Geography of Guyana

Guyana can be divided into five natural regions; a narrow and fertile marshy plain along the Atlantic coast (low coastal plain) where most of the population lives; a white sand belt more inland (hilly sand and clay region), containing most of Guyana's mineral deposits; the dense rain forests (Forested Highland Region) in the middle of the country; the grassy savannah in the southern west; and the larger interior highlands (interior savannah) consisting mostly of mountains that gradually rise to the Brazilian border.

Some of Guyana's highest mountains are Mount Ayanganna (2,042 metres / 6,699 feet), Monte Caburaí (1,465 metres / 4,806 feet) and Mount Roraima (2,835 metres / 9,301 feet — the highest mountain in Guyana) on the Brazil-Guyana-Venezuela tripoint border, part of the Pakaraima range. Mount Roraima and Guyana's table-top mountains (tepuis) are said to have been the inspiration for Sir Arthur Conan Doyle's 1912 novel The Lost World. There are also many steep escarpments and waterfalls, including Kaieteur Falls. Between the Rupununi River and the border with Brazil lies the Rupununi savannah, south of which lie the Kanuku Mountains.

Rupununi SavannahThe four longest rivers are the Essequibo at 1,010 kilometres (628 mi) long, the Courantyne River at 724 kilometres (450 mi), the Berbice at 595 kilometres (370 mi), and the Demerara at 346 kilometres (215 mi). The Courantyne river forms the border with Suriname. At the mouth of the Essequibo are several large islands, including the 145 km (90 mi) wide Shell Beach lies along the northwest coast, which is also a major breeding area for sea turtles (mainly Leatherbacks) and other wildlife.

The local climate is tropical and generally hot and humid, though moderated by northeast trade winds along the coast. There are two rainy seasons, the first from May to mid-August, the second from mid-November to mid-January.

Guyana has one of the largest unspoiled rainforests in South America, some parts of which are almost inaccessible by humans. The rich natural history of Guyana was described by early explorers Sir Walter Raleigh and Charles Waterton and later by naturalists Sir David Attenborough and Gerald Durrell. In 2008, the BBC ran a three-part programme called Lost Land of the Jaguar which highlighted the huge diversity of wildlife, including undiscovered species and rare species such as the giant otter and harpy eagle.
