Giant Reed (Arundo donax), believed to be native to the Mediterranean region, has become an invasive species in various parts of the world, including the Southwestern United States. This aggressive plant species poses a significant ecological threat due to its rapid growth, which can lead to the displacement of native vegetation, alteration of stream channels, and increased fire risk. Managing Giant Reed involves a comprehensive approach, including prevention, early detection, and control strategies. Control methods may encompass mechanical removal, targeted herbicide application, and follow-up monitoring to prevent its re-establishment.
