Description: 
The effects of prescribed fire and livestock grazing on a semi-arid grassland community dominated by the non-native invasive grass, Lehman lovegrass (Eragrostis lehmanniana Nees) were evaluated at the Santa Rita Experimental Range (SPER) 50 km south of Tucson, Arizona (31� 82� N; 110� 88� W). Prescribed fire and grazing were applied to half the plots in the summer of 2005 and the second half in the summer of 2006. Two grazing treatments (present of absent) were applied seven weeks after prescribed fire to a utilization rate of 80%. Plant species composition and cover was estimated every fall and spring using the point-intercept method while vegetation production was collected every fall.
