Other Site Characteristics

Ljusnan, in this part of the river mostly called Mellanljusnan, between Korskrogen and Edeforsen runs in the upper part in a deep river channel (up till 50 m deep) through a thick fossile glacail river delta closely following the esker Ljusnanåsen and sometimes reaching the underlaying bedrock. As the river passes through Ljusdal the caracter of the surroundings changes from a At these points more or less wild rapids have arisen.The site is covered by the special provisions in the Swedish EnvironmentalCode, Chapter 4 on management of land and water for certain areas in Sweden: provisions on prohibition of exploitation for hydro-electricity purposes(Chapter 4, § 6 in the Environmental Code). There is no code (protectiontype) available under field 5.1 to register this kind of general protection.

4.2 Quality and importance

The river Ljusnan is one of the largest rivers in Sweden. The source lakes will be found in the southern part of the Swedish alpine region which is reflected in the flora as several alpine species can be found along the river. Ljusnan has a most valuable fauna with e. g. Lutra lutra. Even the fish fauna is valuable with a local form of Salmo trutta. Ljusnan is important to leisure fishing and different forms of tourism.There is a large season-bound flooding in spite of some power plants in the upper parts of the river.Ljusnan is of National interest to environmental care.

5.3 Site designation (optional)

The river Ljusnan is in this part intended to free development.Two bridges are planned to be built across the river within a few eyars. One of them at Ljusdal to improve the traffic situation and one at Edänge to replace an old and weak railway bridge and to rise in the standard of the railroad.
