Status Codes*:<br />

BCR = On Bird Conservation Region 16 (Southern Rockies/Colorado Plateau) Birds of Conservation Concern List (USDI FWS 2002).<br />
BLM = On USDI Bureau of Land Management Colorado Bureau of Land Management Sensitive Fish and Wildlife Species List (USDI<br />
BLM 2000). Effects to the species were analyzed in the Biological Evaluation.<br />
ESA = Listed under the federal Endangered Species Act of 1973 as Threatened, Endangered, Proposed or Candidate for federal listing and<br />
known or likely to occur or have habitat on lands administered by the SJFO (USDI FWS 2005). Effects to the species were<br />
analyzed in the Biological <strong>Assessment</strong>.<br />
FS = On USDA Forest Service Rocky Mountain Region (Region 2) Regional Forester’s Sensitive Species List (USDA FS 2003). Effects to<br />
the species were analyzed in the Biological Evaluation<br />
MIS = Management Indicator Species for the San Juan National Forest. Effects to the species were analyzed in a Wildlife Report.<br />
PIF = On Colorado Partners in Flight Physiographic Area 62 List (Beidleman 2000).<br />
State = On Colorado Division of Wildlife’s Listing of Endangered, Threatened and Wildlife Species of Special Concern (CDOW 2007).<br />
Likelihood of Occurrence @ :<br />
High = Species is known or thought likely to occur in the project area during either breeding or non-breeding seasons due to documented<br />
occurrence or presence of suitable habitat. Species may occur in small numbers or in widely distributed areas.<br />
Moderate = May occur in the project area during some years, but is unlikely to breed due to lack of habitat. Or, occurrence in the project<br />
area is irregular and unpredictable and during the non-breeding season only.<br />
Low = Species is not known or thought likely to breed or winter in the project area due to lack of suitable habitat.<br />
