Book Description
Invasions of non-native plants into forests of the Southern United States continue to go unchecked and only partially un-monitored. These infestations increasingly erode forest productivity, hindering forest use and management activities, and degrading diversity and wildlife habitat. Often called non-native, exotic, non-indigenous, alien, or noxious weeds, they occur as trees, shrubs, vines, grasses, ferns, and forbs. This guide provides information on accurate identification of the 56 non-native plants and groups that are currently invading the forests of the 13 Southern States. In additin, it lists other non-native plants of growing concern. Illustrations. This is a print on demand edition of an important, hard-to-find publication.

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.
