Arundo donax (giant reed) a highly invasive riparian plant has been designated as one of the top 100 Worst Invasive Species of the World by the Invasive Species Specialist Group of the World Conservation Union (IUCN). Arundo is found infesting waterways throughout much of coastal and central CA from the Mexico border to as far north as southern Humboldt County.

Arundo has significant negative impacts on water availability, water quality (i.e. sediment loads, temperature, pathogens, nutrient loading, flow modification), habitat, fires, and infrastructure and transpires water at a rate that is 5x higher than native vegetation.

The Arundo Eradication Program will plan for, permit, and initiate the removal of ~48-60 acres of Arundo donax from the San Gabriel River (SGR) Watershed. Targeting Arundo populations strategically from the top of the watershed down will eliminate future opportunities for reestablishment and expansion.
