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

Month: August 2018


Recently I received a huge stack of beaver papers from Duncan Haley of Norway. He’s a beaver buddy that makes a point of letting folks know the latest beaver research. Most of it is far over my  head about population dynamics and genetic skewing, but I am always enthusiastic and grateful so he keeps sending them anyway.

I sent him back the article about Ben’s book in National Geographic and I was surprised he hadn’t seen it already. In fact I realized none of the reviews I covered here had been European. Which prompted me to mention this omission to Ben who said he talk to his publicist.

Well I don’t know if this has anything to do with that conversation or would have happened anyway, but I was happy to see this yesterday.

Busy beavers: in praise of man’s natural ally

The British experience of beavers is somewhat limited. Most of us haven’t been lucky enough to have spied an immigrant rodent in the wilds of west Devon, or paid a visit to Knapdale and Alyth in Scotland.

Eager is the story of why the American (and to some extent European) landscape looks the way it does — because of those mountain men and fur trappers who rampaged across North America 400 years ago, killing beavers for their soft fur and mindlessly altering the topography of the continent simply because of the European fashion for beaver hats.

But Goldfarb seeks to show how beavers are so much more than this; creating meadows, re-forming rivers, mitigating floods, helping salmon populations, even halting climate change. Yet, maligned and misunderstood by modernity, this creature has continued to be trapped, shot and killed by those who see its natural architecture at odds with human habitation.

This is such a lovely and well-written review. Someone on facebook remarked that it was their favorite and I can see why. You can tell Ben made contact and left an impression. Oh and there’s even a MENTION a certain  beaver festival from foreign soil.

These are some of the characters you meet in the book — people, who for one reason or another, have been drawn into the beaver’s orbit and built their enthusiastic home there, convinced the world could benefit from working with these aquatic rodents. There are volunteers so enthralled by the beaver that they have dedicated a festival to him (or her — beavers are very difficult to sex, but the male expresses an anal liquid that smells like motor oil while the female’s gland juice smells more like cheese).

Ahh!

There are also the ecologists, fluvial geomorphologists, farmers, scientists, salmon fanatics, ranchers, Scottish aristocrats, animal husbandry eccentrics and wildlife biologists. All these characters, as described by Goldfarb, are making the case for beavers as a natural ally of humanity.

This is a book densely packed with knowledge and research. For anyone un-familiar with ecological terminology, it can present difficulties, though Goldfarb does his best to explain the jargon. But his enthusiasm for the subject shines through. By the end it’s hard not to become a beaver believer yourself.

Well that ought to sell a few copies in the UK! Nice job Felicity Morse. This is a great introduction to a book that will become the beavers best friend.  I’m sure Ben is very pleased to see the reach broaden.

A child’s view of the beaver family

And speaking of beavers. the fur-trade and other calamities. Brock Dolman of the OAEC came across this drawing reprinted in a used Time Life Book from 1973 called The Trailblazers.  This illustration was put together by James Isham in 1743 who was a trader employed by HBC. He also happened to be an avid journalist and took detailed notes on his experiences.

The drawing caught my eye because it reminded me at first so much of this drawing by a older boy our very first Earth day in 2008. But even more so because, compared to so much art of the day, it was very detailed and accurate. I’m super excited about this drawing and have a couple things to puzzle with you after you see it. So meet me after the break.

Here’s the scan Brock did from the book.

James Isham: Beaver hunting

You’ll need to double click on this to really get close enough to read the text, but its worth doing. There is so much detail in this description about how beavers were hunted and pursued. But also so much mystery. Like the little chamber off the lodge in number 6 where the “Half beaver” lives (muskrat?) or the “vaults” which beavers can use to escape (burrows or tunnels?) Or the anatomical diagram which describes the tail, liver, penis bone, castor sacs and “Lights” (eyes?).

But also the fore feet?

Why describe the forefeet especially and not the back feet? The back feet of a beaver are way more curious by virtue of their being webbed. Was their some medicinal use that I don’t know about that made a market for forefeet?

I searched for hours on the internet and couldn’t come up with more detail or a better image of this map. What I did find was a reference to a researcher Adriana Craciun who believed very convincingly that this image wasn’t the work of Isham, but had in fact been drawn by a Cree indian who knew the trade.

One example of an artifact that Craciun discovered is James Isham’s Observations on Hudson’s Bay, a 1743 manuscript book that had been forgotten or ignored in the Hudson’s Bay Company archives in Winnipeg, Canada. Within the book, Beaver Hunting, an anatomically and technically detailed watercolor illustration, shows Cree people hunting, and includes a 30-point explanatory key. To Craciun’s trained eye, the illustration shows far more. “I think it may have been painted by a Cree illustrator, and at the very least shows the interconnected worlds of the Cree, English, and animals on the Hudson Bay, before the 19th-century British popularized their images of the ‘empty’ and ‘uninhabited’ Arctic,” she explains.

Hmm when I look at those LONG english noses and pipes I’m tempted to think someone’s highlighting how weird english faces look to a Cree? Also the level of detail is so much more direct than your average trapper would offer. Maybe the drawing of the “Fore feet” was even a kind of native trolling – teasing the clueless boss into thinking there was something special about them when everyone knows back feet are better!

Anyway, I love the drawing, and want the rest of his notes. Or at least the notes of people who observed it directly. Apparently if I was affiliated with an institution I could download this.

Hint Hint.

Today’s beaver news is brought to you by “SOMETHING WONDERFUL” and “SOMETHING STUPID”. Which helping would you like first? My Catholic upbringing always directs me to get the bad thing out of the way first, so let’s talk about beavers and carbon, shall we?

This is from yesterday’s phys.org, but it’s not the kind of report that gets a special beaver graphic.

Beavers have an impact on the climate

“An increase in the number of has an impact on the climate since a rising water level affects the interaction between beaver ponds, water and air, as well as the balance of the zone of ground closest to water,” says Petri Nummi, University Lecturer at the University of Helsinki.

Growing beaver populations have created a large number of new habitats along rivers and ponds. Beaver dams raise the water level, enabling the dissolution of the organic carbon from the soil. From beaver ponds, carbon is released to the atmosphere. Part of the carbon settles down on the bottom, ending up used by plants or transported downstream in the water.

Oh so THAT’s the problem is it! All those damn beavers releasing all that carbon by saving water for us to drink and water our crops. Forget the fossil fuel industry, lets stop all the beavers!This is my favorite paragraph. It is so rich with knowledge and precision.
urrent estimates indicate that beaver ponds range from carbon sinks to sources of carbon. Beaver ponds and meadows can fix as much as 470,000 tons of carbon per year or, alternatively, release 820,000 tons of carbon annually. Their overlapping functions as and sources make landscapes moulded by beavers complex.
Okay, either beaver ponds are REALLY REALLY GOOD or their REALLY REALLY BAD, and our scientists in Helsinki are hard at work flipping coins to find out which,

Alright we’ve eaten our spinach, now lets settle in for our dessert, shall we? This wonderful work is from our friends at the Miistakis Institute and Cows and Fish. It will be a great resource for handing out to agencies or officials who don’t know (or need to reminded of) their fish facts. Give this a second to load and don’t forget to check the second page because its worth it.

It’s good to see that mlive picked up Nancy May’s story and did a profile of it. The more people that know this story the better chance that the next beavers will stick around longer.

Mackinac Island’s beloved beaver family has disappeared one by one

Beaver in snowy waters: Nancy May, Mackinac

Vanishing Act:

MACKINAC ISLAND, MI – A beaver family that had become social media darlings to locals and tourists alike on Mackinac Island began disappearing one by one earlier this year, with the family’s last kit vanishing this month.

Some believe the animals fell victim to illegal trapping. A few believe someone on the island must know something about what happened to them, prompting a GoFundMe effort to raise reward money for information.

As their absence from “the Cove” continues to be felt, we’re taking a look back at their antics which captured so much attention in recent years. It comes courtesy of Nancy May, an island resident whose photos of the beaver parents and their kits drew avid followers on Facebook.

May has shared some of her pictures with MLive readers, and her story of how she became one of their biggest fans.

MACKINAC ISLAND, MI – A beaver family that had become social media darlings to locals and tourists alike on Mackinac Island began disappearing one by one earlier this year, with the family’s last kit vanishing this month.

As their absence from “the Cove” continues to be felt, we’re taking a look back at their antics which captured so much attention in recent years. It comes courtesy of Nancy May, an island resident whose photos of the beaver parents and their kits drew avid followers on Facebook.

May has shared some of her pictures with MLive readers, and her story of how she became one of their biggest fans.

Nancy’s touching article (which we printed a week ago) appears with her great photos that I was happy to see. It is followed with some comments from the furbearer specialist of the Michigan Department of natural resources, which seem less likely.

Adam Bump, a furbearer specialist with the Michigan Department of Natural Resource’s Wildlife Division, said while he can’t speak to this particular beaver family on Mackinac Island, he does know that some animals like their privacy. And they don’t necessarily need all the help that people think they might to survive Michigan’s harsh winters.

He wondered in this case if perhaps there were too many people coming too close to the lodge.

“Some beavers can get used to people and have no issues,” Bump said of the species, clever little wetland engineers which can be found throughout Michigan’s watersheds. “But the repeated, constant presence of people could be a potential reason” for their disappearance, he said.

“Maybe something happened there and they moved on their own?” He would recommend that people enjoy and watch wild animals from a distance, knowing that they “do OK on their own.”

Okay, Adam. I’ll agree it’s better when people keep their distance. But that doesn’t explain why the beavers lived their happily with their fan base for 6 years and then decided to leave? I’d be more likely to think that after the big freeze and damage to their lodge they assumed they needed to find a safer home in deeper water to raise this family, but that doesn’t really explain why didn’t the kits leave earlier?

I don’t know. I’ve been around beavers a long time, and I have seen kits make crazy decisions without their family. So to be honest, my minds not exactly made up on this story. It wouldn’t surprise me to know they were killed, because there are always villians in the beaver drama, but it also wouldn’t totally surprise me to learn they found a new home somewhere else, and that the kits just stuck around for a while and then made their way there eventually. 

If harm came to these beavers from human hands, you would think the story would travel. These beavers were so visible that someone knows what happened and beaver rumors have a way of getting spread. If, on the other hand, the beavers just decided on their own to throw in the towel and start over somewhere else, they wouldn’t talk about it.

For now I’m going to a hope that there’s a  chance they’re doing okay.

What I know for sure is that the world is a better place when people gather together to protect and observe beavers, and that learning about the wild neighbors of your community is always worth doing. I know that children who are given the chance to witness beaver families are smarter and stronger than children who don’t. And that any woman who photographs beavers through many seasons will be forever transformed by the experience.

Thank you again, Nancy.

Mackinac beaver: Nancy May

No new Ben glories this morning so that gives me time to catch up on a story that’s been sitting in my inbox a while. It’s a remarkable description of a close encounter with a disperser from the very tip of the island of Newfoundland in Canada.

Wayward beaver in Port aux Basques causes concern for animal and any people it could have encountered

Residents along Water Street East in Port aux Basques had an unusual visitor on Friday, Aug. 10, when a young beaver was spotted walking along the sidewalk.

As there no ponds close to the town, George Anderson grew concerned about the animal being so far from its natural environment in the 30 degree heat they experienced that afternoon. 

Anderson grabbed his mop and walked along with the animal, going up and down the street for 10–15 minutes to ensure it did not wander onto the road and get hit by a car. The beaver initially hissed at Anderson but displayed no other signs of aggression.

George’s wife, Shirley Anderson said the beaver was so big, “one guy thought he was a cat. A big cat. But he was too big for a cat. “

She also said the beaver had a notch missing from his tail and that her neighbours speculated that might have something to do with it being found so far from fresh water.

Well that was nice of Anderson, to act as beaver guardian for a while. Thanks for that. I’m a little curious about the mop though.

“They said that he (the beaver) was probably banished from his family,” Shirley said. “They say that when there’s a piece missing from his tail, he was lazy and his parents threw him out. That might just be an N.L. saying, I don’t know. I’m from Scotland.”

George managed to guide the beaver into his own driveway, where it crawled into the shade under his car and took a long nap. Shirley believes the beaver was likely exhausted.

“I think he was walking around for awhile,” she said. “He was tuckered out and he got under the car and laid there for two-and-a-half hours before anybody came and got him.”

“Our understanding is they don’t like salt water but Water Street runs along the ocean and we don’t know how else it could have gotten here,” Neil commented.

Shortly after 3 p.m. town employees Alex Hodder and Philip Roberts arrived with a large dog cage and captured the beaver within 15 minutes.

“They just put him in a cage and went off with him,” Shirley attested. “They said they were going to put him in a pond up on the highway.”

What is it about city employees that makes them all look the same? Can’t you just see the gleeful sorts in Martinez in their public works orange shirts excitedly trapping our beavers? There but for the grace of God, I say.

“One of the issues the people were saying, is that you’ve got all these kids out.

“They (beavers) are not mild mannered creatures. They can be quite vicious. It’s wandering around with kids playing outside and you really don’t know what could have happened. Does this not occur to anybody from all these agencies? It’s just like pass the buck, pass the buck, pass the buck.”

Save the children! A beaver on the loose! Whatever will become of Susie?

In response to The Gulf News’ request for comment on why a beaver would be found so close to salt water, and far from any freshwater ponds, John Tompkins, director of communications for the Department of Fisheries and Land Resources, responded with the following e-mailed statement:

“Beavers are territorial and individual, usually juveniles will leave their natal colonies to locate suitable habitat and establish new colonies. In the process, the animal may subject itself to a variety of stresses including coming in contact with people in unpredictable locations. It is not uncommon for a beaver to use the ocean as a mode of transport.”

Ah John! What a very wise and informed comment. Are there any more like you at home? The rest of this story reads like a crazy Lavern and Shirley episode, but you, you know your stuff. That’s mighty rare when it comes to beavers in your neighborhood or ours.

Let’s hope he likes the new pond. And it’s not back where he started from to begin with after all that work!


Hmm Ben shares our horror about the beaver destroying ponds story, and says that I’m not the only one who suggested a companion piece to his book but written for children is worth doing. Gosh, it’s too bad he doesn’t know a nice child psychologist who can help.

In the meantime the National Geographic beaver headline is making the rounds and I keep getting emails from people who are happy to see my name come up in the article, which is fun. And there are more beaver headlines just waiting to be explored.

Eager beavers could benefit British agriculture

“Beaver engineering at Combeshead, particularly the building of dams has transformed the environment, increasing water storage and creating diverse wetlands,” Dr. Alan Puttock of the University of Exeter told the Daily Mail. “Our research has shown that beaver activity can slow the flow of water following rain storms potentially providing a valuable component to future flood and land management strategies.”

The study found that the beaver dams prevent nutrients and soil from being carried downstream during by trapping sediment, benefiting soils both upstream and downstream.

A study released in May found that 70 percent of the sediment trapped by the dams had eroded from grassland fields farther upstream.

“We are heartened to discover that beaver dams can go a long way to mitigate this soil loss and also trap pollutants which lead to the degradation of our water bodies,” Dr. Richard Brazier, who led the study, said in a press release.

Me too! I am heartened by the good beavers can do and the good you have done in broadcasting it. Thank you!

Now a great dose of ‘heartening’ watch this video sent to me by the watchful eyes of Robin Ellison. Tell me honestly if that isn’t the sweetest thing you will see all week. I  mean sitting in a tubby turtle pool is always wonderful, but this just takes all the cakes.
