birds

In 2005, a specialist environmental assessment was commissioned to record invertebrates, reptiles and amphibians, birds and mammals in the region around the existing quarry with a view to improving the management of them and their habitats.

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.

Recultivation of the quarry with the objective of creating unique nature and increase biodiversity.

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

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.
