Genesis of some soils in the central western Cascades of Oregon

Creator:: Brown, R. B.
Abstract:: Soils representative of several landscape units in the H. J. Andrews Experimental Forest, Western Cascade Range, were sampled, analyzed, and tentatively classified. Genetic inferences were drawn relating soils to landscape position and other factors of soil formation. Descriptive information and nutrient capital data were provided to support ecosystem modelling efforts...

Comparative rates of CO₂ production from the forest floor in the Douglas-fir ecosystem

Creator:: Phillips, Michael John
Abstract:: To obtain data on the decomposition of the forest floor, a battery operated electrolytic respirometer was developed making it possible to measure CO₂ evolution from field moist forest floor samples in situ independent of root respiration. Banks of four respirometers powered by two 12-volt batteries were installed in three old...

Cation exchange properties of forest litter as influenced by vegetation type and decomposition

Creator:: Warner, Susan Ann
Abstract:: Decomposition of forest litter is a complex process involving interactions between physical, chemical and biological factors. As litter decomposes it is chemically altered. Cation exchange capacities of litter represent a means of characterizing the number of hydrophilic acid groups. Some kind of soil-root ion exchange mechanisms are utilized by the...

Impact of landslide erosion on tree growth and vegetation in the western Oregon Cascades

Creator:: Miles, Donald William Riggs
Abstract:: Shallow, rapid soil mass movements are common events and primary sources of sediment in steep terrain of the Pacific Northwest. Poorly vegetated debris deposits and scars resulting from landslides remove land from the productive timber base, and are subject to continuing erosion. To examine the impact of these events on...

Nitrogen, phosphorus and particulate matter budgets of five coniferous forest ecosystems in the western Cascades Range, Oregon.

Creator:: Fredriksen, R. L.
Abstract:: Nutrient and particulate matter balances were established for five ecosystems dominated by Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] in the western Cascades, Oregon. Carriers of N and P were particulate matter (dust in precipitation and sediment in streams) and dissolved matter in both precipitation and stream water. The input and outflow...
