Abstract:: I studied bird and rodent nesting in woodpecker-excavated cavities in pifion-juniper (Pinus edulis-Juniperus monosperma) (P-J) woodland in southeastern Colorado during the spring and summer of 1987 and 1988. Two related investigations were conducted: one described characteristics of habitat used by birds and rodents nesting in woodpecker-excavated cavities and the other...

Abstract:: Green-tree retention is being implemented on state and federal lands in Oregon. Silvicultural prescriptions with tree and snag retention are thought to mimic natural disturbance patterns in the Pacific Northwest more closely than traditional silvicultural practices, which reduce structural complexity. The effects of green-tree retention on native bird species in...

Abstract:: Previous studies of bird communities in the mid-Willamette Valley, Oregon, indicated that Oregon white oak (Ouercus garryana) stands supported more cavity-using bird species than sympatric stands of Douglas-fir (Pseudotsuga menziesii). Mature Oregon oak stands are being harvested and few are regenerating. I compared cavity availability for hole-using fauna among 10...

Abstract:: The effect of snag retention on clearcuts on breeding bird populations was evaluated in the Douglas-fir (Pseudotsuga menziesii) dominated forest in central coastal Oregon. Diurnal bird species on 14 clearcut sites (< 4 years old) were censused during two breeding seasons. On clearcuts containing high numbers of snags, cavity-nesting birds...
