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

Month: March 2019


Sometimes in my travels I come across a beaver article that is confusing, even for me with everything I’ve seen over the years. I can’t decide if its the wisest most progressive policy in all the land, or a monstrous set of lies getting ready to justify some really nasty trapping, or some combination of them both. Well, brace yourself, because if a city like this REALLY exists, we might all have to move.

Busy beavers a challenge for London officials

Workers with the City of London and the Upper Thames River Conservation Authority (UTRCA) are being kept busy these days managing the beaver population. It’s important work if the city is to maintain its infrastructure and prevent flooding.

Now before you start getting confused we’re not talking about THAT london. This is London, Canada which is right across Lake Eerie from Cleveland. The river that flows through the city is called the Thames. It is about 170 miles long.

“I will say that the population of beavers that we’ve seen in London has grown exponentially over the last four or five years,” said Brandon Williamson, land management technician with UTRCA.

But, the city has a beaver protocol to ensure that beavers are “treated in a respectful and consistent manner, balancing the various needs to protect the beaver and [its] habitat; the overall environment; city infrastructure; people and property,” according to a city document detailing the protocol.

Right now, the city and UTRCA workers are aware of about 50 sites where beavers are living in the city.

Now, I’m scratching my head a little at that. I sincerely doubt that public works is close observers of every colony, knowing family size for example like we did. I’m not sure whether their gues-timate comes from seeing fifty lodges along the river? Fifty dams? Or fifty trees that have been chewed? I mean that would be a beaver colony every 3.5 miles and that’s a little hard to believe since they would ALL need to eat.

One way the city is trying to stay ahead of the beavers is to install so called “beaver deceivers.”  “It’s when they’re in our storm water management facilities or ponds in neighbourhood,” said Shawna Chambers, division manager of storm water engineering. 

It’s believed that if the water continues to flow, the beavers will move to a new location.

Um, no. The purpose of installing a flow device isn’t to drive them out like st patrick and the snakes. How did it happen that London is smart enough to install flow devices and still too stupid to know how they work?  I’m not sure whether the reporter is just confused or the entire public works chain of command is like one giant game of telephone and that’s the message that got through.

Looking at that photo is beyond confusing. The fencing looks right, right distance from the pipe and rounded top like Mike Callahan uses. But what’s it function of the fence? There’s no dam visible. And what is that board? Why is the pipe going uphill? Is there some understanding that if the pond gets very, very deep  then water will suddenly flow up hill hit the board, disturb the beavers and make them leave?

Another piece of the protocol is feeding the beavers, although not human food, of course. Instead, fast growing, inexpensive, native species of trees are planted in areas to provide food for the beavers.

“If you plant these trees, like a poplar tree, that’s really quick growing and a low value tree. The hope is the beavers will choose them over sugar maple and black cherry and hickory and some of the more desired trees that we have,” said Williamson.

Having said that, beavers still go for some of those more desired trees. When that is happening, steps are taken to protect the higher value trees by wrapping them in a wire cage, according to officials.

Something about this entire article is fuzzy. Like those cotton candy dreams where everything seems perfect but you find out it’s really NOT.  So an entire city plants trees for beavers to eat but can’t find time to protect the valuable ones until after their chewed? I’m starting to smell a fox in our hen house.

When asked if the city would consider a cull to reduce the beaver population and prevent damage or flooding, that isn’t the plan.

“Ever since the protocol has been enacted in the city we haven’t had to resort to those measures,” said Chambers. “We have definitely not been talking about anything to the extent of killing the beavers.” 

“I think in the future there may be some other ideas that we may have to look at because we can’t always put a flow device or a beaver deceiver in but before a cull is even considered there’s going to be lots of other options that we’ve got,” said Williamson. 

Suddenly I get the feeling that this entire article has been gently leading readers by the hand to this conclusion. We tried our best, they woefully say, installing flow devices and planting low value trees, but there’s just TOO many of them. There’s only one way out. And reasonable people will agree that unless we all want to be drowned in our beds, it’s time to reach for the trap.

Instead of killing the animals, there’s a commitment in London’s beaver protocol to increased public education.

“We need to let people know we’re trying to work with the wildlife and trying to live cohesively with wildlife to make sure that both sides are happy in this,” said Williamson.  “Beavers are known for being creators of wetlands,” said Chambers. “In nature it can be quite nice to set up that blockage and the water is dammed behind it. It creates biodiversity.”

“Education is huge,” he said. “We’ve got people who say [the beavers] are cutting all the trees down so we’ve got to get rid of them. Well that’s their food; that’s their habitat. They’re allowed to be there.”

I haven’t stopped scratching my head through this entire article. Do you have any people shouting “Why the hell is our city LETTING the beavers chop down trees instead of wrapping them?” Any action by beaver loving residents that was big enough to result in THIS policy I would know about. But I don’t. Unless it happened more than 11 years ago when a massive city protest resulted in huge changes, because it’s nothing I covered on this website. And there’s nothing written about it on the internet, I don’t know. Doing a beaver deceiver demonstration at earth day is remarkable and if a city were really committed to coexistence it would be a good idea. But I’m a naturally suspicious person and there are a ton of errors in their thinking. Could this be true?

Is London a beaver city on a hill?


Today we have guests coming associated with the Sequoia River Lands Trust because they want to ask questions about beavers.  They are hoping that hearing the Martinez story will encourage them on next steps. So Jon is making lunch for us and I am trying to be coherent.

Just in case you need a Geography lesson, the headquarters of the Sequoia River Land Trust is in Visalia, which south of Fresno and North of Bakersfield. Here’s their mission statement:

Sequoia Riverlands Trust is a regional nonprofit land trust dedicated to strengthening California’s heartland and the natural and agricultural legacy of the southern Sierra Nevada and San Joaquin Valley. The wealth, productivity and beauty of this land inspire our work to conserve it for future generations.

If the name sounds familiar its because years ago one of the designers of this website, Scott Artis, took a communications job with them and I was one of his references. Scott worked in the medical field and wanted to break into environmental biology, so used Worth A Dam as his credentials for a while – which was great for us, and I assume great for SRLT. Scott himself longed for the Bay Area and eventually moved onto the Audubon Canyon and I believe is working independently now. But beaver paths that cross leave deep tracks, as well you know. I’ll let you know how it all unfolds.

Mean while Sarah’s Beaver-Climate change documentary is on the front page Sunday news in Walla Walla.

Filmmaker finds hope in charismatic tree chompers

Sarah Koenigsberg is used to telling other people’s stories.

The Walla Walla resident has been all over the map in her role as owner of and producer for Tensegrity Productions. In 2013 though, Koenigsberg was ready to devote serious time to her own project, a longer piece that would require the right topic and level of commitment to bring it to fruition.

“Then I just happened upon multiple people in various fields of restoration … all espousing how beaver restoration could be a profound way to come at climate adaptation,” she said.

Beavers? Like the furry creatures who live in the river and build dams?

Yes, beavers.

Nice intro! Of course beavers. It’s always beavers. Around here anyway. Need help saving salmon or removing nitrogen of fixing a deeply incised bank? BEAVERS can do it. Prevent fires, recharge the ground table and save us from climate change? Why the hell not?

“The Beaver Believers” is whimsical — with those big chompers and twitchy noses, beavers look ready for prime-time comedy — but carries the urgency of climate change conversations.

The story revolves around an unlikely cadre of activists who share a common vision of rebuilding the population of the North American beaver, which Koenigsberg calls the “most industrious, ingenious, bucktoothed engineer” in the watersheds of the arid West.

Unlikely? Who are you calling unlikely? I’ll have you know I was voted most likely to save beavers in my graduating class of 83. Or would have been, if there was such a thing in the Reagan years. And honestly, twitchy noses? You are thinking of rabbits. Does this really look twitchy to you?

 

Then the Carlton Complex Fire in the summer of 2014 sparked the opportunity to get really visual. At the time, the Okanogan County inferno was the most massive, recorded wildfire Washington state had experienced, burning more than 250,000 acres.

Her camera could capture the effect of the blaze blasting through beaver restoration areas, to record if the believers’ hypothesis would hold. That example of ecosystem resilience was “kind of gold,” she said, noting that functioning drainage systems are natural firebreaks.

“Water doesn’t burn. It doesn’t take a Ph.D to know that water doesn’t burn.”

Oh no it doesn’t. This is just the right thing to be reminding viewers of. Although preaching to the choir was a phrase probably written specifically for the idea of showing a beaver documentary in Washington state.

“I’m getting flooded with messages from people across North America. They want to try all these things, plant willows, learn about local farms. There’s a whole ripple of ways people are trying to bring it closer to home in what they do.”

I bet she is, I bet she is, because I’m having lunch with strangers from Visalia for goodness sake! And not surprisingly, the premiere is sold out. Could you possibly go to Alabama or North Carolina next?

 


Expert analysis of the Mueller report.


What matters it how far we go?
His scaly friend replied
There is another shore, you know.
Upon the other side.

When I read these credits on this article the other day, I was certain they had made a typo. A quick consultation with our friend the Spokane author reassured me that everything was perfect as it was written. There is, in fact, another Ben who writes nice things about beavers upon the other shore. Well, okay then,

The triumphant return of the British beaver

There is a particularly magical West Country woodland that I know, through which a sunlit stream meanders, braided by a series of neatly dammed pools that hum with life; dragonflies and mayflies, swallows, swifts, kingfishers, amphibians and small fish teem here in numbers rarely seen in Britain. The birdsong is cacophonous. The water’s edge is lined with the fresh growth of willow, hazel and alder, artfully coppiced as if by a skilful gardener. This wood happens to be home to a family of reintroduced beavers.

You see my confusion. “Cacophonous”? “braided?” Sure sounds like the Ben we know writing big flowery big words about beavers. But no, it’s another Ben entirely! A British Ben! (No, not the clock.)

Streams engineered in this way by beavers play a critical role in protecting us from flooding, as well as from seasonal drought. Without beaver dams, winter rainfall brings a torrent of water that rushes downstream, causing flash flooding. That gives way to dry, lifeless gullies in the summer once the water has gone. Beaver dams slow the flow of water, giving nature time to sift it of sediment and impurities, and release it evenly through the year.

The return of beavers to Britain, along with all that they do to bring life into our landscapes, is truly a marvel.

Two continents of Ben’s praising beavers! I’m liking this! Can there be more? I like the idea of being surrounded by Ben-beaver wisdom. No matter what direction you embark you could find a Ben to tell you why beavers matter. Let’s work on the idea of asia-Ben.

In areas where beavers do present a problem, such as in man-made ditches designed to keep low-lying arable land from being flooded, they must be managed, preferably non–lethally. But opposition to the return of beavers mostly arises from misunderstanding. There are worries that migratory fish such as salmon and trout might be unable to make it past beaver dams, which ignores the fact that they co-evolved over millions of years with beavers. And some people object to the ‘mess’ created by beavers along the water’s edge. Considering that the majority of our land is stripped, cultivated, tidied and managed by humans, surely we can we allow nature a bit of free rein along our watercourses.

The return of beavers to Britain, along with all that they do to bring life into our landscapes, is truly a marvel.

I suppose, somewhere in the annals of history, there is an American writer who noticed beaver were reappearing on the landscape in 1912 or 20 and observed how wonderful it was to see them back on the landscape. It’s hard to imagine now, but I sure wish I had been there, to see the streams spark to life again. Of course by the time the beavers were coming back we were already ruining their waterways with unchecked American industry of our own, so I guess for a long time they cancelled each other out.

Still its fun to watch others discover what you already know and love.

And just to make sure you get both your daily-Ben doses, there was a nice interview on the Down to Earth podcast” out of New Mexico yesterday. I think you’ll enjoy this listen to “The little Rodent that Could“. It’s a smart discussion of why beavers matter to an arid state, and the interviewer is both surprised and curious about the right things.


What a difference a week makes. It seems like just seven days ago I was reading in Ted got-it-wrong Williams Angler artiicle about how BAD beavers are for fish. Apparently just 100o miles away they know better.

After a century’s absence, beavers return to Cedar Creek

Skiing into Cedar Creek isn’t easy, but a few Montana Trout Unlimited members willing to brave this year’s deep snow were rewarded with more than pretty scenery.

A few days ago, on her way up the drainage near Superior, Trout Unlimited project manager Tess Scanlan did a bit of a double take as she stared at one of the jumbles of wood she had helped position along the stream.

Where there should have been an undisturbed pillow of white covering the wood, she saw a narrow channel through the snow connecting two areas of open water. It could signal only one thing: beavers.

“We’ve been working for the past 10 years with the Forest Service on restoration up there,” Scanlan said. “Beavers are in that zone, but they’re now back in Cedar Creek for the first time in over a hundred years. It’s a super pleasant surprise.”

A decade ago, Cedar Creek wasn’t healthy enough to support beavers or a thriving population of native fish. A long history of placer mining had degraded the stream and surrounding riparian areas. Streambanks were damaged, some segments of the stream channel had been rerouted, and large woody debris and natural formations within the channel had been removed, according to Lolo National Forest documents.

Beavers can take over from biologists and finish restoring the stream, because beaver dams improve water quality, trap and store carbon — and can help retain groundwater during dry spells. Plus when that groundwater wells up at points downstream, it keeps stream temperatures down, helping native fish that need colder water.

Recognizing the importance of beavers to stream health, states such as Nevada, Utah, Wyoming and Washington are trying to reintroduce beavers into streams that need help.

Fortunately, they moved into Cedar Creek on their own.

AHA! Finally some trout lovers who love beavers too! It’s about time they got some respect around here!  What a fantastic way to recognize their top-notch contribution to streams. Everything’s better with beavers! This is what Sarah Bates from Missoula wrote this morning on the beaver FB management forum

Beavers recolonized a western Montana stream after a restoration project added woody debris and allowed a more dynamic floodplain. Since then, native fish numbers have increased, otters have showed up, and riparian vegetation is thriving. And now the beavers are making the news!

Now this is how it’s supposed to work. Beavers are given the credit they deserve and in return they give us the streams and fish we deserve. Isn’t that wonderful?

We’re trying to provide cold, clean, connected and complex habitat. The complex part comes with all that added wood. But with that, we’re also reconnecting the floodplain because it slows down those high flows in the spring runoff and helps recharge the groundwater,” Scanlan said. “You’re bringing back this natural ecosystem.”

Montana Trout Unlimited will do a little more road and revegetation work this summer, but this may be the last work season, Scanlan said.

“We’ve compared stream sections we restored to reaches where beavers have moved in and they create the same (natural formations),” Scanlan said. “You make it more habitable and they come in.”

I still think folks get this wrong much of the time. They think we cleaned the creek so the beavers come. When in reality the beavers don’t care much whether the water is polluted or clean. They care about willow or aspen and cottonwood. If you give them that, they can fix the pollution for you.

Just give ’em time
