Aisle
As a swath or as a frame is referred to in forestry a tree-free strips (Durchhau, gap growth interruption) in the forest . The aisle is significantly longer than it is wide, which makes it different from a clearing . It can be of natural origin or it can be created artificially.
Origin and function
A lane can be created by clearing the trees by cutting down a lane through the forest . A storm or tornado , for example , which knocks over the trees over a long distance, can be considered as a natural cause of aisles . Aisles usually run roughly in a straight line. They are often found as forest stand boundaries between forest areas that are planted with different tree species. Other boundaries can also be formed or marked by an aisle; For example, the course of the former inner-German border is still recognizable today through aisles in many areas.
A laid path, e.g. As a Rückeweg lead; however, aisles are often cut specifically for the construction of overhead lines , paths and roads, and lift aisles are cut for cable cars . In addition, wide aisles can prevent forest fires, so-called fire aisles prevent the fire from spreading. The continued use of paths or paths in the forest means that trees do not grow back at this point and a path is formed. The creation of large aisles and desert areas as access routes and places of accommodation for workers and heavy equipment plays an important role in the development of primeval forests for the extraction of raw materials ( logging , oil production ) and can, under certain circumstances, be ecologically questionable.
That cleared
In the Bavarian forests , unpaved aisles, so-called cleared , have been common since the beginning of the 19th century. They were set up wherever natural sections such as roads, parking and timber removal routes and the like were missing. At high altitudes, they were not recommended in a west-east direction because of the risk of wind throws. Cleared be in Bavaria with field names called. One example is the "Hornsmann clearing " in the Hofoldinger Forest near Munich, which is named after the lawyer and environmentalist Erich Hornsmann .
Crossings of the cleared are often referred to as Jagdsterne and sometimes have names that end in stern , such as Ludwigstern at the intersection of Ludwig Geräum and Prinz-Karl Geräum in Forstenrieder Park .
Artificial corridors as living spaces
Power transmission lines through forests are often seen only as an impairment to intact forests. However, they can represent valuable areas for soil lichens, as the forest creates a shield against nutrients and pollutants from agriculture, industry and traffic. This can result in target habitats such as grasslands and heaths that can only develop beyond agricultural use. However, this requires regular maintenance of the areas in order to avoid the growth of woody stands. Due to the remote location, there is hardly any pressure to use it.
Figurative meaning
The term aisle is also used in a figurative sense and then usually describes an access, breakthrough (see also breach ) or free space. Well-known expressions are for example:
- "Leave a trail of desolation"
- "A lane in the forest of rules"
- "Clear a path"
The aisle is also used as a metaphor in technical parlance . The term entry lane should be mentioned here .
