摘要

Information for conservation decisions is often scarce and replete with uncertainty. There may be little agreement about the ecological objective that should be targeted by conservation management and quick turnaround is often needed to make decisions. To support this process, evaluation tools are needed to make informed long-term regional resource decisions and recognize research needs. These tools can help authorities involved in ecological restoration identify decision variables, develop problem solving heuristics, and evaluate the consequences of alternative policy actions. Spatial decision support systems (SDSS) for natural resource management are computer-based tools that tightly integrate decision theory models with ecological models and geographic information systems (GIS) analyses and mapping. The information SDSS provides gives decision-makers increased ability to follow outcomes of interacting variables, improves the reproducibility of decisions and documents why, with conflicting alternatives, a particular choice was made (Rauscher 1999). We envision four components for decision support of landscape habitat evaluation (fig. 1). The first two components, primarily intended for use by the scientist, assist in evaluating what criteria best define performance measures for ecological evaluation and what value those criteria will have with a particular scenario. The first component is an analysis of the proposed scenarios and their respective effects on the physical environment. These analyses are supported by inputs from models that simulate each scenario, such as hydrologic models, urban growth models, and water quality models.
