<br /> BIOTIC COMMUNITIES <br />A summary of the Distribution of the Biota in the Zonal Biotic <br />Communities of the study area follows. Communities are grouped as <br />desert and hydric-acquatic communities. Transzonal communities are not <br />considered since they pass through two or more of the zonal communities. <br /> Desert Hydric-A'Iuatic <br /> Communities Communities <br />Biota CR Bl Total DS SR St La Total <br />Vascular Plants 256 185 311 21 36 3 0 50 <br /> '" <br />Fish 0 0 0 20 0 21 17 41 <br />Amphibians 0 0 0 7 7 7 3 9 <br />Reptiles (total) 30 19 30 0 14 1 0 15 <br />Turtles 1 1 1 0 0 1 0 1 '.: <br />Lizards 14 13 14 0 7 0 0 7 <br />Snakes 15 5 15 0 7 0 0 7 <br />Birds (total) 33 26 40 202 159 15 44 245 <br />Permanaent residents 8 6 9 22 18 0 2 26 <br />Summer residents 6 8 11 19 20 3 0 28 ." <br />Winter residents 10 7 10 65 40 7 27 71 <br />Non-residents 9 5 10 107 87 5 16 139 <br />Manunals (total) 44 33 48 26 37 7 2 45 <br />Insectivores 0 0 0 0 0 0 0 1 <br />Bats 14 6 14 6 9 6 0 9 x <br />Rodents 16 14 18 10 18 1 1 19 <br />Lagomorphs 2 2 2 2 2 0 0 2 <br />Carnivores 9 6 9 4 6 0 1 9 <br />Ungulates 3 5 5 4 2 0 0 5 <br />Totals 363 263 429 276 253 54 70 405 ~ <br />Code letters for the biotic communities are: Cr - creosote bush, B1 - <br />b1ackbrush, DS - desert spring and marsh, SR - stream riparian, ST - <br />stream, La - lake (Bradley and Deacon, 1967). <br />Source: Clark County 208 Environmental Report No.2, Land Development <br />Suitability Analysis, Table 16, page 56. ." <br /> <br />C-2 <br /> <br />UUl:J58 <br />
