Observation Narrative
A small, but representative example of a dry greenstone outcrop characterized by a patchwork of shrubs, herbaceous lithophytes and exposed bedrock. Periodic droughts and generally stressful substrate conditions keep invading woody plants such as Fraxinus americana and Juniperus virginiana var. virginiana in a stunted, poorly reproducing condition.
About 80 m north of Greenstone Overlook on Blue Ridge Parkway, near Humpback Rocks Picnic Area. Plot located just below interpretive trail where it crosses the open rock outcrop.
