Sierra Leone River
The Sierra Leone River is a river estuary on the Atlantic Ocean in Western Sierra Leone. It is formed by the Bankasoka River and Rokel River and is between 4 and 10 miles wide (6–16 km) and 25 miles (40 km) long. It holds the major ports of Queen Elizabeth II Quay and Pepel. The estuary is also important for shipping. It is the largest natural harbour in the African continent. Several islands, including Tasso Island (the largest), Tombo Island, and the historically important Bunce Island, are located in the estuary. Lungi International Airport The river separates Freetown, Sierra Leone's capital city, which is on the south side of the harbor, from the country's principal airport, Lungi International Airport, which is on the north side of the harbor in an area called the "Bullom Shore." The primary means of transportation from the airport to Freetown are by speed boat or ferry. Hovercraft and helicopter services are no longer running. Ecology The of the Sierra Leone ...

Atlantic Ocean
The Atlantic Ocean is the second largest of the world's five borders of the oceans, oceanic divisions, with an area of about . It covers approximately 17% of Earth#Surface, Earth's surface and about 24% of its water surface area. During the Age of Discovery, it was known for separating the New World of the Americas (North America and South America) from the Old World of Afro-Eurasia (Africa, Asia, and Europe). Through its separation of Afro-Eurasia from the Americas, the Atlantic Ocean has played a central role in the development of human society, globalization, and the histories of many nations. While the Norse colonization of North America, Norse were the first known humans to cross the Atlantic, it was the expedition of Christopher Columbus in 1492 that proved to be the most consequential. Columbus's expedition ushered in an Age of Discovery, age of exploration and colonization of the Americas by European powers, most notably Portuguese Empire, Portugal, Spanish Empire, Sp ...

Mangrove
A mangrove is a shrub or tree that grows mainly in coastal saline water, saline or brackish water. Mangroves grow in an equatorial climate, typically along coastlines and tidal rivers. They have particular adaptations to take in extra oxygen and remove salt, allowing them to tolerate conditions that kill most plants. The term is also used for tropical coastal vegetation consisting of such species. Mangroves are taxonomically diverse due to convergent evolution in several plant families. They occur worldwide in the tropics and subtropics and even some temperate coastal areas, mainly between latitudes 30° N and 30° S, with the greatest mangrove area within 5° of the equator. Mangrove plant families first appeared during the Late Cretaceous to Paleocene epochs and became widely distributed in part due to the plate tectonics, movement of tectonic plates. The oldest known fossils of Nypa fruticans, mangrove palm date to 75 million years ago. Mangroves are salt-tolerant ...

Rivers Of Sierra Leone
A river is a natural stream of fresh water that flows on land or inside Subterranean river, caves towards another body of water at a lower elevation, such as an ocean, lake, or another river. A river may run dry before reaching the end of its course if it runs out of water, or only flow during certain seasons. Rivers are regulated by the water cycle, the processes by which water moves around the Earth. Water first enters rivers through precipitation, whether from rainfall, the Runoff (hydrology), runoff of water down a slope, the melting of glaciers or snow, or seepage from aquifers beneath the surface of the Earth. Rivers flow in channeled watercourses and merge in confluences to form drainage basins, or catchments, areas where surface water eventually flows to a common outlet. Rivers have a great effect on the landscape around them. They may regularly overflow their Bank (geography), banks and flood the surrounding area, spreading nutrients to the surrounding area.

Ramsar List Of Wetlands Of International Importance
Ramsar sites are protected under by the Ramsar Convention, an international treaty for the conservation movement, conservation and sustainable use of wetlands, recognizing the fundamental ecological functions of wetlands and their economic, cultural, scientific, and recreational value. The convention establishes that "wetlands should be selected for the list on account of their international significance in terms of ecology, botany, zoology, limnology or hydrology." Over the years, the Conference of the Contracting Parties has adopted more specific criteria interpreting the convention text. The Ramsar List organizes the Ramsar sites according to the contracting party that designated each to the list. Contracting parties are grouped into six "regions": Africa, Asia, Europe, Latin American and the Caribbean, North America, and Oceania. , 171 states have acceded to the convention and designated 2,531 sites to the list, covering ; one other state has acceded to the convention but has ye ...

Hooded Vulture
The hooded vulture (''Necrosyrtes monachus'') is an Old World vulture in the order Accipitriformes, which also includes eagles, kites, buzzards and hawks. It is the only member of the genus ''Necrosyrtes,'' which is sister to the larger '' Gyps'' genus, both of which are a part of the Aegypiinae subfamily of Old World vultures. It is native to sub-Saharan Africa, where it has a widespread distribution with populations in southern, East and West Africa. It is a scruffy-looking, small vulture with dark brown plumage, a long thin bill, bare crown, face and fore-neck, and a downy nape and hind-neck. Its face is usually a light red colour.

Curlew Sandpiper
The curlew sandpiper (''Calidris ferruginea'') is a small wader that breeds on the tundra of Arctic Siberia. It is strongly bird migration, migratory, wintering mainly in Africa, but also in south and southeast Asia and in Australia and New Zealand. It is a Vagrancy (biology), vagrant to North America. Taxonomy The curlew sandpiper was species description, formally described in 1763 by the Danish author Erik Pontoppidan under the binomial name ''Tringa ferrugineus''. It is now placed with 23 other sandpipers in the genus ''Calidris'' that was introduced in 1804 by the German naturalist Blasius Merrem. The genus name is from Ancient Greek ''kalidris'' or ''skalidris'', a term used by Aristotle for some grey-coloured waterside birds. The specific ''ferruginea'' is from Latin ''ferrugo, ferruginis'', "iron rust" referring to its colour in breeding plumage. The curlew sandpiper is treated as monotypic: no subspecies are recognised. Within the genus ''Calidris'' the curlew sandpiper i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Eurasian Oystercatcher
The Eurasian oystercatcher (''Haematopus ostralegus'') also known as the common pied oystercatcher, or (in Europe) just oystercatcher, is a wader in the oystercatcher bird family Haematopodidae. It has striking black and white plumage, a long straight orange-red bill, red eyes and relatively short dull pink legs. The sexes are similar in appearance but the bill of the female is longer than that of the male. It is the most widespread of the oystercatchers, with four subspecies breeding in western Europe, central Eurosiberia, Kamchatka, China, and the western coast of Korea. No other oystercatcher occurs within this area. Taxonomy The Eurasian oystercatcher was listed by Swedish naturalist Carl Linnaeus in 1758 in the 10th edition of his ''Systema Naturae'' under the binomial name ''Haemotopus ostralegus''. The genus name ''Haematopus'' combines the Ancient Greek ''haima'' αἷμα meaning "blood" and ''pous'' πούς meaning "foot". The specific epithet ''ostralegus'' combi ...

Important Bird Area
An Important Bird and Biodiversity Area (IBA) is an area identified using an internationally agreed set of criteria as being globally important for the conservation of bird populations. IBA was developed and sites are identified by BirdLife International. There are over 13,000 IBAs worldwide. These sites are small enough to be entirely conserved and differ in their character, habitat or ornithological importance from the surrounding habitat. In the United States the program is administered by the National Audubon Society. Often IBAs form part of a country's existing protected area network, and so are protected under national legislation. Legal recognition and protection of IBAs that are not within existing protected areas varies within different countries. Some countries have a National IBA Conservation Strategy, whereas in others protection is completely lacking.

Lungi International Airport
Freetown International Airport (officially), formerly known as Lungi International Airport, is an international airport situated in the coastal town of Lungi, Sierra Leone. It is the sole international airport in Sierra Leone. The Sierra Leone River separates the airport from Freetown, the capital city. History Until 1949, an airstrip at Waterloo served the city of Freetown. Because of subsidence of the runway and the proximity of the hills, the Government decided in 1947 to abandon Waterloo and make Lungi, a British Royal Air Force base, the airport for Freetown. Waterloo airfield was closed in June 1949. The senior architect of the Public Works Department, Robin Halliday Macartney, supplied a draft plan for the terminal building, which then became the responsibility of the airport engineer A. E. Pugh. The plans had to be altered considerably to comply with new medical regulations and work did not start before 1953. The control tower had been built in 1952. The new terminal ...
