Beaver re-introduction in Sweden

Beaver dam in Sweden
Area characterisation: 

Several beaver systems  within the species distribution range in Sweden with a focus on the Vindelälven catchment (12,650 km2) in Northern Sweden. The surrounding area is mainly rural with few peri-urban sites.


A truly nature-based solution is implemented by allowing beavers to spread into desired areas, letting them restore degraded wetlands and small streams and ditches as well as forest landscapes.

This case study is one of 17 that are part of the EU Horizon2020 project MERLIN - Mainstreaming Ecological Restoration of freshwater-related ecosystems in a Landscape context: INnovation, upscaling and transformation


Beavers are not excluded from the desired areas and their engineering of the system is fully allowed

Potential impacts/benefits: 
  • improvement of aquatic-terrestrial linkages
  • riparian and channel restoration: flood protection, drought mitigation
  • biodiversity enhancement
  • recreation
NbS benefits 
  • Flood peak reduction
  • Reduce drought risk
  • Reduce flood risk
  • Reduce run-off
  • Restoring ecosystems and their functions
  • Increase Biodiversity
