Global State element element County Scientific Name Common Name rank1 rank2 San Miguel Stipa comata - west Western Slope Grasslands G3 S2 1Global rarity ranks are based on the range-wide status of an element. Global ranks are denoted with a “G” followed by a character. These ranks should not be interpreted as legal designations.

Basic Ranks:

G# Numeric rank: A numeric rank (G1 through G5) of relative endangerment based primarily on the number of occurrences of the element globally.

G1 Critically imperiled globally because of extreme rarity or because of some factor(s) making it especially vulnerable to extinction. (Typically 5 or fewer occurrences or very few remaining individuals or acres)

G2 Imperiled globally because of rarity or because of some factor(s) making it very vulnerable to extinction throughout its range. (6 to 20 occurrences or few remaining individuals or acres)

G3 Either very rare and local throughout its range or found locally (even abundantly at some of its locations) in a restricted range (e.g., a single western state, a physiographic region in the East) or because of other factors making it vulnerable to extinction throughout its range. (21 to 100 occurrences)

G4 Widespread, abundant, and apparently secure globally, though it may be quite rare in parts of its range, especially at the periphery. Thus, the element is of long-term concern. (Usually more than 100 occurrences)

G5 Demonstrably widespread, abundant, and secure globally, though it may be quite rare in parts of its range, especially at the periphery.

G#G# Numeric range rank: A range between two of the numeric ranks. Denotes range of uncertainty about the exact rarity of the element; ranges can not skip more than one rank (eg. G1G4 is not allowed).

G? Unranked: Element is not yet ranked globally.

GU Unrankable: Possibly in peril range-wide but status uncertain; need more information. NOTE: This rank should be used sparingly. Whenever possible, assign the most likely rank and add a question mark (e.g., G2?) to express uncertainty, or use a range (e.g., G2G3) to delineate the limits (range) of uncertainty.

GH Historical: Of historical occurrences throughout its range, i.e., formerly part of the established biota, with the expectation that it may be rediscovered (e.g., Bachman's Warbler).

GX Extinct: Believed to be extinct throughout range (e.g., Passenger Pigeon) with virtually no likelihood that it will be rediscovered.

HYB Hybrid: Element represents a hybrid of species.

Version: 18 July 2005 Appendix A—Plant and Natural Communities at the Subregional Scale Page 38 of 39

Subrank:

T Taxonomic subdivision: rank applies to a subspecies or variety.

Qualifiers:

? Inexact: Denotes inexact numeric rank.

Q Questionable taxonomy: Taxonomic status is questionable; numeric rank may change with taxonomy.

C Captive or cultivated: Element is presently extant globally only in captivity or cultivation.

Note: a) Other factors in addition to the number of occurrences are considered when assigning a rank, so the numbers of occurrences suggested for each numeric rank above are not absolute guidelines.

b) Global numeric ranks should not be subdivided (only state ranks may subdivide into decimal fractions -- eg. S1.1, S1.2, S1.3). State rarity ranks are based on the status of an element in an individual state.

2State ranks are denoted with a “S” followed by a character. These ranks should not be interpreted as legal designations.

Basic ranks:

S# Numeric rank: A numeric rank (S1 through S5) of relative endangerment based primarily on the number of occurrences of the element within the state.

S1 Critically imperiled in the state because of extreme rarity or because of some factor(s) making it especially vulnerable to extirpation from the state. (Typically 5 or fewer occurrences or very few remaining individuals or acres)

S2 Imperiled in the state because of rarity or because of some factor(s) making it very vulnerable to extirpation from the state. (6 to 20 occurrences or few remaining individuals or acres)

S3 Rare and uncommon in the state. (21 to 100 occurrences)

S4 Widespread, abundant, and apparently secure in state, with many occurrences, but the element is of long-term concern. (Usually more than 100 occurrences)

S5 Demonstrably widespread, abundant, and secure in the state, and essentially ineradicable under present conditions.

S#S# Numeric range rank: A range between two of the numeric ranks. Denotes range of uncertainty about the exact rarity of the element. Ranges can not skip more than one rank (e.g., S1S4 is not allowed).

S? Unranked: Element is not yet ranked in the state.

Version: 18 July 2005 Appendix A—Plant and Natural Communities at the Subregional Scale Page 39 of 39

SU Unrankable: Possibly in peril in the state, but status uncertain; need more information. NOTE: This rank should be used sparingly. Whenever possible, assign the most likely rank and add a question mark (e.g., S2?) to express uncertainty, or use a range (e.g., S2S3) to delineate the limits (range) of uncertainty.

SE Exotic: An exotic established in the state; may be native in nearby regions (e.g., house finch or catalpa in eastern U.S.)

SE# Exotic numeric: An exotic established in the state that has been assigned a numeric rank, as with S1through S5.

SA Accidental: Accidental or casual in the state (i.e., infrequent and far outside usual range). Includes species (usually birds or butterflies) recorded once or twice or only at very great intervals, hundreds or even thousands of miles outside their usual range; a few of these species may even have bred on the one or two occasions they were recorded; examples include European strays or western birds on the East Coast and vice-versa.

SZ Zero occurrences: Not of practical conservation concern in the state, because there are no definable occurrences, although the taxon is native and appears regularly in the state. An SZ rank will generally be used for long distance migrants whose occurrences during their repeated visitation to the same locations are transitory too and dispersed to be reliably identified, mapped, and protected. In other words, the migrant regularly passes through the subnation, but enduring, mappable EOs cannot be defined.

Typically, the SZ rank applies to a non-breeding population (N) in the subnation -- for example, birds on migration. An SZ rank may in a few instances also apply to a breeding population (B), for example certain Lepidoptera which regularly die out every year with no significant return migration.

Note: a) Other factors in addition to number of occurrences are considered when assigning a rank, so the numbers of occurrences suggested for each numeric rank above are not absolute guidelines.

b) State ranks may be subdivided by using decimal extensions .1, .2 and .3 (e.g.,S1.3).

Introduction

Current Landscape Condition Assessment

Plant Species and Natural Communities of Concern Appendix A provides the tables of plant species (Table A-1) and natural communities (Table A- 2) of concern identified by the Colorado National Heritage Program (CNHP) for the Colorado portion of the Subregional Scale. Of the 492 plant species of concern, 114 (23%) of them are imperiled (G2/S2) or critically imperiled (G1/S1) at both the global and state levels. Likewise, of the 738 natural communities, 97 (13%) of them are imperiled (G2/S2) or critically imperiled (G1/S1) at both the global and state levels.

Potential Conservation Areas There are 750 Potential Conservation Areas (PCAs) identified by the Colorado Natural Heritage Program for the Colorado portion of the Subregional Scale (Appendix B). PCAs have been identified

Grand Mesa, Uncompahgre, and Gunnison National Forests

Plant Species and Natural Communities of Concern Appendix D is a spreadsheet of the plant species and natural communities of concern (i.e., element occurrence—EO—data) provided by the CNHP for the GMUG. The spreadsheet includes the following column headings: Ranger District; Quadrangle; Major Group; EO ID; State Element ID; Global Scientific Name; State Scientific Name; State Common Name; GRank and SRank; Precision; Last Seen; Directions; Habitat Description; Occurrence Information; and Best Source. Please refer to the CNHP 2003 CD provided to the USDA Forest Service for additional information regarding the use of this data. Appendix D is available in the administrative record. All five Geographic Areas (GA) of the GMUG have occurrences of vascular plant species and natural communities of concern (Figure 3). The largest contiguous delineation for the GMUG covers almost the entire North Fork Valley and the northern portion of the Gunnison Basin GAs (Figure 3). For greater detail of the EOs occurring in the individual GAs please see the following Geographic Area Scale section.

Potential Conservation Areas The CNHP identified 151 PCAs completely within or over lapping the boundaries of the GMUG (Appendix E, Figure 4). Twenty-eight of the PCAs have outstanding (B1) or very high (B2) biodiversity significance, 11 of them need protection action now (P1) or within the next five years (P2), and 13 of them require management action within one (M1) or five years (M2) to prevent loss of the element occurrences contained in the PCAs. Two of the PCAs (Gunnison Basin and Unaweep Seep) are of particular importance. Gunnison Basin, located in the Gunnison Basin GA, has outstanding biodiversity significance, needs protection action within the next five years, and may require management action within one year to prevent the loss of the plant and bird species of significance in this area. Unaweep Seep, located in the Uncompahgre Plateau GA, has very high biodiversity significance, needs protection action within the next five years, and may require management action with the next five years to prevent the loss of habitat for the six natural communities, two plant and one butterfly species that are significant in this area.

Potential Conservation Areas There are 66 PCAs identified by the CNHP for the Gunnison Basin GA (Figure 10, Table 5). Fourteen of the PCAs have outstanding (B1) or very high (B2) biodiversity significance, three of them need protection action within the next five years (P2), and eight of them require management action within one (M1) or five years (M2) to prevent loss of the element occurrences contained in the PCAs. The Gunnison Basin PCA (site #43 on Figure 10) is 553,081 acres and is of particular importance because it has outstanding biodiversity significance, needs protection action within the next five years, and may require management action within one year to prevent the loss of the plant and bird species of significance in this area. According to the CHNP PCA database: The Gunnison Basin site supports good (B-ranked) occurrences of the globally- and state- critically imperiled (G1/S1) Gunnison sage grouse (Centrocercus minimus), designated a species of special concern by the Colorado Division of Wildlife and a candidate for listing under the Federal Endangered Species Act. This site represents the largest and most likely to succeed population of the Gunnison sage grouse. (That is, there are no remaining A-ranked occurrences.) This grouse was recently described as a distinct species and has a high potential for being federally listed as an endangered species due to a declining population. Within the Gunnison sage grouse range (i.e., southwestern Colorado and southeastern Utah), only Gunnison County has a secure population (Gunnsion Sage Grouse Conservation Plan 1997). In 1995, the spring population of sage grouse in the Gunnison Basin was about 2,200 birds (Gunnison Sage Grouse Conservation Plan 1997). Factors clearly implicated in the long-term decline of sage grouse are habitat loss; habitat fragmentation (caused by roads, powerlines, reservoirs, land conversion, land treatments, etc.); and habitat degradation caused by land treatments and other uses which have changed grass, forb, and sagebrush composition, reduced organic material in the soil, and increased the loss/movement of soil resulting in changes in water table levels, and basic soil productivity. Sage grouse are specialists of sagebrush ecosystems and have not adapted to changing land uses. This site also supports nearly the entire world's population of the Gunnison milkvetch (Astragalus anisus) (G2/S2).

Potential Conservation Areas There are 21 PCAs identified by the CNHP for the Uncompahgre Plateau GA (Figure 19, Table 11). Five of the PCAs have outstanding (B1) or very high (B2) biodiversity significance, two of them need protection action within the next five years (P2), and three of them require management action within five years (M2) to prevent loss of the element occurrences contained in the PCA. The Unaweep Seep PCA (site #4 on Figure 19) is 19,922 acres and is of particular importance because it has outstanding biodiversity significance, needs protection action within the next five years, and may require management action within five years to prevent the loss of the plant and bird species of significance in this area. According to the CHNP PCA database: This site supports the largest known Colorado population of the globally imperiled (G4T2) Nokomis fritillary butterfly (Speyeria nokomis nokomis). Although there is a larger population in Utah, there appears to be a genetic difference between the two. The butterfly larvae feed specifically on bog violets (Viola nephrophylla) growing in open areas. The violets were found to grow in a very narrow range of moisture, usually on toe slopes at the base of seeps or on hummocks, where their roots can reach open water. Nectar plants, such as Joe Pye weed and bull thistle (Cirsium vulgare), used by the adult butterflies, are also found here. The Yuma skipper (Ochlodes yuma), which is vulnerable in Colorado (S2S3) has also been documented from this site. This skipper is found in freshwater marshes, stream courses, ponds, and seeps/springs. It is common in its limited habitat in California, Nevada, Utah, Colorado, northern New Mexico, and Arizona. Western Colorado represents the eastern periphery of this species range. It uses common reed (Phragmites australis) as its host plant. The site supports the globally critically imperiled (G1Q) boxelder-narrowleaf cottonwood riparian forest (Acer negundo-Populus angustifolia/Celtis reticulata) which occurs in dense patches around several small channels fed by the seep. Currently, this association is known from only one stand in

Colorado. Additional surveys should be conducted in western Colorado, southern Utah, northern Arizona, and northwest New Mexico to identify its distribution. The site also supports the globally imperiled (G2G3) beaked spikerush emergent wetland association (Eleocharis rostellata), and numerous wetland and riparian plant associations, which are vulnerable in Colorado (S3). These wetland plant associations support the richest diversity of plant and bird life of any other BLM parcel in the Grand Junction Resource Area (BLM 1999). The giant helleborine (Epipactis gigantea) which is vulnerable throughout its range is abundant at this site. This orchid grows along streambanks and near springs and seeps in the pinyon-juniper zone. Although the species is widespread in the southwestern region, its specific habitat requirements limit its numbers. The western yellowbelly racer (Coluber constrictor mormon), which is vulnerable in Colorado (S2S3), is found in a wide variety of habitats: meadow, prairies; open chaparral, pinyon-juniper woodland; and riparian woodland. In western Colorado, it occurs below about 5500 ft., in agricultural areas, lowland riparian habitats, and occasionally in semi-desert shrublands.
