The proposed project involves the application of herbicides on invasive species in areas of degraded grassland habitat to test optimal invasive species control options. The project targets the control of invasive grasses and weeds in the Chino Hills area and control of stinknet in Perris. at the project sites, no bodies of water or other environmentally sensitive areas are nearby. Application of the herbicide would take 2 to 5 days per year. Application of the herbicide will be conducted by a licensed herbicide applicator in accordance with all applicable regulations and would take place from 2015 through 2018.
