Two hundred and fifty-four nonindustrial private forest landowners in western Oregon were surveyed to develop baseline information about harvesting practices and to
examine the influence of marketing procedures on delivered log prices. Most respondents harvested to meet income or
silvicultural objectives. Harvests on ownerships less than 50 acres in size...
Metric spaces (X, d) are ubiquitous objects in mathematics and computer science that are able to capture pairwise distance relationships d(x, y) between points x, y ∈ X. Because of this, it is natural to ask what useful generalizations there are of metric spaces for capturing “k-wise distance relationships” d(x1,...
Himalayan blackberry (Rubus armeniacus, formerly Rubus discolor and Rubus procerus) is a European shrub that was introduced in the United States as a crop in the late 19th century. It escaped cultivation and has since invaded a variety of sites, including low-elevation streamside areas throughout the Pacific Northwest. Listed as...
Pruning is removing the lower branches of trees (Figure 1). Increasing the distance between the ground and the lowest tree
branches reduces the likelihood that a fire on
the ground will use the branches as a ladder to
move into tree crowns. A crown fire is more
difficult to control...
Thinning is one of the most powerful forest management tools available to landowners for achieving a wide range of goals and objectives.
Thinning influences:
• Trees’ growth rates and potential economic value
• Which species of trees and other plants will be in the stand
• Trees’ resistance to insects...
This publication provides an overview of how various silvicultural treatments affect fuel and fire behavior, and how to create fire-resistant forests. In properly treated, fire-resistant forests, fire intensity is reduced and overstory trees are more likely survive than in untreated forests. Fire-resistant forests are not “fireproof” – under the right...
Many manual and mechanical methods are used to reduce
hazardous fuels on woodland properties. This publication describes
three of the most common methods:
• Slashbusting and grinding
• Mowing and mastication
• Crushing
Thinning to reduce hazardous fuels often generates large amounts of woody residues, such as small-diameter logs, tree
tops, and branches. This publication discusses
several options for economically and effectively
using and disposing of woody material.
