Revegetation of exotic annual grass-invaded rangelands is challenging with high rates of failure.� Successful revegetation starts with effective control of exotic annuals.� Effective control may require integrated treatments.� Following control, high establishment of perennial vegetation is critical to limiting re-invasion by exotic annuals.� However, establishment of perennial vegetation can be low, especially with native species.� Introduced perennial bunchgrasses establish more reliably and compete better with exotic annuals than native bunchgrasses on drier sites.� However, on cooler and wetter sites or with above average precipitation, native perennial vegetation may establishment in high enough numbers to limit exotic annual grasses.� New technologies may improve revegetation success.� For example, activated carbon pellets can be used to protect seeds incorporated within from pre-emergent herbicide damage.� This allows desired species to be seeded at the same time exotic annuals are controlled with pre-emergent herbicides.� Successful revegetation of exotic annual grass-invaded rangelands will require continued research to provide longer-term control of annuals and improve the establishment of seeded vegetation.
