Sierra de Manantlán Biosphere Reserve, Biosphere reserve between Colima and Jalisco, Mexico.
The Sierra de Manantlán is a biosphere reserve situated in the Sierra Madre del Sur, spanning across two states with varied terrain and ecosystems. The landscape transitions from misty cloud forests at higher elevations to tropical woodlands in lower areas, with intermediate zones showing diverse plant and animal communities.
The protected area was established in 1987 when Mexican authorities designated it to safeguard its forests and water sources for future generations. UNESCO granted it biosphere reserve status the following year, giving it international recognition as an important natural zone.
The name Sierra de Manantlán comes from Nahuatl, meaning "place of springs," reflecting the many water sources flowing through the region. Local communities recognize the reserve as vital for their water supply and have traditional connections to these protected forests.
Visitors should wear good hiking shoes as trails cover varying elevations and changing terrain throughout the reserve. It helps to arrive early and consider hiring a local guide to explore safely and make the most of wildlife observation opportunities during the quieter morning hours.
Scientists discovered a rare wild maize species called Zea diploperennis in the region during the 1970s, and it still grows here as a living link to ancient farming practices. This species survives in only a handful of places worldwide and has been under careful protection to preserve its genetic diversity for the future.
