River Brusaån

Brusaån River is a tributary of one of the largest river systems in southern Sweden; – the Emån River system. Brusaån River are mainly surrounded by pine forests, however, around and in the city of Mariannelund there is also agricultural land in the vicinity of the stream as well as artificial land use. The approximately ten km long stretch of the Brusaån River, between the railway bridge at Högebro and the outlet in Lake Åsjön, is identified as Brusaån Natura 2000 area. However, it is only the river bed (no riparian zones included) are that are protected. The Natura 2000 area of Brusaån River domintaes by sections of fast running water (runs and riffles) and holds a relatively fast growing stock of brown trout (Salmo trutta). Along the stream there are habitats suitable for breeding dippers (Cinclus cinclus), kingfishers (Alcedo atthis) and grey wagtail (Motacilla cinerea).

Brusåan River is one of three areas in Jönköping County where the thick shelled river mussel (Unio crassus) have been found. The population constitutes a high conservation value since it occurs in a mixed population together with freshwater the pearl mussel, which is regarded as fairly unique situation at a regional scale. Thus, one major reason with the UC4LIFE-project is to improve the conservation status for the two mussel species and for otter (Lutra lutra).

The main purpose of the Natura 2000 area is to maintain and restore habitats to obtain favourable conservation status at a bio-geographic level for Margaritifera margaritifera, Unio crassus and Lutra lutra). The River Brusaån is one of three areas in the County of Jönköping where Unio crassus have been found. UC4LIFE-related resoration actions will focus on the removal of obstacles to obtain free dispersal routes for fish and mussels in River Brusaån.
