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

 Leave it to beaver: Flat-tailed fellow can’t stay out of mischief

Let’s face it, I’m never happy about any article that starts with a photo of a dead beaver. But when you constantly handle sharp instruments you’re bound to pick up a few callouses. Still, even I was surprised by how un-outraged I was by Steve Gilliland’s column today about beaver trapping in Kansas. I guess I’m grading on an 6 year curve, but I get the impression that Steve is about four beers, a copy of three against the wilderness, and a couple of long conversations away from becoming a beaver believer of his own. Of course the chat would have to happen with the right kind of person – not me and definitely not sherri. (We care too much.) Maybe Mike Callahan or Jake Jacobsen? Someone affable who understands the trappers view of the world and could gradually introduce the idea that beavers do a lot of good. Anyway, see what you think.

Our little city owns property just outside town, known as “the city pasture.” There’s a motorcycle race track, several small picnic shelters with tables, slides and merry-go-rounds for the kids and a nice little fishing pond. One morning a couple weeks ago, the city crew stopped by and told me a beaver had taken up residence there in the pond and was chewing trees. The city manager said, “He has to go”.

That day after work, I dug out my beaver traps and equipment and the next evening headed for the pond. I soon found the first evidence, as a small tree along the bank had been toppled, but not too recently. I walked the rest of the main pond bank and found one spot in very shallow water where a den opening ran up and under the bank.

 Beavers and muskrats dig dens into the bank, usually with trough-shaped runs in front of them that form and get deeper over time from their constant trips in and out. An active run will be kept smooth and slick with no moss or any obstructions in it. This den indeed had a run going from it out into the pond but was covered in moss and leaves, showing no recent use. There are two small islands in the pond, and a walk around the larger one found a spot where “the Beav” had recently chewed on a standing tree, leaving a pile of wood chips. I gathered the chips and sprinkled some lure over them, slicked up the bank to make it appear as though another beaver was there too and placed a trap in the water in front, hoping to draw the beaver to the spot again and through the trap.

Maybe I am too sympathetic to deductive reasoning of any kind, but I can’t summon up  horror for this article. I like the fact that he notices things, and his observations about trough-shaped runs fits exactly with Glynnis research on insect biodiversity because of different elevations on pond bottoms from beavers. He goes on to recount accidentally trapping three snapping turtles and one catfish before finally getting his quarry, which was obviously a young disperser thinking the world was his oyster. In the mean time he has some interesting thoughts about where beavers fit in the pond. Remember he is in Kansas which is not exactly the hotbed of ecological understanding. For him to be in the outfields of reasonable as a trapper in Kansas is similar to a man being an environmental attorney for PETA in Washington State.

Five days later, I still found an empty trap. My mind is always going when I trap, processing possible scenarios that I might be missing. Guessing it might be possible for a beaver to come out the hole but slip around the trap the way it was, I shoved the trap up tight against the hole, figuring I had nothing to lose. Two days later, my reward floated on the water in the form of a 45-pound beaver. I reset the trap on the chance there might be a pair of beavers, but the very next night it harvested another big snapping turtle, so I took the trap home.

 I suppose we could all take a lesson from the lowly beaver, pertaining to doing on this Earth what God put us here to do. Just like “the Beav” in “Leave It to Beaver,” that flat-tailed fellow at the park pond could have had life by the tail had he just stayed out of mischief and left the trees alone. He would have been fun to watch and who knows, he might have even gotten named. But as it is … well, continue to Explore Kansas outdoors.

 I hope Mr. Gilliland takes lots of lessons from the not-at-all lowly beaver. I plan on sending a few his way. You never know, the councilman who bought the beaver-buster and his wife have written me back several times interested in flow devices and made sure their public works crew and city manager did as well.

Chip Chip Chip.

Cheryl was treated to some beautiful beaver watching last night on the secondary and got some amazing photos. I thought this morning I’d better just hush up and let her speak.

Oh dam, or damn. This is the cutest picture I have ever seen. My presentation for Randall was all finished but this HAS to go in it. Back to the drawing board. Beautiful work as always Cheryl!

 


Swede bloodied in surprise beaver attack

Taking advantage of the first truly hot summer weekend in Stockholm, Sofie Adde was blissfully unaware that a casual dip would end in blood and stitches after a beaver mistook her thigh for lunch. 

 Sofie Adde from the Gröndal neighbourhood of Stockholm was enjoying her first swim of the summer in the Mälaren Lake when the beaver pounced.

“I went out for a quiet dip and had swum out a few meters when I noticed something underneath the water. Next thing I felt a pain in my thigh and up came the head of the beaver,” Adde, 40, told The Local.

 “It gave me quite a surprise,” the startled swimmer added. “I wasn’t sure what was going on as the beaver (dived) back down and I got scared and swam away immediately.”

 Brace yourselves for the next fortnight of inflamed beaver articles in which Swedes cower to avoid the terrifying rodent menace. Of course this beaver got away so we can’t actually be sure it was a beaver and not an otter…but at least Adde was a good bit braver than the fishermen from Bellarus.

Following the attack, Adde had to have stitches and a tetanus shot. She doesn’t harbour any ill-feeling towards the beaver, however, whom she claims she has seen before.

 “I’ve been down to the lake several times and I’ve seen this beaver in the past. There are a couple of beavers there and it is very unusual for something like this to happen.”

 “The bite wasn’t particularly painful and to be honest it was more funny than anything else.” 

Now there’s a heroine with a sturdy heart and a pretty plucky constitution. Adde send us your address because you get a beaver tshirt.

Didrik Van Hoenacker, a biologist at the Natural History Museum, laughed when he heard of the attack.  “She must have had bad luck and collided with the beaver. It’s not like they normally lurk in the water,” he told Aftonbladet.

Ahh Didrik! You are such an amazing counterpart to the panic button all the world wants to push when it comes to chomping terrible beaver-sharks!  Nicely done. Are you  and Adde the only level heads in the country or is this a national thing?

Beavers are just like other wild animals as they get defensive but it is rare to even get that close to them,” Magnus Enquist, a professor in animal behaviour at Stockholm University told Aftonbladet.

Sigh. Maybe I will move to Sweden. Maybe we all should.

Beavers of Martinez

Join Heidi Perryman, Founder of Worth A Dam, for a talk on the Beavers of Martinez. Dr. Perryman shares the story of how one beaver family won over the hearts of the people of Martinez. This North Bay community took a crash course in beavers when a mating pair moved into a downtown stream. Concerned that their dam would cause flooding, the city proposed killing the beavers, but resident outcry encouraged them to try humane solutions instead. A flow device was installed at the dam and this controlled pond height, allowing the beavers to safely remain. Heidi Perryman is part of the Occidental Arts and Ecology Center (OAEC) WATER Institute California Working Beaver Group, whose mission is to promote understanding of the importance of healthy watersheds. Dr. Perryman recently co-authored a paper on the historic range of the North American Beaver.

Sure would be nice to see some familiar faces in the audience!


I got unreasonably excited when I saw the title of this article, but my hopes were pretty quickly dashed. Apparently beavers are ‘superheroes’ because they can close their nose and ears underwater and open their eyes with a built-in goggle. Not because they change the ecosystem or save the water or increase stream complexity.

Thinking Outside the Classroom: Beavers — the superheroes of the animal kingdom

Summer has finally arrived and with it comes warm weather, budding flowers and the chance to witness the elusive beaver — superhero of the animal kingdom. Next time you find yourself outside enjoying summer in the mountains, look around. If you know what to look for, you may be able to spot this fascinating creature.

Beavers have numerous superhero-worthy skills and adaptations. They are especially skilled underwater. They have an extra set of eyelids that are transparent and act like goggles so they can see underwater. Plus, their ears and noses have valves that they can close before heading underwater.

They’re able to remain underwater for up to 15 minutes and use their tails as rudders to help them swim. Working underwater is made possible by their long front teeth which stick out so they can close their mouths and not swallow water as they work. The beaver is second only to humans in their ability to change the landscape around them. While we often don’t have the opportunity to see them in action, rest assured they’re always up to something.

Yes we can never see what beavers are doing here in Martinez where folks line up by the hundreds to watch them, but we know they are ALWAYS UP TO SOMETHING. Like congressmen or tax attorneys. No mention of the fact that when beavers change the environment things get better and when man changes the environment – well not so much. Did you  notice the name of the science camp where the author teaches?

Cheryl Brenner is a camp counselor at Keystone Science School.

Do you think Cheryl devotes a paragraph to explaining the name KEYSTONE and how it relates to the KEYSTONE SPECIES that is the beaver – and that THIS is what makes it a superhero? Oh, silly silly reader. Of course not. She has more important jobs in mind. Like this.

A beaver’s tail just might be its most valuable attribute. While the tail is good for swimming, it also plays other important roles. During the winter their tails are used to store fat for energy. The beaver’s tail will become long, round and fat similar to a rat’s tail.

Got that? The beaver tail turns into a nutria tail over winter when they live off their own fat. Don’t need a food cache when they always have some beaver tail to rely on. This must be why we always see those photos of beavers breaking ice with their rat tail.

Gosh, I want to sign my children up for that SCIENCE camp! What little naturalists they must produce! My children could learn all about how the earth is only 6000 years old, that duck eggs are flammable and that you can never get pregnant if it’s your first time.

Actually, I’m not sure the title is correct. They may indeed be outside of the classroom – but after reading this I’m not sure anyone’s thinking.
