Cuban moist forests

Cuban moist forests form a vital tropical ecoregion primarily located across central and eastern Cuba. This biome is characterized by high biodiversity and significant levels of endemism, thriving in the island's humid mountainous areas. It represents a key component of the Neotropic realm and faces considerable environmental pressures.

Geography and location

The ecoregion is predominantly found in the major mountain ranges of Cuba, including the Sierra Maestra, the Sierra del Escambray, and the Sierra de los Órganos. It also covers significant areas in the Guantánamo Province and the Nipe-Sagua-Baracoa massif. These forests are often adjacent to other distinct Cuban ecoregions such as the Cuban pine forests and the Cuban dry forests. Key protected areas within this region include Alejandro de Humboldt National Park and Turquino National Park, which encompass some of the most intact forest landscapes.

Climate

The climate is classified as tropical rainforest climate under the Köppen climate classification, specifically Af and Am types. It is influenced by the northeast trade winds and the warm currents of the Caribbean Sea, leading to high annual precipitation that often exceeds 2,000 millimeters. There is minimal temperature variation seasonally, but rainfall patterns can create a slightly drier period from November to April. This consistent humidity is crucial for supporting the dense, multi-layered vegetation structure.

Flora

The flora is distinguished by a high canopy dominated by trees such as Ceiba and West Indian Mahogany. The understory is rich with endemic palms like the Copernicia genus and numerous species of tree ferns. Epiphytes, including many orchid species from the Encyclia and Broughtonia genera, are abundant. This ecoregion is part of the Caribbean Islands biodiversity hotspot and contains significant botanical collections studied at institutions like the National Botanical Garden of Cuba.

Fauna

Faunal endemism is exceptionally high, with iconic species such as the critically endangered Cuban solenodon and the Cuban hutia. The region is a haven for avian diversity, hosting birds like the Cuban trogon, the Cuban tody, and the Cuban parrot. Amphibians are represented by numerous endemic frogs from the genus Eleutherodactylus. Notable invertebrates include the Polymita land snails and the Cuban kite swallowtail butterfly, many of which are subjects of conservation studies by organizations like the World Wildlife Fund.

Conservation status and threats

The conservation status is classified as Critical/Endangered by the World Wildlife Fund due to extensive historical habitat loss. Major threats include agricultural expansion, particularly for crops like coffee and citrus, and logging for valuable hardwoods. Mining operations, especially for nickel in areas like Moa, also pose significant risks. Conservation efforts are centered in protected areas such as Cuchillas del Toa Biosphere Reserve and Gran Piedra, though enforcement remains a challenge. International projects, sometimes involving the United Nations Development Programme, aim to bolster protection for this globally significant biome.
