Abstract
The objective of this research was to develop and demonstrate native grass sod for sediment control from disturbed lands associated with California highways. The research evaluated native grass species for inclusion in sod and evaluated the sod at a California highway field site. Seed mixes, including rhizomatous and bunchgrass species, were evaluated in a greenhouse setting for six California ecoregions. Growth and sod development potential of each seed mix for each ecoregion were evaluated. Seed mixes for three California ecoregions were further evaluated with a reinforcement material, and for establishment and weed suppression. Establishment and weed suppression of select ecoregion seed mixes and reinforcement materials were evaluated. Results indicated that multispecies sod has potential for use in revegetation of disturbed lands associated with highways.
