Back down the mountainside after a dynamic presentation, good conversations with enthusiastic rangers followed by a cheerful lunch and drive swapping stories. This is an excellent picture of my traveling companions. I would be disappointed that the one of me didn’t take, but I have this slide as a token of my treasured adventure,  which is much, much better. Look closely, this was presented by Dr. Pollock and summarizes research he did comparing the benefit to smolt production (baby salmonids) from  large woody debris (LWD) placed in a stream bed versus the benefit of a beaver dam in a stream bed.

.

Take a moment to truly let these numbers sink in. We go from a benefit of tens of fish to more than a thousand fish.  Not to mention that ‘replanting’ woody debris in ponds is expensive and time consuming. Beavers do it for free and do it vastly better. A powerful sermon in the growing beaver gospel!

When I got home there was an email from Glynnis Hood pointing me to this radio program. It’s a lovely interview and describes her excellent research and upcoming book.  Go here to listen. I’m off to sleep for a couple hundred years. Wake me when we have new kits.


From the WTF files comes this very misleading article about tribal efforts to keep beaver dams from blocking salmon on the Skagit River in Western Washington. It’s a pretty remarkable obfuscation because by the second sentence in the article it pretty much erases years of research by Michael Pollock, (who works all of 70 miles away) and mislabels what a “beaver deceiver” actually is even though Snohomish County (which is the first place I learned about a beaver deceiver) is only 50 miles away . I have sent it to our salmon friends for their review and I’ll tell you what they say. The shocking part to me is that the tribe is actually working with NOAA who is paying Pollock’s salary to research and refute these bogus beliefs. I guess its like betting on both sides in a basketball game.

I suppose the believable part of the article is that beaver dams in culverts block salmon passage. It is true that there’s not much room to jump inside a culvert. (You might have clarified that, but I’m sure the salmon fishermen in Scotland are thrilled that you didn’t bother.) I guess you could get rid of all the culverts and the roads? Hmm, not likely.  Still, the tribe working to plant unpopular trees to keep the evil beavers away is stunning. Read this. And this. And then read this to find out what a real ‘beaver deceiver’ actually is.

Sigh.

Full lunar eclipse tonight which ends with the start of winter solstice. Google tells me those events haven’t happened together since the year 1638. Because of all the recent volcanic activity, it’s predicted to be very red in color. Apparently the west coast of America is supposed to be the best vantage point, so the beavers are lucky. If you’d like a reminder that we still live on a planet, look up at 11:41pm PST. The whole eclipse  will last about three hours.

What the Little Girl Said

The Moon’s the North Wind’s cooky.
He bites it, day by day,
Until there’s but a rim of scraps
That crumble all away.
The South Wind is a baker.
He kneads clouds in his den,
And bakes a crisp new moon _that… greedy
North… Wind… eats… again!_


There’s been a weird flurry of activity on the ‘beaver-saving front’. I had an email from one of the women who attended the Santa Clara Creeks Conference asking if it was okay to pass my name along as possible speaker for a parks conference. Sure, I said, thinking ‘regional parks’. Yesterday, I was invited to speak at the California State Parks Conference in Yosemite.  State Parks. Did I want one hour or two?

(Gulp. Just two?)

After I twittered about the house in a panic I wrote Michael Pollock and said, hmm might the NOAA ever authorize you to talk about beavers and salmon in Yosemite? He answered “sign me UP and lets call Rick”. So I talked to our historian-wikipedian friend, Rick and he can’t wait. We will be a “Beavers: How, Why and Where” triumverate  on the Ides of March in snowy-bound-early-spring Yosemite, convincing rangers to use different tools and let beavers stay.

Somebody pinch me.

Of course our state parks are in dire times here in California, or they wouldn’t have a conference full of riff-raff like me. But we will make sure the  state’s loss is the beavers gain. Deep breath. Hail Castor Yosemite!

More good news? I learned that our friend Adrian from Fur-bearer defenders (who just built the flow device) will be coming to the State of the Beaver Conference. And I just heard this morning that Paul Ramsay of Save the Free Tay Beavers will be there as well! It’s a long way from Scotland to Oregon, but he was lured by the keynote speaker, Donald Hey, and I don’t blame him. It will be a rare delight to sit in a room full of people who all know way more about beavers than me.


One of the signature characteristics of a Charles Dickens novel, (beside the rich characters, accessible dialogue, and fearless portrayal of class), is the number of coincidences that occur over the course of any story. He is famous for reintroducing the lost child to the searching mother; reconnecting young lovers severed through circumstance at a wealthy dinner party, (with one as a guest and one in service) and so on.  While some have speculated that his use of coincidence was a plot convenience, or a lazy way to wrap things up, it more reflected his belief in the world. His friend John Forester said;

On the coincidences, resemblances, and surprises of life, Dickens liked especially to dwell, and few things moved his fancy so pleasantly. The world, he would say, was so much smaller than we thought; we were all so connected by fate without knowing it; people supposed to be far apart were so constantly elbowing each other; and to-morrow bore so close a resemblance to nothing half so much as yesterday.

I offer this by way of introduction to the surprising connections beaver supporters have made. For those following along at home, let’s review; last summer we held our largest and most successful beaver festival. it was attended by the coordinator of the girl scout extravaganza for northern california, and she invited Worth A Dam to participate. At the Flyway Fiesta we offered a charm bracelet activity that was enormously popular, and that lead to Worth A Dam being invited to two-day Flyway Festival.

At the Flyway festival we met the hydrologist from USFS who introduced us to the archeologist from the Bureau of Indian Affairs who had carbon-dated a paleo beaver dam at 750 years old. The dam was in Red Clover creek, at 5400 feet in plumas county. He had wanted to publish a paper challenging Tappe’s assertion that there “were no beaver in caiformia over 1000 feet” but he wanted a co-author.

Meanwhile my work with the beavers had lead to an invitation to be on the board for the john Muir Association. I’m in charge of entertainment for earthday this year and needed to secure a keynote speaker. Our wikipedia historian friend (who found us through the website) suggested Brock Dolman, so i tracked him down and we started a conversation. His very broad connections include a group of what I will call ‘beaver-curious’ folk  who across the state who are interested in the restorative effect they have on the watershed. Brock was especially interested in the beaver-salmon connections and was able to convince the salmon conference people to add Michael Pollock to their line up this March.

Are you still with me? So Pollock gives his talk to a packed group who are very, very interested and he meets up with this Plumas county biologist from DFG who has a remarkable story to tell. Turns out he was the protege of the F&G old timer who was responsible for putting beavers in the the shasta region in the 1930’s. He of course, having read Tappe many times, thinks he was introducing them, and of course they thrived and did wonders for the watershed just as he expected they would. Touchingly, he said it was the ‘best thing he ever did’.

So the protege spent time looking at the hydrology and the terrain and began to get the sneaking suspicion that beaver had been there before; a reintroduction, not an introduction, but he didn’t want to argue with his mentor so he kept his suspicious to himself. Then he attends Pollock’s talk and afterwards an informal lunch discussion and learns about the archeologist and the carbon-dating and he announces that one of the creeks his old mentor had placed beavers was:

Red Clover Creek. The very place where the carbondated structure had been found!

Not enough coincidences for you? How about this little added tidbit. Way back when Martinez was talking about relocating our beavers to live on a reservation, guess where that offered asylum land was?

Plumas county.


Beaver friend, Brock Dolman of the OAEC (and featured speaker at John Muir Birthday Earth day!) rushed back from Redding to breathlessly describe the electric salmonid restoration conference he helped host which featured some surprisingly familiar faces. A shining star of the event was our new pal Michael Pollock talking about–you guessed it–the relationship between beavers and salmon. I don’t exactly have Brock’s permission to share the email but he didn’t exactly say not to either and I can’t be expected to keep news like this to myself. It’s THAT good!!!

Just back from an amazingly successful Salmonid Restoration Conference, where I moderated a 1/2 day session titled “Instream Flows for Salmonids” which had Michael Pollock as the final speaker. Over 200+ people packed into the room and filled every available space to hear his talk. There had been a lot of buzz being generated leading up to the session about beavers, and so lots of folks came to see & hear!! We then had an impromptu casual lunch time discussion that was open to everyone and over 60+ folks came to that as well!! All across the board there is a feeling of a swelling moment to bring beavers to the forefront of restoration!!!

Wow, think about what that means. There are watershed organizations across California worried about the salmon population. If a third of those tireless advocates became beaver believers we would be sitting on a beaver-boom town!  There really could be beavers in Sonoma and Marin and Los Angelos. We really could see a day when a city or property owner has to pay a “salmon tax” to get a permit to exterminate beavers! My fondest dream is that it becomes more cost effective to live with beavers than to kill them, and the funds for that “tax” go to a public account from which cities and property owners can take out loans to help pay for the installation of flow devices and culvert blockers. Ahhh a girl can dream. You can bet Worth A Dam will be happy to play a part in the process.
