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.

This book was released on 2015-06-26 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hemlock dwarf mistletoe (Arceuthobium tsugense [Rosendahl] G.N. Jones) is a small, inconspicuous parasite that has significant effects on tree growth and stand structure in coastal forest ecosystems of western North America. Most previous research focused on the effects of hemlock dwarf mistletoe on timber production. Previous clearcut harvesting of large areas that removed virtually all infected trees and forestry practices that established even-aged stands of trees effectively prevented or minimized future hemlock dwarf mistletoe impacts. Under this regime, further research on hemlock dwarf mistletoe was considered unnecessary. However, current forestry practices that restrict clearcut harvesting to small openings and retain live trees to preserve attributes of old-growth forests create conditions that appear highly favorable for enhanced seed production by hemlock dwarf mistletoe, early spread of the mistletoe to infect young trees, and, consequently, increased growth impacts to residual trees over time. More information is needed on the biology and impacts of hemlock dwarf mistletoe in coastal western hemlock retention-harvested forests in the United States of America and Canada. Further work is recommended to develop sampling and monitoring procedures to determine hemlock dwarf mistletoe spread and impacts. We also need to investigate several unusual aspects of hemlock dwarf mistletoe biology and development such as long-distance seed dispersal and persistence in old-growth forests. Detailed tree, stand, and forest-level models are needed to monitor and project hemlock dwarf mistletoe effects over a wide range of ecological conditions and management regimes in coastal forests.

Book excerpt: Wildfires play a multiple role in the distribution of dwarf mistletoes - they may either inhibit or encourage these parasites depending primarily on the size and intensity of the burn. Many reports suggest that fire exclusion policies of the past half century have resulted in increased dwarf mistletoe levels as, well as increased fire behavior potential. Prescribed burning as a supplemental method of dwarf mistletoe control has been little used, but seems to be applicable in some forest types and stand conditions both to eliminate infected residuals in cutover areas and to eliminate heavily infested unmerchantable stands. Suggested areas of research relating to fire ecology and prescribed burning are given.
