Summary of 2011 Erythronium study

RARE ERYTHRONIUM SPECIES ON GREEN DIAMOND RESOURCE COMPANY (GDRCO) PROPERTY: ADDRESSING PROBLEMATIC CHARACTERISTICS PRESENT IN NORTHWESTERN CALIFORNIA POPULATIONS

SANVILLE, C., HAYASHI, B. Green Diamond Resource Company, PO Box 68, Korbel, CA 95550

Abstract for talk given at the January 2012 CNPS conference:

Two Erythronium (fawn lily) species encountered on GDRCo property with a California Rare Plant Rank (RPR) of 2.2 are Erythronium revolutum and E. oregonum. Although some populations exhibit diagnostic characteristics, others exhibit traits intermediate between the species and/or between the endemic but not rare E. californicum. While E. oregonum has white tepals, tendency towards albinism in E. revolutum becomes more pronounced toward the south end of the range in coastal northern California (Applegate, 1935). There are few element occurrences (EOs) of E. oregonum rated as good or better in the California Natural Diversity Database (CNDDB) however E. revolutum is close to the threshold for status review. Protection measures will no longer be required if the RPR is adjusted downward. Because of the difficult nature of making a conclusive identification, it is likely that some of the occurrences of E. revolutum are E. oregonum. There are overlapping EOs of both species and considerable uncertainty regarding identification. The identity of these species needs to be resolved prior to a status review. GDRCo botanists collected flower and leaf samples from seventeen Erythronium populations in 2011. Flowers were disassembled and used to conduct a morphometric analysis focused on diagnostic characters, following methods used by others investigating Erythronium species. Leaf samples were dried in silica and will be used in a complimentary genetic analysis. The authors hope this initial investigation garners interest by others familiar with these species and a collaborative effort can be made to assess all known populations in California.

All known populations of Erythronium species present on GDRCo property were summarized and reviewed as potential collection sites. Sites were chosen based on population size of mature individuals to minimize impact. No more than 20% of flowering individuals were considered eligible for collection at any one site. During the spring of 2011, 15 flowers and 30 leaf tissue samples per population were collected at 17 sites (see Map on page 7). 15 of the 30 leaf tissue samples came from the same plants from which the flowers were collected. Collections were made from individuals spaced at least 1 m apart. Flowers were disassembled and taped onto index cards for later morphometric measurements. Color values were measured using fresh material and values were taken using Munsell color charts for plant tissues. A total of 30 morphological characters were recorded for each flower. Leaf tissue samples were preserved in silica gel for later genetic analysis. The methods employed in this study closely follow those used by Dr. Geraldine Allen in her work on Erythronium species in the Pacific Northwest.

Based upon the morphological features observed in the field, the 17 sites were assigned to the following taxonomic groups. The objective of this study is to determine whether or not these taxonomic assignments are correct.

Map of Erythronium study area

West Inc. conducted a hierarchical agglomerative cluster analysis, using Ward’s method as the similarity index. Critical value for distance (Euclidean) between clusters was calculated. The suggested number of clusters was calculated based on this critical value. All analyses were conducted in R. The most diagnostic characters are those that are used to separate the species in dichotomous keys; tepal color, stigma length, filament width, anther length and anther color. The graphs below illustrate the results when only the most diagnostic variables were included in the analysis and when all of the morphological characters were included. There was considerable taxonomic overlap between clusters which indicates that the genetic analysis will be absolutely necessary to definitively assign sites to taxonomic groups. It appears that more than one site contains individuals of hybrid origin.

West Inc. also conducted a Principal Components Analysis (PCA) using all of morphometric variables as well as a subset of the most diagnostic characters; tepal color, stigma length, filament width, anther length and anther color and tepal length and width. The graph below plots the individual flower scores on the first two axes (29.75 + 20.56 = 50.31% of the variance) at each of the 17 sites when the subset of variables was used in the analysis. The first two axes are both driven primarily by tepal color, filament width, stigma length and anther color. These results are relatively consistent with the taxonomic groups we assigned to sites in the field. Erythronium revolutum (green symbols) group together relatively well, with a subset that groups tightly with E. oregonum ssp. leucandrum. Erythronium oregonum flowers are split between the E revolutum and E. oregonum ssp. leucandrum groups. Erythronium californicum forms a diffuse group with the most southern of the three sites removed from the other two sites. The flowers from the E. citrinum v. citrinum site are tightly clustered and place very closely to E. californicum. Morphological features observed on these flowers were often consistent with E. californicum suggesting this site may be a hybrid with a E. californicum parent. Flowers from site 15 clearly exhibited traits intermediate between E. revolutum and E. californicum and these flowers placed in all three of the main clusters. At this point we are pursuing collaboration with Dr. Geraldine Allen to compare our data with pure populations of E. oregonum and E. revolutum and ultimately we will need to procure funding to conduct the genetic analysis on our leaf samples to resolve this issue.

Coastal Lagoons and Little River Botanical Management Plan (BMP) 2011 Status Report

On 8 July, 2008 DFG signed the Coastal Lagoons and Little River Botanical Management Plan (BMP) and recommended that the ‘Specific Proposal for the 2008 Field Season’ be implemented as described in Section 8.0 of the document. About the same time Lycopodium clavatum (running pine) was moved from CNPS list 2.3 to list 4.1. Under the implementation phase in 2008, there was a transition from 100% of the projects in the Coastal Lagoons and Little River Botanical Management Area (BMA) receiving full floristic surveys conducted by botanical technicians, to 50% receiving full floristic surveys and the other 50% receiving only surveys focused on detecting L. clavatum and unique botanical habitats (e.g. sphagnum bogs, well developed lakes or ponds, coastal prairie or large mossy boulders or rock outcrops). These focused surveys were conducted by Registered Professional Foresters (RPFs). On 9 February, 2009 DFG concurred with the long-term survey protocol for THPs within the Coastal Lagoons and Little River BMA as proposed by GDRCo. The new language replaced BMP section 8.0 “Proposal for 2008 Field Season”, pages 18 and 19, and the new Section 8.0 was appended to the BMP. The measures contained within were implemented during the 2009 field season and will remain in effect indefinitely. From the 2009 field season forward, RPFs shall conduct focused surveys for 100% of the THPs within the Coastal Lagoons and Little River BMA. The new language is enclosed below for reference.

GDRCo and DFG agreed that the long-term survey protocol for THPs within the Coastal Lagoons and Little River BMA, effective 2009, is as follows: 1. RPFs shall conduct focused surveys for all THPs within the Coastal Lagoons and Little River BMA. RPFs shall be responsible for reporting the presence of any unique, high quality, sensitive plant habitat within their project area, e.g. bogs, well developed lakes or ponds, coastal prairie or large mossy boulders or rock outcrops. When Lycopodium clavatum is encountered within THP areas voluntary, non-enforceable PPMs will be applied. These PPMs include establishing ELZs for select populations and retaining non- merchantable trees. If other sensitive species are observed, the RPF will consult with GDRCo botany staff. 2. Botanical technicians shall survey unique, high quality sensitive plant habitats within THPs as identified by RPFs. If sensitive species are discovered appropriate PPMs shall be applied. 3. Botanical technicians shall monitor a subset of L. clavatum populations on a yearly basis. Initially, monitoring activities will focus on pre and post-harvest monitoring of populations protected with voluntary, internal PPMs that were implemented for plans submitted after July 8, 2008. Revisions to internal PPMs may be made based on monitoring results. 4. Botanical technicians will survey unique or high quality habitats outside of THPs when they are identified. The intent is to find and survey areas within the BMA that have the greatest likelihood of supporting sensitive species, regardless of whether or not the habitat would ever be impacted by timber harvest operations.

In 2011, thirteen new patches (BotID#s) of running pine were documented in THPs within the Coastal Lagoons and Little River BMA. Ten of those were protected within ELZs wherein only merchantable trees were removed. The internal protection measures for running pine were implemented in 10 of the 18 THPs reviewed in the Coastal Lagoons and Little River BMA in 2011. The detection rate of running pine within the BMA by foresters is consistent with what botanical technicians have found in the past.

Howell’s Montia, Montia howellii (CRPR 2.2) Salmon Creek Monitoring Report

In 2001 about 17 miles of road in the Salmon Creek tract were surveyed for the presence of Montia howellii in partial fulfillment of required THP related surveys. Surveyors discovered a very large and well-distributed population of these minute, annual plants throughout the mainline Salmon Creek road system. Populations encountered were quantified, mapped and given an identification letter for tracking purposes that later became a BotID#. Thirty-five individual groups were identified that year. During the spring of 2002-2004, four of these populations were monitored using systematic hand counts and/or extrapolation plots to document abundance trends over time. Overall, the populations monitored appeared to remain stable to increasing although there were extreme year-to-year fluctuations. The 2001-2004 monitoring results are summarized below. Monitoring 2001 2002 2003 2004 Point (Estimates) B ~10,000-20,000 16,453 19,466 3,720* E ~100 7,236 4,509 22,862 L1 ~30 981 403 1,167 P ~200 249* 1,332 2,749 Yearly Total ~10,330-20,330 24,919 25,710 30,498 *MOHO total (B, 2004 & P, 2002) might be under represented because counts were conducted late in the season when plants were already senescing and it is likely that some plants were no longer detectable.

The Salmon Creek road system was managed under the Salmon Creek Watershed Management Plan (SCWMP) since 1993. The plan considered watershed specific physical characteristics, past activities and future forest management objectives while specifying measures designed to mitigate or avoid significant impacts to fisheries, aquatic habitat and wildlife. The primary objective was to reduce sediment production, transport and deposition into watercourses while maintaining these dirt roads for seasonal use. The erosive soils in this watershed are derived from the Wildcat Group, which produces fine grained clays and silts that can easily be mobilized. To manage soil transport during the rainy season, waterbars and other diversion features were installed prior to the onset of rain, roads were closed to vehicles during the rainy season, and roads were graded for use again at the beginning of the dry season. This annual management cycle was complimentary with the annual life cycle of montia. The berms closing off temporary roads, roadside ditches and consistent placement of water bars created depressions where water, sediment and seeds accumulated resulting in dense patches of montia. Road closures during the plant’s growing period, (Jan-May) allowed seeds to germinate and plants to mature without significant disturbance. The annual grading likely helped to distribute seeds, and more importantly, prevented competing vegetation from growing on the road surface. The fact that a very robust population of montia was discovered throughout the mainline road system several years into this management plan is evidence that the management cycle was compatible with the persistence of montia.

Montia has been found most abundantly in areas of compacted, poorly drained soils with accumulation of fine sediments. Low areas of the road that were seasonally inundated, shady moist roadsides, the base of the upslope side of waterbars and other microtopographic features along the road prism that remained mesic through the spring were the preferred habitat for M. howellii in this road system. Unfortunately, many of these features are associated with road impairments that have the potential to deliver sediment. The persistent and necessary use of quads (as an alternative to vehicles which were not permitted) on these dirt roads during the winter months led to reduced functionality and/or failure of sediment control 11 features, such as the compaction or breaching of waterbars. The entire basin is in the fog zone and intense vehicular use, log hauling, and heavy equipment use during periods of persistent summer fog also compromised sediment control efforts during the dry season.

As GDRCo was looking to develop Timber Harvest Plans (THPs) in the Elk River watershed, which was listed as impaired by sediment in 1998, it became apparent that in order to obtain a WDR permit from the Water Quality Control Board, the management plan for Salmon Creek needed to be revised to more intensively manage sediment. It also made sense to adopt the same management practices for GDRCo property in the Elk River watershed since both areas are accessed via the same road system. These efforts resulted in the South Fork Elk River Management Plan and the Sediment Reduction Plan for Existing Roads – Salmon Creek Watershed, both produced in 2006. The implementation phase of these plans began during the summer of 2006.

Since several of the management activities associated with these plans had the potential for adversely impacting M. howellii, particularly surface rocking of road sections occupied by plants, the entire area surveyed in 2001 was resurveyed in 2006 in order to document the distribution and abundance of plants prior to the initiation of these activities. The area of the survey closely corresponds with the series of road work points outlined in section II of the S-2650 (14-0503) 1-06-012H THP (See Table 1). The census of montia along these 17 miles of road was reproduced in 2007 and 2008 after road work had commenced.

Comparing the total number of plants counted (and estimated) in 2001 to those found in the same locations in 2006, it appears as if there was a significant decline. In 2001 the most conservative total number of plants found was 25,534 and in 2006 this number had decreased to 10,832. This is quite notable given the upward trend detected across the four sampling areas from 2001-2004. The overall decline is likely even more significant because the four monitoring areas contained far more plants in subsequent years than was estimated in 2001, making the disparity between previous years and 2006 even more extreme. Population “E” or BotID#1091 alone was estimated to contain 22,862 plants in 2004. However, there was an area that did not contain plants in 2001, and 4,000 plants were estimated to occur at that location in 2006. It is possible that the populations had migrated considerably throughout the road system and the total number of plants in the watershed had remained relatively stable. Anecdotally, at the end of the 2008 field season, 46 total BotID#s were documented on the Salmon Creek road system and nine of these were newly detected in 2008. These “new” populations were found between previously documented populations or on old spur roads off of the main roads surveyed.

The data from 2001 and 2006 give a very rough sense of year to year fluctuations in distribution and abundance of plants under the old road management plan. The data from 2007 and 2008 give some indication of how the population has responded to the major road improvement activities, e.g. surface rocking, installation of new culverts and mulching and seeding disturbed ground (See Table 2). In 2006, 50% fewer plants were counted along the same roads surveyed in 2001. In 2007, plant numbers increased 45% and in 2008 decreased 59%. The timing of the road work was such that it was expected to have the greatest adverse impact on plant numbers in 2008 and a lesser impact in 2007, as was observed. When the average number of plants present prior to the initiation of road work (2001 and 2006 data) is compared to the average number of plants after the road work had commenced (2007 and 2008 data) there was a 23% decline. A decline of 20% or more between 2006 and 2007 was the threshold presented in 2006 to determine whether or not the population was experiencing a significant downward trend. Since the road work was expected to have more of an impact on 2008 numbers, an evaluation of the population trend was delayed. Surveyors have observed that rocking and mulching have diminished habitat in previously occupied areas and plants are typically restricted to persistently wet areas of bare dirt at the road margins and pullouts. While road improvement activities have clearly impacted plant numbers and available habitat, the year to year fluctuation has been so great it is difficult to discern the magnitude of the management impact.

The census approach used to monitor plants in this road system lead to the creation of both large and small populations with arbitrary boundaries that were difficult to track from year to year. Some populations (BotIDs) were contained within a very small section of road while others were along long sections of road (>1.3 miles long) and they were difficult to reliably relocate year to year. Since populations can migrate and annual plant numbers fluctuate wildly, it has been difficult to decide when to call a group of plants a “new” population and when to lump it with a population found previously. This approach relied on visiting and counting plants along the entire road system yearly in order to compare years and attempt to determine gross trends. The variation in the precision of estimates and actual counts between surveyors and years also made it difficult to make any conclusions about trends. Even though the number of plants seems to have fluctuated ~50% between years, our data does not conclusively indicate whether or not the population as a whole is stable, increasing or decreasing over time.

A robust, plot-based sampling strategy that could reliably capture long-term trends and correlate abundance with management driven environmental variables was needed. With the acquisition of LiDAR data, GDRCo began the process of realigning the GIS road layer. Linear referencing was not complete until 2010, so in 2009 GDRCo experimented with a new approach that entailed sampling a set of road segments of equal size while also trying to check on the status of known populations. That year, eighteen (¼ mile) sections of road were monitored. The road segments were subjectively created in GIS using the centroids of known BotIDs and measured 201 m on either side of the centroid. This created segments that were 402 m long, equal to ¼ mile. Before the segments were created, 18 of the 46 BotIDs were randomly selected using a random number table to determine which areas would be sampled in 2009. Numbers of plants were estimated when they could not be counted quickly. The data are provided in Table 3, but since the entire area occupied by the population (BotID) in 2008 may not have been included in the road segment sampled in 2009, it is not possible to determine if there were truly more or less plants in 2009. In most cases it looks likely that there were fewer plants in 2009. Valuable information was gathered from the 2009 survey that was useful in designing the long-term monitoring strategy that was implemented in 2011.

Long-term Monitoring Strategy for montia in Salmon Creek as implemented in 2011

Objectives: 1. Determine if the population of Montia howellii (MOHO) growing along the mainline Salmon Creek road system is increasing, decreasing or stable over time. Our metric will be number of plants per linear measurement.

2. Determine if presence or absence, or density of MOHO are correlated with habitat/management variables. 1. Percent cover of road surface type in five categories measured at the quadrat level: a. Rock b. Mostly rock with some fines c. ½ Rock, ½ Fines d. Mostly fines with some rock e. Fines (dirt, clay, sand) Observations over the last ten years and studies conducted by PALCO show that high quality habitat is compacted natural surfaced roads with high clay content. Rocking of roads leads to plant decline or extirpation. Over time rocked roads become suitable habitat again. 2. Percent cover of competing vegetation measured at the quadrat level – we will measure cover of plants at ground level other than MOHO, including straw mulch or logging slash when they are at densities that clearly prevent plants from growing 3. Solar insolation at the 50 foot road segment level – Hemispherical photography (may not do)

3. If the population shows a trend of significant decline, as evidenced by either a significant abrupt change in one or two years, or a significant long-term trend over several years, consult with DFG and attempt to coordinate road management activities with activities designed to maintain MOHO (e.g. if abundance is highly correlated with specific habitat variables then manage for more of those).

Sampling Plan: 1. The sampling universe includes the GDRCo Salmon Creek tract mainline road system on the north side of Salmon Creek, with the exception of one road that crosses to the south side of Salmon Creek. That road is included until it reaches the GDRCo property line. The roads that are classified as mainline roads for the purpose of this study are the main roads that are projected to be used and maintained over the next ten years. For the most part the roads included provide an access loop through the extent of the property on the north side of Salmon Creek. The significance of this continuity is that it should allow us to account for plants anywhere they may have migrated along the mainline. The majority of the mature timber in this tract has already been harvested and the main area left to harvest is at the northeastern portion of the sampling universe. The mainline road accessing this area has been reconstructed and newly constructed in recent years and while MOHO has not been found on this road yet, it does contain potential habitat. There are other roads included that to date have not supported MOHO, as well as roads that have supported large numbers of MOHO until they were rocked a few years ago. Some of roads included may get more or less use than others over the course of the study. The sampling universe contains roads with both natural and rocked surfaces. Additional rocking may occur in the years to come. We anticipate that the habitat quality along roads or portions thereof will fluctuate throughout the course of the study.

2. The roads in the sampling universe were designated as routes with beginning and end points and then routes were ordered in space and divided into 50 foot segments that will serve as sample plots, that each have a unique segment ID (SID). The width of the road varies and plants are often found at the margins and in the middle, so the plots will not have a fixed dimension across the 18

width of the road. Our data will reflect plants per linear foot rather than per square foot. Each 50 foot segment was given a permanent route ID and segment ID with fixed start/stop UTM coordinates that can be loaded into GPS units. *There are three road segments that are shorter than 50 feet, but longer than 25 feet so we will keep them. There are 1551 road segments total.

3. Stage 1 consists of determining presence or absence of MOHO in the sample plots or road segments (SID). We will draw a generalized tessellation stratified (GRTS) sample of 50-foot road segments to ensure sample plots are spatially balanced (interspersed) throughout the population with few if any adjacent to one another. The GRTS sample will consist of a specially randomized list of road segments that preserves spatial balance in adjacent sets of segments. The first 110 segments on this list will be placed in a group called Panel 1. Each subsequent group of 20 segments will be placed in panels numbered 2 through 73. Road segments in Panel 1 will be sampled every year during the study. Road segments in panels 2 through 73 will be sampled twice every 5 years on a rotating basis. During the first 5 years of the study, a total of n = 130 sites will be sampled (Panel 1 plus one of Panel 2 through 6). After year 5 of the study, a total of n = 150 segments will be sampled (Panel 1 plus a previously unvisited panel plus a previously visited panel). Preserve this text to keep track of where we got n=150: We need to decide what percentage of the total 1551 frequency plots will be sampled each year. The absolute maximum it seems feasible to do is 150 (10%). That may end up being too many but we can try if it seems necessary to sample 10%. In normal years there is about a three+ week window in March that is appropriate for this monitoring. Plants are mature and have not senesced to the point of making detection difficult. Conditions are variable across the sampling universe due to exposure. Access to the plots is by quad only, which is an additional constraint. In 2011 it took 38 crew days over the course of three weeks, so in 2012 with only two crews of two (rather than three crews of two as in 2011) it is estimated to take 4 weeks.

4. Stage 2 consists of determining patch size in the selected sample plots. Each sampled plot will be divided into 25 2-foot quadrats that extend across the entire width of the road. Presence or absence of MOHO will be recorded for each of the 25 quadrats in the sampled plot. To estimate probability of detecting MOHO assuming it is there, two surveyors will make independent presence/absence observations and record their data separately. Boundaries of the quadrats will be delineated using stakes/spikes at two foot intervals at both edges of the plot (outside road margins) and then using string (hip chain) to create a grid. See the diagram below. Road Margin

Road Margin

Start tying string around the spikes here and following a path like the arrows indicate, connect the spikes until you th have completed the grid at the 25 quadrat. If you have two hip chains the other person can start at the opposite end.

5. Stage 3 provides an estimate of abundance. If MOHO is not detected on any quadrat, sampling at the segment is complete. If MOHO is detected, two of the occupied quadrats will be randomly selected and the number of MOHO plants will be counted in those quadrats. If MOHO is present in only one quadrat then that quadrat will be sampled. 19

6. Within each of the randomly selected, occupied quadrats and one randomly selected, unoccupied quadrat, two environmental variables will be measured; % cover of competing vegetation and % cover of road surface type. The other variable of interest is microsite moisture as a result of shade and surface topography. Measuring solar insolation with hemispherical photography seems to be the most precise way to get at this variable. We estimate it would take a week of one person’s time to take the images and process them. We did not measure this variable in 2011. We would like to be able to do it after 1 June when it is possible to drive vehicles on the roads. The concern is that leaf out may be greater at that time than when the plants were actively growing and reproducing. We could do a GIS analysis of slope and topographic shading if we decide that is necessary or a reasonable surrogate.

The field methods are described fully in the sampling procedures and will not be duplicated here.

2011 Preliminary Findings: Between 3/1/11 and 4/2/11, 130 (8.38%) plots of the 1551 total plots (SIDs) in the sampling universe were sampled (see Map on page 21). This included the 110 permanent plots in ‘Panel 1’ and 20 rotating plots in ‘Panel 2’. Plot start points were located in the field using handheld GPS units. All plots were monumented with blue metal tree tags on both sides of the road at the plot start with the plot number (SID) imprinted on them. PVC stakes and pink pin flags were placed on both sides of the road exactly at the plot start, since the tree tag placement was dependent on the availability of a tree or stump which was not always present exactly at the plot start. MOHO was present in 56 (43%) of the plots and absent in 74 (57%) of the plots sampled in 2011. Each plot contains 25 quadrats, so there was a total of 3250 quadrats sampled across the 130 plots. Of those, 464 (14.3%) were occupied by MOHO. Within plots, 0-25 quadrats were occupied (see Chart 1). Up to two quadrats per plot occupied by MOHO were randomly selected for MOHO counts and 600 MOHO plants were counted across 102 quadrats. A total of 0-79 plants were found in each of the 102 quadrats, with an average of 5.88 plants per quadrat and a median of 2. There are 38,775 quadrats in the sampling universe (1551 plots with 25 quadrats each). If we assume 14.3% of them are occupied that would be 5545 occupied quadrats. If we assume they each contain 5.88 plants then that would be 32,605 plants in the whole road system, which is very close to the 2001 estimate and much higher than was found in 2006-2008. If we use the median number of plants instead, then that would calculate to 11,090 plants in the sampling universe which is more in line with the 2008 estimate and a continuing downward trend. However, since this is an entirely new sampling approach it is not appropriate to compare to previous years data. It will take several years of data Chart 1: Distribution of the 130 plots collected under this sampling protocol to have the power to detect trends. In 2012, sampled in 2011 by number of the 110 permanent plots are being sampled quadrats occupied by MOHO as well as 20 rotating plots in ‘Panel 3’. 80 Since there are fewer seasonal technicians 70 in 2012, the sampling will take longer and it is hoped that they will have time to 60
