1 Multi-attribute planning in GIS for ecosystem protection Fraser Shilling Department of Environmental Science & Policy University of California, Davis

2 Multiple attribute planning Previous studies in California Sierra Nevada (Shilling et al., 2002; Shilling and Girvetz, 2007) Used GIS-based spatial modeling, founded on expert input about focal wildlife species and landscape/aquatic fragmentation. Tools: Ecosystem Management Decision Support (EMDS) & simulated annealing program (SITES) – now MARXAN

4 How much does it cost? Cost included post- hoc, but could have been used as input variable

5 Best approach (lessons learned and literature) ► Goals/objectives ► Multiple scalable attributes and values ► Geographic expression ► Cost and planning implications ► Attributes on same value scale ► Indicators of ecosystem/social value ► Indicators correspond to goals/objectives
