San Pedro Mártir
San Pedro Martir is the most isolated island in the Gulf of California, located right in the center, 51 km from the Baja California peninsula and 53 km from the coast of Sonora. The island was declared a Biosphere Reserve in 2002 and in 2005, along with another 244 islands, decreed a World Heritage Site. San Pedro Martir is an oasis; most notably in its land portion there is a cacti forest and breeding colonies of hundreds of birds, mainly brown booby (Sula leucogaster) and blue-footed booby (S. nebouxii). The coastal part houses the third largest colony of sea lions (Zalophus Californian) in the Gulf of California. And in the ocean, a great diversity of ecosystems such as kelp and rhodoliths, rocky reefs, and coral forests abound. Around the island one can observe families of sperm whales (Physeter macrocephalus).
