Cactus-like vegetation, including serpentine aster and round-leaved fameflower, thrived in the dry landscape and even perpetuated it with their flammability.
The Nature Conservancy has worked to protect globally rare serpentine barrens since 1979, when it joined Chester County’s “Concerned Citizens of West Nottingham Township” to oppose the quarrying of serpentine rock near the Goat Hill Barrens.
A similar agreement exists with a private landowner at the New Texas Barrens in Lancaster County, where the Conservancy conducts ecological restoration and habitat improvement to ensure the unique barren habitats still in existence, continue to thrive.
