Goals of the USGS Changing Arctic Ecosystem Initiative
Capacity Building for Modeling
The USGS and resource management agencies are increasingly using Bayesian Networks (BNs), Structured Decision Making (SDM), and other similar knowledge-based modeling approaches. BNs provide a versatile framework for integrating empirical data with expert opinion, which often is required when modeling ecosystems where much is unknown. SDM provides an objective, quantitative means to integrate ecological knowledge with multiple management objectives and constraints, to arrive at an optimal management decision. SDM is an integral component of adaptive management. The CAE Initiative is developing additional USGS capacity in these modeling approaches.
