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

Category: Creative Solutions


Some days there is so little beaver news that I am left sorting through my ragged thoughts and trying to find something new to say about them. This week has been a beaver explosion, so I can barely keep up. First there is the smart new beaver page out offered by Esther Lev of the Wetlands Conservancy and some graduate students who accepted the beaver challenge. You will have fun browsing the projects. Use the link to visit the site which connects to each project. I’ll let them describe the ‘zine’ themselves.

During the 2017 Winter Term, eight graduate students from the Master of Urban and Regional Planning, Master of Fine Arts, and Master of Environmental Science and Management programs at Portland State University engaged in a study of beavers in the Pacific Northwest.  The question was whether better understanding the beaver could help us understand more about the culture, identity, and character of the Pacific Northwest, particularly for those of us engaged in planning and other activities with and for communities in the region.

The project had two components.  First, each student identified a topic associated with beavers, and developed a research paper that explored that topic.  All of those papers are posted here for your use and enjoyment.  During the term we read Frances Backhouse’s Once they were Hats, her very informative and engaging book about beavers in North America.  Thanks to Esther Lev, Wetlands Conservancy Executive Director, and Sara Vickerman Gage, we were able to spend a morning discussing the book with Frances Backhouse.  We gratefully acknowledge the importance of both Frances’ work and her presence in the class with us.  If you are interested in and/or care about beavers, do read her book!

Second, each student used their paper as the point of departure for creating pages for a class “zine” about beavers.  A zine is a short, self-published, and mostly hand-crafted magazine.  Usually combining words and images, the zine form attempts to both transmit information to and engage the imagination of the reader.  Preliminary research in Portland revealed hardly any zines about or featuring beavers.  We aimed to fill that void, at least in part.

3 screenTWC is who had me talk in Portland last year and is responsible for the art show “Beaver Tales” that is in its second venue. They are doing beaver-work wonders. I am thrilled that they’re on the scene and that all these students will remember beavers in their masters training.


A second exciting development came from our beaver friends in the Czech University of Life Sciences. They recently completed the English translation of their ‘living with beavers’ guidebook. There is a lot of great info on management and history, so I would take some good time to browse. There’s a great discussion of tree protection and flow devices, as well as some pretty creative solutions for preventing bank burrows. Enjoy!

Parry Sound is in Ontario Canada directly north of New York. It is famous for having the deepest freshwater seaport in the world and various hockey achievements. This morning it has decided to offer a pleasingly accurate beaver article with some very nice photos. Enjoy!

The industrious beaver is not afraid of hard work during the winter

PARRY SOUND SIDEROADS AND SHORELINES — Winter is the time of year when many wild animals living in the Parry Sound area have adapted to escape and wait out the heavy snowfalls and dropping temperatures. Bears hibernate in cosy dens, squirrels have built nests and stashed food away, and frogs have dug into the lake bottoms and drastically reduced their temperature. But the industrious beaver continues to be quite active during winter until the lakes freeze over completely, and even then this animal can be seen busily repairing any damage to its lodge or dam.

Beavers are completely adapted to an aquatic existence and look quite awkward when slowly waddling on land where they are vulnerable to coyotes and other predators. Their front paws contain claws that can easily manipulate twigs to chew the inner bark of branches – their primary food source. In the Parry Sound area, their favourite wood is the aspen tree but they will also eat ferns, mosses, dandelions, dogwood, and aquatic plants, to name a few. 

The resulting dam sets in motion an entire alteration to the ecosystem. Hence, beavers are considered a “keystone species” (one that plays a unique and crucial role in the way an ecosystem functions. Without keystone species, the ecosystem would be dramatically different or cease to exist altogether). The building of dams modifies and creates a dramatic change to the surrounding environment. The backwater flooding from the dam floods the lowland near the creek; trees die creating an opening in the forest canopy; aquatic plants and shrubs soon develop, making a favourable habitat for waterfowl, herons, moose, amphibians, fish, insects, muskrats, otters and a score of bird species. Their activity purifies water and prevents large-scale flooding.

Over a period of time the food source runs out and the beavers move on; the dam breaks and eventually a meadow forms, creating habitat for an entirely new group of species. And thus, the vital chain of evolution around a beaver pond continues.

A few years ago, the television program The Nature of Things featured a show entitled “The Beaver Whisperer” outlining the efforts of a few Canadians who have studied and/or worked with beavers, giving an in-depth account of the beaver.  The Parry Sound area is home to many beavers and if you are lucky enough to see one around twilight, watch and observe the complex behaviour of this fascinating animal. 

Nice to read that Jari Osborne’s great documentary is still making an impact! (Although it was called the Beaver Whisperers as in more than ONE). And nice to see even a brief discussion of beaver benefits from that neck of the woods.  They need all the allies they can get. I’m going to assume, that even though they’re very clever, the beaver in that photo isn’t balancing a aspen log on its back. I’m pretty sure the log is just laying in exactly the right place on the ground behind him. Although that would be quite a feat if it were possible. Think about it, how would the beaver even get the log there in the first place?

I think it’s one of those photo placement victories, like someone photographed pushing the tower of pizzaa over, or a baby holding up the moon. But it had me confused for a while, I admit. Thanks for the mystery!


Baker City Oregon is in the upper right hand corner of the state on the Powder river, which flows into the Snake river. Like Martinez it was settled early when the Short line railroad made it a stop, and is the county seat. By 1900 it was THE stop between Salt Lake City and Portland. It’s Main street looks eerily similar to ours. It even had a large Catholic population and has Cathedral because of it. Let’s think of them as a ‘sister city’.

Baker has a smaller population now than Martinez, and hasn’t sprawled like we did. Probably because it’s bordered by the Wallowa mountains that don’t take kindly to freeways. As luck would have it, that means it isn’t too far from famed USFS District Hysuzannedrologist Dr. Suzanne Fouty. Who happened to get very interested because there were some urban beaver sightings reported in this historic town.

Suzanne contacted me this weekend because she wants to use my talk to help teachers get on board with a student project that would let the children “adopt” the beavers, learn about them and sand paint trees etc. We had a nice conversation about her wish to get folks as interested and excited about the beavers as they were in Martinez.  I can’t think of a more magical combination for success than an interested hydrologist, some enthusiastic teachers and an army of child guardians. Can you? Then I found this article and realized the whole thing was already a done deal – with a sympathetic press to boot.

Beavers in Baker City

Homeowners along Powder River are learning to protect their trees from the nocturnal animals. Larry Pearson sacrificed a healthy quaking aspen last summer to their insatiable incisors, but he bears no real grudge against beavers.

“Personally I like seeing them around,” said Pearson, who has livedfor 33 years in a home beside the Powder River in north Baker City. Well, not exactly “seeing.” Pearson has seen several beavers outside the city limits, but he’s not yet spotted one of the rotund rodents near his home on Grandview Drive.

That’s to be expected, given that beavers are largely nocturnal. “I can tell when they’ve been in my yard, though,” Pearson said. Even when the animals don’t leave blatant evidence – it’s pretty hard not to notice when a 14-inch-diameter aspen in your backyard has been gnawed down – Pearson said he can usually find the muddy patch in his grass where the beavers climbed from the river’s bank.

Fortunately, protecting trees from beavers is no great ordeal, Pearson said.

“You have to put wire fencing around virtually everything,” he said.

A homeowner whose tree was chopped down by an unexpected beaver and his first comment to the press is “wire wrap it!” Have I fallen asleep? Am I dreaming? IMAGINE if the Contra Costa Times or the Gazette had a section about how to protect trees from beavers. Whoa, I’m getting dizzy, I need to sit down.

That’s what the Oregon Department of Fish and Wildlife (ODFW) recommends as well, in its “Living With Wildlife” pamphlet, which is available online at www.dfw.state.or.us/wildlife/living_with/beaver.asp

Actually, landowners have a few options with beaver-proofing, said Brian Ratliff, a wildlife biologist at the ODFW office in Baker City. Wrapping tree trunks with metal flashing is effective, he said.You can also use welded wire fencing, hardware cloth, or multiple layers of chicken wire.

Regardless of the material, you should wrap the tree to a height of at least 4 feet, Ratliff said.

“When beavers stand on their tails they can reach pretty high,” he said. If you choose chicken wire or fencing, you should leave a 6- to 12-inch space between the cage and the tree trunk, because beavers might try to wedge their teeth through gaps in the wire to get at the tree (this isn’t a problem, obviously, with metal flashing).

You should also reinforce the cage with rebar stakes or other supports, as beavers, which average 40 pounds at adulthood, are capable of collapsing flimsy wire barriers. To protect a large area rather than individual trees, ODFW recommends building a fence, at least 4-feet high, made of welded wire fence or other sturdy material (chicken wire is too flimsy).

I like to think of myself as a generous woman who only wants the best for others. But sometimes, when I read an article like THIS published a full 10 months before Suzanne even got interested and involved, before the school children even circled the wagons, or the town pushed back, I get crazy JEALOUS.

Some people have all the luck!

Baker city, you have started the footrace with a 10-mile lead. Already your papers are sympathetic and your affected citizens are cool-headed. You have interested scientists inches away that will help you move forward. And you of course, have us in your corner. With all the help you could possibly ask for.

I believe, Baker City, if you can’t save these beavers, no one can.

Pearson said he didn’t notice any signs of beaver activity on his property until a few years ago.That coincides with ODFW’s experience, Ratliff said. “In the past two years or so we’ve started to get more reports about beavers, and to see more signs of their presence here in town,” he said.That’s not especially surprising, Ratliff said.

Beavers live along the Powder River both upstream and downstream from Baker City.

“Beavers are very good at migrating both overland and along waterways,” he said. “And the Powder River in Baker City is pretty good habitat for them, minus the fact that it’s through town.”The river’s relatively flat gradient and low velocity are ideal for beavers, Ratliff said. (One reason the animals build the dams for which they are renowned is to slow fast-moving streams; deep ponds protect beavers from predators, and give the animals underwater entrances to their dens in the stream bank.)

Ratliff said it’s not clear why beavers have only recently colonized the river through town in significant numbers. His theory is that the beaver population in the river outside the city limits has grown enough that young beavers are dispersing to less-crowded habitat.

In any case, Ratliff believes beavers can co-exist, in relative harmony, with people.

For one thing, beavers don’t as a rule stray far from the river; they’re not going to start gnawing at your home’s siding, for instance.When, as in Pearson’s case, beavers do munch on trees on private property, the solution – wrapping or fencing trees – is neither complicated nor especially costly.

“It’s really a neat opportunity to have urban wildlife,” Ratliff said.

Pearson agrees. He would, though, prefer that private property owners have more flexibility in dealing with beavers that cause damage. City ordinances prohibit residents from trapping or shooting beavers. State law prohibits residents from live-trapping beavers and moving them elsewhere.

Okay, now things are going to get REALLY unbelievable. Are you sitting down? I just want you to be ready for the shock, because it could trigger a heart attack or something. Take a deep breath, and think of it as a Disney movie. Sweet and a little too idyllic to believe. Ready?

Tom Fisk, the city’s street supervisor, said workers have had to move several beaver-chewed trees that fell across the Adler Parkway over the past few years.Crews used to haul the trees away, but recently they’ve just sawed the tree into chunks and spread the pieces along the river’s bank.

“We figured if we took away the tree the beavers would just take down another one,” Fisk said.

“It hasn’t been such a big problem that we’re looking at other options,” he said.Protecting trees with fencing, for instance, would hardly be practical, considering the river runs for more than two miles through town.

“There’s a lot of trees,” Fisk said.

What kind of groovy, laid back, reasonable town administrator says ‘well, there’s a lot of trees?’ Here in Martinez we held their feet to the fire for 10 years, were on fricking national news and on TV in the UK and our city manager is STILL ripping out the willow stakes we plant because he doesn’t want to encourage them.

Dear Suzanne, something tells me you’re going to do just FINE on this project. Baker’s going to celebrate beavers, children are going to learn and classrooms are going to thrive. Your creek will be filled with otters, frogs and heron. And heyy, maybe a Baker Beaver Festival is in your future soon?

One of the best parts about being forced to beg for beaver delights in the silent auction  is connecting with folks around the world whose hearts have been inexplicably touched by beavers. They created whatever they created because of this and they are delighted to meet another human in the world who’s worked for them too. They are inspired by our story, and I am reminded that good people exist in the world. It’s a perfect storm of goodness.

Capture4Case in point: MK Carving of Abbotsford British Columbia. He doesn’t even think he can donate because his pieces are usually custom made, but Mori Kono was so nice about  beavers and supportive of our work he gets a mention. And you will understand RIGHT AWAY why I wrote. He calls this enchanting piece “Oops!”.

Capture3How much do you wish you could climb these stairs every night? Who ever he made this for must lead an enchanted life. Come to think of it, we might actually know them. Do you think it was Glynnis Hood or Michael Runtz? Or maybe some evil executive for the Hudson Bay Company? I imagined whoever it was named their stair guardian. Do you think they pat every night on their way to bed? I’m pretty sure I would. I wrote him that I had thought I was so clever because when I made the ‘manger’ for my beaver creche I had amused myself by adding a few chew marks. I couldn’t believe someone else had the same idea and executed it so delightfully!

Beaverstock final logo 2016Another recent connection came from Castoro Cellars in Paso Robles. They had donated to us many times over the years, but had recently stopped which I was very sad about. I’m still on their mailer and I got the notice that their very popular “Beaverstock” concert extravaganza which had grown so much over the years had received a ‘cease and desist letter’ from the attorneys of the real “Woodstock” and they were told to change the name OR be sued.

Lawyers are good at making petty indignation seem threatening so they were looking for a new name. Hmmm, I mulled over the dilemma for a few moments and then broke into a grin. I immediately wrote the owner that there was only ONE sensible solution.

Instead of BeaverSTOCK call the concert BeaverSTICK!

The owner wrote back last night much amused and suffice it to say we get our donation. Thanks Castoro Cellars!

One of the artists who donated to the silent auction (Sara Aycock) sent tiny little business cards that were SO adorable I had to go see about designing our own. Turns out they are ‘mini’ cards designed by MOO, about half the size of a regular card. Right now you can design 100 for under 20 and chose a different back design for EVERY ONE. I ordered the cheapest kind just to see if I liked them.

cards So I picked four different designs with three each of Cheryl’s great photos on the back. They arrived yesterday and were AMAZING – but there was a mistake on the logo. I wrote them and they’re reissuing for free. Which means we have 100 adorable unusable business cards to use as an art project. Hmmm…

Now I’ve been trying to think up our Earth day art project and hadn’t yet hit on an inspiration. It’s the beavers 10th anniversary in Martinez and I wanted it to be special. But of course not too complicated for kids and volunteers and not to previewexpensive for us. And nothing we’ve already done before. I already came up with a giant card folks can sign wishing them Happy Anniversary. Wasn’t there something that could be done with these perfect little photos?

LOCKETS!!! Little photos of things you love go in LOCKETS!!! A little locket kids make themselves…and can wear on a string around their necks at the event so everyone can see them. One side could be a photo of our most beloved beavers (beautifully printed on card stock from my failed cards), and the other side should be a photo of something that represents Martinez….since the two are “Married” forever more…..

Beavers and Martinez…hmmm…(You know I considered a photo of the mayor just because I’m troublesome that way)….but I really wanted something more wholesome.

Something that represents Martinez…and it’s for an Earth day celebration at John Muir’s House….and he’s the greatest conservationist and beavers have been called the original conservationists….I think we have  a match made in heaven!16938893_10208977203533577_6242861908722332437_n

earthday locket

We even have all the supplies left over from other art projects! Glue sticks, scissors, card stock, string, and lovely keys to your heart. I’m so excited I’m wearing mine right now. This is the perfect way to say “Happy Anniversary” to our beavers. And its all because of a lucky mistake.

Which the beavers kind of are anyway.
