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 more specifically the Salinas River, exacerbating flood prone areas [5]. The dense stalks of Arundo change direction of water flow, change the force of the river, and increase flood risk [6]. Salinas River has a long history of floods, with the most recent flood forecasted in February of 2017, after heavy rain [7]. river water used by arundo flood probability flood history
