km reach north of Harrisburg, Oregon, were evaluated. The cover classification scheme
included 18 classes composed of 3 canopy densities and 8 structural...
The Slices Framework is intended for use in making decisions about conservation and restoration in the Willamette River floodplain. It makes use of distinct spatial units for tracking change in the floodplain. The first of these units are 1 kilometer long slices drawn at right angles to the floodplain, first...
