A model of forest nitrogen cycling to assess the effects of management intensity on long-term productivity in Douglas-fir forests of the Pacific Northwest

O Criador:

Krzak, Joan

Abstract:

The objective of this study was to assess the effects of forest management intensity on long-term productivity of Pacific Northwest Douglas-fir forests. The components of management intensity included rotation length, timber utilization standard (whole tree or bole only), method of slash treatment (remove/burn or leave) and fertilization practice (urea nitrogen...

Wood properties and use of sensor technology to improve optimal bucking and value recovery of Douglas-fir

O Criador:

Acuna, Mauricio A.

Abstract:

There are a number of wood properties which affect the quality of forest products such as lumber and pulp. Of these, wood density is considered by some to be the single most important physical characteristic because it is an excellent predictor of strength, stiffness, hardness, and paper-making capacities. Accurately assessing...
