[2][3] Prairie remnants are present on the south-facing ridge and have recovered from previous agricultural use due to intensive management that began in 1995.

Other plants include silky rye, bottlebrush grass, ear-leaved brome, leadplant, large-flowered yellow false foxglove, Canada milk-vetch, Illinois tick-trefoil, alum-root, shooting star, and spiderwort.

Other rare plants present are the state-threatened giant yellow hyssop (Agastache nepetoides), and special concern upland boneset (Eupatorium sessilifolium).

Spring ephemerals are abundant here, including bloodroot, Jacob's-ladder, large-flowered bellwort, yellow lady's-slipper orchid, large white trillium, and dutchman's breeches.

Pleasant Valley Conservancy is owned in part by The Prairie Enthusiasts and by Tom Brock and his wife Kathie with management support from the Savanna Oak Foundation.
