Description:

EU Biodiversity Strategy for 2030 is aiming to restore 25,000 km of free-flowing rivers across Europe. The important issue is which barriers should be prioritised for removal. In this study a set of socio-economic and environmental criteria was chosen to rank the dams on salmonid rivers in Lithuania and recommend them for removal. As these criteria usual contradict themselves the multi-criteria decision analysis tool was utilized. The results showed that the Anykščiai dam on the river Šventoji can be recommended to be removed first. The removal can significantly increase the salmonid population in the river Šventoji over significant stretch of the river. Also, this dam is in the protected area and is not listed as national heritage and does not have hydropower plant on it. Although, this study showed that dams with hydropower plants can also be recommended for removal.
