The Green Venice
The Marais Poitevin () or Poitevin Marsh is a large area of marshland in western France. The name means "Poitou's Marsh" or the "Marsh of the Poitou region". It is a remnant of what was the former . The western zone near the sea (about two-thirds of the area) is called the "dry marsh" (or "dried marsh"). It is used for farming and livestock breeding. The eastern zone, called the "wet marsh", is a maze of islets crisscrossed by picturesque canals, primarily now a tourist destination for boating. It is nicknamed The Green Venice (''la Venise Verte''). Overview With an area of , this is the largest marsh on France's Atlantic coast and the second largest of the country, after the Camargue in Provence. The Marais Poitevin is the most important area of angelica cultivation in France. Extending across three departments (Vendée, Deux-Sèvres, and Charente-Maritime), it is situated west of Niort, north of La Rochelle, and south of Fontenay-le-Comte. In 1979 the Marais Poitevin was dec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Duckweed
Lemnoideae is a subfamily of flowering aquatic plants, known as duckweeds, water lentils, or water lenses. They float on or just beneath the surface of still or slow-moving bodies of fresh water and wetlands. Also known as bayroot, they arose from within the arum or aroid family (Araceae), so often are classified as the subfamily Lemnoideae within the family Araceae. Other classifications, particularly those created prior to the end of the twentieth century, place them as a separate family, Lemnaceae. These plants have a simple structure, lacking an obvious stem or leaves. The greater part of each plant is a small organized "thallus" or "frond A frond is a large, divided leaf. In both common usage and botanical nomenclature, the leaves of ferns are referred to as fronds and some botanists restrict the term to this group. Other botanists allow the term frond to also apply to the lar ..." structure only a few cells thick, often with air pockets (aerenchyma) that allow it ...

Landforms Of Deux-Sèvres
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features. Mountains, hills, plateaux, and plains are the fou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Polders
A polder () is a low-lying tract of land that forms an artificial hydrological entity, enclosed by embankments known as dikes. The three types of polder are: # Land reclaimed from a body of water, such as a lake or the seabed # Flood plains separated from the sea or river by a dike # Marshes separated from the surrounding water by a dike and subsequently drained; these are also known as ''koogs'', especially in Germany The ground level in drained marshes subsides over time. All polders will eventually be below the surrounding water level some or all of the time. Water enters the low-lying polder through infiltration and water pressure of groundwater, or rainfall, or transport of water by rivers and canals. This usually means that the polder has an excess of water, which is pumped out or drained by opening sluices at low tide. Care must be taken not to set the internal water level too low. Polder land made up of peat (former marshland) will sink in relation to its previous l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marshes Of France
A marsh is a wetland that is dominated by Herbaceous plant, herbaceous rather than woody plant species.Keddy, P.A. 2010. Wetland Ecology: Principles and Conservation (2nd edition). Cambridge University Press, Cambridge, UK. 497 p Marshes can often be found at the edges of lakes and streams, where they form a transition between the aquatic and terrestrial ecosystems. They are often dominated by Poaceae, grasses, Juncaceae, rushes or reeds. If woody plants are present they tend to be low-growing shrubs, and the marsh is sometimes called a Carr (landform), carr. This form of vegetation is what differentiates marshes from other types of wetland such as swamps, which are dominated by trees, and mires, which are wetlands that have accumulated deposits of acidic peat. Marshes provide habitats for many kinds of Invertebrate, invertebrates, fish, Amphibian, amphibians, Anseriformes, waterfowl and Aquatic mammal, aquatic mammals.

Marans, Charente-Maritime
Marans () is a commune in the Charente-Maritime department, administrative region of Nouvelle-Aquitaine (before 2015: Poitou-Charentes), southwestern France. It is connected to La Rochelle by the Canal de Marans à La Rochelle. The inhabitants of Marans are known as ''marandais''. Marans is the most northern town in Charente-Maritime, and is sometimes considered to be the "gateway to Aunis", the former province in which it has always belonged since its creation. Marans is a pleasant town on the river ''Sèvre niortaise'' which is a fishing port and a busy tourist trap. Being located north of La Rochelle, it has close relations with the latter to which it has much to owe for its rapid urban and economic growth. History Toponymy The etymology of Marans is believed to be from the Latin, ''mare ante'' which means ''before the sea''.

Saint-Michel-en-l'Herm
Saint-Michel-en-l'Herm () is a commune in the Vendée department in the Pays de la Loire region in western France. One of the most famous local landmarks is the Abbey of Saint-Michel-en-l'Herm. The abbey dates from 682 AD when it was constructed by Benedictine monks from Noirmoutier. In 1569, Protestants attacked it, killing approximately 200 monks. The motives for the attack are still debated, but one theory is that the attackers sought treasure and manuscripts hidden by the Bishop of Luçon.

Before Present
Before Present (BP) years, or "years before present", is a time scale used mainly in archaeology, geology and other scientific disciplines to specify when events occurred relative to the origin of practical radiocarbon dating in the 1950s. Because the "present" time changes, standard practice is to use 1 January 1950 as the commencement date (epoch) of the age scale. The abbreviation "BP" has been interpreted retrospectively as "Before Physics", which refers to the time before nuclear weapons testing artificially altered the proportion of the carbon isotopes in the atmosphere, which scientists must now account for. In a convention that is not always observed, many sources restrict the use of BP dates to those produced with radiocarbon dating; the alternative notation RCYBP stands for the explicit "radio carbon years before present". Usage The BP scale is sometimes used for dates established by means other than radiocarbon dating, such as stratigraphy. This usage differs from t ...

Würm Glaciation
The Würm glaciation or Würm stage (german: Würm-Kaltzeit or ''Würm-Glazial'', colloquially often also ''Würmeiszeit'' or ''Würmzeit''; cf. ice age), usually referred to in the literature as the Würm (often spelled "Wurm"), was the last glacial period in the Alpine region. It is the youngest of the major glaciations of the region that extended beyond the Alps themselves. Like most of the other ice ages of the Pleistocene epoch, it is named after a river, in this case the Würm in Bavaria, a tributary of the Amper. The Würm ice age can be dated to about 115,000 to 11,700 years ago, but sources differ about the dates, depending on whether the long transition phases between the glacials and interglacials (warmer periods) are allocated to one or other of those periods. The average annual temperatures during the Würm ice age in the Alpine Foreland were below −3 °C (today +7 °C). That has been determined from changes in the vegetation (pollen analysis), as well a ...
