Dynamics of wolves and their prey in Denali National Park, Alaska. Management of wolves and their prey, is currently a major national environmental issue with recovery of threatened and endangered wolf populations in the western U.S. In Alaska, the contentious wolf management debate continues, and federal land managers are playing a larger role in traditional wildlife management because of subsistence management responsibilities. The wolf/prey system in Denali National Park and Preserve provides a unique opportunity to gain basic understanding in the natural dynamics of wolves and ungulates to aid in these national and regional management issues. The objective of this research is to determine the population dynamics of wolves and their major prey species, caribou and moose, in sufficient detail to evaluate the interrelationships between species and to investigate the effects of weather and differential landscape use on predator/prey relationships.
