The four expedition bases have such an important part in the world's history the Antarctic Treaty System (which governs international activity in Antarctica) has listed each of the bases as Antarctic Specially Protected Areas (ASPAs) - the highest possible protection listing available.
As a result of the listing a permit to visit is required and management plans and a Code of Conduct have been prepared to help protect the sites.
