Book excerpt: "This publication presents a history of the Forest Survey (now known as Forest Inventory and Analysis) program in the United States as it evolved within the U.S. Department of Agriculture (USDA) Forest Service over a period of more than 100 years. It draws on the writings of several authors who have published on various aspects of the Forest Survey program. A review is presented of nine ground plot designs used in the Forest Survey and Forest Inventory and Analysis (FIA) programs since 1931. This publication also highlights the major events contributing to the current FIA program, beginning as far back as 1830. It is impressive to look at the many contributions of various people working with the Nation's Forest Survey program, as well as the various methodologies that have contributed to understanding and updating the national forest survey statistics. It is especially timely that this historical report should occur at the time the Forest Service just celebrated the anniversary of its 100 years of service to the American people."--Publisher's website.

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.
