MORE GOOD BEAVER NEWS IN TENNESSEE?

Yet another surprise to come out of the Volunteer state, this one in the form of sand painting. They seem to be towards the end of a game of ‘telephone’ – remember that elementary game where you sat in a circle and whispered into the ear of the child next to you so that one by one the message made it’s way around the room? By the time it gets to the end of the line it’s a little tangled up.

But at least they get it. And that’s huge.

How Painted Trees Are Saving The Lives Of Beavers In America

Trees in Tennessee’s Chattanooga city are being painted with non-toxic paint in a bid to prevent unnecessary beaver deaths in the US.

The bottom of the trunks are being painted in bright colors. The move came about after the city’s Parks and Outdoors department consulted the Humane Society of the United States (HSUS). The latter provided advice for a non-lethal solution to the problem of beavers destroying riverfront trees to make dams. 

Despite being a natural activity for the species, beavers’ chewing can leave tree trunks significantly weakened. Specifically, in Chattanooga, trees have the potential to fall into a nearby children’s playground or across a pedestrian footpath.

Never mind about the BRIGHT colors, or the fact that this NEW technique has been around a decade before Martinez tried it more than a decade ago. Never mind that we found it lasts no more than 5 years and needs to be reapplied when the tree grows. They are taking steps towards coexistence, and that’s something.

Chattanooga’s Parks and Outdoors department claims to have tried a number of preventative tactics before turning to painted tree trunks. These included protective fences – which the beavers climbed – and dousing trunks in hot sauce, which washed off in the rain.

So far, the most successful approach has been the use of non-toxic latex paint mixed with water and sand. The sand acts as an irritant to the beavers’ sensitive teeth, causing them to go looking for wood elsewhere. It is noted that painted trees have displayed light bite marks but nothing more, leading to assumptions that the painting technique is working.

This year is the first that officials have noted repeated beaver activity. According to Brian Smith, the Chattanooga Parks and Outdoors communications and marketing director, it is unclear where the beavers are taking their wood hauls. However, when they source wood that does not pose a threat to human health, they are largely left alone. And, considered a vital part of the region’s biodiversity.

Of course they do supplement with a lot of aquatic plants and grasses especially as the season gets greener. Your trees will be more endangered in the dead of winter when there’s nothing else to choose.

HSUS states that beavers are not the only animals killed to “manage” human-wildlife conflicts in the US. It highlights that many species labeled as nuisances are also “culled,” instead of encouraged to carry out their natural activities away from human populations.

Raccoons, skunks, chipmunks, and even bears are specifically named by HSUS as species threatened by such extreme measures. The nonprofit subsequently calls for a change in tack, as killing animals “only addresses the symptom of the problem, not the cause.” As such, the issue is likely to recur.

The Wild Neighbors program sees HSUS working with local agencies across the US. These include animal shelters, law enforcement, wildlife agencies, and more. In total more than 630 are signed up to the initiative that produces and promotes educational resources about how humans and non-human animals can coexist, without choosing lethal action. 

HSUS reports that since 2020, it has trained more than 7,000 animal care and control experts to use non-lethal resolution techniques when dealing with wildlife.

The Humane Society came to the Martinez Beaver meeting long ago. Just remember that before there was Worth A Dam or the Beaver Brigade or the Beaver project or Beavers Northwest, there was HSUS. In fact it was John Hadidian at the HSUS that paid for Skip Lisle to come do a class on flow devices that inspired Mike Callahan in the first place back in the day.

There would beaver no beaver Institute at all if it weren’t for the Humane Society. Think about that.

Just so you know, though, bright colors don’t work “Better” and ask someone how to secure wire wrap because it lasts a lot longer when its done correctly.

GROOMING FOR SUCCESS: BEAVER VERSION

A beaver grooming is a regular site to see and as likely to be photographed as a beaver chewing or a beaver building a dam. Maybe more likely, since grooming happens on land and people are way more impressed at beavers on land and likely to snap a photo. Grooming isn’t about vanity, it’s urgent beaver business. Life or death self care. If it didn’t happen every day, especially in the colder places, the beaver couldn’t exist.

You’ll be happy to know that such an important job comes with the exact right tools for the job. The so-called grooming claw which is a split nail on their back foot that is perfect for fluffing up that fur. We were recently treated to an excellent grooming profile from the Winterberry Website,

Beavers Grooming and Specialized Split Claw

Beavers groom frequently, both in the lodge and on land, to remove debris from the coat and to waterproof it with oil from anal glands. When the animal emerges from the water to groom, it may start with its face and head, or with its belly. It begins by raking the fur with its fingernails, and then gets some difficult to reach spots with its hind feet. The two inner toes on each hind foot are modified for grooming. The innermost toe nail opens and closes over the toe, like a bird’s beak, and functions like a coarse toothed comb. The second toe has a “split nail” or “double nail”. The former term is more commonly used but the latter term is, perhaps, more accurate. It really is a double nail: It has a true nail and an additional horny growth between the true nail and the toe. The additional horny growth has a finely serrated upper edge which serves as a fine toothed comb.

Of course a beaver grooming is a camera ready moment, but two beavers grooming eachOTHER, well that just resets the whole scale for cuteness. She says beavers mostly do mutual groom in the lodge, but we know that’s not exactly true.

DEGREES OF BEAVER FREEDOM

I think I mentioned before that I was horrific at math and oddly skilled at statistics. I’m sure there’s some kind of left brain/right brain distinction to explain some of it but for what ever reason one made sense and the other made me panic. No matter who taught it, No matter how much I tried.

One of my favorite concepts used in statistics was always “Degrees of Freedom“, Usually calculated as N=1, it basically it refers to how many chances you might have to achieve those same exact results given the number of times you tried or how many people you tried with. As the degrees of freedom go up the odds of it happening again also go up so the rarity of the results go down. As the degrees of freedom go down, the odds of it happening just like this ever again go down and it becomes very ulikely. Until there is zero chance.

I mention this because in the back of my mind I tend to think of the days before the annual Worth A Dam ravioli feed as Degrees of Freedom. As in “There are this many chances to get it wrong or forget a detail or have to take someone to the ER and still achieve the desired result.” The closer we get to day, the room for error gets lower and lower. As of this morning there is one day left before our 5 course dinner for 13 people. That means one day to get the house set up and make sauces ready and dip the cookies in chocolate. If we were visited by unexpected relatives today, or broke someones toe or had a power outage – tomorrow would become nearly impossible.

In other words, we are down to 1 Degree of Freedom.

Today is a day for Chinese takeout from the cartons in the living room so we don’t mess up the silverware or the table setting. And it’s a great day to read this cozy column by Patti Smith from Vermont which we always enjoy.

Remember when last we heard from Patti she was mourning the death of her beloved beaver Willow, who after a very long life had been unable to escape a bear.

The View from Heifer Hill: Finding an old friend on the river of life

During the last week of December, I skied down to look for the beaver that recently moved into the brook below my house. Beavers do not relocate in December unless calamity strikes. I suspected that a raging torrent from rain and snowmelt had destroyed this beaver’s dam and washed its food cache downstream. While this new location offers good foraging, the rocky stream bottom provides little mud for sealing a dam. Without a deep pond, ice can seal the entrance to a beaver’s lodge, trapping the beaver inside.

I had tried hollering on several occasions to entice this beaver to appear. Since that technique hadn’t worked, I decided that on this visit I would use the stealth approach — sitting quietly and waiting for the beaver to reveal itself. Once I settled myself by the brook, I noticed that the beaver had been building a lodge directly across from my seat. After a few minutes, I heard the gurgle that announced the emergence of the occupant. The beaver that surfaced paddled quickly over and swam back and forth a few times before lunging up the icy bank and onto the snow beside me. I was so pleased to see the notch in the tail that identified this beaver as Dew.

I first met Dew eight or nine years ago. The uncertainty stems from not knowing if she is Dewberry, born in 2010, or Sundew, born the following year. Either way, I met her shortly after she was born to that champion of beaver survivors, Willow. “Survivor” might seem a strange thing to call a beaver who was just eaten by a bear, but she lived to near the maximum lifespan for a beaver (about 20 years). I have not yet determined her exact age, but the teeth I recovered will allow me to.

Isn’t it wonderful that after losing her friends and matriarch of so many years she would run into one of her children who just moved in after losing her old house in storm? Mother nature can be pretty dam sweet sometimes. When she’s not busy doing the other thing.

Dew is the only one of her offspring known to survive, aside from the yearling Gentian. I concluded last month’s column with the hope that Gentian would inherit her mother’s penchant for longevity. Given that I could not find any of her siblings, I didn’t hold out a great deal of hope. Yet here was Dew — approaching her ninth or tenth year! Dew, who seems to have survived her first mate, Ilex, and is now wintering alone in this unlikely location. Given her heritage, I give her much higher odds of surviving this challenging winter than other beavers. I have seen her mother survive as bad.

Patti is such a delightful mix of science, heresy and affection. She pretty much breaks all the rules about not naming or feeding the animals you’re studying. But she also seems to learn more about their lives than anyone who follows the rules ever will.  Ever time we get to visit Patti in Vermont my heart swells with the deepest fondness and I am reminded of my own days watching beavers.

Patti is a kindred spirit.

On New Year’s Eve, I took a few friends out to visit her. Along the way, a dark shape was spotted hustling away into the shadows. When I hailed the beast, it stopped, then turned and came toward us. There was Quirinus, one of the porcupines I have been studying. He paused on his travels to eat an apple with us.

The forest, glazed in a mix of ice and snow, shone bright in moonlight. Once we settled by the brook, Dew arrived and began opening up channels in the slushy ice. She took an apple and swam to her lodge to eat it before reappearing and clambering up on the opposite bank. There she spent 15 minutes in elaborate ablutions, scrubbing and combing every bit of her corpulent physique. One of my friends had a blazing headlamp that lit up the scene like stage lights. Dew seemed to be preening for her audience. Why not? Beavers are social animals, and she had been on her own for at least several weeks.

I am so glad that she gets to spend quality time with the beaver after losing his or her mother. I remain completely mystified about how she tells them apart. We only ever had a few beavers whose identities I could spot on sight. Mom with her chinked tail. Dad with his size. GQ with his good loos. Mom II with her red fur. That’s about it.

Maybe you do better? I have a touch of prosopagnosia. I can barely tell humans apart.

When Dew finally swam off, we headed upstream a bit and built a fire. There in the snowy forest, we enjoyed the rising sparks, and a very localized rain shower caused by the melting ice on branch overhead. I couldn’t imagine a more beautiful transition from one year to the next. I was warmed by the fire and by knowing that a new beaver ambassador would carry on the work of my old friend Willow. May the new year bring such joy to you.

And to you Patti!

 And may the new year bring joy to any and all reading this site. Wish us luck dipping the tails today. I would invite you all for dinner but consider yourself lucky to escape it. We are not at all generous hosts who do this out of the goodness of our hearts and a love to entertain. We actually do this to compensate for demanding terribly exhausting days of service at the beaver festival and the willingness to resist saying “NO” when being asked for the millionth time. You know what they say, To those whom much has been given, much will be asked.

It’s one free dinner that actually costs the attendees a lot. It dam well  better be delicious!

First a followup from yesterdays cool story about the foundation that funds flow devices. Mike Callahan says this:

Yes, his estate’s foundation has been critical in helping to fund flow device installations in western MA over the past 9 years or so. The Robert Theriot Foundation grants have been hugely successful in incentivizing towns and property owners to try nonlethal management. It has been the spark that got the ball rolling in an area that was traditionally trapping only. The grant is administered by the MA Society for the Prevention of Cruelty to Animals which they do at their own cost. See ://www.mspca.org/animal…/berkshire-beaver-grant-funding/
In fact, this flow device grant program has been so successful that it was one of the main reasons I started the Beaver Institute. My hope is that our nonprofit can raise grant monies to incentivize flow device installations across North America! Now to find a grant funding source….. :-

Wow!

Here’s the program website.  Click on the image for the link. And think for a moment about the wonderfully small world we live in.

Now onto today’s business. I see Ben Goldfarb’s national geographic article got picked up by NatGeo Australia. So that’s gotta to be $ in his pocket. Also his book got a dynamic review from the editor of the Baker City news in Oregon. Obviously the editor feels about this book the same way the exact same way you felt about your second boyfriend in college. He’s crazy about it and  loves it more than any book he ever read and he hates himself for loving it a great deal. Over and over.

We can all understand that, right?

COLUMN: Book highlights the many benefits of beavers

I recently read a book-length ode to the beaver, and as is typical with such works I was in some passages caught up in the author’s adoration and in others a bit fatigued by his fandom.

Mostly it was the former.

This isn’t just a book-length account, but an actual book. And a fine one. Indeed I don’t recall enjoying more any book about wildlife biology and natural history that I’ve come across in the past few years.

Besides their potential to keep smaller streams from going dry — obviously a benefit for fish and other aquatic species but also potentially a boon for downstream farmers and ranchers — beavers’ constructions can also contribute to higher water tables and to lower water temperatures.

It doesn’t seem to me an exaggeration to describe beavers’ capabilities as miraculous.

And yet, by the time I reached the halfway point of Goldfarb’s book I became just slightly annoyed. Not enough to stop reading, to be sure — the story was compelling, and Goldfarb’s prose a pleasure, from start to finish.

But his constant extolling of the beaver’s virtues began to strike me as a bit of overselling. The thesis was just too pat — that the slaughter of America’s beavers in the 18th and 19th centuries, though absolutely lamentable, transformed idyllic places into wastelands, and that merely restoring their populations can cure so much of what ails our parched and eroded lands.

You see what I mean? He loves the book. LOVES it like his toes curl when he stretches out with it on the couch. But its just too darn lovable, and makes those rotten beavers, whom he also says he loves, too lovable.

The poor man is in a quandary.

I don’t mean to suggest that Goldfarb ignores the potentially problematic effects of beavers — the flooded fields and clogged culverts and submerged paths.

But it seemed to me that the author’s confidence that relatively simple, if not always cheap, solutions exist for every beaver-caused problem minimizes the reality that the world into which he — and I — hope beavers will once again thrive is quite a different place than it was when fur companies were decimating the populations.

I understand that some people think of that bygone era as not only different but better. Yet even if you consider as scars the roads and cultivated fields and homes and parking lots that replaced beaver ponds, it is not realistic to act as though these things are unimportant.

I know I know. You thought when I alluded to that tempestuous romance of your college years I was joking or exaggerating in that way I sometimes do. But no. He’s honest to god in a classic approach-avoidance conflict with this book, and possibly with Ben himself. Scouts honor.

There is of course nothing wrong with passion. Indeed it is often an admirable quality, one that encourages so many of us to do good work in the world.

This is a man pulling on his jeans in the morning and thinking maybe things went too far. I recognize the signs.

But I am ever suspicious of the mixture of hyperbole and simplicity that sometimes accompanies passion. Which is to say I’m skeptical of anyone who boasts of all but universal solutions to vexing and complex problems — which, after all, is what very many problems are.

At this point he goes on to describe two similar situations that people get passionate about but are kind of meaningless. He stops just short of mentioning that girl he let get away. There’s nothing wrong with passion. It’s just TOO passionate.

And although I both appreciate and largely share his excitement about what beavers can do for mankind, I believe I would have enjoyed his book even a bit more if was a trifle less breathless in its affinity for the wondrous rodents.

The problem Ben is that you are too positive about the positive thing you’re talking about! He needs more doubt and negativity in his gospel! You’re a trifle too breathless for the man. You need to breathe more. Breathe more.

Something tells me that this man didn’t breathe a whole lot while he was reading. He’s an editor and it shocked and shamed him to read such remarkable prose. You are the writer he always dreamed of being.

No wonder he’s not sure whether he loves you or hates you.

Finally a last visit to our good friend Leopold Kanzler in Austria, who posted this luscious photo of mutual grooming this morning and called it “Die Umarmung” or”The hug”,

So it’s nearly time for grants to start being turned in and thank the lord i finished most of ours before heading into the hospial. The idea this year is a treasure hunt with children searching or pieces of the old map to the “lost key to the waters.” Children will go to participating booths (marked with a treasure map) and receive a ‘clue card’ and a torn piece 0f the map – when they collect all 8 will they can tape them together and read a clue on the back of the map telling them where to find the ‘lost key to the waters’.

Can you guess what it might be?

Here are some images of the ‘clue cards’ we just had printed at moo )30 percent off December sale with free shipping) and hopefully Amelia will make us an amazing treasure map because she loves that kind of thing.

Don;t you just with you were a kid again so you could solve this puzzle? I’ll give you a hint about the :key to the waters”. Shhhhhh
