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.
In February 2004, the Government of Guyana issued a title to more than 1 million acres of land in the Konashen Indigenous District declaring this land as the Konashen Community-Owned Conservation Area (COCA), to be managed by the Wai Wai. In doing so Guyana created the world's largest Community-Owned Conservation Area.[20]
This important event followed a request made by the Wai Wai community to the government of Guyana and Conservation International Guyana (CIG) for assistance in developing a sustainable plan for their lands in Konashen. The three parties signed a Memorandum of Cooperation which outlines a plan for sustainable use of the Konashen COCA’s biological resources, identifies threats to the area’s biodiversity, and helps develop projects to increase awareness of the COCA as well as generate the income necessary to maintain its protected status.
The Konashen Indigenous District of Southern Guyana houses the headwaters of the Essequibo River, Guyana’s principal water source, and drains the Kassikaityu, Kamoa, Sipu and Chodikar rivers. Southern Guyana is host to some of the most pristine expanses of evergreen forests in the northern part of South America. Most of the forests found here are tall, evergreen hill-land and lower montane forests, with large expanses of flooded forest along major rivers. Thanks to the very low human population density of the area, most of these forests are still intact. The Smithsonian Institution has identified nearly 2,700 species of plants from this region, representing 239 distinct families, and there are certainly additional species still to be recorded.
Such incredible diversity of plants supports even more impressive diversity of animal life, recently documented by a biological survey organised by Conservation International. The clean, unpolluted waters of the Essequibo watershed support a remarkable diversity of fish and aquatic invertebrates, and are home to giant river otters, capybaras, and several species of caimans.
On land, large mammals, such as jaguars, tapirs, bush dogs, giant anteaters, and saki monkeys are still common. Over 400 species of birds have been reported from the region, and the reptile and amphibian faunas are similarly rich. The Konashen COCA forests are also home to countless species of insects, arachnids, and other invertebrates, many of which are still undiscovered and unnamed.
The Konashen COCA is relatively unique in that it contains a high level of biological diversity and richness that remains in nearly pristine condition; such places have become rare on earth. This fact has given rise to various non-exploitative, environmentally sustainable industries such as ecotourism, successfully capitalizing on the biological wealth of the Konashen COCA with comparatively little enduring impact.
[edit] World Heritage Site status
Many countries interested in the conservation and protection of natural and cultural heritage sites of the world accede to the Convention Concerning the Protection of the World Cultural and Natural Heritage that was adopted by UNESCO in 1972. Guyana signed the treaty in 1977, the first Caribbean State Party to do so. In the mid-1990s, Guyana seriously began the process of selecting sites for World Heritage nomination, and three sites were considered: Kaieteur National Park, Shell Beach and Historic Georgetown. By 1997, work on Kaieteur National Park was started, and in 1998 work on Historic Georgetown was begun. To date, however, Guyana has not made a successful nomination.
Guyana submitted the Kaieteur National Park, including the Kaieteur Falls, to UNESCO as its first World Heritage Site nomination. The proposed area and surrounds have some of Guyana's most diversified life zones with one of the highest levels of endemic species found anywhere in South America. The Kaieteur Falls is the most spectacular feature of the park, falling a distance of 226 metres. The nomination of Kaieteur Park as a World Heritage Site was not successful, primarily because the area was seen by the evaluators as being too small, especially when compared with the Central Suriname Nature Reserve that had just been nominated as a World Heritage Site (2000). The dossier was thus returned to Guyana for revision.
Guyana continues in its bid for a World Heritage Site. Work continues, after a period of hiatus, on the nomination dossier for Historic Georgetown. A Tentative List indicating an intention to nominate Historic Georgetown was submitted to UNESCO in December 2004. There is now a small committee put together by the Guyana National Commission for UNESCO to complete the nomination dossier and the management plan for the site. In April 2005, two Dutch experts in conservation spent two weeks in Georgetown supervising architecture staff and students of the University of Guyana in a historic building survey of the selected area. This is part of the data collection for the nomination dossier.
Meanwhile, as a result of the Kaieteur National Park being considered too small, there is a proposal to prepare a nomination for a Cluster Site that will include the Kaieteur National Park, the Iwokrama Forest and the Kanuku Mountains. The Iwokrama Rain Forest, an area rich in biological diversity, has been described by Major General (Retired) Joseph Singh as “a flagship project for conservation.” The Kanuku Mountains area is in a pristine state and is home to more than four hundred species of birds and other animals.
There is much work to be done for the successful nomination of these sites to the World Heritage List. The state, the private sector and the ordinary Guyanese citizens each have a role to play in this process and in the later protection of the sites. Inscription on the UNESCO World Heritage will open Guyana to more serious tourists thereby assisting in its economic development.
Guyana exhibits two of the World Wildlife Fund's Global 200 eco-regions most crucial to the conservation of global biodiversity, Guianan moist forests and Guiana Highlands moist forests and is home to several endemic species including the tropical hardwood Greenheart.
