Weed Management

Santa Ana River and Orange County Weed Management Area

The Santa Ana River and Orange County Weed Management Area (SAROCWMA) was formed in 2003 with the objectives of controlling Pepperweed and other outlier weed populations in the Santa Ana River watershed.

SAROCWMA coordinates weed management activities to help prevent and control the spread of invasive weeds on both private and public lands. These activities include locating and reducing the range of invasive weeds, identifying and removing newly emerging weed populations, and educating the public about the issues associated with invasive weeds.

The group has been successful at controlling common invasive plants, including perennial pepperweed, Tamarisk (salt cedar), poisonous and invasive castor bean, and Arundo donax (giant reed) in Riverside, San Bernardino and Orange Counties.
