Tehuacán-Cuicatlán Valley: Originary Habitat of Mesoamerica, World Heritage Site (Mexico)

The Tehuacán-Cuicatlán Valley is a semi-arid zone with the richest biodiversity in North America, hosting the densest forests of columnar cacti in the world. Archaeological evidence demonstrates the early domestication of crops and an exceptional water management system of canals, wells, aqueducts and dams.
