Gecy, J. Leslie; Wilson, Mark V. 1990. Initial establishment of riparian vegetation after disturbance by debris flows in Oregon. American Midland Naturalist. 123: 282-291.
Three debris flows in the western Oregon Cascades were sampled near theend of the first growing season following disturbance. Vegetative regrowth accounted for77% of the initial re-establishment of cover, but 67% of the individuals were seedlingsSurface deposit characteristics and intensity of scour were the most important influences ondebris flow revegetation. Total cover (15%) and vegetative regrowth (14% cover, 28 shoots/m2) were highest on light intensity scour. Seedling establishment was highest on gravel andfine deposits (2-3% cover, 37-46 seedlingsjm2). In contrast to previous studies which high-lighted the role of seedlings, revegetation patterns in these debris flows were determined bythe response of both vegetative sprouts and seedlings.
