Old-growth Douglas-fir forests in the Pacific Northwest - and their most celebrated inhabitant, the northern spotted owl - have engendered an acrimonious controversy that has been raging for over a decade. Should ancient forests be protected for their aesthetic appeal and because they provide a broad range of ecological values, including the most amenable environment for some. 5 Wildlife Habitat Relationships in Unmanaged Douglas-Fir Forests: A Program of Research by Leonard F.

The fire history of Pacific Northwest Douglas-fir forests is varied and complex because Douglas-fir exists in a variety of forest types over a wide range of environments. Douglas-fir has been dominant over this region because of disturbance by fire and the species' adaptations to fire. Human-caused fires have been locally important, but lightning appears to . My previous field studies have included community studies of amphibians and small mammals in unmanaged Douglas-fir forests, radiotelemetry studies of the pileated woodpecker in coastal forests of Washington and the fisher in the Cascade Range of southern Oregon, snow-tracking studies of the Canada lynx in the North Cascades of Washington, and a.
