We offer the following comments for your <br />consideration. <br />Vegetation at the site is characterized as shortgrass prairie. A prairie <br />dog town is present on-site and represents a portion of a much larger prairie <br />dog complex that extends over numerous adjacent sections of land. Field <br />personnel indicate, however, that this particular prairie dog town may have <br />succumbed to bubonic plague during the summer of 1992 and it may no longer be <br />active. If Federal monies are being used on this project, a black-footed <br />ferret survey may be required. We suggest the applicant contact £F~ie Rig-iona7 <br />office of the U.S. Fish and Wildlife Service in Denver for that <br />determination. <br />Nesting burrowing owls were observed using the site in the summer of <br />1992. Burrows 9-o'~wfs u~'iTize the abandoned prairie dog burrows for nesting <br />and brood rearing activities. We recommend that any surface disturbance <br />avoid that period from April 1st through June 30th, the nesting period for <br />this species. There should be no conflict with nesting burrowing owls if <br />topsoil removal and stockpiling (activities which effectively destroy any <br />prairie dog burrows on-site) takes place either prior to April 1st or after <br />June 30th. <br />The Division appreciates this opportunity to provide input. lease feel <br />free to contact us if additional information is required.,,/,//I~~~~ <br />S erel b16 <br />y S~ c +~' <br />avid ti <br />Wildlife Bi ogis Approved by: /n1 ~ ~`7 ~-~~ <br />Southeast Region R~'nald P.
