Arundo donax: Invasive Plant

Giant reed (Arundo donax) is a perrenial invasive grass native to Eastern Asia. It is a persistent rhizomatous grass with high biomass production that was introduced to other continents by humans, for building material since many years [2]. This grass can reach up to 20 feet tall in height when healthy, with long, flat, and green leaves. It is considered an ecological threat since it spreads when its rhizomes come in contact with soil within wetlands. This grass spreads along riparian zones and lake shores, and competes with native vegetation for sunlight, water, and nutrients [3].

Arundo has been spreading through Central California watersheds, and exacerbating flood prone areas [5]. Monterey and San Luis Obispo counties, as well as the San Francisco Bay Area, and Sacramento and San Joaquin River valleys have been impacted with proliferating stands of Arundo Cite error: Closing </ref> missing for <ref> tag. Salinas River has a long history of floods dating back to 1911, with the most recent flooding forecasted in February of 2017, after heavy rains [6]. With high precipitation rates in the area in the winter, proliferating Arundo stalks are further exacerbating flood risks in this region.

Resource Conservation Districts: RCD Monterey County

The two groups that are addressing this encroachment of Arundo in the Central Coast region are the Resource Conservation District, Monterey Bay (RCDMC), and the Monterey County Water Resources Agency (MCWRA). RCDMC is one of the special districts in California, designated to implement and monitor resource conservation projects across private and public land [7]
