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

Category: History


UPDATE: Baby otter seen at 9:30 above the primary dam this morning! Same size as the 8 Jon saw yesterday! Mom is getting breakfast and he’s fending for himself! Keep your eye out for visitors.

Sometimes a glimpse of the past is shocking in its ignorance. I have a book from the 1700’s on how to raise a good  wife, for example, that says girls shouldn’t be praised for being clever or competent. (Just had to buy that one.) Other times we can only wonder why yesterday’s wisdom took so long to catch on. This is an issue of Life Magazine from Nov 1943 extolling the contribution beaver make to our soil by preventing erosion and raising the watertable.. 68 years ago the major publications in the country were talking about the value of beaver to the watershed and discussing their reintroduction to arid western regions. Why do attitudes about beavers have such a slow learning curve? It’s important to note that Donald Tappe had just finished his seminal paper on historic prevalence of beaver in California. I’m sure he would have followed up with a second that corrected some of his mistakes about beavers-only-living-above-1000-feet but he was drafted that year and never got around to it.

Well, don’t feel bad. Martinez is way ahead of the curve on this one. I received an email this morning from a downtown merchant who had just read about the Placer County Beavers being killed in the Tahoe Wildlife Care Newsletter and wanted to let us know that we should help! Mind you this is a merchant who at one time had been so afraid of beavers flooding the city they were committed to avoiding that eventuality through any means necessary. Now Skip’s battered Castor Master, (and our cooperative beavers0 have eliminated those fears and we find friends in unexpected places. It’s been quite a ride, but I thought you want to see what America was thinking about beavers in 1943.


Even though the beaver research group that formed last march has (temporarily?) disbanded, our chief historian has been soldiering bravely onward, pouring through volumes and looking for evidence of beaver in the sierras prior to the 1900’s. His Wikipedia beaver-in-Tahoe page has grown to stunning proportions. He introduced his thesis at the Santa Clara creeks conference to rave reviews, and then submitted it as an abstract for a paper which was accepted for presentation at the salmonid restoration conference in March. Recently, he has been working to persuade some Tahoe scientists to see the light since the rumor that beaver aren’t native is making the rounds again for the current batch of beaver killing in Truckee.

The other day he pointed my attention to this from the Tahoe Science Institute:

Summer 2009 (clarification of one point of this article is required – beaver were native to the Sierra Nevada, apparently got trapped out by the early 1800s, and then were reintroduced in the 1930s and 1940s. While we don’t usually point people to Wikipedia for their research, there is a fairly exhaustive treatise on the matter, with references, HERE)


Chipping away at beaver mythology, one branch at a time! Thanks Rick, we’re grateful for your patient persistence. I mention this because last night he sent out the final edits of archeologist Chuck James paper on beaver prevalence which will eventually be submitted for publication. Let’s hope we can convince a few journals to be interested. As Rick is fond of noting, A long habit of not thinking a thing wrong, gives it a superficial appearance of being right, and raises at first a formidable outcry in defense of custom.” (Thomas Paine) It’s important for people to stop using lies about nativity as an excuse for killing beavers. Not that they won’t find plenty of others, but its a start.


Other good news to start the work week? Our own Cheryl Reynolds gave me a lovely beaver tote for Christmas that was so adorable I had to track down the makers. I wrote BlueQ just last night to see if they’d considering making a donation for the festival. You never know what will happen when you ask. I heard back from them today that they were pretty much persuaded by the secret-weapon photo I sent. Fingers crossed, expect the best ever goody-bag at this year’s beaver festival!



This Christmas Eve the Daily Iberian in Louisiana published another head-scratching WTF article. In it we learn that in addition to being considered a ‘nuisance animal’ by the State Department of Wildlife and Fisheries, beavers are ‘not native‘ to the region and have ‘no natural predators’!

Big, bad beavers are wreaking havoc on drainage channels in Iberia Parish, said Public Works Director Kevin Hagerich.  Not indigenous to the area, beavers have started appearing here in the past several years, Hagerich said.  “It seems to be getting worse every spring,” said Public Works Supervisor Herman Broussard. “They don’t have too many natural predators down here.”

Lets take those points one at a time, shall we? Beavers aren’t native in Louisiana? Umm…what do you think all those French people were doing there in the 1700’s? and 1800’s? They came down from Quebec looking for something. I wonder what it might have been?

The French in Canada, relying less and less on Indians to serve as middlemen, spread rapidly into the interior of the country, where fur-bearing animals were plentiful. Father Jacques Marquette and Louis Joliet, a fur trader, reached the Mississippi River in 1673. The Sieur de La Salle followed them a few years later, in 1682 reaching the mouth of the river and claiming the entire Mississippi Valley for France. La Salle planned to found a colony in Louisiana, as he had named the region, to control river traffic and keep a monopoly for France on the fur trade there. His plans were carried out after his death, and New Orleans was founded in 1718, cutting off the British from use of the Lower Mississippi. Fur Trade

So the French came down the middle and the English came down the coast across and the Dutch came across the Hudson and Louisiana itself wouldn’t have been worth fighting over if it wasn’t for beavers. It was a big greedy free-for-all where destruction of several native peoples was just an incidental bonus in the pursuit of wealth. I’m going to go out on a limb here, boys and say if the entire economy of New Orleans was based on the beaver fur-felt hat industry circa 1750 then we can assume that beavers were native to the area.

Let’s move on to the pesky predator issue. Last time I checked the state still had a whole mess of these:

Turns out they live the same place beavers do! They have a pair of the most powerful jaws on the continent! And they eat meat! They can even hold their breath a whole lot longer than a beaver, which has zero defenses against them!    Whew, that must be a relief.

Now as for beavers being a ‘nuisance species’, I really can’t argue with that. They can create a ‘nuisance’. Small, narrow minds focused on short term solutions can find them an awful nuisance.  They build dams and chew trees and generally change things. I bet a smart parish like Iberia, however, could be smarter than an actual beaver. You could install flow devices, protect culverts and wrap trees. Then your ‘nuisance species’ could improve your water quality, increase your fish populations, raise bird count and provide essential wetlands for wildlife and a much needed buffer for your coastline. It would be like an investment. Sometimes a ‘nuisance’ pays off.

Just one more thing. Since you seem kinda confused about history, you do know what your state was named after right?



It’s the time of year where beavers are in a ‘tailspin’ rushing about to take the last few trees into their underwater larder before the freeze. It’s also the start of trapping season in most areas, historically because their coats get big and fluffy for the snows making the pelts more valuable. There have been, literally, five stories each week describing how trapping is necessary in North Carolina or Manitoba to control the population, and more stories than I can stomach about offering a bounty for tails — even raising the price on the bounty to make it more attractive.

Now the entire country of Scotland has gone beaver-stupid on a national scale and I am stunned to read the ridiculous, fisherman-fueled, robustly unscientific trifle coming out of that country daily. Never mind that countless studies have proven that beaver dams are not only no obstacle for fish but provide essential pools for juvenile salmonid. Don’t bother me with the facts, I have my mind made up. There are even those who ignore the historical writings and skeletal remains and insist that there were probably never beaver in Scotland to begin with!

Scared people get stupid about lots of things, but I have come to believe beaver-stupidity is unique in its contagiously panicked overlook of  data.

Well, let’s leave the trenches and admire the view for a morning, shall we? I was listening to a lecture last night called “Effecting Change: Advancing Global Health” with advocates from the Gates foundation talking about applying  the tools of marketing to get the world to focus on solvable health problems and solutions. They felt that the real role of the advocate was to tell stories, and to tell them in such a way that other people felt inspired to help. This meant they couldn’t be too depressing or overwhelming, because then people stop listening. They had to introduce a personal view (rather than a large scale view) and show a problem that got solved.

Of course, I couldn’t help but listen with my own experience  thinking about our role with the beavers. Obviously we’re talking about a much smaller, local, furry scale, but its still the same basic principal of encouraging people to get involved and to feel like they can do things that matter and effect change. Personal connection, check. Accessible story, check. Real solutions, check.  Public opinion can tolerate bad news, such as the first kit’s or mom’s death, but not too much bad news, such as the wholly atrocious half million dollar ponzi scheme to install the second layer of sheetpile. There has to always show a light at the end of the tunnel and a clear path  how to get there, even when we aren’t sure of the way ourselves.

There are parts of the argument I don’t like. Morally, I don’t want advocacy to be the same as marketing, and I don’t think that marketing always does such a great job anyway. (Look at the Chevy Nova sales in Mexico, for instance!) I want people to do the right thing because its the right thing, not because its convincing. Still,  mostly I’m a pragmatist, and I just want them to do it. Clearly there are parts worth gleaning of this argument, reminding me to keep telling good news, or good stories inside bad news, and to always focus on solutions.

In that vein, I offer this cheerful beaver observation by veterinarian and naturalist Nelson Poirier from New Brunswick, Canada. It appeared in the TimesTranscript this weekend with the auspicious headline: Our symbolic beaver overcome challenges of the past. He took the time to document the historic value of beavers and had some pretty remarkable things to write about their role in the economy.

One may ask why this mammal has become such a significant Canadian icon, right up there with the maple leaf and common loon. All three of these icons find New Brunswick a very pleasant place to call home. Although the beaver is widely distributed throughout North America, it is very much at home here in this province and although its waterway reconstruction and dam building can occasionally create confrontation with man, for the most part it lives in harmony with us and compliments our landscape creating complete wildlife communities with its construction efforts. The beaver was the first land natural resource to be exploited in Canada and that started mainly right here in the Maritimes. The beaver pelt had always been held in high esteem by native Canadians. When Europeans arrived, however, the beaver pelt quickly became the unit of currency in the new land. Native wars and feuds were fought over rights to trapping territories as fortunes were made and lost in the fur trade.

I thought this part was pretty stunning, and it reminded me of our parallel story in California.

“The first mention of the placing of restrictions on trapping is in 1877 when the season for mink, otter, fisher, sable (marten), and beaver was set as Sept. 1 to May 1. A closed season was declared for beaver in 1897 which was continued to the present day (as being written in 1945). Permits were issued for limited trapping for a few years but this being very difficult to control, stopped in 1919. It was also found very difficult to prevent poaching, and the beaver continue to be scarce. In 1933, the game wardens estimated the total population to be 162 animals in 38 colonies. Although there were probably some colonies they had not heard of, this indicates how scarce beaver had become. During the last 12 years it has become increasingly difficult to take and dispose of beaver skins illegally and the steady increase has been reported. In 1944 in 1945, the beaver population being estimated as nearly 20,000, limited trapping was again permitted. It is interesting to note that Denys (1672) and LeClerq (1691) both called the beaver, otter, and muskrat, four-legged fish, and said they can be eaten in Lent. Even Cooney (1832) said that the beaver was considered to be the connecting link between the quadrupeds and the fish.

Of course I wrote Mr. Poirier and sent this article off to our historian friend, who has already added these papers to wikipedia. Nelson wrote back that he likes beavers a lot but they make very uncooperative veterinary patients, and “don’t even think about leg splinting them!” which made me smile. What’s stunning to me is that in 1832 a man noticed that beaver was the connecting link between quadupeds and fish and the entire country of Scotland hasn’t yet got the memo.

It’s a nice beaver article, (and yes we’re grading on a curve). Go read the whole thing and sigh wistfully that we’ll never get to see steam rising out of the vent hole for our snow-bound beaver lodge! (Although I’m sure they don’t mind at all!)  Tomorrow Worth A Dam will meet 60 third graders at the  dam to spread a little beaver education and gospel. Hopefully we’ll leave clues of our whereabouts so check out the sidewalks later! Wish us luck.



So beaver-friend Brock Dolman gathered with some Nevada-city beaver friends in preparation for this weekend’s indigenous people celebration “calling back the salmon‘ event. There he had the fortune of meeting Farrell Cunningham, one of the only living speakers of the Tsi-Akim Maidu language. Guess what they talked about?

“I asked him his Maidu opinion about pre-contact occurrence of beaver in their territory and he said that they have a word for beaver: Hi-chi-hi-nem and that it is a pre-contact original word vs. a post-contact newer word and thus he was confident that they were familiar with beaver in their territory, the majority of which is well above the 1000’ elevation on the West slope of the Sierras.”

Certainly good news for the continuing struggle to prove that beaver were native in california at higher elevations too. We will keep gathering stories.In the meantime you might enjoy this video of Farrell keeping the language alive through teaching.

A final note to regular readers of this blog is that our good friend Scott Artis of burrowing owl fame is going to be taking on the job of upgrading this site. What it means is that the look of the site will change while we get situated, especially the sidebars which will need to be disabled and updated. Don’t panic, www.martinezbeavers.org/wordpress will be back and better than ever very soon. Fingers crossed and thank you, Scott!
