São Tomé, Príncipe, And Annobón Forests
The São Tomé, Príncipe, and Annobón forests, also known as the São Tomé, Príncipe, and Annobón moist lowland forests, is a tropical moist broadleaf forest ecoregion that covers the islands of São Tomé and Príncipe, which form the island nation of São Tomé and Príncipe, as well as the island of Annobón, which is part of Equatorial Guinea. Setting The three islands are volcanic, part of the Cameroon Line of volcanoes that extends from Annobón in the southwest, through the islands of São Tomé, Príncipe, and Bioko, and onto the mainland as Mount Cameroon and the volcanoes of the Cameroon Highlands. Príncipe is the northernmost island, and lies closest to the African mainland, with an area of 128 km2. São Tomé is the largest of the islands, approximately 836 km2, and lies southwest of Príncipe. Annobón is the southernmost island and lies furthest from the African coast, with an area of 17 km2. The islands are mountainous, with the highest pea ...

Gulf Of Guinea
The Gulf of Guinea is the northeasternmost part of the tropical Atlantic Ocean from Cape Lopez in Gabon, north and west to Cape Palmas in Liberia. The intersection of the Equator and Prime Meridian (zero degrees latitude and longitude) is in the gulf. Among the many rivers that drain into the Gulf of Guinea are the Niger and the Volta. The coastline on the gulf includes the Bight of Benin and the Bight of Bonny. Name The origin of the name Guinea is thought to be an area in the region, although the specifics are disputed. Bovill (1995) gives a thorough description: The name " Guinea" was also applied to south coast of West Africa, north of the Gulf of Guinea, which became known as "Upper Guinea", and the west coast of Southern Africa, to the east, which became known as "Lower Guinea". The name "Guinea" is still attached to the names of three countries in Africa: Guinea, Guinea-Bissau, and Equatorial Guinea, as well as New Guinea in Melanesia. Geography The main river ...

São Tomé Ibis
The São Tomé ibis (''Bostrychia bocagei''), also known as the dwarf olive ibis or the dwarf ibis, is endemism, endemic to São Tomé Island, São Tomé off the western coast of Central Africa and exists inside the Gulf of Guinea. Discovered in the 1800s by Francisco Newton, it was once thought to be a subspecies of the larger olive ibis, but is now classified as a distinct species. ''Bostrychia bocagei'' is a critically endangered ibis that measures approximately 2 ft in height. Living with 19 other species of endemic birds on the island, the dwarf ibis is one of 10 that are threatened with extinction. ''B. bocagei'' prefers the southern forests almost exclusively, living there in nests that are high up in the trees to avoid predators. Aside from predation, other common threats to the species include overhunting and habitat loss as a result of overexploitation of resources by the people of São Tomé. Although no specific conservation reforms have been enacted to help ''B. bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Forest Of São Tomé Island
A forest is an area of land dominated by trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a canopy cover of more than 10 percent, or trees able to reach these thresholds ''in situ''. It does not include land that is predominantly under agricultural or urban use." Using this definition, '' Global Forest Resources Assessment 2020'' (FRA 2020) found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the predominant terrestrial ecosystem of Earth, and are found around the globe. More than half of the world's forests are found in only five countries (Brazil, Canada, China, Russia, and the United States). The largest share of forests (45 percent) are in th ...

Syzygium Guineense
''Syzygium guineense'' ( bm, Kokisa) is a leafy forest tree of the family Myrtaceae, found in many parts of Africa both wild and domesticated. Both its fruits and leaves are edible; the pulp and the fruit skin are sucked and the seed discarded. It is sometimes called "waterberry", but this may also refer to other species of ''Syzygium''. ''Syzygium guineense'' is a highly variable species, leading to debate concerning its taxonomy, including its subspecies. Frank White lists four subspecies: ''afromontanum'', ''barotsense'', ''guineense'', and ''huillense'', the last of which is a suffrutex. However, many other subspecies and varieties have been proposed. Its height is usually between 10 and 15 meters, but some specimens have been found as tall as 25 meters. The trunk is broad and fluted and the crown rounded and heavy, with a bark that is smooth when young, but becomes rough and black with age. The branches are dropping, the stems are thick and angular. The young leaves are p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Afromontane
The Afromontane regions are subregions of the Afrotropical realm, one of the Earth's eight biogeographic realms, covering the plant and animal species found in the mountains of Africa and the southern Arabian Peninsula. The Afromontane regions of Africa are discontinuous, separated from each other by lower-lying areas, and are sometimes referred to as the Afromontane archipelago, as their distribution is analogous to a series of sky islands. Geography Afromontane communities occur above elevation near the equator, and as low as elevation in the Knysna-Amatole montane forests of South Africa. Afromontane forests are generally cooler and more humid than the surrounding lowlands. The Afromontane archipelago mostly follows the East African Rift from the Red Sea to Zimbabwe, with the largest areas in the Ethiopian Highlands, the Albertine Rift Mountains of Uganda, Rwanda, Burundi, Democratic Republic of the Congo, and Tanzania, and the Eastern Arc highlands of Kenya and Tanzania. ...
