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

Category: Who’s saving beavers now?


Well what do you know, folks are finally getting around to opening the memo on beaver benefits to trout. Do you think this came as a shock? Now I dearly wish this had been reported in Wisconsin, but hey, North Carolina isn’t bad either.

Beaver ponds actually keep the water cooler, study says

Now scientists and conservationists realize that beavers and the dams they make across streams have a lot of benefits. Most recently a study showed that the big pools of water backed up by beaver dams actually help keep the water cool, and cool water is important to a lot of different types of fish like native trout, steelhead and salmon.

To figure this out, scientists built fake beaver dams and recorded the water temperatures. Although it would seem like a pool of slow-moving water would get warmer, this study found that the water actually was cooler. Why would that be? One reason was there was more and deeper water backed up by the dams. What’s more, the big pools of water seem to help feed water that’s in the ground which also circulates back to the surface, keeping the creeks cool.

Knowing that beavers can play an important role in nature, humans are now putting beavers back in wild places. The Forest Service hauled beavers on horseback into Buffalo Fork Creek, which flows into Yellowstone National Park’s Lamar River. Idaho game biologists dropped parachuted beaver in cages into a remote wilderness area in the 1950s.


Lot’s of generous gifts this week. Starting with a wonderful collection of puppets from Folkmanis which include some delightful hedgehogs, an english badger, a wild-toothed crocodile and a delightfully soft white dog. Thank you a million times over puppet wizards for supporting our beavers since the very, very beginning.

And a wonderful donation from San Francisco author Mary Ellen Hannibal with a fine copy of her recent book where people like us do remarkable things for wildlife.

For me the most compelling reason to do citizen science is the sixth mass extinction of plants and animals currently underway.  In the book I do a lot of reporting and research on this scourge, but contextualize what’s happening within a broad framework. “Extreme citizen science” often focuses on indigenous traditions for caring for the land, and I learn a great deal from the Amah Mutsun tribal band.  I take great inspiration from three literary figures who contributed to citizen science—John Steinbeck, Ed Ricketts, and Joseph Campbell.  While the hero’s journey as discerned by Campbell needs updating for dealing with today’s global issues, he still provides a model for aggregating individual efforts on behalf of nature to achieve collective impact.  That’s the job of the citizen scientist.”

The book is signed. Mary has also been a supporter of the Martinez Beavers since the beginning, and I am grateful that she will continue to encourage citizen science by donating it for the festival.

Of course the beaver problem isn’t extinction, it’s depredation. But I’m sure she’s working on that book next. Thanks Mary!


Finishing the Last of the Mohican’s last night, I thought of my own dad with this quote by the affable, skilled and boyishly cheerful Hawkeye,

“Think of me sometimes when on a lucky trail, and depend on it, boy, whether there be one heaven or two, there is a path in the other world by which honest men may come together again.”Father daughter dinner


Some days I just can’t keep up with the hot number of good news stories reported about beavers. I’m already over the moon because Jon picked up the generous puppet donation from Folkmanis yesterday and we received our posters back from the printer. Didn’t this illustration of Alex Riley’s quote, my design and  Coyote Brush Studios‘ beautiful artwork turn out extraordinary?

The plan is to sell these at the festival and by mail, although we haven’t settled on a price yet and technically they’ll be thank you gifts for donations, not sales! They are 18 x 24 and would make a wonderful classroom or visitor’s center poster!

As if that wasn’t exciting enough, this morning there’s a fantastic story out of Alberta about the always inspiring Cows and Fish teaming up with the Miistakis institute to undertake a massive survey an beaver education project, to learn how best approach the landowners.

Is Canada’s national animal a boon or a pest?

Beavers: love them, hate them or ambivalent?

A recently launched survey seeks to learn Alberta landowners’ attitudes about one of Canada’s national symbols. Alberta’s Cows and Fish society has partnered with the Miistakis Institute, a non-profit research group associated with Mount Royal University, on a survey to assess landowners’ knowledge and perception about beavers, their habitat and their management.

There are benefits and drawbacks to having beavers on the property, and survey results will be used to further develop education and outreach on the role of beavers in the ecosystem.

Beavers are a really important keystone species in our ecosystems and they provide some really critical function within our watersheds, and people don’t know a lot of that,”said Miistakis executive director Danah Duke. “We recognize that beavers cause a lot of damage. They take down trees, they flood areas. We recognize that and we recognize that in order for people to be able to coexist with beavers, we need to be able to manage beavers.”

Duke said she suspects many people don’t realize all the benefits beavers provide, such as raising the water table, slowing stream flow, creating habitat for biological diversity and making stopgaps against drought.

“Beaver ponds retain water 50 percent longer than stream sections with no beaver activity, so in times when water is scarce, we find places that have beavers and beaver ponds, water stays on the landscape longer.”

Anyone in Alberta is welcome to take the survey, but the project is aimed at southern Alberta for the moment, said Duke. Organizers are hoping to receive at least 400 responses so that they have statistically significant results.

I am so beyond impressed with the good work Cows and Fish is doing and has been doing since long before Martinez started to play. You can check out the great survey here, I was already their outlier this morning. It’s well done and obviously sneaks in a little education at the same time as it asks questions. Just check out this question which must come as close as a beaver survey can to being a push-poll.

push pollI sure hope during their data analysis they recognize me and wave hello!

A final burst of good news just came from author Ben Goldfarb who is writing the newest book on beavers. He just found out he is the winner of the Aldo Leopold Mi Casita fellowship which means he gets to write his book at Leopold’s home in Taos. It’s a huge honor and beavers and Ben couldn’t deserve it more.

Leopold’s ‘Mi Casita’ residents focus on environment projects

Wolves, beavers and the land ethic are the areas of interest for this year’s participants in the Aldo and Estella Leopold Residency Program, which is now in its fifth year. The residents will spend a month in late summer at the Leopolds’ first home located on U.S. Forest Service land in Tres Piedras.

Ben Goldfarb, a science and environment writer from New Haven, Connecticut, will continue working on a book project about the ecological and hydrological benefits of North American beaver restoration.

In fall 1912, Aldo Leopold, then the newly appointed supervisor of the Carson National Forest, married Estella Luna Otero Bergere, a prominent daughter of Santa Fe. They moved into their new house, called “Mi Casita.”

It was at Mi Casita that Aldo Leopold found his footing as a leader in forestry and conservation. He once described conservation as “the slow and laborious unfolding of a new relationship between people and land.”

The U.S. Forest Service restored the Leopold house in 2007 and has joined with other residency partners to make it available for the Aldo and Estella Leopold Residency Program.

The sponsors of the residency program aimed to promote a transformative “unfolding” by inviting conservation-minded writers, artists, teachers, professionals and practitioners to Mi Casita. Each resident receives a stipend of $500 to help defray travel and living expenses.

Ben says the residence committee was certain Aldo would approve, and we of course agree. He notes that Aldo’s son Luna who wrote so much about fluvial geomorpology never mentioned beavers. But here’s a secret fun fact. Luna was the dissertation chair of Ann Riley who’s recent book on restoring neighborhood streams has a chapter on the Martinez Beavers.

So I think this was all meant to be, don’t you?


More good news for beavers. This time from our own Mt. Diablo Audubon, where we’re a lead story in their newsletter the quail and a the top ‘community event’.

More news is that I was notified by Dr. Duncan Haley that they are offering a Ph.D. candidate paid position at the University College of Southeast Norway in functional  ecology. He wanted to make sure we passed this along in case any of you beaver scholars were sufficiently tempted. You can go read about it here:  Duncan also notes

In Norway PhD students get paid properly – the pay code translates to 436 900kr/year or c. 51 500USD. For US citizens there is also an amazing tax treaty provision, which applied to Rachel Malison when she did her beaver/fish postdoc here. She didn’t have to pay income tax to anyone, US or Norway. Plus you get a year off on full pay if you have a baby and other social benefits. Please circulate.

And it’s not like the science positions in the US will be doing much for the next four years, right? You might get to see the Northern lights!  Norway is a beautiful country. Take a look.


Yesterday was a VERY good day. We had three thrilling pieces of very good news, consisting of 1) for the very first time we get a US Forest Service exhibit at the festival which we never did before, 2) that the Alhambra Valley Band is confirmed in some variation, and 3) that Brock Dolman is going to appear in beaver costume to talk about beaver benefits on stage. I am so happy when things fall into place that I start looking immediately on the horizon for the dark cloud (or piano) that will inevitably follow.

But things are going in the right direction. I’m definitely happy for that.

Meanwhile, in the world of false beaver accusations,  cranky old men are still saying crazy things about beavers, just in case you were curious.

Critter built impoundment beneath railroad bridge spurs Tom McDonald to action.

Over time, he sold most of the 11 acres. Other developers created the Portland Fairview RV Park, and a cozy cluster of single-family homes sprung up around Palisade Drive, Heartwood Circle and other residential streets. McDonald owns just a sliver of land between the RV park and Northeast 217th Court. Fairview Creek runs right through the tract, and Union Pacific’s railroad trestle is just a stone’s throw away.

That’s where the problems began, and McDonald had what he described as a “Holy cripes!” moment.

“We were out talking (and) walking around, and beavers were popping up around our feet,” McDonald relates. “They put a delay on our deal because it was so wet.”

During the prep period before any sale was possible, McDonald discovered that his land had experienced some heavy flooding. The culprit appeared to be an industrious beaver clan that had built a 6-foot-tall dam across Fairview Creek under the railroad bridge. While the Multnomah County Drainage District No. 1 could technically lower the waterline at Fairview Lake, this wouldn’t remove the dam or solve the long-term problem with flooding.

“Looking at the situation from a layman’s view, it appears that area is ‘honeycombed’ with beaver burrowing,” McDonald said.

annex-keaton-buster-general-the_06[1]Because you know how beavers like to burrow in wetlands. Dig Dig Dig, that’s what beavers do. And destroy train trestles, like in those silent movies.

Honestly, is the crazyoldmanvan coming for you soon? I mean what would be the POINT of a beaver digging in flooded banks? They obviously aren’t making a lodge inside them. Now I suppose they theoretically could be making a canal to drag supplies through, but do you honestly think the metal and cement pilings and steel girders of the modern train trestle are going to be troubled by a bunch of beavers?

I’m a little doubtful about the 6 foot dam myself. I mean our dam was assessed by PWA  once as 7 feet tall but that was because they were lying and measuring with sticks of terror.  You can tell it’s not 7 feet tall because the man in the front filming is Moses Silva of sturdy Mayan frame and just over 5 feet. Assuming his mystery dam was as high as ours that means those beavers had a lot of resources to choose from.

Looking at this it’s kind of amazing to think that mom and Dad made this whole thing by themselves back then, because there were no yearlings to help.

Now I’m officially looking forward to our summer lineup. Here’s Brock as Buster Beaver at the Daily Acts breakfast in Sonoma in 2014.


Vermont is leading the way again, look what they’re doing now:

‘Beaver Baffles’ Prevent Flooding and Resolve Beaver-Human Conflicts

BOLTON and RICHMOND, Vt. – To prevent flooding on nearby roads, the Vermont Fish & Wildlife Department recently completed several water control devices on beaver dams in Bolton and Richmond. Known as ‘beaver baffles’ these devices confuse beavers by using a large plastic tube to create a hidden breech upstream away from the beavers’ dam.

The Fish & Wildlife Department expects to install more than a dozen additional beaver baffles throughout the state this year. The baffles are one of many techniques that department staff employ or recommend to landowners to minimize beaver damage to property or trees. Other techniques include using culvert fences or placing wire mesh or special paint around the base of trees.

“The wetlands that beavers create provide habitat for a variety of wildlife such as waterfowl, songbirds, frogs, turtles, and otters. These areas can also absorb extra water during rain events and clean pollutants from water, so we work hard to preserve these wetlands whenever possible,” said Chris Bernier, wildlife biologist for the Vermont Fish & Wildlife Department.

You know what I wonder? What kind of leadership is necessary to make it so your state Fish and Game agency actually spends time and money installing flow devices. I mean is it a top down kind of excellent governor thing? Or is it a bottom up kind of informed biologist who teaches all the others? Of course I wonder how can we get that kind of response going here? I’m pretty sure our fish and games days are filled with paperwork and occasional license stops. But I could be wrong.

The Vermont Fish & Wildlife Department has installed 291 beaver baffles in Vermont since the program started in 2000.

“We receive roughly 200 beaver complaints a year,” said Bernier. “Several staff members respond to these complaints, and one technician is dedicated solely to addressing beaver conflicts from spring through fall. Despite these efforts, other management techniques must be used. We also rely on regulated, in-season trapping to maintain a stable beaver population so Vermonters continue to view beavers as a valued member of the local ecosystem and not as a nuisance.”

Do you think it’s the influence of famous Vermonter Skip Lisle that eventually just rubbed off on them? What ever it is I like it. 291 sounds like a lot, but that’s like 17 flow devices a year. How do you think they decide which site gets an install and which one gets permission to trap?

Now we’re headed northwest to British Columbia where folks are interested in letting beavers help frogs.

Green Beat: Leave it to beaver

Monica Pearson is on a mission to bring back the frogs.

Our region was formerly a better place for frogs because wetlands were more abundant. Many wetlands have been lost to development and farmland like the 11,000 acre Sumas Lake that was drained in the 1920s.This project was proposed by the Vancouver Aquarium and Earth Rangers, who raised over $75,000 to help save the Oregon Spotted Frog. We identified a field where the historic wetland had been drained for agriculture but wasn’t in use any more because it was still too wet in Metro Vancouver’s Aldergrove Regional Park.

“Our goal was to learn about restoring a shallow marsh wetland specifically for Oregon Spotted Frogs, despite the presence of invasive Reed Canarygrass and American Bullfrogs. Research that I did a few years ago suggested that keeping a marsh shallower than 30 cm would be good for Spotties, and bad for Bullies, but it’s also great for invasive Reed Canary Grass, which we don’t want.

“When building a wetland, you need to be aware of your water budget. We weren’t cerfrogtain that there would be enough to keep the wetland wet all year long, especially in a long summer drought. We expected that much of the wetland would dry up through the summer but less than two years after we had built the wetland in 2013, we discovered that the wetland was not only holding water year round, but actually getting deeper.

“Why? Beavers! Through some truly impressive engineering, some local beavers first plugged up drainage ditches, then re-routed water into those ditches from a nearby stream, and were filling it from the bottom. It was like filling a bathtub from the drain.

The result was stable water levels through the whole year — a much better outcome than we ever expected! There are over 100 bird species using the site, dragonflies, fish and many native frog species breeding in the wetland.

The surprise intervention of beavers in Monica’s project is encouraging in an age when so often our goals for rehabilitating nature seem out of reach, and we forget that creation itself might be able to lend a hand — or at least a paw.

Apparently Monica was surprised that beavers build such remarkable wetlands. They made the water deeper than her project needed and the article said they have to ‘manage’ it somehow. I hope not stupidly. But in the meantime I’m really glad that folks were reminded how much beavers help frogs.

There was a ton of beaver news yesterday, but I’m going to leave you without talking about the WETLAND WAR in Narvan just yet, because I’m headed to Marin tonight to sprinkle beaver gospel upon them and want to rush off to make some coffee before settling in to watch the Comey testimony. I’m pretty sure beavers won’t come up, but who knows?
