Mežaparks (park)
Mežaparks ( Forest Park) is a large urban park in the Mežaparks neighbourhood of Riga, the capital of Latvia. The park is home to the open-air Mežaparks Great Bandstand and has Riga Zoo located next to it as well as access to Ķīšezers lake. The territory is covered with coastal dunes, much of it with boreal forests, both protected conserved biotopes. The territory began to be used for recreation in the 18th century and was added to Riga's territory in the 19th century. In 1901, the Mežaparks neighbourhood became Russian Empire's first architectural project to use the garden city movement. The area was expanded and developed during the first half of the 20th century, primarily serving as an elite sports complex. After World War II in 1949, the Soviet Government carried out a major expansion of the park and inaugurated it as a public park with many recreational areas and buildings. Up until the end of the 20th century, the park continued to serve as a public park. Althou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Urban Park
An urban park or metropolitan park, also known as a municipal park (North America) or a public park, public open space, or municipal gardens ( UK), is a park in cities and other incorporated places that offer recreation and green space to residents of, and visitors to, the municipality. The design, operation, and maintenance is usually done by government agencies, typically on the local level, but may occasionally be contracted out to a park conservancy, "friends of" group, or private sector company. Common features of municipal parks include playgrounds, gardens, hiking, running and fitness trails or paths, bridle paths, sports fields and courts, public restrooms, boat ramps, and/or picnic facilities, depending on the budget and natural features available. Park advocates claim that having parks near urban residents, including within a 10-minute walk, provide multiple benefits.

National Heritage Site
A national heritage site is a heritage site having a value that has been registered by a governmental agency as being of national importance to the cultural heritage or history of that country. Usually such sites are listed in a heritage register that is open to the public, and many are advertised by national visitor bureaus as tourist attractions. Usually such a heritage register list is split by type of feature (natural wonder, ruin, engineering marvel, etc.). In many cases a country may maintain more than one register; there are also registers for entities that span more than one country. History of national heritage listing Each country has its own national heritage list and naming conventions. Sites can be added to a list, and are occasionally removed and even destroyed for economic or other reasons. The concept of protecting and taking pride in cultural heritage is something that goes back to the Seven Wonders of the World, but usually it is only after destruction, especia ...

Platanthera Bifolia
''Platanthera bifolia'', commonly known as the lesser butterfly-orchid, is a species of orchid in the genus ''Platanthera'', having certain relations with the genus ''Orchis'', where it was previously included and also with the genus ''Habenaria''. It is a Palaearctic species occurring from Ireland in the west, across Europe and Asia to Korea and Japan. It is also found in North Africa. The name ''Platanthera'' is derived from Greek, meaning "broad anthers", while the species name, ''bifolia'', means "two leaves". Identification Lesser butterfly-orchids are not to be confused with the greater butterfly-orchid, which are about the same size. Lesser butterfly-orchids are distinguished by their two shining green basal leaves, especially of the hill form, which are shorter and broader and by the angle of the pollinia. The upper sepal and petals form a loose triangular hood above the pollinia, which lie parallel and close together, obscuring the opening into the spur, which is lon ...

Quercus Rubra
''Quercus rubra'', the northern red oak, is an oak tree in the red oak group (''Quercus'' section ''Lobatae''). It is a native of North America, in the eastern and central United States and southeast and south-central Canada. It has been introduced to small areas in Western Europe, where it can frequently be seen cultivated in gardens and parks. It prefers good soil that is slightly acidic. Often simply called red oak, northern red oak is so named to distinguish it from southern red oak (''Q. falcata''), also known as the Spanish oak. Northern Red Oak is sometimes called champion oak. Description In many forests, this deciduous tree grows straight and tall, to , exceptionally to tall, with a trunk of up to in diameter. Open-grown trees do not get as tall, but can develop a stouter trunk, up to in diameter. It has stout branches growing at right angles to the stem, forming a narrow round-topped head. Under optimal conditions and full sun, northern red oak is fast growing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Larix Decidua
''Larix decidua'', the European larch, is a species of larch native to the mountains of central Europe, in the Alps and Carpathian Mountains as well as the Pyrenees, with disjunct lowland populations in northern Poland and southern Lithuania. It is widely naturalized in Scandinavia. Its life span has been confirmed to be close to 1000 years (with claims of up to 2000 years) but is more often around 200 years. It is claimed that one of the larches planted by the second Duke of Atholl at Dunkeld in 1738 is still standing. Description ''Larix decidua'' is a medium-size to large deciduous coniferous tree reaching 25–45 m tall, with a trunk up to 1 m diameter (exceptionally, to 53.8 m tall and 3.5 m diameter). The crown is conic when young, becoming broad with age; the main branches are level to upswept, with the side branches often pendulous. The shoots are dimorphic, with growth divided into long shoots (typically 10–50 cm long) and bearing several buds, and short shoots ...

Pinus Strobus
''Pinus strobus'', commonly called the eastern white pine, northern white pine, white pine, Weymouth pine (British), and soft pine is a large pine native to eastern North America. It occurs from Newfoundland, Canada west through the Great Lakes region to southeastern Manitoba and Minnesota, United States, and south along the Appalachian Mountains and upper Piedmont to northernmost Georgia and perhaps very rarely in some of the higher elevations in northeastern Alabama. It is considered rare in Indiana. The Native American Haudenosaunee named it the "Tree of Peace". It is known as the "Weymouth pine" in the United Kingdom, after Captain George Weymouth of the British Royal Navy, who brought its seeds to England from Maine in 1605. Distribution ''P. strobus'' is found in the nearctic temperate broadleaf and mixed forests biome of eastern North America. It prefers well-drained or sandy soils and humid climates, but can also grow in boggy areas and rocky highlands. In mixed ...

Ecological Succession
Ecological succession is the process of change in the species structure of an ecological community over time. The time scale can be decades (for example, after a wildfire) or more or less. Bacteria allows for the cycling of nutrients such as carbon, nitrogen and sulphur. The community begins with relatively few pioneering plants and animals and develops through increasing complexity until it becomes stable or self-perpetuating as a climax community. The "engine" of succession, the cause of ecosystem change, is the impact of established organisms upon their own environments. A consequence of living is the sometimes subtle and sometimes overt alteration of one's own environment. Succession is a process by which an ecological community undergoes more or less orderly and predictable changes following a disturbance or the initial colonization of a new habitat. Succession may be initiated either by formation of new, unoccupied habitat, such as from a lava flow or a severe lan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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. A transgression of the Baltic approximately 4500 BP widened its ocean link, allowing it to reach a peak of salinity during the warmer Atlantic period of European climatology. At this peak, the sea bore twice the volume of water and covered 26.5% more land than it does today. As the period ended, the features of the modern coast appeared, including lagoons, spits, and dunes. Notable exceptions include steep terraces such as the Øresund where the recession of sea level exposes less dry land. During the period, temperate deciduous forest Temperate deciduous or temperate broad-leaf forests are a variety of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Mežaparks - Panoramio (2)
Mežaparks (german: Kaiserwald) is a neighbourhood of Northern District in Riga, the capital of Latvia. It consists of a residential area to the South and a large urban park to the North of the same name – Mežaparks. The neighbourhood is located on the western shore of Lake Ķīšezers. The name is literally translated as "forest park". The neighbourhood and park were built in the early 20th century and the area was originally called . It was one of the world's first garden cities. It had large number of Art Nouveau and Eclectic villas for upper class inhabitants of Riga. During the Second World War, the Kaiserwald concentration camp was located in this park, and many Jews, Gypsies, Communists, and other opponents of Nazi rule were murdered in these woods. Today it is still one of the wealthier areas of Riga, the Mežaparks Great Bandstand hosts the Latvian Song and Dance Festival in early July every five years. Mežaparks is also host to the Riga Zoo and its lakeside l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
