Soil shear resistance and plant community recovery after disturbance in a montane riparian ecosystem
Vegetation recovery after a severe cattle trampling disturbance was studied in a montane riparian community. The disturbance allowed for the successful establishment of cuttings of mountain willow (Salix monticola Bebb.). However, most of the planeleaf willow (S. planifolia) cuttings had very poor establishment. Weedy annual forbs were present after the first and second years following the grazing disturbance. But, after six years of recovery the weedy forbs had declined and the dominant sedge (Carex spp.) community returned. However, some introduced forbs still persisted after six years of ...
