Group guideline for the promotion of biodiversity - Business and ...

quarry. It is advisory to mark shallow dry areas orareas with temporary waters as rest zones. Rocksand steep faces may even be excluded from quarryingfor a while. The separation of such rest zonesfrom areas still active is achieved by ramparts madeof spoil, by large rocks or linearly stapled wood clippings.This allows specialised habitat communitiesto develop slowly.Selective Promotion of SpeciesThe more cavities and holes in the plant buildingswhere birds can slip in, the more animal speciescan benefit. Animals such as bats or birds, and withsome exceptions also reptiles and insects, shouldalways be tolerated unless they provide any kind ofdanger for the staff. Special nesting aids on buildings,rock faces or in woods may lure in designatedspecies.Soil ManagementAdvice on soil management before, during and afterquarrying is provided in section 4.4.After-use PlanningInflexible prescription and implementation ofafter-use planning needs to be replaced by a moreflexible handling of after-use concepts. This makesit possible to take spontaneous developmentof biological diversity into account on site afterthe cessation of quarrying and when it comes toreclamation.Further ReadingBDZ/VDZ (2002); Dav i s (ed.)
