Kenwood Acres Prairie is a large open area of land dominated by grasses, sedges, and other flowering plants without trees. When Ohio became a state in 1803, an estimated 2-4% of it was prairie, and prairies are now the most endangered ecosystem in the United States, with only 1-2% of the original prairies still existing today. Its wildlife and plant life include the red-tailed hawk, the most common hawk in North America, which feeds primarily on small mammals and can dive at speeds of over 120 miles per hour; the monarch butterfly, which feeds only on milkweed plants and is known for its massive fall migration from different parts of North America to California and Mexico; purple coneflower, a native plant that blooms from June to September, attracts many pollinating insects, and provides seeds for birds; the white-footed mouse, a primarily nocturnal animal that can climb and swim, has keen homing instincts, does not hibernate, and stores seeds and nuts for winter; rattlesnake master, a parsley-family plant with a thick stalk and a ball-shaped flower head of tiny white flowers with a honey-like scent; partridge pea, an annual native pea common in prairies that collapses its leaves when touched; the metallic green sweat bee, less than 1⁄2 inch long, which nests in soil and is attracted to the salt in human sweat; and black-eyed Susan, a native wildflower resistant to deer that serves as a food and pollen source for many butterflies, bees, and other insects. Other flora in the area include little bluestem, nodding wild rye, Indian blanket, New England aster, Virginia mountain mint, stiff goldenrod, and great lobelia, while other fauna include katydid, barred owl, American crow, seven-spotted lady beetle, and garter snake.
