Biological Assessment for DMG Permit Renewals McClave Canyon & Munger Canyon Mines <br />• ~ Not Likely to Adversely Affect <br />The following species potentially occur in the assessment areas. Based on the marginal <br />suitability of habitat in the assessment areas, the limited availability of suitable habitat in the <br />assessment areas, the relatively small area of pre-existing surface disturbance in the <br />assessment areas, or the limited occupancy of the region by the species, the proposed actions <br />may effect, but are not likely to adversely affect <br />• Big free-tailed bat (Nyctinomops macrotis) <br />• Ferruginous hawk (Buteo regalis) <br />• Fringed myotis (Myotis thysanodes) <br />• Great Basin spadefoot (Spea infermontanus) <br />• Longnose leopard lizard (Gambelia wislizeni~) <br />• Midget-faded rattlesnake (Crotalus viridis concolor) <br />• Milk snake (Lampropeltis triangulum) <br />• Northem leopard frog (Rana pipiens). <br />• Northem pocket gopher (Thomomys talpoides) <br />• Spotted bat (Euderma maculatum) <br />• Townsend's big-eared bat (Plecotus townsendii) <br />• Yellow-billed cuckoo (Coccyzus americanus) <br />• Yuma myotis (Myotis yumanensis) <br />8 REFERENCES <br />~!
