Anderson Marsh Interpretive Association (AMIA) was formed in 1984, after the State of California acquired the Park in 1982. The primary objective of the Association has been to promote educational and interpretive activities at Anderson Marsh State Historic Park. AMIA has played an important role in funding projects that the state would otherwise be unable to provide. These have included conservatory work, construction, trail work, interpretive displays, rehabilitation of facilities and historic objects, purchasing interpretive items, acquiring furnishings and providing literature and other interpretive information. Through the years, AMIA has helped to educate the public about the special and unique place now called Anderson Marsh State Historic Park.
