How to Recognize It
This lush and diverse natural community occurs on some moist and fertile slopes bordering the Potomac floodplain. The concave (dish-like) shape of these slopes helps them retain moisture. In addition, the fact that they face north to northeast reduces their exposure to the drying rays of direct sunlight. Nutrients are provided by the underlying geology, infrequent floods, and possibly groundwater seeps. Unfortunately, no sites are accessible to the public in Harpers Ferry National Historical Park.
Can you find this combination of key features?
