Site description Magens Bay is located on the north central coast of St. Thomas, opens northwesterly into the Atlantic, and includes an extensive sandy beach, coastal mangrove wetlands, and deciduous dry and moist forests. Within the site is Magen’s Bay Preserve, a 129 hectare preserve co-owned and managed by The Nature Conservancy, the Magens Bay Authority and the V.I. Territorial Government. The Preserve, established in 2002 by The Nature Conservancy, includes a modest arboretum, public beach, and nature trail. The land area around the bay is subject to intense development and disturbance from residential areas, a golf course, and recreation. Because of the natural features of the bay area and the district’s unique archeology, the Territorial Government has further designated Magens Bay Preserve as an Area of Particular Concern (APC).
