From October 2017 to October 2018, bog-moss and other mire plants were reintroduced in degraded part of mire in total area of 1 ha using adapted the so called Canadian method. Reintroduction process starts with site preparation and removal of dense cover of dwarf-shrubs, later Sphagnum fragments are planted with certain distance from each other and finally covered by fresh straw.

Results one season after experiment show that dry summer of 2018 was not favourable to part of Sphagnum fragments that have died out. However, dry Sphagnum cushions serve as substrate of other mire plants like Drosera rotundifolia, Rhynchospora alba, Rubus chamaemorus, Calluna vulgaris and others.
