A) Location

The Burgstall pit site is located in the foothills of the Frankenwald, and is in the "Obermainisches Hügel-land" conservation area. The pit is approx. 2.5 km east of the market community of Mitwitz, and approx. 55 km north of Bayreuth. In terms of geology, the near surroundings of the quarry site were formed in layers during the Middle Buntsandstein (Lower Triassic) period. The sand grain size is subject to large variations. As a result of the geological subsoil, the soils are mainly dry, nutrient-poor, weakly buffered brown soils. 

B) Overview of Mining and Recultivation

The approved excavation surface amounts to approx. 60 ha, of which 40 ha are actively used. Mining takes place via dry extraction processes. The active mining is separated from the previous excavation surfaces by several powerful dams. These previous surfaces continue to be used as sludge ponds, and today form a large part of the regenerated areas. Today, a total of approx. 20 ha has already been rena-turated. Wetland biotopes and extensive succession zones, amongst others, have come into existence. 

The recultivation plan (2000), which aims to encourage the use of former mining sites as conservation areas, sets the following key objectives:

  1. Creation of sites for species of plants and animals which like warm, dry conditions, and optimisation of breeding habitats for cliff breeders 
  2. Creation and/ or preservation of exposed southern steep faces with a sandy substrate
  3. Creation of appropriate sites for wetland pioneer vegetation, and sparse, little overgrown areas and floor area
  4. Creation of a mosaic of wetland and dry sites in close proximity
  5. Creation of a mosaic of different succession stages (groves, grassland, reed beds, bodies of water)
