Forest Soils and Topography : Decoding the Influence of Physical Site Characteristics on Soil Water and Forest Productivity in Oregon's Coast Ranges

Creator:: Rodman, Henry
Abstract:: Forest soils and topography have long been known to influence forest productivity in complex terrain such as Oregon’s Coast Ranges. Incorporating physical site characteristics into predictions of forest growth and yield, however, has been problematic because of the high spatial variability of soil properties and the challenges associated with representing...

Post-harvest establishment influences ANPP, soil C and DOC export in complex mountainous terrain

Creator:: Peterson, Fox S.
Abstract:: The link between aboveground net primary productivity (ANPP) and resource gradients generated by complex terrain (solar radiation, nutrients, and moisture) has been established in the literature. Belowground ecosystem stocks and functions, such as soil organic carbon (SOC), dissolved organic carbon (DOC), and belowground productivity have also been related to the...

Identifying site characteristics that explain variation in Douglas-fir site productivity and stem form

Creator:: Magalska, Lauren E.
Abstract:: Foresters care about site productivity and stem quality in Douglas-fir plantations for many reasons. The profitability of forest land and the economic returns on silvicultural investments are directly related to site productivity. Thus, understanding the relationships among Douglas-fir productivity, stem form and site characteristics is important economically. My objective was...

Temporal effect of vegetation management on growth and wood quality of conifers in a western Oregon plantation

Creator:: Goracke, Heidi S. Roe
Abstract:: Concern over the increasing proportion of juvenile wood grown in second growth plantations has led to a large amount of research on the effects of common silvicultural practices on wood quality. Lacking is research on the effect of timing and duration of vegetation control on wood quality near the pith...

Soil compaction on a mechanized timber harvest operation in eastern Oregon

Creator:: Zaborske, Richard R.
Abstract:: The use of mechanized harvest equipment has been increasing as an economical method to harvest small diameter timber. While the use of this equipment is increasing, little is known about associated soil compaction. In particular, little information exists on soil compaction caused by feller--bunchers. This study measured soil compaction caused...

Development of a land evaluation and site assessment (LESA) model for forestry in Lane County, Oregon

Creator:: Pepi, Joseph A.
Abstract:: A Land Evaluation and Site Assessment (LESA) Model was developed for the forested soils of Lane County, in western Oregon, based on soil potential ratings and indexes of parcel size and adjacent and surrounding land use conflict. Lane County's economy is heavily dependent on resource production uses of land for...

Dominant-height-growth and site-index equations for Douglas-fir and ponderosa pine in southwest Oregon

Creator:: Hann, David W., Scrivani, John A., Oregon State University. Forest Research Laboratory, and Southwest Oregon Forestry Intensified Research Program
Resource Type:: Technical Report

A water balance model for reforestation sites : description and sensitivity

Creator:: Costello, Craig
Abstract:: A model was developed for analysis of the soil water balance of individual reforestation sites in western Oregon. The numerical procedure for this model was programmed in compiled BASIC language and calculations for an entire season are made in about 180 seconds on an IBM AT microcomputer. The processes that...

Vegetation-environmental relationships on two clearcuts on the western slopes of the Oregon Cascades

Creator:: Egeland, Dawn M.
Abstract:: Douglas-fir and western hemlock growth and stocking were examined on two neighboring clear-cut watersheds in the Western Cascades of Oregon and related to the intensity of burning and logging disturbance, habitat type, soil type, aspect and the influence of percent cover of both invading Ceanothus species and residual Acer circinatum....
