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

Category: Flow Device Installed


Here’s a beaver origin story for you. Stop me of you’ve heard this one before.

In the beginning Skip Lisle taught Mike Callahan to install flow devices. Skip later taught Jake Jacobsen of Washington public works, Glynnis Hood of University of Alberta, Amy Cunningham of Wyoming and Sherri Tippie of Colorado. In between all that Skip came to Martinez, saved our beavers and made this story possible.

Meanwhilewhile Glynnis taught her students and did research proving that flow devices work and save money, Sherri taught Jackie Cordry who was working in Colorado Park District at the time. and Amy taught her friends at the wilderness federation in Montana.

At the same time Mike taught Mike Settell of Idaho, Jakob Schokey of Oregon, Ben Dittbrenner then of Washington, and went on to found the beaver institute which teachers many students from many states and four countries every year.

This interview tells you something about how far their efforts have gone.

Earth Day Special: The Beaver Coalition

 

As we honor Earth Day 2021, the theme running through today’s KBOO programming is the impending climate crisis, and its affect on our home planet. And we’ll be introducing you to people and organizations who are working to protect our environment, and all its inhabitants.

On today’s show, we focus on one of those inhabitants, a species of great importance especially here in the Pacific Northwest. I’m referring to Oregon’s official state animal, the beaver.


312 people have signed up for the beaver summit so far. It has made the BWWW newsletter and is going in the Montana Wildlife Federation newsletter soon. I have an interview with Estuary magazine about it tomorrow. That’s kind of amazing. Registrants come from USDA, CDFW, NOAA and FWS. California state parks and National Parks are there. There are even attendees from the out of the country. I’ve been  scanning email addresses with very wide eyes. Noticing one registrant from the power company and another from NPR.

Wow. We’re in it now. The conference that started as Stone Soup is going to feed a lot of people.

I can’t even really believe California will get any smarter but it’s about dam time they did, don’t you think? Meanwhile a township in Massachusetts called New Natick is about to get a whole lot smarter as well.

New Natick Group Revamping Town Trails (And Deceiving Beavers)

Over the past few months, the committee has come up with a list of projects to tackle this spring. The group has received funding for new trailhead signs, trail markings and kiosks at trail heads. Interpretive signs will also be installed near Pickerel Pond to describe beaver habitat and a device installed by the town known as a “beaver deceiver” — it keeps water flowing under dams so the critters don’t flood trails.

The committee also plans to launch a trail steward program: a team of volunteers that would identify and help fix problems on local trails, whether it’s a downed tree or a guerilla BMX bike obstacle. Drenick said the committee may begin looking for volunteers as soon as April.

I assume they’re hiring Mike to do this? He’s about an a  hour and a half away so its not impossible. I’m glad they have decided to do the right thing and  am sure it will reap rewards many times over the cost to install. Good for them and good for those beavers.

Today it has been eight years since my fathers death. My mom is getting her second vaccine shot and I like to think he is making sure she is taken care of once again.


Well you have a happy little Heidi this morning, Yesterday Georgia covered America in blue paint, the beaver summit conference found out Michael Pollock will be the keynote speaker and the schedule of both days fell into place. Let’s celebrate with some fucking great beaver news shall we?

At Asylum Lake Preserve in Kalamazoo, humans work to outsmart beavers — a welcome nuisance

Across Parkview Avenue from Western Michigan University’s college of engineering, a   group of industrious engineers is hard at work in the university’s Asylum Lake Preserve. Their ingenious creations have left some observers in awe. Others cringe at the litter of felled trees the workers already have created around the pristine lake.

But Tom Sauber, WMU Natural Areas Manager, says he’s supportive of the work of the family of beavers who have decided to move in, even as he works to outsmart them and limit the conflict between the animals and people who enjoy the quiet beauty of the preserve.

Oh I can already tell I’m going to LOVE this story, let me just settle in and appreciate it.

But Sauber says the family of beavers on a small bay along the lake’s south shore has left a small footprint — a few trees down, and their lodge hasn’t created any flooding damage, often associated with their dam-building habits.

“They are the most amazing ecosystem engineers,” Sauber says, “and I marvel at their building skills. We need to live in harmony with them and understand that this is their home.”

Lauri Holmes, co-chair of the Asylum Lake Preservation Association, agrees.

She recently walked the Preserve with Bill Schneider, owner of Wildtypes, the company out of Lansing that has been working to remove invasive plant species in the preserve.

“Bill is really an expert about plant ecology, and he was especially interested in the relationship of the downed trees, the work of the beavers, and the eliminating of the invasives that Wildtypes had been doing for so long,” Holmes says. “Bill was very pleased that the beavers have elected to live here. It means that the environment is healthy. He said that we should ‘revere’ them.”

Oh believe me Bill, I do! And now that we’re on the subject, you’re not so bad yourself.

 

“In order to alter their behavior of wanting to build dams, we have placed a beaver deceiver at the culvert that connects Asylum Lake with little Asylum Lake, the area they would most likely pick to build a dam,” Sauber explains.

The rectangular device allows water to easily flow through but its presence at the juncture tricks the beaver into thinking there is already a dam in place, so they refrain from building there.

Okay, well it’s not a rectangle and that’s not how it works but hey. Points for effort. And if it means beavers get to stick around a little longer you have won my vote.

To learn more about these amazing animals, Sauber recommends reading “Eager Beavers Matter” by Ben Goldfarb.

“If we don’t educate ourselves on the beavers we will never understand their rightful place in the environment.”

Oh I agree. Michigan beaver summit soon? Well done Kalamazoo. You have brightened an already translucent day. In fact, I feel a song coming on.


This has been sitting on the shelf a few days waiting for JUST the right time to share it with you. I think the right time is now, and I’m so happy to be the bearer of good news.

Palouse landowner welcomes beavers, and their ecological wizardry, back to her land

Linda Jovanovich is no farmer. She had run a landscaping business for years in Pullman and then worked as an elementary school librarian. In a college geology course she’s become enamored with the natural world.

So, she started planting aspens, willows and other vegetation along the little no-name creek.

Two-and-a-half decades later that work has paid off. Her property is a wildlife oasis among rolling fields of wheat. Piles of tree limbs dot her land, providing shelter for rodents and birds, coyotes and raccoons.

So, when beavers showed up eight years ago, she had mixed emotions.

On one hand, she was thrilled. She knew streams slowed by beaver dams and lodges create better habitat for animals and insects, collect silt and store and cool water, among other things.

On the other, their ponds flooded her little creek and threatened to drown her beloved trees.

So of course Linda called the Lands Council which is something you can do if you live in Spokane, and they live trapped and relocated the beavers. Okay that works once or twice. But the when she called them back a few years later they had different ideas.

This time around, the Lands Council tried a different approach.

“The first question is always, can we keep the beaver here,” Bachman said. “Because usually when you find a place where you have beaver you have beaver there because it’s good beaver habitat.”

So, on Nov. 5, Bachman drove to Jovanovich’s home and started breaking small holes in the beavers’ dam. These breaches, over the course of an hour, dropped the water level about a foot. Then he built a cage out of chicken wire with the help of Ben Goldfarb, a journalist, Lands Council board member and the author of “Eager: The Surprising, Secret Life of Beavers and Why They Matter.”

Now THAT I’d pay to see. Ben in waders! I sure hope they didn’t build that cage out of chicken wire though, because it will never survive being in the water for any amount of time.

From the chicken wire cage, Bachman ran two 4-inch pipes, placed two cinder blocks at the bottom of the cage, dropped the entire thing into the pond and put the pipes through the beaver dam.

Voila, water rushed from the pipes.

In theory, the pipes will siphon enough water through the dam to keep the pond-level manageable. At the same time, the pond won’t drain completely, keeping the entrances to the beaver lodge submerged and the beavers defended from predators.

Well yes, that’s how it works. And if you do it right and DON’T USE CHICKENWIRE it can last for a decade like it did in Martinez. Hurray! Now just watch the wildlife that moves in, Linda!

Although the Lands Council has been working with beavers for a decade, using these types of tools, which are broadly known as flow-mitigation devices, is a new trick and reflects a shifting attitude toward coexistence in Washington.

Although Washington has a history of beaver tolerance, coexistence has relied mostly on keeping beavers and humans apart.

That’s partly because since 2019, the Washington Department of Fish and Wildlife has run a pilot beaver relocation project. Under the pilot, WDFW issues beaver relocation permits. The agency urges landowners to “take measures to tolerate or mitigate beaver activity whenever possible” before they move the creatures.

Well it’s Washington, so good ideas about beavers are nothing new. I’m glad they are getting down to the brass tacks of coexistence though. Because its the right way for things to be going better for everyone involved.

Jovanovich’s little slice of creek cuts its way through the Palouse’s rich and deep topsoil, the deposited effluent of the unimaginable Missoula Floods. While some of the most fertile soil in the world, it’s prone to erosion. In an intact ecosystem, trees and other plants grow alongside these streams, helping anchor the soil.

Beavers offer another complementary solution.

Sediment from their dams will, over time, fill in incised creeks, not to mention trap water. This in turn raises the water table, promotes growth along the stream banks and increases fish habitat, said Bachman.

While small, Jovanovich’s 7-acre experiment shows a possible future for stream restoration throughout Eastern Washington and North Idaho.

And, if nothing else, it provides her yet another chance to commune with the natural world.

“I’ve always wanted to attract birds and wildlife,” she said, adding “We just should find a better way to live with them.”

The reporter was clearly a little bit Ben-fatuated because he goes on to write about Lars beaver experiments and delights when Ben steps in the water to deep for his waders. But excellent. We need all kind of reasons to live with beavers. And there certainly are many to add to the list.

 


Plenty of good beaver news this morning, with this from Vancouver Island. There’s a brand new beaver advocacy group in the world and the teamed up with our friends at FBD to install a flow device. I just checked out their website and was surprised to see my name – not just Worth A Dam or martinez beavers which is more expected.

Well, if you’re going to make a name for yourself, I suppose there are worse ways.

And right out of the gate they installed a pair of outstanding flow devices,

City of Port Alberni learns to coexist with beavers

Port Alberni has become the first beaver-friendly community on Vancouver Island.

The city has partnered with The Fur-Bearers (a non-profit society dedicated to protecting fur-bearing animals) and VanIsle Wetlands (a Port Alberni company that specializes in non-lethal methods of managing beaver activities) to have beaver conflict sites fitted with “flow devices” that will reduce lethal trapping while protecting local infrastructure, wildlife and the greater community.

Lesley Fox, the executive director of the Fur-Bearers, said the non-profit reached out to the city of Port Alberni about a year ago, proposing a sustainable, coexistence-focused solution to beaver conflict sites.

“Most people are surprised to know that beavers are a part of our cities,” she explained. “This is an opportunity for understanding the role of beavers, and the important role they play in keeping the water on land.”

Hurray for the Vancouver Island beavers! It’s wonderful to see good work being done so near by. Let’s meet the new kids on the beaver block, so to speak.

Chris Holtslag, the founder of VanIsle Wetlands, says beaver dams can also protect downstream spawning areas, which helps increase salmon and trout populations.

“You get better fish, bigger fish when you have slow-moving streams,” said Holtslag.

However, dams can also lead to infrastructure damage. A blocked culvert, for example, can cause flooding and damage to nearby roadways. Removing dams and beavers are short-term solutions, as new beavers will return to the sites where beavers were removed. Beavers are triggered by the sound and flow of the water to build a dam, explained Holtslag.

Hi Chris, great to meet you. I’m so glad this work is happening!

Flow devices are a solution that can protect both the animals and the infrastructure, by allowing water to continue moving as designed regardless of damming activity. These devices have now been installed in two locations on Lugrin Creek: one can be found just off of Beaver Creek Road, across the street from the Alberni Co-op, while the other is located on the Kitsuksis Dyke trail.

The two sites were “especially troublesome” with beavers, said Fox. The mouth of the culvert on Beaver Creek Road had been blocked by a four-foot dam. Holtslag installed a culvert protection fence, as well as a pond leveller: a pipe and cage system that helps to manage the height and volume of water near beaver dams. The cage at the end protects the intake from damage.

“It was a lot of work, very muddy,” said Holtslag. “I put a hole in my hip waders in the first five minutes.”

At the other site on the Kitsuksis Dyke trail, Holtslag installed a pond leveller straight through a beaver dam.

 Now that’s a familiar site! And a great look for you, Chris. Beavers will be very happy to cooperate with your efforts.

Fox said she’s not aware of any other municipality on Vancouver Island that has made this commitment to addressing conflict sites, although the Fur-Bearers have worked with other municipalities in the Lower Mainland to install flow devices.

“It’s really taking off in other places in B.C.,” she said. “This is a great success story, not only for Port Alberni, but the Island as a whole. We’ve had a lot of positive feedback from local residents, who are happy to see a more long-term solution,” she added.

Fox says a shift in policies is happening at the municipal level when it comes to wildlife.

“We’re responding to a need, and it’s coming from the municipalities, for long-term, safer ways of managing wildlife conflicts,” she said. “And we hope to see more of it on the Island.”

Beavers are great teachers. They’ll make sure you know right away if anything needs tweaking or changing. Thanks Chris and Leslie for giving the beavers of Vancouver Island a fighting chance. It’s hard work to colonize a place when you first must cross a strait filled with Orcas. They worked hard to get there.

It’s the least you can do.
