Development and present status of the industry and present management of the timber resource are summarized, stressing the biological basis for timber management activities in southeast Alaska today. Ecological and silvicultural considerations related to timber harvest, reforestation, and stand development are discussed. Published and unpublished information are brought together.

This book was released on 2008-10-01 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hemlock dwarf mistletoe (HDM) (¿Arceuthobium tsugense¿) is a small, inconspicuous parasite that has significant effects on tree growth and stand structure in coastal forest ecosystems of west. N. Amer. Previous clearcut harvesting of areas that removed all infected trees, and forestry practices that established even-aged stands of trees effectively prevented HDM impacts. However, current forest practices that restrict clearcut harvesting to small openings, and retain live trees to preserve attributes of old-growth forests create conditions that are favorable for enhanced seed production by HDM, early spread of the HDM to infect young trees, and, increased growth impacts to residual trees. More info. is needed on the biology and impacts of HDM. Illustrations.
