Abstract

Beaver reintroduction has emerged as a promising nature-based solution to address ecosystem degradation, enhance biodiversity, and mitigate the impacts of climate change. This thesis explores beaver reintroduction's economic and ecological potential, focusing on its role in addressing water scarcity and enhancing ecosystem restoration in North America and Europe. As ecosystem engineers, Beavers create wetlands that provide critical habitats for various species, regulate water flow, improve water quality, and sequester carbon. Their ability to restore hydrological functions, such as groundwater recharge and streamflow stabilization, has significant implications for regions facing water shortages, such as the Colorado River Basin in the U.S. and drought-prone areas in Europe. Additionally, beaver-engineered wetlands promote biodiversity by supporting fish, amphibians, birds, and other wildlife while helping reduce the impacts of floods and droughts. This thesis presents case studies from Oregon, Nevada, and Scotland, illustrating both the challenges and successes of beaver reintroduction projects. It also discusses the economic benefits, including the potential cost savings compared to traditional river restoration methods and the growing eco-tourism opportunities linked to beaver habitats. Despite the ecological benefits, beaver reintroduction often faces resistance, particularly from agricultural communities concerned about flooding and crop damage. Effective management strategies, including non-lethal approaches and stakeholder collaboration, are essential for balancing the benefits of beavers with human interests. The findings of this thesis highlight the importance of beavers as a cost-effective, sustainable solution for ecosystem restoration and climate resilience, advocating for their broader inclusion in environmental management policies.
