The American River Natural History Association is a non-profit volunteer organization that has operated the Effie Yeaw Nature Center since July 4, 2010, when ARNHA took over financial responsibility for the Nature Center from Sacramento County. ARNHA and the Nature Center rely on funds from members, donations, and grants. We appreciate your support.
