The weather throughout the trapping periods was clear, mild, and calm with early morning
temperatures reaching near freezing.
All captures were identified before release. Those specimens caught in snap traps and those
that succumbed to hypothermia in live traps were saved as voucher specimens. Results are
reported as number of captures per trap-night. Small mammal species diversity values of each
habitat are calculated after MacArthur (1964) as H = Pi loge Pi, where, in this report, Pi is the
proportion of the number of each species to the total number of captures.
A prairie dog and black-footed ferret survey was conducted in the study area in compliance with
U.S. Fish and Wildlife Service standards and requirements. The survey methods are presented
in Peabody Attachment 11-2.
All observations of mammal species seen during the course of this survey and during the
baseline vegetation survey were recorded in field notebooks and later transferred to a
permanent species account log. With these notes, incidental observations noted during the
ferret survey, small mammal trapping results, the literature survey, and information supplied by
Mr. Ron Arant, an assessment of the mammal fauna of the study area was completed.
Birds. Bird species were sampled by a variety of techniques. Observations (either incidental or
concurrent with surveying activities) indicating breeding, significant migratory behavior, and
