Managing Forest Stands for Biodiversity in the Northeast United States: An Ecological Economics Analysis
Managing forest stands on small family owners for biodiversity can be accomplished using ecologically sound and economically viable silviculture, but trade-offs exist between eco logical and economic criteria. Protecting and enhancing biological diversity is an important management objective among owners of private family foresflands in the northern United States. In this northern region which accounts for 30％ of US timberland, family owners represent more than 90％ of all private ownerships and more than 70％ of private forest area. The average holding is approximately 8 hm2. This research investigates whether stand management tech niques designed to achieve these biodiversity objectives are economically viable. Using case study data from a mixed temperature deciduous forest, silvicultural prescriptions are simulated to maintain or enhance late successional forest conditions. Stand parameters include species composition, diameter distribution, and structural features associated with a late seral stage. Economic parameters include harvest value and present value of harvest and final inventory. For the case studies examined, a selection harvest favoring shade tolerant species represents a via ble compromise between ecological and economic considerations.
