Goats seen eating aquatic weeds
In late October we made our monthly trip to sample curlyleaf pondweed in the Sacramento-San Joaquin Delta. On an island in the lower San Joaquin river, we spotted goats eating waterhyacinth (Eichhornia crassipes) and waterprimrose (Ludwigia sp.) along...
Biological control of invasive water primroses
Exotic water primroses (Ludwigia spp.) are aggressive invaders in both aquatic and riparian ecosystems. The plants form dense mats over the water surface. These mats constrain navigation and interfere with recreational activities, irrigation, drainage,...
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...
