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

Month: May 2011


Couldn’t resist the impulse this morning, hopefully i’ll add some edits when I have more time. Here’s hoping we never get to see “beaver delicates” again!

Remember Mandy Hotchkiss who earned incredible press by dressing up in a beaver suit last week to remind drivers to slow down at a wildlife crossing? Well looks like she has some like minds in Skip Lisle’s home state. This is a letter to the editor printed at

Sweet Pond: beavers to the rescue?

Let me suggest that nothing be done about the dismantling of the dam at Sweet Pond other than to allow beavers to come in and build a new dam.

Beavers are very skillful engineers and have been known to construct very large, expert dams. They also maintain their work. This would cost the taxpayers nothing. A few lodges would go up in the prime real estate thus created.

The wildlife and fish could return!

What about road flooding? Beavers build a lake only to the depth necessary for them to survive over the winter and to maintain the safety of their lodges. Sweet Pond rests low in relation to the road, anyway.

What about giardiasis, the parasitic disease that can infect people’s small intestine, causing diarrhea and other symptoms? Well, not all beavers carry it — and many other animals, like deer, do. It is never wise to ingest untreatedwater anywhere, whether beavers reside in a lake.

Beaver ponds, interestingly, function largely as water purifiers. I used to live on a Native American reservation where the sewage treatment system and pools were not maintained for a few years. Raw sewage just poured into the creek.

However, when a federal inspector finally appeared, he found that the water tested fine downstream. Then three small beaver ponds were discovered between the plant and where he tested the water. The beavers were cleaning the stream — that is, their ponds exposed the water to the oxygen and light necessary to purify the water.

This became a joke on the reservation as the old Indian who lived on that property said, “I’d been meaning to go out and shoot those beavers someday, but I just never got around to it!”

Similarly, any beavers who appear to fix the dam and restore the pond ought to be left unmolested to do their work.

I used to live in Guilford off Sweet Pond Road and came home from work at midnight. One night, I saw something approaching in the road near Sweet Pond: a beaver dragging a tree far heavier than itself right down the middle of the road.

I stopped the truck. The beaver seemed quite annoyed as he repositioned the long tree, front and back, over to the left side so we could both use the road.

I stayed still watching it drag the tree past the truck. It didn’t even look up at me as it passed.

Let the beavers take care of Sweet Pond!

I am sharing this mornings horrifically blurry video with you so that you can see a plucky beaver swim up with a stick, feel his way through a pile of new willow on the secondary dam, and turn about to do a little poking. He made some repairs and went up to the bank hole where he proceeded to remove a bunch of sticks and mud. I will confess to you now that I have no idea who it was. He was much bigger than the kit I saw last week, (look at his broad  nose in the lower video!) Cheryl says smaller than the beaver she photographed yesterday which suggest to me, (along with the fact that a month of rare beaver sightings has left me very stupid) that we have at least three colony members: our littlest kit who loves to use reeds, at least one of our fat kits that have yet to prove themselves as much good at anything, and at least one adult who brought a huge supply of willow. That’s three. Who knows maybe there are still five?

Beavers are remarkable creatures. You might be tired of hearing that from me but this morning I have something REALLY remarkable about them to share. This is a bit of beaver lore so fantastic and anthropomorphic sounding I never dared repeat it in public before. Even I, who admire them so dramatically more than preschool teachers or paramedics, did not believe it and assumed it was a bit of romantic mythology.

Not so much, apparently.

In the glowingly affectionate book “Beaver Sprite“, Dorothy Richards describes that when the kits were ready to disperse the father beaver took them on a trek, found them a nice new habitat, helped them get settled in, and then returned to the colony. Imagine!  Of course she brought beavers home to eat in her kitchen, so I thought “yes, that and the tooth fairy are nice stories but lets get back to business.” Then I read this same thing in Enos Mills “In Beaver World” which is slightly less whimsical.

Could this possibly be true? It seemed staggeringly unlikely. I realized  almost in passing that all our dispersals have happened without warning or fanfare, but always in periods where we have gone a long time without seeing Dad. Hmm. Of course Dad is harder to see from November to June anyway, it proves nothing, but it disproves nothing either. Last night I got the final data of support that helped me find the courage to report this unbelievable fact.

Tiller Beaver Research Project, Falcon Creek

So this is one of the relocated research beavers of our friends in Oregon who organized the State of the Beaver Conference. So I  asked Leonard Houston, tell me about this old wives tale of beaver parents getting their children settled in new digs? And what do you suppose he answered? “Our telemetry proves it”. Apparently these radar tracked beavers have shown unequivocally that when a kit is ready to ‘launch’ the adults take him out to the edge of the territory (closer to home if the habitat is good, farther if its bad) and get them settled with the start of a bank hole or dam before rejoining the colony. Only Len says their data shows it’s BOTH PARENTS, not just dad.

Would mom go if she had young kits to take care of? Well the way beaver lives work she wouldn’t probably have young kits. She’d be pregnant and maybe have almost-yearlings. So I guess, depending on how far along she was, depending on what time of year kits are born in the region, she’d stay behind, but it sounds like sometimes she’d go help Junior get his start in life.

I guess, from a purely evolutionary self-interest point of view it makes sense to A) make sure you’re offspring moves out of your territory and B) make sure they have a nice place so they don’t come BACK! (Perhaps some parents of adult children could relate. )But still. That is awesome. I love the idea that Dad took our beavers to their new home, where ever it was.  It makes their future seem seem so much safer. Say it with me now. Beavers are SO COOL!

This mornings beaver news will be temporarily interrupted by feathers, but rumor is there will be an AMAZING update to follow. So stay tuned. I thought I’d talk today about Chickadees. These are the tiny, bright, tuxedo-wearing charmers that flitter through your trees and say their own names over and over again so they won’t forget. Here in the Bay Area we have the ‘chestnut backed chickadees’ but in the sierras they have ‘mountain chickadees’ and on the east coast ‘black capped chickadees’. They’re basically the same bird, weighing the same as three whole pennies with more spunk than you might expect from a disney film. In fact chickadees often surprise, which is what I like best about them.

A million years ago in the sierras we had cross country ski’d into a frozen lake that was a campground during the summer months, and now snow filled and abandoned.  It had the hush of new fallen snow and the stiff green smell of interlaced firs in every direction. A lone visitor greeted us, twittering about, and we amused ourselves by tossing it crumbs from our snow-picnic. I suppose he had gotten brave with the steady stream of visitors in the summer, and missed the free handouts. He came closer and closer until I decided to try this:

What does it feel like to hold a chickadee? Well, I can only say that your spirit inextricably falls upwards until your hand suddenly seems to be the very heaviest part of your entire  body. Mind you, I was holding my entire sandwich in my left hand, close to me, and the crumb in my right hand far from me. The chickadee was not impressed by my efforts to present a stable and unthreatening feeding platform, and he quickly tired of the crumb and landed directly on the sandwich itself

(It made me think of that unforgettable Far Side of the killer whales at sea world leaping up for their tiny reward fish from the hands of the trainer, and one wry whale comments, “I don’t know about you but next time I’m going for the WHOLE ENCHILADA!”)

And this belongs on a beaver website because? Well a few festivals back we ended up with a leftover bluebird box (created ironically by the wife of the cyber hero who started this website!) and the bird box came home with us and was installed on the back fence. Over the weekend our house seemed like chickadee central and I was trying to figure out why. Then yesterday Jon noticed them coming and going from the box where a couple has settled and is raising a suitably noise family.

Remember to keep an eye out for what neighbors your garden might have, and maybe you’ll get lucky enough to have a family whose very name is an onomatopoeia!

Okay now you’ve all been patient for the big beaver finish! I received this just now from our own Cheryl Reynolds who was out looking for our beavers this morning.

So as I got to the footbridge a beaver was coming up to the bank hole and then went back downstream. When I got up to the bridge I realized it was mudding the beginnings (finally!) of a dam. I then went around to the farthest cut off tree stump to sit and wait. He came back down with lots of mud and then when he saw me he turned around. We know the yearlings don’t do that, they wouldn’t have been bothered by me. Big boy, sleek fur, lots of mud in mouth. I’m pretty sure it’s GQ, although it didn’t seem quite big enough, but you know how they look in the water compared to out. It was NOT a kit.

Ash, ash —
You poke and stir.
Flesh, bone, there is nothing there—-

Beware

Out of the ash
I rise with my red hair
And I eat men like air.

Look what I found from John Zelanzy of the Trout Conservancy of Montana.

Enclosed is the Trout Conservancy’s requestto help cover costs for education and outreach efforts focused on educating  landowners, future land managers, and community members about using beaver to restore aquatic habitat and water quality and quantity.

Streams throughout Montana and all western states have undergone dramatic alteration since  near-extirpation of beaver in the 1600-1800s. Among the most important impacts on water quality and beneficial uses have been increased scouring energy in spring runoff, less sedimenttrapping,reduced habitat diversity, dramatic increases in channel and streambank erosion, lowered water tables in floodplains, and reduced stream flow during critical low-flow periods.

Public misconceptions regarding beaver and lack of knowledge about beaver management techniques limit the potential for headwaters habitat protection and restoration using beaver. The goal of our educational effort is to help restore beaver on private and public land, as well as to help achieve a “tipping point” where public support for beaver and stream restoration is great enough to encourage more funding for research and where lethal management of beaver is no longer the default approach.

Great work, John! Did they get the grant? Did Montana achieve a “tipping point” of public support for beaver? Well the Wilderness Conservation Society just announced a refocus of their grants towards mitigating climate change with this little gem:

WCS’s work in Western Montana to reintroduce beavers to parts of the Big Hole Valley so that these natural engineers will create ponds to increase summer water storage for fish and ranchers.

I wrote both the WCS and Mr. Zelanzy with friendly beaver introductions and I’ll let you know if I hear anything.
