1. Coastal Plain: This region is a narrow strip of land along the Atlantic coast, characterized by low-lying, fertile land and mangrove swamps. It is the most densely populated area of Guyana, with most of the country's major cities located here.
2. Highland Region: This region covers most of the interior of Guyana and consists of rolling hills and plateaus, interspersed with savannas and forests. It is home to the Guiana Shield, a vast, ancient geological formation.
3. Interior Savanna: This region is located in the south and west of Guyana and consists of vast, open grasslands with scattered trees. It is relatively sparsely populated and is known for its rich biodiversity.
While not considered a separate region, some sources may also include the Essequibo River Basin as a distinct natural area due to its unique ecosystem and ecological importance. It encompasses a significant portion of the Highland Region and contains a diverse range of plant and animal life.
Therefore, while technically three regions are most widely recognized, the Essequibo River Basin may sometimes be mentioned as a separate natural area.
