APPENDIX 3C FEDERAL, STATE, AND COLORADO NATURAL HERITAGE PROGRAM SPECIES STATUS CODE DEFINITIONS Federal Status: U.S. Fish and Wildlife Service (58 Federal Register 51147, 1993) and (61 Federal Register 7598, 1996) FE Listed Endangered: defined as a species, subspecies, or variety in danger of extinction throughout all or a significant portion of its range. FT Listed Threatened: defined as a species, subspecies, or variety likely to become endangered in the foreseeable future throughout all or a significant portion of its range. State Status: The Colorado Division of Wildlife has developed categories of imperilment for nongame species (refer to [he Colorado Division of Wildlife's Chapter 10 - Nongame Wildlife of the Wildlife Commission's regulations). SE Endangered: those species or subspecies of native wildlife whose prospects for survival or recruitment within this state are in jeopardy, as determined by the Commission. ST Threatened: those species or subspecies of native wildlife which, as determined by the Commission, are not in immediate jeopardy of extinction but are vulnerable because they exist in such small numbers, are so extremely restricted in their range, or are experiencing such low recruitment or survival that they may become extinct. SC Special Concern: those species or subspecies of native wildlife [hat have been removed from the state threatened or endangered list within the last five years; are proposed for federal listing (or are a federal listing "candidate species") and are not already state listed; have experienced, based on the best available data, a downward trend in numbers or distribution lasting at least five years that may lead to an endangered or threatened status; or are otherwise determined to be vulnerable in Colorado. Colorado Natural Heritage Program (CNHP) Imperilment Ranks State imperilment ranks are based on the status of a species in an individual state. These tanks should not be interpreted as legal designations. Sl Critically imperiled globally/state because of rarity (5 or fewer occurrences in the world/state; or 1,000 or fewer individuals), or because some factor of its biology makes it especially vulnerable to extinction. S2 Imperiled globally/state because of rarity (6 to 20 occurrences, or 1,000 to 3,000 individuals), or because other factors demonstrably make it very vulnerable to extinction throughout its range.
