CHAPTER 3 <br />AFFECTED ENVIRONMENT AND ENVIRONMENTAL CONSEQUENCES <br />Table 3.7-2 <br />Special Status Wildlife Species Potentially Occurring <br />Within the Project Area <br />Common Name Scientific Name <br />Federally Listed Species <br />Bald Eagle Haliaeetus leucocephalus <br />Southwestern Willow Flycatcher Empidonax traillii extimus <br />Mexican Spotted Owl Strix occidentalis lucida <br />Black-footed Ferret Mustela nigripes <br />Federal Proposed Species <br />Canada Lynx Lynx canadensis <br />Mountain Plover Charadrius montanus <br />Federal Candidate Species <br />Boreal Toad Bufo boreas boreas <br />Source: U.S. Fish and Wildlife Service (June 23, 1999 memorandum) <br />The peregrine falcon was officially delisted in 1999. There are no documented prairie dog colonies of <br />sufficient size to support black-footed ferrets within the project area, nor have there been any recent <br />confirmed sightings of black-footed ferrets in the project area. <br />The bald eagle is associated with aquatic ecosystems throughout its range, which formerly included most <br />of the North American continent. Bald eagles are known to feed and roost at Lemon Reservoir and along <br />the Animas and La Plata Rivers. Navajo Reservoir is an important wintering area in New Mexico and I <br />Colorado, as are the Animas and La Plata Rivers. Eagles utilize the Pine River and Florida River areas as <br />well. Bald eagles arrive in the area by mid-November and leave by late March or early April. Only a <br />small number of bald eagles remain in the southwest each spring to nest and rear young. An active bald I <br />eagle nest is reported near Lemon Dam (Stransky 2000). <br />Mexican Spotted Owl <br />On November 4, 1991, the Mexican spotted owl (Strix occidentalis lucida) was proposed for listing as <br />threatened. The species is now listed. Reclamation, in conjunction with the Service, conducted a field <br />survey designed to detect Mexican spotted owls in the Ridges Basin Reservoir area (1996 FSFES). No <br />owls were detected, and it was determined that the species would not be affected by construction and <br />operation of the project. The Service concured with this finding in an August 3, 1992 memorandum <br />' M (Service 1992) and in the 2000 Biological Opinion (Service 2000a). I <br />Loggerhead Shrike <br />The loggerhead shrike (Lanius ludovicianus) was included as a candidate species on the Service's species <br />list in a June 1, 1994, memorandum. Reclamation's Biological Assessment concluded the project would <br />be unlikely to adversely affect the loggerhead'shrike, and on July 7, 1995, the Service provided <br />Ntc»As ?u4cilJZ-G?(ZAV? <br />Qc.Ek?P?cr N - QA?E ' ?? <br />'1 7?lYldAc1e©nsArLic1ion Via?
