WOPR Klamath Mountain Province Landslide Density Raster

Raster representation of landslide probability for the Klamath Mountains physiographic province within the Western Oregon Plan Revision (WOPR) boundary.

BLM: (Bureau of Land Management) WOPR: (Western Oregon Plan Revision) PRMP: (Proposed Resource Management Plan) DEM: Digital Elevation Model Physiographic Province: A region in which the landforms are similar in geologic structure and differ significantly from the landform patterns in adjacent regions.* Landslide Density: The relative probability of a landslide occurrence. *The boundaries used for the landslide density models are based on but do not match the Physiographic Province boundaries in WOPR. The landslide density model is based on 5th field watershed boundaries that do not exactly match the Physiographic Province boundaries. The decision was made to merge the West and East Willamette provinces with the Coast and Cascade regions respectively. The South Cascade region was considered to be unique, in terms of landslide density, from the northern Cascades to merit its own region.
