Book Description
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.

Book Description
This report focuses on economic trends since the 1970s in rural southeast Alaska. These trends are compared with those in the Nation and in nonmetropolitan areas of the country to determine the extent to which the economy in rural southeast Alaska is affected by regional activity and by larger market forces. Many of the economic changes occurring in rural southeast Alaska, such as the decline in the manufacturing sector, are reflections of broad-scale changes in the greater U.S. economy. Other changes, such as the increase in nonwage income as a percentage of total income, have been greater in rural southeast Alaska than at the larger scales of comparison. In chapter 1, Robertson describes these changes and their underlying causes and outlines some of their implications for the management of the Tongass National Forest. Providing forest-based recreational opportunities and aesthetic amenities is becoming increasingly important as tourism and residential activity compose a larger portion of the regions economy. In chapter 2, Crone provides a historical context for the economic changes in rural southeast Alaska. She also establishes the global context for these changes, concluding that forces at local, national, and international scales have shaped economic growth patterns in rural southeast Alaska.
