Old-growth forests, Terrestrail ecology
Much of ecology, especially terrestrial ecology, studies how a given system changes over time. Pressures from preservationists and demands for timber products have focused ecological attention on Pacific Northwest forest ecosystems, and much of the debate has been over how change affects "old-growth” forests. Old-growth forests have a number of distinguishing characteristics including species composition, size of trees and forest structure that make them unique (Waring and Franklin 1979, Franklin et al. 1981). Old-growth forests west of the Cascade mountain range are dominated by Douglas fir (Psuedotsuga menziesii) and western hemlock (Tsuga heterophylla) trees approximately 200-750 years old. The climax community consists of the shade tolerant western red cedar (Thuja plicata) and western hemlock species that grow up in the understory and gradually phase out Douglas fir (Waring and Franklin 1979; Franklin, et al. 1981).
