This article from Science discusses a new species of crayfish (not just recently discovered, but an actual new species) that is self-cloning and highly invasive. It's not a weed, but it acts like one...

Biological control of water hyacinth in the Delta is being developed as part of an integrated, adaptive management plan for sustainable, long-term control of water hyacinth. Water hyacinth is one of the most troublesome floating aquatic weeds in the Delta, and one of the key targeted species in the USDA-ARS-funded Delta Region Areawide Aquatic Weed Project (DRAAWP). Biological control can greatly assist the weed control program managed by the Division of Boating and Waterways-California Department of Parks and Recreation (DBW). Before biocontrol can be fully implemented, the control plan must be reviewed by the U.S. Fish and Wildlife Service (USFWS) and the NOAA-National Marine Fisheries Service. USFWS is responsible for protecting...

Controlling invasive aquatic plants such as waterhyacinth, South American spongeplant, and waterprimrose in the Sacramento-San Joaquin Delta is no easy task. To address these species of floating aquatic vegetation (FAV), the California Department of Parks and Recreation, Division of Boating and Waterways (DBW) implements an integrated pest management program using a combination of chemical and mechanical control methods.
Historically, herbicide treatment was the primary tool used by DBW to control FAV. Starting in 2013, mechanical harvesting of FAV was integrated into DBW's control program. By 2016, DBW was able to conduct mechanical harvesting almost continuously throughout the year in various locations of the...
