Piejūra
Dabas parks Piejūra () is a nature park along the Gulf of Riga in Latvia founded in 1962. It is a protected nature reserve and a Natura 2000 location. The park stretches over an area from Riga, through Carnikava Municipality, and up to Saulkrasti. It is a popular seasonal recreation location, notably for beach access. The park is notable for its protected biotopes, particularly its dunes and boreal forests. The park's conservation plan for 2020 onwards was developed under the "The LIFE Programme, LIFE CoHaBit" project. Location The nature park is a protected area designated as a nature reserve in Latvia, as well as a Natura 2000 territory. It is the third oldest nature park in Latvia. The park was formed primarily for the preservation of biotopes. A concrete goal is to further the coexistence of oligotrophic to mesotrophic plants in mineral-starved mesotrophic lakes and their coasts. The area of the park is .

Carnikava Municipality
Carnikava Municipality ( lv, Carnikavas novads) is a former municipality in Vidzeme, Latvia. The municipality was formed in 2006 by reorganization of Carnikava parish, Carnikava Parish of the Riga District, with the administrative centre being Carnikava. The population in 2009 was 6,261 people. The parish itself was created in 1992 after splitting from Ādaži Parish. After the municipal reform of 2009, the districts were abolished and the Municipality became a national administrative unit. On 1 July 2021, Carnikava Municipality ceased to exist and its territory was merged into Ādaži Municipality as Carnikava Parish.

Eurasian Eagle-owl
The Eurasian eagle-owl (''Bubo bubo'') is a species of eagle-owl that resides in much of Palearctic, Eurasia. It is also called the Uhu and it is occasionally abbreviated to just the eagle-owl in Europe. It is one of the largest species of owl, and females can grow to a total length of 75 cm (30 in), with a wingspan of 188 cm (6 ft 2 in), with males being slightly smaller.''Owls of the World: A Photographic Guide'' by Mikkola, H. Firefly Books (2012), This bird has distinctive ear tufts, with upper parts that are mottled with darker blackish colouring and tawny. The wings and tail are barred.

Songbird
A songbird is a bird belonging to the suborder Passeri of the perching birds ( Passeriformes). Another name that is sometimes seen as the scientific or vernacular name is Oscines, from Latin ''oscen'', "songbird". The Passeriformes contains 5000 or so speciesEdwards, Scott V. and John Harshman. 2013. Passeriformes. Perching Birds, Passerine Birds.

Water Bird
A water bird, alternatively waterbird or aquatic bird, is a bird that lives on or around water. In some definitions, the term ''water bird'' is especially applied to birds in freshwater ecosystems, although others make no distinction from seabirds that inhabit marine environments. Some water birds (e.g. wading birds) are more terrestrial while others (e.g. waterfowls) are more aquatic, and their adaptations will vary depending on their environment. These adaptations include webbed feet, beaks, and legs adapted to feed in the water, and the ability to dive from the surface or the air to catch prey in water. The term ''aquatic bird'' is sometimes also used in this context. A related term that has a narrower meaning is waterfowl. Some piscivorous birds of prey, such as ospreys and sea eagles, hunt aquatic prey but do not stay in water for long and lives predominantly over dry land, and are not considered water birds. The term waterbird is also used in the context of conserv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird Migration
Bird migration is the regular seasonal movement, often north and south along a flyway, between breeding and wintering grounds. Many species of bird migrate. Migration carries high costs in predation and mortality, including from hunting by humans, and is driven primarily by the availability of food. It occurs mainly in the northern hemisphere, where birds are funneled onto specific routes by natural barriers such as the Mediterranean Sea or the Caribbean Sea. Migration of species such as storks, turtle doves, and swallows was recorded as many as 3,000 years ago by Ancient Greek authors, including Homer and Aristotle, and in the Book of Job. More recently, Johannes Leche began recording dates of arrivals of spring migrants in Finland in 1749, and modern scientific studies have used techniques including bird ringing and satellite tracking to trace migrants. Threats to migratory birds have grown with habitat destruction, especially of stopover and wintering sites, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
European Union
The European Union (EU) is a supranational political and economic union of member states that are located primarily in Europe. The union has a total area of and an estimated total population of about 447million. The EU has often been described as a ''sui generis'' political entity (without precedent or comparison) combining the characteristics of both a federation and a confederation. Containing 5.8per cent of the world population in 2020, the EU generated a nominal gross domestic product (GDP) of around trillion in 2021, constituting approximately 18per cent of global nominal GDP. Additionally, all EU states but Bulgaria have a very high Human Development Index according to the United Nations Development Programme. Its cornerstone, the Customs Union, paved the way to establishing an internal single market based on standardised legal framework and legislation that applies in all member states in those matters, and only those matters, where the states have agree ...

Alluvial River
An alluvial river is one in which the bed and banks are made up of mobile sediment and/or soil. Alluvial rivers are self-formed, meaning that their channels are shaped by the magnitude and frequency of the floods that they experience, and the ability of these floods to erode, deposit, and transport sediment. For this reason, alluvial rivers can assume a number of forms based on the properties of their banks; the flows they experience; the local riparian ecology; and the amount, size, and type of sediment that they carry. At a smaller spatial scale and shorter time scale, the patterns of water movement, from events such as seasonal flooding, create different patches of soils that range from aerobic to anaerobic and have differing nutrients and decomposition rates and dynamics. When looking at larger spatial scales, the topographic features have been created by glacial events, such as glaciation and deglaciation, changes in sea-levels, tectonic movements, and other events that o ...

Littorina Sea
Littorina Sea (also Litorina Sea) is a geological brackish water stage of the Baltic Sea, which existed around 7500–4000 BP and followed the Mastogloia Sea, a transitional stage of the Ancylus Lake. This stage and form of the body of water is named after common periwinkle (''Littorina littorea''), then a prevailing mollusc in the waters, which indicates its salinity.

Baltic Ice Lake
The Baltic Ice Lake is a name given by geologists to a freshwater lake that evolved in the Baltic Sea basin as glaciers retreated from that region at the end of the last ice age. The lake existed between 12,600 and 10,300 years Before Present (BP). The Baltic Ice Lake is one of a number of water stages that eventually resulted in the modern Baltic Sea. After the Baltic Ice Lake came the Yoldia Sea (10,300–9,500 BP), the Ancylus Lake (9,500–8,000 BP), the Mastogloia Sea (8,000–7,500 BP), the Littorina Sea (7,500–4,000 BP) and finally the Baltic Sea (4,000 BP–present day). Phenomena related to ice lake and sea formation The term lake is used to mean a body of primarily fresh water. A sea is filled with brackish or salt water. In the history of the Baltic Sea, the distinction is not always clear. Salinity has varied with location, depth and time. The main factors are the advance or recession of the Scandinavian glacier and the isostatic sinking of the landforms due ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aleurite
Aleurite is an unconsolidated sediment with a texture intermediately between sand and clay, similar to silt, with particle sizes ranging from . Etymology The name aleurite is derived from the Greek word ''aleuron'', meaning "flour". Description The term aleurite is mainly used in Russian geology, where it is described from the Baltic and Kara Seas,Stein et al., 1996, p.53Sviridov & Emelyanov, 2000, p. 211 and as a derivative in Mongolia, such as the Dushihin Formation, where it occurs in lenses.Builjasutuin-Khuduk in the Aleurite primarily comprises mineral grains ( |
Gauja
The Gauja River ( et, Koiva jõgi, german: Livländische Aa) is a river in the Vidzeme region of Latvia. It is the only large river of Latvia that begins and ends its flow in Latvia. Its length is 460 km, of which 93.5 km (approximately one-fifth) are in the Gauja National Park. In this part, the Gauja River flows through the Gauja valley, which is 1 to 2.5 km wide, and the maximum depth near Sigulda is 85 m. Thus, Gauja is the longest river of Latvia when we count only the parts of the river in the country's territory. Daugava has only 367 km in Latvia, while the whole river is over 1000 km. The sandstone rocks on the banks of the Gauja and its adjoining rivers started forming 370 to 300 million years ago during the Devonian period. History Before the 13th century, the Gauja River used to serve as a trade route and border river between the Livonian and Latgalian lands. In some territories, they used to live mixed together.
