Article abstract: The Brachypodium Phase II project treated 19.5 acres of Brachypodium-infested habitat, and compared monitoring methods and treatment effectiveness on the Crestridge Ecological Reserve and South Crest Preserve in San Diego County, California. This project continued treatments initiated under the Brachypodium Phase I project. The San Diego Association of Government (SANDAG) Transnet Environmental Mitigation Program provided grant funding for both projects. Phase II objectives included (1) monitoring treatment areas, (2) assessing monitoring methods, (3) reducing nonnative species cover through herbicide application, and (4) refining Best Management Practices (BMPs) for Brachypodium control. We monitored treatment areas (native species richness, cover) quantitatively in 2016 and semi-quantitatively in 2016 and 2017, and continued herbicide treatment of Brachypodium and nonnative grasses and forbs in all Phase I treatment areas.
