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

Category: Beaver Chewing


On a mid week morning where news is slow, I have to ask myself, honestly. Am I ready for another beaver alarm from South America? This time on PRI for god’s sake. It is stunning to me that after everything that’s been done to the region from military coups, massive burning, agricultural campaigns that destroyed native plants, and ripping out trees at an alarming rate to plant soya for biofuels – we have the gall to blame BEAVERS for destruction in South America.

It’s open season on Patagonia’s voracious, disruptive … beavers?

Even furry, seemingly friendly creatures like beavers can become big problems when dropped into an ecosystem with no predators to keep them in balance.

That’s what happened in Patagonia, where the busy dam-builders are profoundly changing the once-pristine region that spans the southern ends of Chile and Argentina.

In 1946, 25 pairs of Canadian beavers were brought to Patagonia to kickstart a fur industry. That business didn’t take off, but the beavers flourished; there are now about 100,000 beavers in Patagonia that don’t belong there.

They’ve completely changed the entire ecology of the region,” says Derek Mead, editor-in-chief of Motherboard, a digital magazine and video channel.

The industrious beavers have chewed down trees and diverted rivers, reshaping the area’s river system. That’s a useful function in their normal habitat, but in Patagonia, they’ve turned beech forests into barren wastelands. The trees, cut down to stumps by the beavers, can’t regenerate or hold onto the soil. Rains and heavy flooding erode the soil, turning a previously dense forest and tight river into an open pit, Mead says.

 Lets start with “no natural predators”. I understand since they are 5000 miles away from their natural predators they are not likely to get eaten by a bear. But hmm I wonder if there are any predators in Argentina and Chile that might like a little exotic beaver meat? Let me just check what’s around there, “87% of South America’s carnivore population occur in Argentina”. The maned wolf for one, and a variety of others. This book outlines seven species of carnivores living in the Pampas. Not to mention a dozen different kind of Caiman (crocodiles) that can be found anywhere there’s water. And let’s not forget those in that Youtube video. I guess no “natural predators” but a host of “unnatural” ones. And It’s not like beavers can offer much self defense.

Seven years ago they were whining that the beavers had grown SO LARGE in South America that they were eating FISH. Seriously. At least they seem to have stopped that nonsense. Now they are paying anyone to hunt them and selling the meat in local restaurants.  I’ve been in the beaver biz for so long, I  already wrote about it in 2008.

Never mind. Go ahead. Blame the beavers for everything that’s wrong in your lopsided countries. I admit they don’t belong there. And everyone deserves a scapegoat.

Oh and if you don’t think the PRI article and film is stupid enough for me to complain about, check out the comments on Youtube. Grr.


Yesterday was supposed to be a languid Wednesday where I sat around and practiced my talk for SARSAS on Monday. Instead my little desk exploded into beaver central around 1 when someone who had been referred by Brock Dolman wrote me from Winters that they were trying to save a rare piebald beaver that was living in a section of creek going to be destroyed in the name of progress.

I assume you are like me and had never really heard the word “piebald” before, so you might need a short refresher course.  The Dictionary definition is “Spotted or patched, especially in black and Piebaldwhite.” A pinto horse is piebald. Rarely a hunter will get lucky enough to shoot a piebald deer. And very very rarely we have stories of piebald beaver.

Remember that before the fur trade we used to have all colorations of beaver. Blonde beaver. Redhead beaver. And Piebald beaver. After the population was nearly destroyed that variation vanished. Well almost vanished. Because apparently there is at least one colored beaver left in California.

CaptureAnd, there’s something else you shouldn’t wait to see, if you can see it at all. I’m outing a secret, and am gambling on the goodwill of humanity against stupidity (a big gamble, I know): There’s an extremely rare piebald beaver that frequents this area. Local nature photographer and wildlife expert, Alejandro Garcia, camped out for hours just to get a photo of it, which I’ve seen, and it’s pretty darn amazing. It’s a regular brown beaver in all ways, with a thick white stripe in its midsection like an ice cream sandwich.

 Alejandro told me there are only a handful of piebald beaver in existence. I googled it, and aside from some horrific trapping sites based in Arkansas, the only information I could find was from a book written in 1876 by John J. Bowman, entitled, “The Emigrant and Sportsman in Canada — Some Experiences of an Old Country Setter.” Bowman merely says, in a story about his experiences with wild beaver, “I saw one piebald beaver; his back was black, his sides white, and belly reddish.”

 That’s it. The sum total of all the information about piebald beavers, almost as rare as a dodo, and, by a miracle of nature, there’s one living in a little pocket of natural habitat along Putah Creek in Winters. What a great mascot this animal could be for our little creekside town. But no. We’re glibly forcing it to “move on.” If you want to get a glimpse of it before it’s gone, don’t wait. The bulldozers are coming.

An ice cream sandwich beaver! How could I not come to full attention! I conferred with the author, contacted some professors at UC Davis to see if we could get some interest,  swapped emails with Beth to see if there was anything that National Wildlife Federation could do, called Sarah Koenisberg to see if she might want to film it for her upcoming documentary, and talked with the director I knew at Fish and Game. He pointed me to his counterpart in Winters who, like everyone I talked to, was very interested but wasn’t sure that a beaver could be protected just for its coloration. I reminded him that it was kit season and that there was a good chance that at least one of the kits would have some coloration too. (OMG) And he was more interested.

Now here’s where the story gets very very fascinating.

In our amiable chat he reminded me that beaver were depredation-able and nuisance permits could be issued for their death. I said I understood that very well, and that in fact there were  no limits on how many beaver could be written into the permit for depredation. He said, that’s not true. And with no hesitation at all I said come on! I just reviewed all the permits in California for the last two years an there were 51 unlimited permits issued!

‘And he agreed that used to be true but two months ago there had been a meeting and they were told not to issue unlimited permits — then he stopped talking abruptly surprised  — maybe that was because of you!

I have zero idea whether it was because of me, but I do know that a third of the permits we reviewed were written for ‘unlimited’ numbers of beavers, and now according to him, none will be. NONE.

I was so focused on finding a way to save that piebald beaver it really didn’t sink in until later. No unlimited permits! I wish I’d asked about that meeting where they were told not to do it. Was it regional? Or with a higher up? Was it time limited? Was there any push back about it?

Of course there were more people to call about piebald beaver, so I had to stop feeling surprised and just feel like I might be able to help. Then there were several forwards about the Fargo beavers and the war room had to redirect. It’s always good to know your work matters. I did what I could for Piebald beaver. And maybe some one will share a photo soon.

Now it’s off to Fargo!

‘Is this the only way?’: Fargo Parks beaver cull draws criticism

 FARGO—A growing chorus of animal rights supporters wants the Fargo Park Board to reconsider its plan to trap and kill beavers in city parks along the Red River.

 One of the leading voices is Megan Bartholomay, a 38-year-old Fargo resident who believes the board’s plan is barbaric.

 “We’re a civilized community living in 2015,” she said. “Is this the only way? What else have we tried?”

One supporter of Megan tracked down Carol Evans from the PBS documentary (it’s always easier to find the emails of government employee!) and she forwarded it to me to see if I could help. I gave lots of thoughts and resources and am eager to see what happens in Fargo. It’s not an impossible battle because there is already lots of beaver intelligence in the state. Just look at this comment I highlighted in 2012 in Fargo from Game and Fish!

“Probably the most economical way of dealing with beaver is wrapping the trees, probably a couple three feet up as high as a beaver can stand off the ground, with chicken wire or some kind of wire mesh to keep the beavers in, they’ll leave it alone.” says Doug Leier with North Dakota Game and Fish.

Go team Fargo! It’s up to you now.


Busy as a beaver: unique partnership helps maintain riverside trees

UI allows the native beaver to gnaw down invasive trees, while saving protected species.  Keeping the University of Iowa campus beautiful is a full-time job. Luckily, the UI Landscape Services team gets a little assistance each year in the form of some notoriously busy helpers: the nocturnal, semi-aquatic beaver.

 Beavers, a native Iowa species, typically gnaw down trees along the UI campus riverbanks, which is fine for some tree species, but not for others. Instead of stopping the beavers’ behavior, the tree care team decided to work with the beavers’ natural talents. By wrapping valued native and planted trees with protective wire, the invasive and common native species like Boxelder, White Mulberry, Siberian Elm, Willow, Green Ash, and Silver Maple, are left for the beavers to utilize in their underwater homes for food and shelter.

It is true that beavers can be destructive if their work is not redirected; however, under the right circumstances they can be used as an effective, low-cost management tool. Next to humans, no other animal appears to do more to take care of its landscape.

“While there may be a number of trees gnawed off along the riverbanks, the beavers’ work will not kill the tree as the root system is still intact, so the tree typically will resprout. As long as they continue to do this to the invasive species, we don’t have a problem with them. They’re a spoke in the wheel of life as are the trees, as are we,” says Andy Dahl, UI arborist. “We’re happy to have them as our partners to manage the riverbanks.”

Go Andy and UI! Awesome to read that the Hawekeye State has at least an island committed to coexistence. Sometimes I get the feeling that the beaver good news is spreading so far and permeating so deep that there eventually won’t be a single state where it doesn’t exist.

Except Oklahoma. Because, you know.

“The flood recovery is helping us to clean up and better celebrate the Iowa River. Those busy beavers are helping to contribute to that effort,” says Don Guckert, associate vice president of Facilities Management.

Even in Fargo ND the attitude towards beavers is changing. Just look at this:

Beavers beware: Fargo Park Board mulls trapping, killing

FARGO—Because of tree damage caused by beavers along the Red River, the Fargo Park Board will meet tonight to consider trapping and killing the animals in hopes of reining in their population.

“We’re not trying to eliminate all the beavers,” said Dave Leker, director of parks. “We’re just trying to reduce them.”

 Leker said the district has received a number of calls from residents worried about beavers harming mature, riparian trees. He said there’s no problem with beavers using small trees for food and dam building, but the destruction of decades-old trees concerns district officials.

 Sam DeMarais, the district’s forester, said he’s counted roughly 70 trees gnawed by beavers in city parks. Many of the trees have been felled, and in other cases, beavers have chewed off the bark all the way around the lower trunk. This is known as girdling, which is a death sentence for a tree, Leker said.

“Beavers are part of the natural ecosystem, and so are trees,” he said. “It’s kind of a no-win situation. You’re going to have people that, you know, are rooting for the beavers, and you’re going to have people that are rooting for the trees.”

Hmmm Fargo hasn’t exactly exhausted their resources trying to solve this problem. But it’s still better that they don’t want to kill ALL the beavers. An inquiring mind might ask how many beaver they have? And how they’ll chose which ones to kill?   The Sophie’s choice of beavers, I guess. They are going to contact USDA next. Now how could that possibly go wrong?


Oh! Looks like our beavers approve of the watershed stewards hard work! Jon wrapped half the new stakes on friday, and they were quick to take a nibble. They’re all protected now!

The whole thing gave me an idea…now I just need some funky beaver folks to record this.  (Ahem).  Free beaver t-shirt for the artist(s) that give this wings! Pass it on. Hit play for some mood music while you read.

TREE WRAP RAP

When the beaver starts a’chewing
There’s a thing you should be doing
If you want to save your treeline
Better go and make a beeline
For the wire
Get a plier
It’s not dire
I’m no liar
 
Do the tree-wrap, rap
Do the tree-wrap, rap
 
 In the yard and in the garden
Wrap it up and beg their pardon
Not too tight, the tree will widen
And it the wire it will tighten
Wire thicken
Not for chicken
Paint with sandy
Comes in handy
 
Do the tree-wrap, rap
Do the tree-wrap, rap
 
Save your maple and your aspen
Here’s the point that needed graspen’
Come protect the plants that need you
And the fruit trees that will feed you
I’m not crazy
Don’t be lazy
Stop your trappin’
And start wrappin
 
Do the tree-wrap, rap
Do the tree-wrap, rap!

Don’t blame me. You knew it had to be done.

Oh, and I know we’re all relieved to know there’s at least ONE stupid person in Sweden. The article is kind enough to say he wasn’t hurt. But mark my words, it will be everywhere as a life threatening attack tomorrow…

Beaver bites bus passenger in Sweden

Pentti Savola, 58, was among a group of early morning commuters waiting to get a bus to work when the animal came up to him and bit his leg last week.

 “It was lightning fast. I never thought that an animal that looks so clumsy could be so crafty,” she told Swedish news site mitti.se.

 He said that he may have stressed the animal out when he tried to take a photo of it with his mobile.

 But after his own stressful experience, he said he wanted to tell his story to warn children that they should not pet beavers without knowing more about the animals.
