Project Summary

This research was designed to identify how potential “native winner” species perform in post-fire revegetation conditions where cheatgrass is present, relative to the native species and sources that are currently available. We also tested whether the ratio of grasses to forbs impacts the outcome of revegetation efforts in habitat degraded by cheatgrass. For this, we worked with the BLM Grand Junction Field Office (GJFO) following the July 2012 Pine Ridge Fire to establish three study blocks at a site with high percent cheatgrass cover, and monitored percent cover of sown and spontaneous plant species in all blocks in May and September 2013, June 2014, and May 2016. We aimed to identify which of the “native winner” species we sowed are able to germinate, establish, and persist at the site, and compare this with species and sources in the GJFO’s Broad Site seed mix. Ultimately, our goal was to help identify seeding sourcing approaches that can improve the long-term outcomes of revegetation efforts in cheatgrass-degraded habitat.
