!~ecarnber 1, 2Q33 Appendix ra Pafie tl-o <br />Lynx occupancy levels in the West Elks are not well known, but the species has not been <br />scientifically documented on the proposed lease tract. In the recent past, the CDOW has located <br />two adult radio-collared lynx in the vicinity: an individual on the Grand Mesa, and an individual <br />moving east along the base of the Ragged Mountains (Broderdorp 2003). <br />USFS, BLM, and USFWS have delineated areas of suitable habitat for lynx. The proposed lease <br />lies within the Mount Gunnison Lynx Analysis Unit (LAU), the agencies mapped primary denning <br />habitat at subalpine and higher montane elevations in spruce-fir and mixed conifer forests, and <br />"other' habitat (capable but not currently denning or winter forage habitat) in aspen stands mixed <br />or significantly interspersed with spruce, fir, or Douglas-fir (LeFevre 2003, USES 2002, CNHP <br />2002). <br />Roughly 40% of the lease area is mapped as lynx habitat. Winter habitat occurs in small patches <br />in surrounding areas, and one small patch barely enters the lease area. Denning habitat and <br />"other' habitat is mapped in several forest patches separated by mountain shrub-dominated <br />areas. <br />ron Coal Lease/ Gyinx Habitat Areas:" <br />13 <br />24 <br />".

During the early nineties, on nearby leases, Mountain Coat Company monitored the <br />subsidence effects on Cooper's hawk nests in aspen groves at approximately 7,000 feet in <br />elevation. Cooper's hawk nests were located in areas with overburden depths of 375 to 520 feet. <br />No damage or loss of aspen trees was detected during monitoring of the subsidence related <br />Envn ~.nntertai ,~ssc5~,nent <br />~(HSi i'13i1(C;."i )_~t1 I rcCt <br />Gu~~risr~n t:ounty, C~;lorado <br />• <br /> <br />ht ~`~ ~_;,;ti <br />iFS=~~~~~' ::3 <br />ISFS.: -~ - --'- <br />tF~._ . <br />• <br />
