The United States Fish and <br />wildlife Service (USF1J5) has used this survey method for the past eight years <br />to determine indices of predator abundance in the western United States. <br />• The scent-station visitation technique was developed in New York state by <br />Cook 11949), who suggested that records o£ fox sign at scent posts provided <br />a practical index to the relative abundance of foxes between areas and from <br />year to year. The scent-station visitation tecnnique has been s+arulam3;zed by <br />the Da-iver 'rildlife Research Center (*~~*+~+'t and Knowlton 1973} and has beat <br />used each year since 1972 to survey predators in 17 western states. The results <br />of this program, including statistical analysis, are available from tlg Denver <br />Wildlife Research Center and were crongx~red to data gathered at the project site <br />to determine predator abundance indices. <br />T,he scent-staton visitation tec}vv.que consists of a survey mute corz¢~rised <br />of 50 scent stations, located 0.3 mi. apart. Due to the small area encoaq~as:,ed <br />by the Nucla Mine study area, the number of stations in the predator survey <br />line was reduced to 45. Ttu.s was the maximum number of stations that could be <br />spaced at 0.3 mi intervals traversing all vegetation and topographic types on <br />or within 2 Hiles of the study area.. <br />L <br />_q_ <br />SUN ] ! 1980 <br />I• <br />(Revised July 2006) Attachment 2.04.11-1-16 <br />
