Montana Wildlife Research Activities

Much of the Unit research effort from 1970 through the present focused on interactions of predators with both wild and domestic prey species. During a decade when considerable public and scientific opinion held that predators seldom killed healthy wild ungulates or livestock, Unit studies initiated in the 1970�s helped to form the more realistic and useful viewpoint that is still evolving today. Serious economic losses of sheep and lambs to coyotes and golden eagles were documented in several Unit studies, and one study involved developing effective techniques for preventing depredation on lambs and kids by golden eagles. Continuing work on predator-prey interactions has involved demographic effects and life-history tradeoffs involved in nest predation on birds, both game and nongame species, as influenced by altered communities of generalist nest predators, habitat degradation and fragmentation, and other environmental perturbations.
