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

Month: March 2020


Yesterday saw the successful completion of the very first beaver conference on the Eastern seaboard. Congratulations to Mike Callahan and Scott McGill for having the courage and fortitude to make it happen. And congratulations to all the incredible speakers and participants. By all accounts this was an event that deserves repeating, and it made a big difference to a big section of the country.

Our correspondent Doug Noble will have an summary to share soon but sent a slide show in the meantime we can just say HURRAY for a job well done!  I know right about this time at the Oregon conference I’m starting to feel a little sick of beavers, so I hope they all have some great hikes or netflix to unwind with. The English folks are visiting the Smithsonian today, so that will be an excellent way to de-beaver.

On the western front we were very excited also to receive our souvenir ‘towels’ for the festival. They came out so lovely and are a very sturdy vintage look fabric., Amazingly, the company that made them is in Nashville, Tennessee ‘Canvastry’ – the very city that was hit by the horrible Tornado the morning the towels arrived! The man I worked with assured me that everyone in the company and their business was safe but many had lost power due to the event. He said it was a small price to pay when 24 of their neighbors were killed!


You can pick yours up at the festival. No kitchen is complete without one. Or two.

Now for the column out of Mississippi today that deserves a little bit of our attention. I would complain that it takes such a long time to consider anything positive about beaver but given where its from I think we have to cut Brad a lot of slack. I don’t think I’ve ever ready any good news about beavers from Mississippi. This is a first,

BRAD DYE: Seeking to understand beavers

The road covers roughly one mile from the gate to the field. Familiar, yet ever-changing, the stretch of land that I have walked hundreds of times contains a beaver pond that is a small ecosystem in itself. To me, the tract is more than part of a tree farm or hunting land. It is a living place where decisions can have lasting impact.

My immediate thought was that these pests needed to be removed. After all, their recent industrious engineering efforts had led to the water that was now flowing over the road, thus eroding it in several spots.

The mission was clear–get the water off the road before more damage occurred. However, standing atop one of the dams I found myself wondering what positive impact these bucktoothed ecosystem engineers were having on the land? What role did they play?

Lets get this in contect: 150 people were meeting at that very moment and had flown for thousands of miles specifically to talk about the many, many, many, answers to that very question. Couldn’t Brad know something about that? We all start somewhere. He was inspired by watching “The Biggest Little Farm”

In the documentary the Chesters discovered that the coyotes were actually keeping the gopher and rabbit population in check which benefitted their orchards and crops. What benefit, other than the wood ducks, were the beavers having?

Back home, I began my beaver research in an effort to “seek to understand.” According to Dr. Jessica Tegt of the Mississippi State University Extension Service, “Beaver ponds supply feeding and breeding areas for many species of waterfowl, reptiles, bats, birds, and insects. They provide essential edges and forest openings, create productive bottomland forest and supply moist-soil habitats for vegetation and wildlife.”

Isn’t this exciting? He’s on the actual CUSP of starting to understand something profound about beavers. We’ve all been there. I remember my own cusp lo these many years ago. Can I just say, too bad he’s in the Magnolia  State? Not to be dismissive but that is one hard place to find answers.

Clearly, beavers provide benefits, but they also cause damage. Jim Miller of the MSU Extension Service recommends trapping as the most effective method of reducing beaver damage. However, again it seems balance is key.

According to Miller, “Diligence and persistence is necessary for landowners to keep beaver damage at a tolerable level.” To me, that says strike a balance, find a way to live with them and limit the damage they cause.

So, what to do? I found several options to keep the beavers from clogging the culvert. I will start there. Will we trap again?

Brad needs us. Brad needs answers, If he keeps watching the pond he’ll find out ‘why’ to save beavers. But he’ll needs some help with the ‘how’. You can email Brad and tell him all about what we learned about how and why to live with beavers at: braddye@comcast.net.

Perhaps, however, we will do it with a goal of maintaining balance and limiting damage, not elimination . I’ll keep you updated on how these coexistence efforts work out. I look forward to seeing you out there in our great outdoors.


“Before I will see the worst of you all
To come into danger of death or a thrall,
This hand and this life I will venture so free”:
Was not this a brave bonny lass, Mary Ambree?

Well, sure I didn’t exactly storm the castle but I did okay and told the story well enough to earn some praise.It’s odd presenting remotely because I couldn’t hear the audience, although I am told there was one. Usually I hear laughter or ‘ahs’ in the right places and know how things are going, but with this I heard nothing until the questions at the end!

The fun part was being on the phone with Michael Pollock who, in addition to being friendly and brilliant, is also at GROUND ZERO for Covid-19 and dealing with a pretty unbelievable work environment at the moment. I guess if you work for the federal government right now your job is to NOT get the disease and also, ironically, not appear to be concerned about it either.

His presentation started on the evolving history of rivers and how much beavers were a part of that and how plants/trees depended on their work for nutrient regeneration etc – and had basically ‘trained them‘ with evolution to do what they do. (What an interesting thought!) Then he transitioned to talk about the work they are currently doing in the Scott’s Valley with BDA’s.

He also talked about how he hears over and over and over and over about beaver dams blocking salmon (which he knows they don’t) and they constructed a study to address this directly using a pit tags to track the moments of salmon they released specifically in a controlled dam to monitor the movements. They repeated it for steelhead and the paper found everyone could negotiate the dam. It is still in review but is going to be published soon and everyone was happy about that.

Anyway, he also said, alarmingly, that the California salmon population is “Tanking” and that the numbers are down to a few thousands. This was really shocking to hear, and made me think about all the obstacles we are giving them and all the beavers we are taking away. It also means it’s as good a time as any to talk about this which was published recently in Earth Island.

How Much Longer Will Wild Coho Hang on in the Golden State?

“Usually between here and the road there’s a half dozen redds or more,” says Todd Steiner, pointing 100 feet or so downstream to where Sir Francis Drake Boulevard passes over the confluence of Lagunitas Creek and San Geronimo Creek, near the town of Lagunitas. But only two ribbons hang from the trees. That’s been the typical story for this year’s coho salmon run throughout the Lagunitas Creek Watershed. Even for a wild salmon population that’s been listed as endangered since 1996, this year’s spawning survey came up with significantly low numbers.

This current year is one of the lowest numbers we’ve seen,” says Steiner, who is the executive director of the conservation group Turtle Island Restoration Network.

Marin has been talking about this issue for a while and arguing among itself about whether to reintroduce beavers. Are we going to keep arguing until the entire salmon population is gone?

Historically, anywhere from 5,000 to 10,000 adult coho created more than 2,600 redds in this watershed each year. According to NOAA’s recovery plan for the federally endangered Central California Coast population of coho salmon, Lagunitas Creek and its tributaries now have the capacity to hold 1,300 redds. This takes into account that half of the salmon habitat in this river system has been blocked or submerged by reservoirs that hold the water supply for the quarter-million people who live in Marin.

On average, Steiner and his team count 250 redds annually, but that number has been steadily decreasing. This year, there were less than 50 redds.

Fewer salmon eggs mean fewer salmon period. Or no salmon. Has California even considered that? We are still planning on a salmon season this year. But our time is running out. Its long past time for drastic measures.

For the past few years, SPAWN has worked closely with the National Park Service to rewild these two communities on federal land. In what was once Tocaloma, where SPAWN has made its headquarters, Brown points out where creekside retaining walls and structures have been replaced by restored floodplain. With help from volunteers, SPAWN placed fallen logs in the creek and built overhanging banks with straw logs to encourage logjams and side channels with slower water. Native grasses and willows from an onsite plant nursery have taken root in the riparian area, their shoots poking through a biodegradable erosion control fabric.

“It’s like a beaver pond,” Brown says. “It’s backwater habitat that’s quiet, complex, and deep.”

Of course, emulating beavers on just a few sections of the watershed goes only so far and, as Steiner says, won’t be enough to restore endangered salmon to NOAA’s goal of 1,300 redds. “At the same time that we’re repairing the land-use mistakes of the past, we’re repeating them,” he says.

Hey you know what ELSE IS LIKE A BEAVER POND????? A frickin’ BEAVER POND!!!

What on earth are we doing allowing any beavers in California to be killed when we know full well what an important role they play for salmon and how dire the situation is? Our salmon population is beyond dwindled and its like we’re killing off the few heroes that can help it.

Imagine if we were preventing firemen from moving in to a community because they took up too much space and blocked development. Do we need them any less? Our bad decisions are going to make us go up in flames and the only ones who could have helped we made sure were gone.

Hmm, that’s depressing. Have a nice beaver video as comfort, Courtesy of the Norwegian Beaver Project.


By all accounts yesterday was a splendid beaver day, with presenters from around the world really swinging the bat hard for beavers. To the right is Frances Backhouse posing with conference organizers Scott McGill and Mike Callahan (in disguise). Here are some highlights from yesterday Sharon and Owen Brown of Beavers: Wetlands and Wildlifeand were presented with the lifetime achievement award, Skip did a very well received presentation on the history of the beaver deceiver (summarized by Malcolm Kenton) and here’s a brief run through of what I’ll be presenting today.

The only mess-up of the day is that Emily Fairfax didn’t get time to present her awesome fire dissertation – It was a packed schedule and either things started late after lunch or James Wallace couldn’t squeeze her in – but she was hoping to be able to say something about it last night and in her connections with people She was a good sport of course and Lord knows we’ll be hearing from her again soon!

Check out these great notes by Malcolm on Skip’s Presentation, Worth A Dam’s Emsissary Doug Noble said he stole the show.

Skip Lisle, inventor of the “Beaver Deceiver,” speaking at #BeaverCON2020:
– The Beaver Deceiver is a flow device, but not all flow devices are beaver deceivers!
– We’re like moose — we like wetlands and we know where to turn to make healthy, productive ecosystems. We need to develop a common language & history.
– We’re lucky to live at a time when there are tremendous opportunities to save society a great deal of money with creative long-term remedies and create tremendous habitats.
– There’s a lot of pushback out there because people are used to wetland areas being drained – the culture associates wetlands/swamps with stagnation, disease, “wasted land” and various unpleasantness. So many places inefficiently keep killing beavers in the same places over and over again.
– In my career at the Penobscot Nation, my friend and I kept trying and building junky flow devices until we came up with the successful trapezoidal concept. The trapezoid had to get larger because they’re attached to the dam. Dam-leak separation makes a flow device more robust. Though they’re smart, beavers don’t do much deductive reasoning and can’t grasp the hollowness of a pipe.
– There’s a lot of controversy about where flow devices can work, but I don’t have any problem with zero inches/feet of water. A dry flow device can do a great job protecting beaver habitat upstream. Getting people to stop killing beavers is another issue — there are wide-open trapping seasons in most of these places.
– Every site is different so I need to put in a lot of thought as to what device best suits the place. Some culvert protectors need floors and some don’t.
– We’ve done enormous damage to wetlands after draining them, but beavers can repair all that if we just stop killing them. One beaver in one month (before moving on) brought so many birds to a site I worked on that weren’t there before. It’s miraculous! Remarkable wildlife viewing spots can be created in very short order. Every town can do this.
– I build simple wood structures to guide beavers’ damming — I don’t use the term “beaver dam analog” because it doesn’t need to look like a beaver dam to get them started.
– You can have a long beaver dam parallel to a road and have the water level much higher than the road, with a few pipes through the dam and under the road, and the road stays dry.
– There’s also an aesthetic and spiritual value to keeping beavers on the land — they’re dynamic, fascinating and all different. They bring a lot of joy to our lives.

A packed house with Doug Noble sitting next to Sherry Guzzi of Tahoe!

Happy SuperBeaver Tuesday!

It’s the day when these states vote in the primary, with California declaring relevance for the first time EVER in a presidential contest and these folks step up to the microphone at the first ever East Coast beaver conference. That humm you hear in the air is the vibration of change trickling through the waterways across America and perfuming the open spaces with the sweet sweet smell of freedom and beavers for all.

And that’s just the line up before lunch! After lunch there’s Emily Fairfax and Glynnis Hood and the plenty more. Hopefully they’ll be some snippets to share with you tomorrow. I can at least share my part of tomorrow’s lineup, which I hope comes off with minimal technical difficulties. In the mean time just look at that lineup and think how much luckier every beaver on the Eastern Seabord just got because of today!

A week ago Friday I told you was the fish and game commission meeting in Sacramento where they considered the rule change for beaver depredation. Well not so much considered as ‘heard’. Since Tom Wheeler of E.P.I.C. who authored the rule change didn’t want to drive down from Oregon. the Center for Biological Diversity had Lalli Venkatakrishnan there to read a position statement. And it was good. Now we don’t know the outcome because they referred it back to Bonham’s desk and we can only hope he doesn’t leave it in a dusty pile in the corner of his desk or light it on fire, but at least, for one brief shining Camelot moment, we made them think about it.

Remember what Gandhi said:

First they Ignore you.
Then they laugh at you.
Then they fight with you.
Then you win.

Well we ain’t on step one, anymore.

I have been trying to hunt down photos of cascading beaver dams for Amy to use in her artwork, and I thought you’d want to see these.
