Description
The Centreville Barrens were the only significant serpentine barrens in Delaware, and were extensively botanized by Albert Commons, who farmed nearby. It was largely submerged after the construction of the Hoopes Reservoir in 1932. A few fragments of serpentine still exist near the reservoir on private property with a few characteristic serpentine flora.
