Alejandro de Humboldt National Park
Cuban national park with high endemism and UNESCO status.
Alejandro de Humboldt National Park, located in the Cuban provinces of Holguín and Guantánamo, bears the name of the German scientist Alexander von Humboldt, who explored the island in 1800 and 1801. It became a UNESCO World Heritage Site in 2001, recognized for its extensive size, broad elevation range, intricate rock formations, varied landscapes, and high concentration of endemic species.
The park’s rivers, flowing from its peaks, rank among the largest in the insular Caribbean. It is considered the wettest place in Cuba, a condition that fosters exceptional biological diversity. Covering 711.38 square kilometers—685.72 of land and 22.63 of sea—its elevations stretch from sea level to 1,168 meters at El Toldo Peak. Geologically, the area is complex, with karst landscapes formed from Cretaceous oceanic crust. The terrain is ultrabasic, dominated by serpentine soils and peridotites, which are relatively toxic to plants and have driven rapid speciation.
This region served as a Pleistocene refugium, maintaining a stable climate through glacial cycles, which allowed for high endemism and biodiversity. The park protects 16 of Cuba’s 28 endemic plant species, including *Dracaena cubensis* and *Podocarpus ekmanii*. Its fauna includes parrots, lizards, hummingbirds, the endangered Cuban solenodon, hutias, and snails. Over 900 plant species have been recorded, along with 45 reptiles, 21 amphibians, and 10 mammals. BirdLife International has designated it an Important Bird Area, supporting species such as northern bobwhites, Cuban kites, bee hummingbirds, and Cuban trogons.
Historically, the area saw little human use; only one pre-Columbian archaeological site exists, at Aguas Verdes on the coast. During the 18th and 19th centuries, some peripheral spots served as refuges for maroons. The park’s planning began in the 1960s with the Jaguani and Cupeyal del Norte nature reserves, followed in the 1980s by the Ojito del Agua Refuge, linked to the last sighting of the Cuban ivory-billed woodpecker. In 1996, these protected areas merged into a national park named after Humboldt. Along with Cuchillas del Toa, it was declared a UNESCO World Heritage Site in 2001, noted for its unique ecosystem and some of the highest endemism rates in the archipelago.

Lore & Background
The park's rivers are among the largest in the insular Caribbean, and it is considered the most humid place in Cuba, fostering high biological diversity. Its geology is complex, featuring karst landscapes from Cretaceous oceanic crust and ultrabasic serpentine soils and peridotites. The area served as a Pleistocene refugium, maintaining a stable climate through glaciations, which allowed for remarkable endemism. The toxic ultrabasic rocks drove rapid speciation. The park protects 16 of Cuba's 28 endemic plant species, including Dracaena cubensis and Podocarpus ekmanii, and hosts fauna such as the endangered Cuban solenodon, hutia, and various birds.
Reader's Guide
Alejandro de Humboldt National Park is significant as a UNESCO World Heritage Site recognized for its size, altitude range, complex lithology, landform diversity, and wealth of endemic flora and fauna. It is one of the most important biosphere reserves in the Caribbean basin. The park's ultrabasic geology and role as a Pleistocene refugium have produced exceptionally high rates of endemism, with over 900 plant species, 45 reptile species, 21 amphibian species, and 10 mammal species recorded. It also serves as an Important Bird Area, supporting numerous bird species including the Cuban solenodon and various parrots. Historically, the area saw little human use, with only one pre-Columbian archaeological site known, and peripheral areas used as refuges by maroons in the 18th and 19th centuries. The park was established in 1996 by uniting earlier reserves from the 1960s and 1980s, including the Ojito del Agua Refuge associated with the last sighting of the Cuban ivory-billed woodpecker.
