Caribbean shrublands

The Caribbean shrublands is a deserts and xeric shrublands ecoregion located in the Neotropic biogeographic realm, covering Central and South America, the Caribbean, and southern portions of Mexico, spanning approximately 3,118.0 km². Classified under the WWF ecoregion code NT13599, this region represents a distinct ecological community shaped by its unique combination of climate, geography, and evolutionary history.

Climate and Vegetation

This ecoregion experiences arid to hyper-arid with extreme temperature fluctuations and minimal rainfall. The dominant vegetation consists of sparse succulents, drought-adapted shrubs, and ephemeral annuals. These conditions create the foundation for the ecological communities found within the Caribbean shrublands.

Ecological Significance

Desert species exhibit remarkable adaptations to water scarcity, including nocturnal activity patterns, water-storing tissues, and deep root systems. Biological soil crusts play a critical role in nutrient cycling. The Caribbean shrublands contributes to the broader biodiversity patterns of the Neotropic realm.

Conservation

Like many deserts and xeric shrublands ecosystems, the Caribbean shrublands faces threats from overgrazing, groundwater depletion, solar energy development, and off-road vehicles. Conservation efforts in this ecoregion focus on habitat preservation, sustainable land management, and protecting corridors that connect fragmented habitat patches.
