News of the environment or beavers impact on their ecology


Yesterday was a strangely successful day that turned out well for beavers. After writing about the Mystic lake madness I wrote the acting director of the Custer Gallatan Forest Service and some city folks protesting the decision to sit on this problem for three months and then expose the beavers to slow death. I was written back fairly promptly by that acting director saying the army corps of engineers had told them there was a risk of a 500-year flood event for the town below if the dam washed out. He assured me they knew about flow devices and would talk about this for the future, but had to do this now. The beavers would be trapped, not left to starve, which was something.

I was grimly comforted by this news, and mollified that he wrote back at all which I did not expect. He also said that he was back at his regular job now in Vermont and another ranger was in charge – whom he cc’d on the message so we could be in touch. I still thought the beavers were done for, but I was glad that my letter had been responded to.

45 minutes later I received this:

Update on Mystic Lake project.  Engineers are currently working on a mitigation device to keep water to tolerable level after lowering and keeping the beavers in the system.  Long term solutions will be discussed at a later date.  Thanks.

There must have been a lot of other public outcry besides mine. Maybe we’ll  never know. I will say I am capable of writing a fairly decent letter, but am downright talented at finding the right email address to target even when folks work hard to hide it. Still, I can count on one hand the number of times something like this happens. Maybe it has something to do with Amy’s recent presentation on the topic and my reminding the ranger of her skills and the fact that she was trained by the man who solved our beaver problem a decade ago? Maybe someone chained themselves to a bulldozer or threatened to stop dating the mayor’s niece. Who knows how these things work?

I’m just happy it did!

Dispersal: Elizabeth Saunders

To celebrate I started thinking about a festival design that would promote our new location and vaguely remembered a charming illustration by Elizabeth Saunders the artist who works with Cows and Fish. It was about beaver dispersal, but I thought it could easily be re-purposed to inspire Amelia on our brochure this year. Even as a starting place, I’m liking this a lot.

Today is full of blessings in every way! Louise Ramsay posted this on FB a very nice beaver program from radio 4. There are some irritating parts but stay patient because it gets very good. I especially find it kind of wonderful to hear how happily the reporter describes their return. Enjoy!

Another savory dish Rob Rich sent my way was this essay by author Ginny Battson. It is a splendid, thoughtful and thought-provoking read perfectly designed for a sunday afternoon by the seaside or a cup of coffee and the first snow in your uncle’s cabin. Which means it deserves much broader thinking than I can summon, but the beaver parts are really, really good so I’m going to share them.

Beavers are Fluminists

I learn from rivers, as do the beavers. I spend time in and around them, observing and sensing. Two and a half thousand years ago, the ancient philosopher Heraclitus also wrote on the profound things he learned from rivers. In an age before sHERCLITUScience, he looked for guiding principles in nature. What he found in rivers was a permanence in a reality of apparent change. All is flux, a matrix of matter and movement. The river is an analogy for an elemental cosmos, yet materially effervescent. Rivers are also life systems ~ complex and dynamic.

beaver swimmingBeavers, the river keepers, have evolved to be more than the sum of themselves. Beavers live in the life-flow, interrupt and send it in multiple directions. Known to ecologists as ‘keystone,’ First Nationers instead call them ‘sacred centres’ of the land. For they are whirling hubs of life-diffluence and life-confluence, integral to the flow just as mind cannot be separated from body. They are dam and bridge builders, storing water at times of plenty for times of drought. They sequester carbon kit chewing over beautiful waterby trapping it in fluvial muds that eventually become rich soils. They are coppicers; the trees they fell to feed upon and rear their young will regenerate, beaver-cuts catalysing a diversity of plant and animal life. They are also wildlife protectors ~ during winter, woody debris left trapped behind dams are buried beneath deep snow, and provide shelter for a host of smaller mammals and reptiles during the bitter cold. And then, when the northern hemisphere tips nearer to the Sun, melt water forms reservoirs and a rising water table, creating habitat for amphibians and a plethora of bird species, including waterfowl ~ wood duck and heron, migratory waders and passerines. New lentic deeps amongst woody debris provide fish fry safe passage to grow to adulthood. Majestic osprey take the adults. In lotic flows downstream, clouds of black fly larvae lay submerged, attached toNorth American Beaver Castor canadensis Martinez, CA substrate with silk, to emerge in spring and breed, then feed the bats that hunt on the wing above the beaver-cuts. The dams may eventually blow-out by flood, and the beavers will find new territory. Upstream, moose rear youngon regenerating meadow grasses years after dams are abandoned. This really is rich habitat; the smell of river, wood and beaver is intoxicating.

If beavers could speak human, they may also say: Into the same rivers we step and do not step, we are and are not.

(Heraclitus Homericus B49a)

Ginny introduces the word Fluminism to explain the interconnected dynamics of the universe flowing forwards, connecting and enriching  and says it’s what beavers do best. She even goes so far as to call it a kind of love, or the doing and caring parts of loving. Her essay is filled with the richest imagery and most fluid prose. You should really tuck away the link and read it sometime when you have time to reflect. For now I will just say that she GETS beavers. I remember Skip Lisle similarly said the principal of beavers is dynamism, meaning change. They change things, things change them, the things that are changed by them change other things. Maybe after 10 years of watching beavers I can see how they changed me, how my life has rearranged itself because of their work.

Back to the Maine woods, and it’s getting late. I’m a little bit edgy because the light is falling. As I hurry back with my baby over the bridge towards Gilbert, we hear the slap of a scaly, flat tail hitting the water ~ splash. I stop and turn us around to follow the sound. My eyes adjust to the watery scene. And there is the beaver, Fluminist, swimming, with a wet, brown head visible for a moment and shiny eyes, before diving beneath the inky reflections of a darkening sky. She’s warning others we are here. Though we’d never harm her, others might. I feel at peace knowing she is here, knowing she has a rich intrinsically valuable life, full of love for this world in the river she understands so intimately. I point her out to my baby who instinctively feels both the joy and excitement. Formative moments, for sure. There is so much yet to learn from Ahmik, Fluminist, and I walk us home full of awe and gratitude.

CaptureNot too long ago Rachel Hofman of the NWF magazine in Vermont contacted me about an event they were co-sponsoring with the Clark Fork Coalition in Montana about the benefits of beavers. She was working on a flyer to promote the event and wanted to use a few of Cheryl’s great photos to do so. The talk would be given on October 25th by Amy Chadwick, who is also a friend of ours.

It sounded like a fine cause, and it reminded me I hadn’t seen that particular photo in a while, so Cheryl gave consent and then we pretty much forgot about it because not long after our exchange the entire napa-sonoma valley erupted in flames and that held our attention for a while. Yesterday I was reminded of it by reader Rob Rich who sent me some great information they put out on beavers. It reminded me that I had forgotten to share it, so enjoy!

Beavers – Nuisances or Watershed Heroes?

For CFC’s inaugural Beaver Month we chatted with Andrew Jakes, Regional Wildlife Biologist for National Wildlife Federation about the unsung bucktooth heroes of the watershed – the beaver.

Why are beavers considered ecosystem engineers?

Beavers aren’t just considered ecosystem engineers…beavers are THE quintessential ecosystem engineer! They change a landscape like no other species in the world, besides humans. They change the landscape to suit their needs, and when they do that, it turns out that they change a lot of other things too.

OK, so what else changes in the landscape when beavers are present and building dams?

So much! When beavers show up, a lot starts to change. Studies have shown that beaver dams change everything in the system; from soil to vegetation to water quality to wildlife. It’s hard to sum up in only a few sentences, but I’ll do my best to give you a summary…

First of all, beaver dams slow the flow of water. This means water is on the landscape for longer. This can cause the floodplain to expand, soil structure to change, and the water table to rise. All of this also means that riparian vegetation can thrive. This means extra foraging opportunities for beavers and other creatures, so more wildlife starts to frequent the area. It’s no secret that wetlands are beneficial to the ecosystem, and beavers are little wetland creators.

The bottom line of all this is that when a beaver dam shows up, we see an increase in biodiversity, which thereby means the ecosystem becomes more resilient.

You can read the rest of it the fine story here.  The entire ‘beaver appreciation month’ concluded with the talk by Amy Chadwick at a local pub in Missoula on Thursday evening. Obviously convincing the land owners of Montana to coexist with beavers takes the best and the brightest, and Amy (who worked with Skip Lisle) is well up to the task.

Walk and Talk: Busting Beaver Myths

During the month of October, the Clark Fork Coalition is putting a spotlight on the hard-working, fur-ball hero of the watershed – the beaver.  Join the Clark Fork Coalition and Ecologist Amy Chadwick for an evening of natural history and cutting-edge restoration featuring beavers and beaver mimicry. Chadwick is an Ecologist at Great West Engineering and the chair of the Montana Beaver Workgroup. Amy has been working in stream and wetland ecosystem assessment and restoration in Montana for 20 years, but in recent years her work has focused primarily on beaver habitat restoration and improving natural water storage.

Amy will share facts of about beaver ecology, review how beaver act as ‘ecosystem engineers’ in western watersheds, and share the implications lost beaver habitats on our water budget.  Chadwick will be joined by Andrew Jakes, Wildlife Biologist with the National Wildlife Federation for a discussion of beaver habitat recovery work underway in the Upper Clark Fork and a Q & A session.

Don’t you wish you were there listening to Amy’s talk? I met her at the Beaver Conference in 2013 and we have kept in touch over the years when beaver issues arose over the years. She worked with Skip installing flow devices in the area for a while and now carries on the work bravely on her own. It’s wonderful to see folks like Amy and the Clark Fork Coalition working in their own backyard to make way for beavers and teaching others about their benefit to the environment. I hope the beaver night was a resounding success and I hope NWF thinks of us first when they have a beaver event to promote in the future!


There’s a nice story this morning about watching beaver activity as we head towards winter from Marshall Helmberger of Minnesota.

The busy season

It’s the busy season at our neighborhood beaver pond, as the locals prepare for the impending season of scarcity. The signs of activity are everywhere, particularly along the pond’s edges, where the resident beavers have recently felled at least a couple dozen youngish aspen to put away for the winter.

It all seems pretty familiar. We fill our own wood sheds and stock the pantry and freezer with the season’s produce, and the beavers do pretty much the same. This time of year, the beavers are cutting aspen and willow and storing the branches and smaller trunks in a huge cache under the water, just outside one of their two lodges. These caches are readily visible this time of year— since some of the smaller limbs often stick out from the water— and are an easy way to tell if beavers are planning to spend the winter in any given lodge. Beaver lodges can last for decades and they can fall in and out of use over the years, so this time of year I always look for the telltale signs of a fully-stocked pantry to determine if a lodge is currently active.

Once the ice arrives on the beaver pond, which could happen this coming week given our recent cool down, the beavers will be locked in for the winter. They’ll live the next several months within their dark lodge, only occasionally venturing out of one of their underwater exits to grab a bite. While their pantry of sticks is their primary source of winter food, they also store large amounts of fat in their tails this time of year, which they will also rely on during the winter months. A beaver’s tail, in the fall, is usually substantially larger that it will be when the beavers emerge from their lodges next April or May.

Don’t you wonder what that’s like? Or which family member you like enough to be stuck in a closet with for three months out of the year? I’ve been fairly lucky in terms of opportunities to see beavers, but I will always regret not getting to see this. The tell tale food stash and the signs of beavers cracking through the ice to get whatever they can forage. I’m not entirely sure I believe the last sentence about their tails being smaller in May, but I bet our beaver size has a lot to do with not needing to live off reserves. Marshall does a nice job in this piece by capturing the urgency of late fall.

Speaking of beaver authors, I heard from author Ben Goldfarb that he just had a very enlightening chat with our city council man Mark Ross about the beaver story. He said it was helpful to get the city perspective on the story.  (I would just LOVE to be a fly on the wall for that conversation, wouldn’t you?) I bet there were lots of fears of flooding and very few honest concern about voters in his tale.

Meanwhile it you want to get the story from the other perspective, why not listen to the talk I did Tuesday from the convenience of your desktop. I really appreciate fur-bearer defenders for getting this online and sending me the link! This will give the whole story plus some never before disclosed secrets from behind the scenes. (You can thank them for doing tall his by dropping 5$ in their donation jar.) I just realized that the anniversary of that big November meeting is a week after halloween! Perfect timing to hear it all again or for the first time. I think my voices sounds lower, what do you think?


Whew, I was relieved to hear that Mike Callahan (whose WIFE is a trapper) had never heard about using a cross-bow either to shoot unwanted beavers either. So that means this is just a one-off until we hear otherwise. (A horrible one-off but better than  a common occurrence.)

Meanwhile, I received a note from author Ben Goldfarb yesterday that his writing retreat is going well and that he will have the first draft of his beaver book in November! How exciting! And I heard from Tom Rusert that their home didn’t burn down, their beloved bulldog Daisy is recovering from smoke inhalation, and things are moving forward.  There was an excellent article in the East Bay Times and Fire Rescue about our good friend Luigi feeding the first responders last week, which surprises me not at all. That man has been incredibly community-oriented since before he even had a community.

Calif. deli owner feeds first responders in Calif. wildfires Capture

MARTINEZ, Calif. —Luigi Daberdaku has been making sandwiches at his downtown deli for years, but never this many all at once.

Since Thursday, there’s been an assembly line set up in his shop, right near the shelves with the specialty sodas. “Cutting the meat, cheese, lettuce, onions, cucumbers, I need volunteers… plus I need more meat; we ran out of meat today after 275 sandwiches,” Daberdaku said Monday.

By that afternoon, as he prepared to make his fifth delivery trip, he and his assembled teams had made almost 1,500 sandwiches. It started Thursday, Oct. 12, when he and volunteers made 150 sandwiches by midday. He took them to Fairfield that first day for further distribution; since then, he has gone straight to the hard-hit areas, mostly in Napa, himself.

Dear, sweet Luigi, you deserve all the credit you get. I recall he had barely set up shop downtown at the November 2007 beaver meeting ten years ago, when he stood up with his very thick Albanian accent and said “When I first come to Martinez there was no one downtown. It was like a ghost town! And now that the beavers have come there are many, many people every day!” He has been our friend since the beginning, and his wonderful daughter Louisa planted trees, worked the festival and brought us sandwiches every year.  Helping first responders is just the kind of thing he’d do.

(Let’s hope that sweet steady rain we got last night helped them too.)

Yesterday the National Geographic Blog called Cool Green Science decided that beavers deserve a little credit also. Of course they couldn’t resist reminiscing on Idaho throwing them from planes – but this is a pretty nice summary. Watch the video all the way through.

Restoring Beavers by Plane and Automobile

“Beavers are really nature’s engineers and they do a really good job at what they do,” says James Brower, Idaho Department of Fish and Game volunteer services coordinator. “We love beaver and we love what beaver do.”

“We really want them to set up shop and transform that habitat and make it a little better for everything,” Brower says. “Beaver create habitat for not only fish but also for deer, elk, moose and bear. Pretty much everything needs water and places to drink. There’s no doubt in my mind this benefits everybody.”

I like what Mr. Brower has to say. I think I will try and make contact. But I’m never a fan of the beaver-flinging story – as I’m sure you all know by now.
