Songhor Lagoon
The Songor Lagoon is located at 05°45'N 000°30'E on the eastern coast of Ghana, West Africa. The site covers an area of 28,740 hectares, and it is located just outside the major town of Ada and to the west of the Volta River estuary. It was designated as Ramsar wetland site of international importance number 566 on June 22, 1988. In 2011, UNESCO approved the Songor Biosphere Reserve as part of the World Network of Biosphere Reserves. Among several other important functions, it acts as habitat and/or breeding ground for several notable species. Physical features The site itself is a closed lagoon that is continually refilled by seepage, runoff, creeks, and streams. It is characterized by high salinity levels and surrounded by mudflats that are inundated for most of the year. The soil is a tropical gray earth type with an unconsolidated sand, clay, and gravel composition. Up to a depth of 80 cm, visibility allows for a clear view of the bottom of the lagoon.

Ramsar Convention
The Ramsar Convention on Wetlands of International Importance Especially as Waterfowl Habitat is an international treaty for the conservation and sustainable use of Ramsar sites (wetlands). It is also known as the Convention on Wetlands. It is named after the city of Ramsar in Iran, where the convention was signed in 1971. Every three years, representatives of the contracting parties meet as the Conference of the Contracting Parties (COP), the policy-making organ of the convention which adopts decisions (resolutions and recommendations) to administer the work of the convention and improve the way in which the parties are able to implement its objectives. COP12 was held in Punta del Este, Uruguay, in 2015. COP13 was held in Dubai, United Arab Emirates, in October 2018. List of wetlands of international importance The list of wetlands of international importance included 2,331 Ramsar sites in May 2018 covering over . The countries with most sites are the United Kingdo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Azadirachta Indica
''Azadirachta indica'', commonly known as neem, nimtree or Indian lilac, is a tree in the mahogany family Meliaceae. It is one of two species in the genus ''Azadirachta'', and is native to the Indian subcontinent and most of the countries in Africa. It is typically grown in tropical and semi-tropical regions. Neem trees also grow on islands in southern Iran. Its fruits and seeds are the source of neem oil. Description Neem is a fast-growing tree that can reach a height of , and rarely . It is deciduous, shedding many of its leaves during the dry winter months. The branches are wide and spreading. The fairly dense crown is roundish and may reach a diameter of . The neem tree is similar in appearance to its relative, the chinaberry (''Melia azedarach''). The opposite, pinnate leaves are long, with 20 to 30 medium to dark green leaflets about long. The terminal leaflet often is missing. The Petiole (botany), petioles are short. White and fragrant flowers are arranged in more-or- ...

Keta
Keta is a coastal town in the Volta Region of Ghana. It is the capital of the Keta Municipal District. Keta was an important trading post between the 14th and the late 20th centuries. The town attracted the interest of the Danish, because they felt they could establish a base here without interference from rival European nations. Their first initiative was to place a factory at Keta to sell alcohol. In 1792, a war between Anloga and Keta broke out. The original people then migrated across the lagoon to Klikor to establish the Somey State with Agbozume as its capital. Keta was then repopulated with people from other areas of the surrounding communities. Faced with the threat of war between Peki and an alliance of the Ashanti and the Akwamu, the North German Missionary Society (also known as the Bremen Missionaries) moved the focus of their activities from Peki to Keta. Their missionaries, Dauble and Plessing, landed at nearby Dzelukofe on September 2, 1853. Historically Keta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tringa
''Tringa'' is a genus of waders, containing the shanks and tattlers. The genus name ''Tringa'' is the New Latin name given to the green sandpiper by the Italian naturalist Ulisse Aldrovandi in 1599. They are mainly freshwater birds, often with brightly coloured legs as reflected in the English names of six species, as well as the specific names of two of these and the green sandpiper. They are typically associated with northern hemisphere temperate regions for breeding. Some of this group—notably the green sandpiper—nest in trees, using the old nests of other birds, usually thrushes. The willet and the tattlers have been found to belong in ''Tringa''; these genus changes were formally adopted by the American Ornithologists' Union in 2006. The present genus in the old, more limited sense was even further subdivided into ''Tringa'' proper and ''Totanus'', either as subgenera or as full genera. The available DNA sequence data suggests however that neither of these is monophyl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sternidae
Terns are seabirds in the family Laridae that have a worldwide distribution and are normally found near the sea, rivers, or wetlands. Terns are treated as a subgroup of the family Laridae which includes gulls and skimmers and consists of eleven genera. They are slender, lightly built birds with long, forked tails, narrow wings, long bills, and relatively short legs. Most species are pale grey above and white below, with a contrasting black cap to the head, but the marsh terns, the Inca tern, and some noddies have dark plumage for at least part of the year. The sexes are identical in appearance, but young birds are readily distinguishable from adults. Terns have a non-breeding plumage, which usually involves a white forehead and much-reduced black cap. Terns are long-lived birds and are relatively free from natural predators and parasites; most species are declining in numbers due directly or indirectly to human activities, including habitat loss, pollution, disturbance, an ...

Recurvirostra
The four species of avocets are a genus, ''Recurvirostra'', of waders in the same avian family as the stilts. The genus name comes from Latin , 'curved backwards' and , 'bill'. The common name is thought to derive from the Italian ( Ferrarese) word . Francis Willughby in 1678 noted it as the "Avosetta of the Italians". Biology Avocets have long legs and they sweep their long, thin, upcurved bills from side to side when feeding in the brackish or saline wetlands they prefer. Their plumage is pied, sometimes also with some red. Members of this genus have webbed feet and readily swim. Their diet consists of aquatic insects and other small creatures. They nest on the ground in loose colonies. In estuarine settings, they may feed on exposed bay muds or mudflats. The pied avocet is the emblem of the Royal Society for the Protection of Birds. Taxonomy The genus ''Recurvirostra'' was introduced in 1758 by Swedish naturalist Carl Linnaeus in the 10th edition of his to contain a sing ...

Manatee
Manatees (family Trichechidae, genus ''Trichechus'') are large, fully aquatic, mostly herbivorous marine mammals sometimes known as sea cows. There are three accepted living species of Trichechidae, representing three of the four living species in the order Sirenia: the Amazonian manatee (''Trichechus inunguis''), the West Indian manatee (''Trichechus manatus''), and the West African manatee (''Trichechus senegalensis''). They measure up to long, weigh as much as , and have paddle-like tails. Manatees are herbivores and eat over 60 different freshwater and saltwater plants. Manatees inhabit the shallow, marshy coastal areas and rivers of the Caribbean Sea, the Gulf of Mexico, the Amazon basin, and West Africa. The main causes of death for manatees are human-related issues, such as habitat destruction and human objects. Their slow-moving, curious nature has led to violent collisions with propeller-driven boats and ships. Some manatees have been found with over 50 scars on them ...

Olive Ridley Sea Turtle
The olive ridley sea turtle (''Lepidochelys olivacea''), also known commonly as the Pacific ridley sea turtle, is a species of turtle in the family Cheloniidae. The species is the second-smallest and most abundant of all sea turtles found in the world. ''L. olivacea'' is found in warm and tropical waters, primarily in the Pacific and Indian Oceans, but also in the warm waters of the Atlantic Ocean. This turtle and the related Kemp's ridley turtle are best known for their unique synchronised mass nestings called ''arribadas'', where thousands of females come together on the same beach to lay eggs. Taxonomy The olive ridley sea turtle may have been first described as ''Testudo mydas minor'' by Georg Adolf Suckow in 1798. It was later described and named ''Chelonia multiscutata'' by Heinrich Kuhl in 1820. Still later, it was described and named ''Chelonia olivacea'' by Johann Friedrich von Eschscholtz in 1829. The species was placed in the subgenus ''Lepidochelys'' by Leopold Fitz ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Green Sea Turtle
The green sea turtle (''Chelonia mydas''), also known as the green turtle, black (sea) turtle or Pacific green turtle, is a species of large sea turtle of the family Cheloniidae. It is the only species in the genus ''Chelonia''. Its range extends throughout tropical and subtropical seas around the world, with two distinct populations in the Atlantic and Pacific Oceans, but it is also found in the Indian Ocean. The common name refers to the usually green fat found beneath its carapace, not to the color of its carapace, which is olive to black. The dorsoventrally flattened body of ''C. mydas'' is covered by a large, teardrop-shaped carapace; it has a pair of large, paddle-like flippers. It is usually lightly colored, although in the eastern Pacific populations, parts of the carapace can be almost black. Unlike other members of its family, such as the hawksbill sea turtle, ''C. mydas'' is mostly herbivorous. The adults usually inhabit shallow lagoons, feeding mostly on various ...

Leatherback Sea Turtle
The leatherback sea turtle (''Dermochelys coriacea''), sometimes called the lute turtle or leathery turtle or simply the luth, is the largest of all living turtles and the heaviest non-crocodilian reptile, reaching lengths of up to and weights of . It is the only living species in the genus ''Dermochelys'' and family Dermochelyidae. It can easily be differentiated from other modern sea turtles by its lack of a bony shell; instead, its carapace is covered by oily flesh and flexible, leather-like skin, for which it is named. Taxonomy and evolution Taxonomy ''Dermochelys coriacea'' is the only species in genus ''Dermochelys''. The genus, in turn, contains the only extant member of the family Dermochelyidae. Domenico Agostino Vandelli named the species first in 1761 as ''Testudo coriacea'' after an animal captured at Ostia and donated to the University of Padua by Pope Clement XIII. In 1816, French zoologist Henri Blainville coined the term ''Dermochelys''. The leatherback was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mangrove Restoration
Mangrove restoration is the regeneration of mangrove forest ecosystems in areas where they have previously existed. The practice of mangrove restoration is grounded in the discipline of restoration ecology, which aims to “ ssistthe recovery of resilience and adaptive capacity of ecosystems that have been degraded, damaged, or destroyed”. Since environmental impacts are an ongoing threat, to successfully restore an ecosystem implies not merely to recreate its former condition, but to strengthen its capacity to adapt to change over time. Mangrove forests are most likely to thrive in the upper half of the intertidal zone. If planted below the mean tide level, or subject to too great a sea level rise, they may fail to thrive. Success will also depend on the species chosen and their suitability to conditions. Environmental context Mangrove forests, along with the animal species they shelter, represent globally significant sources of biodiversity and provide humanity with valuabl ...

IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
