UNESCO: Gulf of California Islands and Protected Areas

Cabo San Lucas - UNESCO Natural World Heritage Site
Cabo San Lucas is part of the UNESCO Natural World Heritage Site - the Gulf of California Islands & Protected Areas.

A UNESCO Natural World Heritage site since 2005, the Gulf of California Islands & Protected Areas are comprised of 244 islands, islets, and coastal areas that are located in north-eastern Mexico on the Gulf of California. The area is striking - full of natural beauty in a setting made up of rugged islands with high cliffs and sandy beaches which contrast with the brilliant reflection from the desert and surrounding turquoise waters.

According to UNESCO, the Sea of Cortez and its islands have been called a natural laboratory for the investigation of speciation. Nearly all major oceanographic processes that occur in oceans are present at the site. It is home to 695 vascular plant species (more than in any marine and insular property on the World Heritage List). Equally exceptional is the number of fish species: 891, 90 of them endemic. The site contains 39% of the world’s total number of species of marine mammals and a third of the world’s marine cetacean species.
