood, and assorted grasses grew on the upland areas. We noticed deer tracks in the playa mud and several canine burrows to the southwest where we found many scattered bird wings, feet, and feathers. Nancy Keate suspected these were foxholes as foxes are notorious for preying on wetland birds, where coyotes are not.

We returned to this site in September 2002 so our new botanist could review the vegetation survey taken in July. At this late date in the season the water had receded off the playa, but was still standing at about one inch deep in the bulrushes and some moisture was evident in the saltgrass directly surrounding the rushes. There was one small pool (four inches deep) in the sedges at the edge of the bulrushes. We were surprised to find any water at all; the water source is either a spring or irrigation run-off. An odd “sizzling” noise was coming from the bulrushes. We followed the sound into the bulrushes where we observed thousands of snails moving across the surface of the mud.

When the site was sampled in 2003, more water was on the playa than previously observed in years past. At least one inch of rain had fallen in Cache Valley the past weekend. Water depth was approximately two inches on the playa mud flats. The weather was still cool and windy from the weekend’s storms. Sandpipers, blackbirds, and other songbirds were observed at the site and we could hear thousands of birds from the Cutler Marsh rookery one mile to the south.

90 Soldier Hollow Upper, UTWET-43 Wasatch County, Utah

Nancy Keate has been monitoring the Soldier Hollow sites for the Corps of Engineers. This is a mitigation project to replace wetlands destroyed by the Wasatch Mountain Parks development for the 2002 Olympics. These sites were included in our study as comparisons for other high altitude reference wetlands. Historically hay was planted in the upper site. Some moisture seeps down into it from an upslope irrigation ditch (located to the north and west of the field). In attempts to create a wetland meadow here, water has been allocated from this same ditch and released down the slight slope. Also, there is a small seep at the bottom one-third of the site that contributes some water to the site.

The water forms a small, meandering stream revealing a substrate of small rocks and fine sediment. The water source is relatively fresh and not allocated for any other purpose before reaching this site. However, a golf course is being built to the north and this ditch flows through the construction area. Unfortunately the ditch pipes were crushed several times during the 2002 season, inhibiting the water’s flow and interrupting the establishment of the wet meadow. The established vegetation has predominantly grassland characteristics, but the Corps of Engineers planted many wetland shrubs and plants (in photo, see yellow mesh to the left of stream) in hopes that the site would take on wetland characteristics. Only 300 bugs were collected in 2002. The habitat did not yet seem ideal for an established aquatic invertebrate population.

In 2003 the canal was flowing at 380 cfs and the small stream soaked into the slope midway down the site. Keate, the Corp representative, and the park manager determined that this was not sufficient flow for wetland establishment. They decided that the ditch should be expanded to allow water to flow onto the slope from the top west end of the slope. They also decided that the water flow should be increased to 450 cfs, but ensuring that the ditch was dug to the correct specifications and that the water consistently flowed at the correct cfs proved to be a challenge. Again, only 300 macroinvertebrates were collected.

93 Bear River Bottoms, UTWET-44 (bearrvb1, bearrvb2) Cache County, Utah, Great Basin ecoregion

Bear River Bottoms is an old oxbow of the Bear River located approximately a quarter mile west of the river’s main channel. Because the depression is isolated from any inflow or outflow, the water level fluctuates with seasonal precipitation levels. The Division of Wildlife Resources leases this land from Pacificorp. Samples have been collected from this site for both the Utah Wetlands Study and the Citizen Monitoring Comparison Study.

The site was visited four times during the 2002 season. However, in May and November invertebrate samples were not collected. In July, when the invertebrate sample was collected, the water level was about one foot at the deepest spot sampled. In the shallower water thick algae and vegetation had accumulated. Plants with small white flowers were also growing in the water.

Our new botanist collected new a vegetation sample in September. The water had dried to eight inches below the substrate surface, visible in wide cracks. We dug holes big enough to scoop up material with the kick-net. We allowed the water to pool and the mud to settle before collecting bugs. The bugs were decanted from the mud in a bucket, poured through a 500-micron opening sieve, and picked through as a qualitative sample. We also scooped mud into jars to be cleaned and picked through at the lab. Willow, cattail, sedges, and rushes were identified in the depression, but the upland area had a high “weed” component of prickly lettuce. By November, Cache Valley had received several inches of rain and snowfall, which raised the water level again. The substrate still had deep cracks in it from the last time it had dried.

In 2003, our botanist identified cattail, sedges, willow, thistle, teasal, and Allysma growing at the site. It appears that the vegetation growing in the pond’s center is slowly taking over. We observed ibis, pair of ducks, and yellow-headed blackbirds feeding at the depression. We also collected a two-inch long larval beetle emerging from the pond’s still moist periphery- a Hydrophillidae possibly preparing to pupate.

98 Soldier Hollow Lower, UTWET-45 (shponds, shponds2) Wasatch County, Utah

This is the lower site of the two Soldier Hollow mitigation sites. The lower site is comprised of three depressions connected by short, southwest flowing meanders. In both 2002 and 2003 the qualitative sample material was collected from all three depressions and sorted as one sample. The water that feeds this site flows down-slope from the upper site and, thus, is also affected if the canal does not provide sufficient water. In 2003 we sampled the lower site the day following Keate’s meeting with the other wetland managers. The canal flow had been increased to 450 cfs as discussed, but the influence of the increased flow was not yet apparent. Substrate in each of the ponds was one to three inches deep and composed of an organic, clay-like material. As in the upper site, they have planted wetland shrubs and other plants here, but there are still many thriving non-native vegetation species.

101 Layton Marsh site 2, UTWET-46 Davis County, Utah, Great Basin ecoregion

Layton Marsh 2 is located about one half mile southeast of the Layton Marsh (UTWET-06) site sampled in 2001. This site had a healthy diversity of vegetation. It was flanked to the north and south by tall rushes and cattails, with knee-high grasses and Salicornia growing between those flanks. All water at this site was either lying beneath mats of long grasses or in small, shallow depressions and was approximately one foot at the deepest spot. The substrate was mostly composed of broken-up vegetative debris. The center of the site was dry.

103 Playa South Hull Lake (P.S.G.), UTWET-47 (sohull, sohull2) Box Elder County, Utah, Great Basin ecoregion

This playa is located at the south end of Hull Lake and the southernmost end of the Public Shooting Grounds’ dike/road system. The site includes open water, a narrow playa area, a mid- level bench, and an upland area created by the dike. The photo is taken from the upland area. To reach the open water in 2002 we had to traverse through thick mud and dense, saturated aquatic vegetation. The water was between three and six inches deep where the invertebrates were collected. Greasewood shrubs, various short grasses, sedges, and pickleweed dominated the vegetation survey. We observed canine tracks on the mud’s surface.

The bugs were collected from the same area of the playa in 2003- submerged vegetation and completely saturated playa mud. At this earlier time in the season the water was at least six inches deep; the air and water were much cooler. Dormant greasewood and wheatgrass grew on the upland area, while saltgrass and bulrush grew on the playa below. We observed coots, snowy egrets, and white-faced ibis feeding at the outskirts of the site.

106 Duck Lake Playa (P.S.G.), UTWET-48 (duckply, duckply2) Box Elder County, Utah, Great Basin ecoregion

In 2002, Duck Lake was the northernmost open water area (east side of dike/road) we came across after entering the Public Shooting Grounds. When we approached the site ibis, avocets, and stilts were feeding at the playa in the shallow, open water. They moved further into the lake when we began sampling. There were several emergent patches of vegetation (small, saturated islands) in the open water. The water was about six inches deep where the bugs were collected. The thick mud between the playa and open water was very difficult to walk through. The playa vegetation was primarily pickleweed. Shrubs (including greasewood) and grasses dominated the steep slope that led up to the dike/road/upland area.

We sampled several months earlier in the 2003 season, so the water was about twice as deep, standing at one foot. Saltgrass and Salicornia were the dominant vegetation on the playa’s periphery. This year we observed two sand-hill cranes and avocets feeding at the site and hundreds of sparrows that had built mud nests under the eaves of nearby outhouses.

109 Cement 1 Pond, UTWET-49 (cement) Tooele County, Utah, Great Basin ecoregion

This site is located north off Ellerbeck Road near Grantsville. Cement 1 is a small pool within a spring-fed, depressional meadow. Directly south, across the road, is an operating limestone- processing factory. The presence of the limestone factory indicated that the geology of the area might be conducive to springs and, thus, the source of this water. There was evidence of grazing and vehicle tracks through the wet meadow. “Playa-like” vegetation, such as saltgrass, Salicornia, greasewood, and Bird’s Beak dominated the area. Bird’s Beak is a plant commonly found near hot springs. The pond was approximately five by eight feet and one foot deep with a loose, almost fluffy, substrate light tan in color. Scuds and Hemiptera were the primary bugs collected.

110 Limestone Playa, UTWET-50 (limest1, limest2) Tooele County, Utah, Great Basin ecoregion

Limestone Playa is located approximately two miles west of the limestone-processing plant on the north side of Ellerbeck Road near Grantsville. Railroad tracks and I-80 were visible about two miles north of the playa. Salicornia, Bird’s Beak, and saltgrass grew at the south end of this site- typical playa vegetation. In 2002, the entire site was dominated by pure salt and was pure white. Despite the 80° air temperature, the site emulated a frozen lake. The combination of water and salt crystals created the feel and look of ice slush and the areas where water had receded looked like snow drifts. Top to bottom the vertical profile of the salt flat was as follows: opaque film with floating salt pieces, one to two inches of water where an occasional brine shrimp would be found swimming, two inches of solid salt crystal where several adult bugs were encased, a thin layer of red material (possibly bacteria), then very black mud. Only 52 bugs were collected at this site; most were already dead and encased in salt.

When we returned in 2003, there was more water on the playa than the previous year and the salt-scape was diminished. The increased water level on the playa and the lower air and water temperatures may have been the factors that resulted in the increase in the macroinvertebrate populations. We were able to collect a complete qualitative sample this year. Several avocets and willets were observed feeding at the site. Saltgrass, two species of Salicornia, and

greasewood made up the vegetation survey.

112 Plover Playa, UTWET-51 (plover, plover2) Tooele County, Utah, Great Basin ecoregion

Plover Playa is also located off Ellerbeck Road near Grantsville. Turn north a half mile west of the limestone-processing plant onto a wide dirt road. The playa is located off the east side of this road/dike. Interstate-80 is only a half mile to the north. When we sampled in 2002 there were several snowy plover feeding in the shallow water. As we explored the site, we discovered canine tracks in the soft mud and two ground-nesting bird nests- either avocet or black-neck stilt (identification based on the hollow egg that was found in one of the nests). Saltgrass and Salicornia were virtually the only vegetation growing here in scattered patches. While traversing the playa we sank about one inch into the clay substrate- identified as a glade soil. This substrate, paired with the shallow water (one inch deep or less), made it difficult to scoop up sample material. The qualitative sample did not yield a great diversity of invertebrates, but those that were collected were plentiful.

When we returned in 2003, as with Limestone Playa, there was more water on the playa than last year, but fewer shorebirds. We did find one empty eggshell. The water’s dilution of the glade soil substrate actually made it easier to walk through. It had a soup-like consistency rather than last year’s thick mud. The substrate had a distinct sulfur aroma.

114 Bulrush Pond, UTWET-52 (bullrbl) Tooele County, Utah, Great Basin ecoregion

This is another site located off Ellerbeck Road near Grantsville, with the limestone-processing plant approximately one mile to the east. The water flowed southeast to northwest through this site, with a back-flow pool forming to the south. The invertebrate sample was primarily collected from this pool. We suspected that the water source was a nearby spring. A four foot wide corridor of bulrush framed the water, but beyond that saltgrass and Salicornia dominated the site. As we followed the water source to the southeast, we found many sunflowers growing on either side of the water channel. The substrate was a very organic, thick black mud. Only 300 invertebrates were collected because only scuds, Chironomids, and several types of odonates were repeatedly found. It would have been redundant to collect more.

116 SLC Airport 3, UTWET-53 (airprt33, airprt34) Salt Lake County, Utah, Great Basin ecoregion

SLC Airport 3 is also a mitigation site for the airport, located on the west side of the road from SLC Airport 2. When we sampled in 2002, black-neck stilts, ibis, and avocet were all feeding at the site, but moved further north into the water when we arrived. The site’s substrate had a deeper top layer than Airport 2’s and seemed to contain less organic material. Salicornia and saltgrass grew on the upland areas and scattered patches of Phragmites grew at the north side of the water.

There were not many birds present when we returned in 2003. The weather was cool and blustery and a storm was approaching from the west. Because of the storm, the invertebrate sample was preserved in a jar and brought back to the lab. The botanist identified saltgrass growing in the playa and on the upland, as well as rubber rabbit brush and greasewood.

Phragmites grew on the west side of the site.

118 Sims Pothole 1, UTWET-54 (sims1) Uintah County, Utah

The Sims Pothole region is comprised of a series of wetland depressions (potholes) in a high altitude setting. This pothole is located 0.9 miles north of the Sims Peak turn off on the Red Cloud Loop Road in the Ashley N.F. and is visible to the west from the road. Grazing and silviculture operations were in progress near the site, informing us that the Red Cloud Loop’s is heavily trafficked by not only recreationalists, but also timber and cattle vehicles. Even with these impacts, the proximity of the wetland to the road did not seem to impact its viability. It was in surprisingly good health with a diversity of invertebrates and vegetative cover. Sedges surrounded the open water. Lodge-pole and ponderosa pine trees encircled the greater site. Approximately five different types of Carex and five different types of grasses grew there as well. Many large odonates and Chaoboridae were collected. The substrate was composed of 12 inches of bound up organic matter at the north end and six inches of sandy, reddish soil with organic matter underneath at the south end.

120 East Marsh Lake, UTWET-55 (marsh3) Summit County, Utah

East Marsh Lake is located within the Wasatch-Cache National Forest, but is accessed by driving south out of Mountain View, Wyoming. This approximately 30 foot diameter wetland pothole is not officially named, but can be found on the east side of FS Road 410, just south of the West Marsh Lake Campground turnoff. Lily pads covered much of the open water. Shrubs, very short willow (clipped by grazing animals), sage, and ponderosa pine all grew on the upland areas. Many plant species were identified here, which in part may be due to overgrazing. The disturbance caused by the cattle may open the site up to plants that thrive in such conditions, such as red clover.

The area has a unique “micro topography”. There was a slight difference in elevation within the site; the upland soil was hard and dry, but the land became increasingly moist, springy, and spongy towards the open water. A change in vegetation types was perceptible at the boundary between dry and moist soils. The soil at the water’s edge was super-saturated and would collapse into the water if too much pressure were applied. Cattle could probably not drink from this pond because of the instability of the banks. We could not measure the water’s depth, because the bottom dropped out sharply at the pond’s edge. One tiger salamander and one small striped frog were captured in the kick-net. The salamander had not yet morphed into an adult; it still had gills. Both amphibians were released after observation.

122 Cook Pothole Lower, UTWET-56 (coookhplw) Wayne County, Utah

Both the upper and lower potholes are located in the Dixie N.F. off the road to Boulder Mountain Top and north of the main Cook Lake. It appeared that the upper site flows into the lower during high water. Grazing and recreation may impact the area. A steep scree field bordered the site to the east. This pothole was less diverse than the upper site. It was a grass-covered depression with shallow water in the center. It was difficult to sample here because a periphery of thick, deep mud lay between the open water area and the edge. However, big rocks were scattered around the edge, which enabled me to reach the open water to collect the invertebrate sample. Anostraca were collected here.

124 Aquarius Pothole, UTWET-57 (aquarius) Wayne County, Utah

This pothole is located in the Dixie N.F. off the road to Lava Spring and Dark Valley Draw. The site is comprised of two depressions that are connected during high water, as evidenced by the dry channel between the two and identical water level rings around the base of nearby aspen trees and rocks. At the extreme periphery of the site, dead tree trunks were “beached”. The west depression seems to be more permanent than the east one, evinced by the soft, mud substrate and the presence of numerous salamanders. The water was four to five feet deep. The east depression had shallow water and a cracked mud substrate, as if the water had dried completely in the past, and no salamanders were present. The water was two to three feet deep. To the north of the depressions were several dry rivulets that drain water into the site. The botanist identified sedges, grasses, conifers, and aspen trees. Potential impacts to the site were grazing, recreation, and the presence of a youth-at-risk wilderness program.

126 North Playa, UTWET-58 (northpd) Salt Lake County, Utah, Great Basin ecoregion

North Playa is located within the Kennecott Copper Mine’s mitigation project. The I.S.S.R. is also used for wetland education purposes. This was the most saline I.S.S.R. sample site. The southern shore of the Great Salt Lake was visible to the west, although a mile or more of “beach” separated the actual lake from the wetland (most likely due to the effects of the summer’s drought). Several young avocets, and later ibis, fed at the site while we were sampling. Salicornia dominated the upland vegetation, with several bunches of grasses intermixed. In the distance, several Phragmites stands were observed growing along the water’s edge. An interesting find at this site was the euridic soil, which is made of brine shrimp feces encased in hard, mineral substances. The substrate was also made up of this soil, forming a loose one-inch deep layer.

128 Dry Lake mud sample, UTWET-59 Cache County, Utah

In 2002, we returned to Dry Lake so that our new botanist could review the vegetation survey collected on June 20th. There was no standing water at either of the sites sampled in June, so no water or on-site invertebrate samples were collected. We hiked further into the center of the depression to search for water, but found none. A mud sample was collected from two different areas. Back at the lab, these samples were rinsed through a 500-micron opening sieve and then the remaining material was picked through as if it was a qualitative sample.

South Pond is located within the Kennecott Copper Mine’s mitigation project, as well. The I.S.S.R. is also used for wetland education purposes. This site has small shelters (as seen in the background of the photo) located around its shores, which are used for Kennecott’s educational programs. October 1st was a very cold, rainy, and windy day for sampling and the last day of our 2002 sampling season. Fingers were numb by the time 500 bugs were picked. The rain and wind churned up the substrate in the water causing a murky appearance and an odd film on the water’s surface. Four vegetation species were present: Phragmites, Salicornia, bulrush, and saltgrass.

133 Salt Wells Playa, UTWET-69 (swplaya3) Box Elder County, Utah, Great Basin ecoregion

This ephemeral playa is located in the Salt Wells wildlife restoration area, which lies at the tip of one northern finger of the Great Salt Lake. The site was dry despite several one to two inch deep depression areas where sparse invertebrate samples were collected. Nancy Keate had previously sampled here, but never for macroinvertebrates. When we sampled this area in June 2001, the site was completely dry. Emergent saltgrass grew adjacent to the roadside, the south boundary of this site, but no other vegetation grew anywhere else on the playa.

134 TNC Playa (managed), UTWET-70 (mtncply) Davis County, Utah, Great Basin ecoregion

This site is located just north of UTWET-07 on The Nature Conservancy property. Water had never before been observed on this playa, making this site a unique find. However, when we tested the water chemistry the salinity was much lower than expected, indicating a fresh water source. Upon closer inspection we discovered the water source to be a small north to south running ditch. Because the water source was suspect this site could not be used as a reference site in our study. Samples were collected for the sake of interest. The playa had a slick, clay substrate and one to two-inch deep water. The primary vegetation was Salicornia and saltgrass. The saltgrass was another indicator that the water’s presence was not a naturally occurring hydrologic phenomenon. Saltgrass is not typically found on playas. Natural or not, the birds were taking advantage of this water. We witnessed several geese feeding there.

136 Goshen Playa, UTWET-71 (goshenp3) Utah County, Utah, Great Basin ecoregion

Water was absent from this ephemeral playa depression when we attempted to sample here in 2001 and 2002. In 2003, we were able to sample early in the spring when the site was still watered. The invertebrate sample was collected from the north and east shore because the wind was blowing from the southwest and the wind congregated the bugs into that area. Two dominant invertebrates were collected: Anostraca and Culicidae. Several kildeer were observed at the site.

This ephemeral playa is located in the vicinity of UTWET-29, 30, and 31 and on Division of Wildlife Resources property. Again, because we sampled so early in the spring, water was plentiful on this playa and many birds were taking advantage of this fact. Geese, sand-hill cranes, songbirds, and other migratory birds were observed or heard nearby. Ninety-nine percent of the vegetation was saltgrass. The depression was flanked by an upland area to the east and surrounded by saturated saltgrass on all sides. The water was approximately five inches deep at the center. The water had an orange tint, evidence of a mineral presence in spring-fed depressions.

139 Davis Creek Ponds (S and N), UTWET-73 (davispnd, davispnd2) Davis County, Utah, Great Basin ecoregion

These wetland ponds are located within the Farmington Bay Wildlife Management Area. They were sampled on two separate occasions: from the south shore in May and from the north shore in July. This pond has the freshest water of any in the management area. Its water source is Davis Creek, which has not been as negatively impacted as the water sources that feed the other impoundments. Thus, the water likely had the lowest phosphorus levels.

On the south side the vegetation was bulrush, cattail, pondweed, and cottonwood trees. We observed yellow-winged blackbirds and heard the song of a ricket (rarely visually observed). Three deer watched us carefully from the south side of the dike. The sample was collected from the southeast corner of the pond where the water was one to two feet deep in the cattail and bulrush stand. The substrate was a loose organic material.

The north side was dominated by thick stands of cattail and sedges which were difficult to maneuver through to get to an open spot where bugs could be collected. The vegetation and water chemistry data had been collected on an earlier trip.

142 Second Impoundment W and Davis Creek Second, UTWET- 74 (2ifbwma, 2ifmwma2) Davis County, Utah, Great Basin ecoregion

These wetland ponds are two of many impoundments within the Farmington Bay Wildlife Management Area that filter treated effluent water from the North Salt Lake City, South Davis North, and South Davis South facilities. Treated wastewater accounts for 50% of the impoundments’ water sources and the other 50% most likely comes from nearby Davis Creek.

Although this site is rather impacted, there was a good diversity of macroinvertebrates when we sampled in May. The substrate was dark and smelled of rich organic matter, a result of high sulfite and mercaptans from the effluent water source. The vegetation was saltgrass, cattail, Phragmites, bulrush, and duckweed. Wildlife was abundant with ibis, 3 blue herons, snowy egrets, coots, yellow-headed blackbirds, marsh wren, and canine scat found at the site.

In July we sampled the eastern half of the impoundment that lies east of the dike. The water was very warm and murky. Many small, dead fish lay at the water’s edge. The vegetation survey and water chemistry data were collected several weeks earlier. The diversity of aquatic life was much lower than that of the western side.

145 State Canal, UTWET-75 Davis County, Utah, Great Basin ecoregion

This canal carries treated effluent (waste) water from the North Salt Lake City, South Davis North, and South Davis South facilities. It feeds many of the impoundments within the Farmington Bay Wildlife Management Area. The aroma of chlorine was very apparent from the treated water. The canal had wetland-like fringes. This site was relatively depopulated of invertebrates, although frogs/toads, a water snake, and carp were observed. The vegetation consisted of Phragmites, bulrush, and wild iris.

147 TNC Tower Pond, UTWET-76 (towerpd) Davis County, Utah, Great Basin ecoregion

The Nature Conservancy recently completed the Great Salt Lake Shorelands Preserve, formerly the Layton Wetland Preserve, which expands citizen access to 3,200 acres of the Salt Lake shore ecosystem. TNC built a nature center, an observation tower, and a boardwalk loop over the playas, mud flats, and ponds that border the lake. This new preserve is located southwest of UTWET-46. We were able to use the boardwalk to get to this otherwise inaccessible wetland system that is located south of the observation tower (shown in the photo below).

This pond had plenty of water, most likely supplied by groundwater seepage from the Kays Creek delta to the east. The water is not managed and therefore this wetland may be used as a reference condition site. From the tower it is apparent that this wetland is one of many that span many acres. Phragmites, sedges and grasses make up the main vegetative cover. Fortunately, the Phragmites here has not invaded the area to the extent observed at many Utah wetlands with managed water sources. In the tall sedges we found several marsh wren nests and adults. Shorebirds were plentiful, as well.

149 Large Pond Burr Trail, UTWET-77 (burrpond) Garfield County, Utah, Colorado Plateau ecoregion

This pond is located off Burr Trail Road a few miles southeast of the town of Boulder and near the Grand Staircase-Escalante National Monument boundary. It appeared to be man-made, but was well established. There was a small dam and outflow at the eastern shore. There was also evidence of grazing. Strong vegetation diversity was apparent, including upland growths of sage, pinyon, juniper, cottonwood, ponderosa, and blooming desert flowers. Healthy stands of Surpus maritimus (bulrush) and willow grew at the pond’s shore, but the invertebrate density was not correspondingly high.

151 Highway 12 Tinaja down slope, UTWET-78 (tinajad) Garfield County, Utah, Colorado Plateau ecoregion

This site is located within the Grand Staircase-Escalante National Monument. The wetland, tinaja pool is fairly well established and oftentimes has water in it. At this visit, however, the water was low with about four feet of exposed bank. The substrate is sand and some organic matter. Even though this site is located directly below Highway 12, it is in relatively good shape. Tadpoles, almost morphed into frogs, were observed, as well as several orange-red adult dragonflies. The vegetation consisted of Russian olive, Carex, sedges, cottonwood, desert flowers, and willow.

155 Upper Calf Creek Falls Tinaja, UTWET-80 (calfcrkt) Garfield County, Utah, Colorado Plateau ecoregion

We discovered this series of plunge pools while searching for other previously sampled sites in the Upper Calf Creek drainage, within the Grand Staircase-Escalante National Monument. To access this site, hike above Upper Calf Creek Falls and cross the creek. Hike upslope, over and to the left of the small ridge. The two pools are visible from the ridge top. We intended to sample both pools, but an impending storm prevented us. The site is in a potential flash flood path. During storms when these pools fill completely, it appears that they pour off the cliff and feed the alcove pool below.

We only collected 125 bugs before abandoning the sampling effort. The rest of the sample was placed in a jar for examination back at camp. We lost a large adult beetle in the process. There was not much vegetation directly adjacent to the pool habitat, but in the upland areas we recorded shrubby pinyon, yucca, prickly pear cactus, and sagebrush.

158 Amalga Barrens, UTWET-82 (amalgabn) Cache County, Utah, Great Basin ecoregion

This slough and playa site is located on Audubon property and was sampled for the Citizen Wetland Monitoring Comparison Study. When we first sampled the site in June 2003 the weather was uncharacteristically cold, windy, with overcast skies. However, we did observe many shorebirds: avocet, stilts, and blue heron. There was also a small beaver dam, as seen in below, left photo. The vegetation was primarily composed of saltgrass and Salicornia. The weather was much calmer when we sampled in September.

161 Goose Island Alcove, UTWET-83 (gooseis) Grand County, Utah, Colorado Plateau ecoregion

This site is located off Highway 128, along the Colorado River. We initially visited this site to sample a plunge pool that is typically full, but it appeared that the pool had recently dried up. We did find a small hanging garden fed by a seep above the pool. The seep had saturated the ground below the garden where we discovered several one-inch deep puddles from which we could collect an abbreviated qualitative sample. Several damselfly larvae, adult beetles, Stratiomyidae, and Hemiptera were collected. We hope to compare these specimens to organisms collected here in the future. We purposely did not collect many specimens, because the water was so low and we did not want to deplete what invertebrate populations were surviving there.

162 West Coyote Plunge Pools, UTWET-84 (wcoyote) San Juan County, Utah, Colorado Plateau ecoregion

To locate this site, drive south from Moab on Highway 191 and turn west onto Flatiron Bench Road. To access this remote series of plunge pools requires driving on technical four-wheel- drive roads, the use of a GPS unit, and a tricky descent into West Coyote Canyon. Four of the plunge pools we found were combined into one sample. We collected numerous large damselfly larvae and crayfish. We observed, but did not collect, several tadpoles. The vegetation was composed of healthy stands of willow, Indian paintbrush, Carex (ellocharius), many assorted grasses, and several cattail.

164 Moonflower Pool, UTWET-85 (moonflwr) Grand County, Utah, Colorado Plateau ecoregion

This wetland depression is located off Kane Creek Road at the end of the Moonflower Campground hiking trail. It is fed by water pouring off the slick rock above this alcove and seeps on the surrounding walls. However, a large portion of the overhanging rock has fallen into the pool, crushing much of the pre-existing hanging gardens. We observed and collected many Dytiscidae Thermonectus marmoletus (predacious diving beetles). Their distinct yellowish spots on their dorsal side were visible from the water’s surface as they swam. Recreationists may affect the pool’s water chemistry by their swimming in the pool during the summer.

166 Hunter Upper Pools, UTWET-86 (hunteru) San Juan County, Utah, Colorado Plateau ecoregion

A short day hike up Hunter Canyon, off Kane Creek Road, leads to this site. We discovered these two pools nestled alongside the north canyon wall. The site is hidden by a thick stand of tamarisk and, thus, is probably not impacted by hikers. Cattail, assorted grasses, Phragmites, and rushes were also present. Many of these are non-native species, which indicate presence and impacts of grazing. The site’s extreme humidity was created by the proximately of so much vegetation and the heat of the afternoon. The invertebrate sample was collected from the two pools and combined. Large damselfly larvae and adult beetles with a brown dorsal side were collected. The water had a blackish tint, indicating decayed organic (plant) matter. The first pool was approximately three to four feet deep and the second approximately five feet deep.

168 Hunter Lower Pools, UTWET-87 (hunterl) San Juan County, Utah, Colorado Plateau ecoregion

This site is located within the campsite area of Hunter Canyon, off Kane Creek Road. The pools are nestled against the south side of the canyon wall and one is under an overhang. Organisms from the two pools were combined as one sample. The invertebrate population initially appeared to be sparse, but upon performing the qualitative picking it turned out to be plentiful. However, the specimens were much smaller than in the upper site. Approximately five-inch long fish were also observed. There was a peculiar film on the water’s surface.

170 Sheep Alcove Pool, UTWET-88 (sheepal) Grand County, Utah, Colorado Plateau ecoregion

This site is located off Highway 128, along the Colorado River, but is hidden by dense growth. To locate this site identify Sheep Canyon on a map and park near the coordinate listed below. It is still a hiking trail but is not marked or maintained. Find it west of Negro Bill Canyon. To get to the pool hike a quarter to a half-mile up this poison ivy filled canyon. Wear protective clothing! Sheep grazed the area in the past, thus the name. Locals, because of the steady 50- degree temperatures and opportunity to cool down on scorching summer days, named it Ice Box Canyon. There are hanging gardens all along and above the alcove pool, dripping water like a shower. The soothing sound of water falling on rock echoes all throughout the alcove. We collected large odonates in the pool and observed crayfish in the stream below. Vegetation observed was composed of grasses, river birch, maidenhair fern on walls, and liverwort and moss on the surrounding rocks. Rare thistle, columbine, primrose, monkey flower, poison ivy, and orchids were also present.

172 Leland Harris Upper Pond, UTWET-89 (lelandup) Juab County, Utah, Great Basin ecoregion

This site is located in the Snake Valley (West Desert) on private property. Permission was obtained prior to sampling from the property owner, Mr. Alred. Because the area is so remote the best way to locate him is through West Desert High School where he is the principal. The wetland complex is south of the town of Partoun and Miller Springs, north of Gandy and Salt Marsh Lake. The water source is the many seeps along the fault line that runs through the Snake Valley floor. The seep that feeds Leland Harris, however, is visible immediately at the western border of the wetland. The site was bordered by saturated soils, had a mud substrate, and an open water center. The area has been grazed before. This pond is one in a larger system. The vegetation was composed of Potentilla, rushes, sedges, small yellow flowers, saltgrass, Salicornia, and greasewood. Rare species of spotted frogs have been found here.

This site is located on the same private property as the upper pond and is located directly southeast of the other site. There was more saltgrass growing here and sedges and grasses dominate the wetland’s periphery. Aquatic vegetation covered approximately one half of the pond’s surface. Although the standing water was more shallow than the upper site, there was a border of thick mud and froth that prevented us from sampling beyond the edges. There was also a small (1 foot diameter), deep depressions off the pond’s edge from which some bugs were collected. Muskrats had dug channels into the pond edges.

This wetland system is fed by two springs, which are visible at the bottom of the pooled area. The sample was collected near the spring source and around the pond edge. The water was deep and crystal clear. The vegetation was composed of Phragmites and various grasses. Many mosquito fish were observed in the pond. They are an introduced species that have become a nuisance. Although they were originally stocked to control mosquito populations, they have out- competed the native fish for their habitat.

178 Kays Creek Pond, UTWET-92 (kaycrkpd) Davis County, Utah, Great Basin ecoregion

This wetland is located on The Nature Conservancy’s Shorelands Preserve property. The site appeared to have been grazed within the past year. The wetland was established where Kays Creek had flooded its banks and flowed to the northwest. Introduced foxtail grew on the periphery of the site. Bulrush, saltgrass, and Phragmites dominated the rest of the site. A flock of ibis was feeding at the wetland when we first arrived. Mollusks dominated the invertebrate sample and several New Zealand mud snails were identified. The botanist observed several beetle larvae, but none were captured in the bug sample.

182 Road Hollow Pond, UTWET-95 (roadhlpd) Summit County, Utah

This site is located in the Uinta NF Mirror Lake Recreation Area, off Whitney Reservoir Road 032 and FS Road 310. This large depressional wetland pond was formed by glacial activity. When we first arrived, an adult moose and her young were grazing at the south end of the site, but moved on after noticing us. The pond size was approximately one acre and was dammed at the north end. The pond’s periphery, where we sampled, was around two to three feet deep, but the water was deeper in the center. Salamanders were observed at the south end, as well. Tadpoles and frogs were present. We collected numerous gold-black stripe headed caddis larvae that have been found at other high altitude sites and found a large leech attached to one of our dogs. The botanist identified sage, willow bushes, many flowers, grasses, and Carex. Pine trees grew on the upland areas.

184 Gold Hill Beaver Ponds, UTWET-96 (goldhlbv) Summit County, Utah

This site is located in the Uinta NF Mirror Lake Recreation Area off FS Road 081. The site consisted of two beaver dam-created wetland ponds. The beaver den, seen in the photo below, was in the lower of the two ponds. The upper pond was the larger of the two and was separated from the lower by a small slope and stream. We heard many frogs singing at the site and observed numerous leeches. The botanist identified Indian paintbrush, delphinium, Carex, willow bushes, thistle, yarrow, rose, and purple aster. There was more plant diversity here than we had observed at other similar wetlands.

186 Gold Hill Pond, UTWET-97 (goldhlpd) Summit County, Utah

Gold Hill Pond is located a quarter mile south of the Beaver Pond site, but was much larger. Although the site was approximately three acres, the deepest spot was only around four feet deep. The invertebrate samples were collected from the south and west shores. Adult damselflies, frogs, and salamanders were present. The bugs were well camouflaged in the dark brown, organic substrate and, therefore, difficult to find. The botanist identified the grasses all along the pond edge. Thick stands of pine encompassed the greater area. The pond was somewhat isolated from roads, but there was one campsite nearby.

188 Whitney Reservoir Road Pond, UTWET-98 (whitrdpd) Summit County, Utah

This pothole system is located in the Uinta N.F. Mirror Lake Recreation Area off Whitney Reservoir Road 032. This wetland is similar to the Mill City Creek Pothole system, but on a much larger scale. They were both glacially formed- a basin/depression with several open water potholes and wetland vegetation in between all surrounded by moraines. Willow shrubs and sedges dominated the vegetation survey. The botanist also identified lily pads and various grasses. An alpine dominated system encompassed the wetland with pine trees, columbine, and sneezeweed (yellow flowers). We collected several of the three to four inch long leeches observed swimming around the lily pads. Tadpoles were also observed.

190 Sims Pothole 2, UTWET-99 (sims3) Uintah County, Utah

We located this pothole at the bottom of a steep sloped moraine off the Sims Peak Road. The open water area was 20 feet long by 10 feet wide and bordered by tall stands of grasses, sedges, standing and fallen pine trees, purple aster, and mushrooms. The pothole appeared to be connected to a larger wetland system that flows and seeps into other potholes during high water seasons. At the east end of the pothole a dry, run-off path was evident. There was some standing water in the grasses at the margins, in addition to the deeper water in the center. A threatening storm was approaching so we had to finish the sample the next day, but it only drizzled.

192 Lily Pad Lake, UTWET-100 (lilypad) Uintah County, Utah

The U.S. Forest Service contact (from the Vernal Ranger District) for this area is Darlene Korner. She led us to several high altitude wetland sites on our Uintah sampling trip. Lily Pad Lake is one of the larger depressional wetlands we sampled at approximately three acres. It is located off Red Cloud Loop Road at the edge of silviculture activities and may experience impacts from recreation as well. There were many lily pads on the water’s surface and grasses and sedges (Carex) growing around the edge. A field of elephant head and purple aster grew on the periphery to the southwest of the lake. Pine trees lined the greater area. Bog-like soils edged the pond. This region was on the margin of glacial activity, and thus may have been formed by glaciers. We observed six-inch long leeches swimming near the pond’s shore and collected a large adult Dytiscidae beetle (2 inches long).

194 Lake Park Pond, UTWET-101 (lakeprk1) Uintah County, Utah

This site is located in the Ashley N.F. on a gated logging road north off Red Cloud Loop and East Reservoir. Silviculture, off-road vehicle activities, and cattle grazing surrounded this wetland system. We called this area a raised bog. There did not appear to be any outlet for the water system and thus it seems that the water sources are run-off and precipitation. This very old site had clay soils and was a “sterile environment”, meaning that there is little to no disruption or recharge, which may result in sterility of this otherwise organic site. The pure, but highly acidic water also supports this idea. This area was not formed by glacial activity (like many of the surrounding sites), but rather hydrostatic soils that pull water to the surface. Chorus frogs were present, but otherwise the site was depaurate- had sparse invertebrate populations. The vegetation was composed of willow shrubs, sedges (Carex), and flowers (including orchids).

196 Lake Park Raised Bog, UTWET- 102 (lakeprk2) Uintah County, Utah

There were several small water pockets (raised bogs) located to the west of the larger wetland site that were sampled separately. Only a few bugs were collected there. The average diameter of the pockets was one foot. Hydrostatic soils created these with the growth of sphagnum moss, which pulls the water pressure up when the moss grows towards the surface. The vegetation was the same with willow shrubs, Carex, and pine trees. To the north of these “bogs” there appeared to be a very old beaver dam, a raised long line of a hump, covered now with grass.

197 Big Park Ponds, UTWET-103 (bigpark2) Uintah County, Utah

Big Park is located in the Ashley NF off Red Cloud Loop on Road 043. The site is a several acre open space pasture, but it’s filled with seeps and springs that make it difficult for livestock to traverse. This fact may prevent the area from being overgrazed during wet periods. However, there were sheep grazing the meadow’s periphery and ATV traffic in the area. Dry rutted areas made it apparent that when dry enough, people had driven ATVs through this meadow. We chose a series of seeps and pools for our sampling site. The deep pools of clear, cold water were connected by seeps that flowed down a slight slope through the meadow. Also, we sampled several steep-sided depressions were you could see about six feet down to a gravel substrate. The depression depths ranged from two to six feet. Our botanist identified sedges (Carex), elephant head, willow shrubs, and shorter meadow vegetation.

199 Summit Park Raised Ponds- UTWET-104 (summitpk) Uintah County, Utah

This site is located in the Ashley N.F. off the Red Cloud Loop and Road 043. We discovered this site by following the old Carter Military Trail that now serves as an ATV trail. Upon first inspection, this area looks like a dry meadow, but when several raised humps in the landscape were examined more closely we found three with water holes on top. Two of them had one-foot diameter openings filled with very cold water. The third was much larger, at approximately 10 feet wide by 20 feet long. We were surprised to collect mayflies and stoneflies here. Grasses covered the meadow and hydrostatic soils formed the hummocks. The underlying soils were clay in composition.

203 Midway Reservoir Pond, UTWET-106 (midwayp) Wasatch County, Utah

This natural depression is located off the Wasatch Mountain State Park road from Midway, but can also be reached by driving up Big Cottonwood Canyon over Guardsman Pass. Off the north side of this road is a small dirt road with a sign for “Midway Reservoir” that leads to the wetland. Bog-like soils border the water’s edge. The vegetation consisted of full bunches of Carex and sedges and aquatic vegetation on the open water. To the north, the site was bordered by thick aspen stands and to the southeast a heavily vegetated slope. There was evidence of skeet shooting in the area; we found many skeet fragments.

205 UM Pothole 1, UTWET-107 (umpot1) Sevier County, Utah

We found numerous potholes (natural depressional basins fed by run-off) to sample that were scattered along the sloped UM Creek valley. All UM Pothole sites are located in the Fishlake N.F. off the road to UM Creek and Sheep Valley. Although Pothole 1 appeared to be in good condition, it was apparent that the area is regularly grazed and frequented by ATV drivers. There were a series of ATV trails that were around the area. The site was approximately one half acre in size with the perimeter saturated with grasses and the center was a small, vegetated open water area. The open water area of this pothole was 1.5 feet at its deepest point with a muddy, organic substrate. Many salamanders were observed. The botanist identified Carex, white flowers (looked like Queen Anne’s Lace), willow shrubs, and aspen trees.

207 UM Pothole 2, UTWET-108 (umpot2) Sevier County, Utah

Pothole 2 was comprised of two open water potholes connected by a shallow channel; water from the upper pothole (foreground in photo) flows into the lower (background in photo) during high water. We found what looked like, tadpole shrimp (Notostraca) carapaces in the sample, but no live specimens. Frogs were heard at the site, but not observed. The botanist identified willow bushes, ribes (golden currant), and grasses that surrounded the wetland. An aspen grove and conifers encompassed the overall site. As seen in the photo, many downed trees had fallen into and spanned the potholes. A thunderstorm interrupted our sampling effort.

209 UM Pothole 3, UTWET-109 (umpot3) Sevier County, Utah

Pothole 3 was the highest in elevation of the sites in the UM valley and the most impacted by cattle grazing. It was an approximately 1.5 acre meadow. Of the four potholes only two had water in them. The east, drier side was more grazed and pock marked by cattle than the west, more wet and muddy side. The botanist identified the Carex and grasses that dominated the site.

211 UM Pothole 4, UTWET-110 (umpot4) Sevier County, Utah

Pothole 4 was the farthest down the valley and the most secluded of the wetlands sampled, lying at the bottom of a steep moraine and nestled in an aspen grove. There were three dry potholes nearby that must all flow together during high water. Here we did find two live tadpole shrimp (Notostraca), verifying our suspicion that they had been present in the upper potholes. The botanist identified willow shrubs and grasses. Aspen and conifers grew on the upland.

213 Mill City Creek Pothole, UTWET-111 (millcty2) Summit County, Utah

This site is located in the Uinta N.F. Mirror Lake Recreation Area, off Whitney Reservoir Road 032. The wetland is a glacially formed depression containing four open water pools. The sample material was gathered from these and sorted as one sample. The site was formed by the geographical influences of a gentle slope to the east that directs water into the depression and the moraine that creates the western barrier. The botanist identified grasses and willow bushes in the depression and conifers on the upland area. Frogs were observed at the site. Sheep grazing and recreation may have impacts here.

215 Scad Valley Beaver Pond, UTWET-112 (scadvly) Sanpete/Emery County, Utah

This remote, high altitude valley straddles Sanpete and Emery counties. At first, it appeared that we would only find dry, slope wetlands in the valley. We discovered this old beaver dammed pond after driving to the highest vantage point in the valley and scanning the land below. It sits atop a small plateau, not visible from the road, on the west side of the valley. The open water pond was approximately one acre in size and three to four feet deep. Salamanders were observed. There were many logs with beaver teeth markings embedded in the east bank (downslope side), leading us to believe it is an old beaver dam. There was some erosion of this bank. On the west (upslope) side were several rivulets/seeps that fed the pond. The botanist identified grasses and Carex at the pond edge, sage and gentian on the upland areas.

217 Miller Flat Road Pothole, UTWET-113 (millerflt) Sanpete/Emery County, Utah

We discovered this wetland pothole on a dirt road off the Miller Flat Road. There were several other potholes in the area, but none had sufficient water to collect an invertebrate sample. This one, however, had some standing water. Approximately 90% of the pothole was covered with grass, surrounded by willow shrubs, and next to stands of aspen and conifer. Recreation and grazing are potential impacts.

219 Boulder Mountain Pothole 1, UTWET-114 (boulder1) Wayne County, Utah

This pothole is located in the Dixie N.F. on the Boulder Mountain top near Crater and Crescent Lakes. This site is at the highest altitude of any wetlands sampled, so it was fairly unique. The water was only about one to two feet deep and large volcanic rocks were scattered throughout the depression. The surrounding area was tundra-like with hardy, short grasses, scattered, pine covered knolls, and shrubby bushes. Cattle and sheep graze this area. Marmots were observed at the site.

220 Boulder Mountain Pothole 2, UTWET-115 (boulder2) Wayne County, Utah

This pothole is also located in the Dixie N.F. on the top of Boulder Mountain and at a high elevation. The vegetation was sparse with short grasses, yellow flowers, and conifers on the upland knolls. There were volcanic rocks at this site also, but not as many as in Pothole 1. There were many small rocks in the soil though. Lots of algae were growing in the pothole. The water was not of constant depth. It was much deeper in the center than the periphery where we sampled. Cattle and sheep also graze in this area. When we first arrived, we heard a coyote yelping to the east of where we sampled.

221 Cook Pothole Upper, UTWET-116 (cookphup) Wayne County, Utah

Both the upper and lower potholes are located in the Dixie N.F. off the road to Boulder Mountain Top and north of the main Cook Lake. It appeared that the upper site flows into the lower during high water. The site contained several different habitat types: wet meadow, pond, and tall grass marsh. A steep scree field and stand of conifers bordered the site to the east. The botanist identified various grasses, conifers, Carex, and asters. Salamanders were observed. Grazing and recreation may impact the area.
