The lectureship will focus on current and emerging developments in the area of forest soils, with emphasis on science, technology, and educational or policy issues. The lecture is generally be given as a plenary session sponsored by the Forest, Range and Wildland Soils Division. The following are representative of variability in properties of forest soils, complied for the forest soils of the Douglas fir region of northern California, Oregon (Figure 2), Washington, and southwestern British Columbia: soil depths, 1– m; nitrogen contained in forest floors, – kg ha −1; total N in soils, –22 kg ha. The Sister Rocks Research Natural Area has been used as a sampling site for studies of subalpine forests and soils in the southern Washington Cascade Range (Franklin ) and for a study of characteristics and distribution of Recent pumice and ash falls.4 This natural area is particularly valuable as a.

The OSU Research Forests were donated to the College of Forestry to serve as a living laboratory and outdoor classroom for students, researchers and managers to learn about forest ecosystems and management. OSU utilizes the Research Forests to find new ways to sustainably manage forests for conservation, education, business and recreation. At other sites in the central Cascades, recent research has addressed the ecology and dynamics of forest-meadow mosaics, changes in the aerial extent of meadow openings, the history of human use of meadows, the influence of volcanic deposits in forest and meadow soils of the western Cascades, and biogeochemical changes in soil properties across forest-meadow .

The Oregon Coast Range is a useful place to study this since it experiences strong forcings – storms, earthquakes, fires, and human land use. By studying sediments of lakes in this steep, dissected mountain range, we can capture a record of river basin events and an expression of their associated delivery mechanisms, as well as relative and.
