Switzerland is facing rising conflicts between its growing beaver population, now at around 5,000, and human settlements. A new algorithm developed by biologist Christof Angst helps predict potential flooding risks linked to beaver dams. While authorities prioritize mild interventions to manage issues, the algorithm also reveals ecological benefits, such as improved groundwater levels in hilly regions. The initiative aims to foster coexistence between beavers and residents, emphasizing a need for careful assessments to mitigate risks while allowing beavers to thrive.
