• occurred. Winter aerial counts will also be used to supplement the <br />summer observations. The results of the observations and location <br />of the transect are summarized in Table 8, Wildlife Transect obser- <br />vations and on the Wildlife Observations Map (Map 15). <br />Rodent Studies <br />The purpose of the rodent studies was to determine densities of <br />rodents within the various habitat types on the site. From the <br />data collected, the diversity, density, and the potential influence <br />by rodents on the revegetation program were evaluated. <br />Small mammals (rodents) were sampled using two methods. First, two <br />grids each 120 by 135 (72 traps) were set on two different <br />locations on the site. Grid No. 1 was located in sagebrush-grass <br />habitat type. The conditions at this site were conclusive to a <br />large rodent population. Grid No. 2 was located near the <br />revegetation study plot, the sagebrush-grass-serviceberry type of <br />less quality. The grids were trapped for five consecutive nights <br />using oatmeal as bait in the traps. Rodents trapped were eartagged <br />using Monell No. 1 tags for positive identification and released. <br />• Records of the species, age conditions, sex, trap location and <br />capture - recapture were kept. From these data, species diversity <br />and densities were calculated. This information is set forth in <br />Exhibit 11, Wildlife Information. <br />To supplement data collected from the grids, a 24 station trap <br />transect was located adjacent to each of five browse transects. <br />These transects were trapped for three consecutive nights, each <br />spring and in the fall through the spring of 1976. The transects <br />were designed only to give supplemental data on species diversity <br />and relative abundance within the various habitat types. No <br />absolute numbers or abundance were generated; only an indication of <br />abundance was derived. In addition, 24-station trap transects were <br /> <br />2.04.11-18 <br />
