Renaturation Werraaue: Formerly inner-German border  becomes  green  oasis

Speciesprotection, archaeology and warfare exploration –  many  aspects have to be taken into account in the restoration of the Werraaue  n. Experts from Tractebel Hydroprojekt  accompany the project.

On a section of the  "Green Band"  near Untersuhl  -  once within Germany  - en  the Bachläufe  Weihe and  Rhedengraben  getback their  original  Bett. The  waters become more diverse, permeable and attractivefor the different animal species.  The project is a compensatory measure for the construction of the valleysperre Leibis/Lichte in Thuringia.

The aim of the restoration  is to  createa floodplain landscape  with  typicaln  watercoursesn and natural areasn.  In the future, the rivers should be able to develop in an independent dynamic way and become ecologically durchable    again.  The planning  takes into account the existing protected areas - nature and bird protection as well as fauna-flora habitat  (FFH). At the same time, it supports them in their conservation and development objectivesn.

Carefuls approach
After about thirteen  years of planning, work began on the construction preparation for Tractebel Hydroprojekt:  Avoid protective fences, asss  amphibien reach the construction site. The ground  was examined for weapons. Ein Biberdamm moved,  because  it was directly in the area of abridge to bedemolished. This  is followed by the earthworks quickly. These will be largely completed by the end ofFebruary  2021, so that the protected areas can start the new growing season as undisturbed as possible.

During theconstruction work, in addition to the Combat equipment service, archaeologists  also keep an eye on the project. In the floodplains and gravel terraces, testimonies from prehistory and early history as well as  recent  cultural monuments can be expected. On behalf of the Thuringian long-distance water supply,  these  activities  are coordinated on site.   The experts of Tractebel Hydroprojekt  are available as contact persons for the authorities. Thedrafts of  display boards and a plan for the maintenance of measures are also among the tasks of the water project experts.

In the e-ezelnen they monitor and coordinate during the construction phase:

  • Mahd, felling and grubging of woods
  • Decommissioningand disposal (e.g.sewage pipe, bridge, foundation border tower)
  • Hydraulic engineering works (e.g.gutter laying, new open clot, safety construction)
  • Landconstruction and surface work (e.g.terrain modelling on around 32,000 m2, installation secondary floodplain, floodplain, pond field)
  • Um's-rich plantings and sowing

Work on the   1.5 kilometre long section of the floodplain landscape is expected to be completed in  autumn  2021.

 

 

At Untersuhl,  the plans  of Tractebel Hydroprojekt transform an  area of the once inner German border into a lively natural landscape.
