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


I couldn’t help browsing around to see what other fantastic beaver ideas there were in the world. I came across this adorable kickstarter project that is very near its goal. Lucky for us, we still have time to help.

little beaverLittle Beaver Builds a Bed is a short, illustrated children’s book focused on the importance of making things by hand, doing things well, and working together to get the job done. This book will be beautifully hand-illustrated and will be great for kids on an age 3 – 5 reading level. Through the book I hope to connect more kids with the craft of woodworking and introduce them to the value of making things with your hands.

 In this delightful story, you’ll follow Little Beaver as he follows his curiosity about the amazing things his father builds in his woodland shop. Little Beaver will learn a lot about patience, making something from scratch, and will get to build a special project with his Dad.

Gd2de62a3afe8ab80152efcdbf634b424_originalo here to help Katie bring this project to fruition, because we need some copies for our silent auction next year. The children of Martinez have certainly learned something about creating with their hands. These fuzzy little illustrations by Kristen are adorable. They should be prints as well because I bet I know where they would sell nicely.

Meanwhile here’s some fantastic children’s artwork by Caroline Brose, a young artists featured on the Ink and Snow website. I think this needs to be a t-shirt, don’t you?

BroseTrapToon402Big smile for Caroline. Thank you!

I idly thinking how to make our awnings more beaver-y and wondering about whether we might let kids paint our art table awning next year. Since awnings are waterproof it’s a pretty sticky proposition to try and paint one. Look how this artist solved the problem. Jeanette Janson did a beautiful job setting her artwork display apart from all the others at the vintage fair. She’s an artist who got tired of her plain white display canopy used at fairs, etc. So she painted her own.

There were 48 birds by the time she was done and it took her an entire weekend or longer. She ended up with something truly awesome that made her booth completely visible and unique. It was a lot of work. Because if you do the math it’s 40 feet total (10+10+10+10).

But it would be a lot easier with 100 children to help, right?

Every now and then you encounter decisions made by theoretically informed individuals that are so egregious and devoid of common sense, that you just HAVE to write about it. This story about an airforce base in Louisiana fits the bill.

De-watering demolition defends against flooding

BARKSDALE AIR FORCE BASE, La. — Airmen from the 2nd Civil Engineer Squadron Explosive Ordnance Disposal flight detonated explosives under two troublesome beaver dams in the east reservation on Barksdale Air Force Base, July 29.

The process of removing beaver dams is called “de-watering” and is necessary to keep the environment healthy and safe.

 “Beavers will expand their habitat as far as nature will allow, and they will keep building their dams higher and higher if not stopped,” said Gibson. “By controlling the beaver population, we can help prevent flooding and damage to infrastructure. The flooding also drowns the trees. We lost around 10 acres of trees here because of flooding due to beavers dams.”

That’s right. Even though our tax dollars are paying Michael Pollock to do research proving that beaver dams are good for trout and erosion. They are also paying for soldiers to keep their hand in between military assaults by blowing up beaver dams. To keep the environment healthy. Because nothing is healthier than mud, sticks and fish blasted into the air.


It seems instructive to me that no matter what youtube video you watch of blowing up a beaver dam (and there’s a bushel to chose from, believe me) that the blast is ALWAYS followed by hoots and whoops of excited men.

Blowing up beaver dams is the cialis of watershed management. Boys just LOVE it.

Calling this procedure a technical term like the “De-watering” is particularly annoying. As if this extreme action was really for the good of mankind. It’s like calling the economy collapse of 2009 the ‘de-mortgaging.” Or your health insurance rejection a “De-benefitting”. Or  your company firing you a “De-employment” Just don’t come to FEMA for drought assistance when all your water dries up, okay?

Just because you put a DE in from of it doesn’t mean it’s not a stupid idea.

________________________________________________________

I have to mention that this time last week we were already exhausted in a good way from the best beaver festival ever. Honestly, it seems like a world away, but the calendar swears it has only been a week. This year we had most of our expenses paid for with grants, so were pleased that we not only held a very well attended event, but also generated funds for the next one. We have only one final item from the silent auction to get to its owner, and everything is organized and put away.

(Mind you, I have a shrink talk to give at the BAR at the end of the month, so I have to start working now and hope I can remember anything at all except beavers when the time comes.)

 


Are you sitting down? Because this might come as a big SHOCK. But apparently all those years of ruthlessly hunting beavers affected their behavior. I know, get out! But apparently the scientists are saying what we’ve always known, and it greatly interests the BBC.

Beavers’ activity is still influenced by “ghosts” of long-gone predators, study suggests 

A new study suggests beavers are better adapted to diurnal – or daytime – activity, but switched to coming out at night and twilight to avoid hunter-gatherers.

Past persecution could have influenced beavers’ behaviour down through the generations.  The semi-aquatic rodents’ nocturnal activity pattern could be a persisting effect of the spectre of human hunters, who would have killed the mammals during the day thousands of years ago, according to scientists.

Scientists at the University of Antwerp in Belgium studied camera trap footage in the country’s Flanders region to find out if the the beavers had adapted their activity patterns to a predator-free environment.

But extensive footage revealed the cautious creatures continued to be mainly nocturnal and crepuscular (active at dusk and dawn).

The study, published in the journal Mammalian Biology, suggests this could be the legacy of a long period of persecution that began in the Pleistocene epoch (2.6 million – 11.7 thousand years ago), when hunter-gatherers would have used hand-held weapons and gone out in daytime, before the use of animal traps.

The new study points out beavers’ night-time activity pattern may not be optimal for the species. “First, their eyes are not particularly adapted to seeing in the dark,” Swinnen tells BBC Earth.

 “Second, when beavers would be active during the day which is warmer than the nights, they would lose less energy for thermoregulation, which is beneficial. Third, as a herbivore, their food is always present, so there is no reason to forage mostly during the night.”

Now if this doesn’t sound like news to you, you’re in the right place. I’ve been saying this ever since I read it hypothesized by Hope Ryden in Lily pond, which was written around 40 years ago. And she was informed by the writing of scientists of her time who were writing about earlier writing. The headline on this story should be Everything old is New again! And why on earth WOULDN’T our behavior affect them?

In a decade in Martinez we’ve changed how comfortable one particular family of beavers is around humans. Why wouldn’t 1000 years of aggression do the same for all of them?

It’s important to add that in large rich, safe habitats beavers STILL work in the daytime. Our own Lory watched several in Denali park in Alaska.  The area surely wasn’t without predators, wolf, grizzly and mountain lion to name a few. However their primary threat has always been of the bipedal variety, so they adapted their behavior accordingly. Even the fierce nocturnal wolverine, famously lured by beaver meat, was less threatening then humans. I guess because sometimes wolverines aren’t hungry.

But humans were always greedy.

Glorious photos from beaver friend Sylvie Meller this morning of the new generation in Devon. Enjoy.

Wild beavers growing up fast

The news that England’s only wild colony of beavers had given birth to kits was taken as proof that the creatures are ‘thriving’ by Devon Wildlife Trust (DWT) in June.

Now, pictures taken by photographer Sylvie Meller show the young beavers to be healthy and already feeding on riverbed vegetation.

Sylvie said: “They have grown already quite a bit, but are still tiny compared to their parents.

 “Seeing an adult beaver swimming, only its head would come out of the water. The younger the kits are, the more they are above the water.”

So wonderful and heart-breaking to see. I love the idea that despite all the bruhaha and legal machinations, the beaver family is just marching on. After all the media, and DEFRA, and being trapped and tested, the family is fine. Doing what beavers do. It’s fabulous that Sylvie is there to photograph them. Much better than night cams.

I can’t help think about four particular kits that we will never see grow up. I’m sure you can’t either.

 

 


Beavers busy damming Cumberland Land Trust property

TRUST beaver signCUMBERLAND RI – It was just about a year ago when members of the Cumberland Land Trust figured out that flooding on their Atlantic White Cedar Swamp trail wasn’t caused by heavy rains.

This trail off Nate Whipple Highway utilizes a colonial-era cart path along the side of the swamp that crosses a stone culvert thought to have been installed 200-plus years ago.

At first trust members poking around the flood waters last summer simply cleaned out the culvert crammed with mud and twigs.

“Then we came back the same afternoon and it was all plugged up again,” says member Frank Matta. “We thought at first it had been vandalized.”

It was about then that someone suggested beavers. “It hadn’t dawned on us until that moment,” Matta said this week.

Oh those beaver rascals! Plugging the hole you dug in their habitat so that all their precious water didn’t  escape.  You do know that their are answers to this kind of problem, right?

The group has also called in Michael Callahan of Beaver Solutions in South Hampton, Mass. He’s proposing a piping system that will allow drainage through a hole in the dam. The company claims to have resolved more than 1,000 beaver problems in the United States since 1998 by installing flow devices that keep water draining without alerting the beavers. The Cumberland Land Trust is looking at spending about $1,700 for the installation plus a yearly maintenance fee.

Whooohooo! Rhode Island hires Massachusetts! I don’t think we’ve ever had a positive beaver story from there. But here’s a grand example! Remember that RI is an island so the article says that after beavers were trapped out these ones swam through the Atlantic after being reintroduced in Connecticut. Cool.

And I haven’t even shown you my favorite part of the story. Ready?

East Sneech Pond Brook connects the town’s Sneech Pond Reservoir to the swamp then flows east to Pawtucket’s southern reservoir in Arnold Mills.

Sneech pond? Really? Dr. Seuss would be so proud.

And an awesome letter from Ontario in Parry Sound.com, I’ll reprint here in full.

Not necessary to destroy beavers, reader

I read with interest the article that appeared in the July 20 issue of the Parry Sound North Star regarding the washout on Clear Lake Road. According to the article, the washout was caused after the nearby resident beavers were killed, as evidenced by the photos of a dead adult in the ditch and a drowned young.

As an individual who has had some experience with beavers, who are often labelled “nuisance animals” I feel compelled to write.

Beavers are nature’s engineers. They live peacefully in family groups of an adult pair, their last year’s offspring as well as up to three to four infants born early in the spring. The young learn how to create and maintain a dam by mimicking their parents.

It is an acquired skill and one that is learned by trial and error over time. When one or more adults are trapped, as it appears to have happened in this particular case, the young are not yet at a stage where they can maintain a dam properly.

As a result, the dam becomes unstable and breaks, resulting in a tremendous amount of water being rapidly let loose, causing flooding.

Beavers and the role they play in our ecosystems are widely misunderstood.

They create wetlands (which are rapidly disappearing throughout Ontario); beaver activity creates critical habitat for so many other species including fish, otters, muskrat, herons, osprey, moose, bears, ducks, etc. etc. Beavers contribute to biological diversity and regional plant succession regimes; they control the kinetic energy of streams, raise the water table, create canals and generally increase water storage capacity of watersheds.

Mr. Rob Marshall, Seguin Township public works foreman, claims that they hire a trapper to prevent washouts from “nuisance beavers”; however, it would appear that just the opposite happened on Clear Lake Road. Because the adults were trapped and killed, the dam could not be sustained and consequently broke, causing the washout.

In addition, I was informed that a large culvert intended to assist in road maintenance had lain in the ditch for over a year; had it been installed, when the dam broke, there could possibly have been little or no damage done. Instead, I can only guess at the expense involved in the repair of the road and excavating of the culverts; this is taxpayers’ money spent needlessly.

I visited the property of Diane Dow on whose land the beavers had been living peacefully to see for myself the devastation caused by the breaking of the dam.

The site is where three separate watersheds combine into what had been a very large pond – home to many species of fish and animals.

What I saw was muck; I saw a muskrat desperately swimming in a very tiny pool; I saw a mother duck and her ducklings forced to sit in the open and prey to any predators; I saw dead fish; I saw dead water lilies & other vegetation; I heard herons crying desperately searching for fish in the once-abundant pond. The peeper frogs are gone; the turtles are gone. And of course the entire beaver family is gone, either drowned in the washout or trapped. It was heartbreaking.

Quite apart from the environmental destruction, there is another factor involved in this situation (and probably similar ones within the township and elsewhere). The traps were laid in the ditch along a well-used public road and very near a public beach, often travelled by neighbour children and dogs. What would have happened if one of these had encountered the trap instead of the hapless beaver? And the dead beaver was left to rot for three days over the long weekend in July.

To quote from the website of the Fur Bearer Defenders, “Often these issues result in municipalities hiring trappers to kill families of beavers. And while lethal trapping may seem effective, it is only a short-term solution. More beavers will soon come into the area to fill the open niche. This is an especially tragic decision because there are many cost-effective, non-lethal options to prevent flooding from beaver dams”.

As it happens, representatives from Aspen Valley Wildlife Sanctuary and Muskoka Watershed Council are in the process of organizing a workshop for municipalities regarding successful alternatives to control undesirable flooding that may occur due to beaver activity.

The two groups have invited an expert in this regard to head the workshop. The beaver deceiver, beaver baffler and other easily installed devices have proven successful in many regions of Canada and the United States. Last year, one of the programs appearing on The Nature of Things entitled “The Beaver Whisperer” highlighted the vital role that beavers played in our ecosystem and also demonstrated the devices mentioned.

I would respectfully urge the Seguin Mayor and councillors to seriously consider sending representatives to this workshop so that you, as well as other adjacent municipalities can work on implementing long-term solutions that truly work.

It is not necessary to destroy beavers – Canada’s national symbol – and I sincerely hope that this letter will provide more of an understanding of the vital role that this animal plays locally as well as nationally.

At least Vermont has the good sense to question bad advice once in a while!

Commission wavers on fate of beavers

Though the Select Board didn’t pull the trigger on the trapper proposal at its meeting Monday night, members were told a nonlethal alternative, suggested by a licensed wildlife rehabilitator late last year, wouldn’t work in the estimation of an expert from the state Department of Fish and Wildlife.

Chris Bernier, the department’s furbearer project leader, visited the site in June and quickly concluded that erecting an “exclusion fence” or “beaver baffle” at the culvert would be futile.

According to an email from Bernier, that’s largely because the culvert in question serves as the outlet for nearby Berlin Pond and any permanent structure designed to deceive dam-building beaver would be easily overwhelmed by water flows, require frequent maintenance, or both.

“It is safe to say any structure (baffle, fence or combination thereof) would be readily overwhelmed during even moderate rainfall events,” Bernier wrote, noting his “desktop review” of the upstream drainage area revealed marginal storage capacity and “bank full flows” averaging 229 cubic feet per second.

Now we’ve met Chris before over the years, and his advice has been a mixed bag at best. But I wonder if you can guess  what percentage of CDFG wardens contacted about the Martinez Beaver situation warned that a flow device would NEVER WORK. I’ll wait  while you think. 50%? 75%

How about  100%.

Okay Mr. Solutions-only-work-on-easy-problems…we understand your hesitation. But Skip Lisle INVENTED the technique you’re dissing, and he happens to live 100 miles from you. (2900 less than he traveled to Martinez to fix OUR problem nearly a decade ago.) Maybe you could, I don’t know, ask his OPINION on the matter before you decide, in your infinite wisdom, with your beaver 101 education  that this problem can’t be solved?

At the time, John Aberth — a Roxbury resident, college professor and licensed wildlife rehabilitator — gave the board a crash course in “beaver baffles” and “beaver deceivers,” arguing they would be relatively inexpensive to install, easy to maintain and significantly more effective than trapping.

 Swayed by Aberth’s presentation, the board referred the issue back to the commission, which has since obtained a conflicting opinion from Bernier and reluctantly expressed renewed interest in trapping. The request was briefly discussed by board members who did not take any action.

Hmmm, like valiant little salmon trying to swim upstream against a current of bad information. Vermont MAY get this one right with a little more effort. I wrote everyone I could think of and Dr. Alberth for good measure. In the meantime let’s hope that the vibrations of nearby Skip Lisle will shake them into paying attention.

Now for some eye candy.
