The fall trapping period was conducted on the evenings of 7-9 October 1987. Trapline
locations are shown on Exhibit 11-3. The following sampling design was used:
Line No. and Type Spacing Number of
Number Habitat of Trap(s) Interval Nights Trapped Dates
1 Rangeland 45-live 15 yds. 3 7-9 October 1987
2 Swale 45-live 15 yds. 3 7-9 October 1987
8 Agriculture 45-live 15 yds. 3 7-9 October 1987
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 = P i i
log P , where,
e
in this report, P i 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 Attachment 11-2.
