The Liebenauer Gruben are a nature reserve in the Lower Saxony municipalities of Estorf in the joint municipality of Mittelweser and Liebenau in the joint municipality of Liebenau in the district of Nienburg / Weser .

history

The German Nature Conservation Union applied for the Liebenau gravel pits to be designated as a nature reserve in 2006 . At the time, this was rejected by the Nienburg district as the responsible lower nature conservation authority for economic reasons.

Since the beginning of 2012 a procedure has been running to designate the area as a nature reserve "Liebenauer Gruben". The implementation was planned for October 2012 and decided on October 19 by the Nienburg district council. The district thus fulfilled its obligation to secure FFH areas also nationally. The ordinance on the nature reserve came into force on December 20, 2012. The nature reserve has the label HA 221. The responsible lower nature conservation authority is the district of Nienburg.

description

The site, which consists of four gravel pits, is located southwest of Nienburg / Weser to the left of the Weser in a Weser bend roughly between Weser-km 260.0 and Weser-km 261.5. It was created from 1969 through the wet mining of gravel and extends over an area of ​​around 100 hectares. Gravel mining in this area was ended in 2008 and the gravel pits were then recultivated . The gravel pits in the south of the conservation area, are "Wesermarsch" are mostly part of the FFH area "pond bat waters in the room Nienburg".

Since February 2009, the site has been funded by the NABU Foundation for National Natural Heritage , the Lower Saxony Lottery Foundation , BINGO! and many donors as well as funds from the district of Nienburg, to a large extent , have been acquired by the Naturschutzbund Deutschland , which has set up a protected area here. In total, this protected area is around 140 hectares.

Reclamation

The gravel pits are connected to each other and to the Weser by connecting channels. They are subject to river dynamics and are regularly flooded when the Weser floods. Riparian forest communities have already settled in parts of the gravel pits . An area previously used for agriculture was reforested by NABU Germany into a hardwood floodplain forest .

The gravel pits, which are up to 10 meters deep, were partially filled with material accumulated during the expansion of the Weser for the European ship , so that only one to two meters deep water zones and shallow water areas and numerous flat islands were created. The shallow water areas and siltation zones should also be occupied by reed beds . In addition, a breeding raft for common terns was anchored in one of the gravel pits. In addition, temporary still waters were created on the site as a habitat for amphibians and dragonflies . Fallow land and grassland areas can be found between the gravel pits . Lean sand lawns grow on higher, dry areas .

Flora and fauna

The former gravel mining area has developed into an important habitat for numerous animal and plant species. Numerous birds can be found here, some of which also breed here. The area is also important as a resting place for migratory birds . So here are u. a. Corncrake , lapwing , nightingale , red-backed shrike , river and Uferseeschwalbe, ringed plover , reed warbler , pipe and grasshopper warbler , Stonechat and Meadow Pipit home. Also Rothalsgans , avocets , egrets , grebes and black-necked grebe , Mittelmeermöwe , Sandpiper , Red and Black Kite and eagles have been observed. The white stork uses the area for foraging. The osprey has adopted the water landscape as a habitat. NABU installed a nesting platform for him on a former power pole.

Migrants and winter guests are various types of geese and ducks , including pygmy and goosander , bean goose as well as spoonbill and golden bell .

Dragonflies are numerous in the area of ​​the gravel pits, including blood-red darter , autumn damsel , great blue arrow and great royal dragonfly .

The waters are feeding habitats for the pond bat . The Liebenau gravel pits are also habitat for numerous plant species, including endangered species such as z. B. the swan flower and the blood-red cranesbill . Furthermore, u. a. Swamp sword lily , small grape hyacinth and rose mallow can be found.
