As beavers move northwards, and their populations expand in the Arctic, BARIN addresses how changing beaver populations are impacting hydrology, ecosystems, fish and people and their livelihoods. University and government scientists are working in partnership with Inuvialuit organisations and people to coproduce research and develop tools to support ongoing research and monitoring.

Project location

We are working in the Inuvialuit Settlement Region, with particular focus on the Inuvik-Tuk highway and Aklavik, Tuktoyaktuk and Inuvik. This includes studies at the Trail Valley and Hans Creek research watersheds located along the Inuvik-Tuk Highway.

Trail Valley Creek Research Station. This all-season research camp is located 50 km north of Inuvik, NWT along the Inuvik-Tuktoyaktuk Highway. Environment and Climate Change Canada began streamflow measurements at Trail Valley Creek in 1977 and climate measurements in 1999. These stations are still operational. Research observations at TVC began in 1991 and have continued. Photo: Philip Marsh

Summary

As beaver population are increasing well north of the treeline, they are dramatically altering ecosystems. A key question for the Inuvialuit Settlement Region and beyond is the extent, scope and interlinkages between ecological and sociological changes that are occurring as beaver populations increase. Impacts of beavers can cascade down ecological systems, causing major transformations, known as regime shifts. This project will examine and synthesise the interlinkages between beaver occupancy, stream and lake characteristics, impacts on fish populations, and impacts on local communities in collaboration with the Inuvialuit Fish Joint Management Committee. We will examine key features of these ecological regime shifts such as spatial patterns of change, timing of change and drivers of transitions to different alternative stable states in relation to beaver population dynamics. We will then examine the impacts on local communities and their wellbeing. The project will work with Inuvialuit partners and community members to co-create tools and infrastructure usable beyond the life of the project for ongoing Inuit-led research in the Inuvialuit settlement region and beyond to support Inuvialuit self-determination. We thereby aim to support the longer-term monitoring and research required to inform ongoing stewardship under the transformative changes created by beavers.

L’augmentation de la population de castors bien au nord de la limite de la zone arborée entraîne une modification radicale des écosystèmes. Une question clé pour la région désignée des Inuvialuit et au-delà concerne l’étendue, la portée et les liens entre les changements écologiques et sociologiques qui se produisent à mesure que les populations de castors s’accroissent. Les impacts des castors peuvent se répercuter en cascade sur les systèmes écologiques et provoquer des transformations majeures, appelées changements de régime. Dans le cadre de ce projet, nous examinerons et synthétiserons les liens entre la présence des castors, les caractéristiques des cours d’eau et des lacs, les répercussions sur les populations de poissons et les impacts sur les communautés locales, en collaboration avec le Comité mixte de gestion du poisson des Inuvialuit. Nous examinerons les caractéristiques clés de ces changements de régime écologique, comme les schémas spatiaux de changement, le moment du changement et les facteurs de transition vers d’autres états stables, en relation avec la dynamique des populations de castors. Nous examinerons ensuite les impacts sur les communautés locales et leur bien-être. Le projet sera réalisé en collaboration avec des partenaires et des membres de la communauté des Inuvialuit, afin de cocréer des outils et une infrastructure qui pourront être utilisés au-delà de la durée du projet pour permettre la poursuite de la recherche par les Inuits dans la région désignée des Inuvialuit et au-delà, afin de soutenir l’autodétermination des Inuvialuit. Nous visons ainsi à soutenir la surveillance et la recherche à plus long terme nécessaires pour éclairer l’intendance continue dans le cadre des changements transformateurs induits par les castors.

Looking upstream along the main channel of the Trail Valley Creek - this channel has numerous small beaver dams.
Looking upstream along the main channel of the Trail Valley Creek watershed. This channel has numerous small beaver dams. The two lakes – Little Bear and Big Bear Lakes are sites of long term, extensive hydrologic studies. These lakes do not have beaver dams at their outlet. However, a beaver dam was built on a nearby lake during the summer of 2022. These three lakes, and the main channel of TVC, will be used to study the effects of dams on stream hydrology.
