Explore Missouri's original landscapes

Missouri's natural areas represent some of the best — and last — examples of our state's original landscape. Here are places where you can still see the rare plants, animals, and geological features that pre-settlement native Americans knew well or that explorers such as Lewis and Clark observed and recorded. Explore remnant prairies, old-growth forests and woodlands, rare wetlands, caves, and many other kinds of native habitat.
