Yucatán moist forests

The Yucatán moist forests is a tropical and subtropical moist broadleaf forests ecoregion located in the Neotropic biogeographic realm, covering Central and South America, the Caribbean, and southern portions of Mexico, spanning approximately 69,482 km². Classified under the WWF ecoregion code NT0181, this region represents a distinct ecological community shaped by its unique combination of climate, geography, and evolutionary history.

Climate and Vegetation

This ecoregion experiences warm year-round with high annual rainfall, typically exceeding 2,000 mm. The dominant vegetation consists of dense, multi-layered canopy of broadleaf evergreen trees. These conditions create the foundation for the ecological communities found within the Yucatán moist forests.

Ecological Significance

These forests are the most biodiverse terrestrial ecosystems on Earth, hosting an extraordinary density of plant and animal species per unit area. Epiphytes, lianas, and a rich understorey characterise the complex vertical structure. The Yucatán moist forests contributes to the broader biodiversity patterns of the Neotropic realm.

Geographic Distribution

The Yucatán moist forests extends across Guatemala and Mexico. This geographic range places it within the Neotropic realm, one of the eight major biogeographic divisions of the world.

Notable Species

The Yucatán moist forests supports a range of wildlife, including Acultzingo Pigmy Salamander (Thorius dubitus), Adler’s Mountain Salamander (Pseudoeurycea kuautli), Admirable False Brook Salamander (Aquiloeurycea praecellens), Anderson's Salamander (Ambystoma andersoni), Anita's False Brook Salamander (Pseudoeurycea anitae), Aquatic Salamander (Pseudoeurycea aquatica), Aquatic Treefrog (Sarcohyla crassa), Arboreal Flat-footed Salamander (Chiropterotriton arboreus), and 42 more species. Among these, 20 species are classified as threatened on the IUCN Red List, underscoring the conservation importance of this ecoregion.

Conservation

Like many tropical and subtropical moist broadleaf forests ecosystems, the Yucatán moist forests faces threats from deforestation, agricultural expansion, logging, and climate change. Conservation efforts in this ecoregion focus on habitat preservation, sustainable land management, and protecting corridors that connect fragmented habitat patches.
