Appendix C: Species of Concern




MTNHP Species of Concern


The term "species of concern" includes taxa that are at-risk or potentially at-risk due to rarity, restricted distribution, habitat loss, and/or other factors. The term also encompasses species that have a special designation by organizations or land management agencies in Montana, including: Bureau of Land Management Special Status and Watch species; U.S. Forest Service Sensitive and Watch species; U.S. Fish and Wildlife Service Threatened, Endangered and Candidate species.

Heritage Program Ranks (Global and State)


Taxa are evaluated and ranked by the Heritage Program on the basis of their global (range-wide) status, and their state-wide status according to a standardized procedure used by all Natural Heritage Programs. These ranks are used to determine protection and data collection priorities, and are revised as new information becomes available.

For each level of distribution—global and state—species are assigned a numeric rank ranging from 1 (greatest concern) to 5 (least concern). This reflects the species relative endangerment and is based primarily on the number of occurrences of that species globally or within the state. However, other information such as date of collection, degree of habitat threat, geographic distribution patterns and population size and trends is considered when assigning a rank, and the number of occurrences listed below are suggestions, not absolute criteria.


For example, Clustered lady's slipper (Cypripedium fasciculatum) is ranked G4 S2. Globally the species is apparently secure, while in Montana it is imperiled because of rarity, or because of other factors making it demonstrably vulnerable to extirpation.


1

Critically imperiled because of extreme rarity (5 or fewer occurrences, or very few remaining individuals), or because of some factor of its biology making it especially vulnerable to extinction.

2

Imperiled because of rarity (6 to 20 occurrences) or because of other factors demonstrably making it vulnerable to extinction throughout its range.

3

Either very rare and local throughout its range, or found locally (even abundantly at some of its locations) in a restricted range, or vulnerable to extinction throughout its range because of other factors; in the range of 21 to 100 occurrences.

4

Apparently secure, though it may be quite rare in parts of its range, especially at the periphery.

5

Demonstrably secure, though it may be quite rare in parts of its range, especially at the periphery.

U

Possibly imperiled, but status uncertain; more information needed.

H

Historically known; may be rediscovered.

X

Believed to be extinct; historical records only.

Other Heritage Codes



G#G#

S#S#


Numeric range rank: A range between two of the numeric ranks. Denotes range of uncertainty about the exact rarity of the species.

Subrank


T

Rank for subspecific taxon (subspecies, variety, or population); appended to the global rank for the full species, e.g. G4T3

Qualifiers



A

Accidental in the state; including species (usually birds or butterflies) recorded very infrequently, hundreds or thousands of miles outside their usual range.

B

Breeding status of a migratory species. Example: S1B, SZN - breeding occurrences for the species are ranked S1 (critically imperiled) in the state, nonbreeding occurrences are not ranked in the state.

E

An exotic established in the state; may be native in nearby regions.

HYB

Element represents a hybrid of species

N

Non-breeding status of a migratory species. Example: S1B, SZN - breeding occurrences for the species are ranked S1 (critically imperiled) in the state, nonbreeding occurrences are not ranked in the state.

P

Indicates the element may potentially occur in the state.

Q

Taxonomic questions or problems involved, more information needed; appended to the global rank.

R

Reported in the state; but lacking documentation which would provide a basis for either accepting or rejecting the report.

T

Rank for subspecific taxon (subspecies, variety, or population); appended to the global rank for the full species.

Z

Ranking not applicable.

#

A modifier to SX or SH; the species has been reintroduced but the population is not yet established.

?

Inexact or uncertain; for numeric ranks, denotes


BLM = Bureau of Land Management

USFS= U.S. Forest Service

USFWS-ESA = U.S. Fish and Wildlife Service-Endangered Species Act


BLM Status




Sensitive or Special Status

Special Status animals or Sensitive plant species: proven to be imperiled in at least part of its range and documented to occur on BLM lands.

Watch

Watch species: either known to be imperiled and suspected to occur on BLM lands; suspected to be imperiled and documented on BLM lands; or needing further study for other reasons.

USFS Status




Threatened

Listed as Threatened (LT) or Endangered (LE) under the Endangered Species Act or proposed for listing (P); and known or suspected to occur on national forests.

Sensitive

Sensitive species, subspecies, or variety for which the Regional Forester has determined there is a concern for population viability rangewide or in the region.

USFWS-ESA Status




Listed endangered

Listed as Endangered under the Endangered Species Act.

Listed threatened

Listed as Threatened under the Endangered Species Act.

Proposed delisting

Proposed for delisting as Threatened under the Endangered Species Act.

Proposed endangered

Proposed for listing as Endangered under the Endangered Species Act.

Proposed threatened

Proposed for listing as Threatened under the Endangered Species Act.

Candidate

Candidate for listing under the Endangered Species Act.

Proposed Critical Habitat

Specific geographic areas, whether occupied by a listed species or not, that are essential for its conservation and that are proposed for formal designation.
