The Asey brick building nature reserve is a nature reserve in the middle of a residential area north of the Ruhr in the Essen district of Kettwig . It is located on the site of a former brickworks , in which slate was extracted until 1972 .

status

On the website of the Lower Landscape Authority of the city of Essen, the brickworks Asey is listed as a nature reserve; the "Nature Reserve Ordinance on Asey Brickworks" from 1988 is also available here.

In the specialist information system of the State Office for Nature, Environment and Consumer Protection North Rhine-Westphalia (LANUV), the protected area was managed under the identifier E-004 until a few years ago. In the “List of all NSG in the district / independent city of Essen” published by LANUV aktuell (December 2015), however, it is missing; the page with detailed information linked from this list until it was deleted is currently not publicly available.

description

The size of the protected area is given as 3.6 hectares and 7.2 hectares, respectively. Geographically, it is a Siepental that has been shaped by claystone mining , which is divided into three south-facing mining terraces and has numerous small still waters and several springs. In addition to a small red oak forest in the northeast, ruderal vegetation and pioneer forest dominate .

The protected area is completely fenced and not accessible to the public.

Species and threats worthy of protection

Despite its small size, the protected area has a significant wealth of amphibian and dragonfly species due to the diversity of its waters . Among the nine amphibian species there are the specially protected species Fire Salamander , palmate newt , crested newt and natterjack toad , and in the Red List as "endangered" classified midwife toad . The 29 dragonfly species include the falcon dragonfly , the little rush damsel , the common winter dragonfly and the peat mosaic damsel listed as "endangered" on the Red List .

Hazards result from the small area and isolation of the area, from eutrophication as a result of atmospheric inputs, and above all from natural succession , in particular from silting up and overgrown by the small still waters.

Inspection by the BSWR 2014

A study conducted in 2014 committing the protected area by the Biological Station Western Ruhrgebiet (BSWR) served primarily the monitoring of the midwife toad , which still has an estimated in the 1990 population size had more than 25 animals. Evidence for the continued existence of the species was not found during this inspection, but it is considered possible. Since the maintenance measures carried out by the Lower Landscape Authority are considered to be beneficial in principle for the preservation of the amphibians, the BSWR recommends continuing the monitoring of the midwife toad.

The following amphibian species were found during the inspection: mountain newt , pond newt , common toad , natterjack toad and water frogs . Two blindworms have also been spotted in their daytime hiding spots.

Protection goals

According to the "Ordinance on the nature reserve 'Asey brick factory'", the establishment as a protected area is required

  • to preserve wetlands and small bodies of water as a habitat for swamp and aquatic plants, aquatic insects and other invertebrates,
  • to maintain and promote the community of natterjack toads and other amphibians,
  • to maintain valuable stocks of regionally rare and / or endangered plant species and to safeguard the diverse location pattern as a habitat and food biotope,
  • to preserve valuable woody plants and to protect against excessive foreign immigration,
  • to ward off harmful effects on the communities of the former brickworks,
  • for the scientific observation of the plant communities and the natural succession stages,
  • to restore a near-natural condition of the areas previously used as brickworks and quarries.
