The Dal River is a river in central Sweden that flows from the north of Dalarna and runs into the sea in northern Uppland; it is commonly considered to be the southern border of Norrland. The northern part is split into two rivers: Österdalälven and Västerdalälven. The two connect in Djurås. It is over long — the second longest river in Sweden, and has a hydropower potential of 1420 megawatts, of which 2/3 is utilized. The largest power plant is located at the Trängslet Dam. Dalälven has been significant historically as a raft transport route. Nedre Dalälven River Landscape, Sweden, covers 308,000 ha with a mixture of wetlands, rivers, lakes, flood plains and productive forests. It includes Lake Hovran and Färnebofjärden Bay Ramsar site.
The region boasts high biodiversity, while the river forms a clear border zone between the northern and southern flora and fauna of Northern Europe. Agriculture and forestry activities have evolved as a result of changes in the steel and iron industries.
More than 100 ‘Leader+ projects’ designed for sustainable development testify to the high dynamism of the region. The biosphere reserve benefits from a highly participatory governance system as well as numerous partnerships with universities and research centres for environmental monitoring.
