 The agency has been monitoring the refuge to see if any Indiana bats have begun to use dead trees as roosting sites or begin to forage on the site.While the refuge is protected primarily for the bird life, several rare or uncommon plant species have also been found in the grasslands, where Kentucky bluegrass is the dominant species Frank's sedge, small-flowered agrimony, purple milkweed, small white aster, Bush's sedge, coontail and watermeal.A few tree species, such as white ash, American elm, eastern red cedar, and pin oak, also flourish in those sections.
