El Vizcaíno Biosphere Reserve, Mexico
"Midway down the Baja California Peninsula lies a land- and seascape that the United Nations Educational, Scientific, and Cultural Organization (UNESCO) has declared a World Heritage site and a Biosphere Reserve. Encompassing two lagoons and a large stretch of land between them, El Vizcaíno Biosphere Reserve provides a winter home for gray whales and other marine mammals, and habitat for thousands of migratory waterfowl. Plant life includes Sonoran Desert vegetation and, at the water’s edge, mangroves."
