season timing for raptors in the Roan Plateau region (Andrews and Righter 1992, Kingery 1998). <br />These recommendations are summarized in Table 10. <br />Table 10. Timing and buffer recommendations (guidelines) for active raptor nests. <br />Species <br />Buffer Zone <br />Seasonal Restriction <br />American Kestrel <br />Bald Eagle <br />0.50 mile <br />15 October — 31 Jul <br />Cooper's Hawk <br />0.25 mile <br />1 April —15 August <br />Golden Eagle <br />0.50 mile <br />15 December —15 Jul <br />Great Horned Owl <br />Long-eared Owl <br />0.25 mile <br />1 March - 15 Jul <br />Northern Harrier <br />0.25 mile <br />1 April —15 August <br />Osprey <br />0.25 mile <br />1 April — 31 August <br />Peregrine Falcon <br />0.50 mile <br />15 March — 31 Jul <br />Prairie Falcon <br />0.50 mile <br />15 March —15 Jul <br />Red - tailed Hawk <br />0.33 mile <br />15 February - 15 Jul <br />Sharp-shinned Hawk <br />0.25 mile <br />1 April —15 August <br />Swainson's Hawk <br />0.25 mile <br />1 April - 15 Jul <br />* Great Homed Owls and Kestrels are relatively tolerant of human activity. Keep activity to a minimum during breeding season. <br />5.2.3 Waterfowl: Maintaining or enhancing the riparian corridor and the Loma Drain wetland <br />would secure the habitat for waterfowl use. A noxious weed management plan to control <br />whitetop and other weeds including lambsquarter would enhance the riparian corridor, provide <br />additional forage, and cover for waterfowl. Tamarisk control projects may potentially enhance <br />nesting habitat for waterfowl by increasing riparian grass habitat. Controlling erosion would <br />maintain the large meanders in Reed Wash that provide backwaters that are important resting <br />areas for waterfowl. <br />5.3 REPTILES <br />Reptiles occurring in the project area may be preserved by maintaining and improving natural <br />vegetation in surrounding habitat. Successful interim vegetation reclamation and minimizing <br />removal of natural vegetation as part of other wildlife protection measures help protect reptiles. <br />5.4 AMPHIBIANS <br />Protecting and enhancing the vegetation in the riparian corridor along Reed Wash would <br />maintain existing amphibian populations. Tamarisk control would provide opportunity for <br />regrowth of native vegetation. Control of noxious weeds along the wash banks may allow for <br />growth of species such as coyote willow, common reed, rushes and sedges that provide cover <br />and foraging habitat for amphibian species. <br />5.5 AQUATIC RESOURCES <br />5.5.1 Fish: The physical alignment of Reed Wash is not designed to be affected by project <br />construction or operation. The spur line will cross Reed Wash with a bridge that will span the <br />aquatic environment (Figure 1). Therefore, there will be no structures that will affect the <br />26 <br />
