Arundo donax (Giant Reed) is a noxious weed that can infest and dominate watersheds including the Santa Clara River watershed (SCRW). Surveys completed by the California Invasive Plant Council found that the SCRW is one of the top three in terms of abundance and extent of invasive Arundo. Arundo grows incredibly fast and creates large dense stands that create many problems for the ecosystem and wildlife in the area. Native vegetation, like willows, have a hard time competing against Arundo, lessening biodiversity, habitat for fish and frogs, and inhibiting the natural flow of the river. Much of the adjacent land to the Santa Clara River is used for agriculture, which is a significant economic driver for Ventura County. Additionally, many municipal areas along the river are expanding, increasing the population that lives on the wildland urban interface. A. donax not only creates a huge fire hazard to the ecosystem and surrounding communities, but it also consumes much more water than native species, almost four times the amount.
