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

 


No wonder no one believes us. The annals of research trying to show that beavers benefit ecosystems is just too good to be true. It’s like a new issue of Goofus and Gallant, or one of those religious stories about a good child who suffers brightly with a terrible disease because of her very strong faith. A mistrustful world is never going to believe that any single animal can do that many good things for a crippled planet. They just won’t. Here’s an example:

Do Beaver Dams Impede the Movement of Trout?

Ryan L. Lokteffab, Brett B. Roperab & Joseph M. Wheaton

 Dams created by North American beavers Castor canadensis (hereafter, “beavers”) have numerous effects on stream habitat use by trout. Many of these changes to the stream are seen as positive, and many stream restoration projects seek either to reintroduce beavers or to mimic the habitat that they create. The extent to which beaver dams act as movement barriers to salmonids and whether successful dam passage differs among species are topics of frequent speculation and warrant further research. We investigated beaver dam passage by three trout species in two northern Utah streams.

So far, so good. An investigation is warranted. Let’s get to the bottom of this. Tell us the gory details. How do those rotten beaver dams ruin our streams?

Our results suggest that beaver dams are not acting as movement barriers for Bonneville Cutthroat Trout or Brook Trout but may be impeding the movements of invasive Brown Trout.

Did you get that? Not only are beaver dams NOT blocking passage of the good fish. They are also keeping out the bad ones. Who’s going to believe that, I ask you? Here’s another example.

These are the Ruby Mountains of Nevada, just outside Elko where beaver friend Brock Dolman just got back from a mountain trip and exploration. He found some fantastic beaver habitat, and a species of frog that is only doing well near beaver dams. This is the Columbia Spotted Frog that is listed as endangered everywhere else.

 Here’s a little something from Fish and Wildlife on the topic.

Beaver Management

The reduction of beaver populations has been noted as an important feature in the reduction of suitable habitat for Columbia spotted frogs (Reaser 1997a, p. 39; NDOW 2006, p. 163; ODFW 2006, p. 288). Beaver are important in the creation of small pools with slow-moving water that function as habitat for frog reproduction and create wet meadows that provide foraging habitat and protective vegetation cover.

Honestly, it’s like beavers are the “Dudley Do-right” of the animal kingdom, another famous  Canadian who was a hero of unbelievable proportions that gets everything right and makes everything better without important flaws to endear them to us. Beavers are superman without kryptonite – Rooster Cogburn without the eye patch – or in the language of modern fiction, an annoying Mary Sue character without an absent parent. They do EVERYTHING right. Of course no one can believe in them.

Except us.

There were lots of fans and believers on the bridge last night, to catch the end of summer beaver show. Three kits and JR. VERY high tide. In fact, don’t ask how high it was. Ask how LOW the dam was in comparison.

The dam was so low  that both a kit and the yearling SWAM through it! Guess mom has some repairs to do this morning. Love the yearling’s little shake at the beginning.


Beaver Fever

In Glen Ellen, a colony of beavers arrives—and this time, they’re a little more welcome

by James Knight

Brace yourselves. Here at Martinez beaver central we’ve been called a lot of names in our 6 years. But this just might be the best.

A HARDY TAIL Popular beavers in Martinez set a game-changing precedent for a new family of dam-builders in Glen Ellen. – Cheryl Reynolds – Worth a Dam

In the mid-1990s, a family of beavers found their way up Sonoma Creek and settled in Glen Ellen. Although they were the first beavers that had been seen here since the animals were extirpated decades earlier, they got the same welcome that is traditionally offered to beavers: they were trapped and killed.

Then in 2006, a mating pair wandered out of the Delta and constructed a dam on Alhambra Creek in the middle of Martinez. “You could sit at Starbucks and watch the kits play,” says resident Heidi Perryman. The city council, worried about flooding, first considered the quiet, business-as-usual approach. But with so many people watching and protesting, the beavers got a stay. Perryman formed the nationwide advocacy group Worth a Dam, to help people navigate similar situations. (Her next talk on the issue is Thursday, July 11, at San Francisco’s Randall Museum.)

This article by James Knight for the Bohemian is an excellent read, you should go check out the whole thing. This is what happens when you take a little time to get the story right. (I first connected with him way back on May 3!) I suggested he follow up with Brock Dolman of the OAEC and that really gave a regional back bone for the article. Now when wine country folks spot a beaver problem, they know just who to turn to for help.

In Martinez, it isn’t just about beavers anymore. When the pond filled with fish, river otters returned to the area. Mink also turned up, along with a host of waterfowl and songbirds.

That kind of result could improve habitat for the North Coast’s federally endangered coho salmon, says Dolman. “Having grown up in Idaho and back East, I loved to fish in beaver ponds because there were a lot of fish in there. So I got to thinking: Why aren’t we talking about beavers?” While state agencies and landowners are trying to slow down stream flow and erosion with costly projects, “beavers can do it better, faster and way cheaper.” Dolman’s organization was invited to contribute beaver language to the 2012 Coho Recovery Plan.

If beavers pop out of the creek into another vineyard, it may not play out the same as last time. In Siskiyou County, Dolman says, the Department of Water Resources had requested a trapping permit almost annually for 30 years, because beaver activity interfered with a data collection point. “Two years ago, they were doing the same thing, and the biologist said, ‘Wait a minute, we’ve got to talk about this.’ They had a community meeting, created a beaver technical group, and for the first time the DWR didn’t get that permit.”

I’d  really like to think James was right, and that Martinez was a ‘game-changer’ for how we deal with beavers in northern California. Certainly some things were changed. But even in Martinez it is clear that everyone isn’t playing the same game, so changing the rules of that game just won’t effect them. If new beavers showed up in the city tomorrow do you think that they would ask Worth A Dam what to do? All we can hope is that enough folk read smart articles like this and know to hold their leaders feet to the fire long enough to nudge things in the right direction.

Speaking of nudging,  the 6th beaver festival was approved last night and the game is definitely on. Also our lovely artist Amelia Hunter was kind enough to tinker with the flyer and make the adult a little bigger.

Speaking of which, it was very high tide last night, and both dams were totally flooded. An adult beaver filmed pulling a branch through the gap of the primary and down towards the secondary!


One kit was finally spotted last night around nine. He also swam through the gap and was totally spooked by the fact that the water was rushing the wrong way! (Can solstice come any faster? This extended daylight thing is starting to get out of hand.)


Got an email this week from our friends at Madrone Audubon where Worth A Dam is officially in the newsletter for our October 15th presentation. Brock Dolman will be on first talking about why Sonoma wants beavers, and then I’ll chat about what Martinez did with them. The newsletter described us as a nationally acclaimed non-profit which certainly sounds nice, if a little exaggerate. Well, I suppose someone in the nation has acclaimed us on one occasion or another. Maybe internationally if you count Scotland and Canada?

I was pulling together my talk when I saw this. Art Wolinsky of New Hampshire has been motion-sensor filming his beavers with some amazing results. (visit his website for some tree-chopping infrared footage). The other night the beavers half chewed that big tree. Look what happens now:

And now is as good a time as any to remind you of Steve Zack and Hilary Cooke’s excellent 2008 finding that beaver dams significantly improve migratory and songbird numbers. I exchanged emails with both of them to try and urge them to come present at the beaver conference in January, but I don’t think I was persuasive enough.

Yet.


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!
