The scent-station visitation technique was developed in New York state <br />• by Cook (1949), who suggested that records of fox sign at scent posts pro- <br />vided a practical index to the relative abundance of foxes between areas and <br />from year to year. The scent-station visitation technique has been s}~~~~*~ized <br />by the Denver Wildlife Research Center (T.inhar+ and Krnowlton, 1973) and has <br />been used each year since 1972 to survey predators in 17 western states. The <br />results of this program, including statistical analysis, are available from <br />the Deirver Wildlife Reseazch Center and were arnpared to data gathered at the <br />project site to detar,,,;,w predator abundance indices. <br />One mammalian predator survey line consisting of 46 stations was placed on <br />the project azea. The s+an~a,-~ technique as implanented by the U.S. Fish <br />and Wildlife Service (T.inharh and Knowlton, 1973) utilizes 50 stations along <br />a 15 mile mute. The small size of the Seneca II Mine site did not provide <br />15 miles of road; therefore, only 46 stations could be sampled. All stations <br />were spaced at 0.3 mi. intervals along a 13.8 mile mute traversing all vege- <br />tation and topographic types on or adjacent to the permit azea (predators may <br />• cover a wide area in their seazch for food). At each station, a small per- <br />forated plastic capsule containing about 1 gram of a synthetic attractant <br />(supplied by U.S. Fish and Wildlife Service, Pocatello, Idaho) was positioned <br />at the center of a circle of sifted earth 3 ft. in diameter. The capsule was <br />supported two inches above the ground by a small wooden stick. Stations were <br />placed adjacent to the road edge and alternated from left to right sides of <br />the road to reduce the influence of wind direction. The survey mute was <br />checked daily for four oonsecvtive days. Animal visits based on tracks were <br />recorded for each station on a standard field data form. <br />Mammalian predator sightings and sign were recorded on standard .wildlife <br />observation forms during all other aerial and ground field activities. All <br />sightings or sign were recorded by species, location and habitat type. <br />HERPEigFAUNA <br />Reptiles Hated during sumnes surveys were recorded acwrding to species, loca- <br />. tion and macro and micnrhabitat type. Potential amphibian breeding sites <br />(ponds, streams, etc.) were visited during two nights in May, 1979 to deter- <br />mine the species and aln?n~~nce of amphibians utilizing the project site. <br />-13- <br />Revised 5-27-81 <br />
