SciencePhoto: HT WorldWeeping Lovegrass Planted in 1935 to Control Erosion in Oklahoma
Weeping lovegrass, an African grass introduced in 1935 at Stillwater, Oklahoma, was planted to prevent soil erosion during the drought-stricken 1930s American Plains. It formed dense root mats that stabilized soil and was also used as animal feed. One strain, A-67, spread widely, covering 2 million acres. Later studies found that it reduced plant diversity in the areas it colonized.
