Characterization of fire effects on forest ecosystems in the Tillamook Forest, Oregon

Creator:: Chen, Shu-Huei
Abstract:: From the 1920's through 1951 several severe fires occurred in the predominantly conifer forest ecosystems of the northern Oregon Coast Range. Of the 211,151 ha. of mapped area, 57 percent was burned. The effects of frequent fires with high severity on forest ecosystems over time at the landscape level is...

Hydrology and delineation in four wetlands in the Oregon Cascades

Creator:: MacLeod, Norman A.
Abstract:: Four wetland sites were identified and delineated in Silver Falls State Park, Oregon using procedures outlined in the 1989 Federal Manual for the Identification and Delineation of Jurisdictional Wetlands and subsequently monitored for a ten month period. A network of 225 shallow (32") wells was installed throughout the sites to...

A preliminary classification of forest communities in the central portion of the western Cascades in Oregon

Creator:: Dyrness, C. T., Franklin, Jerry F., Moir, William H., and U.S. International Biological Program. Coniferous Forest Biome
Abstract:: Forest communities in the central portion of Oregon's western Cascades are arrayed along moisture and temperature gradients. With the aid of reconnaissance data and a computerized ordination technique, 23 forest communities have been provisionally recognized in two distinct forest zones, the Tsuga heterophylla (300 to 1050 m in elevation) and...

An evaluation of understory vegetation dynamics, ecosystem resilience and state and transition ecological theory in an eastern Oregon ponderosa pine forest

Creator:: Carr, Craig A.
Abstract:: Relatively recent increases in ponderosa pine abundance have effected unprecedented changes to ecosystem structure and function. Efforts to restore ponderosa pine systems are often focused on the manipulation of tree structure and the re-introduction of a more natural fire regime. Successful restoration should also incorporate understory components but information addressing...

Tree species-soils relationships in old-growth forests of the Oregon Coast Range

Creator:: Cross, Alison
Abstract:: Tree species directly and indirectly affect soil nutrient cycles. I sought to characterize soils and foliage associated with four common canopy tree species (Douglas-fir, western hemlock, western redcedar, and bigleaf maple) in mixed-species old-growth forests of the Oregon Coast Range and to determine whether and how soils differ among the...

Patterns in understory vegetation communities across canopy gaps in young, Douglas-fir forests of western Oregon

Creator:: Fahey, Robert T.
Abstract:: Canopy gap formation is a major factor contributing to maintenance of overstory species diversity and stand structure in forests and may be integral to development of understory shrub and herb layers as well. Acknowledgement of gap formation as a fundamental feature of natural forests has led to consideration of gaps...

Validating songbird habitat relationship models

Creator:: Wilson, Dorothy G.
Abstract:: Models are commonly used to assess and predict wildlife response to management practices. Model validation is essential if managers are to use them with confidence. Fifteen forest bird-habitat relationship models were developed by biologists using data collected from private forestland in southwest Washington. These models predict species' probability of occurring...

Modeling water uptake on coniferous forest Oregon watershed 10 synthesis

Creator:: Waring, Richard H., Running, S. W., Holbo, Harold Richard, Kline, J. R., U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: In the Coniferous Forest Biome, many of the understory as well as dominant plants are evergreen and thus water uptake is a year around process. The flow of water from the soil through plants to the atmosphere affects the entire forest ecosystem. As water is evaporated, it absorbs heat and...

Identification and characterization of forest communities and habitat types in and adjacent to the H. J. Andrews Experimental Forest

Creator:: Dyrness, C. T., Franklin, Jerry F., Zobel, Donald B., U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: A total of 23 forest communities have been identified and characterized in a preliminary manner. Data used in formulating the classification had previously been collected on 300 reconnaissance plots located on the H. J. Andrews Forest and surrounding area. Vegetation classification was facilitated by similarity analysis and stand ordination procedures...
