The Guajira/Barranquilla ecoregion, along the Caribbean Sea in Venezuela and Colombia, is a unique xerophytic area in the neotropics. Proposed as a bird center of endemism, this arid habitat is dominated by thorn scrub and succulents.
Situated primarily in southeastern Venezuela, the Guayanan Highlands ecoregion is distinct from other ecoregions in Amazonia due to its montane physiography. It hosts vast expanses of tall primary rain forest and open, treeless or nearly treeless savannas interrupted by gallery forests.
Located on the northeast coast of South America, the Guianan Moist Forests ecoregion is one of the largest continuous tracts of relatively pristine lowland tropical rain forest in the world. It holds a wide variety of regional biodiversity with high levels of species endemism and richness.
The Guianan savanna is an ecoregion 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.
Los Llanos is a vast tropical grassland plain situated to the east of the Andes in Colombia and Venezuela, in northwestern South America. It is an ecoregion of the flooded grasslands and savannas biome.
The Orinoco Delta Swamp Forests occur in a diverse and porous matrix of coastal vegetation types along the river delta and surrounding regions of northwestern Venezuela and northeastern Guyana. These inundated forests provide habitat to a number of endangered and endemic species.
The Orinoco wetlands ecoregion is located in northeastern Venezuela, within the northern Orinoco Delta. The ecoregion consists of several large and small patches of flooded grasslands, which occur in a habitat mosaic with swamp forests and mangroves.
The Tepui ecogregion, found in the Guiana Highlands of northern South America, is host to an archipelago of isolated sandstone plateaus and dramatic summits, atop nearly vertical escarpments. The tepuis are the remains of the ancient sandstone tableland overlying the Guiana Shield.
The Venezuelan Andes Montane Forests ecoregion is located in the northern arm of the Andes. Surrounded by xeric valleys and páramo, the richness of species and large number of endemic species make this ecoregion one of the most interesting areas of Venezuela in terms of biodiversity.
