Height-diameter and volume equations, growth intercept and needle length site quality indicators, and yield equations for young ponderosa pine plantations in Neuquén, Patagonia, Argentina

Creator:: Gonda, Hector Eduardo
Abstract:: Ponderosa pine (Pinus ponderosa Dougl. ex Laws.) is the most widely planted species in the Patagonian Andes region of Argentina for economic development. However, information on site quality and yield is so limited that potential forest investors and managers do not have a reliable basis on which to make sound...

Comparative effects of chemical, fire, and machine site preparation in an Oregon coastal brushfield

Creator:: Kelpsas, Bruce Robert
Abstract:: Four brushfield reclamation methods were compared on a 28 hectare area supporting a dense overstory of red alder and a thick understory of deciduous brush species. Tractor scarification, aerial application of 2, 4, 5-T and picloram followed by broadcast burning or tractor crushing, and aerial application of glyphosate were performed...

The valuation and use of site information for Douglas-fir reforestation in Western Oregon : a decision analysis

Creator:: Schöne, Dieter Hans-Friedrich
Abstract:: Existing forest site maps have been described as "invaluable tools" in forest management. Their, economic value potentially materializes as the summed advantage from better decisions in all phases of forestry. Via Bayesian decision analysis, this study establishes optimal use and economic value of site information for one facet of management...

Lumber grades vs. site quality of second-growth Douglas-fir

Creator:: Forest Products Laboratory (U.S.) and Paul, Benson H.
Resource Type:: Technical Report
Full Text:: " or "site quality" is meant the combined effect of the environmental characteristics of forest areas

A comparison of prediction models for cover type transitions and their effects on harvest schedules in coastal Oregon

Creator:: Eng, Helge
Abstract:: There is considerable uncertainty associated with stand establishment in coastal Oregon. Several species can gain control of the site depending on stand conditions as well as management practices. In this study, three cover type transition models were developed using data from the Siuslaw National Forest to predict stand establishment patterns...

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....
