Some invasive foreign weeds have been singled-out by California as being exceptionally detrimental to agriculture and wildlands. The Sutter County Pest Eradication Program is responsible for identifying these noxious weed populations and assuring that those populations are eliminated.

Agriculture department staff educate and encourage landowners to aggressively remove these invaders; species that are proven to overrun crop, pasture and rangeland, or invade forests, riparian corridors, estuaries and other natural habitats. These plants often taint crops such as hay, costing millions of dollars annually to farmers. In many situations, they create a monoculture throughout an entire ecosystem, displacing many of the native inhabitants.

Responsible landowners often choose to eliminate the populations themselves. In such cases, we gladly assist with identification and information that will allow them to make informed decisions about courses of action.

Noxious Weed Program

The Noxious Weed Information Project (NWIP) is a part of Integrated Pest Control, a branch of Plant Health and Pest Prevention Services which is a division of the CDFA. Current activities include collecting and processing data on current weed management projects that are focused primarily on A-rated weeds. NWIP provides maps and other information for CDFA, biologists and the general public. Go to the CDFA website and learn more by clicking the links below.
