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

Month: November 2017


I received an update yesterday from the hardy Judy Taylor-Atkinson of Port Moody Vancouver who is working to save the beavers at the development where she lives. She is doing a wonderful job focusing public attention on the beavers and getting the community interested in them.  In fact she’s doing SUCH a fine job that I’m pretty sure at this point our beavers are jealous.

Yesterday she wrote this:

We had our first mini crisis last week when the beavers knocked down a large unwrapped black cottonwood tree and it landed on a homeowners fence, just damaging it slightly.   I was immediately notified by people in our neighbourhood who love the beavers and I went to work posting messages on our community facebook page and notifying the city arborist, Steve,  (who actually likes the beavers) and requesting the trees in that area be wrapped.  Steve sent his two staff, Alex and Doug, who have been trained by Adrian Nelson on the proper way to wrap trees, the next day.  

My facebook post read –

“Jim just came back and Silverlining landscape have removed the top of the aspen tree and Jim advised them to leave the branches and cuttings close to the stream bank for the beavers.  We will meet with the city arborist today and wrap that stand of trees.  The beavers have been eating mostly willow, dogwood, poplar and shrubs.  Some trees will be wrapped and others will be left as food sources because there is a natural balance between beavers and trees. Beavers open up the tree canopy to let light in and smaller trees will grow.  Some species of trees, like willow, have evolved with beavers and they actually grow faster if a beaver chops them down.  The greenbelt is changing from a “stream” ecosystem to a “pond” ecosystem.” 

That post seemed to settle everyone down (Jim is my husband).  The next day, I posted a picture of Doug and Alex wrapping the trees with the post –

“Thank you to Doug and Alex for wrapping the cottonwoods this morning and to Steve (our city arborist) for his valuable knowledge about our trees along Pigeon Creek. Steve said they are busy right now removing downed trees throughout the city (due to a bad combination of drought followed by intense rain and now a cold snap).”

Thankfully, Steve, the city arborist seems to be quite supportive (and interested) in the beavers.  When the beavers first turned up a year ago Steve didn’t know anything about them and now you should hear him!   He knows what kind of trees they prefer (and why), which trees offer the most nutrition for beavers (cottonwoods, poplars) and he’s not concerned about the willows at all.   He just has to make sure the trees don’t fall on a building and now he has a plan to wrap  those trees.  He has also been along the stream and is quite sure that the trees the beavers could potentially knock down will not fall away from the stream. 

Isn’t that wonderful? She is committed to making beaver friends wherever she goes, and NOW those lucky beavers even have an arborist who  is learning to love them!  (Does Martinez even have an arborist? Or know the word?) I asked for her permission to share this because I think it is inspiring to others who are thinking of doing something similar. She and her husband are hard at work in the community encouraging, explaining and de-mystifying beaver behavior. I wish very much I could resist this little rhyme that has crept into my mind,  because she deserves so much better, but there’s no avoiding it now.

Thank heavens for Judy

In Port Moody


There’s excellent beaver management news this morning from Idaho where the watershed guardians just installed a pond leveler for veterans day. Given the hard time that many beavers face in the Gem state, these critters are lucky indeed! Great work Mike Settell and team Pocatello!

“Thank you, Bruce, for serving on the Watershed Guardians board, providing inspiration, leadership and flatout hard work. We will honor your volunteerism by carrying on our work to help the Portneuf River Watershed, one beaver at a time!”


There are very few advantages to the thankless job of writing about beavers every day – (I mean there isn’t free beaver merchandise given at conferences, or drinks on the road with the team, or eager secretaries wanting to make a good impression) -there aren’t what you’d call “Perks”.

But there is  this: which apparently even the multi-million Canadian Broadcasting Corportation cannot boast:

A sense of HISTORY and the ability to see when things happen over again and again.

Rural Sask. municipalities look to solve big beaver problem

Beavers are burdening rural areas of the province, and now the Saskatchewan Association of Rural Municipalities is looking for solutions — including the restoration of funding for a program cut in the last provincial budget.

Beaver numbers have boomed to a point of overpopulation and the critters have been destroying infrastructure, according to several municipalities. At the association’s midterm convention in Regina on Tuesday and Wednesday, two of the matters on the agenda touched on the nuisance beavers are creating in rural areas.

“Problem beavers” and the structures they build can lead to road and property flooding, according to the SARM website. In response, the association created a beaver steering committee, representing a coalition of rural municipalities, associations and government.

Now doesn’t the article make it seem like this is a brand new solution that will tackle the problem in a brand new way and rid the poor folks once and for all of these pesky beavers? Except for I wrote about SARM and its coalition of 16th century tools to tackle the ‘exploding beaver population’ back in 2011. In fact, that column had some of my earliest graphics that still make me smile fondly today.

“Exploding beavers? Now that does sound dangerous! No wonder you found 500,000 to fight it! I guess America has seen shoe bombs and underwear bombs in the last few years, so why NOT an exploding beaver! It’s insidious!

Ohh. I just received a wire from the Ministry of Dangling Participles clarifying that the population of beavers has exploded, not the beavers themselves.  Whew. That’s a relief! I was going for my beaver-proof vest. I’m curious though, how do you know the population has exploded? I mean when is the last time you did a regional count and how do you know the numbers have increased?”

Funny thing about Beaver trapping. When governments rush in to take out massive groups of beavers,  populations have a way of recovering. In fact they often rebound, with more food available for fewer beavers and female caloric intake increasing so that brood size increases. You end up doing the same thing all over again in 1-2 years.

Hopefully you set aside another 500,000 dollars to take care of that problem?

Ahhh, I was so young and naive in those days. I actually thought Saskatchewan could be shamed into fixing their beaver problems with reasonable and proven techniques. Silly, silly girl. What did I know? I didn’t realize that they were the MOST BACKWARD and BRAZEN region on the entire planet when it comes to beaver management. They had the infamous kill contest two years ago that resulted in terrible press for the entire region. Literally hundreds of beavers were killed. And it didn’t help.

CBC might act like this is a “NEW” problem. But we here at beaver central know better.

In response, the association created a beaver steering committee, representing a coalition of rural municipalities, associations and government. At its conference, the association tabled a resolution calling for the restoration of funding for the Beaver Management in Provincial Parks program, which was cut from this year’s budget.

It also called for a special permit to control nuisance wildlife within a specific distance of threatened fields or infrastructure. SARM hopes the government will restore funding for the beaver management program in the 2018-2019 budget. It also called for a special permit to control nuisance wildlife within a specific distance of threatened fields or infrastructure.

Good luck convincing folks to spend money and not solve the problem again. I’m sure you’ll get it.  I mean someday they’ll probably realize that the amount they have been spending over and over again has been useless. Some bored intern will crack open the budget book for the last 20 years and realize how much money they’ve handed you  to throw away  over the years and  someone with a brain will demand actual accountability for the contract.

But don’t worry,  I’m sure that day won’t come anytime soon.


 

Speaking of young naive things that have zero idea what’s ahead of them, It seems like a good time to mention that today is our 32nd anniversary of wedded bliss. Who would allow these children to be married? What on earth were those foolish babies thinking?

Happy Anniversary Jon!

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.


beaversaryTen years ago today there was no Worth A Dam, no website, and no beaver community. There were only a bunch of citizens who thought it was a bad idea for their city to kill their beavers and showed up at a meeting to tell them so. This short clip of the UK documentary Beavers Las Vegas, produced by the independent film company Middle Child Productions, shows only the barest HINT of how many passionate and persuasive comments occurred. The clip I put together isn’t very long, but you should definitely watch all the way to the end to understand why it was so successful in changing the city council’s plan.

That Dam Meeting! from Heidi Perryman on Vimeo.

A handful of very passionate folks gathered at my home right before the meeting to discuss strategy. Former city council member Bill Wainwright brought port from the local city vineyard to share for courage, and gave us lots of advice about how to pitch our message persuasively. I spent the week handing out these stamped opinion cards and I’m sure hope the city got several.

That night, having never spoken at a public meeting before, and after barely being brave enough to call Sherri Tippie and ask for advice about relocation, I delivered the following comments:

I’m a lifelong resident of Martinez and a downtown homeowner.  While I would much rather have the beavers relocated than killed, I feel the city has failed to capitalize on a remarkable opportunity and let us all down.  In this case the DFG made some unique concessions and creative solutions, the Lindsay museum agreed to go above and beyond its calling, but the city of Martinez did neither. 

Although it has been widely reported that the city “Tried to think of another way to manage flood risk” the evidence for this is not strong.  The city Manager’s report does not even mention water-flow or leveling devices.  In fact these techniques have been used successfully for years and are well researched and understood.  Reports show a 93-100% satisfaction with them.  There is other evidence of neglect: the hydrology report does not mention tides and describes the dam as a “concrete weir” which of course it is not.  Finally, no report has looked at the likely environmental impact of removing the dam and the possible effect on new and returning species that depend on its waters: such as the famous baby otter, or the less famous but still endangered California pond turtle which has been in evidence.

If the city is determined to remove the beavers, they should be aware that successful relocation is not uncomplicated or well understood.  Since the state of California does not routinely allow relocation, there are few trappers trained in its use.  Hancock traps must be employed, and when misused can still result in harm or death.  Snare traps can cause invisible internal injuries.  Beavers have no internal temperature regulation and are there for highly vulnerable to hypothermia.  Families must be caught and released together.  I have spoken extensively with the nationally renowned expert in this area, Sherri Tippie, and have outlined her suggestions as well.  I submit them along with reports on flow control for their review.

 Many cities face these crises with technology, creativity and compassion. I wish Martinez was among them.

In the end it didn’t matter what I said. What mattered is what 50 people got up and said, and what 200 people applauded and cheered. The council sat frozen like four [Janet was in China, thank goodness] deer in headlights and we could tell we had all their attention. We knew the meeting was special while it was happening, getting more remarkable with every comment and cheer of solidarity. No one left early. And no one got tired. Nearly four hours sped by. To me it felt like a huge electrical charging station that filled me with unexpected energy for the road ahead. Remember, there was an offer on the table to ‘relocate’ the beavers, and I truly thought I might be the ONLY person to show up and disagree with that.

People sometimes assume that I somehow organized or ‘made’ that meeting. But they couldn’t be more wrong.

That meeting made me.

This has been a busy month. I knew another pin was going to drop, but Ohio? Who would have guessed?

John Switzer: Beaver moon highlights species’ revival in Ohio

CaptureThis month’s moon is called the beaver moon, and it was full Saturday.

It is called the beaver moon because now is when beaver dens are snug and stocked with food in preparation for the winter. All fall, beavers have been cutting branches and taking them to their dens so that they can dine on the bark and wood. Sounds like a tasty winter meal.

There’s another reason the November moon is called the beaver moon. Hal Borland wrote in the book “Twelve Moons of the Year” that by November the beaver’s pelts are in prime condition. Back during this nation’s settlement, beaver hats were all the rage here and in Europe, and pelts were considered the same as currency. Their pelts were so desired that by the 1830s, beavers had been extirpated from Ohio, said Jim McCormac, a wildlife biologist.

But beavers are again relevant because they have returned to all 88 Ohio counties, entering the state from the north and east, McCormac said. McCormac said Ohio is home to an estimated 30,000 beavers. He also said that if beavers live in your area, its biodiversity and natural heath are profiting “big-time.”

Many plants and animals benefit from beaver dams and the ponds they create. He gave the example of the beautiful wood duck, whose population is increasing partly because of beaver dams.

“There are no better ecological engineers,” McCormac said of beavers.

Capture

But having beavers in the area is not without its negative consequences. When they dam up creeks and streams, they sometime cause the flooding of farmland and other places that humans rely on.

I’ll give you an example. Early last spring I went out to Glacier Ridge Metro Park near Dublin and the park’s wetlands and a few of the nearby bike trails and hiking paths were covered by water. Beavers had dammed up the small stream that flows through the area and, by the end of the winter, caused a small flood.

But all was not lost. The Columbus and Franklin County Metro Parks placed pipes through the dam so the water level could be easily lowered mechanically. “That allows us to drop the water down and not interfere with the beavers’ activities,” said Peg Hanley, spokeswoman for the parks system.

WOW! Jim McCormac is a wildlife biologist who knows his beavers! My goodness that’s exciting to read from the state. You can tell the columnist, John Switzer of the Columbus Dispatch, is not exactly sold on the flat tailed animals yet – but this article is a formidable start. I’m terribly pleased!

I was so impressed that I had to go searching for Jim McCormac and found his nature blog, Ohio birds and Capturebiodiversity. It is a wonderful collection of photographs and information. Jim is photographer and a self-described naturalist. The website has been around since 2007!

“I am a lifelong Ohioan who has made a study of natural history since the age of eight or so – longer than I can remember! A fascination with birds has grown into an amazement with all of nature, and an insatiable curiosity to learn more. One of my major ambitions is to get more people interested in nature. The more of us who care, the more likely that our natural world will survive.”

Obviously his site has enough respect and readers to get attention, and his opinions about beavers are making a difference. Thanks Jim! You are welcome any year at our beaver festival!
