Sacramento, CA…The Division of Boating and Waterways (DBW) announced today its plans for this year\u2019s control efforts for aquatic invasive plants in the Sacramento-San Joaquin Delta (Delta). Starting March 5, DBW will be controlling water hyacinth, American spongeplant and Uruguay water primrose along waterways entering the Stockton Deep Water Channel via mechanical harvesting. The use of herbicides will start on Monday, March 12 for the following aquatic invasive plants: water hyacinth, Egeria densa, South American spongeplant, Uruguay water primrose, curly-leaf pondweed, Eurasian watermilfoil, fanwort and coontail. Treatment start dates may change depending on weather conditions and plant growth\/movement.<\/p>\n

These aquatic invasive plants have no known natural controls in the west coast\u2019s largest estuary, the Delta. They negatively affect the Delta\u2019s ecosystem as they displace native plants. Continued warm temperatures help the plants proliferate at high rates. Plants are also known to form dense mats of vegetation creating safety hazards for boaters, obstructing navigation channels, marinas and irrigation systems. Due to their ability to rapidly spread to new areas, it is likely that the plants will never be eradicated from Delta waters. Therefore, DBW operates \u201ccontrol\u201d programs as opposed to \u201ceradication\u201d programs. The division works with local, state, and federal entities to better understand the plants and implement new integrated strategic methods and increase efficacy.<\/p>\n

\u201cDBW recognizes the impact of these aquatic invasive plants on people\u2019s daily lives and businesses,\u201d said DBW\u2019s Acting Deputy Director Ramona Fernandez. \u201cIn an effort to minimize the impact, we continue to leverage technology and resources through collaboration and cooperation with the public and our local, state and federal partners who are helping us manage this challenge.\u201d<\/p>\n

All herbicides are registered for aquatic use with the U.S. Environmental Protection Agency and California Department of Pesticide Regulation. Treated areas will be monitored to ensure herbicide levels do not exceed allowable limits and that herbicide treatments have no expected adverse impacts on the environment, agriculture or public health in or near the planned treatment areas. The public may view the public notices and sign up to receive weekly updates on this year\u2019s treatment season on DBW’s website.<\/p>\n

Mechanical Harvesting<\/p>\n

This type of control method is not used for submersed aquatic vegetation. These plants spread by fragmentation. Cutting the plants back exacerbates the problem, as shreds of the plants float away and re-propagate.<\/p>\n

Last year, DBW treated 3,023 acres (210 sites) of floating aquatic vegetation and 2,967 acres (46 sites) of submersed aquatic vegetation. Mechanical harvesting efforts totaled 8.08 acres. The division anticipates 2018 to have drier conditions compared to 2017 and treatment of aquatic invasive plants up to 10,400 acres. A combination of herbicide, biological and mechanical control methods will be used to help control invasive plants at high priority sites in the Delta.<\/p>\n

Funding for DBW\u2019s aquatic invasive plant control programs comes from the Harbors and Watercraft Revolving Fund, which receives revenues from boaters\u2019 registration fees and gasoline taxes.<\/p>\n

In 1982, California state legislation designated DBW as the lead state agency to cooperate with other state, local and federal agencies in controlling water hyacinth in the Delta, its tributaries, and the Suisun Marsh. The Egeria Densa Control Program was authorized by law in 1997 and treatment began in 2001. In 2012, Spongeplant was authorized for control upon completion of the biological assessment. In 2013, DBW was able to expand its jurisdiction to include other invasive aquatic plants, and since then other aquatic invasive plants such as Uruguay water primrose, Eurasian watermilfoil, Carolina fanwort and coontail have been added to the AIPCP program.<\/p>\n
