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

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
