Effect of Herbicides on Salmonberry and on Sitka Spruce and Western Hemlock Seedlings

Extract

In coastal Oregon, mild climate, highly productive soil, and annual precipitation of as much as 130 inches combine to produce an exceptionally high rate of forest growth. When these forest stands are harvested, however, brush establishes rapidly in the openings, competes strongly with conifer reproduction, and eventually causes a reduction in timber yields. Such losses are serious in a region which depends largely on the timber resource.
