A world of integrated human-made and natural systems
Successful beaver-human conflict mitigation through flow device installation, tree-protection, trail-cam monitoring, live-trapping and translocation to enable beaver wetland existence, as beaver wetlands represent valuable natural capital necessary for the wellbeing and protection of human health and biological diversity.
Natural capital represents nature provided renewable and non-renewable resources which produce ecosystem goods and services (Van Andel & Aronson, 2012) including but not limited to water quality (temperature buffering, flow regulation, filtration), nutrient cycling, climate regulation, carbon sequestration, habitat, pollination and recreation.

Flooding, tree loss, beaver problems, health or safety concerns? We're happy to discuss your specific problem to determine how we can help and if a Site Assessment is needed.
A Site Assessment (SA) determines the feasibility of installing a flow device at sites that experience beaver flooding. SA's can be assessed remotely for free, but subsequent site visits come at a fee (see services page for cost). Four tools for addressing beaver flooding exist in order of preference: flow devices, dam removal, live trapping, and lethal trapping. Sometimes flow devices may need to be combined with trapping. Dam removal alone is a short-term solution without trapping and/or flow device installation as beavers will quickly rebuild the dam. Furthermore, dam removal can complicate subsequent flow-device installation without trapping as beavers will continue to dam downstream, exacerbating the problem. Trapping alone is not a long-term solution, as emigrant beavers from neighboring areas will likely recolonize. Flow devices offer a cost-effective, co-existence-based, long-term solution that requires minimal maintenance with periodic monitoring.
Water is scarce in our region so landowners who want beaver on their property exist. Live trapping in accordance with local regulatory agency requirements can be a means to remove beaver from an inappropriate site and provide it to the relevant wildlife authority who will then determine release location and timing using best practices. The live healthy beaver(s) are then released to help accelerate ecological and hydrological restoration at appropriate locations with adequate biological and cultural carrying capacity. Live trapping is best done in the early spring (but not too early), and it may be best preceded with a few weeks to months of trail cam monitoring and site visits to guide the effort, if budget allows. Live trapping and flow devices may not always be the most appropriate alternative, for these cases it's best to find a local, ethical, licensed fur trapper who understands sustainable population management.
