This book was released on 2023-07-18 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive guide to managing these two important tree species for maximum timber yield. Ruth and Harris discuss various silvicultural techniques and their impacts on growth, yield, and quality. They also address issues such as stand density, site preparation, and regeneration. This is a valuable resource for forest managers, loggers, and anyone interested in sustainable forestry practices.

Download or read book The Effects of Partial Cutting on Stand Structure and Growth and Forest Plant Communities of Western Hemlock Sitka Spruce Stands in Southeast Alaska written by Robert L. Deal and published by . This book was released on 1999 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study evaluated the effects of partial cutting on stand structure and growth, patterns of conifer regeneration, stand mortality and disease, and understory plant diversity and abundance. Seventy-three 1/5 ha plots were established in 18 partially cut stands throughout southeast Alaska. These stands were partially cut 12 to 96 years ago removing 16 to 96 percent of the original stand basal area. Partial cutting resulted in stands that had complex structures and these structures appear similar to uncut old-growth stands. Sitka spruce was maintained over a wide range of cutting intensities, and conversion to hemlock-dominated stands generally did not occur. New spruce regeneration was established in 23 of 55 partially cut plots compared with new spruce found in only 2 of the 18 uncut plots. The current stand basal area, tree species composition, and stand growth were strongly related to trees left after harvest. Trees that were 10 to 70 cm d.b.h. at time of cutting had the greatest tree diameter growth. Little of the stand growth since harvest came from new regeneration or trees greater than 70 cm d.b.h. The diameter growth of residual hemlock and spruce trees were similar The species richness of vascular plants and bryophytes was similar among uncut and partially cut plots and did not significantly change with different cutting intensities. Overall, plant community structures were similar between the uncut and partially cut plots. However, moderate and heavy cutting intensities resulted in stands that had significantly different plant community composition. The abundance of most deer forage plants did not significantly change after partial cutting. It appears that silvicultural systems that use single tree selection or small openings can be successful for timber management purposes in southeast Alaska. Concerns about changing tree species composition, lack of spruce regeneration, greatly reduced stand growth and vigor, increased dwarf mistletoe infection in hemlock trees, and higher incidence of tree wounding, decay, and mortality with partial cuts were largely unsubstantiated. Stand structural diversity, species richness and understory plant abundance were all greater in partially cut stands than in young-growth stands developing after clearcutting.

Book excerpt: Excerpt from Growth and Yield of Sitka Spruce and Western Hemlock at Cascade Head Experimental Forest, Oregon This report describes the study, summarizes data obtained from the permanent sample plots, and discusses results. Our primary purpose in pre senting these data is to further define the extraordinary productivity of the Sitka-spruce - western hemlock coastal forest. This information on growth and yield focuses on cause-and-effect relationships rather than on indepth statistical analyses of the data.
