We conducted a field experiment to assess effects of simulated above-average fall and spring precipitation on monoculture performance and competitive relations of the exotic annual grass Bromus tectorum and the native bunchgrass Stipa hymenoides in southeastern Utah. Between 1 October 1997 and 31 May 1998, "wet" plots received 239 mm and "dry" plots received 119 mm of water representing 175 and 87 percent of average precipitation, respectively. In monoculture, added water increased fall Bromus establishment by a factor of 1.6 but did not affect fall or winter growth. Added water adversely affected Bromus growth during early spring, but enhanced growth as soils dried during mid-spring. Overall, Bromus shoot production...
