Silvicultural technology and applications for forest plantation establishment west of the Cascade crest.

Abstract

Research and operational trials have identified methods of forest plantation establishment that promote high rates of survival and early growth of tree seedlings in the Pacific Northwest. Primary reasons for this success are the intensive control of competing vegetation provided by herbicide treatments and the planting of high quality seedlings. This paper discusses the current state of the art in forest plantation establishment in Oregon and Washington west of the crest of the Cascade Range. It considers technologies developed in the last two decades that currently have widespread application on lands managed primarily for wood products. The focus of this review is on even-aged silviculture of conifer seedlings, especially coastal Douglas-fir (Pseudotsuga menziesii Mirb.) Franco var. menziesii), but other species, silvicultural systems, and regions are considered where appropriate.
