Nice article in the Gazette might help nudge the mural forward….

Questions surround beavers as upcoming mural celebrates legacy

Although an alleged recent sighting of a lone beaver in Martinez might bring some hope for their return, it still seems no answers have been forthcoming regarding the sudden disappearance of the Alhambra Creek beaver colony late last year.

According to Heidi Perryman of Worth a Dam, a beaver was spotted near Creek Monkey Taphouse on February 18 by a Martinez resident. The sighting is the first reported since September of last year, around the time when several young beavers suddenly and inexplicably died in the Alhambra Creek. During that time several adult beavers also disappeared, leaving the creek void of beavers for months.

Perryman says the lone beaver is likely what is known as a “disperser,” a young beaver seeking territory to mark as his or her own. She explained that currently there is no evidence that the beaver decided to stay in the creek.

Months ago, the California Department of Fish and Game oversaw the necropsy performed on a young beaver at UC Davis, however tests were inconclusive. Disease, toxins, and some poisons were all ruled out as well.

While it seems no answers or progress have been made on determining the cause of the beaver deaths, Perryman and Worth a Dam are hoping to honor their legacy in Martinez.

Worth a Dam has been working with the city on a wildlife and beaver mural to adorn the cement surface of Marina Vista Bridge Wall. Back in November Perryman pitched the idea to the PRMCC of a mural located on the south facing side of the Marina Vista Bridge at Alhambra Creek.

“The beavers made a real impact on Martinez, and that’s something we want to capture with this mural,” said Perryman. She hopes the mural reminds people of the “living creek” that runs through the center of downtown Martinez.

The artist for the mural is Mario Alfaro, who has also worked on the Joe DiMaggio mural on the Main Street Plaza Bridge. The cost of the mural will be covered by Worth a Dam for a total of $6,000. The organization hopes to cover the cost with grants.

The art committee of the PRMCC approved the mural design, so the next steps come with the city council. Perryman noted that, because the city council meeting agenda is fully booked for the month of March, the project likely won’t be on the council agenda until April.

I’m always happy when accurate and positive information about the beavers and Worth A Dam is printed. Thanks, Joseph Bustos. You made the mural even more inevitable by linking it in the press to the loss of the beavers. Hopefully it will help nudge us a little farther along queue for getting on the Agenda for city council! Fingers crossed.

Imagine how surprised I was to come across this yesterday with the help of a friend. I don’t know how I missed it in the flurry of the holidays and retirement. But imagine how especially surprised I was to read the bold sentence from Dr. Michael Pollock himself;

Manmade Beaver Dams Save Fish

At Wenas Creek, they are putting in manmade beaver-dam analogues by pounding posts into the streambed and then weaving branches among them. A few workers can run a post pounder with biodegradable hydraulic fluid and achieve hydrological results similar to those of an imported-beaver colony. The result, says Tobin, is that, “fish and farms coexist in the same reach.”

The natural solution: beavers. In the past, “problem” beavers have been relocated to streams in need. Their dams back up the water, raising streambeds while still allowing passage for salmonids. The downside is that it costs money to trap beavers and house them prior to relocation, and despite the offer of seemingly ideal habitat, they sometimes leave. Besides, says Tobin, manager of the North Yakima Conservation District, “you can’t control where they’re backing up water.”

Enter Michael Pollock of the National Oceanic and Atmospheric Administration, who pioneered the idea of reinforcing blown-out beaver dams with posts. “That’s the best strategy, because they’ve already done all the work,” says Pollock. “We’re just reducing the dams’ failure rate.”

Pollock suggested dispensing with beavers altogether.

SACRILEGE! Some one hand me the smelling salts, I’m feeling faint. And tell me, how are repairs going to be made on those dams once injury occurs? Will a team of humans be living on sight just in case? Will they also dig in the mud to encourage invertebrates? And how will the trees coppice with no one to chew them?

Of course a sentence like that could NOT go unchallenged. So I sent him this last night:

With the exception of this aberrant infraction, he’s still mostly a good guy and at his heart a beaver believer. He quickly wrote back:

You are having way too much fun with your new found skills. 🙂

Which I confess, is wholly true. That was the most fun I had all week.

The results of a Trickledown Economy that works!

More great coverage of the otter recovery out of Sonoma. Humans are happily taking credit for restoring the streams and improving their fish, but I’m guessing they had some other flat-tailed helpers along the way. Great photo from beaver friend Tom Reynolds too.

River otters coming back to Sonoma County

Winter rains have swollen streams and rivers, recharging groundwater, filling ponds and lakes, and making more visible the network of waterways that traverse Sonoma County. One species that makes good use of this aquatic web is the river otter. Have you seen a river otter recently? If so, you’re one of a growing number because river otters are on the comeback.

The Bay Area is seeing a rebound in river otter populations. Experts speculate that this is a testimony to many overlapping efforts to improve water quality and restore habitat. Megan Isadore of the River Otter Ecology Project says, “The most amazing thing about the otters’ return is they have done it completely on their own. There have been no efforts to reintroduce otters. What we are seeing is the response of the species to improved conditions.”

This time of year, female otters are denning and having pups. Maternal dens can be under large fallen trees or even inside old beaver dams. Each female gives birth to between one and four pups and then, shortly after, will breed with a male in preparation for the following winter. One amazing fact is that females experience “delayed implantation,” harboring fertilized eggs and then keeping the pregnancy dormant for up to 10 months.

Most young otters live with their moms for at least a year, with females often staying to act as helpers with the new pups. Young adult males leave after a year and strike out on their own to find and establish their own territory. Otter observations are often made during the February through March time frame as these disbursing juveniles take chances crossing subdivisions, ridges, roads and farm fields in search of a new and abundant source of fish.

Otters have benefited from on-the-ground habitat improvements and from the evolution of environmental policy. In 1961, California outlawed commercial otter trapping. Otters were trapped for two reasons: to sell their rich, thick pelts to the garment industry and sometimes to protect localized fish populations. Otters have large home ranges and are constantly on the move, so large scale fish populations remain intact even if individual fishing holes get temporarily depleted.

Another policy assist came from the 1972 passage of the Clean Water Act. This ushered in a generation of investments in cleaning the bay and eliminating many sources of industrial and agricultural pollution. Like bald eagles and peregrine falcons, otters illustrate that policy decisions do matter, and that we can repair degraded environments. As recently as 1995, state maps did not even show Marin and Sonoma counties as part of the river otter’s range. Today, scientists confirm that otters occupy much of their former Bay Area territory.

We’ve all benefited from the evolution of environmental policy, that’s for sure. But I’m also thinking that the recovery of another mammal who actually happens to make the water cleaner and increase the fish population might have helped a little too. (Ahem). Congratulations to Meghan Isadore and her merry band of Otter Spotters at the River Otter Ecology Project. We’re always happy when creeks draw human eyes!

Here’s a lovely promotional message from an otter himself demonstrating who he believes has helped his survival. Just look at the shapes he is posing under for a clue about who he thinks helped him most. This video by Moses Silva on Valentine’s day a few years ago shows an otter grooming atop the old beaver lodge.

Although, if otter trapping has really been outlawed 55 years in this state I’d be cautious about how much promotion of their “healthy recovery” I’d want to do in the media. Just sayin’. The nearly extinguished beaver population was protected for all of around 11 years and they decided the population had rebounded enough to restore trapping. River otters have been spared in California for more than half a century!

Ixnay on the opulation-pay evovery-ray is my advice.

Invoking the past to change the future

Leave it to Louise Ramsay of Scotland to tie it all together. Beautiful, writing that echoes with history and foreshadow.

Beavers and the conflict in the Scottish countryside

Last July, Alyth flooded badly and a young farmer started a rumour that the beavers on our land had exacerbated the flood. He tweeted his theory to the media and the story spread like wildfire, though very few locals believed it: apart from anything else, it was clear that upstream beaver dams had all held firm.

SNH then commissioned a study that showed the beavers were not to blame. But this month things got even better when research that has been done on our land over the last 13 years by Stirling University was published and the beavers were not just exonerated, but shown to actually slow floodwaters and thus reduce the impact of flooding, as well as increasing biodiversity & soil retention and stripping out pollutants.

Of course, for these farmers the presence of beavers is something real in a way that for the majority of people it isn’t. They have to deal with beavers busily trying to re-wild their land, to slow the flow of water in their ditches which are meant to hurry water off the fields as fast as possible. They have to confront the beavers’ desire to create wildlife rich, bee loud, water purifying wetland habitat by backing water up into the edges and hollows of their valuable arable fields, and they are not over the moon about it.

Lets pause a minute just to savor the delicious word choice at work here. The innocuous and unassuming phrase “bee loud” just appears to be an oddly phrased reference to noisy insects, unless you are familiar with arguably the most famous poem describing longing for rural life in the context of the city that was ever written. You may know it as the Lake at Innisfree. Do not think, for one moment, that it was by accident Louise evoked that hymnal of longing for a wild life. She wants the reader to remember their own longing clover and clear water. Here’s Mr. Yeats himself singing his words.

People remember more farmland birds in the past, more butterflies, more flowers, more bees. Now they see farming methods which use artificial fertilisers produced by the use of large amounts of fossil fuels, raided from the earth, set alight and polluting the sky. They see huge tractors with deep ploughs churning the earth, and they see brown water flowing off the land in times of flood and brown dust blowing in the air in dry summers. They worry that the very soil on which our food security depends, is in danger of impoverishment, and of being blown away or washed out to sea. They worry rightly. This kind of farming which has been the prevalent kind for the last 50 years, is extractive not regenerative. According to a Sheffield University study published in the Farmers Weekly it has left us with soils that in many cases just have 100 harvests left.

Meanwhile uphill, on the sheep farms, we landowners are also under scrutiny from the progressively larger sector of the public that is getting its head round the thorny questions of flood prevention and biodiversity loss in the uplands. Sheep farming has been carried out in some of our hills for hundreds of years, often responsibly and with great dedication, and some sheep farmers are not surprisingly upset to be told they are ‘sheepwrecking’ the countryside. But as globalization hits the price the farmer gets for lamb it becomes difficult to justify economically such a highly subsidized traditional activity, and as climate change progresses it becomes harder to defend environmentally, especially in our highest and most vulnerable landscapes.

As organisations like Nourish Scotland know all too well, we need to take a long hard look at agriculture and try and be more rational and less traditional in our approach. We need to look back, but also forward to new kinds of farming being tried around the world. We need to consider the true costs of various kinds of farming and see whether they can really justify the impacts they have by the food security they offer us. Ask again whether its true that higher productivity of industrial farming really gives it the edge over organic farming. Look at the possibilities for influencing what people eat and steer them towards food grown in the least extractive, most regenerative ways.

With climate change, its causes and its effects, fossil fuels and flooding, or drought or storms, everything has to change. We can’t go on as we are just watching it get worse and we farmers and landowners, who after all have a far bigger impact than most people, a far greater chance to make a difference for good or bad, really need to start listening to what the rest of the population are saying and change our ways before things get any worse. Just for a small but symbolic start let’s hope by the time you are reading this beavers will be legally protected in Scotland and the farmers will be applying their pragmatic minds to the question of mitigation rather than getting their guns out of the locked cupboard and heading for the waters edge at dusk.

Beautiful summing up Louise! You have embroidered the separate threads of beavers, food politics, climate change and biodiversity into a delicate and powerful coat of arms for supporters to brandish in united sensibility. This was a well done piece of inspiration and perspiration and we here in Martinez could not be more impressed! I hope this finely crafted article gets all the audience it deserves!

Poor France. They are too busy eating nice food and rejecting refugees that they haven’t any time left to finish a complete thought. The harried things can only have half-ideas and not carry them thru to their logical conclusions. Descartes would be so disappointed.

Beavers threaten water supply

A BEAVER colony is threatening the water supply of the 40,000 residents of a town in the Ardennes.The animals, who have lived in the area for two years, set up their first dam in November across the River Audry.

Since then they have added another six to their roster, across tributaries to the river.

Their work means that during heavy rain the rivers frequently burst their banks, taking detritus and pollution on a new course into the local reservoir – the water supply for the 40,000 people of Charleville-Mézières.

That’s right, those 6 dams block sediment and pollution from getting into the reservoir for most of the year – but when they wash out all that bad stuff whooshes down stream at once. What the article doesn’t say (because of their unfinished-thought-affliction) is that if only the beavers weren’t there the waterway could release gradual toxins all year long into the water supply. You know, like they’re supposed to.

Dam beavers!

Out in Napa the beavers are so busy ruining things that they are cramming the waterways with fish, which attracts other nuisances who gut and shit their fish into the water without any respect for the reservoirs. Take this photo from Rusty Cohn and this short video from Robin Ellison: classic examples of the many troubles beavers bring!

Mr and Mrs HM — Hooded Merganser pair: Rusty Cohn

And it gets worse. Yesterday, Dr. Ellen Wohl send me this video taken by her student documenting beaver activity at Crystal Creek in Yellowstone National Park. I know you’ll be SHOCKED to see all the riffraff beaver bring to that pristine wilderness! Thank goodness France, Martinez and Napa will probably be spared these particular visitors!

“Like beavers that pass in the night…”

This video shows a young European beaver being released back into the stream. It was posted by Bob Smith of Nature Nuts on the occasion of his retirement from the board of trustees on Scotlands Wild Beaver Group. The best laid plan of mice and men gang aft a’gley I guess.

Most likely you know of him from this program which was very delightful and well received. He lead hundreds of tours and field trips over the years. And was a staunch defender of the beavers. But wildlife advocates don’t always make the best team players. I assume there were personal reasons for the resignation. I’m aware there were factions on the Tayside beavers too, just as, over the many years, there were reasons for Worth A Dam to shuffle its membership.

The funny thing is, I always expect beaver relationships to last forever, you know like marriages, and am always surprised to learn that people get frustrated, grow apart or decide to do their own thing, (you know, like marriages).

I guess you never know who is a friend-for-life and who is just passing through. I wish we did. I wish people had clearly marked expiration labels on their foreheads so that you’d know “this person is going to provide a valuable service and then move on and you will never see them again.” Or “don’t get too annoyed about this person because they’ll be gone in a month”. I can’t tell you how many friends and strangers have helped with the beaver festival over the years, and I thought Oh good! Finally, we connected and now I can ask them for help again next year, only to realize they had passed on to other shores.

Clearly they weren’t married to beavers. Just dating.

Well, odds are, if you’re still reading this, you’re married to beavers too. So I can tell you the good news. Worth A Dam has been named the Environmental Education group of the year by the John Muir Association. Which is a nice acknowledgment of all our hard work and much appreciated. It means we get recognized at the upcoming Earth Day event and can carry the title proudly. Technically I don’t have the blessing to make this public yet, so I won’t broadcast on FB or press releases. But only friends read this website, so I can tell you, right?

I kept it secret for three whole days, though. That’s a lot for me`.
