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

Category: Educational


It’s Sunday, and there’s so much good news to share I’ll be choosy and just show you the very best for now. First there is a nice article following Mike Callahan’s beaver presentation Smyrski Farm owned by the Weatinoge Land Trust.

Maybe the fierce-eyed bald eagle is the national symbo, but beavers — those social, endlessly industrious homebodies — fired the exploration of North America more than any other creature. To get their pelts, traders and trappers moved across the continent years ahead of any settlers.

“They make drastic changes to the landscape,” said Mike Callahan of Beaver Solutions, a Massachusetts-based company dedicated to helping beavers and humans peacefully coexist. “Usually for the better.”

As with the other large mammals that have found the state to their liking — white-tailed deer, black bear, coyote — humans now have to learn to live with beaver. Gone from Connecticut for at least a century and a half, they’re back in force, slapping tails, damming streams, sometimes flooding back yards.

“Native Americans called them ‘little people’ because other than humans, no other animal changes the environment so much,” Callahan said.

When beavers build a dam, that makes a pond. That makes an open habitat in the middle of the woods, where aquatic plants, fish, waterfowl, muskrat and mink can all thrive.

“They’re really great at creating an awesome heterogeneous landscape with lots of biodiversity,” said Mike Jastremski, watershed conservation director for the Housatonic Valley Association.

Beaver ponds help regulate downstream flooding with the newly created wetlands soaking up rain water like a giant sponge.

After a time, when the beavers vacate the premises, the dam deteriorates, the pond flows away, and you’ve got a new habitat — a woodland meadow. A new set of species adapts to that. Eventually, when that meadows grows back to woods, beavers can return.

Callahan now makes his living installing systems to let people and beavers coexist. The only other option is trapping and killing them. There are too many beavers in the state to relocate them.

“They used to move them to somewhere else,” Josephson of the Naromi Land Trust said. “Now, there is nowhere else.”

“They’re sort of like mice,” said Marge Josephson, president of the Naromi Land Trust in Sherman. “If you see one mouse in your house, it means you’ve got a lot of mice. If you see one beaver, you’ve got more than one.”

Hurray for Mike, traveling between states to spread the beaver gospel with other land trusts.  Clearly Mr. Jamstremski did his homework on the topic and understands why all this all matters. We’re not so sure about Marge (who needs politely reminding that its not generally a good idea to remind listeners that beavers are like mice in their house!)

Sheesh!


My mailbox has been ringing with donations all week for our silent auction at the beaver festival, but I’m going to start with the watercolor prints by Robert Mancini  of Melbourne Australia.

He is a truly talented artist  that works to capture the natural world with his prodigious gift. I still can’t believe how generous he was with us.  Obviously his beaver painting got my attention first, but I was thrilled to see the many others he included, of which these are just a sample., all signed and on quality paper. Go look at his website to see how talented he truly is. Thank you Rob, for your generous support of beavers!

There was a rickety bridge I used to cross when I walked across the creek to my volunteer job back in the long-agoes. Every time I did so I began by carefully considering whether  the rotten old thing would be strong enough to hold me one more time.  In the back of my mind I knew I should give up and go the long way – but the long way was very long. And the parts of the bridge without holes were pretty sturdy looking. Eventually I would pick my way across the strongest bits surprised that the thing which looked so worn out still had strength left in it. In all those years I never fell 25 feet to my death and it never failed me.

I’m hoping that our democracy is like that bridge this morning. Meanwhile, let’s talk about beavers.

beaver physBeaver Phys.org has a very nice story about climate change and our favorite topic, so this article about the Wildlife Conservation Society is exactly the right place to start. I especially love the title:

The latest weapons against climate change: The beaver, the oyster, cold water and more…

Beavers, high elevation streams, and oyster reefs are just three of the weapons in the fight against climate change discussed in 14 Solutions to Problems Climate Change Poses for Conservation, a new report released today by WCS.

From re-introduced beavers restoring the water storage capacity of ecosystems in Utah and Washington, to redesigned culverts that accommodate flooding in Upstate New York, the report showcases 14 inventive “real-world” solutions to a warming climate threatening wildlife and ecosystems worldwide.

Solutions profiled include traditional and innovative conservation tools applied strategically to address such as decreasing water availability, increasing risk of flooding and wildfires, rising sea levels, direct effects on species and habitats, and changing land use and human behaviors.

WCS Climate Adaptation Fund Program Director Darren Long said, “We are thrilled to share our ’14 Solutions’ report, and for others to learn from the adaptation work of those whose projects are showcased here. These solutions are on the leading edge of a field where traditional conservation work is no longer sustainable or strategic in light of .”

One of those fourteen solutions was a grant to the Methow Project in Washington, another was building pretend beaver dams in Montana. Go read the report here, and just be grateful there are little steps we can make to  help ourselves, and organizations like WCS to help us do it.

CaptureTime to visit Boston College where Beaver researcher Peter Busher has some interesting desk-o-rations. HDr. Busher hasn’t always been what I call a beaver believer, but he’s always been interested in the animal.  Go to the website where you can see an interactive page that allows you to click on specific items and learn why they’re on his desk. I am currently wondering if this intriguing fact is true:

CaptureYou know I’m already off to examine ALL the beaver chews in our house and compare incisor width. I asked a few experts whether they agree, because it’s nothing I ever head before. Oooh interesting.

Now onto Nebraska where their Ground water festival is in full swing. It’s been going on since 1988 so okay, they have us beat. But I’m not exactly impressed with the activity or the teaching about beavers! (Troubling statements will appear in red!)

Fourth-graders learn of key role of beavers and wetlands in nature

Build, Beaver, Build was a new activity presented by the Nebraska Game and Parks Commission at the Children’s Groundwater Festival on Tuesday at Central Community College in Grand Island.Monica Macoubrie, wildlife education assistant, quizzed Boone Central fourth-graders about beavers and why they are critical to groundwater.

After her instruction, the kids enjoyed making an edible beaver lodge out of pretzels and chocolate frosting.

“We talk about why beaver dams are so important for groundwater and all the other species that use the wetland areas,” Macoubrie said. “Then they make their own beaver lodges. Lodges are different than dams, and we want to show the kids the difference.”

Macoubrie passed a couple of props, including a beaver skull, around to the students. She told them that beavers are members of the rodent family and that the unique orange coloring of their teeth is characteristic of rodents.

Really? Are rabbit teeth orange? Prairie dog?

Scientists classify beavers as keystone creatures because the ponds and wetlands created by their lodges are also used by many other animals and plants. Macoubrie quizzed the students about what kinds of creatures depend on the wetlands created by beavers.

Keystone species are anything that affects other animals,” she said. “Without our keystone species, those other animals would not be as abundant as they are.”

Another reason beavers are a keystone species is the fact that half of all threatened and endangered animals in North America rely on wetlands.

“Without those beavers, we would not have half of those animals,” Macoubrie said.

Which half, the front half?

She said beaver populations are doing well in Nebraska.

“They are considered a least concerned species, so we have a lot of them,” Macoubrie said.In fact, Nebraska Game and Parks officials are sometimes called to help relocate beavers when their dams present a flooding problem for property, she said.

Okay, in a metaphysical way, death IS a kind of relocation. The last relocation.

Marcia Lee, festival coordinator, said Cedar Hollow teachers Ashley Dvorak and Lola Hoover attended the festival with 44 students. Dodge Elementary teachers Michelle Carter, Alma Gutierrez, Amy Mingus and Nikki Stevens brought 67 students. Knickrehm Elementary teachers Sydney Gartner and Diane Meyer attended with 32 students. Trinity Lutheran teacher Wendy Heider brought 11 students.

Overall, 744 students attended this year’s festival with 43 teachers from 19 schools. More than 30,000 students have been educated at the festival since 1988. The Nebraska Children‘s Groundwater Festival has been replicated in 41 states in the U.S., Mexico, Canada, India and the United Kingdom.

The Groundwater festival is a big big deal with a big foundation and financial backers. In Platte Nebraska it is focused on regional issues and makes a huge difference. I can’t exactly argue with that and I’m glad they teach about beavers. Fracking pressures are driving water protections down in the region, and for people to learn more about what sustains them seems necessary. I can’t help be curious how much money fracking donates to these festivals. I’m sure its some respectable amount designed to influence and make things appear rosy.

But let’s face it, the ground water festival needs some better beaver education and activity. I think I’ll just drop them a note.


Beaver benefits are on Utah public radio this morning. Let’s hope that helps his case for Kelly’s visit to the court house next week.

The Beaver: Helping Keep Water On Drying Lands on Wild About Utah

Installing a pressure transducer (inside the white pvc pipe) which is used to measure flow. Restoration treatments are assessed through monitoring water flows.

Beginning as early as the 17th century, beavers have struggled to find safe places to build their homes. Initially, hunters trapped beaver extensively to keep up with the popular beaver fashions in Europe.Then as settlers began moving west, they considered the beavers annoying because of their tendency to cause flooding and damage trees – so the trapping continued.

However, today in many parts of the American West, the beaver’s 400-year-old struggle is fading, because of their ability to keep water on dry land in an efficient manner.

While beavers may not be welcome in most city limits, ranchers and wildlife managers are re-introducing them to rural areas where the benefits of their dams far outweigh the inconveniences.

When Jay Tanner learned of the potential benefit of beavers, he drove to Utah State University and met with scientists and researchers who had experienced success in restoring beavers in the west.

Eric Thacker, Rangeland Management Extension Specialist at USU said, “A beaver dam provides a buffer or mitigation for drought.”

Kent Sorenson, habitat biologist from the Utah Division of Wildlife Resources described the financial benefit of the beavers, “[When beaver manage the dams] our operation and maintenance costs go to zero — they do all the work. They are 24/7 – 365-day maintenance crews that do not require a Corps of Engineers 404 permit.

And that! ladies an gentlemen, is what we call “good beaver press”. Share this site with your friends or nonbelievers because its a good big of persuasion from a pretty rugged source. Hopefully the judge in the McAdams case will accidentally hear it over coffee and waffles this morning. I don’t think it counts as ‘ex parte contact’ since it doesn’t star Kelly or his beavers, right?


 

Another nice beaver report in the form of a letter regarding depredation from the president of Protect Our Wildlife in Vermont.

Off-season trapping doesn’t help

Some of you may be familiar with official trapping season each year, but did you know that trapping occurs all year long under the guise of “nuisance” wildlife control? This unregulated, year-round trapping and killing occurs at biologically inappropriate times when animals like foxes, raccoons and others are raising their young. This means, among other things, animals are left orphaned with little chance of survival when their mothers are killed.

There are no set parameters as to what constitutes a “nuisance” animal. A warden once told me that a raccoon could be defecating in your garden and that could be considered a nuisance and therefore an excuse to kill the animal. There are many non-lethal ways to address wild animals causing damage that don’t involve killing, but the state seems to be mired in a trap/kill/repeat loop. Tragically, beavers are one of the most heavily trapped animals, leaving entire family units broken. Beaver kits stay with the parents for two years so the loss of a parent can be detrimental to the survival of offspring. Water flow control devices, exclusion fencing and wrapping trees are all long-lasting, humane options to address beaver damage.

Not only is this unjustified trapping and killing bad for wildlife, it’s bad for people. Unlicensed, unregistered “nuisance” wildlife control operators can collect payment to trap and kill animals, but these operators are not even required to have a trapping license. This means that they haven’t undergone the trapper education program nor are they familiar with best management practices. Animals trapped and killed as “nuisances” aren’t reported to the Fish & Wildlife Department so there is no data collection or controls in place to monitor what kinds of animals are killed, how many and why. For a Department who is responsible for protecting wildlife for the benefit of all Vermonters, including future generations, this seems to be a lapse in responsibility.

We are thankful for bill, H.262, An act relating to the licensing of nuisance wildlife control operators, introduced by Representative Jim McCullough, which will hopefully close some of these loopholes, if the bill is successful. When unlicensed trappers set leghold and body gripping traps during the warmer months when people are out recreating with their dogs, that presents an unintended threat. A baited trap for a raccoon will just as likely trap a dog or cat. We must emerge from the dark ages and find a better way.

 Brenna Galdenzi, president of Protect Our Wildlife POW

Good letter Brenna! We here in California agree that beaver nuisance depredation is the unregulated, unobserved practice that kills far, far too many beavers. Near as I can tell looking at the text of the bill, H. 262 requires even nuisance trappers to have a license and to show the reason why lethal means are needed  and what will be done to discourage wildlife in the future.

Since depredation takes resources away from EVERYONE in the state, it seems pretty reasonable to ask for these things, doesn’t it?


IMG_9753Yesterday was an extravaganza of beaver support from a huge Earth Day event at the John Muir House. The activity of creating a ‘Martinez Loves beavers’ locket was so popular that we ran out of our 150 supplies by 11 and had to restock by sending Jon home to get backups which we nearly ran out of all over again. The beaver annIMG_9804iversary card was hugely popular and literally signed by hundreds and hundreds of people. Including two city IMG_9939council members.

Our volunteers were hardworking, cheerful and thank goodness had the stamina to keep up with demand. Champion Leslie Mills maintained her inviting cheerfulness long after the rest of us were worn out and ready to pack up the day. As always, Cheryl’s great photos recorded glory perfectly.IMG_9935

Our beaver as Ecosystem posted was a big hit, John Muir and the park superintendent wore their locket all day, April an Alana did beaver puppet IMG_9868shows in addition to drawing some amazing beaver art, and someone told me that they had learned all about beavers from reading friend Rob Rich’s article in the Earth Island magazine!

I talked to a woman who had attended my talk in Portland, children who knew more about beavers than I did when they moved into Martinez, a teacher who worked was the colleague of the mother of the artist doing our art project this summer, and  someone who reported seeing a beaver in San Ramon creek! I thought you would appreciate seeing some  photos of the wonderful, jubilant, exhausting day.

I was planning to share the cool beaver pendants we were donated for the silent auction, but good lord I’m still tired an that’s enough good news for one day. Mean while Brock Dolman and Kate Lundquist of the OAEC were marching for science!

Let me start right off by being all meta and saying might just notice something new this morning. It’s the appearance of our ‘links’ which was kindly updated by a new beaver friend who happened to cross our paths. Christopher R. Scharf is a web designer and avid wildlife photographer who contacted me after the recent Times article hoping to photograph beavers. I introduced him to Rusty took him on a beaver trek and afterwards suggested he might not be adverse to lending a little hand. So Chris spent a couple weekends peering at the funky CSS on this site and tweaking the way links appeared (like that one right back there, watch what happens when you scroll over it with your cursor) so they would be easier for you, the very important readers of this page, to follow.

Because beaver friends come and many mysterious packages. Thank you, Chris!

Websites and technology are so important when it comes to saving beavers. Just look at this film which was made of the recent 4th grade visit to the Draper Utah wetlands by the Mapps lab with the Childrens Media Workshop. They even incorporate our favorite clip from Leave it to Beavers with our friends Suzanne Fouty and Carol Evans. Ahh, Jari Osborne’s masterpiece really is the gift that keeps on giving!  Looks like Kelly visited the classroom first, then students visited his property to learn about the wetlands in Draper, Utah.

I particularly love the teachers in this video, who are patient, cheerful and informed about all the way beavers matter. Not to mention the students, who all deserve to attend their very own beaver festival soon. On Earthday the McAdams family will allow visitors to their property to see the wetlands for themselves. He is doing an expansive, admirable job to keep what matters. Here’s another video slideshow made about the day and sent by the class System Support Coach, Patti White. Why not leave some nice comments so they know how wonderful this is?
