Sierra de las Minas Biosphere Reserve
Zacapa
The Sierra de las Minas Biosphere Reserve is a significant mountain range extending 130 km west of Lake Izabal in eastern Guatemala. It spans 15 to 30 km in width, bordered by the Polochic River valley to the north and the Motagua River valley to the south, with the Salamá River valley marking its western boundary. The highest peak, Cerro Raxón, rises to 3,015 meters. This range is renowned for its rich deposits of jadeite and marble, which have been mined for centuries, giving the mountain range its name. The reserve encompasses a wide variety of habitats due to its varied elevation and precipitation, including subtropical thorn forests, premontane dry and wet forests, lower montane moist forests, and extensive cloud forests, which are among the largest in Mesoamerica. It supports an impressive biodiversity of 885 species, including threatened birds such as the resplendent quetzal, harpy eagle, and horned guan, as well as large felines like jaguars and cougars. The biosphere reserve was officially designated in 1990, covering an area of 2,408 square kilometers, including buffer and transition zones. Besides its ecological importance, the area holds cultural significance as a historical source of jadeite used by Pre-Columbian civilizations such as the Olmecs and Maya for ritual and ornamental purposes, contributing to ancient Mesoamerican trade networks.
