The environmental effects of residue removal and whole-tree utilization for several forest types in the United States are being investigated. Sites were selected to include northern hardwood, northern coniferous, southern Appalachian oak-hickory, northwestern coniferous, and southern pine forests. All sites have been established at locations having a long history of biomass and nutrient cycling research, in order to provide a foundation of data to assess the effects of whole-tree harvest on erosion, nutrients, water quality, and productivity. This report (the second in a series) briefly describes the sites, sampling procedures, and reports some preliminary data. Harvesting, including bole-only and residue removal, is complete at most of the sites and preliminary ecosystem nutrient budgets are presented. Aboveground biomass and soil nutrient pools (N, P, K, Ca, Mg) are also given. Carbon analyses have been initiated at one site (Oak Ridge, Tennessee) with others scheduled to begin during calendar year 1981.
