ranging, and it is possible that individuals might move through or reoccupy the region at some point in <br />time. <br />Based on comments received from the U.S. Fish and Wildlife Service (USFWS) in October 1998, SCC <br />committed to conducting a boreal toad survey in the spring of 1999. PRES contacted both the UDFWS <br />and CDOW to discuss the acceptable survey methodology and scheduling of the survey. Three separate <br />surveys were conducted: the first in late -April, the second in mid-May, and the last in early -June. The <br />three surveys, plus a nocturnal search, yielded no evidence of boreal toad presence on the nearby IIW <br />South Expansion area. <br />Reptiles and Amphibians. The amphibian and reptile species which have been observed on the Seneca II - <br />W study area are included in Table 11-13 along with a list of those species which could occur on the study <br />area according to preferred habitat and species distribution. Several large prairie rattlesnakes (Crotalus <br />viridis) have been road -killed on County Road 53 along Dry Creek throughout the 1979 summer field <br />period. A small rattlesnake was observed on a sagebrush covered knoll near big game pellet group <br />transect PG -1 during the August 1979 pellet group plot inspection. A northern sagebrush lizard <br />(Sceloporus graciosus) was observed in sagebrush habitat. Other reptiles and amphibians sighted on the <br />study area were observed near streams or gully bottoms. <br />Invertebrates. Results of the insect sweep sampling are given in Tables 11-14 through 11-18. Relative <br />diversity of the invertebrate population and total numbers captured at each sampling site are presented <br />within these tables. Diversity of insect groups was the highest at Site 1 (forb vegetation) with total <br />numbers being relatively high also. Abundant families at this site included Curculionide (snout beetles) of <br />the order Coleoptera (45 percent of the total numbers). The sedge meadow (Site 2) sample contained <br />Cercopidae (frog hoppers) of the order Homoptera, comprising 22 percent of the total numbers, with <br />Miridae (plant bugs) and Lygaridae (seed bugs) of the order Himpitera making up 20 and 42 percent of the <br />total numbers, respectively. Curculionidae was the most abundant family in the sagebrush type at site 3 <br />with 48 percent of the total numbers. Formicidae (ants) of the order Hymenoptera comprised an <br />additional 20 percent of the insect population. Site 4 (forb vegetation) had Tephritidae as the most <br />abundant family with 53 percent of the total numbers. All site locations are depicted on Exhibit 11-3. <br />Data from the May 1974 samples are indicative of insect populations on grazed rangeland. The following <br />discussion is a short description of the major insect families occurring on the study area. Curculionidae <br />are almost exclusively phytophagous. The larvae attack all plant parts and usually live within the plant <br />MT 18-07 24a 08/20/18 <br />
