It would be expected that this trend toward development and loss of habitat would continue indefinitely. IMPACTS OF ALTERNATIVE 1 ACTION NO Bison with gray wolf Mattson and Knight (1992) concluded that the reintroduction of wolves to the area would likely have both positive and negative effects on grizzly bears. Slight reductions in populations of elk and bison would be probable, and interior herds may be most affected. Big game populations could become more stable allowing for a more stable supply of carrion. Elk would likely be more affected by wolves than bison. Interactions among predators would be likely, with wolves perhaps reducing coyote popula- tions and perhaps reducing competition for carcasses. Bears should be able to displace individual wolves from kills, but might not be able to displace larger groups of wolves. Overall, the issue of how wolves and grizzly bears would interact on the biomass available in terms of prey and carrion would be uncertain. Competition for carrion in the spring between bears and wolves is likely (Servheen and Knight 1990). The most serious threat to threatened and endangered species would be private land development and the concomitant increase in interactions between humans and these species. In the last 5 to 10 years, development has increased dramatically on private land near Yellowstone National Park. The particular areas experiencing this increase are the Yellowstone River valley (or Paradise Valley) north of Gardiner, the area in and around Gardiner, and the West Yel
