For tree communities only stems greater than 15 cm in diameter were sampled. We limited the search for dams to areas in third order basins to streams with a <5% gradient and a stream width of <5m. Reaches sampled were surrounded by mature forest stands.

- Methodology_Description:
-
Four basins were chosen from a population of beaver-occupied basins in the lower Alsea drainage area of the Oregon Coast Range for proximity to one another and a high proportion of reaches flanked by mature stands. Within basins, three each of impoundments caused by beaver, impoundments caused by other factors (debris jams) and unimpounded stream reaches were randomly chosen for further study. Dams were further visually classified as new dams (no more than one year old in places that appeared to have no impoundment history), recolonization dams (new dams in areas impounded in the recent past) and old dams (dams that appeared to be many years old; frequently had willows growing from the cuttings anchoring the dams in place). In order to place unimpounded and jam sites in the same geomorphic context as the impoundment sites, the site selection (for all site classes) within a basin was limited to the set of sites typically occupied by beaver as described by the Habitat Suitability Index (HIS) for beaver in the Coast Range (Suzuki and McComb 1998). Suzuki and McComb (1998) concluded that beaver preferentially located their dams in streams with <3% gradient, a stream width of 3-4 m, and valley floors of 25-30m. We limited the search for dams to areas in third order basins to streams with a <5% gradient and a stream width of <5m. Reaches sampled were surrounded by mature forest stands.
At each site, the area surrounding the impoundment/stream reach was visually divided into littoral and emergent zones based on vegetative communities. Transects bisecting the center of the impoundment or stream at 45, 90, and 135 degree angles to the stream were established, and six 1x1m plots were located in each zone on these transects (see figure). Cover of each herbaceous and shrub species in 5% increments was determined for each plot, along with environmental variables (width of stream, width of valley floor, overstory cover, and height of vegetation plot above water level). Overstory cover (at center of site, in 5% increments) was visually estimated for each site; width of valley floor (at dam) and width of stream were measured using meter tape (width of stream for impoundments was measured just downstream of the dam splash pool
