Thank you for reminding people to replace the rock. In a recent post, I showed some of the damage done to glade habitats south of St. Louis by those who flipped rocks and failed to return them to their original position. In some cases it may not be so important, but it could be critical in others.

When replacing rocks, keep in mind that the act of replacing the rock can still crush invertebrates and even small vertebrates such as lizards and salamanders and destroy previously constructed galleries and nests. Even a small shift in its position relative to the original position can expose previously hidden eggs and other quiescent life stages to predation.

Best regards — Ted
