Beaver reintroduction programs across Europe and North America are restoring wetland ecosystems. Their engineering activities create habitat for hundreds of species while their welfare during translocation requires careful management.
Beaver reintroduction welfare requires attention to both the translocation process and the welfare of beavers in their new environment. Live trapping involves capture stress, handling, anesthesia for health assessment, and transport - each representing welfare challenges managed by appropriate protocols. Released beavers must establish new territories in unfamiliar environments, sometimes encountering pre-existing resident beavers who may be aggressive. The long-term welfare of successfully established beaver populations is excellent - beavers in appropriate habitat with sufficient water and vegetation thrive and reproduce successfully. Conflict with landowners, when it results in lethal control, represents a welfare cost that compensation and management programs seek to avoid.
