It is hardly expected in commercial and industrial areas. But it is still there. Why is that? For many decades we have been committing to groomed, intensive agricultural landscape, where flora and fauna have little chance of survival. Animal populations are searching for secondary habitats in areas such as the Freiburg industrial area Nord. Here, the gravel tracks offer ideal habitats for wall lizards, tall industrial buildings accommodate alpine swift and kestrel settlements, and rare biting insects and wild bees colonize the wastelands. The BIG project aims among other things to improve the living conditions for these species through different measures taken by the participating companies. To ensure there is opportunity for success, it is necessary to know which species are currently there. For this reason, specialist biologists were tasked with mapping, to determine where and which birds breed, wall lizard count and which wild bees find nectar and pollen on which host plants. In environments where there is planned expansion very soon, it does not make sense to carry out biotope type mapping. The potential analysis chosen here offers companies the various measures that have positive impacts on biodiversity and often enough on the well-being of employees as well.
