Erosion control
Eragrostis lehmanniana is widely used for reseeding rangeland because it gives a rapid soil cover (FAO, 2011). It has been widely used for roadside stabilization and range restoration in the Chihuahuan and Sonoran deserts in the United States (Uchytil, 1992).
Weed
Eragrostis lehmanniana tends to crowd out the more palatable native perennial grasses (Cable, 1971) and can become the dominant herbaceous plant within 15 years after adventive establishment (McClaran et al., 1992). In the 1990s, several decades after its introduction in the United States, it had replaced native grasses on 200,000 ha in South-Eastern Arizona (Cox et al., 1990). Its adventitious spread is not affected by grazing intensity. Faunal diversity can be lower in lovegrass-dominated grasslands than in native grasslands (McClaran et al., 1992).
