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 Layers14 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

Data Layers• Environmental

Diseases

• Economic– Topography– Wildfire– Insect and

Disease– Development– Soils– Distance to

Milling Facilities– Proximity to

Industrial Lands– Notification of

Operations

• Social– Public Water

Supply– Development– Percent of

economy from forest sector

– Hunting Opportunities
