Alsterån river

In Alsterån river LIFE CONNECTS aims to improve connectivity and river habitats to gain favorable consevation status for prioritised Nature 2000 habitat types and species, especially Atlantic salmon, European bullhead and Eurasian otter.

Alsterån river is located in the southeastern part of Sweden. The river is 125 km long and entirely a Nature 2000 area. The land use in the catchment area is dominated by forestry and smaller parts are covered by lakes and farmland. Alsterån river is one of the most valuable rivers in Kalmar county. Despite high natural values the river has been affected by acidification and alterations during a long time. As a result, long distances have been cleared of larger substrates and straithened. According to the latest classification (accordning to the Water Framework Directive, WFD) Alsterån river has a moderate status due to lack of connectivity, changed morphology and acidification. LIFE CONNECTS will remove barriers and improve habitats to create more natural habitats for plants and animals.

In Alsterån river 18 different fishspecies are present, including Atlantic salmon (Salmo salar), European river lamprey (Lampetra fluviatilis), European catfish (Silurus glanis), Brown trout (Salmo trutta), Spined loach (Cobitis taenia) and European bullhead (Cottus gobio). The populations of salmon has decreased for the last decade and is a prioritised species in the Habitat directive and management plan for the Nature 2000 sites in Alsterån river.

The measures conducted in LIFE CONNECTS in Alsterån river will increase the targeted species populations and improve the conservations status for prioritised Nature 2000 types and related species.
