Sierra del Rosario

Sierra del Rosario Biosphere Reserve is located in the western provinces of Pinar del Río and Artemisa in Cuba, covering approximately 25,000 hectares of montane forest in the western cordillera of the island. Designated as Cuba's first UNESCO Biosphere Reserve in 1984, the reserve protects a mosaic of montane rainforest, semi-deciduous forest, pine forest, and wetland habitats. It serves as a crucial biodiversity corridor in western Cuba and is one of the best-studied protected areas on the island. The reserve integrates a core zone of strict conservation with surrounding buffer and transition zones where sustainable land use is practiced.
