Mire restoration within the Sumava National Park, Czech Republic

National Id
Site name
Sumava National Park
The project coordinated by the Ministry of Environment involves a mire restoration program in the Sumava National Park, Czech Republic, The aim was the raise of the water table to a natural (per-drainage) level, decrease the fluctuations, and retain sufficient water in the mires especially during the driest periods. To make it possible, the activities carried out were restoration of natural (or near-natural) mire hydrology, enhancement of peat-forming vegetation and processes, conservation of natural mire biodiversity and involvement of the public into local mire conservation.

Performance impact estimation information
Water table measured manually in all boreholes at nearly fortnight intervals. Automatic gauging(at 1h intervals) by piezometers was used in a selected 49 boreholes. Water samples from boreholes, ditches, runoff profiles from drained sites and samples from streams were taken monthly for a detailed hydrochemical analysis, including content of main cations and anions, pH, conductivity and DOC. Runoff from drained sites as well as amount of precipitation were measuered continualy.

Both visitors and local people regularly attend †œMire Days†, which have been organised in the Å umava NP since 2008. In the ,rst half of such a mire day, people help with mire restoration a-er which they can visit undisturbed mires during the a-ernoon excursion.
Similar †œMire Weeks† have also been organised in collaboration with NGOs for already 8 years. *ese †œMire Weeks† are attended mainly by young people and students. In this way several hundred people from the whole Czech Republic have taken part in mire restoration

Key lessons
The target water table concept seems to be a useful tool in mire restoration especially in the case of bogs and various sloping mires.
Long-term monitoring including a pre-restoration period of several years is necessary to evaluate restoration success both in mires and adjacent habitats, for understanding ecological processes and complete cosystem response.
When assessing hydrochemistry efects of restoration on the catchment level, the various conditions of restored minerotrophic mires and bogs should be taken into consideration.

Information on increased water storage
The mean water table rose
Information on runoff reduction
The fluctuations in the water table were reduced, especially in the dwarf-shrub bog sites and wet forests. The water table beneath Trichophorum lawns remained at almost the same level, but also here fluctuations were reduced.
Water quality overall improvements
Positive impact-WQ improvement
Information on Water quality overall improvements
Increased concentrations of PO4, Al, Fe. Hydrochemical changes were found to be much more expressed in wet forest than peatbog. Long-term monitoring is necessary for understanding ecological processes and complete cosystem response.
