Habitat restoration in limestone quarries

Habitat restoration in limestone quarries

Guidelines for Business Activities: Limits to impact restoration

Context: A cement company has holdings in important limestone areas of Bavaria, Germany, adjacent to a Natura 2000 site (a regional KBA identified for birds). Restoration could virtually double the area of protected limestone habitats and increase ecological connectivity.


Several important species are currently at risk, including birds such as the Woodlark (Lullula arborea), Tree Pipit (Anthus trivialis), Wryneck (Jynx torquilla), and Rock Bunting (Emberiza cia); the Smooth Snake (Coronella austriaca); and many rare plants.

Responses to date:

  • Restoration of an old quarry and surrounding area, testing a mixture of active and passive restoration.
  • Maintenance of important calcareous low-nutrient meadows through appropriate management strategies.
  • Monitoring and mapping of birds and other target species to establish a baseline and record trends and changes.
  • Production of maps, flyers, and other educational materials and implementation of educational activities with children and other groups.
  • Identification of target and indicator species to facilitate more effective monitoring.

The project is a partnership between BirdLife International and HeidelbergCement
