(Colo sr constrictor) , and Western rattlesnake (Crocalus viridus) have <br />been reported near the study area by local residents. A list of other <br />reptiles and amphibian species that might occur in habitats on or near the <br />study area are provided in Table 1. <br />NVERT cuzRATES <br />Sweep -net samples were collected in grassland pasture and upland sage- <br />brush vegetation on the study area and at a revegetation plot at the Seneca <br />xT mine during June, 1979 to determine abundance of flying insect groups <br />and to ascertain if densities of any groups ray pose a potential proble.-n <br />to revegetation success. The results of this survey are presented in <br />Table 5. The grassland pasture type contained the highest number of <br />insects amenable to collection by the sweep -net method (17.2 insects /m <br />followed by the revegetation site (2.5 insects/m and the upland sage - <br />brush type (1.9 insects /m Also, samples from grassland pasture contained <br />the highest•diversity of insects with 19 groups represented. Plant bugs <br />(Family eUridae) dominated samples from this type, accounting <br />for over 86' of all insects collected. Seed bugs (Family Lyraeidae) was <br />the only other group frequently encountered in grassland pasture and <br />acoaunted for 7.4% of the total density. Plant bugs are considered a <br />serious pest of cultivated plants while seed bugs, so called becauee they, <br />feed mestlly on seeds, are often common on vegetation (grow and 1!hite <br />1970). <br />Plant bugs and seed bugs were also the most common species found ' on the <br />revegetation site but were far less common than on grassland pasture Zvi h <br />only 1.5 and 0.4 insects /m respectively, as compared to 15.1 and 1.3 <br />insects /m , respectively, for grassland pasture. Fewer groups (12) were <br />also recorded in the revegetation area. Stink bugs (Family Pentatomidee) <br />were also fairly common on the revegetation site accounting for almost <br />13% of the total insects collected. Most of the neon r s of this group of <br />bugs are plant feeders, although some are predaceous. A ;ew of the plant <br />feeders occasionally damage cultivated plants, especially fruits. <br />The epp1ne srlee .r sh type crntained the fewest number of insv ---c (1. <br />insects /m and the ;owver ntnri-,er of insi's't orro;ps (11), loaf be, Iles <br />-45- <br />JUN 1 1 1980 <br />
