Forest Operations: Examined actual costs of harvesting with cut to length systems on the Rocky II timber sale and found that harvest costs increase rapidly as average stand diameter drops below 10 inches.
Collaborators: The Colville, Idaho Panhandle, and Ochoco National Forests; Boise Cascade Corp.; Riley Creek Lumber; Vaagen Brothers Lumber; Oregon State University; the University of Idaho; the University of Washington; Washington State University; the USDA Forest Service, Forest Products Laboratory and Pacific Northwest Research Station.

Study Description: The study
team evaluated treatments intended to meet a range of ecological
objectives: (1) increase structural diversity, (2) decrease
forest health risk, (3) improve wildlife habitat, (snags
for cavity nesting birds and winter range for White-tail deer);
and (4) improve stand aesthetics (promote development of
large diameter western larch).
Wood Product Potential:
Conversion studies were conducted for lumber, veneer, oriented
strand board (OSB), particleboard, laminated veneer lumber (LVL),
and pulp. The quality of products manufactured from small diameter
Douglas-fir, larch, lodgepole pine, and white fir trees from densely
stocked stands was typically as good as, or better than, the quality
of the traditional large diameter resource.
