Book Description
Excerpt from A Survey of Factors Affecting Regeneration of Rocky Mountain Douglas-Fir To help delineate regeneration problems before developing a research program, I conducted a field reconnaissance in 1968 and 1969, of Rocky Franco) cutting areas in Forest Service Regions 1 and 4. From file records and field measurements, I obtained information about topography, soils, seed bed, shade, competing vegetation, opening size, habitat type, and history of treatment. Success of Douglas-fir regeneration is presented as percent milacre stocking. Results indicate that the effects of various regeneration methods and the success expected depend largely upon habitat type. Thus, attempts to generalize about seedbed, shade, and other species require ments can be misleading. Results were used to develop a research pro gram for regeneration of Douglas-fir. Problem solutions seemed to center around the need for more careful administration of planting operations and plantation protection and for development of silviculture prescriptions to match species requirements and site potential.

Excerpt from Douglas Fir: A Study of the Pacific Coast and Rocky Mountain Forms Montana, Colorado, Idaho, and Utah third. In 1907, board feet of Douglas fir were cut in the Rocky Mountains, which constituted per cent of the total cut for this region; The per centage was lowest per cent) in Arizona, and, strangely enough, next to the highest per cent) in the adjoining Territory of New Mexico.

Book Description
Silviculture: Concepts and Applications reflects a belief that all the tools of silviculture have a useful role in modern forestry. Through careful analysis and creative planning, foresters can address a wide array of commodity and nonmarket interests and opportunities while maintaining dynamic and resilient forests. A landowner’s needs, circumstances, and site conditions guide a silviculturist’s judgment and decision making in finding the best ways to integrate the biologic-ecologic, economic-financial, and managerial-administrative requirements at hand. The Third Edition of this influential text provides a foundational basis for rigorous discussion of techniques. The inclusion of numerous real-world examples and balanced coverage of past and current practices broadens the concept of silviculture and the ways that managers can use it to address both traditional and emerging interests in forests. A thorough discussion of new and proven interpretations increasingly directs the attention of foresters toward the role silviculture plays in creating, maintaining, rehabilitating, and restoring forests that can sustain an expanding variety of ecosystem services.
