Multi-attribute planning in GIS for ecosystem protection

Explore the use of GIS-based spatial modeling for ecosystem protection in California's Sierra Nevada region, incorporating expert input on wildlife species and landscape fragmentation. Learn about tools like EMDS and MARXAN for effective planning.

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

  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
