Shale barren communities are very rare in Illinois. This barren remnant is located on an outcrop of Springville Shale in Union County. The trees of this site are dwarfed and open grown, particularly post oak. Blackjack oak, white oak, shingle oak, and red oak also occur at this site. Little bluestem is the most common grass in the understory which is naturally depauperate due to the dry conditions of the site. Curly muhly grass is common in the barrens.
