This is a link to a blog post I wrote for the UC Davis-USDA Delta Region Areawide Aquatic Weed Project website. The Sacramento-San Joaquin Delta Conservancy (the agency I work for) gets funding from the USDA to control Arundo infestations in the Delta.
Arundo (which I have written about previously here) is a highly invasive plant that causes bank destabilization, increased fire hazard, increased water use, and excludes native plants and animals. The Delta Conservancy has been coordinating with a the Sonoma Ecology Center and the USDA to apply treatments of herbicides and/or insects that are specific Arundo parasites to eliminate Arundo from as much of the Delta as possible. This work began last summer/fall at the Brannan Island State Recreation Area, as site that is owned by California State Parks and which has a lot of Arundo.
