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.

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 Published and unpublished information are brought together.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.

This publication presents highlights of a recent southeast Alaska inventory and analysis conducted by the Pacific Northwest Research Station Forest Inventory and Analysis Program (USDA Forest Service). Southeast Alaska has about 22.9 million acres, of which two-thirds are vegetated. Almost 11 million acres are forest land and about 4 million acres have nonforest vegetation (herbs and shrubs). Species diversity is greatest in western hemlockAlaska cedar closed-canopy forests, in mixed-conifer open and woodland forests, and in open tall alder-willow shrub type. Of the forest land, 4.1 million acres are classified as timberland (unreserved productive forest land). About 4.4 million acres of forest land are reserved from harvest; the majority of this reserved land (85 percent) is on the Tongass National Forest (USDA Forest Service). The volume of timber on timberland was estimated at 21,040 million cubic feet; the majority of volume88 percentis on the Tongass National Forest. Seventy-four percent of timberland acres and 84 percent of the growing-stock volume is in sawtimber stands older than 150 years, with western hemlock or western hemlockSitka spruce mix predominating. Most timberland in southeast Alaska is of relatively low productivity, producing less than 85 cubic feet per acre per year. For most timberland acres, average annual growth exceeds average annual mortality and harvest.

Rural communities in the western U.S. and Alaska are highly dependent upon surrounding publicly-owned forests for various economic and non-economic values. Historically, limited data has hampered the understanding of such community-resource linkages. As a result, community interests may not be adequately considered in forest management plan development and policy formulation. Addressing this imbalance is an important issue for the U.S. Forest Service (USFS), particularly as it shifts from timber-dominated goals to a more holistic ecosystem-based form of management. This study seeks to understand community-resource use linkages, dependency, and vulnerability surrounding the Chugach and Tongass NFs using place-level socioeconomic data from the 2000 U.S. Census in combination with permit data from the USFS's Timber Information Management Data System (TIM) and Special Use Data System (SUDS). Information on permittees' activities on forestland and socioeconomic profiles of permittee's community-of-origin are found to be valuable, not only for forest management and planning purposes, but also for community-level social assessment. An examination of 2007 permit data found that a majority of permit holders were local residents. These communities are found to be dependent on the two forests for various types of activities and are thus more likely to be vulnerable to changes in forest management and policies. The analysis also identified some limitations that may affect the quality of permit data and its potential use in community impact assessments. Despite these limitations of permit data, the methodologies utilized here demonstrate how TIM and SUDS data, in combination with U.S. Census data, could be used to describe Alaska residents' socioeconomic profiles for communities located in close proximity to the Tongass and Chugach NFs. Such information can assist USFS managers in deriving community-level estimates of forest resource use, degree of dependency, and vulnerability to the likely impacts of alternatives management approaches. Finally, recommendations are given to improve data recording, maintenance, and use in order to better understand communities that are dependent on forest resources in both the Chugach and Tongass NFs, and to specifically identify those communities potentially vulnerable to changes in forest management policies.
