Upper Los Angeles River Watershed Arundo donax Eradication Program

Document Description
Project Specific Analysis/Addendum to PEIR for this project: In partnership with parallel efforts occurring in the Tujunga Wash, Council for Watershed Health will eradicate ~80 acres of Arundo (Arundo donax;common name giant reed) in the Upper Los Angeles River Watershed. Arundo stands will be treated using best management practices and will be controlled using aquatic approved herbicides by licensed contractors. An integrated pest management process will be used that minimizes herbicide amounts and uses alternatives where appropriate. Most stands will be foliar treated with backpack sprayers, while canes would be bent and treated. All efforts will be made to minimize any impacts to other adjacent vegetation. Marking dye will be used to ensure treatment coverage and minimize drift. At the request of property owners, small Arundo stands near roads or structures may be cut, hauled, and chipped at an offsite location, away from riparian areas and other vegetation, and cut stumps would be treated. Chipped Arundo biomass may be spread in the stand footprint, over disturbed areas.
