Descripción: UNESCO, MAB Biosphere Reserves Directory.
«The Sierra del Rosario Biosphere Reserve is located at the eastern part of the mountain range of Guaniguanico, between Pinar del Rio and Havana’s provinces of Cuba, where both north and south coasts can be seen. It covers an area of 26,686 hectares. This reserve shows a complex geological structure, with a great diversity of rocks that produce different and special soils, which in part, determine flora endemism in its landscape.»
