Partnering with Beaver in River Restoration: Beaver Analogs, Beaver Coexistence, and More

Course Description
Join Alexa Whipple, Chris Jordan, Emily Fairfax and Colin Thorne at the Mount St Helens Eco Park this Fall for a 3-day Beaver short course! You’ll learn about their natural history, find out how to read beaver signs, tour beaver colonies, discuss recolonization, live trapping, and relocation best practices, and get hands-on experience with: assessing site suitability for beaver reintroduction; designing and installing BDAs (Beaver Dam Analogs) and PALs (Post- Assisted Log Structures), and; using various devices that help beavers and people co-exist. Each day will begin with classroom briefings, but will be predominantly field-based. We will also organize informal evening talks by local experts and ‘beaver watches’ to observe the animals at work.
Instructors: Emily Fairfax, Ph.D., Chris Jordan, Ph.D., Colin Thorne, Ph.D., and Alexa Whipple
Dates: October 7-9, 2025
Location: Eco Park Resort, Toutle, Washington
Pricing: $950


Course objective and anticipated skill transfer
By the end of the workshop, participants will understand beaver’s life histories and activities, their impacts on the riverscape, strategies for relocating ‘nuisance’ beaver, how to design and build BDAs, and options for using devices to help beaver and people co-exist.
Material to be covered
Tentative 3-day short course program:
Day 1 – Beaver Basics – led by Emily. Morning: Intro, overview, objectives, safety briefing. Beaver 101 and Studying Beaver in Practice. Afternoon: Fieldwork (Tour beaver colonies including assessment of site suitability and talk on using eDNA to monitor beaver (colonies and individuals) and beaver-influenced ecosystems. Evening: (Optional) talk by local expert and/or beaver watches.
Day 2 – Mimicking beaver-generated complexity in flows and morphology – led by Chris. Morning: Beaver Dam Analogues (BDAs) and Post-Assisted Log Structures (PALS). Afternoon: hands-on experience in building BDAs and PALs (Site to be confirmed). Evening: (Optional) talk by local expert and/or beaver watches.
Day 3 – Beaver co-existence and relocation techniques, strategies and best-practices – led by Alexa. Morning: beaver relocation strategies and best practices, using beaver deceivers and pond levelers to manage beaver impacts, and practical demonstration of alternative devices for helping beaver and people to co-exist in the same spaces. Afternoon: Beaver live trapping and relocation, including practical demonstration, and methods for assessing site suitability for beaver re-introduction.

Colin Thorne PhD
Colin Thorne is the Emeritus Chair of Physical Geography at the University of Nottingham, UK. He has studied rivers and biogeomorphology in streams ranging from headwater streams to the World’s largest rivers; including work on every continent except Antarctica. His publications are widely read and have been cited >21,000 times during the last 50 years. While primarily an academic performing original research, he has always considered the practical utility of his research and has advised many local and national agencies and governments on river restoration and flood resilience. His research has been recognised through awards by the American Society of Civil Engineers and the Royal Geographical Society. Colin now resides in Vancouver, WA, where advises BPA on restoration of the Columbia River’s tributaries and does consultancy through Wolf Water Resources and BioAnalysts.

Emily Fairfax, PhD
Emily Fairfax is an Assistant Professor of Geography at the University of Minnesota specializing in ecohydrology. Fairfax is also an affiliate faculty member at the St. Anthony Falls Laboratory. Fairfax uses a combination of remote sensing, modeling, and field work to understand how beaver ecosystem engineering can create drought and fire-resistant patches in the landscape under a changing climate. Her research has been featured in National Geographic, BBC, NPR, PBS, Scientific American, the Los Angeles Times, and the New York Times, amongst others.
Fairfax teaches courses in data visualization, environmental data analysis, hydrology, and geomorphology.
When Fairfax says she can talk about beavers all day, she’s not kidding.

Chris Jordan, PhD
Chris Jordan is a Riverscape Scientist with NOAA’s Northwest Fisheries Science Center and a Program Manager for the Mathematical Biology and Systems Monitoring Program. Chris’ passion and work is fostering the science and the community of practice to promote healthy and functional riverscapes for the myriad benefits and services they provide. A co-benefits framework for land and water user communities that also includes cultural and ecological values for conservation and recreation is possible, and is the only long-term durable solution that ensures a legacy of riverscape health.
