Project summary
The Regional Water Authority Kronach was responsible for restoration measures undertaken. Starting in 1990, areas along the river were purchased in preparation for future restoration plans. Bank paving was removed and channel width increased to allow for the formation of highly diverse marginal habitats such as gravel bars and backwater areas. This also included reconnection of historic meanders, creation of multi-thread channels and increasing connectivity to floodplains. Overall a great increase was seen in geomorphological diversity and habitat potential. Between 1992 and 2008 the total length of restored sections reached 18km, and a floodplain area of 120ha.
The reasons for the particular success of this project are that restoration was not constrained by the usual site or catchment scale problems centred around land use and in usual difficulty in re-connecting flood plain and backwater areas due to land ownership.
