The Drava floodplains in Slovenia between Maribor and Ormoz˘ have been severely impacted by three large reservoirs built in the 1970s and 80s for hydropower generation. However, remnants of characteristic riverine habitats and species have been preserved in the old riverbed, the so-called “Stara Drava” (Old Drava), which are protected as Natura 2000 sites. The impressive Borl castle above the Drava dates back to 1199.
