Dunes Of Texel National Park
''Duinen van Texel'' National Park (''duinen'' = dunes) is a national park located on the North Holland island of Texel in the Netherlands. All dune systems on the western side of the island and the large coastal plains on both the northern and southern points of the island are part of the park. The park covers approximately and attained national park status in 2002. The visitor center is located in the natural history museum . In 1927 botanist Jac. P. Thijsse made an illustrated book about the flora and fauna on the island, and pointed out the major environmental values of the island. This book was one of a series, the book was cheap, and the pictures for the book came free with each Verkade chocolate bar. There are many walking trails which follow either red, yellow, blue or green signs The green routes are not accessible during the bird breeding season. Many bicycle trails cross the park as well. Areas From south to north the park comprises the following areas: *De Hor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Holland
North Holland ( nl, Noord-Holland, ) is a province of the Netherlands in the northwestern part of the country. It is located on the North Sea, north of South Holland and Utrecht, and west of Friesland and Flevoland. In November 2019, it had a population of 2,877,909 and a total area of , of which is water. From the 9th to the 16th century, the area was an integral part of the County of Holland. During this period West Friesland was incorporated. In the 17th and 18th century, the area was part of the province of Holland and commonly known as the Noorderkwartier (English: "Northern Quarter"). In 1840, the province of Holland was split into the two provinces of North Holland and South Holland. In 1855, the Haarlemmermeer was drained and turned into land. The provincial capital is Haarlem (pop. 161,265). The province's largest city and also the largest city in the Netherlands is the Dutch capital Amsterdam, with a population of 862,965 as of November 2019. The King's Commis ...

Amphibious Warfare
Amphibious warfare is a type of offensive military operation that today uses naval ships to project ground and air power onto a hostile or potentially hostile shore at a designated landing beach. Through history the operations were conducted using ship's boats as the primary method of delivering troops to shore. Since the Gallipoli Campaign, specialised watercraft were increasingly designed for landing troops, material and vehicles, including by landing craft and for insertion of commandos, by fast patrol boats, zodiacs (rigid inflatable boats) and from mini-submersibles. The term ''amphibious'' first emerged in the United Kingdom and the United States during the 1930s with introduction of vehicles such as Vickers-Carden-Loyd Light Amphibious Tank or the Landing Vehicle Tracked.The first LVT prototypes were named ''Alligator'' and ''Crocodile'', though neither species is actual amphibian Amphibious warfare includes operations defined by their type, purpose, scale and me ...

Ditch
A ditch is a small to moderate divot created to channel water. A ditch can be used for drainage, to drain water from low-lying areas, alongside roadways or fields, or to channel water from a more distant source for plant irrigation. Ditches are commonly seen around farmland, especially in areas that have required drainage, such as The Fens in eastern England and much of the Netherlands. Roadside ditches may provide a hazard to motorists and cyclists, whose vehicles may crash into them and get damaged, flipped over, or stuck and cause major injury, especially in poor weather conditions and rural areas. Etymology In Anglo-Saxon, the word ''dïc'' already existed and was pronounced "deek" in northern England and "deetch" in the south. The origins of the word lie in digging a trench and forming the upcast soil into a bank alongside it. This practice has meant that the name ''dïc'' was given to either the excavation or the bank, and evolved to both the words "dike"/"dyke" and ...

Common Spoonbill
The Eurasian spoonbill (''Platalea leucorodia''), or common spoonbill, is a wading bird of the ibis and spoonbill family Threskiornithidae. The genus name ''Platalea'' is from Latin and means "broad", referring to the distinctive shape of the bill, and ''leucorodia'' is from Ancient Greek ''leukerodios'' "spoonbill", itself derived from ''leukos'', "white" and ''erodios'' "heron". In England it was traditionally known as the "shovelard", a name later used for the Northern Shoveller. Taxonomy and systematics A study of mitochondrial DNA of the spoonbills found that the Eurasian spoonbill is sister taxon to a clade containing the royal and black-faced spoonbills. The Eurasian spoonbill has three subspecies: * ''P. l. leucorodia'' – Linnaeus, 1758: nominate, occupies all the range except as below. * ''P. l. balsaci'' – Naurois & Roux, 1974: found on the islands off the Banc d'Arguin, Mauritania. * ''P. l. archeri'' – Neumann, 1928: found on the coasts of the Red Sea and ...

Drinking Water
Drinking water is water that is used in drink or food preparation; potable water is water that is safe to be used as drinking water. The amount of drinking water required to maintain good health varies, and depends on physical activity level, age, health-related issues, and environmental conditions. This 2004 article focuses on the USA context and uses data collected from the US military. Recent work showed that the most important driver of water turnover which is closely linked to water requirements is energy expenditure. For those who work in a hot climate, up to a day may be required. Typically in developed countries, tap water meets drinking water quality standards, even though only a small proportion is actually consumed or used in food preparation. Other typical uses for tap water include washing, toilets, and irrigation. Greywater may also be used for toilets or irrigation. Its use for irrigation however may be associated with risks. Water may also be unacceptable due ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake
A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Polder
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Centaurium
''Centaurium'' (centaury) is a genus of 20 species in the gentian family (Gentianaceae), tribe Chironieae, subtribe Chironiinae. The genus was named after the centaur Chiron, famed in Greek mythology for his skill in medicinal herbs. It is distributed across Europe and into Asia. Until 2004, ''Centaurium'' was given a much wider circumscription, comprising about 50 species ranging across Europe, Asia, the Americas, Australasia and the Pacific. However this circumscription was polyphyletic, so in 2004 the genus was split in four, being ''Centaurium'' sensu stricto, '' Zeltnera'', '' Gyrandra'' and ''Schenkia''.

Dactylorhiza Incarnata
''Dactylorhiza incarnata'', the early marsh-orchid, is a perennial, temperate-climate species of orchid generally found growing in wet meadows, and generally on base-rich soils, up to about 2100m asl. The species occurs widely in Europe and Asia from Portugal and Ireland east to Siberia and Xinjiang.Petrova, A.S., Vladimirov, V. & Stoyanov, Y. (2009). ''Dactylorhiza maculata'' subsp. ''transsilvanica'' (Orchidaceae): new for the Bulgarian flora. Phytologia Balcanica 15: 389-392. There are several subspecies and also hybrids, rendering the identification of this species more difficult, but typically, the flowering spike is robust with a hollow stem, 25–60 cm tall, and bearing up to 50 flowers. Plants grow to a height of from 15 to 70 cm. The 4–7 erect yellowish-green leaves are hooded at the tip. The inflorescence is 4–12 cm long, with up to 50 blooms. The labellum appears long and narrow, since its sides are strongly reflexed (folded back). The tip is shallow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parnassia Palustris
''Parnassia palustris'', the marsh grass of Parnassus, northern grass-of-Parnassus, or just grass-of-Parnassus, and bog star, is a flowering plant in the staff-vine family Celastraceae. It is the county flower of Cumberland in England, and appears on its flag. The name comes from ancient Greece: evidently the cattle on Mount Parnassus appreciated the plant; hence it was an "honorary grass". The specific epithet ''palustris'' is Latin for "of the marsh" and indicates its common habitat. It was described by the Greek physician Dioscorides, growing up a mountain in 1st century A.D. Description This perennial plant is not a grass, nor does it look like one, but grows from a short underground stem. It has long stemmed heart-shaped leaves, which are 4-12 in (10–30 cm) long. In the centre of the leaf, is the flowering stem. The stem holds a solitary white flower, blooming between July and October. The flower has 5 stamens around the centre. The flower produces a honey-li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
