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

Month: November 2024


This recent video of Mike Digout in Sascatchewan got my full attention. This beaver is working VERY hard to get this little scrubby weed. clamboring over those boulders has to be difficult with wet webbed feet. And if s/he slips into a crevice that beaver will never get  their heavy body out. It’s so inaccessible and given his poor eyesight he can’t possibly be seeing it from the water.

That weed must smell fantastic!

I do remember faintly with our beavers there were a few rare scrub plants worth taking risks for. Most notably with our first mom beaver. One winter she went crazy for this little nondescript white flower and on election night she actually climbed UP the steep bank towards the county building and came face to face with a vote counter taking a coffee break.

They were both VERY surprised.


I was very excited to see this headline appear yesterday. Bring it on Chicago. I want to learn everything!

Beaver survey aims to show the urban benefits of Chicago’s ‘ecosystem engineers’

Every night for the last few weeks, the wildlife biologist has checked the live feeds of trail cameras she’s installed along stretches of the river’s two branches hoping to spot the largest living rodent in North America, weighing anywhere from 25 to 90 pounds.

Meslar/Chicago Tribune) “I wonder where that little guy was heading,” said Stephen Meyer, who was driving the boat, as he revved the engine and watched the beaver make its way north from across Ping Tom Memorial Park in Chinatown. Beavers are mostly active at night, but as they prepare for winter in the late fall they might be seen during the day as well.

Meyer is a volunteer coordinator at the local nonprofit Urban Rivers, which is funding and lending resources such as the boat to Clark, who has been contracted as an independent researcher for a two-year study in Chicago — the first of its kind to try to understand beaver populations in such an urbanized location.

Hey I wonder if she’s heard about Martinez?

“No studies have been done here and, as far as I have found in the literature, this will be the most urban environment that beavers have been surveyed and studied in,” Clark said. “The only other place was maybe Seattle, but the (human) population of that area was still significantly less than the population density of Chicago.”

Sheesh not so much as a mention! Didn’t you even read Eager?

Other urban areas where beaver populations have been studied include Saskatoon, Saskatchewan, and Flanders in Belgium. But, for the most part, beaver research is done in wild, remote locations with little to no human presence. Her only other sighting was in Yellowstone National Park — “the epitome of nature.”

So now in Chicago, the third most populous U.S. city, Clark has set out to learn: “How much usable space do the beavers even have? And how do we live alongside wildlife?”

Apparently we can manage for a decade. We’ll definitely be talking. I look forward to the Chicago beaver festival!

On the recent outing, Clark was looking for signs of beaver activity such as felled trees or trunks with teeth marks, piles of branches and debris known as lodges on the riverbank, and scent mounds that the animals use to mark their territory.

In a short pit stop before getting to the study survey area, Meyer approached an artificial floating garden — one of many that Urban Rivers is installing along the river to restore native wetland habitats, which provide food and shelter for wildlife, as well as natural spaces for humans.

Scientist Sammie Clark, with Urban Rivers, inspects a possible beaver scent mound on a floating garden built and maintained by Urban Rivers along the South Branch of the Chicago River as Stephen Meyer, an Urban Rivers volunteer coordinator, adjusts a camera, Nov. 20, 2024. (Eileen T. Meslar/Chicago Tribune) This specific island was commissioned from Urban Rivers by the real estate company Prologis right off a South Branch property as part of a commitment to sustainable development by including critical habitat in the still industrialized area. Further up the river, along the North Branch Canal and east of Goose Island, the nonprofit has led a restoration project called the Wild Mile, where floating gardens mimic natural wetland habitat like the ones that might have been found in the city before it was developed.

Beavers were essentially eliminated from Illinois by the early 1900s after decades of unrestricted trapping practices but reintroduced between the late 1920s and early 1950s. They are common throughout the state nowadays. This comeback mirrors the population’s nationwide recovery of 10 to 15 million from as many as 400 million before the arrival of European settlers.

But wetland habitats have been significantly reduced in the country since then — 90% of Illinois’ original wetlands have been destroyed by urban development and agriculture — so restoring these natural habitats is key to sustaining beaver population numbers, experts say.

Urban beavers are a great passion of mine. You  might have come across something of my interest on the internet.

Hmm.

 


Wishing you the Coziest warm Thanksgiving where all your loved ones have just the right place to be. I saw this last night and fell in love. I need a beaver bank den added right away.

I was cheered to see this article but a little worried about Doug being all alone. Has BC not heard about relocating family groups together?

Meet Doug the beaver, the Secwépemc watershed recovery engineer

At the heart of Skeetchestn territory is the Deadman Watershed, a living landscape of roughly 900 sq. km of forest and grassland northwest of Kamloops (Tk’emlups).

“The Deadman Watershed has been absolutely devastated,” says Shaun Freeman, senior wildlife and habitat biologist with Skeetchestn Natural Resource corp. “What we ended up with is a lot of hydrological issues.”

In the early spring, the snowpack melts all at once, with little water retained in the upper watershed due to vegetation loss, he explains. This has knock-on effects for the entire ecosystem

Tsecmenúl̓ecwem-kt (We Repair the Land ) is a project led by Skeetchestn Indian Band to remedy this situation.

They have many partners including Thompson Rivers University, the province and the Secwépemc Fisheries Commission. But the arguably most hardworking collaborator is one you may not expect — an ancient ally in ecological stewardship known in Secwepemctsín as sqlew’uwi and in English as the North American Beaver.

Well now I like how it starts. I got all comfortable this morning thinking I was going to read a delightful yearn about how a bunch of beavers changed a watershed together. Turns out Doug is alone.

To help the land, Skeetchestn’s Tsecmenúl̓ecwem-kt project has successfully populated the upper watershed with one beaver, known as Doug, with the goal to re-introduce more over coming years.

Beavers like Doug have a natural instinct to build dams across flowing water, creating ponds to evade predators. These ponds influence local hydrology, enhancing the habitat for countless other species, including plants, waterfowl, amphibians, invertebrates and of course salmon.

Having ponds and wetlands keeps moisture in the soil and keeps that deciduous component healthy,” which Freeman says is important because those tree species don’t burn to the extent of evergreens. This creates natural fire breaks which can stall or potentially stop a wildfire from moving across the valley.

What’s even more important is slowing down the flow rate to maintain downstream flow into the heat of summer, when low flows block fish passage and can even be fatal.

Okay. So far so good. But I’m starting to get that feeling you get when someone you don’t very much trust says a little nice thing. Like you want them to stop talking before they ruin it.

“We are trying to make sure that the streams are not just a pile of rocks when it comes to August and September because everything, including us, needs water,” Freeman says. “Healthy ecosystems require water which is why we are trying to have the beavers help us do that recovery.”

“In terms of relocating beavers, it’s a little bit more complex than just grabbing them, putting them in the truck and dropping them off,” he says. They must be set up for success.

Since the 2021 Sparks Lake wildfire, there has been good regrowth of deciduous species, including aspen and willow which are important to beavers as food and building material. Three sites with good conditions were selected for possible reintroduction.

But the timing of the beaver capture and release is critical.

“We don’t want to be in a position where we’re capturing beavers that have kits in the lodge,” he says. Which means capturing needs to happen in the late winter or early spring.

They also need time to prepare their infrastructure — the lodge, feed pile and any dams they need to control the water level — in their new habitat. If you put them in too late, the chance of successful colonization is reduced.

Yes that’s all true. So why is Doug alone?

So, the first step was to prepare the holding facility where the beavers will stay between capture and release: the beaver hotel.

In creating a good habitat for Doug the beaver, the Interior Wildlife Rehabilitation Society was very helpful, and the team visited the Summerland beaver hotel to learn how it works and design their own.

The first guest of the Skeetchestn beaver hotel, a female the team named Willow, was not quite what they expected.

“Unfortunately, Willow decided to climb the seven foot chain link fence, as evidenced by the muddy footprints she left behind,” says Freeman, something they didn’t know a beaver could do.

WHAT? The first beaver you stuck in your holding cell was soo miserable to be ripped away from her family that she climbed the 7 foot chain link fence and jumped from that height to crawl away?

This should give you a clue about what a beaver feels about being alone and in your jail.

In contrast the second beaver they caught, a male they named Doug, was more than satisfied with his accommodations.

“He knew the gravy train was coming to him.”

There were a couple of times he was so deeply asleep the team thought, “Oh geez, Doug’s dead!” And they would have to wiggle his cage and tip him out.

Yeah Doug sounds like a real catch. A mover and a shaker. Some beavers are just lazy. Shocking but true.  Remember our 2 older yearlings who never did anything? I used to call them the useless bookends because they looked exactly alike and never helped.

.Skeetchestn is not the only community interested in the positive effect beavers and their dams have on ecosystems. Elsewhere in the province the 10,000 Watersheds Project is building Beaver Dam Analogs, an alternative to natural beaver dams which seek to mimic their effect on hydrology.

While these are an exciting technology, Freeman says they have drawbacks. Humans have to build them and, unless the analog is adopted by beavers, humans are responsible for maintaining them too.

“They are also liable if something goes wrong,” says Freeman. “But you can’t sue a beaver.”

Ha. You can sue the people that put him there.

The beaver colonies in the lower watershed that had been the targets for relocation suffered deaths over the winter. The team was not keen on taking any additional beavers from them at their current population level.

So, Doug was introduced alone to the upper watershed and he seemed to like the location the team selected, suggesting their assumptions about the habitat’s suitability for supporting beaver are very likely correct.

“He went right at it, barely leaving the site we released him from and just started building,” he says. Doug actually built two lodges.

“I think he decided the first one wasn’t up to his specifications, whatever those may be,” he says, but Doug seems much happier with the second.

Next year the team will be sourcing beavers from some of the areas where they are overly abundant.

Because you know how it is. Sometimes there are just too many and you need to spread them around. Just staple them in where ever they’re needed

“Because we do have the ability to host beavers for as long as necessary, we’re able to really start sourcing and looking at some of these other areas which have similar problems in future to and basically become the beaver hub, so to speak, for Secwepemc territory.”

They have already had offers from staff in Tk’emlúps that have some issues with beavers in high numbers. If beavers overpopulate a watershed, they can do damage, he explains.“So, we have a job for them. It may not be in the low part of the drainage, but we definitely have a job for them in the top,” Freeman says.

No. That’s not actually true. Beaver don’t destroy watersheds. They don’t keep breeding until it’s all ruined.

“It’s just a case of shifting from where we have an over abundance, putting them where we don’t have any, then letting them work their magic to help us recreate the hydrology into something that’s going to sustain the whole water table.”


Bob from Georgia reminded me this morning of our historic archive. This was first Published on January 30, 2008 in a post called Why we fight“.

This is a letter from Mike Callahan of Beaver Solutions to Heidi, but we really think it applies to everyone who has supported the beavers:

Dear “Beaverlady”, 😉

Your efforts are Herculean. It is so difficult to promote coexistence with beavers in an urban setting, especially one that is prone to flooding without beavers. Nevertheless, your efforts have given these beavers a fighting chance at survival.

Irregardless of the City’s final decision with the M. beavers I hope you can see that your efforts have had huge positive effects for not only the Martinez beavers, but also for beavers everywhere. Along with others, you personally have raised beaver awareness in the California masses. Not an easy task, and extremely important if our society is to evolve a better culture of coexistence with the animals on this planet.

I thought you should know how impressive your efforts and results have already been, because I know when a person is in the middle of a fight it is hard to see the entire battleground. I’m glad you are involved. Thanks.

All the Best,

Mike
