Mil Cumbres IBA embraces a complex landscape within the municipalities of Los Palacios, La Palma and Bahía Honda, in Pinar del Río province. The landscape comprises agricultural plains, karst valleys, mojotes, slate cliffs, sinkholes, sulphur springs and hills, and includes the Sierra de los Órganos, Sierra del Pan de Guajaibón, and the Cajálbana Plateau. The IBA protects an important aquifer and the catchment areas of the San Marcos and San Diego rivers.
This IBA supports 32 biome-restricted species, 15 of which are Cuba endemics and 11 globally threatened birds. The Endangered Blue-headed Quail-dove Starnoenas cyanocephala, Giant Kingbird Tyrannus cubensis, and Gundlach’s Hawk Accipiter gundlachi occur and the area is particularly important for the Vulnerable Fernandina’s Flicker Colaptes fernandinae, and Near Threatened Painted Bunting Passerina ciris, Cuban Solitaire Myadestes elisabeth, and Plain Pigeon Patagioenas inornata.
Non-bird biodiversity: The herpetofauna includes the Critically Endangered frog Eleutherodactylus symingtoni and other Pinar del Río endemics Anolis vermiculatus and A. bartschi. Mammals include the hutias Mysateles prehensilis and Capromys pilorides, and 10 bat species. Two locally endemic freshwater fish are also present. Of a flora with 1,143 species, 52 are endemic to Cajálbana and 24 to Sierra de la Güira.
