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

Month: July 2018


If you had to pick a single paper in the nation that features the most accurate beaver stories, you would be hard pressed to find one more engaging and reliable than the Brattleboro Reformer in Vermont. They were the first ones to cover the lovely, intimate field notes of Patti Smith who went on to author the Beavers of Popples pond, and they are always quick on the draw to follow the important work of Skip Lisle.

Now they are fielding Ben Goldfarb’s book which talks about their 0wn homegrown hero.

Nature’s Carpenters

Resourceful rodents create entire ecosystems

Grafton resident Skip Lisle, a beaver expert, shows off a newer version of his beaver deceiver.

GRAFTON — In the 1960s, if you lived in Vermont, you had to go to a zoo to see a beaver.

Not any more.

Author Ben Goldfarb, whose book “Eager: The Surprising, Secret Life of Beavers and Why They Matter” was published last month by Chelsea Green Press of White River Junction, was in Grafton Friday afternoon to meet up with one of the subjects of his book: Skip Lisle of Grafton and Beaver Deceivers International.

“We want beavers to keep creating wetlands,” said Lisle, who Goldfarb describes in his book as “the world’s foremost castorid conflict mediator.”

Translation: Lisle knows a lot about helping beavers co-exist with humans and avoiding fatal wildlife conflicts.

Lisle earned his place in Goldfarb’s book by inventing the anti-trap: a wire and wood device that he calls the ‘beaver deceiver’ that keeps road culverts free and flowing.

Lisle said when he was a kid, his parents took him to a New Hampshire wildlife zoo to see a beaver.

That certainly isn’t the case in 2018, as Lisle’s corner of Grafton has a thriving beaver community, and according to Lisle, all forms of wildlife are thriving thanks to the beavers.

The wetland was full of vibrant wildflowers, birds flitted from touch-me-not to touch-me-not, the concentric circles from rising fish dotted the wetland, and countless songbirds flitted constantly. Wood ducks, Canada geese and hooded mergansers also made the large pond home. Before the beavers, Lisle said, it was a field.

“Now it’s just teeming with life,” he said, to the plunking of wood frogs and a chorus of birdsong.

It’s Martinez hero and our old friend Skip Lisle! Hi Skip! And hey look Ben Goldfarb is right beside him! Wasnt he just here at the beaver festival? It’s amazing when you think about it how many beaver paths go through Martinez.


Environmental journalist Ben Goldfarb visits Grafton resident Skip Lisle, a beaver expert, during a book tour for Goldfarb’s book “Eager” on Friday, July 20, 2018.

Lisle, a wildlife biologist by training, said he wishes flow devices would be accepted and put into use to save more beavers.

He said he built his first deceiver out of his father’s garden fencing.

He travels all over New England installing the ‘deceivers,” which are wire contraptions built around culverts or other drainage pipes and which prevent the beavers from damming the culverts. In essence, the ‘deceivers’ create permanent leaks in a beaver’s dam, allowing water to drain at a slow rate and thus avoid the ire of highway engineers and public works directors.

“He’s a pretty big figure in the beaver community,” Goldfarb said of Lisle.

Goldfarb, an environmental writer whose work has appeared in Mother Jones and Audubon Magazine, as well as High Country News, recently moved from Northhampton, Mass., to Spokane, Wash. He and Lisle acted like old friends. They share a devotion to the sleek, nocturnal mammal and its pivotal role in the environment. Goldfarb, like Lisle, is a ‘beaver believer.’

To Lisle and Goldfarb, it is nothing short of murder the practice in which some state highway departments and road foremen trap and kill beavers rather than find a way to co-exist and prevent damage to roads and other infrastructure.

Beavers have played an even more important role out West in creating wetlands and restoring some of the ecological balance, and co-existing with cattle grazing.

Goldfarb was on his way to Manchester for a book signing event at the Northshire Bookstore. He has traveled all over the United States and even to Scotland to research and write his book, which was commissioned by Chelsea Green.

Do you think a beaver book has ever made a bigger splash? Even though there was a flurry of press around Glynnis Hood’s book debut and Francis Backhouse still gets good coverage, I never saw anything like this sustained, cross country beaver benefits tour. I don’t even want to think about how depressed I’m going to be when this is over. Carpe Diem!

Beaver dams do pose flood risks, he said, but they are also “forces of flood mitigation.”

“I’ve been battling this for 25 years,” said Lisle, who said he has hopes that Goldfarb’s book will open people’s eyes to the importance of the beaver.

It’s wonderful to see Skip get ‘founding father’ status. He should. And it’s great to see yet another persuasive voice for Ben’s book.  Aren’t you curious how it’s doing already in sales? Well, it’s off to a bang up start, that’s for sure. Ben’s book is headed to the Washington Post this weekend and booked locally for Terra Vera KPFA radio on friday. Where, as it turns out, I will also be serving in a minor role discussing the historical California conundrum. So far I don’t get the impression the host doesn’t seem to like me very much so I’m expecting to be mostly ignored, but who knows? 


At this point you might be asking yourself “Is there any beaver news in the world that’s not about Ben Goldfarb’s book?”. And of course there is, so settle in because yesterday was a beaver bonanza day as they released beavers in to Forest Dean in England to help with flooding and biodiversity. It took my English husband forever to pinpoint that the Forest of Dean was North of Devon on the edge of the west coast before Wales. Everyone – and I mean EVERYONE – covered it, the local papers, the national papers, the news. If an entire nation didn’t just hear that beavers help flooding I’d be very surprised.

Let’s go with a nice respectable paper like the Guardian.

Beavers released in Forest of Dean as solution to flooding

Four hundred years after the beaver was hunted to extinction in the UK, two of the mammals have been reintroduced on government land in an English forest as part of a scheme to assess whether they could be a solution to flooding.

Two Eurasian beavers were released on Tuesday into their new lodge within a large penned-off section of the Forest of Dean in Gloucestershire. The hope is that the animals will build dams and create ponds on Greathough Brook, which feeds into the River Wye, and slow the flow of water through the steep-sided, wooded valley at times of torrential rainfall.

In 2012 the villages of Lydbrook and Upper Lydbrook were badly flooded. Hundreds of thousands of pounds has been spent on conventional schemes such as replacing drains to try to keep the communities dry and safe.

The government hopes that introducing the beavers into a 6.5-hectare (16-acre) enclosure on Forestry Commission land will help hold back the waters in a more natural way and improve biodiversity.

This comes straight from the top, the secretary of the environment Michael Grove. So it’s important to realize the significance. Of course they haven’t yet decided the niceties of whether of not the beavers have a protected status in the UK or not – but heck why worry about the little niggling details?

Rebecca Wilson, the head of planning and environment for the Forestry Commission in west England, said: “Beavers are natural habitat engineers, restoring complex wetland habitats and providing habitat for declining species whilst slowing the flow of water downstream.”

As well as having the potential to ease flooding, the beavers may also improve the habitat for other flora and fauna. Greathough Brook was once home to thriving populations of water vole, glow-worms and wood white and pearl-bordered fritillary butterflies, but they have vanished as the trees have blocked out much of the light. The beavers are expected to harvest some of the timber, which could improve the habitat for other species.

Well, that’s nice. Yeah beavers! And yeah ministry of the environment.

Can you imagine some day our secretary of the interior saying beavers benefit the environment? What am I saying. That could never happen. He’s too busy selling off assets. But this is a great article.

I confess I actually get worried when I see headlines like “Beavers prevent flooding” for the same reason we avoid headlines like “eating kale prevents cancer”. We want the word helps in there somewhere, because nothing is guaranteed and two beavers can’t change the climate on their own, Oh and parts of this paragraph was a concern.

Officials emphasized that the beavers had been tested for disease and a management plan was in place to make sure the enclosure remains secure. They also stressed that the beavers do not eat fish and would not stray more than 30 metres (100ft) from freshwater.

Um……about not leaving the water….ah well never mind.


Acting as unofficial beaver secretary during this wild and glorious renaissance period is truly a full-time job. I can barely keep up with the latest news and my beaver ‘to-do’ list is getting longer and longer. Never mind, it’s a wonderful problem to have. Let’s turn our attention to the big guns where Sarah Boon yesterday reviewed Ben Goldfarb’s book for Science Magazine.

Recognizing their role in maintaining healthy watersheds, “beaver believers” work to rehab the rodent’s reputation

Why should we care about beavers? Consider all they do. Beavers convert vegetation to marsh to wetland and back again. They facilitate water storage in ponds and recharge groundwater. Ponds and meadows sculpted by beavers concentrate nutrients such as nitrogen and phosphorus. Not only does this create fertile ground, it helps filter agricultural runoff. Beaver-dammed landscapes create habitats for other species, and their complexes can serve as wildfire breaks.

Beavers still face obstacles when we attempt to reintroduce them into ecosystems in which they once flourished. Predators can eat a beaver for lunch, while cattle grazing removes vegetation and can alter a stream’s configuration in such a way that it can no longer support beaver populations.

Eager also highlights the problems of preconceived assumptions about beavers and beaver management. A common supposition among fish ecologists, for example, is that beavers are bad for salmon because their dams prevent the fish from swimming upstream. However, Goldfarb cites a comprehensive review of 108 papers that showed that beavers benefit fish populations more often than they cause negative consequences.

We’re coming to my FAVORITE part. Pay close attention.

A more egregious error occurred in California in 1937, when ecologist Joseph Grinnell declared that beavers had never inhabited large portions of the state. Although this was untrue, it went unchallenged and affected beaver recovery and ecosystem management across the state until it was disproven in 2012.

DISPROVEN! DISPROVEN! I can’t tell you how joyful it makes my heart to read those words in Science-frickin-magazine of all places! I love the idea that we changed the accepted lore about beavers forever and ever.  So that our painstaking findings and hours pouring over microfilm archives just get casually tossed out in the middle of this article like saying ‘it turns out the earth isn’t flat’.

I have a second favorite part. I admit. It’s here.

Goldfarb speaks largely with “beaver believers”—individuals who try to help humans and beavers coexist by mitigating the impact of beavers on the built landscape and by reintroducing them into stream systems that they can potentially restore. He lets his interviewees tell the majority of the story, recalling, for example, Councilman Mark Ross’s interaction with a local businessman during a tense meeting of pro- and anti-beaver groups in Martinez, California (“‘This seventy-year-old guy is about to hit me! …Do I hit back against a senior citizen or not?’”)

hahahahahahahahahahaha Martinez infighting in science magazine! Is there anything more lovely to behold? I rushed straight to the mailbox to look for my thank you note from the mayor, but I’m sure it just got delayed. Because honestly, what city wouldn’t be proud to be included?

Goldfarb ends the book with a trip to the United Kingdom, where beavers haven’t been seen since the 17th (Scotland) and late 18th (England) centuries. Here, reintroduced beavers are a huge tourist draw, and beaver dams reduce the impacts of flooding—a big problem in the UK—although many farmers aren’t convinced. As Goldfarb writes, “Everyone shares a goal; no one agrees on strategy.”

One thing Eager was missing was a visit to Canada. The beaver is the country’s national animal and graces its nickel coin. Canada has acres of landscape shaped by beavers, and Goldfarb cites a number of Canadian studies, but a firsthand experience would surely have enriched his otherwise excellent story.

I’m highlighting the last paragraph in a horrible color because that’s just plain stupid. It’s that thing teachers do when they have nothing bad whatsoever to say about your work but they want to act like they’re doing their job so they give you stupid irrelevant advice along with your well-earned praise. Obviously there have been VOLUMES about beavers in Canada, most recently by Frances Backhouse and before that by Glynnis Hood. It is wonderful for Ben to cover the story from an un-canada-centric perspective for a change.

And this is a GREAT review, in a gut punch location. I heard from the publisher that he’s going to be reviewed in the Washington Post sunday, and I just found out he is going to be on local radio KPFA on Friday. 

With me too! So buckle up!

 


The struggle to keep water on a drying landscape always seems to wind up – well if not directly pro-beaver, then at least firmly beaver-adjacent. Take this recent article about Montana for instance. I’m not sure how much faith I’d personally place in a college whose initials are officially “UM” but I like where this is headed.

Drought is coming to Montana. How do we protect ourselves

Last year, Montana witnessed the driest summer on record. It was also the second hottest summer, which made the weather more unbearable. This extreme weather, driven by a warming climate, directly led to huge crop loss and the biggest wildfire season ever. According to the US Department of Agriculture, drought decreased wheat production in Montana and the Dakotas by 64 million bushels in 2017, and an estimated 1.3 million acres of forest burned across Montana.

“Water is the second air, the main resource we need,” said Nicholas L. Silverman, a hydrologist and water resources engineer who studies climate at the University of Montana. Riparian resiliency is the ability of waterside vegetation recovering from damages. These vegetation areas can be categorized into two types: low resiliency and high resiliency. Low-resilient vegetation are sensitive to environmental changes. When drought happens, they will die. On the contrary, high-resilient vegetation would bounce back and help protect against drought.

Wait, I’m trying to guess which kind beaver build. Hi or Low?

Beaver dams help build riparian resiliency by creating ponds and wetlands that hold almost 10 times the water without beavers.

To deal with this vicious cycle, Silverman said, we need to build high-resilient riparian areas. Silverman suggests three strategies to help riparian areas recover and become more resilient to the warming climate. The first is to reintroduce more beavers. According to Glynnis Hood, an environmental scientist at the University of Alberta-Augustana who specializes in wetland ecology and the impact of beavers, beaver dams can help store more water. She looked at 54 years of data in Elk Island National Park, and found that beaver dams secure up to nine times that of a pond or water source without beavers.

The second strategy is to build artificial ponds that mimic natural systems. Humans have significantly impacted aquatic ecosystems, and human enhancements can improve their resiliency one will help us to preserve water flows.

First, he concludes we need ACTUAL BEAVERS to do their thing and then we need to pretend to be beavers and do more of their thing. Hurray! They go on to say then everyone needs to change how they graze their cattle so that some plants are left and ACTUAL BEAVER can come you know, do their thing.. The answers to Montana’s drought has a flat tail, that’s for sure.

Ultimately, reducing greenhouse gas emissions will help to reduce the worst impacts of drought in Montana, but in the meantime, helping streams and rivers cope with rising temperatures will fend off some of the worst impacts of a warming planet.

Speaking of which I came across the COOLEST resource on the entire internet yesterday, I know you’ll want to play with it. Right click on a particular river or stream to find its watershed anywhere in the country. This is the one our beavers  live in, but you might want to check your aunts home in Georgia or Wyoming too.


There’s plenty of good news on this particular Sunday. First off this letter which Jim and Judy Atkinson cc’d me on. It’s being sent to the mayor and entire council.

Isn’t that lovely? Thanks so much Judy for following up with these very kind words! And hey speaking of the beaver festival. Jon took this photo yesterday of the remaining images of Amy Gallaher’s hard work and I thought it was delightfully ghostly I shared it with her.  Turns out she had just finished reading Ben’s book and had loved every last word. She was glowing with beavers and even though I had made myself promise never to mention a future beaver festival until a full month had passed,, I decided to mention that if she was ever crazy enough to want to decorate a beaver festival again we would love to have her.

Guess what she said?

“I thought you’d never ask! Of course I’ll be there”

Which if course made us laugh, thinking of me trying to be polite with duct tape over my mouth to keep from saying anything, and her wondering why we didn’t ask sooner and worrying that we didn’t want her.

You see how silly it is not to say what you’re thinking?

More good news, this arrived yesterday,  My first ever income from the written word. Which of course I’m donating to Worth A Dam. Mind you I’ve been published in journals and the like, but they  just take your work, they never give you dollars!

Hmm that’s a bucket load of good news. Is there anything else? Oh yes, Ben was on WAMC in New York yesterday talking with Joe Donahue about beaver benefits. Why don’t you play us out Ben.
