Mad River Biologists is a consortium of biologists founded in 1982. We perform wildlife inventory and assessment work, botanical surveys, wetland delineation, training in wildlife survey and identification, and development and implementation of wildlife management projects throughout Northwestern California.

Our mission is to conduct research, education, and management projects to support the conservation, protection, and recovery of natural ecosystems and their inhabitants by performing biologically sound work, empowering our biologists to use their special talents, employing effective communication within our organization and to our colleagues and clients, and respecting the lives of our employees and our colleagues.
