Thirty-year-old cheatgrass communities were disturbed by experimentally plowing small plots, Cheatgrass, Bromus tectorum L., promptly invaded the plowed plots. Plowing enhanced plant production at the high elevation site, 520 m, but depressed production at the low elevation site, 320 m, during a year of near normal precipitation in 1976. During the 1977 drought, plant production was very low at both study sites, but productivity was most depressed at the low elevation site. Possible factors in the explanation of results are discussed.
