Rethinking the Beaver: Why beavers and humans have to learn to get along
CBC Radio | Posted: April 5, 2019 2:43 PM | Last Updated: April 5, 2019
Four centuries of fur-trade trapping nearly wiped beavers off the North American map. Now they're back, big time, and we're discovering that sharing the landscape with such tenacious ecosystem engineers isn't always easy. We're also learning that there are compelling reasons to try to coexist with this iconic species. Contributor Frances Backhouse explores how two control freaks — humans and beavers — can get along.

Why is it hard to live alongside beavers? Well, I like to say that you've got two control freaks that are trying to compete for the same resources. - Glynnis Hood
In October 2011, Senator Nicole Eaton rose in the Red Chamber to speak about beavers. But rather than praising Canada's national animal, she disparaged Castor canadensis as a "toothy tyrant" and "a dentally defective rat" that should "step aside as a Canadian emblem."
While Eaton's speech prompted many outraged citizens to rally to the beaver's defence, a significant minority agreed with her. That was no surprise to Glynnis Hood, a professor of environmental science at the University of Alberta who has been studying beavers for 20 years. She's found that "people either really love them or they really hate them."
Beavers have a roller-coaster history in North America. Long before humans showed up, they colonized the continent, occupying almost every stream and lake from the Atlantic to the Pacific and from the Rio Grande to the northern treeline.
This ubiquitous animal was culturally significant in a wide range of ways to most of North America's First Peoples and appears in many legends that reflect careful observation of the beaver's vital ecological contributions. These include Blackfoot stories that tell how beavers helped create the world, and how they gave humans the gifts of tobacco and the beaver medicine bundle.
When Europeans arrived in North America, they saw beavers as brown gold to be mined with the greatest possible expedience. By 1900, beavers were gone from most of their historic range and exceedingly rare in the few places where they still hung on. Many observers believed they were headed for oblivion.
But, as we all know, beavers didn't go extinct. Their comeback started in the early 21st century. Spurred on by advocates like Archibald Belaney, better known as Grey Owl, governments started regulating trapping and reintroducing beavers back into their old haunts.
The beaver's rebound has not yet restored the species to its original abundance, but complaints about tree cutting and land flooding keep people like Massachusetts-based beaver management specialist Mike Callahan as busy as the dam-builders themselves. The problem isn't so much the number of beavers around today. It's that we've taken over much of their former domain and forgotten how things looked and functioned when they were present.
Sharing territory with an animal that rivals our ability to shape landscapes and direct water flow challenges our desire to be in control. But the beaver's supporters point to the many benefits this keystone species provides, from habitat creation to water stewardship. They say we need to shift our thinking — to see beavers not as trespassers and troublemakers, but as an integral part of how our hydrological and ecological systems work.
One of the beaver's ardent fans is Pierre Bolduc, who brought in a crew of the buck-toothed engineers to build a pond on his property. "What I want to do," Bolduc says, "is to get people to appreciate how lucky we are here in Canada to have this absolutely fantastic animal."
