Lake Engure
Lake Engure is a lake in the western part of Latvia, in the Talsi District. It is the third largest lake in the country after Lake Lubāns and Lake Rāzna. Lake Engure is an ancient sea lagoon, divided from the sea by a 1.5 - 2.5 km wide sand bar with dunes. Its outflow is the artificial Mersraga channel, dug in 1842. It is eutrophic, mostly overgrown with reeds, and contains 16 species of fish. The whole lake and its vicinity have been included in the Lake Engure Nature Park since 1999, although the first natural reserve was established here in 1957. It contains a floating base for ornithologists.BirdLife International (2021Important Bird Areas factsheet: Engure lake.Downloaded from http://www.birdlife.org on 20/09/2021.

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 .

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] |

Lake Lubāns
Lake Lubāns is the largest lake in Latvia (in Latvian: ''Lubāns'', ''Lubānas ezers'' or ''Lubāna ezers''). The lake lies in the center of the Eastern Latvian Lowland. It is a shallow drainage lake, fed by the Rēzekne, Malta, Malmuta and Lisiņa rivers and several smaller brooks, with an outflow via the Aiviekste River into the Daugava River. After damaging spring floods in 1926, several dams and 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 ar ...es were constructed. The elevation of the lake is allowed to fluctuate between approximately 90 and 93 metres above sea level. At an elevation of 90.75 m the lake has an area of 25 km², increasing to about 100 km² at 92.75 m. In that state it is considered to be the biggest lake in Latvia. Other small former lakes ...

Lake Rāzna
Rāzna ( lv, Rāznas ezers, ''Rēznas ezers'') is the second largest water surface and the first in terms of water volume lake in Latvia. It is located in the eastern part of the country on the territory of Rēzekne Municipality, the water area of the lake is divided between Kaunatas, Mākoņkalna and Čornajas parishes. It is located in the central part of the Latgale Upland at an altitude of above sea level. The total area of the lake is , the water surface is . The maximum depth reaches . There are 10 islands on the lake with a total area of , the largest of them is Apshu (9 hectares). In the late 80s - early 90s, the Committee for Environmental Protection drew attention to the deterioration of the ecological state of the lake. In 1999, funds were allocated for a project to create a nature park based on the lake. In 2001, local governments signed a protocol proposing the creation of the Rāzna National Park. In 2004, the official establishment of the Razna Natural Park takes pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dune
A dune is a landform composed of wind- or water-driven sand. It typically takes the form of a mound, ridge, or hill. An area with dunes is called a dune system or a dune complex. A large dune complex is called a dune field, while broad, flat regions covered with wind-swept sand or dunes with little or no vegetation are called ''ergs'' or ''sand seas''. Dunes occur in different shapes and sizes, but most kinds of dunes are longer on the stoss (upflow) side, where the sand is pushed up the dune, and have a shorter ''slip face'' in the lee side. The valley or trough between dunes is called a ''dune slack''. Dunes are most common in desert environments, where the lack of moisture hinders the growth of vegetation that would otherwise interfere with the development of dunes. However, sand deposits are not restricted to deserts, and dunes are also found along sea shores, along streams in semiarid climates, in areas of glacial outwash, and in other areas where poorly cemented sa ...

Eutrophication
Eutrophication is the process by which an entire body of water, or parts of it, becomes progressively enriched with minerals and nutrients, particularly nitrogen and phosphorus. It has also been defined as "nutrient-induced increase in phytoplankton productivity". Water bodies with very low nutrient levels are termed oligotrophic and those with moderate nutrient levels are termed mesotrophic. Advanced eutrophication may also be referred to as dystrophic and hypertrophic conditions. Eutrophication can affect freshwater or salt water systems. In freshwater ecosystems it is almost always caused by excess phosphorus. In coastal waters on the other hand, the main contributing nutrient is more likely to be nitrogen, or nitrogen and phosphorus together. This depends on the location and other factors. When occurring naturally, eutrophication is a very slow process in which nutrients, especially phosphorus compounds and organic matter, accumulate in water bodies. These nutrients deriv ...

Lake Engure Nature Park
Lake Engure Nature Park is a protected park in Latvia covering , named for Lake Engure. It was designated as a nature spot in 1998. The natural park belongs to the Natura 2000 network which brings together natural sites or semi-natural of the European Union with great heritage value. The text establishing the creation of the Natura 2000 network, the European “habitats, fauna and flora” speaks of natural sites of “community interest”, referring to the “heritage value” of habitats. In the field of nature conservation, we can distinguish habitats, fauna and flora according to their rarity: habitats "of regional interest" are rare in one region, but may be present in abundance elsewhere. . The same goes for habitats "of national interest", then "of European interest". The Natura 2000 network therefore applies to protect rare ecological sites at European level, and representative of the natural heritage of the Member States of the European Union, by fauna and flora excepti ...
