Book excerpt: A description of the discovery and exploration of southeast Alaska sets the scene for a discussion of the physical and biological features of this region. Subjects discussed include geography, climate, vegetation types, geology, minerals, forest products, soils, fish, wildlife, water, recreation, and aesthetic values. This is the first of a series of publications summarizing present knowledge of southeast Alaska's forest resources. Publications will follow which discuss in detail the subjects mentioned above and how this information can be helpful in managing the resources.

Book excerpt: Large-scale use of the timber resource of southeast Alaska began in 1953 after long efforts to establish a timber industry. 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 Published and unpublished information are brought together. Current management practices are discussed as a basis for a better understanding of how this information can be helpful in managing the timber resource and to point out where research is needed.

Available in PDF, EPUB and Kindle. Book excerpt: The effects of logging and associated activities on fish habitat in southeastern Alaska are discussed, and fish habitat research applicable to southeast Alaska is summarized. Requirements of salmonids for suitable spawning and rearing areas are presented. Factors associated with timber harvest which may influence these habitats are discussed in detail; e.g., sediment, stream temperature, streamflow, logging debris, and chemicals. Recommendations for further research are made.

Book excerpt: The effects of logging and associated activities on the habitat of the major forest wildlife species in southeast Alaska are discussed and research results applicable to this region are summarized. Big game, furbearers, and non-game species are considered with respect to their habitat requirements and behavior. Recommendations are made for habitat management with primary concern for wildlife populations. Future needs for wildlife habitat research in southeast Alaska are presented.

Available in PDF, EPUB and Kindle. Book excerpt: Research in southeast Alaska has identified soil mass movement as the dominant erosion process, with debris avalanches and debris flows the most frequent events on characteristically steep, forested slopes. Periodically high soil water levels and steep slopes are controlling factors. Bedrock structure and the rooting characteristics of trees and other vegetation exert a strong influence on relative stability of individual sites. Timber harvesting operations have a major impact on initiation and acceleration of these movements. The cutting of timber itself has been directly linked with accelerated mass movements, and the accumulation of debris in gullies and canyons has been identified as a major contributor to the formation of large-scale debris flows or debris torrents. The limited road construction on steeper slopes thus far has had a relatively small impact. Effective management practices on such terrain consist of identification and avoidance of the most unstable areas and careful control of forest harvesting operations in questionable zones.

Available in PDF, EPUB and Kindle. Book excerpt: Southeast Alaska has 11.2 million acres of forest land, of which 4.9 million acres are considered commercial. This commercial acreage supports 166 billion board feet of sawtimber. These primarily old-growth stands of Sitka spruce and western hemlock are supporting a growing wood products industry that ranks first in the southeast economy and third in the State. This report summarizes current knowledge of the timber resource (areas, volumes, growth, mortality, quality, productivity, and trends) from the initial inventory, a partial remeasurement, and a second inventory now in progress. Historical data of wood products use, output, value, and markets are given and discussed. The report gives sources for much published and unpublished information for those who need to pursue these subjects more completely.
