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. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books. Find more at www.forgottenbooks.com This book is a reproduction of an important historical work. Forgotten Books uses state-of-the-art technology to digitally reconstruct the work, preserving the original format whilst repairing imperfections present in the aged copy.
