Costa Rican seasonal moist forests

The Costa Rican seasonal 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 10,653 km². Classified under the WWF ecoregion code NT0119, 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 Costa Rican seasonal 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 Costa Rican seasonal moist forests contributes to the broader biodiversity patterns of the Neotropic realm.

Geographic Distribution

The Costa Rican seasonal moist forests extends across Costa Rica and Nicaragua. This geographic range places it within the Neotropic realm, one of the eight major biogeographic divisions of the world.

Notable Species

The Costa Rican seasonal moist forests supports a range of wildlife, including African bristlegrass (Setaria sphacelata), African senna (Senna didymobotrya), Alexandrian laurel (Calophyllum inophyllum), Annual Knawel (Scleranthus annuus), Antelope Grass (Echinochloa pyramidalis), Asian Wild Raspberry (Rubus ellipticus), Beauty Of The Night (Mirabilis jalapa), Beehive Ginger (Zingiber spectabile), and 42 more species. Among these, 1 species is 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 Costa Rican seasonal 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.
