fauna

The aim of the project was to create a various structured landscape with a mosaic of large optimal partridge habitats in the Vohnenbronnen quarry.

Holcim France has planned to progressively rehabilitate the site as part of the active operations with the following goals: full rehabilitation of the area and overall conservation of natural habitats and increase of available fauna and flora.

The quarry has been active since the early 1970's and careful monitoring of fauna and flora on rehabilitated areas and surrounding environment has been conducted for the last 5/7 years.

Built in response to the condition of the old mine (and in anticipation of conditions very likely to be imposed), an artificial bat cave is intended to provide an alternative long-term safe haven for bats.

Evaluation of the fauna during different stages of quarry recovery and comparison with natural habitats.

Wherever possible the worked out faces are sympathetically restored for both habitat improvement and softening of the visual impact so as to blend in with the surrounding areas.

Quarry and Nature live to see – a nature adventure trail around a quarry.

The recultivation of the Weisenau quarry was already in its advanced stages before the initial rehabilitation plan changed. The basic principle of the new project was conservation of the already finished recultivated and renaturated areas, thus nature conservation.

The current quarry rehabilitation works aim to partially restore the original relief and the pre-existing ecological lawns of interest, similar to those of the neighboring Natura 2000 zones, as well as the creation of natural banks in the excavated pond.
