Lehmann lovegrass, a perennial grass native to South Africa, was introduced to Arizona in 1932 to restore damaged rangeland. Between 1940 and 1980, it was planted on over 172,000 acres by ranchers and land managers. By 1988, the grass had spread to dominate about 347,000 acres, mainly in southeastern Arizona, impacting native plant species.
