Project Goal: What areas in Gifford Pinchot National Forest are suitable for timber harvest?

Project Area

Data Used Boundary of the Gifford Pinchot National Forest Critical Owl Habitats North Spotted Owl habitat Grey Owl habitat Riparian Reserves Slope Topography Rivers Water body http://www.fs.fed.us/gpnf/forest-research/gis/

Analysis Criteria for Harvestable Lands: Within the Forest Boundary Outside Owl Habitat Outside Riparian Reserves Slope less than 60%

Analysis Tools used: Clip Union Select Total Area Of Harvestable Land ≈ 2 million acres

Estimated Worth of Harvestable Land in GPNF ≈ $19 billion Analysis Revenue calculations: Washington State Department of Revenue Stumpage Values Per Thousand Board Feet Estimated Worth of Harvestable Land in GPNF ≈ $19 billion

Conclusions: Total Area Of Harvestable Land ≈ 2 million acres Estimated Worth of Harvestable Land in GPNF ≈ $19 billion
