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

Tag: Heidi Perryman


I am hard at work on the newsletter for our tenth anniversary, and I spent most of yesterday writing the origin story of Worth A Dam. As nothing else seems to be happening in the beaver world at the moment, I thought you might enjoy it.

origin-storyIt was certainly unusual to have beavers in the middle of town, as our city suddenly did in 2007. Maybe if nothing else had happened that’s all it would have been; a passing interest that eventually –  passed.  But when the city announced that flat-tailed residents would have to be eliminated people started talking: to their neighbors, to each other, to their representatives, and to the media.

Eventually the city was forced to hold a meeting to discuss the beavers’ fate. There were too many people interested to fit into city hall and the forum was moved to the High School Auditorium. Some 200 people showed up – coming from uptown, downtown, and out-of-town. There were representatives from the Sierra Club, the Human Society, local news and a documentary filmmaker. The vast majority overwhelmingly demanded that the city solve the flooding risk without harming the beavers.

Faced with such vocal public support, the city council agreed to form a subcommittee to study the issue further. I was thrilled to be invited aboard the task force which consisted of council members, creek professionals, beaver supporters and concerned property owners. We had 90 days to address the pros and cons of possibly living with beavers in an urban stream. We quickly recommended hiring Skip Lisle to install a flow device that would prevent possible flooding.

The success of that first big meeting originally left me with euphoric hopes for a positive outcome. I was surprised to learn that even after we succeeded in persuading the city to hire Skip and even though his device worked entirely as promised, there was still uncertainty about the beavers fate. Addressing the real (and imagined) concerns in the subcommittee soon made me realize that the fight was a long way from over. It was Skip Lisle who initially suggested that a nonprofit might be necessary to advocate for the beavers and direct funding over time. After watching the acrimony of those meetings even after flooding was averted with his help, I could see he was right.

In choosing a name for the organization  I remember thinking that the struggle was too bitter for something benign like “Friends of Martinez Beavers” or “Wildlife Protectors”. It seemed the name needed to be something snappy with a little feisty backbone to get us thru the long struggle that lie ahead.

Thus “Worth A Dam” was born.

And the rest, as they say, is history.


Salmon win court ruling that ‘sets aside’ Marin countywide plan

In a sharply critical decision that leaves Marin’s planning document in legal limbo, an appellate court ordered more analysis of how development affects San Geronimo Valley’s endangered coho salmon.

 The ruling by the 1st District Court of Appeal in San Francisco reversed a Marin Superior Court decision, “sets aside” the 2007 countywide plan and its environmental report pending study of the impact of creekside building on salmon, and declared that a building ban was improperly imposed in San Geronimo.

Did you read about the Marin appellate decision protecting salmon? Our friends at SPAWN took the powers that be to court with the backing of some 22 conservation organizations and won a decision that is making no friends among the developers. Capture1

Fishery activists at the Salmon Protection and Watershed Network of Forest Knolls, which contested county compliance with state environmental law and sued to get tougher creekside building rules, hailed the ruling as a triumph. “We hope that after this decision, county supervisors are ready to work together so we can save these species from extinction,” said Todd Steiner, head of the salmon network.

 “The judges agreed with Spawn that the county acted unlawfully because the environmental impact report provides no help to decision-makers or the public to understand the likely consequences of allowable build out,” said Deborah Sivas of Stanford Law School’s Environmental Clinic, which represented the salmon network along with attorney Michael Graf.

If that name sounds vaguely familiar, it should. Michael Graf was the attorney who represented Worth A Dam in the failed effort to stop the sheet pile from going through the beaver lodge. Remember? He generously charged us very little and got his friend the geomorphologist to walk our creek and do the same. The city didn’t mind breaking the law anyway, but that’s blood under the bridge now. Seems like eons ago that I was worried the sheet pile would kill the beavers or drive them away. Congratulations Michael and SPAWN for a fight well won!

All this lays the foundation for the NEXT lawsuit to appear in Marin. One where trapping ‘nuisance’ beavers is considered a threat to the  salmon population. What’s that you say, beavers weren’t native to Marin? (Or Alameda? Or San Jose?) Guess what was published and went online yesterday?

CaptureHere’s the abstract, but you really need to go read the whole thing. Eli’s graphs are stunning.

The North American beaver (Castor canadensis ) has not been considered native to the watersheds of coastal California or the San Francisco Bay Area. These assertions form the basis of current wildlife management policies regarding that aquatic mammal, and they date to the first half of the 20th century. This review challenges those long-held assumptions based on verifiable (physical) and documented (reliable observational) records. Novel findings are facilitated by recently digitized information largely inaccessible prior to the 21st century. Understanding that beaver are native to California’s coastal watersheds is important, as their role in groundwater recharge, repair of stream channel incision, and restoration of wetlands may be critically important to the conservation of threatened salmonids, as well as endangered amphibians and riparian-dependent birds,

The timing on this could NOT be better, as we head off to the Salmonid Restoration Conference this week. It ends with a piercing reminder of how important beavers are to salmon, which I’m hoping the timing of the Marin decision bumps into the news cycle. There are a lot of parts I love about this paper, and Rick’s son did a stunning job of pulling the whole thing together, but you’ll pardon me if this is my very favorite part:

Today California’s coastal beaver are widely regarded as the non-native survivors of twentieth century translocations, and when they cause flooding problems or fell trees, depredation permits are often provided. Understanding beaver as native to coastal ecosystems may impact this decision-making.

Of course, I would have phrased less subtly, like STOP PRETENDING YOU’RE KILLING BEAVERS BECAUSE THEY AREN’T NATIVE, IDIOTS, but this paper and the sierra ones should permanently bury the myths about beaver absence from most of California.

49 other states never believed it anyway. I’m glad we finally tackled the 50th.Figure 4 Lanman et al 2013_corrected_crop

So sometimes I open my eyes and email and I have no idea what beaver misfortune I will be writing about that day. And sometimes my inbox has a present all shiny with a red bow on top just for me. This morning it was a ‘good job’ email from John Hadidian, the senior scientist at the Humane Society, who had just read through his new issue of Human-Wildlife Interaction and seen my commentary. Gallant man that he is, he offered to scan it for me since it will be a while before its published online. Now it is followed by the  two page whining rebuttal of the researchers I challenged but we’ll talk about that later. Today let’s just enjoy ourselves, shall we?

commentary 1Consider this entire article a warning shot across the beaver-trapping bow and a irresistible recommendation for humane beaver management everywhere! (10 year old data, sheesh!) Honestly, what I personally am proudest of about this article is that it actually uses my education instead of dragging it shamefully along behind like the tin cans tied to a ‘just graduated’ car.

commentary 2Non-respondent bias? Oh snap! I never thought I’d be able to use those words again after graduate school. Now I want to say it all the time! And thank the hard work research and design stats teacher who got the concept through my thick head.  I actually hated hated hated math, and (shh) never did the homework. But I loved statistics and calculated every single formula by hand. Don’t ask me why. It made perfect sense to my way of thinking, where as many people (including my brilliant husband) loved math and failed miserably at statistics. Go figure. I know by now you’re probably thinking ‘doesn’t this woman EVER talk about anything besides herself? So this is the part about you.

comentary 3Yes, the heroic actions of town-ful of adults and children is what forced Martinez back to the drawing table and allowed Skip Lisle to be hired in the first place. When the people lead, the leaders will follow. (Except Janet Kennedy of course, but she’s gone.) There were so many young people who grew  up with this story. I just got a call this weekend from a freshman at UCSC who was a middle schooler when the story started and wanted to write a paper on how the Martinez beavers improved our creek.

commentary  4Cue the rousing anthem and the unfurling flag in the background! I just got goosebumps! Let me say that I truly believe only a hybrid psychologist-beaver advocate could have written this entire article in four tight paragraphs. I know I mostly coast along with insulting the hygiene and IQ of folks who kill beavers much of the time, but I’m really proud of this. Let’s all remember:

 
I pledge allegiance to the streams,
and the beaver ponds of America.
And to the renewal for which they stand
One river, underground, irreplaceable,
With habitat and wetlands for all.

 



Several aspen trees were felled by beaver along the Blue River in Warriors Mark recently. Special to the Daily

Am I the only one that gets a kind of tingly feeling when a paper runs a photo like this? Colorado Summit Daily has a fairly nice glimpse this morning of beavers-getting-ready-for-winter.

Beavers are active this time of the year!

My friend Terese Keil, property manager for Trappers Villas, called me the other day to tell me a bunch of landscaping aspen had been chewed down literally overnight by beavers.

A call to Fish and Wildlife confirmed several reports of beaver activity in Summit County and loss of trees on properties. Apparently, they are busy building dams and lodges in preparation for winter. The advice was to protect the trees with wire mesh along the bottom of the trunks.

Beavers are prolific engineers and builders, and prefer to work mostly at night; their specially adapted incisor teeth and powerful lower jaw muscles allow them to chew down trees. Their teeth never stop growing, and their four front teeth are self-sharpening. They have been seen to work as a team to carry a large piece of timber.

The author Joanne Stolen is a retired microbiology professor from Rutgers – now turned artist and living in Breckenridge, CO. This is a mere 2.5 hour drive from Sherri Tippie so I’m going to imagine that if they aren’t friends already they soon will be. In the mean time I have been perusing the linocuts on her art website and noticing there wasn’t a beaver yet. I’m guessing she’ll be inspired to fix that oversight very soon!

There are typically two dens or rooms within a beaver lodge, one for drying off after exiting the water, and the second, a drier, inner chamber is where the beaver family actually lives. Special to the Daily

And remember this Wednesday I will be talking at the Rossmoor Nature Association about our beavers and their effect on our creek. You know you have friends there, so see if you can get an invitation. I’d love to see some familiar faces.

Oh and if you need provoking after a weekend that was just too relaxing go read this morning’s whimper from Mississippi where they are bemoaning the fact that the federal governement (which they mostly don’t believe in) is now only going to pay for half the cost of killing beavers with the USDA and isn’t that a shame? I mean its not like the state needs the water or the wooducks or the trout or the filtration. Obviously those beavers have to be killed because flow devices never work and Uncle Sam needs to do it!

Remind me why I pay taxes again.


Beaver concerns boil over in London at city hall meeting

By Angela Mullins Metro London

Call it a battle for the beavers.

Animal activists, including those on the city’s Animal Welfare Advisory Committee, want to see councillors pass new rules for how the woodland creatures — and their dams — are handled in the city.

“Typically in London, trapping is used. That’s the archaic method,” said Deb Harris, who until last month sat on the committee and is continuing to work on the issue. “Other municipalities have employed non-lethal alternatives successfully.”

No no no, you haven’t gone back in time 5 years and history is not repeating itself. This story is from Guelph Canada. (And I just met someone who explained that this doesn’t rhyme with ‘elf’ just so you know) Ahh it brings back memories though doesn’t it?

Tempers flared in the beaver debate Monday when city staff asked council’s planning and environment committee  for permission to continue trapping the animals if they pose harm to infrastructure, like drains.

That, members of the animal welfare committee, flies in the face of a June council decision requiring that administrators trap no more beavers until a report on other means of warding off the creatures is heard.

Coun. Bud Polhill, chair of the planning committee, pulled administrators’ request off the consent agenda, asking that a report come back at a later date with more information.

Members of the animal welfare group, who said they didn’t know about the staff request until late Sunday, hope that means they’ll get a chance to state their case. They’re prepared to make a report, recommending the city consider using tools to ward off the wildlife instead of removing those that pose a threat.

Oh how exciting! Tempers flaring! City staff pontificating! Passionate pedestrians protesting! Are these meetings video taped? I’d love to watch with some popcorn and a nice  bottle of this…

Need more good news? The proofs came this weekend for our historic beaver prevalence articles…we are really being published – which means a century of misunderstanding is really about to be overturned!
