Abstract:

A geographic information system (GIS) provided framework for gathering and analysing of large dataset comprising all available recent mining sites in the Czech Republic. Biotope mapping was used as a main tool for prediction of conservation potential of mining sites. The proportion, type (natural vs modified by human, woodland vs non-woodland) and distance of biotopes up to 1 km distance from the edge of mining site have been evaluated. The information obtained from various maps was combined with relevés from selected mining sites (at least four relevés per locality) summarized in Database of Successional Series. Participation of target (i.e. grassland, woodland, wetland), and synanthropic species in relevés was calculated for each sampled locality. The results proved that only the distance to non-woodland biotopes up to 21 m from the edge of disturbed site had significant effect on participation of target species in the mining sites. Localities, where proportion of target species exceeded 50 %, were considered as perspective for nature conservation. The effectivity of this new method was verified on another dataset (less than 4 relevés per locality) and reached almost 70 %. This new approach can help with preliminary identification of localities with conservation potential but vegetation survey should be kept as integral part of each ecological restoration as effectivity of proposed method varied also among particular post-mining sites.
