Description
White Rock Land and Water Reserve is an important part of a regional bluff protection effort that involves a 35-miles corridor in southwest Illinois comprised of sites in the Illinois Nature Preserve System. It contains a mosaic of high-quality limestone glade (Grade B) and upland forest (Grade C dry mesic and dry upland) included on the Potato Hill Illinois Natural Areas Inventory Site (INAI #200) in the bluffs overlooking the Mississippi River floodplain. The upland forest comprises most of the site. Woody species typical to the dry-mesic potion include white oak and shagbark hickory, while the mesic upland forests are primarily blackjack oak, post oak, and chinkapin oak. The glade communities contain a variety of forbs, such as the dominant plant species little bluestem and side oats grama, and conservative plants purple prairie clover, New Jersey tea, blazing star, and scurf tea. The site is additionally an important area for birds, especially those sensitive to forest fragmentation and Species in Greatest Conservation Need, as well as for the state threatened and endangered species which inhabit the site.
