4-51 <br />4.6.6 Reptiles and Amphibians <br />• The lease area does not represent an important area in <br />terms of habitat for reptiles and amphibians. Only three <br />species were identified; the northern plateau lizard, <br />Secloporus Undulatus; the collared lizard, Crotophytus <br />Collaris; and the desert short-horned lizard, Phrynosoma <br />Douglassi. None of these species were numerous at sites <br />where they were observed. <br />4.6.7 Aquatic Resources <br />There are no acuatic resources within the boundaries of / <br />the lease area or the permit area that would support per- `/ <br />manent fish populations. East Salt Creek and its tribu- <br />• taries in these upstream areas remain dry much of the year. <br />4.6.8 Threatened and Endangered Species <br />The peregrine falcon could occur within the boundaries <br />of the lease area. No sightings were made during field <br />trips, however, and we know of no reports of these birds <br />for the immediate area. It is possible that the peregrine <br />falcon could be present for brief periods during migration, <br />and it is possible that this species nests among the rim- <br />rock habitat which is widespread in the area. <br />The bald eagle, a recently designated endangered species, <br />is likely to occur within the boundaries of the lease area, <br />. especially for brief periods during the winter period. Dlone <br />were observed within the lease boundaries during the field <br />
