The Further Moor is a forest and wetland area in Langenfeld (Rhineland) , which is designated as a nature reserve of around 42 hectares (NSG identification ME-001). The FFH area DE-4807-304 Further Moor exists almost congruently , making the area part of the European Natura 2000 network of protected areas .
geography
The Further Moor is naturally located in the area of the Bergische Heideterrassen . Its core area is to the west of the A3 , south of the "Bergische Landstrasse" and the A 542 , east of the Troisdorf-Mülheim-Morsbroich-Opladen-Immigrath-Richrath-Speldorf railway of the former Rheinische Eisenbahngesellschaft , north of Hapelrath and northwest of Furth .
history
The Further Moor was placed under nature protection in 1937 due to its interesting moorland area . It is the remnant of what used to be a more extensive swamp and swamp landscape at the foot of the Bergisches Land , as the comparison of Xanten (1614) and the partition treaty of Düsseldorf (1624) show. At that time it was about the division of the state on the Lower Rhine under Brandenburg-Prussia ( Kleve , Mark and Ravensberg ) and Pfalz-Neuburg ( Berg and Jülich ). The councils recommended Brandenburg to decide in favor of the local area, " ... if this land is well provided with stately swamps and marshes that could keep an enemy away in times of war ".
Controversial point: raised or flat moor
After an inspection in 1955, the biologist and geologist Franz-Erwin Wagner came to the conclusion that the flat hollow of the Further Moor, viewed from the sand mountains, would lead to the assumption that it should be classified in the group of flat moors because it is typical of high moors No bulge. However, it should be remembered that it does not get its water from the groundwater , but from precipitation . But such water would speak for a raised bog . The stream that meanders through the moor (Galkhauser Bach) also rises 300–400 meters east of the A3, on the watershed between Langenfelder and Leichlingen area. The recent formation of the moor also speaks for the raised moor rather than a flat moor. It was only with the deforestation of the pines that it was able to develop from swampy areas. The flora of the moor also speaks for the presence of a raised bog: This is how he names the gagel ( Myrica gale ), the pale moss, also called peat moss ( Sphagnum ), the cranberry ( Vaccinium oxycoccos ), the spotted orchid ( Dactylorhiza maculata ), the ear lily ( Narthecium ossifragum ), the king fern ( Osmunda regalis ) and the round-leaved sundew ( Drosera rotundifolia ) as signs of the presence of a raised bog.
Engineers from the responsible motorway office report of large flows of groundwater coming from the Bergisches Land and crossing under the motorway in the direction of Further Moor. Since one could not master the water with conventional means, the motorway was built at this point with special strength to prevent it from "floating up". One now hopes that nature will somehow fix it itself, the responsible engineer literally said. A short time later, on the Troisdorf-Mülheim-Morsbroich-Opladen-Immigrath-Richrath-Speldorf railway line running parallel to the A3, it was possible to see how the water passages for Blockbach and Hardtbach had to be widened. These two facts alone speak against a raised bog, but rather in favor of a flat bog fed by groundwater, perhaps comparable to the Attemsmoor in Styria.
As the researcher's own argumentation shows, his point of view is not supported by experts. The majority of scholars consider the existence of a bog to be given with regard to the bog. Finally, both the cited reference above on the comparison and the partition contract as well as the name Furth for the path through the Further Moor also speak for a considerable age of the moor and thus for the prevailing opinion . However, the map made by the cartographer Karl von Müffling around 1820 (see topographical picture of the Rhineland ) is to be used to determine the age of the moor because it may have recorded peat mining, not very helpful because the place indicated refers to an undated, presumably Germanic ring wall . Finally, it should be added that at least the sundew can no longer be found in the Further Moor.
