The ForestERA toolkit uses a spatial decision support system (SDSS) made up of software tools and user guides in a collaborative environment to aid stakeholders in developing forest management scenarios and testing their cumulative effects on wildlife habitat and fire hazard and behavior. The tools carry the user through the SDSS “workflow” by integrating various fire, wildlife, watershed and other decision-making criteria with user preferences for application (see Figure 1). For example, a user may be interested in designing a set of restoration treatments (e.g., various thinning and/or prescribed burning treatments) to meet one or more forest management objectives while exploring the cumulative effects of this management “scenario” on Mexican spotted owl habitat and fire hazard reduction.
