Tehuacán-Cuicatlán Valley

MEXICO

Located in the Mesoamerican region, this area has the richest biodiversity in all of North America and is one of the main centres of diversification for the cacti family, which is endangered worldwide. The valley harbours the densest forests of columnar cacti in the world, shaping a unique landscape that also includes agaves, yuccas and oaks. Archaeological remains demonstrate technological developments and the early domestication of crops.
