SAM .LL MAMMAL STUDIES <br />Small rrsmal species composition, abundance, and habitat association were <br />determined by live trap censusing conducted during Octobpr, 1979.(see <br />Results, page 27). Three loom transects were placed in representative areas <br />of each of the following vegetation types on the study area, <br />1. Upland sagebrush <br />2. Grassland pasture <br />An additional transect was established in a small riparian area on the north- <br />east edge of the study area (Map 11 -1, Appendix A). Two Sherman live traps <br />were placed at each 10m interval along each transect. Traps were baited with <br />a peanut butter, cracked corm, rolled oats,' bacon fat mixture and checked <br />for four consecutive nights. All traps were provided with dacron- -fiber <br />batting to avoid animal loss due to hypothermia. All individuals captured <br />were toe - clipped and recorded according to species, sex, age (juvenile or <br />adult), reproductive status (active or inactive), and location and then <br />released. <br />AVIFAUNA STUDIES <br />cur different components of the avifauna were studied: <br />1. Passerine birds <br />2. Raptorial birds <br />3. Upland game birds <br />4. Waterfowl <br />Four different surveys were undertaken to determine the presence, abundance <br />and production of avifauna on the study area: <br />JUN 1 1 5994, <br />
