Capabilities for evaluating biodiversity concerns
Examples of use
1.Numerous (in hundreds) East Coast federal, state and private foresters use NED to prepare forest stewardship plans.
2.Mike Rauscher of the Forest Service (828-667-5261) has adapted and used it on private lands in South Carolina.
3.It is being used on Ft. Campbell's 70,000 acres (contact: Steve Forry 270-956-3376).
4.Maryland DNR is working to adapt and use NED to analyze different properties in terms of water quality, wildlife, recreation and biodiversity (contact: Rob Northrop 410-287-2918).

7 Elements of sustainability (Davis, et. al. 2001)
Ecosystem Management Decision Support is primarily designed to help users conduct ecological assessments. It provides a framework for users to integrate spatial information (using ArcGIS) with models of how to evaluate this information (using the Netweaver knowledge-base builder).
Applied to the Montreal C& I.
The 1970s—the golden age of DSS for commercial timber supplies. For this work, we had:
Is now the golden age for forest biodiversity DSS?
3.What would you need to know to help you select appropriate tools?
a. What attributes of systems are likely to make them most useful?
b. What aspects of DSS cause you to have reservations about their use?
4.How would biodiversity implications from these systems need to be expressed to make them comparable to other major factors that typically influence your decisions?
