Those specimens caught in snap traps and those that <br />succumbed to hypothermia in live traps were saved as voucher specimens. Results are reported <br />as number of captures per trap-night. Small mammal species diversity values of each habitat are <br />calculated after MacArthur (1964) as H = Pi loge Pi, where, in this report, Pi is the proportion of <br />the number of each species to the total number of captures. <br />A prairie dog and black-footed ferret survey was conducted in the study area in compliance with <br />U.S. Fish and Wildlife Service standards and requirements. The survey methods are presented <br />in Peabody Attachment 11-2. <br />All observations of mammal species seen during the course of this survey and during the baseline <br />vegetation survey were recorded in field notebooks and later transferred to a permanent species <br />account log. With these notes, incidental observations noted during the ferret survey, small <br />mammal trapping results, the literature survey, and information supplied by Mr. Ron Arant, an <br />assessment of the mammal fauna of the study area was completed. <br />(Revised March 2006) 2.04.11-12 <br />
