Ecoregions of Guyana

Situated primarily in southeastern Venezuela, the Guianan Highlands moist forests ecoregion is distinct from other ecoregions in Amazonia due to its montane physiography. It hosts vast expanses of tall primary rainforests and open, semi-treeless savannas interrupted by gallery forests.

Located on the northeast coast of South America, the Guianan moist forests are one of the world's most extensive continuous tracts of relatively pristine lowland tropical rainforest. As a result, it holds a wide variety of regional biodiversity with high species endemism and richness levels.

The Guianan savanna is an ecoregion of the Amazon biome in the south of Venezuela, Guyana and Suriname, and the north of Brazil. The savanna covers an area of rolling upland plains on the Guiana Shield between the Amazon and Orinoco basins.

The Orinoco Delta Swamp Forests occur in a diverse matrix of coastal vegetation along the river delta and surrounding regions of northwestern Venezuela and northeastern Guyana. These permanently flooded forests provide habitat to many endangered and endemic species.

The Pantepui forests and shrublands ecoregion in the Guiana Highlands of northern South America hosts an archipelago of more than 50 tabletop mountains with isolated sandstone plateaus and summits atop nearly vertical escarpments called tepuis.
