ⓘ San Pedro Martir Island
San Pedro Martir is the name of an island of Mexico, located in the Gulf of California, about halfway between the coast of Baja California and Sonora. San Pedro Martir is located in the center of the Gulf of California and is the most remote island in the Sea of Cortez. It is located 51 km from Baja California and 53 km off the coast of Sonora. The island is 2 km long and 1.5 km maximum width, with a total of 2.729 km 2 of total area. The island is uninhabited and is 60 km from Bahia Kino, the nearest city in the state of Sonora on the west coast.
San Pedro martir is also unique in its year-round birds. The island is the only island in the area with a constantly swirling cloud of seabirds. The large population of birds deposits a huge amount of guano on the island, resulting in the white appearance of the island with sparse vegetation. In Golovanova gannets, circulated on the island, using the island as a place for nesting. Sea lion rockery also ring on the island.
The Seri Indians created benches to attract nest building and ease the collection of eggs, the only evidence of human intervention is visible on the island. In the late 19th and early 20th century was heavily mined guano from the Islands and shipped to Europe for use as fertilizer. Mountain boats brought the black rat as an invasive species on the island. Rats were destroyed in the fall of 2007 by spraying rat poison on the island.
San Pedro martir is rarely visited, having near vertical sides, leaving only the questionable good weather mounts in two places. Access to land was near a small isthmus in the South-East of the island, but is now forbidden. In 2005, the island was classified, together with 244 others a world heritage site by UNESCO and is included in Islands and protected areas of the Gulf of California.
