News release: Division of Boating and Waterways begins control efforts in the Delta for aquatic invasive plants
California State Parks’ Division of Boating and Waterways (DBW) announced today its plans for this year’s Aquatic Invasive Plant Control Program in the Sacramento-San Joaquin Delta and its southern tributaries. Starting tomorrow, March 1, DBW will begin herbicide treatments to control water hyacinth, South American spongeplant, Uruguay water primrose, Alligator weed, Brazilian waterweed, curlyleaf pondweed, Eurasian watermilfoil, hornwort (aka coontail), and fanwort. These aquatic invasive plants have no known natural controls in the west coast’s largest estuary, the Delta. They negatively affect the Delta’s ecosystem as they displace native plants. Continued warm temperatures help the plants proliferate at high rates.
