The phenomenon of cheatgrass die-off is a common and naturally- occurring stand failure that can eliminate the presence of this annual grass for a year or more, affecting tens to hundreds of thousands of acres in some years. We designed a study to determine if the temporary lack of cheatgrass caused by die-offs is a restoration opportunity. We seeded native perennial species at three die-offs in the Winnemucca, Nevada area. Native grass establishment in die-offs was almost three times higher in the first season at all sites, relative to adjacent areas without die-off. In the second season, establishment was five times higher in the die-off at two sites, and plants were notably larger in the die-off at the third site. Increasing seed rates led to more seedlings establishing in both die-offs and controls, with the strongest effect in the second season. We suggest that landowners and managers consider targeting die-offs as efficient locations to focus native restoration efforts, and that restoration practitioners should consider increasing seeding rates to maximize success.
