Research indicates that a buffer surrounding a playa lake, consisting typically of native grasses and forbs, prevents migration of upland topsoil and farm chemicals into lowland wetlands such as playa lakes and rainwater basins.
The buffers are important to rangeland playas, but are vital when playas are situated in fields under crop production.
