To date mining,
in particular open cast
mining, has influenced about 1 percent of Earth’s terrestrial
surface. Abandonment of arable land is another widespread phenomenon of
human impact on landscapes. Both driving forces have a great influence
on the respective landscapes and provide needs and opportunities for
diverse restoration programs. Distinct primary and secondary succession
processes can be observed in disturbed sites. Therefore, their
restoration should incorporate and respect spontaneous succession
processes. Besides mining, various other industrial activities leave
behind specific disturbed habitats, which need to be restored as well.
The session is focused mainly on the following topics and questions:
- Under what conditions is manipulation of
succession, both of the
physical-chemical environment and the biota, needed?
- In which cases is more convenient to
allow unassisted succession to
proceed?
- Under what circumstances is technical
reclamation the most convenient
solution?
- To which degree is succession predictable?
- How do different restoration targets
determine the restoration process?
- What is the influence of the surrounding
environment, especially as a
seed source, on the restoration process?
- What is the extent of in-site and
among-site variability of succession?
The overall aim of the session is to enhance incorporation of natural
processes (spontaneous succession) into scientifically informed
restoration programs.
