Some lessons in artificial regeneration from southwestern Oregon.

Abstract

Natural reproduction has often proved undependable for restocking cutovers and burns in the mixed-conifer forest types of southwestern Oregon. These types, covering 6,000 square miles of productive forest land in the five southwestern Oregon counties, are composed of many species--principally Douglas fir, Pseudotsuga menziesii (Mirb.) Franco; ponderosa pine, Pinus ponderosa Laws.; sugar pine, Pinus lambertiana Dougl.; incense cedar, Libocedrus decurrens Torr.; grand fir, Abies grandis (Dougl.) Lindl.; and white fir, Abies concolor (Gord. & Glend.) Lindl. Each of these species is commercially important; but three, Douglas fir, ponderosa pine, and sugar pine, may be preferable for specific environments.
