We successfully finished the first season of our interesting project working in mined as well as preserved peatbogs. Our aim is to find out which species of fungi, mosses and higher plants grow there and which species of butterflies occur there and, moreover, why some species do still not occur on the mined peatbogs. We also performed experimental sowing of berries of bog cranberry (Vaccinium oxycoccos) in selected peatbogs to find out if it does not grow there because it still has not spread there or because there are unsuitable conditions there. Hopefully, we will be able to answer this and many other questions in the next years.
