Beaver Translocation & Reintroduction

The North American Beaver (Castor canadensis) innately expands ecosystem water capture and storage. With any species introductions and relocations, there is risk and abundant variables which can impact the outcome. Beavers will alter the landscape, but there is ample scientific research available supporting the conclusion that beaver engineered systems increase species diversity and expand water holding capacity on the landscape. Ecological resiliency in arid ecosystems is dependent upon water capture and storage. To mitigate risks associated with beaver reintroductions, we offer beaver management solution workshops and continued monitoring and site assessments.

***We ask that clients who select beaver reintroductions as a catchment solution commit to five years before pulling the beaver plug. During the five year timeframe we highly recommend that beaver management practices be put into place as well as long-term monitoring to adequately assess the results of reintroduction.

Included in this service:

  • Initial watershed reconnaissance, site selection, and analysis to determine suitability
  • Site setup for beavers (includes temporary shelter creation and initial requirements)
  • Beaver live capture, transport, care and reintroduction to the selected site(s)
  • Field camera setup
  • Piezometer and temperature gauge installations post beaver activity – to monitor changes in temperature and measure groundwater levels
  • Other post assessment and monitoring is available using a combination Proper functioning Condition (PFC) Assessments, Multiple Indicator Monitoring (MIM), and basic water quality data collection (Temperature, clarity, dissolved oxygen, conductance, salinity, N, P, and benthic macroinvertebrates). We provide an extensive report that includes, methods, results, analysis, conclusions and recommendations.
  • Beaver education and management solutions (trainings, workshops, design and implementation of physical solutions)

The images below demonstrate the increased water holding capacity of a stream as a result of beaver activity. Notice the development of sinuosity and floodplain connection that is beginning to develop within the incised channel.

Less than a quarter mile from the beaver activity the stream reach is devoid of water.
