The River Otter Beaver Trial in England is a notable example where proactive engagement and appropriate communication with local stakeholders helped mitigate conflicts and fostered a sense of shared responsibility (Auster et al., 2020). In Scotland, the planned reintroduction of beavers in Knapdale, which was science-led and involved extensive stakeholder engagement, faced fewer conflicts compared to unplanned reintroductions in Tayside and the Highlands (Coz and Young, 2020). These examples underscore the importance of structured reintroduction processes and the need for effective discussions involving all stakeholders to agree on long-term conservation plans (Coz and Young, 2020). In Italy, the potential range expansion of the Eurasian beaver has been modeled to identify areas most likely to be colonized in the near future. This proactive approach helps environmental managers focus on monitoring and mitigating potential conflicts before they arise (Falaschi et al., 2023). Additionally, the use of beavers in natural flood management (NFM) has been explored in England, where downstream communities have been engaged to understand their perspectives and integrate beaver activities into broader flood management strategies (Auster et al., 2020). This catchment-based approach to beaver management and public engagement has shown promise in facilitating coexistence and maximizing the benefits of beaver activities for flood alleviation (Auster et al., 2020). 10 Future Research Directions 10.1 Gaps in current knowledge Despite the extensive research on beavers as ecosystem engineers, several gaps remain in our understanding of their impacts and management. One significant gap is the variability in hydrological responses to beaver activity across different landscapes and seasons. Studies have shown that beaver dams can attenuate flood flows and reduce peak flows, but the extent of these effects varies spatially and temporally, necessitating further research to understand these dynamics better (Puttock et al., 2021). Additionally, while the role of beavers in enhancing biodiversity is well-documented, there is limited knowledge about their specific impacts on certain taxa, such as invertebrates and amphibians, particularly in lake ecosystems (Bashinskiy, 2020; Andersen et al., 2023). Furthermore, the socio-ecological aspects of beaver reintroduction and management, including human perceptions and conflicts, are underexplored. Understanding local knowledge and perceptions can help develop adaptive management strategies that balance ecological benefits with human needs (Ulicsni et al., 2020). 10.2 Emerging research areas and methodologies Emerging research areas include the use of advanced monitoring technologies and modeling approaches to study beaver impacts. For instance, continuous hydrological monitoring and high-resolution aerial imagery can provide detailed insights into how beaver dams influence water flow and habitat structure over time (Puttock et al., 2021; Andersen et al., 2023). Additionally, the application of bibliometric analysis to study trends in beaver-related research can help identify emerging themes and guide future studies (Treves and Comino, 2023). Another promising area is the investigation of beaver impacts on climate change mitigation, particularly their role in carbon sequestration and nutrient cycling (Larsen et al., 2021). Moreover, interdisciplinary approaches that integrate ecological, hydrological, and social sciences are crucial for developing comprehensive management strategies. For example, studies that combine ecological data with local knowledge and perceptions can provide a holistic understanding of beaver impacts and inform conflict resolution strategies (Ulicsni et al., 2020). 10.3 Long-term monitoring and impact assessment Long-term monitoring is essential to assess the sustained impacts of beaver activity on ecosystems and to inform adaptive management. Continuous monitoring of hydrological parameters, such as flow regimes and water quality, before and after beaver reintroduction, can provide valuable data on the long-term effects of beaver dams (Puttock et al., 2021). Additionally, long-term studies on biodiversity, including species richness and abundance of various taxa, can help understand the ecological benefits of beaver engineering over time (Nummi et al., 2019; Andersen et al., 2023). It is also important to monitor the socio-economic impacts of beaver reintroduction, including changes in land use, agricultural productivity, and human-wildlife conflicts.
