Koppången is a large mire complex with small lakes, peatlands and forests containing notable examples of wetland types in the European Boreal region, and specifically Natura 2000 habitat types such as aapa mires, transition mires and quaking bogs, bog woodland, and Western Taiga and Fennoscandian herb-rich forests with Norway spruce Picea abies. The Site supports long-term viable numbers of several lichens, bryophytes and macro-fungi. Nationally red-listed species include ruff Philomachus pugnax, wolverine Gulo gulo and Eurasian lynx. The extensive wetlands support important populations of many breeding bird and mammal species, which then re-colonize the surrounding semi-natural landscape. The Site stores and sequestrates carbon, contributing to global climate regulation, and it serves as an important moderator of heavy rainfalls. The open mires protect the natural old-growth forest from fires. Popular seasonal activities include cross-country skiing and dogsledding in winter, cloudberry and blueberry picking in summer, and elk and capercaillie hunting in autumn. The Site is of cultural interest and it has been traditionally used for haymaking. Two management plans for the overlapping Nature 2000 sites and Nature Reserve are being implemented. As a part of the EU co-funded “Life to Ad(d)mire” LIFE project, the natural hydrology of the Site has been restored by the blocking of ditches to prevent further drainage.
