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

Category: Beavers and Fire Prevention


One of the continually interesting perks about maintaining a beaver website is that fascinating people from around the world seem to filter like manna onto your doorstep. Not too long ago I was contacted by Emily Fairfax, a graduate student in geological sciences at University of Colorado at Boulder who happens have a special interest in beaver dams and the water they hold. She has been following this website and even sent her mother-in-law to check out our beaver festival last year. (!) When she made contact she said

The vast majority of my work has been on how beaver dams change arid/semi-arid landscapes from a hydrologic perspective.’

Her research website says:

My current research focuses on the ecohydrology of riparian areas, particularly those that have been impacted by beaver damming. I use a combination of remote sensing, modeling, and field to work understand how beaver damming changes these landscapes and on what timescales those changes operate.

She especially was looking for stories or anecdotes about how beaver ponds help in fire situations, so I introduced her to some folks and showed her what I had come up with over the years. Which lead me to pay special attention when a recent discussion came up with Lisa Robertson on the Wyoming Untrapped FB page, which brought me to this amazing photo and story by Jeff Hogan.

Jeff is an extraordinary wildlife cinematographer. If you’ve ever watched a wildlife film by National Geographic or the BBC, you have probably seen his work.

This is the kind of thing he captures every day.

jeffhoganfilmsI’ve been filming beavers for 20 years now illustrating the benefits of an active beaver colony and pond. Live beavers are very important to our wild forest lands and watersheds. Far more important than whatever benefit humans may enjoy from trapping these beavers. I believe that a wildlife management plan that allows trapping of beavers is highly irresponsible and reckless! This image illustrates the benefit of a beaver pond in fighting forest fires. Filmed in 2001. Beaver pond is located in Granite Creek.

Now Jeff just happened to be at the wednesday night reading in Teton Wyoming of Eager with Ben Goldfarb and Wyoming Untrapped’s director Lisa Robertson. So Jeff made sure Ben had this photo and I made sure Emily had it too. You can see that the helicopter is scooping water to fight the fire out of the only place it’s available: a lovely beaver pond.  You can even see the lodge in the middle.

Beavers make a difference in firefighting, as they do in so many other ways.  I’m excited to see Emily’s finished work so we can document just how much. In case all this feels too much like school, take a moment to enjoy some of Emily’s delightful offerings on her website.

You don’t want to miss this. Follow the link to her amazing 360 view of a beaver pond. Go look, I’m serious. It’s so frickin’ cool.

 “Visit” a Beaver Pond!

Think beaver dams are cool? Visit one of my favorite ponds via a 360 degree photo I took. It’s the main beaver pond up at Schwabacher’s Landing in Grand Teton National Park!

Beaver Pond at Schwabacher’s Landing


Today’s post is brought to you by Dr. Joe Wheaton’s twitter feed. Please share it with every Californian you know. At least all those that live in flammable areas. (Meaning all of them in oxygen-based areas.)

 

This is Baugh Creek (a tributary to the Little Wood in Idaho) and this is part of the Sharps Fire.

The Sharps fire in Idaho was started by an accidental spark from target practice and has now burned more than 65,000 acres and was finally contained by crews at the end of August. I’m hoping there’s more water upstream that we can see in this photo where some beavers can go shopping because otherwise those are going to be some mighty hungry dam-builders.


As California continues to set itself on fire like a Hindi widow faithful, it might be useful to think specifically of one thing in particular that beavers do. They happen to do it better than anyone else in the world. And its all they do, every day, everywhere, 24/7 with minimal tools, for free.

Can you guess where I’m going with this? All the way to Alberta and this great article by Brenda Schoepp.

What do you want your fresh water used for?

It all began with industrious engineers who understood hydrology and the importance of water. They built dams and created wetlands throughout Canada, and in doing so had a system in place for water preservation and purification.

The harvest of the beaver had an impact on wetlands and our current-day contribution to climatic change. Wetlands are multifunctional systems that purify water and encourage a system of regeneration. It is estimated that 70 per cent of wetlands in Canada (65 per cent in Alberta) have been lost as part of this disruption in the natural order of things.

How do we protect the quality of the water when we don’t know what beavers know? How do we use less water when the economy is exploding? Do we fully appreciate and understand the profound relationship between action and consequence? And is there a political will to invest in science and technology to ensure water for all?

Good questions every one. And there probably isn’t a single answer, but one of them surely is furry. This is as good a time as any to revisit this wonderful chestnut by Ralph Maughan for Wildlife News.

Beaver restoration would reduce wildfires

After almost every large wildfire or fires that do significant damage to structures, people ask for proactive measures. The desire for this is rational. It needs no explanation.

The most common plausible sounding solution used in the Western United States is large scale fuel reduction — little fuel; little fire. A big problem with fuels reduction is that you have to pay to have it done. Potential fuel covers hundreds of millions of acres. We say “potential” fuel because what will burn varies greatly. Some years are too wet. Every year hundreds of fires burn out, but a wind, not drought could make them quickly into great conflagrations. Politicians often use the words “logging” and “fuel reduction” in the same breath, but commercial logging, where the land owner gets paid, only works for good timber. That’s mostly not what is burning. Dry brush, droughty green trees, dying or dead trees, cheatgrass, and annual weeds — that’s what is usually burning. It is difficult and far too expensive to eliminate these.

One idea that is rarely mentioned is to keep the stream bottoms green and raise the humidity. How could this be done? Let’s restore beaver to the creeks of the Western United States. This is much less expensive than cutting out or clearing potential fuels. It also has significant fish and wildlife benefits. We can often add flood control too, plus the recharge of aquifers.

A string of beaver ponds up a drainage is like a permanent fire break. The ponds not only enlarge the area covered with water, more importantly, they increase the portion of the creek or streamside area (the riparian zone) that stays green all summer. They raise the ground water level. Beaver ponds also increase the humidity of air in the drainage. The result is fewer hours in a day when wildfires can burn hot and hard.

Beaver could be a powerful tool to tame the effects of climate change.

Can we talk about those spongy marshlands that beavers make now? Can California look up from the raging torrents in Redding and Clearlake and think, gosh maybe I should be using a different method to clean my culverts besides killing the water-savers.

Anyone who puts two and two together will come up with this.


Well yesterday was fun, with little messages of encouragement for our 10th year  from folks around the globe. Now it’s time to get back to work. You know what they say, before anniversaries “Chop  wood, carry water“, and after anniversaries”Chop wood carry water“. Or something like that.

Here are two articles that deserve our attention. I’ll start with the grating one first. Why is it every article written about Peter Busher annoys me more than it interests me? Over the years I have come to think he basically knows his beavers, but he honestly doesn’t seem to like them very much.

The Secret Sex Lives of Beavers

The population boom can raise alarms in communities. Beavers are often viewed as a nuisance, causing millions of dollars in damage each year by chewing fences, trees, and decks. They build dams, which leads to flooding of homes, crops, and railroads.

But some behaviors can be beneficial, says Peter Busher, a College of General Studies professor of natural sciences and mathematics and chair of the division. Beaver dam building expands wetlands, whose functions include filtering toxins from water, supporting biodiversity, and mitigating floods.

Peter Busher poses with beaver captured for analysis

Busher has been studying beavers for four decades and was the first person to track the animals by tagging them with radio transmitters. He does his research in the Quabbin Reservation in Central Massachusetts, where 150 to 300 beavers con­stitute the nation’s longest-studied population, says Busher. Hoping to learn how humans can better coexist with beaver populations, he examines mating habits, birthrates, group structure, and how the animals migrate from one area to another. His findings could inform deci­sions about how communities respond to beaver activity and manage the animal’s population, both in Massachusetts and across the country.

Although beavers are among only 3 percent of mammals that are socially monogamous, raising their young exclusively with one partner, researchers do not know much about their pairing behavior. Do the parents also mate with other beavers and raise a mixed brood, or are they sexually exclusive? Busher wants to find out. He suspects that genetically monogamous beaver populations—those that tend to mate with one partner—increase more slowly and may stay in an area longer. If one of these populations were removed because of nuisance activity, he says, the area would likely be free of beavers for a while. But if the population were more promiscuous, new beavers could move into the area at any time; communities would then need to develop a long-term animal removal plan.

Promiscuous beavers? Honestly? Is that honestly what you think? Who thinks like that? Have you looked at every OTHER variable in their habitat that might differ between various beavers to rule out that food availability, or population, or stream gradient and prove that these it doesn’t influence which beaver are promiscuous and which aren’t? I’m sure, as a scientist, you would do ALL THAT before LEAPING to the assumption that DNA is responsible. I mean this is almost like race research.

How much trouble would you be in if you were posing that certain ethnicitys were more promiscuous?

The best research I have read on the topic described beavers as “opportunistic monogomists” – meaning if the right conditions happened to arise they would take advantage of them and mate outside the pair bond, and if they never arose it would be mostly okay with it and get on with the business of taking care of the family. I remember being amused when Rickipedia commented that this was pretty much the same for most male humans.

But Dr. Busher is trying to prove that it’s a beavers genes that make him roam. So that those prolific beavers we can kill more, and the faithful homebodies we can work with.

Are you sure you teach in Massachusetts? Because this theory is starting to sound positively republican to me!


The article that really interested me today comes from the irreplaceable George Monbiot and discusses the use of better language about ecology to capture public interest. Rusty of Napa sent it my way and I’m glad he did.

Forget ‘the environment’: we need new words to convey life’s wonders

If Moses had promised the Israelites a land flowing with mammary secretions and insect vomit, would they have followed him into Canaan? Though this means milk and honey, I doubt it would have inspired them.

So why do we use such language to describe the natural wonders of the world? There are examples everywhere, but I will illustrate the problem with a few from the UK. On land, places in which nature is protected are called “sites of special scientific interest”. At sea, they are labelled “no-take zones” or “reference areas”. Had you set out to estrange people from the living world, you could scarcely have done better.

The catastrophic failure by ecologists to listen to what cognitive linguists and social psychologists have been telling them has led to the worst framing of all: “natural capital”. This term informs us that nature is subordinate to the human economy, and loses its value when it cannot be measured by money. It leads almost inexorably to the claim made by the government agency Natural England: “The critical role of a properly functioning natural environment is delivering economic prosperity.”

I’m fully on board with the need to use language that enlivens and engages us rather than regulates our attention. But sometimes we are talking to politicians or biologists and need to convince them, and we think that kind of language carries more sway? Maybe it doesn’t. Maybe the only thing that matters to decision makers is what we celebrated yesterday: public pressure and votes. So engaging the public is more important than sounding objective.

This is my FAVORITE part.

On Sunday evening, I went to see the beavers that have begun to repopulate the river Otter in Devon. I joined the people quietly processing up the bank to their lodge. The friend I walked with commented: “It’s like a pilgrimage, isn’t it?” When we arrived at the beaver lodge, we found a crowd standing in total silence under the trees. When first a kingfisher appeared, then a beaver, you could read the enchantment and delight in every face.

Our awe of nature, and the silence we must observe when we watch wild animals, hints, I believe, at the origins of religion.

Something about that sentence feels very, very true for this woman who spent so many years in the company of beavers. (Not that we were silent the whole time.) Our beavers had train whistles and garbage trucks to get used to, and could handle a little talking. But there was definitely awed silence at times. Like when kits emerged or when an uncommon behavior was scene.

And it sure felt like the very best parts of church to me.

if we called protected areas “places of natural wonder”, we would not only speak to people’s love of nature, but also establish an aspiration that conveys what they ought to be. Let’s stop using the word environment, and use terms such as “living planet” and “natural world” instead, as they allow us to form a picture of what we are describing. Let’s abandon the term climate change and start saying “climate breakdown”. Instead of extinction, let’s adopt the word promoted by the lawyer Polly Higgins: ecocide.

We are blessed with a wealth of nature and a wealth of language. Let us bring them together and use one to defend the other.

Thank you, George for another beautiful column. I’m envious of the people who got to walk alongside you on the way to see those special Devon beavers. We very rarely feel reverence for what we consume or eliminate as inconvenient. But I have seen it time again on children’s faces watching our beavers.

Maybe its reverence, more than science, that protects nature.


The salmon suit was ALL over the news yesterday. I was thrilled to see it even made the radio in Oregon. Yesterday CBD actually had a matching donor so all the money that came in from the news was doubled!  I didn’t even realize it the announcement was cleverly timed to match the beaver moon which was apparently strongest in the wee morning hours last night. Everything about this must have gotten wildlife services attention. Lets see where this goes!

More treats to follow, because this wonderful letter by Connie Poten of Missoula Montana just ran yesterday in the Independent Record. Connie is the secretary of Footloose Montana, and writes a powerful letter. It has a few things that need tweaking but my goodness it even has a NEW FACT THAT I LOVE. And that so rarely happens anymore.

Let beavers work to prevent fires

Gifford Pinchot, the first chief of the Forest Service, called beavers this term is blocked. [Editors note: the name she writes he called them is very cool but not as yet unconfirmed by the forest service or Pinchot scholars so for now consider it cloaked.] Tens of millions of beavers created vast wetlands in North America, nourishing Native Americans, fish, wildlife, forests and meadows with life-giving water. Then came the European fur trappers, and in less than 50 years, Montana had no more beavers at all. Eastern Montana dried up as a result. Finally, beavers were reintroduced to recharge aquifers gone dry and save water from draining away.

Starting July 7 with the Crow Rock fire near Miles City, Montana turned into an inferno. The Lodgepole Complex fire burned 400 square miles. Montana became the epicenter of drought — the hottest and driest summer on record  —and got smothered in smoke. By Sept. 11, more than 1 million acres had burned. Animals burned alive and died from smoke inhalation; a coyote was seen with a leg burned off. Seeley Lake was plunged into toxic darkness for six weeks. Montana’s tourism industry shut down in much of the state. Hundreds were evacuated and homes burned. Two firefighters died.

We now face the cost of fighting these fires. Farmers lost $400 million in crops, ranchers were hit hard and the tate budget is spiraling downward. It doesn’t have to be this bad. We could make a small change that would help contain fires. We could eliminate recreational trapping of beavers.

Beavers create ecosystems. They build dams that hold ponds and restore streams, wetlands and floodplains. They turn hardpan into rich soil. They supply water for municipalities, irrigation and wildlife. Seasonal streams flow year-round and groundwater is stored, thanks to beavers. Beaver wetlands act as firewalls, mitigating forest fires. Firefighters use water from the ponds. When beavers gnaw down cottonwood trees, they spur more growth — cottonwoods thrive on disturbance.

As warming temperatures threaten cold-water fish like trout and coho salmon, the cold water at the bottom of beaver ponds makes a perfect habitat for juvenile fish. Beaver ponds nurture grasses, trees and shrubs, creating nesting sites and food for songbirds, forage for game animals and most species. Beaver ponds improve water quality too, by reducing sediments and pollutants.

In a time of accelerating climate change, drought and fire, we need beavers more than ever. They work for free and restore our precious water. What are we waiting for? End recreational beaver trapping now. Let our beavers go to work.

Isn’t that an AWESOME letter? Connie deserves all our praise. She even talked about Skip Lisle and beaver deceivers! No wonder Footloose Montana is so successful since even its secretary can deliver a powerful lesson with a pen. I love the quote about beavers being “water factories”. You know I’ll be tucking that away to share sometime in the future!

Una familia de castores ‘monta’ su casa en la cuenca del Ebr

Another delight was sent by Duncan Haley of Norway yesterday but the beaver world was TOO busy to share. This is an article about beavers in Spain that were supposedly introduced without permission. (Duncan swears the accusation is legit and because he has inside information so I trust him.) The article is in Spanish but use google translate if you want to read some really amusing beaver misunderstandings! The farmer has been watching the beaver activity using a night cam. I was especially interested in the interaction between the beaver and this Genet so I clipped that short interchange. It is easily the likely the most delightful beaver moment I will ever post here. I especially love the moment when the Genet waits to see if the beaver is following. Enjoy.

Don’t you think they play that every night? If you, like me, find yourself suddenly wondering what a Genet is, Duncan explained “Like a cross between a marten and a cat with spots like a leopard and a long ring tail
Wow. Doesn’t that sound amazing? Here’s one in the color.
