File No. M-2000-016 Dear Mr. Mount: III IIIIIIIIIIIIIIII sss For ~!Jlifi- For Ptoplr The following corutitute the conuttertts of the Colorado Division of Wildlilie. Mike Sherman (Field Habitat Biobbrist) have reviewed this Rtxlametion Permit Application Consideration and made a field visit to the proposed amended t-mte site on Apri126, 2000, and was accompanied by Pam Acre from Tuttle Applegate, Inc. We highly reconrmettd that the applicant maintain a mutimturt 200 foot setback from the South Platte River and even rrore pret'etabie would be that the applicant tttauttain this setback from the edge of the riparian area abng the River. Abng the River ate willows and old and large cottonwood trees. We highly recommend that aU of these trees and the downfall be allowed to remain statding and intact on the site after the proposed project's cort>pletion. These trees provide vahrable wildlife habitat on the site including peaches for roosting raptors and cover for deer, rabbits, fox, wyote, skunks, tatcooq and reptiles. Ahhotrgh there is no evidence of raptors nesting directly on the proposed mining srte (no nests currently observed), ntmterous raptor species may potentia{ly nest in the cottonwood trees found on the property. Nou that the tnmutg site is within a designated Winter Range of Bald Eagle, lured as Federally Threatenod, and u within the overall range of the Great Blue Heron which breeds end feeds abng the South Platte River. We observed an active black-tarred prairie dog town on the site. We reeommerd that the prarie dogs be eiit}rer moved alive to another location or htrtttanely killed before any earth-moving occurs. Since Western Btttrowutg Owls use prairie dog towers and live in prartie dog holes, the following shotild be observed: - [f con9trvetion is to ocetu between March (and October 31, the area should be checked for the prt;sence of btmowirtg owls prior to any earth-rmving taking place. The owls are sttsceptibk to being btnied and killed in their holes by wnstruclion activity doming the nesting season. - if cottsauction is done between November l end February 28, a is very tmhlcely that owls wouli be presera since they migrate out of the state dtuing the winter.
