A comprehensive guide to effective hardwood forest management Extending 235,000 square miles from New York to Georgia and fromVirginia to Missouri, the Central Hardwoods Region harbors the mostextensive concentration of deciduous hardwoods in the world. Asharvests in the Pacific Northwest decline and timber prices rise,the maturing stands of mixed species in this central U.S. regionare a rich and valuable resource that is increasingly vulnerable toexploitation. This timely book examines all of the key ecological,social, and economic management considerations essential to utilizeand sustain these vital woodlands effectively. First, it develops the background necessary to understand whatmakes the hardwood eco-system function, with a thorough examinationof the physiography, geology, soils, and climate of the region anda historical overview of its evolution and development frompre-European settlement to the present. Then, species by species,the book details the silvical characteristics of 34 important treespecies. Next, it offers expert recommendations for effectiveforest treatment and management, from specific concerns such astimber production, pollution, and financial planning to broaderissues, including the role of the natural resource manager and thebiological potential of the entire region. Generously supplemented with graphs and photos, Ecology andManagement of Central Hardwood Forests is important reading forforesters, natural resource managers, regional planners,environmental scientists, governmental officials--everyone with astake in the future of this critical living resource.

S2Decisions to manage immature eastern hardwood stands on steep terrain must be based on an understanding of the impact of timber production costs on optimal rotation length and present net worth. Planners and managers can make improved decisions by knowing how the interaction of timber production and transportation costs affect individual stand management. Simulations with a complete systems model indicate that managers and planners must consider cable logging technology, transportation network standards, and transport vehicles. S3.

Long-term recreation planning requires an understanding of recreation participation patterns. This study examined Vermonters' participation in 27 leisure activities from three domains (outdoor, resource based, and indoor) to see how such participation differed in each domain. Indoor activities were the most popular, followed by resource-based activities and general outdoor activities. Overall participation declined with age, though this effect was mitigated somewhat for older parents. Other socioeconomic and demographic variables had limited effects on participation.

S2Small-sawtimber white oak crop trees in Kentucky were released by a crown-touching technique. In two cutting treatments, 20 and 34 crop trees were released per acre at a total cost of $35 and $42, respectively. Both treatments yielded commercial volumes of cut material. Total mean merchantable volume (>5.0 inches d.b.h.) in cut trees was 693 cubic feet/acre, with approximately 2,400 board feet/acre in sawtimber (2 11.0 inches d.b.h.). On the basis of early crop-tree stem response, the released trees are growing 0.16 inch/year compared with 0.13 inch/year for the unreleased trees. S3.
