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, Riga, 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 Russia, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Urban Park
An urban park or metropolitan park, also known as a city park, municipal park (North America), public park, public open space, or municipal gardens (United Kingdom, UK), is a park or botanical garden in cities, densely populated suburbia and other municipal corporation, incorporated places that offers open space reserve, green space and places for recreation to residents and visitors. Urban parks are generally Landscape architecture, landscaped by design, instead of lands left in their natural state. The design, operation and maintenance, repair and operations, maintenance is usually done by government agencies, typically on the local government, local level, but may occasionally be contracted out to a park conservancy, "friends of" group, or private sector company.

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, espe ...

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 ...

Pulsatilla Pratensis
The genus ''Pulsatilla'' contains about 40 species of herbaceous perennial plants native to meadows and prairies of North America, Europe, and Asia. Common names include pasque flower (or pasqueflower), wind flower, prairie crocus, Easter flower, and meadow anemone. Several species are valued ornamentals because of their finely-dissected leaves, solitary bell-shaped flowers, and plumed seed heads. The showy part of the flower consists of sepals, not petals. The common name ''pasque flower'' refers to its flowering period in the spring during Passover (in ''pāsaḥ''). Taxonomy The genus ''Pulsatilla'' was first formally named in 1754 by the English botanist Philip Miller. The type species is '' Pulsatilla vulgaris'', the European pasque flower. The genus is placed in the tribe Anemoneae within the family Ranunculaceae. The tribe has been shown repeatedly to be monophyletic in molecular phylogenetic studies, but the number of genera recognized within the tribe and their relatio ...

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, ''Quercus rubra'' 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, with small disjunct lowland populations in northern Poland. Its life span has been confirmed to be close to 1000 years, with ages of around 2000 years likely. Description ''Larix decidua'' is a medium-size to large deciduous Pinophyta, coniferous tree reaching 25–45 m tall, with a trunk up to 1.5 m diameter (exceptionally, to 53.8 m tall and 11.20 m girth [3.56 m diameter]). The crown is conic when young, becoming broad and often irregular 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 only 1–2 mm long with only a single bud. The leaf, leaves are needle-like, light green, 2–4 cm long which turn bright yellow before they fall in the autumn, leavin ...

Ecological Succession
Ecological succession is the process of how species compositions change in an Community (ecology), ecological community over time. The two main categories of ecological succession are primary succession and secondary succession. Primary succession occurs after the initial Colonisation (biology), colonization of a newly created habitat with no living organisms. Secondary succession occurs after a Disturbance (ecology), disturbance such as fire, habitat destruction, or a natural disaster destroys a pre-existing community. Both consistent patterns and variability are observed in ecological succession. Theories of ecological succession identify different factors that help explain why plant communities change the way they do. Succession was among the first theories advanced in ecology. Ecological succession was first documented in the Indiana Dunes of Northwest Indiana by Henry Chandler Cowles during the late 19th century and remains a main Ecology, ecological topic of study.

Eutrophication
Eutrophication is a general term describing a process in which nutrients accumulate in a body of water, resulting in an increased growth of organisms that may deplete the oxygen in the water; ie. the process of too many plants growing on the surface of a river, lake, etc., often because chemicals that are used to help crops grow have been carried there by rain. Eutrophication may occur naturally or as a result of human actions. Manmade, or cultural, eutrophication occurs when sewage, Industrial wastewater treatment, industrial wastewater, fertilizer runoff, and other nutrient sources are released into the environment. Such nutrient pollution usually causes algal blooms and bacterial growth, resulting in the depletion of dissolved oxygen in water and causing substantial environmental degradation. Many policies have been introduced to combat eutrophication, including the United Nations Development Program (UNDP)'s sustainability development goals. Approaches for prevention and re ...

Littorina Sea
Littorina Sea (also Litorina Sea) is a geological brackish water stage of the Baltic Sea, which existed around 8500–4000 Before Present, BP and followed the Mastogloia Sea (initial Littorina Sea), a transitional stage from 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. Overview The last fully fresh water stage in the Baltic basin, the Ancylus Lake ended at 9,800 BP when salt water from the world ocean started entering the Mastogloia Sea in the Great Belt region commencing an initial Littorina Sea which as a saline or brackish sea continues to this day. These initial transgression (geology), transgressions were incomplete and occurred at different times in different areas of the Baltic basin lasting until 8.5 ka cal. BP. The transition timings from fresh to brackish water that mark the onset of the Littorina Sea are not yet cl ... [...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's existence was first understood in 1894. The lake existed between about 16,000 and 11,700 years ago with well defined evidence from the warming of the Bølling–Allerød Interstadial to the period of cooling called the Younger Dryas before the Holocene, the onset of which is close in time to the end of the ice lake. The lake drained into the raising world ocean on two occasions and when water levels became the same on the second, with a sea level passage in the Billingen region of southern Sweden, it became the Yoldia Sea. 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
