El Cielo Biosphere Reserve
Northeast Mexico Region
El Cielo Biosphere Reserve, located in the Sierra Madre Oriental of Tamaulipas, Mexico, spans over 144,000 hectares featuring steep mountains rising from 200 to over 2,300 meters. It protects the northernmost tropical and cloud forests in Mexico, housing diverse ecosystems ranging from desert shrublands to lush cloud forests. Established as a protected area in 1985 and declared a UNESCO Biosphere Reserve in 1987, it offers a rare glimpse into varied altitudinal climates and karst topography characterized by caves and sinkholes. The reserve includes two core zones with restricted human activity to preserve its ecological integrity, surrounded by buffer zones where limited sustainable use is allowed. Visitors can explore communities like Alta Cima, which provide lodging and dining, and enjoy facilities such as an ecological interpretive center offering panoramic views of tropical forests. The reserve is a critical site for biological research and conservation, maintaining habitats for numerous plant and animal species unique to this region.

History
The El Cielo area remained largely unnoticed until the 1930s when Canadian horticulturalist John William Francis Harrison established Rancho El Cielo in the cloud forest.
Ornithologists and biologists such as George Miksch Sutton and Paul S.
Martin conducted significant fieldwork here from the 1930s to 1950s, contributing to the understanding of the region's biodiversity.
Logging and road construction threatened the area in the mid-20th century, prompting Harrison to transfer his land to a non-profit in 1965 to protect the ecosystem.
The site was officially protected by the state in 1985 and recognized as a UNESCO Biosphere Reserve in 1987.
Harrison's former ranch now serves as a biological research center, continuing the legacy of conservation and scientific study.
