Imagine a soil so poor and so laden with metals that almost no plant can live in it. Anywhere else in the world that would be a biological desert; in northeastern Cuba it was just the opposite: the starting point of one of the corners with the most unique species on the planet. The extraordinary natural richness of Alejandro de Humboldt National Park sinks its roots, literally, in geology. The Nipe-Sagua-Baracoa massif, at the far northeastern tip of the island, is one of the geologically oldest and most complex regions in Cuba, with outcrops of very peculiar rocks and soils, among them serpentinites and soils rich in metals and poor in nutrients. Paradoxically, that poverty and toxicity of the soil, which make agriculture difficult, were the engine of a unique biological evolution: only the plants capable of adapting to those extreme conditions prospered, giving rise to a highly specialized and endemic flora.
To that geological base were added other factors: a mountainous and rugged relief that created a multitude of microclimates and isolated habitats, abundant rains that feed a lush rainforest, and the island condition, which favors the emergence of native species as the populations remain separated from the continent. The result is a mosaic of ecosystems —rainforest, pine woods, cloud forests, mangroves and coast— concentrated in a relatively small territory.
For millennia, this isolation allowed forms of life to evolve here that exist nowhere else on the planet: the colorful polymitas, minuscule amphibians, singular birds, carnivorous plants and hundreds of exclusive plant species. The area, moreover, suffered relatively little human pressure because of the rugged terrain, which helped preserve this heritage. Understanding the park begins with understanding that its beauty is the fruit of millions of years of evolution on a difficult and singular soil.
The park pays tribute in its name to Alexander von Humboldt, the famous German naturalist, geographer and explorer who, together with the botanist Aimé Bonpland, made in the early 19th century one of the great scientific journeys in history through Spanish America. Humboldt visited Cuba twice (in 1800-1801 and again in 1804) and devoted to the island detailed studies of its geography, its climate, its nature, its economy and its society, including a famous critical essay on slavery.
His observations of Cuban nature, gathered in his monumental work, were so valuable and pioneering that he has been called 'the second discoverer of Cuba'. Humboldt embodied a new way of looking at the natural world: as an interconnected whole, in which climate, geology, vegetation and animal life relate to one another, a vision that anticipated modern ecology.
That the national park with the greatest biodiversity in Cuba bears his name is, therefore, a deeply coherent tribute: it celebrates the man who taught us to observe nature as a living system and who left testimony of the natural splendor of the island. The name thus unites science and conservation, and recalls that protecting places like this is to honor that long tradition of wonder and study of the natural world.
The awareness of the extraordinary natural value of this region of northeastern Cuba led, in the 20th century, to driving its protection. The area was integrated into conservation figures and reserves, recognized as one of the most important biodiversity enclaves in Cuba and the insular Caribbean. The national park today protects a broad territory that ranges from the mountain peaks to the coast, including river basins, rivers, mangroves and bays.
The definitive international recognition came in 2001, when UNESCO inscribed Alejandro de Humboldt National Park on the World Heritage List, valuing it as one of the biologically most diverse sites of any tropical island ecosystem on Earth, with a very high number of endemic species. The designation underscored both the importance of its unique flora and fauna and that of its ecosystems and natural processes.
The protection seeks to conserve this heritage against threats such as mining (the region is rich in nickel and other metals), deforestation or poorly managed tourist pressure. That is why visits are made in a controlled way and always with guides, on delimited trails, to minimize the impact. The park today represents a delicate balance between conserving an irreplaceable natural treasure and the possibility for visitors to get to know it and learn to value it. It is, ultimately, a legacy that Cuba —and the world— has the responsibility to care for.
Although the park protects above all nature, the region of northeastern Cuba also has a long human history. Before the arrival of the Europeans, these mountains and coasts were inhabited by aboriginal peoples —Taíno and, in more remote areas, earlier communities—, who lived from fishing, gathering, hunting and an incipient agriculture, and who left petroglyphs, shell middens and other archaeological vestiges scattered around the Baracoa and Toa river area.
It was precisely here that the colonial history of Cuba began: in 1511, Diego Velázquez founded on this coast the town of Nuestra Señora de la Asunción de Baracoa, the first of the seven Spanish towns on the island, known ever since as the 'first-founded city' of Cuba. Baracoa was even the first capital of the colony, before the center of power moved to Santiago and then to Havana. The extreme difficulty of land communications —the region remained isolated from the rest of Cuba until the construction of the La Farola viaduct, in the 20th century— preserved both its singular culture and its almost intact nature.
That historic isolation explains much of the Humboldt miracle: while in other areas of Cuba sugarcane, coffee and cattle ranching razed the forests, here the rugged terrain and the remoteness kept mass deforestation at bay. The unique cuisine of Baracoa —based on coconut, cacao, plantain and fish— and its peasant traditions are heirs to that history of isolation and adaptation to the environment. Thus, the conservation of the park protects not only species, but also the setting where Cuba's most exuberant nature and the first chapters of its history crossed paths.
