The effects of defoliation, compaction, nutrient return, and season of use were examined on three study areas (Willow Creek, approximately 16 km north-northwest of Brogan, Oregon, Valley Creek located 6 km northwest of Stanley, Idaho, and Stanley Creek approximately 6 km northwest of Stanley, Idaho). Four defoliation treatments (no defoliation, 10-cm, 5-cm, and 1-cm stubble height) were applied in either spring/mid-summer, late summer/fall, or spring and fall. Two compaction treatments (compaction, no compaction) were applied the same time as clipping. A mixture of manure and urea was applied to designated plots in the Valley Creek area to test for the effect of nutrient return on the plant community. Plant height, biomass response, and soil response were examined on a low-elevation, redtop (Agrostis stolonifera) site in Oregon, and on two, high-elevation, mountain meadow (Carex spp.) sites in Idaho.
