Arundo wasp, a biocontrol agent, is established and spreading in Delta watersheds
Arundo or giant reed (Arundo donax) is invasive in riparian areas in much of central and southern California, as well as other parts of the U.S. In the Sacramento-San Joaquin Delta, arundo grows on islands and along the edges of sloughs and canals. It is...
California Division of Boating & Waterways teams up with NASA to map invasive aquatic weeds
Through a partnership with National Aeronautics and Space Administration (NASA), as a part of the U.S. Department of Agriculture – Agricultural Research Service (USDA-ARS) Delta Regional Areawide Aquatic Weed Project (DRAAWP), NASA has developed...
South American spongeplant - basic and applied studies
The Madsen lab is working on South American spongeplant (Limnobium laevigatum), a relatively new invader in the Sacramento-San Joaquin Delta (Photo 1). Spongeplant is a floating aquatic weed that somewhat resembles waterhyacinth and can be found...
The next DRAAWP technical update meeting is Friday, Aug 16, 9 a.m. to noon, in PES 3001, UC Davis.
UC Davis Weed Science School will be Aug 20-22. This short course emphasizes terrestrial weeds but will present information of interest to all invasive plant workers. (The Aquatic Weed School will return next year.)
Our DRAAWP informational brochure is available from the Site Navigation tab at the left.
Progress Reports (February 2018) are available under the Products tab.
