The Program led by the Council for Watershed Health focuses on removing the invasive, water-intensive Arundo donax (giant reed) from critical areas within the watershed, including the City of Los Angeles and the surrounding San Gabriel, Santa Susana, and Santa Monica Mountains. Arundo transpires water at five times the rate of native plants, significantly impacting water resources, quality, and habitat. By removing Arundo, this project aims to restore approximately 82 acres, improving water availability for downstream capture/recharge and in-stream flow, with each acre cleared providing 20 acre-feet per year of water savings. The eradication will also reduce fire risks and promote the recovery of native vegetation and wildlife habitats.
