At the center of this reserve is the largest limestone cave and the richest fossil site in Hawaii. The reserve is also a uniquely preserved archaeological site and a living museum to the past and to the future. On abandoned farms and quarry lands surrounding the cave, native plants and animals have returned through innovative restoration techniques. Acres of restored forest land, dune vegetation, and wetland habitat feature almost 100 species of native plants, including many endangered species, as well as endangered waterbirds and an underground ecosystem of blind cave invertebrates.
