More than 80% of Guyana is still covered by forests, ranging from dry evergreen and seasonal forests to montane and lowland evergreen rain forests. These forests are home to more than a thousand species of trees. Guyana’s tropical climate, unique geology, and relatively pristine ecosystems support extensive areas of species-rich rain forests and natural habitats with high levels of endemism. Approximately eight thousand species of plants occur in Guyana, half of which are found nowhere else.
Guyana is one of the countries with the highest biodiversity in the world. Guyana, with 1,168 vertebrate species, 1,600 bird species, boasts one of the richest mammalian fauna assemblages of any comparably sized area in the world. The Guiana Shield region is little known and extremely rich biologically. Unlike other areas of South America, over 70% of the natural habitat remains pristine. The rich natural history of British Guiana was described by early explorers Sir Walter Raleigh and Charles Waterton and later by naturalists Sir David Attenborough and Gerald Durrell.
The fauna of Guyana comprises all the animal species inhabiting the country of Guyana, which is part of the neotropical realm. Guyana has many endemic species and one of the highest biodiversity rates in the world as a result of the majority of the country being part of the Amazon rainforest, and as a result a large amount of the species being types of frogs or spiders. Guyana’s has three distinct main biomes are tropical rainforests, wetlands, and savannas, and each biome has unique fauna associated.
There are 47,677 unique species classified as part of Guyana, of which 17,291 (36.27%) are classified as an endangered species. As part of conservation efforts, parts of Guyana have been designated as national parks.
