This dataset shows the potential wood contribution to fish bearing streams for the Western Oregon Plan Revision (WOPR). The potential wood contribution is determnined for all streams over entire channel networks, including wood recruitment processes for channel-adjacent tree fall, mass wasting and channel migration. Model inputs are 10 meter Digital Elevation Models (DEM) and forest cover with detailed forest stand tables specifiying stem density,size and mortality rates for each size class in each stand type.
