Quebec Has A Sprawling Water Labyrinth With Over 6 km Of Canals For You To Explore

Tis the season to get lost in corn. As summer comes to an end and harvest season approaches, fields across Quebec have been carved up for your enjoyment. Several corn mazes have already popped up across the province. But Éco-Odyssée in Wakefield breaks the mold.

There, you can embark on a journey through a sprawling water labyrinth, wandering between marsh and forest.

The maze is actually inspired by the beaver.

“The concept of the water maze came to” founder and beaver specialist Michel Leclair “from the beavers that he worked alongside for 35 years,” the Éco-Odyssée website explains.

“The beaver, upon settling in a habitat, digs a network of underwater canals that are similar to a labyrinth. This network allows it to move around throughout the entire year in order to find food and wood to build dams.”

This looks entirely delightful. The only sentence that confuses me is “beavers dig a series of Underwater canals“.. Underwater? Were you expecting viaducts instead?

Michel LeClaire has been working with beavers since Reagan was president. Both Mike Callahan and Skip Lisle traveled to Canada once upon a time to learn from him. I do not think every single one of his ideas holds true today but he is page one on the story of human adaptions for coexistence.

His latest invention looks absolutely magical. So very much better than a corn maze.


I am not always excited about stories where people make BDAS and pat themselves on the back for acting like beavers after killing all the real ones. But this story gets it right. Enjoy!

Beavers do it best. Humans recreate the animal’s engineering to restore a waterway in Sweetwater County

If you’re too busy to listen, here’s my favorite part:

Lush, green vegetation is surrounding the creek. There’s large pools of water. Baby ducks swimming. Fish darting.

“We built a small beaver dam and that was probably a foot or so,” Walrath said as he pointed it out. “Then the beavers have built a four to five foot dam, kind of on top, and now it’s nearly up to grade of where the stream used to be historically.”

Nick Walrath stands in the oasis-like part of the project. This is where they built the first imitation beaver dams and have had success in vegetation growth, stream restoration and beavers moving back in.

That’s the vision: Build the man-made dams. Restore the waterway’s health. Have the beavers take over. It’s a cycle Walrath thinks could play out over the next decade or so.

As long as you promise to let them make whatever changes to your vision they see fit.

 


These photos were shared by Peter Pappas in Vermont yesterday and then re-posted  on the New England Wildlife page. He had this to say about them:

Vermont. Beavers hard at work. Changing water levels encouraged beavers to do their chewing along length of fallen log I believe:

or the

For the record, we’ve talked about it and think he might be right. The differe t heights or “Stairs” might be because of water level changes. We have watched young kits practice chewing by all gnawing on a different part of the trunk at once in the water, bit this seems different.

Let me just take this moment to exclaim how MUCH I love beavers.

 


Beaver dam analogs tend to be more popular than beaver themselves but I guess that’s okay because after people get the grants and volunteers to install them and they wash out or need repairs and have to be repaired folks start asking “How do we make it last” or “How do we make it look like that” or “Who can we get to make repairs this time?” and there is pretty much only one answer to those questions.

Beaver Dams

Beaver dam analogs–catching on in Idaho. -Landowners and conservation professionals are excited about a new type of woody structure that mimics beaver dams. The benefits are similar – they store water, slow down runoff in streams, and enhance fish and wildlife habitat. They’re called Beaver Dam Analogs or BDA’s for short. Bruneau Rancher Chris Black worked together with a number of conservation professionals to install some BDA’s on his private land on Hurry Up Creek, a tributary of Deep Creek.

“I’ve wanted to get beaver in here for years but it is an ephemeral stream,” Black says. “There’s enough willows to make good food for them and everything, but there isn’t enough water for them to stay.” They’ve put in about 10 structures so far, and more are planned in the future.

Hey I’ve got a crazy idea Mr. Black. Maybe if the stream had beavers in it it wouldn’t BE ephemeral. Did you ever think of that?

“It just benefits a whole host of wildlife species and that’s why Fish and Game is really interested in this,” says Chris Yarbrough, habitat biologist for the Idaho Department of Fish and Game. “It’s a low-cost way to get a lot of bang for your conservation buck.” The Life on the Range crew visited two very different projects on opposite sides of Idaho to learn why BDAs were installed, how they were built, and what benefits may occur.”

Maybe the word ephemeral itself is just a fancy way of saying “A stream that isn’t maintained by beavers yet.”

Did you ever think of that?


One last thought,

Many sympathies to Mr. Jimmy Carter this morning who slept alone for the first time in 77 years last night. When I think of Rosalynn’s death I remember the Methodist words of John Wesley.

Do all the good you can, by all the means you can, in all the ways you can, in all the places you can, at all the times you can, to all the people you can, as long as ever you can.


The High Desert Museum in Oregon is one of the most respected museums in the world. It was my father’s favorite and has featured some truly breathtaking beaver exhibits including the interactive grapahic featured in the margin of this page. Once they even asked to use our ecosystem poster in a beaver exhibit.

And now they have this:

Baby beaver from John Day finds home at High Desert Museum

The High Desert Museum recently welcomed a new animal who happens to be an expert engineer, a keystone ecosystem species and the largest rodent in North America.

A baby beaver, called a kit, arrived at the Museum in May. Found in John Day alone in a parking lot, people had searched the area for her family but failed. The kit was then placed into the care of Museum wildlife staff by the Oregon Department of Fish and Wildlife.

Veterinarians estimated at the time that the animal was only a few weeks old. The beaver was very weak and dehydrated, weighing just 1.4 pounds. Wildlife staff spent the next several months working to formulate an appropriate diet and nurse the kit back to health.

“The Museum’s wildlife team was tireless in researching appropriate diet options and providing around-the-clock care,” says Museum Executive Director Dana Whitelaw, Ph.D. “Their dedication to providing the best care is exceptional.”

It took most of the summer for the beaver’s condition to improve, but the baby slowly began to gain weight and strength.

Six months later, the beaver is healthy and growing, now at almost 17 pounds. Staff have built a behind-the-scenes space to meet a beaver’s needs, complete with a pool for swimming. The kit eats a species-appropriate diet of native riparian browse such as willow, aspen and cottonwood, supplemented with vegetables and formulated zoological diets to ensure proper nutrition.

The plan is that when ready, the beaver will become an ambassador for her species by appearing in talks at the Museum that educate visitors about the High Desert landscape.

Just to be clear I HATE when orphans are raised in captivity to be ambassadors but of all the places to be kept on display this is probably the creme of the crop. And who knows, maybe he’ll get a companion one day.

The beaver is doing well and learning behaviors that assist with her care,” says Curator of Wildlife Jon Nelson. “She is learning target training, how to sit on a scale to be weighed and to present her feet for voluntary inspections and nail trims. She also enjoys time playing in the Museum’s stream after hours.”

The beaver is believed to be female. It’s challenging to conclusively identify male or female beavers.

The opportunity to name the beaver was auctioned at the 2023 High Desert Rendezvous. The winning bidder has yet to select a name, which must be appropriate for the Museum and connected to the High Desert.

An estimated 60 million to 400 million beavers once lived in North America, creating wetlands and ponds. The dams built by these “ecosystem engineers” slow streamflow, raise the water table and reduce downstream flooding and erosion. Beavers also help birds, fish and other wildlife and native plants to thrive by creating habitat.

Beaver populations dropped dramatically in the last two centuries with demand for beaver pelts for clothing, most notably hats, in the mid-19th century. Their dam-building activities also at times prompt people to consider them a pest on their properties.

Today in the West, restoration of the beaver is underway and humans in some areas are mimicking its dam-building behavior in order to restore healthy High Desert riparian areas.

“The history of beavers in the High Desert is a profound one,” Whitelaw says. “We hope to be able to share the new beaver at the Museum with visitors soon to help tell the meaningful stories about the role these animals have to play in healthy ecosystems.”

The Museum cares for more than 120 animals, from otters to raptors. Many of the animals are nonreleasable, either due to injuries or because they became too familiar with humans. At the Museum, they serve as ambassadors that educate visitors about the conservation of High Desert species and landscapes.

I’m sure she’ll be called rattle snake or Justin soon. But remember, two years ago the museum dd the best exhibit ever for beavers and the difference they make so take heart little one, at least your among friends.
