The Annett Nature Center, sitting in the Annett Nature Center Park, opened on Earth Day in 1997. The result of years of planning and work by the Warren County Conservation Board, and the foresight and benevolence of Warren County Citizens such as Ellis Annett, the ANC is an approximately 9,500 square foot building on three levels sitting in the 160 acre ANC Park. The ANC sits on a hillside above a six acre pond and a ten acre wetland and is adjacent to Lake Ahquabi State Park. The ANC was also built with proceeds from the sale of the Warren County Farm and with REAP (Resource Enhancement and Protection) funds.
