Guianan Forests & Savanna (NT21) | One Earth

Guianan Forests & Savanna bioregion

The bioregion’s land area is provided in units of 1,000 hectares. The protection goal is the combined Global Safety Net (GSN1) areas for the component ecoregions. The protection level indicates the percentage of the GSN goal that is currently protected on a scale of 0-10. N/A means data is not available at this time.

The Guianan bioregion, located in the Southern America (Neotropical) realm, extends from the eastern edge of the Guiana shield, at the border of Venezuela and Colombia, to the Atlantic coast. It contains the Guiana Highlands with its rocky plateaus that are the source for many waterfalls including the world’s highest, Angel Falls. The bioregion is covered in dense tropical forest and also includes the Guinan savannas, with nine terrestrial ecoregions – Guianan Freshwater Swamp Forests (463), Guianan Highlands Moist Forests (464), Guianan Lowland Moist Forests (465), Guianan Piedmont Moist Forests (466), Orinoco Delta Swamp Forests (488), Pantepui Forests and Shrublands (490), Trinidad and Tobago Moist Forest (510), Trinidad and Tobago Dry Forests (548), Guianan Savanna (570) – as well as significant stands of Amazon-Orinoco-Southern Caribbean Mangroves (611) and Orinoco Wetlands (583). This bioregion is considered one of the most biodiverse in the world with 3000 vertebrate species and over 13,000 plant species, two-fifths of which are endemic. The total area of this bioregion is approximately 106 million hectares, not including adjacent marine areas.

The Guianan Forests & Savanna bioregion bioregion is part of the Upper South America subrealm and is made up of 11 ecoregions: (1) Guianan Savanna (2) Pantepui Forests and Shrublands (3) Guianan Highlands Moist Forests (4) Guianan Piedmont Moist Forests (5) Orinoco Delta Swamp Forests (6) Orinoco Wetlands (7) Trinidad and Tobago Dry Forests (8) Trinidad and Tobago Moist Forest (9) Guianan Lowland Moist Forests (10) Guianan Freshwater Swamp Forests (11) Amazon-Orinoco-Southern Caribbean Mangroves.
