Once lost beneath a tangle of invasives, Hidden Prairie emerged after years of careful restoration. The northern portion ranges from wet prairie to swamp to marsh to open water. The prairie features a variety of native grasses and rare wildflowers.

The southern portion (Ivory) is a large marsh under restoration. The wetlands host great egrets, great blue herons, green herons, wood ducks, and other water birds.

Access to the preserve is by special permission or guided tour only, due to the sensitive nature of the high-quality prairie remnant.
