Introduction

From 2005-2008, the National Park Service funded several research projects to document the vascular plant flora and distribution of selected rare plant species in Cedar Breaks National Monument (Fertig 2009a, Fertig et al. 2009, Fertig and Reynolds 2007, 2009). In 2009, some carry-over funds were available to continue this work. Studies in 2009 focused on three specific objectives:

1. Confirmation of the presence of Zion draba (Draba asprella var. zionensis) in Ashdown Canyon;

2. Additional surveys for new vascular plant species in the Ashdown Canyon region of Cedar Breaks National Monument;

3. Compilation of a vascular plant checklist for the Ashdown Gorge Wilderness Area of Dixie National Forest, located immediately north and west of Cedar Breaks Na- tional Monument (and recently proposed for potential annexation by the National Park Service if Cedar Breaks were to be changed legislatively from a national monument to a national park).

The following report summarizes findings from the 2009 field season. It contains up- dated information on the status of Zion draba, a revised statistical summary of the flora of Cedar Breaks National Monument, an annotated checklist of the flora of Ashdown Gorge Wilderness Area, and a comparison of the floristic composition of the wilderness and the monument.

Methods

During the summer of 2009, I made two trips into the bottom of the Ashdown Gorge portion of Cedar Breaks National Monument (25 June and 18 August) to survey potential habitat of Zion draba and search White fir forest and wetland sites for potential new species for the monument flora. I made four additional trips into the Ashdown Gorge Wilderness Area from 24 June to 18 August 2009 to document the local flora and build upon a preliminary checklist I started developing in 2006. Survey sites and routes (Figures 1, 2) were selected to encompass the full array of major vegetation types and geologic substrates exposed within the wilderness area.

Nearly all new species encountered in the monument or the wilderness area during 2009 were either photographed (if populations were too small for sampling) or collected for voucher specimens. Collections from the monument will be deposited in the Cedar Breaks National Monument herbarium (housed at Zion National Park), while those from the wilderness area will be deposited at Brigham Young University. Addi- tional information was recorded on habitat, abundance, and location within the study area for each species.

The final checklist for the Ashdown Gorge Wilderness Area (Appendix A) was annotated to include supplemental information on synonyms, life form, geographic range (within the context of Utah), native status, data source (collector and collection number or observation data), year of earliest documentation, and other comments of inter- est.

Results and Discussion

Search for Zion draba

Zion draba is a narrow endemic of the White Cliffs, Zion Canyon, Kolob Plateau, and Camp Creek areas of Washington, Kane, and Iron counties, Utah. The majority of all known populations of this species are found in Zion National Park, Grand Staircase- Escalante National Monument, and BLM lands. Most populations occur on Navajo Sandstone cliffs and canyons in Ponderosa pine and Two-needle pinyon/Utah juniper communities at elevations of 3450-8530 feet. Zion draba has also been reported from the Deep Creek Mountains of Juab County, Utah (Holmgren et al. 2005; Welsh et al. 2003), but these reports are now believed to be erroneous (Welsh et al. 2008). Draba asprella var. zionensis is included in the documented flora of Cedar Breaks Na- tional Monument (Fertig 2009a) based on a 1977 collection in the CEBR herbarium (Dickman s.n.) that has been corroborated by two authorities. Unfortunately, the label of the Dickman collection does not include any specific locality information other than “Cedar Breaks National Monument”, nor does it contain any habitat data. The report for Cedar Breaks is unusual in that the typical Navajo Sandstone habitat of this species is not present in the monument.

During 2007 and 2008, Doug Reynolds and I conducted a survey of the Cedar Breaks area for Zion draba and 17 other globally rare and locally endemic vascular plant species (Fertig and Reynolds 2007, 2009). These surveys were conducted primarily on outcrops of the reddish-orange and white Claron limestone, but also included exposures of the Straight Cliffs, Wahweap, and Brian Head formations. All of the target species were relocated during this survey except for Zion draba. Fertig and Reynolds (2009) reported that potential habitat might still be present for this species on white chalky sandstone cliffs of the Wahweap Formation near The Quarry along Rattle Creek and on other tributaries of Ashdown Creek. These areas were surveyed late in the summer of 2008, after Draba asprella var. zionensis is typically in flower, and thus populations could have been missed had they been present. On 25 June, 2009, I revisited The Quarry area with monument superintendent Paul Roelandt and Dr. Fred Govedich of Southern Utah University. We climbed the white cliffs of The Quarry to explore a series of springs and hanging gardens, as well as bare cliff exposures. The sandstone in the area was observed to be very crumbly and of a higher clay content than is typical of Navajo Sandstone. No populations of Zion draba were observed in this habitat. I returned to the area on 18 August, 2009, to explore the Spring Creek drainage on the north side of Ashdown Gorge. This area also has exposures of Wahweap Sandstone as well as the Straight Cliffs formation. A small population of Breaks draba (Draba subalpina) was found on siltstone outcrops and steep, S-facing slopes in the area, but no oc- currences of D. asprella var. zionensis. After three years of searching within Cedar Breaks National Monument and adjacent areas of the Ashdown Gorge Wilderness and Dixie National Forest, Dickman’s population of Zion draba has still not been relocated. Extensive areas remain unsurveyed within the Cedar Breaks area, so this species might still await rediscovery. Another possibility is that the Dickman specimen was actually made in Zion National Park (where Dickman also made collections in the 1970s) but was inadvertently mis-labeled as coming from Cedar Breaks. For now, the species should probably remain on the Ce- dar Breaks National Monument species checklist, but with the note that it has not been relocated in recent years and might be erroneous.

Updates to Cedar Breaks National Monument Flora

Surveys in 2009 resulted in the discovery of 11 new vascular plant species for Cedar Breaks National Monument (Tables 1, 2), increasing the total number of species confirmed or reliably reported for the monument from 354 to 365 (an increase of 3%). The new discoveries include one new vascular plant family (Ophioglossaceae), increasing the number of documented families to 57 (Table 1). Six of the newly documented species had previously been identified as potential members of the flora (Fertig 2009a, Appendix B), but had not yet been documented within the monument. Eight of the new species were discovered during surveys of wetland sites in the bottom of Ashdown Gorge, two were discovered along the rim of the Cedar Breaks Amphitheater, and one

was found while establishing upland monitoring plots for the Northern Colorado Pla- teau Network (Sarah Topp’s discovery of Stellaria umbellata).

The most notable discovery in 2009 was documentation of Moonwort (Botrychium lunaria) along the amphitheater rim, just south of the Rattlesnake Trail. I found Moonwort on 13 August growing among orangish-red Claron limestone talus in a cushion plant community with several rare plant species, including Peterson’s campion (Silene petersonii), Podunk groundsel (Senecio malmstenii), and Least spring-parsley (Cymopterus minimus). Previously, Doug Reynolds and I had surveyed this area on several occasions, but we had not detected the diminutive fern. Only one individual was observed at the site (Figure 4) . Due to its small population size, I documented the occurrence with photos rather than collecting a voucher. Botrychium lunaria is cate- gorized as “Infrequent” by the Utah Conservation Data Center and ranked S1 (extremely rare) within Utah, despite a relatively broad distribution in the mountain- ous portions of the state (Utah Division of Wildlife Resources 1998). Many related Bot- rychium taxa are considered species of concern as they are rarely observed because of their small size and ability to persist underground for two or more years. Significant areas of potential habitat exist for Moonwort along the Cedar Breaks Amphitheater rim, particularly in areas that may have small seeps near the surface (as at this site and others along the north and eastern rim).

The ten other new species documented in 2009 all occur widely across Utah and western North America. Bull thistle (Cirsium vulgare) and Prickly lettuce (Lactuca serriola) are introduced species, bringing the total number of exotic plant taxa in Cedar Breaks National Monument to 20 (Table 1). Neither species is classified as Noxious in the state of Utah.

In addition to new species discoveries in 2009, one historical species was relocated at Cedar Breaks. Bill Gray found a population of Twincrest onion (Allium bisceptrum) near the monument campground/picnic area in July 2009. This species had not been recorded in Cedar Breaks National Monument since 1947 (Fertig 2009a).

Flora of Ashdown Gorge Wilderness Area

The Ashdown Gorge Wilderness Area is located due north and west of Cedar Breaks National Monument (Figure 1). The wilderness was officially designated by Congress in 1984 and is presently managed by Dixie National Forest. In 2006, the Iron County Commission proposed congressional action that would expand Cedar Breaks National Monument to include the Ashdown Gorge Wilderness and private inholdings, with the entire area being renamed Cedar Breaks National Park. As of 2009, no legislation has been passed by Congress to make the proposal a reality.

The north and south ends of the Ashdown Gorge Wilderness include extensions of the Cedar Breaks Amphitheater rim and colorful badland outcrops of the Claron Forma- tion. An extensive area of Bristlecone pine (Pinus longaeva) woodland and cushion plant communities occur in the Twisted Forest along the north boundary of the Wilder- ness and contains habitat for 13 rare and locally endemic plant species (Fertig and Rey- nolds 2009). Most of the Wilderness Area is contained within the broad bowl of Ash- down Creek and its main tributaries that drain the Cedar Breaks Amphitheater. For- ests along the upper slopes of the bowl are dominated by Engelmann spruce (Picea engelmannii) and Subalpine fir (Abies lasiocarpa). Lower slopes and the valley bottom are clothed primarily by White fir (Abies concolor), Douglas-fir (Pseudotsuga menziesii), Ponderosa pine (Pinus ponderosa), and scattered patches of Quaking aspen (Populus tremuloides). Ashdown Creek is a perennial, boulder-lined stream of Claron alluvium lined with patches of Narrowleaf cottonwood (Populus angustifolia) and open gravel bars. Small meadows occur sporadically, especially on exposures of volcanic clay soil on ridgetops and slopes. At 7043 acres, Ashdown Gorge Wilderness is about 12% larger than Cedar Breaks National Monument and is also about 600 feet lower in elevation (the full elevational range of the wilderness is 7500-10500 feet).

Aside from the Twisted Forest area, relatively little botanical exploration has been conducted within the Ashdown Gorge Wilderness Area (Mark Madsen, Dixie NF botanist, personal communication). Starting in 2006, I have made 18 trips into the Ashdown Gorge Wilderness to map the distribution of rare plants and to develop a baseline checklist of the area’s flora (Figure 2). Though still preliminary, the results of these studies are shown in Appendix A and summarized in Table 3.

To date, 308 vascular plant species from 51 families have been documented in the Ash- down Gorge Wilderness Area (Table 3). Of these, 274 species are represented by voucher specimens and 34 are known from photographs or observations (cover and Figure 5). As many as 20 of the species recorded for the study area may be new distribution records for Iron County, Utah. The flora of Ashdown Gorge Wilderness ac- counts for 35% of the 891 species now known for Iron County and 8.6% of the 3594 native and naturalized vascular plants of Utah (Welsh et al. 2008).

Ecologically, trees and shrubs are the dominant components of the vegetation of Ash- down Gorge, but collectively these species represent just 16.9% of the flora of the area. Perennial forbs account for nearly 57% of all species in the flora, followed by perennial grasses with almost 16% of total species richness. Annual forbs and grasses contribute

8.5% of the flora. Ferns and fern-allies are relatively poorly represented in the wilderness, with just 1.9% of all species (Table 3).

At least 34 of the plant species from the Ashdown Gorge Wilderness are local or regional endemics restricted primarily to the mountains of southern Utah. Of these, 15 are considered species of management concern by Cedar Breaks National Monument (Fertig and Reynolds 2009). Nearly 82% of the species in the wilderness are widespread over Utah and western North America. Only 16 species from the wilderness are not native to Utah and none are recognized as noxious weeds by the state of Utah. The percentage of introduced species in the Ashdown Gorge Wilderness Area (5.2%) is less than half the statewide average of 13.5% (Fertig 2007).

Comparison of the Floras of Cedar Breaks National Monument and Ashdown Gorge Wilderness Area

Based on present knowledge, Cedar Breaks National Monument has 57 more vascular plant species than its neighbor, the Ashdown Gorge Wilderness Area. Of the 365 plant taxa recorded for Cedar Breaks, 118 species (32.3%) are not yet known from the Ash- down Gorge Wilderness (Table 4). Likewise, 61 of the 308 plant taxa from the wilderness area (19.8%) have not been found in the monument. Overall, 247 species are known from both areas.

Jaccard’s Coefficient of Similarity (JCS)* is a useful way to compare the similarity of two different floras based on their total species richness and number of taxa shared in

*The formula of Jaccard’s Coefficient of Similarity is defined as C/N1 + N2 - C where C = the number of species shared in common between two floras, N1 = the number of species in flora # 1, and N2 = the number of species in flora # 2. The higher the value of JCS, the more similar the two floras being com- pared.

common. Pairs of floras with high JCS values typically share a high number of species in common, are of comparable area, and often are relatively close geographically or have similar vegetation types and environments. The JCS value for Cedar Breaks Na- tional Monument and Ashdown Gorge Wilderness is 0.579 (Table 5). This value is the highest of any pair wise comparison between Cedar Breaks and other national parks, monuments, historical sites, and recreation areas in Utah managed by the National Park Service or Bureau of Land Management’s National Landscape Conservation Sys- tem (Fertig 2009b). The flora of Ashdown Gorge Wilderness Area is nearly twice as similar to Cedar Breaks as the next closest park, Bryce Canyon National Park. The similarity of Cedar Breaks National Monument to other protected areas drops precipi- tously, as the other units lack the extensive Claron habitats found in Ashdown Gorge and Bryce Canyon and are more geographically distant.

If Cedar Breaks National Monument were expanded to include Ashdown Gorge Wilder- ness Area, as proposed recently by the Iron County Commission, the total flora of “Cedar Breaks National Park” would reach 426 species. Cedar Breaks would still rank 10th in size among Utah parklands, but would be nearly equal in species richness to Natural Bridges National Monument (currently in ninth place with 428 taxa, Table 5). Among the notable additions to the Cedar Breaks flora would be one new plant family (Juncaginaceae), five more introduced species (Capsella bursa-pastoris, Descurainia sophia, Thlaspi arvense, Trifolium repens, and Veronica biloba), and four additional local or regional endemics (none of which are sufficiently rare to warrant special management attention). Adding the Ashdown Gorge Wilderness would also increase the number of shrub species in the park by 17% and the number of annual forbs by 52% (Tables 1 & 4).

Additional field surveys will undoubtedly continue to increase the known vascular plant flora of the Ashdown Gorge Wilderness Area and Cedar Breaks National Monu- ment. Surveys are especially needed in springs, boggy wetlands, and White fir- Ponderosa pine forests in the bottom of Ashdown Canyon in the wilderness and monument. The early season flora of upland meadows (especially dry, south-facing slopes) is also under-sampled within the Ashdown Gorge Wilderness. Between 50-100 plant species probably remain to be documented within the combined study area. Full documentation of the floras of both Cedar Breaks National Monument and the Ashdown Gorge Wilderness Area is especially important as these two areas are among the best protected sites for native biological diversity in the high plateaus region of south- central Utah. Knowing the diversity of plant species in the Cedar Breaks area, especially rare taxa and invasive weeds, will enable land managers to better meet their management responsibilities.

Appendix A. Annotated Checklist of the Flora of Ashdown Gorge Wilderness Area, Iron County, Utah

Family: Family concepts and nomenclature follow A Utah Flora fourth edition (Welsh et al. (2008). Widely used alternative family names are included in parentheses. Families are listed alphabetically rather than phylogenetically.

Species Name: Nomenclature for scientific names and taxonomic concepts are derived from Welsh et al. (2008). Scientific names are arranged in alphabetical rather than phylogenetic order.

Synonyms: Pertinent synonyms are included for species with alternative scientific names in other recent state or regional floras.

Common Name: Common Names are derived primarily from Welsh et al. (2008) and the Intermountain Flora (Holmgren et al. 2005 and preceding volumes).

Life Form: Life form describes the stature and growth habit of typical members of a species at reproductive maturity. Trees are woody perennials with a single stem or trunk and are typically over 3.5 m tall. Shrubs are woody perennials with one to many trunks arising from near the base of the plant and are usually less than 3.5 m tall. Per- ennial Forbs (P-Forb) are broad-leaved dicots or monocots with non-woody stems (at least above ground level) that live for multiple years. Annual Forbs (A-Forb) are broad -leaved dicots or monocots with non-woody stems that complete their life cycle in one year. Perennial Graminoids (P-Grss) are linear-leaved, grass-like monocots that live for multiple years. Annual Graminoids (A-Grss) are linear-leaved, grass-like monocots that complete their life cycle in one year. Ferns and fern-allies (Fern) are non- flowering vascular plants that reproduce by spores.

Range: Range represents the distribution of a species within Utah and the state’s con- tribution to the plant’s overall global range. Disjunct (Disj) taxa have their Utah distribution separated from the main, contiguous portion of their range by a gap of more than 800 km (ca 500 miles). Introduced (Intro) taxa are those that are not native to Utah or North America but have become naturalized (breeding on their own without human assistance). Local Endemics (Loc En) are taxa whose entire global range is restricted to an area of less than 16,500 km2 (ca 6,370 mi2, or 1° of latitude x 2° of longitude). Peripheral (Periph) taxa have a widespread global distribution but occur at the margin of their contiguous range in Utah and occupy less than 5% of the state’s area (usually only within a few miles of the state border). Regional endemics (Reg En) are taxa with a global range of 16,500-250,000 km2 (an area about the size of the state of Wyoming). Sparse taxa occur widely across Utah or North America but their range within the state is small and patchy, with populations restricted to specialized or uncommon habitats. Widespread (Wide) taxa have global ranges exceeding 250,000 km2 and occur over at least 10% of the state.

Status: Species documented within Ashdown Gorge Wilderness based on confirmed voucher specimens are considered Present (Pres). Taxa known only from unvouchered

observations or photographs are considered Observed (Obs).

Pop. Size (Population Size): Population size refers to the abundance and frequency of a species within the Ashdown Gorge Wilderness Area based on personal observations. Abundant (Abun) taxa have large populations, a broad ecological amplitude (often being dominant in one to several vegetation types), or occur extensively across the wilderness area. Common (Com) taxa have large local populations but may be restricted to a single vegetation type or do not occur across the entire wilderness area. Uncommon (Unc) species have low to medium-sized populations, a narrow ecological amplitude (or at least contribute relatively little to total vegetative cover), or a small range across the wilderness area. Rare taxa usually have low population numbers and are restricted to a single location in the area.

Source: Sources are the basis for inclusion of a species in the checklist. Most sources are voucher specimens, though a few are photographs or observation records. Speci- men data include the collector(s), collection number, and repository.

Year Doc: Year documented indicates the first year in which a species was collected or observed within the Ashdown Gorge Wilderness Area during this study. This year does not necessarily correspond with the date of the voucher specimen cited under Source.

Comments: This column includes additional comments on the status of a particular species, the place of origin of introduced species, legal status, location of type collections from the vicinity, and other data.
