In the Pacific Northwest, one of the principal forest growing areas of the world, the evaluation of the soil as a factor in the production of forest resources has an even shorter history, but a great deal of progress has been made. This volume represents an attempt to synthesize the results of these studies and thereby add direction to future work as well as provide current guidelines for management. Chapters include: Geology of the Douglas-Fir Region; The Klamath Mountains and Coast Ranges of Northern California; The Oregon and Washington Coast Ranges; The Willamette Valley; The Cascade Range in Oregon and Southern Oregon; The Olympic Mountains Province; Northern Cascade Mountains; Surficial Geology of the Puget Sound Lowlands; The San Juan Islands; Bedrock Geology of Vancouver; Suricial Geology of Vancouver Island; Geologic Look at Soils of the Douglas-Fir Region; Geology Glossary; Climate; Vegetation; Physical Properties and Physical Behavior of Forest Soils; Minerals, Chemical Properties and Fertility of Forest Soils; Organic Matter of Forest Soils; Forest Soils Biology; Soil Formation, Classification and Morphology; Forest Soil Survey; The Cycling of Elements Within Forests; Forest Soil Productivity Relationships; Soil, Vegetation and Watershed Management; Forest Chemicals in Watershed Management; Some Engineering Aspects of Forest Soils; Soil Management in Douglas-fir Nurseries; Forest Fertilization Practices.
