Multi-attribute planning in GIS for ecosystem protection Fraser Shilling Department of Environmental Science & Policy University of California, Davis fmshilling@ucdavis.edu
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

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