Over time, restored areas around the lake have been surveyed to decipher breeding wetland species. In 1981, Lake Rysjön was restored. From 1982, all breeding wetland birds have been monitored and production of young calculated. In recent years, the Bird Observatory has had closer co-operation with the provincial government. From 2009, we have done censuses on all wetland birds for the provincial government covering all parts of the wetland nature reserve.
