Rhineland Nature Park
Rheinland Nature Park (''Naturpark Rheinland'') is a nature park in North Rhine-Westphalia, situated between Bergheim, Kerpen, Erftstadt, Euskirchen, Königswinter, Bornheim, Bonn, Brühl, Hürth, Frechen and Pulheim. It covers an area of about 880 km2. Ville-Seen-Platte Roughly translated, this would be the 'plateau of lakes in the Ville'. In the vicinity of Erftstadt, Brühl and Hürth many small and large lakes have been created due to coal mining. The reforestation of the area was begun in 1920 by planting beech, pine, oak and larch Larches are deciduous conifers in the genus ''Larix'', of the family Pinaceae (subfamily Laricoideae).

Hürth
Hürth is a town in the Rhein-Erft-Kreis, North Rhine-Westphalia, Germany. Hürth shares borders with the city of Cologne and is about 6 km to the southwest of Cologne city centre, at the northeastern slope of the natural preserve Kottenforst-Ville. The town consists of thirteen districts, once independent villages, and is distributed over a relatively large area. The municipal area is interspersed with lakes and stretches of forest.

Larch
Larches are deciduous conifers in the genus ''Larix'', of the family Pinaceae (subfamily Laricoideae). Growing from tall, they are native to much of the cooler temperate northern hemisphere, on lowlands in the north and high on mountains further south. Larches are among the dominant plants in the boreal forests of Siberia and Canada. Although they are conifers, larches are deciduous trees that lose their needles in the autumn. Etymology The English name Larch ultimately derives from the Latin "larigna," named after the ancient settlement of Larignum. The story of its naming was preserved by Vitruvius: It is worth while to know how this wood was discovered. The divine Caesar, being with his army in the neighbourhood of the Alps, and having ordered the towns to furnish supplies, the inhabitants of a fortified stronghold there, called Larignum, trusting in the natural strength of their defences, refused to obey his command. So the general ordered his forces to the assault. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pine
A pine is any conifer tree or shrub in the genus ''Pinus'' () of the family Pinaceae. ''Pinus'' is the sole genus in the subfamily Pinoideae. The World Flora Online created by the Royal Botanic Gardens, Kew and Missouri Botanical Garden accepts 187 species names of pines as current, together with more synonyms. The American Conifer Society (ACS) and the Royal Horticultural Society accept 121 species. Pines are commonly found in the Northern Hemisphere. ''Pine'' may also refer to the lumber derived from pine trees; it is one of the more extensively used types of lumber. The pine family is the largest conifer family and there are currently 818 named cultivars (or trinomials) recognized by the ACS. Description Pine trees are evergreen, coniferous resinous trees (or, rarely, shrubs) growing tall, with the majority of species reaching tall. The smallest are Siberian dwarf pine and Potosi pinyon, and the tallest is an tall ponderosa pine located in southern Oregon's Rogue Riv ...

Beech
Beech (''Fagus'') is a genus of deciduous trees in the family Fagaceae, native to temperate Europe, Asia, and North America. Recent classifications recognize 10 to 13 species in two distinct subgenera, ''Engleriana'' and ''Fagus''. The ''Engleriana'' subgenus is found only in East Asia, distinctive for its low branches, often made up of several major trunks with yellowish bark. The better known ''Fagus'' subgenus beeches are high-branching with tall, stout trunks and smooth silver-grey bark. The European beech (''Fagus sylvatica'') is the most commonly cultivated. Beeches are monoecious, bearing both male and female flowers on the same plant. The small flowers are unisexual, the female flowers borne in pairs, the male flowers wind-pollinating catkins. They are produced in spring shortly after the new leaves appear. The fruit of the beech tree, known as beechnuts or mast, is found in small burrs that drop from the tree in autumn. They are small, roughly triangular, and edible, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Open-pit Mining
Open-pit mining, also known as open-cast or open-cut mining and in larger contexts mega-mining, is a surface mining technique of extracting rock or minerals from the earth from an open-air pit, sometimes known as a borrow. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining. Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface. It is applied to ore or rocks found at the surface because the overburden is relatively thin or the material of interest is structurally unsuitable for tunnelling (as would be the case for cinder, sand, and gravel). In contrast, minerals that have been found underground but are difficult to retrieve due to hard rock, can be reached using a form of underground mining. To create an open-pit mine, the miners must determine the information of the ore that is underground. This is done through drilling of probe holes in the ground, then plotting ea ...

Coal
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous ( Pennsylvanian) and Permian times. Many significant coal deposits are younger than this and originate from the Mesozoic and Cenozoic eras. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energy and over a third of its electricity. Some iron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pulheim
Pulheim (; Ripuarian language, Ripuarian: ''Pullem'') is a town in the Rhein-Erft-Kreis, North Rhine-Westphalia, Germany. Since the 1920s, a large substation of the ''Rheinisch-Westfälisches Elektrizitätswerk AG'' (RWE) is located at Pulheim. It is the end of the north south powerline and a large control center for the power grid of the RWE. In the communal reform of 1975, several previously independent municipalities were added to the municipality Pulheim, which received city rights in 1981. Pulheim consists of 12 quarters (''Stadtteile''), including Brauweiler, Geyen and Stommeln.

Frechen
Frechen (; Ripuarian: ''Frechem'') is a town in the Rhein-Erft District, North Rhine-Westphalia, Germany. Frechen was first mentioned in 877. It is situated at the western Cologne city border. It is the site of the 1257 Battle of Frechen between Conrad von Hochstaden, Archbishop of Cologne and the people of the town. In the 16th century it acquired a name for its terra cotta artifacts, especially the " Bartmannskrug" (beardman jug). In the late 18th century lignite was industrially mined. Digging for lignite dominated the city's economy until the end of the 20th century. In 1891 the first briquette factory was opened. On 2 September 1951 Frechen received its city-rights including the villages of Bachem, Hücheln and Buschbell. On 1 January 1975 the nearby villages of Grefrath, Habbelrath, Königsdorf and Neufreimersdorf were also incorporated. From the 1980s onwards an increasing number of industrial, commercial and service enterprises choose Frechen as their location, so that t ...

Kottenforst Station
The Kottenforst is a large forest, about 40 km² in area, to the south, west and north of the city of Bonn in Germany. It is part of the Rhineland Nature Park (1,045 km²) and forms its eastern side. Geography The Kottenforst is the southern part of a highland region that lies about 150 to , and known as the Ville, which drops steeply towards the east into the Rhine Valley, but whose western slopes descend more gradually towards the Swist and Erft rivers, forming a geological half-horst. The part of the natural region of Ville, which is not dominated by the brown coal mining of the Rhenish Brown Coal Field, is also called ''Waldville''. The Kottenforst is divided into a southeastern section between Meckenheim, Bad Godesberg and Bonn, into which areas of natural open country intrude in places, such as the Katzenlochbach Valley, and a northern area between Heimerzheim, Buschhoven and Alfter. Between the two areas lies the village of Witterschlick. References ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bonn
The federal city of Bonn ( lat, Bonna) is a city on the banks of the Rhine in the German state of North Rhine-Westphalia, with a population of over 300,000. About south-southeast of Cologne, Bonn is in the southernmost part of the Rhine-Ruhr region, Germany's largest metropolitan area, with over 11 million inhabitants. It is a university city and the birthplace of Ludwig van Beethoven. Founded in the 1st century BC as a Roman settlement in the province Germania Inferior, Bonn is one of Germany's oldest cities.
