What We Learned Strengths –Solid Concept –Visual products have value –Analysis straight forward and quick Weaknesses –Weighting multiple layers –Mixing agriculture and forest lands –Initial layers appear to focus of environmental factors –Data limitations

Weighting Data Layers 14 Layers Dilutes value of weight Example: With 14 layers, each worth 7.1%. Weighting one twice as important, 14.2%, has remaining layers at 6.6% each. Difference being 7.6% With 4 layers, each worth 25%. Weighting one twice as important, 50%, has remaining layers at 16.7% each. Difference being 33.3%

Data Layers Environmental –Forest Patches –T&E Species –Wetlands –Riparian Areas –Proximity to Public Lands –Priority Watersheds –Public Water Supply –Wildfire –Insect and Diseases Economic –Topography –Wildfire –Insect and Disease –Development Social –Public Water Supply –Development
