Natural regeneration of Douglas-fir in uneven-aged stands in southwest Oregon

Creator:: Gerstein, Jared M.
Abstract:: The response to various levels of stand density by natural Douglas-fir regeneration, shrub and sprouting hardwood species was studied in the mixed-evergreen-forests of southwest Oregon. Partial-cut old growth (harvested 22-31 years prior) and thinned evenaged (harvested 9-17 years prior) stand types were used as surrogates for intentionally managed uneven-aged stand...

Buffer strip dynamics in the Western Oregon Cascades

Creator:: Sherwood, Kim
Abstract:: Although buffer strips have long been used as a protection tool when logging near streams, long-term studies investigating buffer strip dynamics are rare. Steinblums et al. (1984) inventoried 40 buffer strips 1 to 15 years old in the western Oregon Cascades beginning in the summer of 1975. Numerous site and...

The relationship of non-recovered rodent caches to the natural regeneration of ponderosa pine

Creator:: Saigo, Barbara Woodworth
Abstract:: Studies were conducted within a 12-mile radius of Camp Sherman, Oregon, in the Deschutes National Forest during the spring and summer of 1965 and the spring of 1966, with one follow-up visit in the summer of 1967. The feeding and foraging activities of Eutamias amoenus and Citellus lateralis were observed,...

Combined Effects of Intensive Forest Management and Microclimate on Reproduction in a Cavity-Nesting Songbird

Creator:: Jones, Kristin N.
Abstract:: Future scenarios of global climate change rely on large-scale climate envelope models that do not account for local climatic conditions to which organisms most closely respond. Shifts in species distributions and phenology driven by climate change are well-documented, yet we lack a strong understanding of how climate change will influence...

Green-tree retention and ectomycorrhiza legacies : the spatial influences of retention trees on mycorrhiza community structure and diversity

Creator:: Stockdale, Christopher A.
Abstract:: These studies are part of the Demonstration of Ecosystem Management Options (DEMO) study, a program researching the effects of different levels and patterns of green-tree retention on ecological, economic, and social phenomena. We restricted our studies to the 15% basal area, evenly dispersed retention treatment. Our objectives were, first, to...

The clonal development of vine maple during Douglas-fir stand development in the Coast Range of Oregon

Creator:: O'Dea, Mary E.
Abstract:: Natural Douglas-fir stand development is the result of many types of disturbance, both natural and management induced. The magnitude and timing of these disturbances have profound effects on the structure and composition of both the overstory and understory plant communities. Vine maple responds to disturbance by basal sprouting, layering, producing...

Revegetation-microhabitat relations in the blast zone of Mount St. Helens

Creator:: Gallant, Alisa L.
Abstract:: The Mount St. Helens eruption of May 18, 1980, offered an excellent setting for evaluating early response of ecosystems to disturbance. Prior to the eruption, the area was densely forested with fir, hemlock, and Douglas-fir, and various understory species. During the course of the eruption, hillslopes within a 180 degree...

Relationships of green-tree retention following timber harvest to forest growth and species composition in the western Cascade Mountains

Creator:: Rose, Coulter R.
Abstract:: National Forest management in the Pacific Northwest is shifting from a focus on commodity production to ecosystem management, in which the health of the entire forest ecosystem is considered, rather than that of a few key species. Ecosystem management includes retention of some live trees following timber harvest (green-tree retention)...
