Book excerpt: Excerpt from Forest Insect and Disease Conditions in Alaska Ground and aerial surveys detected significant blotch miner damage on hectares of quaking aspen near Fairbanks. Before last summer, damage caused by this miner was practically nonexistent. It was not until 1977 that the causal agent was identified as L. Ontario. Likewise, a related but unidentified species of Lithocol/etis caused considerable mining on alder in and around Fairbanks. Efforts will be undertaken next year to monitor the effects of these hardwood blotch miners. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from A Forest Disease Survey of Alaska In the summers of 1952 through 1954 an extensive forest disease survey was made through out Alaska, and 250 fungus collections were made. The purpose of the survey was primarily to observe the general health of the native forest trees and to determine whether any epidemic dis ease conditions existed there. Much of the survey was by observations from the air, although brief observations were frequently made on the ground. As a part of the survey, the cull in commercially important forest trees was studied in Southeast Alaska3. This report is a brief summary of the general disease conditions found and a listing of the fungi collected during the survey.

Download or read book The Forest Ecosystem of Southeast Alaska written by John S. Hard and published by . This book was released on 1974 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Southeast Alaska's remaining virgin forests have few insect pests. The black-headed budworm and the hemlock sawfly, both western hemlock defoliators, are the most important species. They kill some trees, kill tops in others, and cause growth loss, but stands survive their attacks. Extensive conversion of virgin stands to second growth may result in an increase in pest problems as it has in similar areas such as coastal British Columbia. ‍?‍?Widespread use of insecticides to control major outbreaks is not practical because of risk of contaminating salmon-spawning and trout-rearing streams; but insecticide use may be justified in local, high value areas. Weather, diseases, and parasites control outbreaks naturally. Damage-prone stands should be identified and harvested before insect attack or salvage-logged following outbreaks. Ideally, second-growth stands should be managed for resistance to insect pests.
