Nile Delta Flooded Savanna
The Nile Delta flooded savanna, ecoregion (WWF ID: PA0904) covers both the Nile Delta proper, where the Nile River enters the Mediterranean Sea, as well as the river floodplains of the Nile up-river to the Aswan Dam. Since the Aswan Dam was completed in the 1970s, the Nile on this stretch has not been subject to annual flooding, leading the loss of much of the papyrus sedge ('' Cyperus papyrus'') swamps and other marshes along the river. Location and description At the northern end is the Nile Delta, 175 km long by 260 km wide. There are some lakes and lagoons with marshes near the seacoast; some of the larger are Lake Burullus and Lake Manzala. The topsoil in the delta is up to 21 meters in depth and intensely used for agriculture. The soil quality has been degrading, however, due to the loss of additional sediments from floods, and the use of fertilizers has increased. The western coast of the delta is divided from the sea by a portion of the Mediterranean ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nile River
The Nile, , Bohairic , lg, Kiira , Nobiin: Áman Dawū is a major north-flowing river in northeastern Africa. It flows into the Mediterranean Sea. The Nile is the longest river in Africa and has historically been considered the longest river in the world, though this has been contested by research suggesting that the Amazon River is slightly longer.Amazon Longer Than Nile River, Scientists Say Of the world's major rivers, the Nile is one of the smallest, as measured by annual flow in cubic metres of water.

Grus Grus
The common crane (''Grus grus''), also known as the Eurasian crane, is a bird of the family Gruidae, the cranes. A medium-sized species, it is the only crane commonly found in Europe besides the demoiselle crane (''Grus virgo'') and the Siberian crane (''Leucogeranus leucogeranus''). Along with the sandhill (''Antigone canadensis'') and demoiselle cranes and the brolga (''Antigone rubicunda''), it is one of only four crane species not currently classified as threatened with extinction or conservation dependent on the species level. Despite the species' large numbers, local extinctions and extirpations have taken place in part of its range, and an ongoing reintroduction project is underway in the United Kingdom. Taxonomy The first formal description of the common crane was by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under the binomial name ''Ardea grus''. The current genus ''Grus'' was erected by the French zoologist Mathurin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ciconia Nigra
The black stork (''Ciconia nigra'') is a large bird in the stork family Ciconiidae. It was first described by Carl Linnaeus in the 10th edition of his ''Systema Naturae''. Measuring on average from beak tip to end of tail with a wingspan, the adult black stork has mainly black plumage, with white underparts, long red legs and a long pointed red beak. A widespread but uncommon species, it breeds in scattered locations across Europe (predominantly in Portugal and Spain, and central and eastern parts), and east across the Palearctic to the Pacific Ocean. It is a long-distance migrant, with European populations wintering in tropical Sub-Saharan Africa, and Asian populations in the Indian subcontinent. When migrating between Europe and Africa, it avoids crossing the Mediterranean Sea and detours via the Levant in the east or the Strait of Gibraltar in the west. An isolated, non-migratory, population occurs in Southern Africa. Unlike the closely related white stork, the black sto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ciconia Ciconia
The white stork (''Ciconia ciconia'') is a large bird in the stork family, Ciconiidae. Its plumage is mainly white, with black on the bird's wings. Adults have long red legs and long pointed red beaks, and measure on average from beak tip to end of tail, with a wingspan. The two subspecies, which differ slightly in size, breed in Europe (north to Finland), northwestern Africa, southwestern Asia (east to southern Kazakhstan) and southern Africa. The white stork is a long-distance migrant, wintering in Africa from tropical Sub-Saharan Africa to as far south as South Africa, or on the Indian subcontinent. When migrating between Europe and Africa, it avoids crossing the Mediterranean Sea and detours via the Levant in the east or the Strait of Gibraltar in the west, because the air thermals on which it depends for soaring do not form over water. A carnivore, the white stork eats a wide range of animal prey, including insects, fish, amphibians, reptiles, small mammals and small bird ...

Asian–East African Flyway
The Asian–East African Flyway is a group of well-established routes by which many species of birds migrate annually between mid-Palearctic breeding grounds in Asia and non-breeding sites in eastern and southern Africa. Route The flyway covers an area of and spans 64 countries from South Africa and Madagascar to Eastern Siberia and Alaska. The indirect route, where the birds fly west and then south rather than directly south, avoids the obstacle of the Tibetan Plateau and the Himalayas. The birds usually migrate quickly from the Palaeartic to northeast Africa, reaching Ethiopia or Northern Sudan by late August or September. Some birds then remain in northern Africa for most of the fall before heading south either via Uganda and the Lake Victoria basin or via the Kenyan highlands. In the spring, many birds complete the return journey in six weeks or less, usually taking a route along the coast of East Africa. 331 species use the flyway. Seven sites along the route have over a mil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Typha
''Typha'' is a genus of about 30 species of monocotyledonous flowering plants in the family Typhaceae. These plants have a variety of common names, in British English as bulrush or reedmace, in American English as reed, cattail, or punks, in Australia as cumbungi or bulrush, in Canada as bulrush or cattail, and in New Zealand as raupo. Other taxa of plants may be known as bulrush, including some sedges in ''Scirpus'' and related genera. The genus is largely distributed in the Northern Hemisphere, where it is found in a variety of wetland habitats. The rhizomes are edible. Evidence of preserved starch grains on grinding stones suggests they were already eaten in Europe 30,000 years ago. Description ''Typha'' are aquatic or semi-aquatic, rhizomatous, herbaceous perennial plants. The leaves are glabrous (hairless), linear, alternate and mostly basal on a simple, jointless stem that bears the flowering spikes. The plants are monoecious, with unisexual flowers that develop in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Juncus Maritimus
''Juncus maritimus'', known as the sea rush, is a species of rush that grows on coastlines. It is sometimes considered conspecific with '' Juncus kraussii''. It has a wide distribution across the western Palearctic realm (all of Europe, western Asia and the Maghreb). According to Edward Catich Edward M. Catich (1906–April 14, 1979) was an American Roman Catholic priest, teacher, and calligrapher. He is noted for the fullest development of the thesis that the inscribed Roman square capitals of the Augustan age and afterward owed their ... the ancient Egyptians used ''Juncus maritimus'' as a brush for writing. He describes the process of making one: “the end of which he rushwas cut at a slant and its fibers split by chewing to produce a small chisel-shaped ‘brush‘.”.
