Beaver Dams Mean No Love Lost for Canada’s Emblematic Animal

ALGONQUIN PROVINCIAL PARK, Ontario — The beaver could also be considered one of Canada’s official nationwide symbols, as iconic because the maple leaf, however Canadians have a love-hate relationship with the creature, with the emphasis for many extra on the second emotion.

Some communities in Alberta provide bounties on beavers’ tails. A mayor in Quebec has known as for them to be “eradicated.” Fingers of blame continuously level their manner, rightly or wrongly, for freeway washouts, together with some with deadly penalties. Farmers look on with despair as their land vanishes beneath a beaver pond.

For the second time up to now 15 years, Colleen Watson watched this summer season as beavers flooded a 100-acre woodlot within the Atlantic province of New Brunswick that her grandfather, a blacksmith, took as fee from a buyer in the course of the Great Depression.

“I love to see the nature, right? You can watch it do its thing,” Mrs. Watson mentioned in a tone extra of exasperation than anger with the animal. “The hate is what it’s done to my property.”

The massive rodent has performed an outsize function in Canada’s historical past.

The push by Europeans to take management of what would grow to be Canada from its Indigenous folks was pushed largely by a mania for beaver-felt prime hats, a craze that worn out Europe’s inhabitants. For 200 years, one-third of Canada’s present territory was the unique trapping floor of the Hudson’s Bay Company.

After beavers nearly went extinct by the mid-Nineteenth century, fashions shifted and Canada’s fecund beavers rebounded. They can now be discovered, roughly, in all the nation’s wooded areas, and in 1975, the beaver was declared an official image of Canada.

Beaver dams are the supply of the commonest complaints of beaver harm. When they’re first constructed, the ponds flood previously dry land. When a dam collapses — which generally occurs solely after beavers, wonderful builders, abandon their pond — the push of water can wreck rural roads and railways.

But among the issues brought on by beavers are extra uncommon, and people seize native headlines.

This 12 months witnessed quite a few notable episodes: Beavers chomped by a fiber optic cable, slicing off web service to Tumbler Ridge, British Columbia, and a subway station in Toronto was shut down after a misplaced beaver took a tour.

A variety of seemingly beaver-linked offenses are blamed by the authorities on “weather events,” as when a beaver pond is overwhelmed by rain, however typically the police catch them red-handed (a beaver’s ft are webbed, its entrance paws usually are not). In May, the Royal Canadian Mounted Police obtained their beaver in a case involving stolen picket fence posts. (The crime’s location was a reminder that beavers usually are not Canada’s solely cute, however hardly cuddly wild animal: Porcupine Plain, Saskatchewan.)

Figuring out simply how a lot harm beavers trigger annually is troublesome, mentioned Glynnis Hood, a professor of environmental science on the University of Alberta and an unabashed champion of beavers. She was a part of a analysis undertaking that decided that beavers value cities and cities in Alberta a minimum of 3 million Canadian {dollars} a 12 months, however she known as {that a} “very, very low estimate” as a result of many municipalities merely had no concept what they spent on beaver-related repairs.

Professor Hood herself is not any stranger to unwelcome beaver habits. This 12 months, a beaver household hauled away a number of bushes from in entrance of her home.

“But, you know, trees grow back,” she mentioned. “That’s the consequences of living right up against a very natural area.”

While the professor mentioned she held no grudge in opposition to these famously industrious animals, she did have some sympathy for individuals who imagine that “any beaver, regardless of whether it’s causing flooding or cutting trees, is one beaver too many.”

Once beavers arrive in your life, it may be troublesome to dislodge them.

“I’ve talked to different people, and they said that once they’re in your land, it’s very, very hard to get them out,” mentioned Mrs. Watson, who’s now attempting to determine an answer to take away them from her woodlot in New Brunswick.

Trappers are one choice.

Darcy Alkerton has been a licensed trapper in Spencerville, Ontario, for 45 of his 61 years. That expertise, he mentioned, has taught him the worth of taking motion the moment beavers are noticed shifting in.

“It’s just like ants: If you feed them and don’t manage them, they’ll overpopulate,” he mentioned.

Until 1987, Mr. Alkerton’s beaver-management method included dynamiting dams.

One motive he stopped: “You never see an old dynamite man,” he mentioned one other trapper instructed him.

Now, Mr. Alkerton, together with 21 staff, makes use of picks and shovels to dismantle elements of dams to decrease water ranges.

By legislation in Ontario, beavers could be moved no multiple kilometer after a stay trapping. But Mr. Alkerton mentioned that any beaver moved such a comparatively quick distance was unlikely to take the trace and would quickly return.

That means Mr. Alkerton has to typically, with nice reluctance, kill beavers.

“There is some people that say the only good beaver is a dead beaver, and I don’t believe that,” he mentioned.

Beavers do have their ardent defenders, together with those that denounce the default urge to destroy any beaver dam, even those who pose little actual danger. And some proof means that intact beaver dams would possibly really mitigate river flooding.

The dams — the world’s longest of which, in Alberta, measures 2,788 ft, based on Guinness — create ponds that supply each protection and meals. The lodges the place they stay could be entered solely from underwater, deterring most predators. In the autumn, they gnaw down bushes to create a winter meals cache warehoused beneath the ice.

On a distant gravel street utilized by each canoeists and loggers in Algonquin Provincial Park in Ontario, Michael Runtz, the creator of “Dam Builders: The Natural History of Beavers and their Ponds,” disapprovingly identified a dam that had been partly destroyed. He mentioned logging firms come alongside the street every spring and take out any close by dams.

“In most cases, it doesn’t threaten the road,” he mentioned. “But they have this fear that it’s going to wash it out and they’ll need to spend money to repair it.”

After stopping to admire a big birch tree felled by beavers, Mr. Runtz confirmed their work ethic. But he hesitated when requested about their intelligence.

“They have great instinct,” he mentioned. “But they are easily, easily trapped and easily caught by wolves, so, no, they’re not exactly the brightest animal on the street.”

Also, regardless of tens of millions of years of expertise, beavers, to their peril, nonetheless haven’t found out the way to direct the place bushes fall. “There’s been records of beavers being killed by fallen trees,” Mr. Runtz mentioned. “I keep hoping someday to find a skeleton.”

Beavers’ reliance on intuition over intelligence has helped people develop methods that permit for a minimum of a standoff between the 2 species, if not absolute peace.

A big pond in Gatineau Park, a federal wilderness space in Quebec, lies close to a street that doubles as a cross-country ski path within the winter. But it doesn’t flood, due to one thing often called the Beaver Deceiver.

If a dam is demolished or broken, the sound of spilling water swiftly places beaver colonies into restore mode. The Beaver Deceiver — submerged piping that may management the circulate of water — lowers and maintains the depth of a pond with out the telltale trickling.

This deception has helped the park keep away from harm to its roads and buildings with out killing any of its 1,400 or so beavers, mentioned Catherine Verreault, the park’s appearing director.

In Ms. Verreault’s view, Canadians usually underestimate beavers — and their unique attraction to non-Canadians.

During a go to to the park by wilderness-area officers from world wide, the surprising spotlight was a beaver recognizing, which led to the friends spilling off the tour bus for a photograph alternative.

“These were people who have animals that are really impressive: tigers, lions and elephants,” she mentioned. “But they were so excited when the beaver came along, slapping its tail. It was just perfect.”
