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....

The effects of mechanical and chemical site preparation on ponderosa pine (Pinus ponderosa Dougl. ex Laws.) and lodgepole pine (Pinus contorta Dougl. ex Loud.) performance, associated vegetation, and soil properties in southcentral Oregon eight years after planting

Creator:: Ross, Darrell W.
Abstract:: The effects of six alternative site preparation treatments were compared at three different sites in southcentral Oregon. Treatments included a logged-only control, ripping, brushblading, disking, chemical, and chemical followed by disking. Subplots containing ponderosa pine bareroot (2+0) and containerized (1+0) and lodgepole pine containerized (1+0) seedlings were also included in...

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...

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...

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...
