The Riparian Improvement Organization (RIO) was established in 1993 as a non-profit organization located in Davis, CA. 

RIO recognizes that there are several environmental organizations operating to better California through legislative and legal avenues. In light of these efforts, RIO identified the need to also develop and conduct projects that physically improve the environment.  

We promote projects that require a “hands-on” approach that will provide a tangible benefit to the environment. A few examples of these projects can be seen in the Past Projects section. Volunteer affiliates often come from the local community, but larger multi-site events usually attract volunteers from all areas of California.  

RIO looks for “hands-on” projects to participate in or coordinate on an on-going basis. If you know of a project or location that can use our help, please Contact Us.
