In addition to The available literature personal concocts with Jim Hicks, Bill <br />• Clark and Clait Braun of The Colorado pivision of Wildlife were made to collect <br />unpublished historical and site specific data for the area. <br />Terrestrial Wildlife - Data Collection <br />Several techniques were used to quantify spatial and seasonal distribution of <br />terrestrial vertebrates on the Edna Mine Complex; aerial and ground transecis for <br />deer and elk as well as other large mammals, lek and breeding area counts, brood <br />routes, ground and aerial transecis for grouse, flushing tronsects for all diurnal <br />species (E mien 1971) and line and grid trapping for nocturnal rodents (Anderson <br />1975). <br />In addition to the quantiative sampling, opportunistic surveys were made That <br />encompassed areas both on and around the permit area. The limits of The study area <br />as well as iransect and grid locations are shown on Exhibit 2.7-20. These <br />opportunistic surveys included aerial and ground searches for the active and inactive <br />raptor nests, threatened and endangered species and big game. These, as well as <br />other species encountered during the surveys were recorded by location and habitat <br />• type. <br />Big Game - seasonal habitat use by deer and elk was determined using <br />aerial tronsects and supplemented with data from flush tronsects and opportunistic <br />observations. Aerial tronsects were flown from November 1979 through early June <br />1980. Migration routes (if any) and winter use areas were identified during flights <br />mode (at least once per month) from late November through April. Early morning <br />flights were mode in late May and early June to estimate numbers of cow elk using <br />known calving areas and does using known fawning areas. In addition, attempts were <br />made to locate suspected calving and fawning areas on or near the property that had <br />not been previously recorded. <br />Upland Game Birds - The three species of grouse which occur on and <br />around the Edna Complex (Columbian sharp-tailed, sage and blue) were evaluated <br />using lek and breeding area counts in the spring, brood routes in The summer, activity <br />routes in the late summer and fall, aerial transecis in the winter (to establish an <br />indication of winter habitat use), flushing iransect data and opportunistic ob- <br />servations. <br />In addition to the techniques previously outlined, a special study utilizing radio <br />. telemetry was initiated in the fall of 1979 to evaluate the Columbian sharp-tailed <br />2.7-70 <br />
