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

Canada recently amused itself with this headline, nice to see they haven’t lost their sense of beaver humor.

Canadian Dam Association releases report on the amount of work done by uncertified beavers

– A shocking centuries-long report has been released by the Canadian Regulation on the amount of work done on the nation’s dams by uncertified labourers.

The report details these dams’ failures on levels of structural integrity, engineering, and permit-gathering. However the report went on to note the one positive of the reprehensible workmanship, mainly in the incredible amount of adorable cuteness displayed.

“These dams do not meet our standards, they don’t meet ANY standards, frankly. They don’t even generate ,” said an inspector.

Perhaps most concerning, almost every instance of the dams investigated found that none of these beavers have been financially compensated in any shape or form.

“How do you expect workers on a dam to take pride in their labour if they aren’t even paid for their work?

Yes yes yes, and beaver dams are GOOD for fish and the environment. You really can’t hope to compete. And you shouldn’t try.

“This is a slap in the face to all of our hard-working and driven beavers who go through the proper channels to prepare for work in the dam industry.”

The report is in conjunction with a similar damning study done by The Forest Professional Regulators of Canada on the amount of done by uncertified beavers as well.

Ohh don’t get me started on the list of things that beavers can do better than you. Sheesh!

Rusty had a lovely beaver encounter last night, but couldn’t get close enough with the dog to take the photos of his dreams. Pretty sweet work though…Isn’t it wonderul to see kits using their tails for balance? They look so proud to be a beaver.

History has some pretty remarkable stories to tell us And whenever I spend time in my parents Sierra home it seems to leap out at us. I think last time I mentioned learning for the first time about the great flood in California. This time its a few things that I thought you’d appreciate.

Bronze Age beaver fur revealed by coastal erosion in cliffs in Yorkshire

After a walk across a field the path descends to the beach via a gap to an area called Skipsea Withow. For years Skipsea Withow has attracted archaeologists and geologists as more of what was once part of an ancient mere or shallow lake has become exposed by coastal erosion.

Numerous timbers can be seen studded into the cliff face and remarkably 

well-preserved chunks of wood fall out of peat deposits onto the sand, as the sea continues to make inroads.

A dig in 1993 by the Central Archaeological Service revealed ash timbers with gnawmarks which were believed to have been part of a beaver dam, Beavers vanished from Yorkshire in the 16th century, hunted to extinction by the early 1500s for their fur, meat and scent glands.

My my my, If there’s one kind of archeological tale I enjoy reading it’s the kind where folks find paleo beaver dams where they might have never expected, But wait, it gets better.

Three years ago local historian Sheila Cadman made an amazing discovery after taking a walk on the beach – and coming across a football-sized clump of fur sticking out of the cliffs.

‘When I saw the hair I wasn’t sure what animal it was from,” said Sheila, who in 2013 had discovered bones of two Mesolithic (10,000BC to 8,000BC) deer on clay that would have once been the bottom of the lake.

“It could have been anything, a horse, from cattle or a dog. It was very black and very soft.

“The tide was coming in so I just got it out with my hands and put it in a polythene bag and bought it home

“The following day I returned and measured the distance from the base of the peat to where I was able to extract the hair and it was 2ft 6ins. It was obvious that it was ancient.”

She gave some to experts at Hull University and Sheffield University and later learned that it had been analysed and found to be Bronze Age beaver fur – meaning it dated from around 2500BC until 800 BC.

Imagine finding beaver fur from the Bronze Age!!! That’s got to be one to tell the grandchildren about. There really isn’t a photo of the fur or I would show you, but go read the whole article to see how it all fits together.

And on a personal history note, yesterday we came across the memoirs if my paternal grandfather. He was born in Fairfield and grew up in Suisun, the son of an immigrant from the Azores who never learned to read or speak English. He was the 4th of 10 children, imagine that.His father died of the Spanish flu in 1918 at 51. Which is remarkable in itself. But what really got my attention was his accounts of childhood where he said the kids learned to swim in the swimming hole in Suisun by cutting TULES to place under to place under their arms and using them to aid in floating while they dog paddled.

Imagine that! The original water wings!

He graduated from one of the only high schools in the area, so students from far away had to ride horses or buggies to school. There was even a big barn at the school to house them all day. In  his early teens he tried trapping. This is what really got my attention, He had no look with raccoon but did manage to trap a mink somewhere he called the “BEAVER CUT”. (!!!)

What’s a beaver cut? 

There are no footnotes and he is long passed so we cannot ask him. But remember, this is around 1914. I believe during the brief period that the nearly exterminated beaver population was protected in the state. Does cut mean a chewed tree? Possible, but it’s hard to imagine too many trees were in the Suisun marsh. Then or now,  Maybe cut is a typo and he actually meant beaver HUT: We can never know. All we do know is that there were beavers in Suisun in 1914. And that my grandfather trapped a mink.

Whose fur he was able to sell in Chico.


There is just about no bedtime story I like better than someone coming upon a beaver pond and cherishing every single drop of water it reserves, while revealing in the wildlife it harbors. And if that story is set against some surly backdrop of a place that doesn’t love beavers and a strong woman who has pledged to save them no matter what,  well  that’s even better.

Sacred Surprise

May 25 was one heck of a day. I got out early because it was going to be hot. I wanted to see what was going on down Dean’s Fork. As I trotted along, I heard the twanging “glunk!” of green frogs. I hadn’t heard that down there for several years, not since someone who shall remain nameless took out the beaver dam with a backhoe and killed the beavers who’d made a watery paradise there. Illegally, I’d add. Trespassing, and acting against the express wishes of the landowner, who wants the beavers left alone. Murdered the beavers, destroyed their home and the homes of countless other aquatic creatures, just because he could get away with it. They weren’t hurting a thing in the world there. 

Cautiously, I moved forward, calling Curtis to me. And I saw…water. Lots of water. THE BEAVERS ARE BACK!!!

This is the fullest I’ve ever seen it, with the most magnificent sweeping curve of a dam. These photos can’t really capture the scale of it. It’s BIG. big big big.
 
Oh how excitedly  I share your excitement. Although I might correct that they’re not so much back as replaced – which means that whoever rented that backhoe the first time should be reminded that getting rid of beavers is a temporary soluion at best, and regarding the fish, wildlife and birds it impacts, a very expensive one.

 

I was so glad to see a pond where there had been an overgrown mudflat, I wept. And my next, immediate thought was, “I have to stop him from killing them again.”
 
It was a drumbeat in myth pond on the e head. How to stop him? 
 
Suffice it to say that I’ve been working on it, through carefully placed conversations with key witnesses, through the best channels I have. Tracking down the involved parties, hearing their stories. I’ve been busy, working with dogged determination and a cruel and insensate devil breathing down my neck.

 

Been there done that as they say! We can help you think of solutions. Given the pandemic it might be hard to get a bunch of kindergartners in beaver tails lined up at the pond on the evening news, but we can be creative. It sounds like you know who ripped it out the last time. It’s time top sit down with him directly and find out what he’s worried about. Given that he used a backhoe on someone else land I’m going to guess he owned one and didn’t rent, so maybe a downstream farmer who was worried about the dam ripping out? Or objected  to his stream being reduced to a trickle? Take a neutral respected party, some old timer who can be in between, keep your voice calm and come armed with solutions, Flow device, dam reinforcement, tree wrapping. Whatever is needed,

And I would say add a little pressure from the outside. An article from the local outdoor columnist. A high school teacher who’s willing to have her students do water sample testing in the fall, A local university who can have a grad student analyze new species in the area. An adopt a beaver campaign where children send photos of beaver drawings to the local council. A trail cam that can document all the changes at the pond.


With the great joy that this beaver pond brings me comes a great responsibility to try my best to keep the furry architects safe. I cannot bear the thought that they’d be shot again and their beautiful creation ruined. This incredible pond! It’s alive with fish and frogs (four species were calling as I made these photos) and turtles and green and great blue herons and belted kingfishers and red-shouldered hawks and wood ducks and who knows what all else.  Later on, dragonflies! And they all lose their beautiful watery home when the dam is ruined and the pond is drained.
ery good. You have officially set of the bat signal for beavers and called in the troops. She was so excited she came back that evening to film the resident builders, Look and listen to this lovely glimpse of the treasures.

Julie apparently is on NPR so I’m guessing she has a head start in all this. Use what you know and learn what you don’t! I think this is the beginning of a beautiful friendship,

 


Finally a moment to reflect on Ben’s new article about  an end of life beaver story. This one about Brittany in New York. It was published this week in the writers blog “The last word on Nothing.”

Brittany and the Beavers

Since I published a book about beavers two years ago, I’ve heard from dozens, maybe hundreds, of readers with their own beaver experiences to share. This is a wonderful perk of authorhood: When you tell your own story, you attract others. I’ve gotten emails from folks who have hand-fed blackberries to wild beavers, who have seen beavers build dams entirely of rock, who have watched beavers frolic like seals in the Baltic Sea. Just last month I received the unsolicited memoir of a guy who once resuscitated a drowning beaver. Yes, mouth-to-mouth. 

Most writers, I’m sure, get some version of this correspondence. Still, there’s something about beavers — their human-like family structures, their penchant for construction — that seems to foster personal connection. They enter lives in unexpected ways. They channel joy and grief. Today, I want to relate one such saga, courtesy of a woman named Brittany. I’ll warn you that Brittany’s story is about illness and death. It’s also about life and love. And beavers. It’s definitely about beavers.

Every time Ben introduces a story line I start to relax and settle in for a nice long read. He has such a winding and familiar prose style that I couldn’t be more comfortable unless the subject was about beavers. Which of course it is. This time through the eyes of Brittany in Cuba New York.

In adulthood, the siblings drifted apart. Zach stayed at home, cycled in and out of college, worked at a cheese factory. Brittany, a high achiever, moved to West Virginia to teach at a university. Around 2010, though, she, her husband, and their kids returned to Cuba after receiving terrible news. Zach, at age 24, had been diagnosed with glioblastoma, an aggressive, almost invariably fatal brain cancer. Brittany’s brother was going to die.

One day in 2016, Brittany, along with her sister, her niece, and her mom, took Zach on a final field trip. A lifelong animal lover, Zach had a special thing for turtles; he even owned a painted turtle, a female named Gary, that their sister brought back once from Myrtle Beach. (It’s still alive today, in the care of their mother). Zach’s dying wish was to visit Moss Lake, a turtle hotspot. “I can remember trying to get him in the car — it was so tragic but so funny,” said Brittany, who has a gift for smiling through pain. “It’s horrible because he’s dying, he can’t move. But at the same time, we’re all laughing because his gut is hanging out, he’s swearing, there’s a cigarette coming out of his mouth, his catheter is falling out of his pocket.” Alas, the turtles weren’t out, but it was still a lovely afternoon. In a photo Brittany sent me from that day, Zach sits flanked by his family, five backs to the camera, their arms twined around each other’s shoulders, the dark timber across the lake reflected in the water’s silver bowl.

Two weeks later, Zach died. Brittany’s family poured his ashes into Moss Lake — illegally, which Zach would have appreciated. The turtles surfaced and ate them all.

So the lovingly described brother dies, and the family builds a bench or him at the cemetery. And she like to go there to remember him. And the cemetery is in a wetlands which is where we all should be buried..

During one of her vigils soon after Zach died, Brittany spotted a V-shaped wake carving through the swamp. The wake was cast, she realized, by the head of a beaver, the first she’d seen. Brittany, a casual but enthusiastic nature-lover, was thrilled. When she next came to the cemetery, she saw beavers again, and again the time after that. Beavers are ordinarily nocturnal, but this colony was bold and active during the day, perhaps because it had habituated to the cemetery’s foot traffic. Soon Brittany was visiting five days a week, for hours at a time. “I’m at the cemetery trying to feel some peace,” she wrote in her journal one day in July. “And I saw the beavers and Zach would have loved them.”

Peace, at the time, was hard to come by. In the aftermath of Zach’s death, Brittany’s family melted down into chaos and drama; no need to divulge specifics, but suffice to say that, when she compares the situation to Jerry Springer, she may actually be underselling it. The beavers transcended the bullshit. “They were so majestic, so blissfully unaware of the horrors of everything going around,” she recalled. They were, it seemed to her, manifestations of our better natures. They lived in tight family units, like Brittany’s own clan, and they were fiercely devoted to their kits, as Brittany was to her children. But they were also blessedly drama-free, practical, industrious. They did not dread death; they did not betray each other. They were akin to humans, yet superior to them. They also led double lives — sleek and graceful in the water, clumsy and uncomfortable out of it — that seemed to reflect humanity’s own dualism, Zach’s own dualism, how we can at once be so generous and kind and callous and mean, how we all contain multitudes. 

Yes, of course these are the very same thoughts I’ve had watching beavers. And maybe you’ve had too. Because there is nothing new under the sun. It has all been done before.

A few months later, Brittany’s health began to deteriorate. She felt dizzy and fatigued; she struggled to walk. At the hospital, a wild thought rushed through her aching head: that, although glioblastoma is not hereditary, she had contracted the same disease that felled her brother. She didn’t fear death itself, but she was terrified by the thought of leaving behind her four children. The next day, she received her diagnosis: an aggressive form of multiple sclerosis. Another person might have grieved. Brittany, though, had expected incurable cancer. “I was so relieved,” she said. “I don’t think I even cried once. Like, whatever, I’ll get over it.” She threw herself into exercise and literature; although she occasionally requires a cane, her life has continued mostly unaltered. 

Yeah, yeah, yeah. All the best beaver people do. Who knew I was a type?

Brittany and I spoke in late May, amidst an unprecedented societal lockdown. All over the country, people were adjusting to smaller, quieter lives, as Brittany had, and escaping their deepening depressions through nature, as Brittany once did. Gardening was ascendant; so was birdwatching. We were all trying to connect with forces deeper and simpler, to commune with creatures blessedly detached from a world that we’d ruined. That, in the end, was what Brittany loved most about beavers: “They’re so unaware,” she said, “of the shit that we go through.”

Yup.


Hot diggety dam! Today is going to be a great day, can’t you feel it? What am I saying. it is a great day already! Guess what our friends at Phys.org wrote about yesterday? An actual article about beaver science! Not just one that actually describes what beavers do every day and doesn’t give them any credit. And stay until the end because as good as the article is, something EVEN BETTER happened last night.

Beavers are diverse forest landscapers

Beavers are ecosystem engineers that cut down trees to build dams, eventually causing floods. Beaver-induced floods make forest landscapes and habitats increasingly diverse, but very little is known about the long-term effects of beavers on European landscapes. Researchers at the University of Eastern Finland and the University of Helsinki examined the history and occurrence of beaver-induced floods and patch dynamics in southern Finland. They used a unique dataset of field observations from 1970 to 2018.

Go on…I’m listening…

“Beavers can help to restore wetland ecosystems and entire boreal forests, and they also help in conserving the biodiversity of these environments,” researcher Sonja Kivinen from the University of Eastern Finland says.

Oh yeah, baby. That’s what I’m talking about. They sure can. I assume Castor Fiber? Not in Finland.

The European beaver was hunted to extinction in the 19th century Finland. Nowadays, the study area is home to thewhich was introduced there in the 150s. The American beaver builds similar dams as the European one.

Oh that’s so sweet. So this article is about OUR beaver. Remember that.

“The spread of the beaver in our study area has created a diverse and constantly changing mosaic of beaver ponds and beaver meadows of different ages,” Kivinen says.

The researchers observed that the number of beaver-induced flood sites grew by more than 11-fold over the study period. In addition to creating new flood sites, beavers also often use old sites to cause new floods. The duration of an individual flood and the frequency of floods can vary greatly between different sites, resulting in an abundance of habitat patches with different environmental conditions.

“Thanks to beaver activity, there is a unique richness of wetlands in the forest landscape: flowages dominated by bushes, beaver meadows, and deadwood that can be used by various other species,” university lecturer Petri Nummi from the University of Helsinki says.

Credit where credit is do! Yes that is exactly what beavers do better than anyone else. Thanks so much for noticing! Shh this is my favorite part:

Indeed, beaver-induced disturbances are more predictable in diversifying the forest landscape than for example fires or storms.

Well, at least they like them in Finland! Beavers might be killed in Scotland and Russia and America but some Fins apparently know what a good thing looks like. I’m told the country has no official motto, but the unofficial slogan is “Sisu, Sauna and Sibelius“. Sibelius is their famous composer. Sauna is the soaking hot bath that we all know and love.. And Sisu is a Finnish concept described as “stoic determination, tenacity of purpose, grit, bravery, resilience, and hardiness and is held by Finns themselves to express their national character.”

Umm…like a beaver.

Ready for the good local news from last night? This was photographed by a neighbor in her backyard a few blocks up the creek from where I live. She said the beaver was awkward and moving weirdly. That sure looks to me like a beaver trying to haul down a big tree he might have cut from up on the bank.

Gee I wonder why would a beaver do that?
