The environmental effects of residue removal and whole-tree utilization for several forest types in the United States are being studied. Sites were selected to include central hardwoods, northern hardwoods, 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 to provide a foundation of data to assess the effects of whole-tree harvest on erosion, nutrients, water quality, and productivity. This report (the fourth in a series) describes the direct effects of intensive harvesting and some regeneration effects. Harvesting, including bole only and residue removal, is complete at all sites, and ecosystem nutrient budgets for most sites are presented. Short-term direct effects on nutrients cycling processes, impacts of different intensities of harvest on nutrient pools, and uncertainties of long-term effects are discussed. A brief discussion of implications of whole-tree removal is included. 12 references, 9 figures, 43 tables.
