The Engineer Research and Development Center (ERDC) of the U.S. Army Corps of Engineers (USACE) is offering a funding opportunity for research focused on the biological control of the invasive plant Arundo donax in Southern California. The initiative aims to evaluate biological control methods, develop effective release strategies for control agents, and assess their impact on the water-use efficiency and biodiversity of A. donax, with the goal of producing management tools to reduce its populations and enhance local ecosystems. This project is significant as Arundo donax poses a substantial threat to water resources and biodiversity in arid environments, with management costs exceeding $250,000 per acre in some areas. The total funding available for this program is $395,000 over five years, with an award ceiling of $120,000 for the first year. Interested applicants, who must be non-federal partners of the Californian Cooperative Ecosystems Studies Unit (CESU), should submit a statement of interest by March 14, 2025, followed by full proposals due by April 14, 2025.
