Developments to the Sylvan Stand Structure model to describe wood-quality changes in southern bottom-land hardwood forests because of forest management.

GROWTH MODELS CAN PRODUCE A WEALTH of detailed information that is often very difficult to perceive because it is frequently presented either as summary tables, stand view or landscape view visualizations. We have developed new tools for use with the Sylvan model (Larsen 1994) that allow the analysis of wood-quality changes as a consequence of forest management. Sylview is a new computer program that allows users to visualize wood-quality characteristics of stands and individual trees within a stand. These include the effects of spacing and thinning on taper, branch size, and clear wood production.
