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

Category: Beaver Rehabilitation

A collection of articles and videos on rearing orphaned kits.


For me, the most powerful part of the state of the beaver conference, was hearing Sherri Tippie talk about stumbling into her role as the top beaver relocator in the united states. For nearly a quarter of a century, Sherri has been the go-to voice on beaver relocation. In the past few years she is more interested in beaver management than relocation, and when consulted she first talks about flow devices, wrapping trees and installing beaver deceivers.  Her pragmatic affection for these animals – and willingness to have her life completely transformed by them – both thrilled me and made me feel deeply relaxed. When I wasn’t shedding tears or covered with goosebumps at her talk, I felt  strangely like a child falling asleep in the back of the car — completely assured of security and knowing the adult in the front seat would get me home safe.

Beavers and their advocacy are in good hands with Sherri. I thought the best way to share the experience was to give you your own. Accept my apologies for the audio but you don’t want to miss this.

Sherri still considers herself a hairdresser by trade, and doesn’t charge for relocation. She works closely with state parks and fish and wildlife and has generally earned a reputation as both compassionate and competent. She has a literal bastion of friends and supporters that she teaches to operate hancock traps and monitor flow devices. Her book on ‘Working with beaver’ was recently published by the Grand Canyon Trust and is an inspiring, practical read and a major achievement.

Several times during her talk she spoke about being personally affected by the beavers in her temporary care – an injured animal that had stood up to say goodbye upon release – a badly treated beaver that a zoo had rejected as ‘vicious’ that came to love and trust her almost immediately. Sherri said firmly that she always tells beavers what she’s going to do before she does it, and they almost always calmly cooperate. She emphasizes that each beaver is an individual, with  unique habits and preferences.

Sherri uses both experience and intuition in her work with beavers. She said when you’re trapping beavers you can’t do anything else, because you have to be there the next morning without fail. She remarked that she used to use apples to lure beavers into the hancock traps, but found the drive in her small car with a gaggle of  gassy beavers a little uncomfortable. Now she covers the traps with leaves, so that the beaver can calmly enjoy a meal while he’s waiting for her arrival.  She described having a ‘feeling’ about how many beavers were in a colony, and when the last member of the family was trapped. Interestingly she said the father was often the first, and often found with kits in the cage.

Mom was usually the last.

if you need more proof of her startling attention and compassion for these remarkable animals, I just received a note from her about the ‘beaver valentine’ saying:

Just opened this. Thank you so much!! What a perfect beaver. Hey, is it just the beaver I’ve seen or have you noticed how they sort of hold their little finger up when they’re holding or eating something? 🙂

My goodness, I hadn’t noticed that before. but you’re absolutely right! Thank you for your courage, compassion and common sense. The world is a much better place with you in it – and not just for beavers.



One of my favorite things about this weird pursuit of all-things-beaver is the way that it seems to lead to a hundred other things. Take the word “Crannog‘ for instance. Paul Ramsay mentioned it casually (as I suppose any Scotsman might) on the Save the Tay beavers facebook page yesterday and I had never seen it before. I went searching for the definition, which wikipedia tells me is “An artificial island, usually built in lakes, and most often used as an island settlement or dwelling place in prehistoric or medieval times.”

Interesting. Turns out Ireland and Scotland have a host of these, historically defensible spaces for Robert-the-Bruce types or other suitably heroic figures that might one day inspire a future Mel Gibson film. So underwater archeology is a fairly well-funded pursuit to look for traces of earlier times and show the world the prominence of the early Scots.

Guess what they found in Loch (Lake) Tay in 2008?

{Mind you, one of the arguments against reintroducing beavers in Scotland  – besides the oft-repeated ‘they’ll hurt salmon” argument and lesser known “beavers are icky” treatise – is that beavers aren’t really native. The doctrine goes something like “There are no beavers there now [because all the beavers were killed by the 1600’s]. That was a really, really long time ago and how do we know its even true?”)

Well, here’s how you know.


Evidence of Beaver Chew: Scottish Trust for Underwater Archeology


That picture on the right is a beaver chew that has been preserved underwater for 4000 years (which for those of you following along at home is around the time of the Exodus of Moses.) It turns out that the pile of sticks they got all excited about being an old Crannog construction was actulally a beaver lodge. The first carbon testing placed the logs as being nibbled way before the birth of Christ. Later reads have marked parts as much as 8000 years old. (before Socrates, before Gilgamesh, before the pyramids, before bronze, and before the start of the Great Wall in China.)

Let’s just say that beavers belong in Scotland and belong in the Tay and leave it at that.

For the second, closer to home, definition, we turn our attention to the Ventura River, important to our quirky ‘historical beaver range’ pursuit because it was an area beavers were famously said not to have been native.

There is one questionahle record of beavers occurring near the coast of southern California along the Sespe Riwr in Ventura County. This record, a single skull of an adult male said to have been taken in .May, 1906, formcrly ~was in the collection of Dr. ,J oh11 Hornung and now is in the California Museum of Vertebrate Zoology. Because of the arid nature of the country it seems improbable that beayers eyer occurred extensiy in this area within historic time at least.

Donald Tappe

So Tappe thought the skull found was a ‘fluke’ and the  pictograph was a ‘fluke’ and there was no reason to believe that beavers, who lived successfully from Alaska to the Rio grande, could have ever plied their twiggy trade as far south as Ventura.

Meet author Jan Timbrook who is a curator for the Santa Barbara museum of natural history. Her book ‘Chumash Ethnobotany” has some very interesting things to say about beavers:

“A willow stick that had been cut by a beaver was thought to have the power to bring water. The Chumash would treat the stick with ‘ayip ( a ritually powerful sbustance made from alum) and then plant it in the ground to create a permanent spring of water.”

Jan Timbrook, Chumash Ethobotany p. 180

Don’t you just love that sentence? Thanks, Jan.  Maybe I’m just an old pagan at heart but doesn’t it just seem possible that planting a beaver chew would make water spring? I went looking for the quote and saw that the reference is already up on the Sespe Creek page at Wikipedia. Go read Rick’s excellent summary so far.  I am reminded that a long, long time ago, when we were camping at Lassen National Park and enjoying the Kings Creek Meadow, we saw on the map that the creek started from a spring so not far away and thought we’d explore. We hiked up a hill to where water just seemed to pour out of hole in the ground. Curious, I put my hand in the hole to feel for myself and touched this burst of water coming out of the earth, that pushed past my fingers and rolled down the hill and winded through the meadow and later became the Kings Creek Falls.


Sometimes you can touch very small things that go on to  become powerful. Just sayin’

UPDATE:

I was off this morning to film some ‘new years resolutions’ at the beaver dam for PATCH. Cameraman John Beck of Sideshow Video did a great job and was very impressed with the local fauna. I told him our top resolutions were (1) Three kits grow up healthy! (2) Worth A Dam continues to spread the beaver gospel and teach other cities to follow Martinez example. And (3) our Beaver Festival IV is the best ever! (I also did my best to convince him to come back!)  After he left me he was headed off to video the mayor’s new years resolutions for the town so I told him to say ‘hi’.

UPDATE II:

After writing about the fantastic River Discontiuum paper yesterday I contacted the primary author to praise her work and invite her to the beaver conference. I also let the ‘gang’ know about it and Michael Pollock persuaded Len Houston to invite her to speak. She’s lacking funds to get there so I’m still hoping a big whoosh of grant money will come her way. Today Science Daily picked up the story!


We had some visitors from Cupertino last night who wanted to see the beavers I spoke about on Saturday. They got an early showing of our biggest kit and dashed off to Lemon Grass for dinner, leaving regulars Jon and Jean to watch and see what might happen next. The two larger kits appeared from upstream, and the smaller one (who isn’t that small anymore!) came from downstream. They engaged in some nuzzling, pushing and wrestling and then settled down to some fun with the flat board that has been floating in the water for a while. To the great delight of their audience, they chewed on it, nosed it, pushed it, and generally had a ‘tug-of-board’. It was a great show!

It has been worth noticing how our beavers interact with ‘processed’ and cut wood. Sometimes people see sawed branches on the dam and assume that we have put them there. The truth is that cut branches often appear at the dam because the beavers are perfectly willing to pull them out of the creek or off the bank and use them for building material. They aren’t picky. We’ve seen them use plywood, traffic cones, beer cans and plastic bottles to  stop the flow. Audrey Tourney, founder of the Aspen Wildlife Sanctuary, wrote about beavers she was rehabilitating in her home who used newspapers, towels, foot stools and coffee mugs to build little structures in her living room.

Necessity is the mother of invention! But I’m pretty sure beavers are its children!

There are a few tickets left for tomorrow nights John Muir Conservation Awards, which will honor Jay Holcomb of IBRRC, Nature Bridge, The Lindsay Wildlife Museum, and our friend Mike Callahan of Beaver Solutions. It will be hosted by Shelton Johnson, the dynamic park ranger from the Ken Burns series. Even our friend Susan Kirks of badger fame wrote about it. (Shhh! Don’t tell Mike or Skip that she accidentally turned them into the same person!) If I were a beaver supporter I would go to show your enthusiasm for the conservation community, drink a nice chardonnay and eat delicious catered treats and buy a signed copy of Shelton’s new book.

It goes without saying that you meet the VERY BEST SORT of people at these events.

And surely all God’s people, however serious and savage, great or small like to play. Whales and elephants, dancing, humming gnats, and invisibly small mischievous microbes—all are warm with divine radium and must have lots of fun in them.

—John Muir, The Story of My Boyhood and Youth


So my brief obsession with superciliary vibrissae lead to Sherri Tippie sending me some early kit photos that showed they were present from a young age. Mystery solved, but ohhh looking at these photos has caused such a grand commotion of oooohing and awwwwwwing among Worth A Dam members that we are incapable of forming complete sentences. I thought I’d share the source of my affliction with you, but first, the answer to the mystery, so we can lay that to rest. Look at those wiry black hairs above the eye. Not as stiff as an older beaver and certainly the sense isn’t as developed, but those are vibrissae.

Okay now that we’re done with that mystery, check out the entire photo. Remember Sherri is the top beaver relocator in the country so she often ends up caring for or raising kits/orphans. In this picture her friend Chris is holding a week old kit. Look at that tail against her wrist! . I’m thinking a visit to Colorado next June is in order?

Sure grown-ups and skilled professionals can manage to hold a beaver. But how difficult is it? Wouldn’t those incisors take out a finger? We are constantly meeting people (usually trappers) who tell us how vicious beavers are. I guess she’s holding that kit a special way or something to make it harder to get a dental grip?

Meet Anna R. who is 8 in this picture. Sherri tells me that when she was 5 she became cheerfully obsessed with beavers. Her dad says she used to walk around the family home repeating “Sherri Tippie! Sherrie Tippie! Sherri Tippie!”. (I know the feeling.) Even though she was too young to help with relocation, she wanted to be involved. This is such an traffic-stopping photo the police should be called. Here’s another one in case you want to see Anna and the beaver smile.

Gosh those are lovely, thank you so much for sharing! And just in case you think we are just bunny huggers around here, I’ll offer some intellectual stimulation as well. Sharon Brown of Beavers: Wetlands and Wildlife lets us know that her letter to the Buffalo News.com was printed in Thursdays issue. Remember the nice article about some researchers noticing that the beaver dam in Woodlawn Wetlands was actually helping water quality and restoring the stream? I wrote them that this wasn’t unique to Buffalo and that if New York could allow more beavers to improve the watershed we’d all be better off. Sharon thought so too

August 26, 2010, 6:54 AM

Thanks for Gerry Rising’s refreshing look at Woodlawn’s wetlands in the Aug. 15 News. Yet negative references to these oases of life still abound—i. e. recent comments about “draining the swamp” of D. C. government—even though wetlands are rated as the land’s best life-support system.

Luckily, we no longer need sacrifice wetlands benefits to prevent road flooding as the modern beaver flow devices are very efficient and cost-effective. Last summer our educational nonprofit sent a team (an engineer and me, a biologist, who were both born and raised in Buffalo suburbs) to Orchard Park to consult with the town engineer and highway superintendent about an installation in Birdsong Park. We can have win-win solutions.

Because beaver dams accentuate the normal filtering function of wetlands, often 90 percent less sediment is in the water downstream. This means less expensive treatment is needed at plants to produce drinking water. Plus, a series of dams keeps water on the land longer and slows the flow of streams, resulting in fewer droughts and less costly flood damage downstream. As such extreme weather events increase with climate change, the beaver can be our ally.

Marshy wetlands are, or will become, peatlands as dead vegetation accumulates underwater. Peatlands are the best ecosystem for carbon storage, but draining them allows the peat to oxidize and release carbon dioxide, the major greenhouse gas. It costs people from $10,000 to $100,000 to restore an acre of wetlands, but the average New York beaver family impounds 15 acres—and works for free.
