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

Month: August 2009


UPDATE:

Go here to find out what happened at the meeting.

The question of access to the beaver dam will be considered by the newly formed Parks, Recreation, Marina, and Cultural Commission Tuesday evening at 7:00 pm in City Hall (525 Henrietta St). This kinder, gentler civic body counts several beaver friends as members, so we are more likely to get an outcome that is good for both the beavers and the city than when the ominous but ineffective chain was hung across the path with a warning from the Police Department.

To be truthful, Worth A Dam is rather ambivalent about the access issue. On the one hand we want to keep visitors from approaching the beavers, climbing on the dam, or visiting the lodge. We don’t want homeless sleeping or drinking down there, and we don’t want pets to come sniffing either.  But on the other hand we can see the immediate softening of hearts that comes with standing on the bank and seeing beavers so close. Families and children and groups of all ages are mesmerized by the experience, and we all know we protect the things we care about. Our photographer could never have taken the pictures she has without access.  I didn’t actually use the bank to watch beavers until the sheetpile-palooza left me worried about their safety and wanting to closely check each one. Before that all of my videos were filmed from bridges or street side. That is until I felt I was worried about mom’s eye and wanted to see it regularly.

Ambivalence is a developmental accomplishment. Having mixed feelings is something you are incapable of doing when you are three or five or a member of the Bush administration. To be able to hold both sides of an issue in your heart, to see gray area, and to really feel two ways at once is the sign of a more mature mind trying to figure out the complexities of the world. Our mixed feelings about access center on the fact that we want the beavers to be safe, and we want people to have an opportunity to be moved by their closeness.

Separate from either of these goals is the need the city has to not be sued if someone falls in or breaks an ankle. We think that issue can be easily solved by signs saying “Enter at your own risk” or some such language to indicate that the city doesn’t maintain liability for the area. We have suggested “Sensitive habitat” signs warning people not to approach the wildlife, bring pets, or climb on beaver structures and Worth A Dam has offered to pay for these. We generally feel that any fencing built should be gated and that Worth A Dam members and docents should be able to provide access, so that if a docent is on sight you can come down if you wish. Certainly we feel that any fencing that prevents access from the dam should prevent access to the lodge as well. And finally that nothing built to block access should interfere with the habitat or the trees in any way.

It’s a tall order, and maybe a few supporters in the audience would help guide the process. Come by tomorrow if you can and support compassionate decision-making that will keep our beavers safe and valued for years to come.


No this isn’t the iris of a deeply attentive cyclops, its the graphic illustration of the relationship between species as illustrated by the Muir Web project envisioned by Eric Sanderson, an ecologist that works with the wildlife society at the Bronx zoo. He became interested in creating an accurate representation of what New York looked like 400 years ago, right down to the beavers and bogs, and this tool helped him understand the relationships.  His hard work produced “the Manhatta Project” which was exhibited at the Museum of the City of New York and is featured in this month’s National Geographic.

The article begins with a discussion of the mysterious arrival of Jose, remember him? He was the beaver outside the Bronx zoo that was named after congressman Jose Serrano who pushed through 15 million in federal funds to support the river’s cleanup. I wrote about his appearance last year when his positive effect on birdlife was noted in Audubon magazine.

The article goes on to describe the Manhatta Project in detail, of which the creation if the Muir Web tool was just one piece. The idea is to  better understand our ecological heritage and know what Henry Hudson saw when he first  looked at Manhattan.  The project has sponsored a flurry of attention, and the teaching curriculum is available online here. It even references our good buddy Bob Arnebeck.

Of course you’ve already guessed my favorite part of this article. Take a look at author Peter Miller’s description of a certain familiar landscape engineer.

Consider a beaver that lived at Times Square in 1609. If you grabbed him by the scruff of his neck and lifted him out of the web, you’d find lines connecting him to a slowly meandering stream, to the aspen trees he ate, and to the mud and twigs he used to build a lodge. Not only that, you’d also find lines to the bobcats, bears, and wolves that depended on him as prey and to the frogs, fish, and aquatic plants that lived in the pond he helped to create. “The beaver, it turns out, is a landscape architect, just like people,” Sanderson said. “You need him to flood the forest, which kills the trees that attract the woodpeckers that knock out cavities that wood ducks use for shelter.” Lifting a beaver out of the web disrupts scores of other residents, which demonstrates how important it can be to think about an ecosystem as a network.

Well gosh that’s nice to read in National Geographic, but frankly the city of Martinez figured that out all by itself! Go find your own copy because there’s a beaver graphic in there that will blow your mind!


So last night a pair of Berkeley beaver supporters took amtrak to our shores to cash in on their “private beaver tour” purchase at the silent auction. Worth A Dam was there to meet them, explain the habitat and introduce our beavers. They will be cycling over the new pedestrian portion of the Benicia Bridge when it opens. Phil is the thoughtful author of the Bay Area Bird Blog, and I met Juliet through her work with the Sierra Club back when the were drafting their position statement on the Martinez Beavers. She is also featured on our video letter to the mayor from last year’s beaver festival. The couple are avid environmentalists and have restored their Berkeley garden as a native plant oasis. They gave us a crash course in willow care while we toured the 3 and a half dams.

The beavers were very obliging last night and made a charming and intimate appearance, even giving them a stand-up view of their ambered bottom teeth. A pond turtle and a slider were seen at the lower dams. The banded green heron displayed boldly by fishing at the end of the pond leveler pipe, and a wiggling little muskrat made a dash on the dam before giving a longer display at the edge of the grass.

All in all the animals were in fine form last night, and the human visitors were all polite, curious and helpful. One of the things I loved at the start of the tour was someone stopping us to explain where to look for the beavers and their general habits. It was no one I recognized, just someone doing their part to introduce our famous residents!

Here’s hoping the ride across the bridge gives them great views! We know you have sharp eyes and won’t miss a single bird sighting on the way over!


This is what a hero looks like:

I don’t need to show you what a villain looks like: you’ve all seen the photo. Whatever you take from this horrific news story I hope you remember that the campus police at UC Berkeley can sniff out evil in 18 minutes that the city of Antioch has ignored for 18 years.


I’m sure that you all remember our badger friend, Susan Kirks, who has been working to save their habitat by protecting open space in Petaluma. She was at the beaver festival and made a slew of connections. The city of Petaluma is partnering with her organization Paula Lane Action Network (P.L.A.N.) and is negotiating a deal to purchase the land for a community wildlife corridor and educational center. There is just a little more fund raising to do to make it possible.

Carolyn Jones, the reporter from the Chronicle who has almost always been kind to us, met up with Susan and ran a nice story this week on the Petaluma Badgers. To my mind it has too many quotes along the lines of “beavers flood creeks” etc, and not enough about the good that they do, but still it got people’s attention and it was good press for her cause. Because of this I was able to send it along to our friends at Bay Nature, the Daily Planet, and the SF Bay Wildlife Info who can’t wait to follow up. It’s exactly the kind of story that gets written about because who thinks of badgers in Petaluma?

Susan writes excitedly about her week since the article came out:

So far — I came home Tuesday and there was an envelope in my little black mailbox from a woman who lives in Paradise, CA – with a handwritten letter and a check for $25 – thanking us for all we are doing to help to save the badgers. I do not know her and called yesterday to say thanks. Then, the Open Space District a call  (and referred her to us) from a woman who’s the Chair of the “North Bay Badgers,” the alumni group for Univ. of Wisconsin (“Bucky Badger” is their mascot) and she thinks the Bay Area Badgers might want to do something to help, very enthusiastically said maybe they could do a fundraiser to help us with the land acquisition costs – or something! And this morning there’s a message from our local paper, the Press Democrat, saying they heard about the story and [finally] want to do a story.

THANK YOU for being you and being where you are.  I had no idea a simple request for doing an article on badgers, to connect with beavers and other wildlife, might lead to this.  I’m hoping for all positives!  The City of Petaluma is abuzz.  People are being very nice to us!  S
