I guess our real Forefathers were Furbearers…

Picture4Let’s face it, America was founded on the backs of beavers. Fur Trappers drove the exploration down our rivers starting from  Plymoth Rock, Charleston, Newfoundland,  and everywhere in between.  If there hadn’t been money to be made from their important fur we would have quickly lost our shiny “New World” smell and everyone would have gone somewhere else where the beavers might be.

This holiday is as much about their value as it is about our independence. Because there would never have been ONE without the OTHER.  If we had ended up looking for beavers somewhere else our independence day might have grown out of Canada or Peru or whatever landscape provided enough beaver for us to feel we deserved to be treated as equals.

You think I exaggerate? Here’s how the beaver population was doing in Ohio just three years after the declaration of independence was signed.

Picture3Beaver were so important to the new land we were trapping them as fast as we could. When one digs even a little deeper to understand our origins, beavers are at the roots of our government, laws, economics, geographic boundaries, and even our colorful history of race relations. Take a look at this quote from Captain Simeon Ecuyaer at the Siege of Fort Pitt in 1783,

CaptureSo I guess it’s fitting that Minnesota decided to decorate the fourth with a Beaver-trapping article this year. It turns out that in every meaningful way, our real forefathers were the furfathers who paid for our independence literally with the skin off their backs.

Animal trapping programs keeps drainage ditches clear.

Tim Worthington pulls a beaver from a trap on Wednesday in Grygla, Minn.

Worthington is one of dozens of trappers across northwest Minnesota who participate in nuisance animal trapping programs, which pay trappers to remove critters that cause damage to infrastructure.

 Trapping beavers in particular keeps drainage ditch systems functioning properly as dams built by the animals block water flow and can cause it to backup onto nearby land–sometimes resulting in damage to farmland, officials in multiple counties said.

 County and township government boards can offer bounties for the animals, which range from $20 to $50 for beavers and 50 cents to $3.50 for gophers.

The real irony is that counties are paying trappers like Worthington to make the creek more silted, fishless, and barren. Likewise, the newly established America was so excited to see how many resources it had that it quickly used them all up and created instead a dystopian of land of dry rivers, little game and withering fish stocks.

Of course, when that tap ran dry there was gold to keep us going, and then industry, and then oil. I’m sure learned by now not to use up all our resources, right?

 USDA exploding beaver dams to benefit trout

VILAS County – WI

Wildlife Services Project Leader Kelly Thiel directed the removal of the dam by blowing it up with explosives.

“The purpose of our work is to create a free-flowing stream for the benefit of the trout to be able to migrate up and down,” Thiel says. “If you have beaver dams in there, they can’t migrate, they’re locked in. To have a self-sustaining stream, it needs to be free-flowing.”

 Trout struggle to travel, spawn, and live without those cold, free-flowing streams.

 The U.S. Forest Service and Wisconsin DNR decide which streams Wildlife Services will clear. Of the approximately 1,500 miles of streams that Wildlife Services clears in northern Wisconsin, most of them are high-quality trout streams.

 The work leading up to a particular blast can take months or years. Wildlife Services surveys beaver populations on streams. Then, once it selects a stream for clearing, workers trap all the beavers near the dams in the spring or early summer. It blasts about 150 dams each year.

 ”This stuff detonates at 23,000 feet per second,” Thiel says, stringing a cord between containers of explosives.

 It took about three pounds of explosives to blow up this dam on the Little Deerskin River. Workers placed them strategically and double-checked all the equipment before clearing other people from the area and taking cover with a remote trigger.

 The explosion sent tree limbs, water, and other debris dozens of feet in the air.

Those lucky trout! Gosh,  I bet that water is so crystal clear afterwords when all that debris falls back into the stream. The fish must LOVE it, I mean not the baby fish that were hiding in the side sticks of the dam obviously because they were blown up, but the other fish that survive the falling limbs and rocks, they must love their new gritty home. And the predators must love it too because even after fish stop falling from the sky, there’s no cover left for the survivors. Easy pickin’s.

Ironically yesterday was the LAST day for Wisconsin to receive public comment on their truly disabled fishmisinformed beaver management plan. You remember, the one where they think even though research says beavers help trout in the wacky west, Wisconsin fish are weaker and their conditions are harder, and so they must be saved by painstakingly killing beavers and blowing up dams. I and others dutifully sent them comments containing actual science, but they will obviously ward it of with their powerful information-resistant shields and continue doing what they do.

At least USDA will get to keep having fun. For them buisiness is booming. BOOM BOOM BOOM!

Here are my submitted comments in case anyone’s interested. I was trying HARD not to be too sarcastic, but the last paragraph is my favorite.

Beaver Management Plan

 I’m interested in the research that has lead you to believe trout in Wisconsin function differently than trout in Utah, Colorado or Oregon. I’m surprised that no one in the audience of your webinar asked about this, or wanted to understand why you think the principles of hyporheic exchange operate differently in the badger state then in the west. Current research emphasizes the hydraulic pressure of water behind beaver dams push that water downward and promote exchange of groundwater into beaver streams, making them cooler.

 It surprises me that there is so much faith in the Avery study noting the co-occurrence of dam removal with trout population improvement. Obviously correlation doesn’t mean causation. A cursory review of the literature and periodicals of the time confirm that there were significant other changes to the watershed during that period, that could easily have affected fish health. To assume that this is reliably due to the reduction in beaver seems naïve and ahistorical.

 I was confused to hear that Wisconsin believes the population of beaver went up historically before this program was implemented, until I realized you were referring only to the baseline of the 1900’s – then it made sense. I’m not sure why you ignored the significant beaver population that existed before then. The fur trade brought the French to your state as early as the 1600’s I think, and obviously natives lived with beaver abundance long before that. In 1621 Samuel de Champlain described America’s pristine landscape and exclaimed that beaver occupied “every river, brook and rill.” Surely given the waterways of Wisconsin your landscape was no different. Your beaver population must have been prodigious, much, much higher than it was even before you instated the beaver management plan. If beaver really couldn’t co-exist with trout why didn’t the Dakota Sioux or Ojibwe complain about the abysmal fishing conditions?

 The attached study completed recently looked specifically at the issue of trout passage of beaver dams, and found that natives like brook and cutthroat passed easily in both directions, while nonnatives had more trouble. Are you suggesting that Wisconsin has fewer native trout? Or that the trout it has are disabled in some way?

It is regretful that when the issue of ‘protecting resources” was discussed in your presentation, you seemed fairly disinterested in the most impactful one you take for granted; the one that creates habitat, increases invertebrates, sequesters carbon, and stores water. As I just returned from presenting at the chapter presidents meeting at TU specifically on beaver and trout. I want to suggest that you select just one stream as a control to study what happens to fish population if you stop trapping beaver.

I think the results would surprise you.

Let’s cleanse the pallate with two lovely photos from Robin in Napa showing the barren ruined habitat that beavers leave in their destructive fish killing wake.

Beavers Unlimited

Just in case you’re not sure I’m telling the truth about four kits, here’s the proof. Junior comes from the left for size comparison. One of the kits is a little meanie. I’m waiting for mom or dad to straighten him out.

We didn’t have to wait long to see all four. Hoping they agree to stay upstream through the fourth.

Now, as promised we can finally return to the fantastic Beaver article from Ducks Unlimited. It’s definitely worth our time.

Understanding Waterfowl: Beaver Ponds and Breeding Ducks – Growing beaver populations have created an abundance of high-quality habitat for waterfowl

“We have mined the northland, not for wheat, not for gold—but for fur. Now the fur seed is gone.”

Those words were spoken in 1938 by Ducks Unlimited Canada’s first general manager, Tom Main. He was relating his ideas about how to resolve the challenges facing waterfowl as DU began its first year of operation. Main and many others believed that beaver ponds were an integral component of the original habitat that once produced sky-darkening flocks of waterfowl. By the time DU started its conservation work, however, nearly all the beavers and the millions of ponds they had created along the continent’s rivers and streams were gone.

 Research has verified that beaver ponds provide important habitat for waterfowl. In a large study conducted by DU in the Clay Belt region of Ontario, the most abundant breeding duck in beaver pond–rich forests was the mallard. Other common breeding ducks on beaver ponds include cavity-nesting wood ducks, hooded mergansers, buffleheads, and common goldeneyes. Beaver ponds also provide breeding habitat for American black ducks, blue- and green-winged teal, American wigeon, and ring-necked ducks.

 Beaver populations have now expanded across the United States. In many areas, especially in the West, beavers are increasingly viewed as key partners in the restoration of diverse plant and animal communities. Beaver ponds provide vital habitat for many species of fish, amphibians, and birds while also conserving threatened water supplies and moderating downstream flooding.

 But what effect do beavers have on continental waterfowl populations? DU and others have long chronicled and fought the loss of wetlands important to waterfowl. Despite all our efforts, the net loss of wetlands has continued and even accelerated on the continent’s most important waterfowl breeding, migration, and wintering areas.

 As natural wetlands have declined, man-made water bodies such as reservoirs, storm-water retention basins, borrow pits, and golf course ponds have increased on the landscape. Many man-made ponds and lakes are of limited value to waterfowl, although they do serve some wetland functions. DU and its conservation partners restore, enhance, and protect high-quality natural wetlands that provide crucial habitat for waterfowl and other wildlife. As nature’s wetland engineers, beavers are in the same business, and they do all the work themselves.

Beavers truly are a partner in wetlands restoration and maintenance, just as Tom Main had hoped they would be over 75 years ago.

High praise from a powerful lobby. I’m sure a lot of us might have mixed feelings about DU. (They want lots and lots of ducks to grow up big and strong so they can go out and shoot them.) But DU has done literally more wetlands restoration than we can imagine. They put their money where their guns are, and as a result they have saved many of the very species they are interested in hunting. They really are conservationists. Not my kind maybe, but conservationists all the same.

And they love beavers because they help them do this work. And that’s a big deal.

Not to hog all the camera time, Rusty sent a wonderful photo this week of an otter truly enjoying all that Tulocay beaver pond has to offer.

Just Desserts for beavers

   Posted by heidi08 On July - 1 - 2015ADD COMMENTS

There are not one but TWO awesome pieces of beaver news this morning. I’ll start with the pièce de résistance, a phrase which literally means the thing with staying power. Because that’s what this is. Really.

pollockMichael Pollock sent it to me yesterday on it’s glorious release.  He said getting out 1.0 was grueling and he was still seeing typos, but he asked me to give him thoughts about 2.o down the line.  Check out the title photograph for which it credits the Worth A Dam FOUNDATION.  We would have liked Cheryl’s name too but I’m happy we got the website. And this is exactly the kind of place we want our photos to be. Just read for yourself.

Beaver as a Partner in Restoration

More and more, restoration practitioners are using beaver to accomplish stream, wetland, and floodplain restoration. This is happening because, by constructing dams that impound water and retain sediment, beaver substantially alter the physical, chemical, and biological characteristics of the surrounding river ecosystem, providing benefits to plants, fish, and wildlife. The possible results are many, inclusive of : higher water tables; reconnected and expanded floodplains; more hyporheic exchange; higher summer base flows; expanded wetlands; improved water quality; greater habitat complexity; more diversity and richness in the populations of plants, birds, fish, amphibians, reptiles, and mammals; and overall increased complexity of the river ecosystem.

It starts with a review of the hydromorphic and geological effects of beaver dams, then talks about filtration, groundwater and biodiversity. Honestly. for the beaver nay-eayers on your list, this is a big dose of science from the heavy weights FWS, NOAA, and USFS. Even if you can read nothing else, take a look at the first chapter because it says literally everything you know to win the next five arguments you have about beavers.

Chapter 1—Effects of Beaver Dams on Physical and Biological Processes

Beaver impoundments change the spatial distribution of water (groundwater, pond, or stream), as well as the timing of its release and residence time in the watershed. Beaver dams impound water in ponds and pools, and these impoundments slow the flow of the stream; this holds the water within the stream reach for longer periods and can increase base flows (reviewed in Pollock et al. 2003). Indeed, some perennial streams transform into intermittent and/or ephemeral streams following the removal of beaver dams (Finley 1937, Wilen et al. 1975).

Conversely, reintroduced beaver have transformed some intermittent streams back to perennial streams (Dalke 1947, Pollock et al. 2003), and recolonizing beaver have transformed slightly losing streams to gaining streams ((Majerova et al. 2015).

Honestly every ecologist and politician needs to read this from cover to cover. It ends with first hand case studies of watersheds where beaver were introduced. And describes the successes they observed. I already told Michael it needs a section on restoration in URBAN streams and he says he lobbied for its inclusion but was denied.Thus far. Another something for version 2.0.

At the end is a list of resources for answering any burning beaver question that might arise. And guess what’s first?


That’s right.  Listed before the established forefathers of Beaver Solutions and BWW, the little upstart crows of beavers from martinez have first place in the queue. Along with the cover placement. We are the Alpha and the Omega of living with beavers. Could there be a better sign that we are doing the right thing? Not for me there couldn’t. (I mean another thousand readers couldn’t hurt, but I’d rather be the GO TO spot when folks have burning questions than anything else.)

Honestly the whole thing is such a useful, instructive, science-based labor of love that it will take me weeks to fully read. I did my best to splash its announcement around the four corners of the internet, but feel free to share with your unpersuaded friend(s) of choice. What a fine ending to June!

I think I’ll leave the DU article for tomorrow. But if you want a sneak peak here it is.

The yearly beaver census

Do you know that feeling that Christmas night when you’ve already opened all the presents from all the relatives and been excited and/or disappointed all day in regular intervals. And after you reach way back in the pile to get your last aunt’s or second cousins gifts you find ONE FINAL PRESENT with your name on it. A present that you never knew about! A sudden opportunity to increase your haul and erase the disappointing socks or whatever you never wanted in the first place. You thought christmas was over. And here it is suddenly starting again!

dice_shutterstock_27724330Guess what Cheryl and Jean saw four of yesterday? I’ll give fouryou a hint. It has fur, ears and a tiny tail. That’s right they saw FOUR kits instead of the lucky three we thought we had. Four is a lot! We haven’t had that many since 2008. It’s been seven long years since we had four new kits to fuss over and worry about. Here is one of our favorite mornings of all times, before the city decided to kill the beavers, before Worth A Dam, before I knew anything about websites or beavers.  This was so long ago that I don’t even have the footage anymore, I didn’t know how to save it back them. We were just watching something wonderful in the town where we happened to live.

Four is the product of a strong healthy mom and a calorie-rich habitat, which I was starting to think the beavers had worn down. Especially since we only got a single kit last year. Encroaching phragmites or not there must be some  feeding going on, because a beaver that has four babies is well fed. That brings our current count to NINE! Mom, Dad, 2 two-year olds, Junior and FOUR KITS!  We’ve only had nine once before!

Wow, that bank hole must be crowded!

I guess during that early video from Moses one must have been still asleep? and missed out on the swimming lesson? I can’t wait to see four for myself and find out what this unexpected edition has in store!

I noticed that my letter to the editor was published in the Gazette. I was greatly annoyed by the loss of the fallen tree, when so many other nuisances are allowed to accumulate in the creek and this seemed like the best way to say it.

 The tale of the invisibility park

Once upon a time there was a town with a patch of green that stretched between the creek and corp yard where everything that occurred became magically invisible. No one knew why.

 At any hour of the day homeless, transients and criminals could drink alcohol, smoke weed, huff, sell drugs or even examine the contents of stolen property and even the police who visited would avert their eyes because the park, and everything that happened there, was invisible. Maintenance never disturbed the layers of trash, sleeping bags or empty bottles strewn there and the creek was allowed to become cluttered with debris.

 Meanwhile, 30 feet away, a still living tree that had leaned into the water, providing food and shelter for birds, fish and beavers, was swiftly removed at considerable city expense. Because unlike the other miles of creek littered with shopping carts and tires, this particular section was NOT invisible.

 – Heidi Perryman

Any time I can express public disapproval of the city’s ridiculous actions creatively enough to avoid looking mean, I’m a happy, happy girl.

Everything old is new again

The first time, ever I saw your face from Heidi Perryman on Vimeo.

Things are looking familiar down at the beaver dam. Three kits and at least four adults in residence, plus Junior. It all makes for some pretty exciting beaver viewing. Not to mention that apparently five out of the six new pairs of kit eyes are developing conjunctivitis just like the old days…Sheesh. Rickipedia pointed out that the e coli in Palo Alto streams all starts with grazing cattle in the upper watershed. And I bet that’s how our beavers got unlucky again. Another reason to dislike cows near open water. Funny that everyone assumes it’s the city life and chemicals that give our beavers a hard time, when its really the wide open spaces with cows.

Here the new kit is feeding alongside mom and dad. You can even see mom remind him of his manners. I particularly love how fully the kit is part of their lives. He goes where they go, does what they do. It makes me remember those rare moments as a child when I was allowed to tag along with my father to work. It was so exciting to be with him in his big world. Beavers always bring their kids to work. Every day, whether their mudding or damming or feeding. It’s part of the package.

Side by side from Heidi Perryman on Vimeo.

We’re still waiting for three kits to pose kindly in the same frame. But trust me, there are three. Apparently two share a similar gender or disposition and like to hang in pairs. But one is definitely his own beaver, and rejects the opportunities to crowd with his siblings. I think it’s the one with only one eye infected at the moment, so maybe that explains it. But since beavers groom their entire bodies and spread that bacteria around, I’m sure it will be both soon.

Let’s hope a high tide and some fresh salty water will help clean everyone soon. Mom’s been shaking her head a lot lately, so I’m guessing hers is an ear infection. Stupid cows.

With three kits and so many adults there’s always lots of time for my favorite thing. If your sound is up I think you’ll be able to hear a little of it here.

The ‘tooth’ hurts

‘Justin Beaver’ chips 2 front teeth after falling

BOULDER – A young beaver – creatively named Justin Beaver – is recovering from his injuries after taking a tumble off of Boulder Falls on June 19.

According to Greenwood Wildlife Rehabilitation Center, Justin – who is a little over a year old – broke his upper front tooth down to the gum line and chipped his lower front tooth. He also had to get multiple stitches to repair the laceration on his head. He was brought into the facility by Boulder Park Ranger Dave Gustafson.

Gustafson says he found Justin just above Boulder Falls on State Highway 119.

 ”I was driving on into work – happened to be on call that night – and saw him in a place that beavers don’t live,” Gustafson told 9NEWS. “He was trying to walk back up the canyon. There’s some beaver dams [near Nederland.]“

 Justin’s lower tooth will have to be shaved down to be at the same level as his other, undamaged lower tooth. If beaver teeth are misaligned, beavers cannot eat anymore and will die. His upper front tooth will have to be trimmed on occasion, but since they are still coming in, a more permanent solution won’t happen until the tooth is done growing.

Ow! Poor Justin. That’s a long fall. Good thing a rehabber was on hand to help, although I’m not sure how a beaver with shaved down teeth is a solution. Rodent teeth never stop growing. So that means he’s never going to be able to go back to the wild?

This article makes me think about our original mom beaver and her fatal broken tooth. I don’t think upper and lower incisors are supposed to ever meet but I guess the pair matching matters because she punctured her own palate which left her vulnerable to a host of infections. In the end she couldn’t even chew because her mouth hurt too much. I remember she let us nudge her easily into the carry crate. She rode in the back of my subaru to the Lindsay Wildlife hospital where they decided to euthanize because her injury was so severe.

It was five years ago almost to the day.


Honestly when I went down this morning I purposely decided not to bring a camera because I thought it would just be too sad, but I wish I had filmed it so you could all see how completely calm and unpanicked mom was. she just was in no condition to react, and if we had left her alone she was in such a visible part of the creek that people would have intervened and/or called animal control. This way she was completely protected by us and not at all agitated or frightened. It was almost like she knew we wouldn’t harm her, and it certainly felt right, after everything we have been through and all the mornings I have spent with mom to have her riding peacefully in my subaru. We will be out tonight to make sure the kits are feeding and happy. It was becoming clear that the family has already transitioned and the kits have been relying on the yearlings care more and more, which is just like we’d hope.

You would think after five years, a lovely new mom and 8 new kits, it wouldn’t make me cry anymore. Hmm.
