Shifting Sands on Petit Bois Island

Wilderness impacted by human activities

Petit Bois is an officially designated wilderness area. The National Park Service manages Petit Bois as part of the Gulf Islands National Seashore to retain its “primeval” character – a term identified in the Wilderness Act – and permits no permanent human structures and no motorized vehicles as part of this wilderness – mandate. But Park Rangers can’t control the human activities that happen outside park boundaries. Human activities that alter the island’s natural processes – including dredging and climate change — involve other government agencies, people who use the barrier islands and local ports, and everyone around the world contributing to greenhouse gases.
