Marais Audomarois
The Marais Audomarois is a wetland biosphere reserve in the north of France. The renowned Ramsar site covers some 22 300 hectares, including the city Saint-Omer. Geography The Audomarois landscape owes its richness to its particular geography. It is located on an intersection between three natural regions: the coastal plain, the Flanders intérieure and the Artois hills. These multifaceted landscapes are host to a wide variety of flora and fauna. The main natural habitats are reedbeds, tall herbs, peaty woods, meadows, ditches and rivers. The many species of flora include aquatic vegetation such as flowering rush (''Butomus umbellatus''), greater spearwort ('' Ranunculus lingua'') and marsh fern (''Thelypteris palustris''), as well as underwater and floating vegetation. These habitat types enable many species of birds to breed, feed and rest. There are also a number of endangered species in the region, including cowbane (''Cicuta virosa''), river water-dropwort (''Oenanthe f ...

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] |
Stratiotes Aloides
''Stratiotes aloides'', commonly known as water soldiers or water pineapple, is a submerged aquatic plant native to Europe and northwestern Asia. In Britain it was once common in East Anglia and still is in many places, particularly wet ditches and healthy ponds. It is the only species in the genus Stratiotes. Invasive species ''Stratiotes aloides'' has been found in the Trent River (Ontario), Trent River in eastern Ontario, Canada. Description ''Stratiotes aloides'' has a Rosette (botany), rosette of serrated leaves, lanceolate, up to 30 cm long in tufts. White flowers are up to 45 mm across with many stamens in the male plants are produced in the summer.Parnell, J. and Curtis, T. 2012.'' Webb's An Irish Flora'' Cork University press. Ecological aspects In the summer this plant floats on the water surface with the leaves just above the surface. In the autumn they become covered with a slimy secretion (calcium carbonate) and the whole plant sinks to the bottom to ris ...

Biosphere Reserves Of France
The biosphere (from Greek βίος ''bíos'' "life" and σφαῖρα ''sphaira'' "sphere"), also known as the ecosphere (from Greek οἶκος ''oîkos'' "environment" and σφαῖρα), is the worldwide sum of all ecosystems. It can also be termed the zone of life on Earth. The biosphere (which is technically a spherical shell) is virtually a closed system with regard to matter, with minimal inputs and outputs. With regard to energy, it is an open system, with photosynthesis capturing solar energy at a rate of around 130 terawatts per year. However it is a self-regulating system close to energetic equilibrium."Biosphere" in ''The Columbia Encyclopedia'', 6th ed. (2004) Columbia University Press.

Amiens
Amiens (English: or ; ; pcd, Anmien, or ) is a city and commune in northern France, located north of Paris and south-west of Lille. It is the capital of the Somme department in the region of Hauts-de-France. In 2021, the population of Amiens was 135,429. A central landmark of the city is Amiens Cathedral, the largest Gothic cathedral in France. Amiens also has one of the largest university hospitals in France, with a capacity of 1,200 beds.

The town was fought over during both World Wars, suffering significant damage, and was repeatedly occupied by both sides. The 1918 Battle of Amiens was the opening phase of the Hundred Days Offensive which directly led to the Armistice with Germany. The Royal Air Force heavily bombed the town during the Second World War. In the aftermath, the city was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Floating Islands
A floating island is a mass of floating aquatic plants, mud, and peat ranging in thickness from several centimeters to a few meters. Floating islands are a common natural phenomenon that are found in many parts of the world. They exist less commonly as an artificial phenomenon. Floating islands are generally found on marshlands, lakes, and similar wetland locations, and can be many hectares in size. Natural occurrences Sometimes referred to as ''tussocks'', ''floatons'', or ''suds'', natural floating islands are composed of vegetation growing on a buoyant mat of plant roots or other organic detritus. In aquatic regions of Northwestern Europe several hundred hectares or thousand acres of floating meadows (German ''Schwingrasen'', Dutch ''trilveen'') have been preserved, which are partly used as agricultural land, partly as nature reserves. They typically occur when growths of cattails, bulrush, sedge, and reeds extend outward from the shoreline of a wetland area. As the wate ...

Natura 2000
Natura 2000 is a network of nature protection areas in the territory of the European Union. It is made up of Special Areas of Conservation and Special Protection Areas designated under the Habitats Directive and the Birds Directive, respectively. The network includes both terrestrial and Marine Protected Areas. History In May 1992, the governments of the European Communities adopted legislation designed to protect the most seriously threatened habitats and species across Europe. The Habitats Directive complements the Birds Directive adopted earlier in 1979 and together they make up the Natura 2000 network of protected areas. The Birds Directive requires the establishment of Special Protection Areas for birds. The Habitats Directive similarly requires Sites of Community Importance which upon the agreement of the European Commission become Special Areas of Conservation to be designated for species other than birds, and for habitat types (e.g. particular types of forest, grassland ...

Acrocephalus Paludicola
The aquatic warbler (''Acrocephalus paludicola'') is an Old World warbler in the genus '' Acrocephalus''. It breeds in temperate eastern Europe and western Asia, with an estimated population of 11,000-15,000 pairs. It is migratory, wintering in west Africa. After many years of uncertainty, the wintering grounds of much of the European population were finally discovered in Djoudj National Bird Sanctuary, Senegal, with between 5,000 and 10,000 birds present at this single site. Its south-westerly migration route means that it is regular on passage as far west as Great Britain and Ireland. This small passerine bird is a species found in wet sedge beds with vegetation shorter than . Drainage has meant that this species has declined, and its stronghold is now the Polesie region of eastern Poland and south Belarus, where 70% of the world's population breeds. 3–5 eggs are laid in a nest in low vegetation. This species is highly promiscuous, with most males and females having offspring ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acrocephalus Scirpaceus
The common reed warbler (''Acrocephalus scirpaceus'') is an Old World warbler in the genus '' Acrocephalus''. It breeds across Europe into the temperate western Palaearctic where it is migratory, wintering in sub-Saharan Africa. It is also a resident species over large parts of Africa. Taxonomy The common reed warbler was formally described in 1804 by the French naturalist Johann Hermann under the binomial name ''Turdus scirpaceus''. The type locality is Alsace. The common reed warbler is now one of around 40 species placed in the genus '' Acrocephalus'' that was introduced by Johann Andreas Naumann and his son Johann Friedrich Naumann in 1811. The genus name ''Acrocephalus'' is from Ancient Greek ''akros'', "highest", and ''kephale'', "head". It is possible that the Naumanns thought ''akros'' meant "sharp-pointed". The specific ''scirpaceus'' is from Latin and means "reed". Ten subspecies are recognised: * ''A. s. scirpaceus'' (Hermann, 1804) – breeds in Europe to west Russ ...

Luscinia Svecica
The bluethroat (''Luscinia svecica'') is a small passerine bird that was formerly classed as a member of the thrush family Turdidae, but is now more generally considered to be an Old World flycatcher, Muscicapidae. It, and similar small European species, are often called chats. It is a migratory insectivorous species breeding in wet birch wood or bushy swamp in Europe and across the Palearctic with a foothold in western Alaska. It nests in tussocks or low in dense bushes. It winters in north Africa and the Indian subcontinent. The bluethroat is similar in size to the European robin at 13–14 cm. It is plain brown above except for the distinctive black tail with red side patches. It has a strong white supercilium. Despite the distinctive appearance of the males, recent genetic studies show only limited variation between the forms, and confirm that this is a single species. Moults begins in July after breeding and are completed in 40–45 days, before the birds migrate. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acrocephalus Schoenobaenus
The sedge warbler (''Acrocephalus schoenobaenus'') is an Old World warbler in the genus '' Acrocephalus''. It is a medium-sized warbler with a brown, streaked back and wings and a distinct pale supercilium. Sedge warblers are migratory, crossing the Sahara to get from their European and Asian breeding grounds to spend winter in Africa. The male's song is composed of random chattering phrases and can include mimicry of other species. The sedge warbler is mostly insectivorous. Taxonomy The sedge warbler was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under the binomial name ''Motacilla schoenobaenus''. The species is now placed in the genus '' Acrocephalus'' that was introduced in 1811 by Johann Andreas Naumann and his son Johann Friedrich Naumann. British ornithologists did not distinguish the species from the Eurasian reed warbler until the 18th century. The genus name ''Acrocephalus'' is from Ancient Greek ...

Oenanthe Fluviatilis
''Oenanthe fluviatilis'', the river water-dropwort, is a flowering plant in the carrot family, Apiaceae, which is endemic to north-west Europe. It grows only in clear, unpolluted rivers and is declining throughout its range. Description River water-dropwort is a hairless perennial with hollow, ridged stems up to 1 m long, submerged or floating in rivers, or emergent in marginal swamps and during periods of low flow in summer. The stems creep along the surface of mud, or on the bottom of a river, rooting at the nodes. These extend upwards through the water column, becoming thicker as they ascend, to a diameter of about an inch (2.5 cm), with a central hollow about half that size. Young plants have tubers, which disappear as they mature, leaving just fibrous roots. The lower, underwater leaves are once to twice pinnate, with distinctive cuneate (diamond shaped) segments which are deeply divided into almost linear lobes (especially so in faster-flowing water), with ...
