Ropotamo Reserve
The Ropotamo ( bg, Ропотамо , from the Ancient Greek word Ροπόταμος ''ropotamos'' meaning "border river") is a river in south-eastern Bulgaria. It takes its source from the Bosna Ridge in the Strandzha Mountains, running for 48.5 km to empty into the Black Sea near Cape Saint Demetrius between Dyuni and Primorsko. The river is most often noted for its 30 m-wide mouth that is home to an abundance of flora species, over 100 of which endangered in the country. The lower section of the river is a protected area since 1940 and forms part of the Ropotamo Reserve. The lower Ropotamo is a popular tourist attraction because of the water lilies and the rock formations above the river, on some of which white-tailed eagles nest. Ropotamo Glacier on Livingston Island in the South Shetland Islands, Antarctica is named after Ropotamo River. Geography Under the name Tserovska River, the Ropotamo originates from the Bosna Ridge in the Strandzha Mountains at some 500 ...

Nymphaea Alba
''Nymphaea alba'', the white waterlily, European white water lily or white nenuphar , is an aquatic flowering plant in the family Nymphaeaceae. It is native to North Africa, temperate Asia, Europe and tropical Asia (Jammu and Kashmir). Description It grows in water that is deep and likes large ponds and lakes. The leaves can be up to in diameter and take up a spread of per plant. The flowers are white and they have many small stamens inside. Taxonomy It was first published and described by Carl Linnaeus in his book 'Species Plantarum', on page 510 in 1753. The red variety (''Nymphaea alba'' f. ''rosea'') is cultivated from lake Fagertärn ("Fair tarn") in the forest of Tiveden, Sweden, where it was discovered in the early 19th century. The discovery led to large-scale exploitation which nearly made it extinct in the wild before it was protected. ''Nymphaea candida'' is sometimes considered a subspecies of ''N. alba'' (''N. alba'' L. subsp. ''candida'' ). Distribution an ...

Hornbeam
Hornbeams are hardwood trees in the flowering plant genus ''Carpinus'' in the birch family Betulaceae. The 30–40 species occur across much of the temperate regions of the Northern Hemisphere. Origin of names The common English name ''hornbeam'' derives from the hardness of the woods (likened to horn) and the Old English ''beam'' "tree" (cognate with Dutch ‘’Boom’’ and German ''Baum''). The American hornbeam is also occasionally known as blue-beech, ironwood, or musclewood, the first from the resemblance of the bark to that of the American beech ''Fagus grandifolia'', the other two from the hardness of the wood and the muscled appearance of the trunk and limbs. The botanical name for the genus, ''Carpinus'', is the original Latin name for the European species, although some etymologists derive it from the Celtic for a yoke. Taxonomy Formerly some taxonomists segregated them with the genera ''Corylus'' ( hazels) and ''Ostrya'' (hop-hornbeams) in a separate family, Coryl ...

Fraxinus
''Fraxinus'' (), common name, commonly called ash, is a genus of flowering plants in the olive and lilac family, Oleaceae. It contains 45–65 species of usually medium to large trees, mostly deciduous, though a number of Subtropics, subtropical species are evergreen. The genus is widespread across much of Europe, Asia, and North America. The leaf, leaves are opposite leaves, opposite (rarely in Whorl (botany), whorls of three), and mostly pinnate, pinnately compound, though simple in a few species. The seeds, popularly known as "keys" or "helicopter seeds", are a type of fruit known as a samara (fruit), samara. Some ''Fraxinus'' species are Dioecy, dioecious, having male and female flowers on separate plants but sex in ash is expressed as a continuum between male and female individuals, dominated by unisexual trees. With age, ash may change their sexual function from predominantly male and hermaphrodite towards femaleness ; if grown as an ornamental and both sexes are present, ...

Riparian Forest
A riparian forest or riparian woodland is a forested or wooded area of land adjacent to a body of water such as a river, stream, pond, lake, marshland, estuary, canal, sink or reservoir. Etymology The term riparian comes from the Latin word ''ripa'', 'river bank'; technically it only refers to areas adjacent to flowing bodies of water such as rivers, streams, sloughs and estuaries. However, the terms ''riparian forest'' and ''riparian zone'' have come to include areas adjacent to non-flowing bodies of water such as ponds, lakes, playas and reservoirs. Characteristics Riparian forests are subject to frequent inundation. Riparian forests help control sediment, reduce the damaging effects of flooding and aid in stabilizing stream banks. Riparian zones are transition zones between an upland terrestrial environment and an aquatic environment. Organisms found in this zone are adapted to periodic flooding. Many not only tolerate it, but require it in order to maintain health an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 .

Spit (landform)
A spit or sandspit is a deposition bar or beach landform off coasts or lake shores. It develops in places where re-entrance occurs, such as at a cove's headlands, by the process of longshore drift by longshore currents. The drift occurs due to waves meeting the beach at an oblique angle, moving sediment down the beach in a zigzag pattern. This is complemented by longshore currents, which further transport sediment through the water alongside the beach. These currents are caused by the same waves that cause the drift. Hydrology and geology Where the direction of the shore inland ''re-enters'', or changes direction, for example at a headland, the longshore current spreads out or dissipates. No longer able to carry the full load, much of the sediment is dropped. This is called deposition. This submerged bar of sediment allows longshore drift or littoral drift to continue to transport sediment in the direction the waves are breaking, forming an above-water spit. Without the co ...
