Ponds are being created as habitats and reproductive sites for amphibians. The subject of the call for tenders is the necessary earthwork and planting work, as well as measures for reptile protection and habitat management (mowing).

The compensation measure is permanently marked by delimitation piles. A temporary amphibious protection fence and a permanent amphibious defender will be built. The temporary amphibious fence is maintained and gradually dismantled.

The excavated earth masses from the future amphibian oaks will be installed in an immission protection wall to be built on site and subsequently sown.

The resulting topsoil is temporarily stored in a warehouse provided by the customer - in rented rents.

For reasons of species and biotope protection and related measures will be necessary for the earthworks and planting in a controlled construction in 2 stages.
