and Whitman 2000a, Hayes et al. 2002). Roads invite human activity of all sorts, and can<br />

lead to poaching, over-hunting and over-fishing (Strittholt etal. 2006). Elk vulnerability<br />

is highest in areas with open roads, reduced in areas with closed roads, and lowest in<br />

roadless areas. Watson (2005) <strong>report</strong>ed that roads facilitate poaching of pronghorn.<br />

Localized 6 th code watersheds with higher road densities will continue to maintain higher<br />

exposure rates between humans and wild ungulates facilitating the potential for additional<br />

harvest of these species. Alternatives that maintain higher road densities levels will<br />

continue to facilitate this exposure; Table 107 identifies the alternatives of concern in<br />

dark grey. These localized areas of higher road densities would not cause a significant<br />

effect to wild ungulates on the Gila National Forest.<br />

Carnivores: Claar et al. (1999) documents that research related to recreational impacts<br />

on carnivores are lacking. They go on to state that increased access into remote habitats<br />

is a concern, particularly to carnivore species that usually seek secluded areas. Claar et<br />

al. (1999), state that wolves are habitat generalists and are a very resilient species that can<br />

coexist with people if they are tolerated by humans. They are an intelligent species,<br />

which allows individuals to adapt to different levels of disturbance. Individuals may be<br />

very sensitive to human disturbance, but others tolerate disturbance. These traits between<br />

different individuals make it difficult to evaluate the overall affects of recreational<br />

activities (Claar et al. 1999). Much of the literature shows a strong negative relationship<br />

between wolves and increased road densities (Claar et al. 1999, Thiel 1985, and Mech et<br />

al. 1988). Researchers have found that when road densities exceed about 1 mile/mi² (1.6<br />

km/0.9 km radius circle) wolves were displaced or avoided the area (Mech et al. 1988<br />

and 1985). However, Claar et al. (1999) states that findings from many of these studies<br />

that looked at large well established wolf populations may not be applicable to<br />

fragmented, recovering populations in western states. Wolf populations in Wisconsin,<br />

Minnesota, and Montana have become more habituated to humans through time since<br />

recolonization has occurred in these recovering populations (Claar et al. 1999, and Thiel<br />

et al. 1998).<br />

The Mexican Wolf Reintroduction EIS did not recognize road densities on the Gila<br />

National Forest as problem; however since the start of the reintroduction project in 1998,<br />

within the recovery area in Arizona and New Mexico illegal shootings and vehicle<br />

collisions have been the greatest source of wolf mortality. Of the 68 wolf deaths,<br />

between 1998 and June 1, 2009, 31 are associated with shooting and 12 with vehicle<br />

collision (U.S. Fish and <strong>Wildlife</strong> Service 2010).<br />

Localized 6 th code watersheds with higher road densities will continue to maintain higher<br />

exposure rates between humans and wide ranging carnivores facilitating the potential for<br />

additional harvest of these species. Alternatives that maintain higher road densities levels<br />

will continue to facilitate this exposure; Table 107 identifies the alternatives of concern in<br />

dark gray. The potential to adversely affect wild ranging carnivores like the wolf would<br />

be expected to continue under the alternatives that maintain higher road densities in the<br />

localized areas, as identified in Table 107.<br />
