Two plots (each 8 x 16 m) were established at each of the Icacos and Bisley study sites in 1989 allowing us to make comparisons of decomposition among riparian  and upland plots within watersheds and between watersheds. Similar plots were established in 1990 (riparian and upland, Bisley and Icacos). Since the Icacos upland plot (North side of stream) was only minimally disturbed (defoliated), a fifth plot, hereafter referred to as 1990 Icacos Upland Blowdown plot (data variable designated as South side), was established in an adjacent area that  was severely disturbed.
