Lists taken from U.S. Fish and Wildlife Service Region 6 web site (http://www.r6.fws.gov/endspp) and from State BLM Director's Sensitive Species List, edited for <br />UFO by B. Dickerson <br />Symbols and codes for federally listed species: <br />* Water depletions in the Upper Colorado River and San Juan River Basins, <br />may affect the species and/or critical habitat in downstream reaches in other states. <br />Water depletions in the South Platte River may affect the species and/or critical habitat in downstream reaches in other states. <br />© There is designated critical habitat for the species within the county. <br />T Threatened <br />E Endangered <br />P Proposed <br />X Experimental <br />C Candidate <br />GROUP: Colorado Natural Heritage Program (CNHP) <br />CNHP - Global Rarity Rankine is based on the range-wide status of a species. <br />G1- Critically imperiled globally because of extreme rarity (5 or fewer occurrences, or very few remaining individuals), or because of <br />some factor of its biology making it especially vulnerable to extinction. (Critically endangered throughout its range). <br />G2-Imperiled globally because of rarity (6 to 20 occurrences), or because of other factors demonstrably making it very vulnerable to <br />extinction throughout its range. (Endangered throughout its range). <br />G3-Very rare or local throughout its range or found locally in a restricted range (21 to 100 occurrences). (Threatened throughout its <br />range). <br />G4-Apparently secure globally, though it might be quite rare in parts of its range, especially at the periphery. <br />G5-Demonstrably secure globally, though it may be quite rare in parts of its range, especially at the periphery. <br />T- Taxa of subspecies or varieties, ranked on same criteria as G1-G5. <br />CNHP - State Rarity Rankine is based on the status of a species (relative abundance of individuals) in each state. <br />S1- Critically imperiled in state because of extreme rarity (5 or fewer occurrences, or very few remaining individuals), or because of <br />some factor of its biology making it especially vulnerable to extirpation from the state. (Critically endangered in state). <br />S2- Imperiled in state because of rarity (6 to 20 occurrences), or because of other factors demonstrably making it very vulnerable to <br />extirpation from the state. (Endangered or threatened in state). <br />S3- Rare in state (21 to 100 occurrences). <br />S#B- Refers to the breeding season imperilment of elements that are not permanent residents. <br />S#N- Refers to the non-breeding season imperilment of elements that are not permanent residents. Where no consistent location can <br />be discerned for migrants or non-breeding populations, a rank of SZN is used. <br />SZ- Migrant whose occurrences are too irregular, transitory, and/or dispersed to be reliably identified, mapped, and protected. <br />The World Conservation Union (IUCN) <br />LR - Taxon is lower risk, does not satisfy the criteria for Critically Endangered, Endangered or Vulnerable. <br />Ic -one of three subcategories under LR. Taxa which do not qualify for Conservation Dependent or Near Threatened <br />AGENCY: U.S. Forest Service, Region 2 <br />FS - Sensitive: those plant and animal species identified by the Regional Forester for which population viability is a concern as evidenced by: <br />a. Significant current or predicated downward trends in population numbers or density. <br />b. Significant current or predicated downward trends in habitat capability that would reduce a species' existing <br />distribution. <br />STATE: Colorado Division of Wildlife <br />SC -Species of Special Concern <br />Bluerock Energy Corp.
