Weed Management Areas

County-based Weed Management Areas (WMAs) have formed in every part of the state. Follow the links below to learn more about each WMA, or see background on the WMA program. Links go to the WMA’s own website if it has one or to a simple profile on our website. Help us keep these profiles up to date! Notify us of any changes by emailing info@cal-ipc.org.

We encourage you to contribute observations of regional EDRR weed species!
