Reintrodukce dvou cílových druhů na vytěžené rašeliništěVLKOVÁ, Ludmila January 2016 (has links)
Restoration of the extracted peat bog Soumarský most in the Šumava NP, Czech Republic, started in 2000 with blocking drainage ditches and increasing water table. There were installed 25 boreholes to measure water table fluctuations in monthly intervals. Around each borehole, vegetation record was made. Three specimens of Vaccinium oxycoccos and Andromeda polifolia, as typical peat bog species which disappeared during extraction, were planted. Moreover, seeds of the species were sown. Survivorship of the transplants and seedling emergence were related to the average water table and composition of vegetation around the boreholes. Results of the experiment showed capability of the species to be reintroduced by these ways. The ability to survive after four years was the highest around the water table of -14 cm. The plants mostly died in dry and too wet sites. This experiment shows the absence of species in the extracted peat bog is caused by dispersal, not habitat limitation. Results can be applied in next restoration attempts in this and comparable disturbed peat bogs.
