Abstract:

Current Information see: NED Project , Northeastern Research Station NE-4454: "Integrating the Ecological and Social Dimensions of Forest Ecosystem Management"

The Northeast Decision Model is a decision support system that contains a combination of knowledge-based modules, expert systems and simulation components. The model is designed to examine potentially conflicting strategies of forest silviculture strategies.

The model requires the user to provide information on the goals of silviculture treatments, an inventory of trees under the potential prescription and terrain data. The model evaluates the management strategies and provides the user with a prediction of the vegetation composition and structures likely under each strategy. Other output includes wildlife habitat conditions. The model is generally run over a 50 year period and examines silviculture options at the watershed scale.
