The Delta Region Areawide Aquatic Weed Program has been focusing science and the application of science onto the management of invasive aquatic weeds such as water hyacinth, Brazilian egeria, and water primrose in the Delta. As part of the conclusion of the DRAAWP, a special session has been organized for the 2019 Joint Annual Meetings of the Aquatic Plant Management Society and the Western Aquatic Plant Management Society (http://www.apms.org/annual-meeting/2019-annual-meeting/).
