At each station, a small perforated plastic capsule containing about 1 gram <br /> of a synthetic attractant (supplied by U. S. Fish and Wildlife Service, <br /> Pocatello, Idaho) was positioned at the center of a circle of sifted earth <br /> 3 Et in diameter. The capsule was supported two inches above the ground by <br /> a small wooden stick. Stations were placed adjacent to the road edge <br /> and alternated from left to right sides of the road to reduce the influence <br /> of wind direction. The survey route was checked daily for four consecutive <br /> days. Animal visits based on tracks were recorded for each station on a <br /> standard field data form. <br /> Mamralian predator sightings and sign were recorded on standard wildlife <br /> observation forms during all other field activities. All sightings or sign <br /> were recorded by species, location, and habitat type. <br /> I ERPEI'OFALNA <br /> Reptiles noted during sunmer_ suzveys were recorded according to species, locution <br /> and macro and micro-habitat type. Potential amphibian breeding sites (ponds, <br /> streams, etc.) were visited during two nights in May, 1979 to detexudne the <br /> species and abundance of anphibians utilizing the study area (see Results, <br /> page 44) . <br /> ANDIAL DISTRIBL'rION STUDIES AND DOCUINIENTATION OF ANIMAL PRESF_NCE <br /> Animal distribution on the study area was deterndned on the basis of a com- <br /> pilation of wildlife observation data obtained during field investigations <br /> and from previous data obtained by the DOW, Peabody Coal Company, and others. <br /> Compiled information was plotted on study area maps to depict the distribution <br /> of the following important wildlife groups: <br /> 1. Mule deer <br /> 2. Raptors and raptor nest sites <br /> 3. Waterfowl <br /> 4. Upland game birds <br /> 5. 1%lamalian predators <br /> -10- <br /> JUM ! ! Iwo <br />
