The Brookfield Oak Savanna is an open woodland habitat between grasslands and forests. Oak savannas were a large part of the American landscape for many centuries, but today they are one of the rarest ecosystems in the world. They are part of our natural heritage and need protection. The Brookfield Oak Savanna has a wide variety of plants native to this area, and these plants provide food and shelter that attract and sustain native animals, including Cooper's hawks, redheaded and downy woodpeckers, butterflies, chipmunks, and migrating songbirds.
