Because the beaver isn't just an animal; it's an ecosystem!

Month: September 2018



If you are like me you can vividly remember this powerful scene from the long-lost program “Northern Exposure” where Marilyn explains to Ed that the wisest amoung us can’t always tell if something is good or bad news. I know the clip isn’t great quality, but be patient and think of it like delicate pot shards recovered at that most sacred archeological site in Turkey, Göbekli Tepe. Not pretty, but profoundly worth your time and careful consideration. Today especially because we are going to talk about a beaver news story that leaves me exactly as to undecided whether it’s horrific or enlightened.

Merry Lea Students Forage on Canoe Trip Along Elkhart River

Joel Pontius

Every year in September, I lead students from Goshen College’s Sustainability Leadership Semester on an eight-day canoe trip from the headwaters of the Elkhart River at Merry Lea Environmental Learning Center to Lake Michigan. Along the river we forage wild food and meet with local entrepreneurs, pastors, artists, community developers, restaurateurs, professors, NGO professionals, residents, farmers and political leaders. In these interactions we explore many ways to contribute to resilience in our places and sustainable futures for our communities. Michiana’s local foods community is a main thread in our conversations.

Our paddles churn the surface of the Elkhart River as our canoes glide around a sweeping bend. The world is glowing green beneath the shade of the broad-leafed sycamore canopy on this crisp afternoon. Cardinal flowers bow to the river, red from the dark, exposed soil. A great blue heron spooks downstream as a train rumbles by on the riverside rail. Soon we see fluorescent orange and yellow in the crook of a two-trunked wild cherry tree. As we float closer, we confirm that what we’re seeing is an edible mushroom called chicken of the woods.

So far so good, right? A nature-focused outdoorsy college leads a group of students on a canoe journey down a river in Indiana hoping to teach them what they will need about sustainability to be tomorrows leaders.

But like everything in life, the story gets more complicated.

I receive a call from a friend who works for the county ditch and drain commission removing beavers from agricultural ditches to keep water levels down for row crop farmers.
“Hey, I have a beaver if you still want him.”
“Yes! Can you make it to the feast?”
“I’ve been trapping for 30 years and I’ve always wanted to try the tail. Read about it in Lewis and Clark’s journals. I’ll be there.”

Oh. So we’re going to celebrate this lovely and sustainable journey by eating an ecosystem engineer? I’m thinking this is suddenly less idyllic.

If it were up to me, the beavers would stay alive and well, creating rich wetlands as they do. However, since the trapped animals are usually left for coyotes, I feel OK about gleaning this food as a learning experience.

Now I’m just confused. Obviously you know why beavers matter, and that’s good. I assume you’ll talk with your students about that. And I kind of agree with you that its better not to waste what was killed. But I’m still saying EW.

We return to Merry Lea Environmental Learning Center, where the students live in community for the rest of the semester at Rieth Village, residential cottages that model environmentally conscious design.

We process the beaver together, first removing his beautiful skin. For some of the students, it is the first time they have processed an animal they would later eat. Beneath the skin is scarlet muscle. We remove the tenderloins along the inside and outside of the spine, the front and back legs and the tail.

The next evening, the group transforms the meat into tikka masala; salsa verde saute; traditional roast with carrots, onions and potatoes; charcoal-grilled tail; and teriyaki tenderloin.

This meaningful, delicious meal inspires lively conversation around the table. We wonder what other sources of sustenance and significance might surround us in everyday places we have yet to discover. As we eat, we recount the gifts that this journey has given and savor Michiana’s original flavors.

Sigh.

You can understand now I bet why I chose Marilyn’s wise tale to accompany this post. There is no way to decide whether this academic exercise is wise or barbaric. If the author knows how valuable beavers are to wetlands then why is he friends with a trapper anyway? And what would happen if they used all that student energy to install a flow device instead so that the beaver could stick around and create better conditions and biodiversity instead of being dinner?

This is a sustainability course right? You know beavers can help with that don’t you?

I remain torn about this story. Joel Pontius clearly believes in working with nature in a sustainable way when it’s at all possible. He wants his students to learn about nature, not just use it and remove it. He’s not happy the beaver was trapped. but he is happy his students can learn from the experience. And to be honest, we’re talking Indiana, for goodness sake, so we’re grading on a curve.

Usually by the end of an article I know how I feel about the subject, and certainly how I want my readers to feel. Not this time. There is only one reasonable answer I can think of.

Joel needs a copy of Eager.


Now that was fun. Nature-savvy, interested and diverse gathering. Every single person wrote down the name of Ben’s book, and one woman said she wanted to come help at the beaver festival. One of the attendees was a long time reader of this website (JoEllen) who was one of our first followers. Everyone was very enthusiastic about the presentation, (even Jon who has definitely heard it all before.)

If I was preaching to the choir, it was the very best kind of choir,

Now I can rest on my beaver laurels until spring when I present to Audubon. That gives me lots of time to focus on the grants and applications which are due in winter. Ahem.

In the meantime I heard from BYU radio yesterday that our beaver interview will be coming the week of the 17th when their new program launches. I’ll keep you posted.

This came up yesterday at my talk, and because of Ben’s great book I was able to explain there was more than wolves needed for recovery.

Yellowstone’s wolves are back, but they haven’t restored the park’s ecosystem. Here’s why.

YELLOWSTONE NATIONAL PARK, Wyoming – Yellowstone’s wolves are back, helping revive parts of the ecosystem that changed drastically when this top-of-the-food-chain predator was killed off nearly a century ago. But Yellowstone is still not 100% back to normal – and it may never be.

You put the predator back, that’s great, but conditions have changed so much in the intervening decades that putting the predator back is not enough to restore the ecosystem,” said Tom Hobbs, a Colorado State University ecology professor. “There’s not a quick fix for mistakes like exterminating apex predators.”

It’s a sign of both the promise – and the limitations – of a multi-decade wildlife recovery effort. The reintroduction of the wolf nearly 25 years ago to the country’s first national park has brought change: Overpopulated elk herds have thinned, allowing some willow and aspen groves to return and thereby creating better habitat for songbirds and beavers. 

One of the questions raised in the discussion afterwards was whether all animals matter equally, or whether some animals mattered more than others. Being a regular reader of this site, I’m sure you can guess where I came down in that argument.

Today, nearly 25 years after wolves were reintroduced into the park, the top predators have helped parts of the ecosystem bounce back. They’ve significantly reduced elk herds, opening the door for willow, aspen, beaver and songbird populations to recover. But the wolves haven’t been a silver bullet for the ecosystem as a whole. 

“This idea that wolves have caused rapid and widespread restoration of the ecosystem is just bunk,” Hobbs said. “It’s just absolutely a fairytale.” 

 


Okay, I’ve checked all the website places I can think of to see if they’re fixed.

Everything I can think of appears to be working, so if you notice something that’s not let me know. Maybe walk around and kick the tires a bit to check, will you? In the mean time we have 2 fun news stories to cover.

Proposed Beaver Holding Facility In Millville, Utah on Wild About Utah

Nice to think of the big beaver mobile they want to put together. Traveling around the state picking up unwanted beavers and putting them in just the right home.

I’m sure it won’t be anything like this, right?

Time for a Toyota. No really! This story is dated 2014 but for some reason it came up again yesterday,

Video: Leave it to Beaver

Sometimes it’s best to let nature take its course.

That’s what Toyota Motor Manufacturing Mississippi environmental specialist Sean McCarthy learned when he and other team members tried to stifle the SimCity tendencies of some resourceful rodents.

During construction of the plant, two retention ponds were established. The ponds are designed to capture and hold storm water runoff, allowing any suspended solids to settle. Water discharge from the pond is regulated with an 11-foot sluice gate and seven-foot concrete wall just beyond the gate. When the gate is raised, the water flows out through three slots in the wall.

Except when beavers dam it.

“They packed the flow slots with trees and mud. It was almost like concrete,” says McCarthy. “We’d be down there once or twice a week and they’d be right back the next week.”

After battling the beavers for six months, the team packed it in by the fall of 2012. And the water stayed.

“It never empties,” McCarthy says. “Even in July and August there’s one to two feet of water. But there isn’t a risk of flooding since water still discharges when it reaches the top of the wall.”

The resulting lake brought other critters. Ducks, as well as fish and other species, now call it home.

Wonderful! Oh-what-a-feeling! Here’s the video they released at the time, unfortunately without any beavers. But nice to see.


So close and yet so far. Yesterday’s magically returned website didn’t disappear into thin air like I worried it would. But it did eventually grow a crippling handicap that I’ll still have to wrestle with today.

If you want to see what it is, try clicking on any “Page” in the drop down menus.

The problem with inheriting a large website of patches is that fixing one part often breaks the other part! I’m sure we’ll get there. It will just require another robust dose of snappy hold music.

But enough shop-talk, lets go to Oregon and talk about BDA’s.

Mimicking nature’s dam builders

Now, in an about-face that bodes well for beavers, stream restoration professionals are turning to small wooden impoundments as a way to improve fish habitat and riparian areas across the West. Made of pounded posts and woven willow whips, these beaver dam analogs are considerably cheaper than other restoration techniques.

Even if BDAs don’t attract beavers to an area, they mimic the action of natural beaver dams — slowing stream flow, improving groundwater connectivity to the surrounding area and building up sediment to improve riparian areas. Juvenile fish can swim through gaps in BDAs, and the minimum fish-jumping height for older fish can be achieved by installing multiple BDAs.

Beaver dam analogs can also help reduce stream water temperature, according to Stephen Bennett, an adjunct professor in watershed sciences at Utah State University. BDAs can increase groundwater connectivity through annual spring flooding and by the hydraulic action of the standing water behind the dams.

Hey! I got an idea about bring back beaver benefits. Just stop killing them! How’s that for a novel idea?

Getting the word out on beaver dam analogs was the goal of a workshop held in Grant County July 24-26. Thirty-five stream restoration professionals attended talks at Grant County Regional Airport and field trips to Murderers Creek, Camp Creek and Bear Creek in the Malheur National Forest.

Attendees included people from watershed councils, soil and water conservation districts, federal and state agencies, the Confederated Tribes of Warm Springs and private contractors.

The purpose of the workshop was not just instructing people on how to build beaver dam analogs or persuading them to use the technique, but also to release new information on what’s been accomplished, said Elise Delgado, project manager for the South Fork John Day Watershed Council.

“Not everyone will leave a believer,” she said.

The workshop was sponsored by the John Day Basin Partnership, which represents groups from Prairie City to the Columbia River. Herb Winters, a project manager at the Gilliam Soil and Water Conservation District, sits on the partnership’s steering committee.

Well gosh. If you can get people excited about beaver dams by letting them build them themselves I guess its a good thing. But you do know beavers have their own ideas, right? They might happily use that BDA and then add three more upstream when you didn’t plan to have a beaver dam at all.  You know how it is when you bring in a designer. They always have their own plans for the space.

At least Nick has the right idea.

Nick Bouwes, a professor at the College of Natural Resources at Utah State University, advised workshop members to be efficient in how they build BDAs because a project might require a lot of them. He said he prefers a messy one, the messier the better — if a post goes in crooked because of rocks, let it be, he said.

Bouwes was a leader in the largest beaver dam analog project in the United States, on Bridge Creek near Mitchell, where a powerful stream had gouged a 6- to 10-foot-deep incision. About 2.5 miles was treated to improve habitat for steelhead starting in 2005.

Bouwes and his team built 121 BDAs from 2009 to 2012. By 2013, beavers had fortified 60 of the BDAs and built 115 new dams. The stream bed gradually filled with sediment and rose back to the top of the trench, and the submerged area tripled.

Monitoring showed Bridge Creek produced nearly three times as much fish as a nearby control stream, and water-temperature spiking eased. The results made Bridge Creek the poster child for BDA projects, drawing international attention and documentary filmmakers.

As it happens I’ll be using Nick’s video tomorrow in my presentation at Sulpher Creek Nature center, which makes it a very good time to re-share.


If this is a gift from the gods I’m just going to take it. Let’s all pretend that the last five days never happened. I spent yesterday trying to restore to a good place and things got steadily worse from there. Maybe this is the eye of the storm. Whatever it is I’m talking it.

Ben and Beavers were on Slate yesterday. And what a glorious article it was.

The Beaver Should Be America’s National Mammal

I’m here to convince you that the beaver should be America’s national mammal.

Yet despite the lighthearted chapter titles—“California Streaming,” “Realm of the Dammed”—Goldfarb’s book is more than a peaceful meditation on the aqua-hobbit folksiness of beavers. Goldfarb wants to show us what beavers did for us once and what they could do for us now. Indeed, his case for the beaver’s importance to America’s past, present, and future is so strong that his book’s publication is the perfect opportunity for America’s beaver lovers to stand up and let their call echo from pond to shining pond: The humble beaver should be our national mammal.

Beavers and their dams altered not just our continent, but the lives and the evolutionary paths of a veritable Noah’s Ark of North America’s creatures. Indeed, the beaver is perhaps the best example of a keystone species—that is, one on which so many others depend. Songbirds, snow geese, otters, herons, pelicans, snakes, mink, raccoon, northern leopard frogs, sawflies, and trumpeter swans, to start. Even salmon, perhaps the last species you’d expect to benefit from nature’s most famous dam builders, owe a debt to beavers (Goldfarb quoted a bumper sticker: “Beavers taught salmon to jump”). Long before Goldfarb describes the beaver’s teeth as “evolution’s most consequential dental sculptors,” he should have you convinced.

Go read the whole thing. It’s wonderful. And it’s wonderful to be back even if its temporary. A bagpipe just started playing in front of my house and I’m going to take it as a sign of good things to come. You might want to update your bookmark for this site because things keep evolving.

Of course you have it bookmarked. Right?
