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

Month: January 2012


Pollock & Perryman at Primary Dam

Wow. Yesterday was a dazzling blur, and I’m still  trying to feel my way through it. We woke up early to pick Michael Pollock up at the train station, then drove to the meeting at Occidental where we found a room full of 20+ folks I had been emailing for the past year from various government and environmental agencies all ready to work hard, talk about beavers and change the way folks saw the role of beavers in watershed.

Some of them I knew, like Brock, Rick, Lisa and our Tahoe friends, but some were a delightful introduction to someone I had swapped email with but never met.  It was a positive, knowledgeable, cheerful, pragmatic and very intriguing group. Michael found out at the last minute that he lost travel funding so Worth A Dam made the decision to pay for him to come down. I figured that having him there would really make a difference and was worth the train ticket. Brock and Rick are kicking in too.

The meeting was well facilitated by the OAEC’s director Dave Henson, and started with introductions and background. Then Rick and I reviewed the historical distribution paper and talked about where beaver belonged. Pollock made the excellent point that he couldn’t think of another instance where government agencies were relying so heavily on a 70 year old paper, and we all talked about how to change the mindset of today.

Then he presented his data from the current work which is looking particularly at beavers and steelhead, having pretty handily answered any Coho questions. After which we were treated to a delicious lunch, mostly grown on site, and a tour of the gardens. I chatted with our Tahoe friends about their upcoming grant project to get funding for school presentations and their 501.3(c) application.

After lunch we talked about obstacles and made schemes for the work that needs to be done to get a beaver management plan at CDFG that recognized beaver’s incredible assets, acknowledged the damage done to habitat and wetlands by their removal, and required that certain steps be taken to try and solve the problem humanely before trapping. Then we went around the room and discussed  what we had taken from the day and what we were going to do next to advance our goals.

Somewhere in the day, Eli Asarian agreed to do the hydrology graph for our article, Lisa gave me a present of a lovely antique postcard from her grandmother, Rick gave me an adorable and entirely fitting ornament of a beaver curled up in a gift box,  and Pollock gave me a series of frames containing the historic 1930 article from Popular Science about beavers on Mars – along with the most whimsically charming beaver card I believe I will ever see that he bought in Montana. Here’s the Monte Dolack painting that it’s from.

Afterwards there was dinner, conversation, and wine before a stroll under  a brightly jeweled cold and clear starry sky that poured the Milky Way right onto our car.

Chuck James, the archeologist who found the remnant beaver dam all those years ago and kick started the historic paper with his efforts, followed us back to Vallejo before heading off to Redding), and we got home sleepy and dazzled from the day. After a chat by the fire and look at the giant beaver skull (which Pollock had always wanted to see) and the scrapbook of our first year’s beaver story, (which he was less eager to see but he just had to look at to ‘get’ Martinez story),  we brought him back to the train station where he embarked on another 22 hour journey home.

(My lost weekend was unbelievable, but his has to be  something out of Salvador Dali.)

Well 2012 might not be the “year of the beaver” but I am more hopeful than ever before that big things are moving and shifting on the beaver front. This is as good an opportunity as any to thank the literally thousand of helpers that have cared about our beavers, cared about beavers in general, or taught us valuable lessons along the way.

It is said that the journey of a 1000 miles begins with a single step but when I finally fell asleep last night it  felt more like we had just taken a series of sprinting leaps.

California Working Beaver Group Meeting at OAEC

So the director of public works assures me that they didn’t lower the pipe and that the pond will be the same height. Seeing that the filter is underwater I would be entirely uncomforted by this reassurance EXCEPT for that I had a profound realization at 3 am that changed my outlook entirely.

Bear with me here, but before they reinstalled the filter the pipe had been laying directly on the pond floor since the big washout in March. So all of spring and all of summer the pond was ‘controlled’ by a pipe placed at ground level. Although we saw Reed try and plug the pipe on the anniversary of mom’s death, it wasn’t until Dad came back in August that it stopped flowing.

Which means that even if they DID lower the pipe the pond won’t be any lower than last summer. Which is reassuring.

I went down this morning to check on the recovery expecting fierce rebuiding and maybe a red cross unit. I saw two beavers munching, a sleepy night heron, and no work done whatsoever. The tide was high so the secondary was mostly covered but you could still see the gash and nothing had been done to restore it. They clearly have their own pace at these things, even when we humans panic. Alright. We’ll sit tight.

Martinez has no monopoly here. Lots of stupid beaver news  around the country and beyond this morning. Remember Upton, MA the city with the rare dragonfly that wanted to kill its beavers without ruining it’s special bugbog? Well they paid Mike Callahan to install a pipe to lower the pond, paid for the  conservation commission former trapper to renew his license and kill two beavers and now are reporting that the pipe will keep the other beavers  away. (Like Garlic?) Given the fact that I wrote the conservancy and the paper many many times that this was untrue, and the fact that they wrote me back so you know they read it,  we will have to attribute this pretend conviction to willful ignorance and let Upton go with love.

Michael Callahan, of Beaver Solutions in Southampton, installed a pond-leveler which pumps water out of the bog while keeping beavers away.

A second bit of stupid comes from Scotland where there’s been rumors that they might just let the free beavers on the Tay stick around and do their thing. Paul Ramsay and friends did such a good job slowing down the massive beaver trapping that they might have escaped with only the zoo-death of Erica to show for it.  Apparently the Scottish Game Keepers association is very alarmed at that idea and is ‘gamely’ offering to help do away with them.

One farmer in Angus is having to fell beaver lodges weekly on an adjacent burn to prevent large-scale flooding, with the animals regularly raising the water level by over a foot. “If I wasn’t having flood problems, I would be happy for the beavers to stay, but I don’t honestly see how we can carry on with it,” he said. “They have caused significant damage.”

Finally, a BEAVER-TRAPPING LOTTERY IN OHIO. (No I’m not kidding) Apparently they have so many compassionate humans that offer to protect their streams from beavers that they have to hold a lottery to decide who should be lucky enough to get to do it. Unbelievable. I have never felt closer to the Buckeye state than I do at this moment.

The city of Mansfield will hold a lottery card drawing for controlled beaver trapping at Clear Fork Reservoir. Two units will be available, a north unit and a south unit. Each successful trapper may have one assistant. Interested trappers may apply by mailing a 4 x 6 inch post card to Gary Foster, at 2678 Gass Road in Mansfield, 44904.

On a final note the website has been acting up lately and you probably encountered trouble loading pages. I’m told that it’s likely a ‘cache’ problem and have temporarily shuffled the home page down to holding only the last three posts to adjust for it. I spoke to our good old friend Scott Artis yesterday who is off bravely embarking on a new career in Bakersfield and he kindly said he’d look at it this weekend. Thanks Scott and let’s all keep our fingers crossed.

Too much information on this site. Apparently I talk to much. Who knew?

Moses Silva dropped this off this morning. Enjoy!


Lory called this afternoon saying the the dam had been lowered. We realized eventually that the missing filter had been replaced (which is necessary) but couldn’t understand why there was so much fresh mud on the dam. Then Jon realized that the city had ‘dug down’ the filter before securing it and tamped the mud and sticks back onto the dam. If the intake of the pipe is much lower, it means the pond can never return to its previous level, and runs the risk that there won’t be enough water for the beavers and they will simply start a new dam upstream.

Since April we have talked to public works about the need to restore the filter. We were advised by beaver management experts that it was problematic to let the beavers “learn” or have practice plugging the pipe. Worth A Dam suggested having Skip come out this January and restore the filter, but was assured that Skip had taught public works everything necessary to do the work themselves.

Unfortunately, looking at the effects of their January 13 efforts they appear to have lowered the filter height by ‘digging out’ the pond floor putting the mud on on the dam, presumably to keep the water level low. This means that no matter how hard they work the beavers can never get back their pond. And may not tolerate the change.

Skip was very clear that lowering the water level increased the risk that the beavers wouldn’t adapt to change and would instead simply rebuild another dam elsewhere upstream where they could have a better pond. Looking at the sunk filter it is hard to imagine that the pipe isn’t 6 inches lower or more, meaning the water height could never restabilize to last years level. Hopefully our flexible beavers will tolerate the abrupt change, but Worth A Dam will continue to monitor the situation.

Oh and for good measure they also ruined the secondary dam. Grr. Lets hope the beavers have more patience than I do!
