[from the text] Lehmann lovegrass (Eragrostis lehmanniana Nees.), a drought tolerant, warm season perennial bunchgrass, was introduced to Arizona over 50 years ago (Cable 1971). It now covers over 200,000 ha in southeastern Arizona (Cox and Ruyle 1986). This grass provides important cover for erosion control and forage for livestock on many southwestern rangelands lacking native perennial grass cover. However, Lehmann love grass is not evenly utilized by grazing animals due to its stemmy habit (Ruyle et al. 1987) and its invasion into native grasslands may decrease biological diversity (Bock et al. 1986). Fire has been considered as a management tool to address both of these concerns.
