The Riverside Nature Center Association (RNCA) was organized in 1989. It had 276 members, and visionary Susan Sander developed an environmental education program that was presented in Kerr County schools by Kerrville Junior Service Guild members and others.

Many students and adults have participated each year in educational programs at the Nature Center. These classes provide a unique opportunity to foster awareness of plants, animals, ecology and natural resources of Kerr County.
