<br />in the N'ucla study area (Map 11-2, Appendix A). An extensive burrow by <br />burrow searc*r for black-footed ferrets and their sign (e.g., tren:.hing <br />and scats) was conducted in late May, 1979. A total of 123 burrows encom- <br />passing approximately 16 acres were systeratieally searcl-.ed. ivo black- <br />foobed ferrets or their sign wire observed on the study area. <br />The gray wolf fonrerly occurred over much of the United States. Due tv <br />widespread habitat destruction and human harassrtent, the gray wolf in <br />Colorado is limited to a few captive individuals WU(d, n.d.). I3o gray <br />wolves have i~een reported in this area of Colorado. <br />A number of whooping cranes have been hatched oral raised by sanahill crane <br />foster parents in USFWS experimental program at Gray's Lake :.ational Wild- <br />life Refuge, southeast Idaho. This is an ongoing program at Gray's Lake <br />amt the USFitiS placed approximately 20 whooping crane eggs in sandhill <br />crane nests in the spring of 1979; 6 have survived to date (personal cafm- <br />unication, 1979, Mr. Philip Lehenbaver, USFWS). Since some of the whooping <br />• ~--` cranes raised in this experimental program have remained associated with <br />their foster rarents, suitable habitat within the range of greater sandhill <br />cranes must also be considered potential whooping crane swrmer habitat. <br />Aittaugh m greater sandhill crane habitat exists on the ir'ucla study area, <br />the Miguel River Valley about 8 miles west of the study area may be used for <br />migration. However, to date, no whooping cranes have been reported whir <br />greater sandhill cranes in this area of Colorado. <br />TMP(?IiTANT WIIDLII~'E HABITAT <br />For the purlvses of this study, inportant wildlife habitat can be defined <br />by two criteria: habitat critical to the support of important wildlife <br />species (i.e., threatened or endangered animals or other vertebrates prot- <br />ected bf state or federal law and certain game aninwls) and habitats <br />offering both envirormiental aril vegetarive situations which contribute <br />to m3xLTtsn wildlife diversity for the region. _ The rmrle deer oral the rirr.- <br />necked pheasant are the only important ~peries that occur near the study <br />-A9- <br />• <br />dUM 1 i t480 <br />(Revised August 2006) Attachment 2.04.10-10-56 <br />
