You’ve heard of a red letter day? Well yesterday was a red-beaver day. Here at beaver central we are good at picking up trends and regional changes. We’re usually at the front of the line when it comes to hearing good news. But I’ll be honest, I never expected this.

Draper Fight Centers On Beaver Dams, Wetlands, Flood Control

Two, small beaver dams lie at the heart of a quarrel in Draper. County flood officials are ordering residents to take them down. But the homeowners say the dams protect the wildlife and value of their homes.

Kelly McAdams says the notice of violation letter came on Christmas Eve.

“Inspection by Salt Lake County Flood Control,” he says, reading from the letter, “has indicated that fallen tree limbs and debris have been deposited in the form of a beaver dam into Big Willow Creek, a county-wide drainage facility, without authorization.”

Next month, McAdams goes before an administrative law judge and expects to lose, considering beavers and wetlands have no standing in county law. But he and his wife are set on preserving this patch of habitat for the beavers and all the other creatures that rely on this wetland wonderland.

Make sure you listen to the story which made NPR this morning and sign the petition, then check out SLTribune.

Leave it to beaver? No way, says Salt Lake County

Draper • Big Willow Creek bends and meanders behind Kelly McAdams’ Draper home and her backyard steps down into an urban wildlife preserve.

Thanks to a string of beaver dams, the creek pools into wetlands teaming with life. Ducks and geese nest on the banks lined with cattails; herons and pelicans visit to dine on the 18-inch carp and catfish. Neighborhood kids also fish the ponds.

But where McAdams, his wife, Kris Burns, and neighbors on Dunning Court see an ecological sanctuary, Salt Lake County sees “unauthorized modifications to a countywide drainage facility.”

The county Division of Flood Control has ordered them to remove the dams or face a $25-a-day fine, even though federal wildlife officials say these dams enhance the water quality, hydraulics and riparian habitat

The waterways and channels need to be clear and run and serve their purposes. There is a balancing act,” Graham said. “The county has demonstrated many times it balances wildlife habitat on creeks and waterways as they run through the city.”

Graham has overruled McAdams’ appeal, which is slated to go before an administrative law judge on April 26.

Because my life is just like that I had already heard about this case from the real estate agent representing them who contacted me on April 1 looking for supportive letters to the court on the issue of beavers, water storage, and biodiversity. I put out the usual appeal for help to our beaver friends in Utah but with this new flurry of news I heard this morning from Mary Obrien who is on it. Joe Wheaton is in Europe but I’m hoping he can contribute or at least assign a student to do so. I also heard from our retired attorney friend who won the famous Lake Skinner Beaver case at the appellate level that he would be happy to talk to them and has some ideas to pursue.

“You have all these ecosystem services that keep the entire stream corridor functioning as it should,” said Jones, with the Wild Utah Project. “Many other municipalities across the county are starting to allow beavers back to perform this critical engineering service.”

Meanwhile I know Worth A Dam will write something and mention how a Contra Costa County Flood Control Specialist was on our beaver subcommittee and approved the flow device that controlled flooding and washouts for nearly a decade. I have personally contacted everyone I can think of that might help ‘circle the wagons’ in this case, but more is always needed. If you want to help, email me and I’ll give you contact info. The entire Tribune article is excellent and even talks about flow devices but y requires a little persistent to get past their subscriber wall.

Meanwhile, completely independently but not unrelated, I heard from Michael Pollock yesterday about this prayer-answering article from the unlookedfor source of BeefProducer newsletter. No seriously. It is beautifully written by Editor Alan Newport and he starts out with one of the VERY best lines I’ve ever read. Send this article to every old curmudgeon you know who won’t listen to reason.

In defense of beavers

To reverse streambed erosion the hated beaver is the most likely candidate.

Beavers are the cure we don’t want to take.

No matter how much we improve our grazing, no matter how many water-control structures we build, our streams and other watercourses will cut deeper and deeper into the landscape, robbing us of soil and drying out our pastures and fields.

It took me many years of study and observation to come to this point in my thinking, but today there is no longer any question in my mind. Read on and you’ll learn why I say so.

I’m almost 60 years old and throughout those years I’ve watched the streams cut deeper and deeper into the soil near my home. On my uncle and aunt’s farm, the little rocky crossing we walked across and drove tractors across and rode horses across without a thought disappeared years ago into a gulch. The entire creek today is much deeper than it was, and so is every other creek, stream and wash I know of.

So the question, I reasoned, was what process had previously stopped this from being a natural course of events that outpaced the normal upturn of new soil through movement of the earth’s crust?

In North America, the only answer I‘ve ever found was … beavers! They once lived by the millions in every state in the union, and new evidence says their homeland stretched across much of Mexico and into the arctic tundra of Canada. I have more recently learned beavers also were common across Europe and Asia.

With all this in our knowledge base now, it seems if beavers were the agent of change and good in streams for hundreds of thousands of years before we arrived, then they could be and should be again. They work day and night, like the cow, without us lifting a finger.

I understand that beavers are a pain in the neck, but so is erosion and droughty land.

I have no particular love for beavers, but I do love the land and God’s creation. It’s my understanding we are to be stewards in His image. So here I stand, saying kind things about one of the most hated creatures in the world of agriculture.

Go read the whole article. And then read it again. It’s really well written and contains an impressive amount of research. It’s even more impressive when you realize that Alan is the editor of BeefProducer and lives in Oklahoma. Meanwhile I’m going to be busy thinking up a graphic for that AWESOME first line and writing my amicus brief to the court in Utah.

Then I may just lie back and smoke a cigarette. This has been an incredible morning.

Beaver Trash and Treasure

A spoonful of sugar helps the medicine go down right? Let’s have something sweet and something not-so-sweet today because beavers face all kind of receptions. Here’s the response they’re getting in a park in Madison Wisconsin, because really who ever heard of wildlife in a park!

Beavers create controversy at Madison park

They say, in addition to tree damage, beavers often build dams that could create flooding across the park. With raised water levels, that could also increase the likelihood of fish dying.

People also say they’re upset the public was not notified. The city says trapping is a longstanding wildlife management practice. They says it’s not practical to have a public process prior to each instance of trapping being authorized, given the timing of a quick response.

That’s right, the mean beavers will make the water too deep and the fish might drown! And we do this all the time whenever we want to so don’t complain! We’re glad at least that people are upset about this. Because anytime people are forced to talk about their silly decisions on the nightly news there is a spark of hope the right people will think about changing.

Necessity may be the mother of invention. But discomfort is the precursor to listening.

Well, pay attention. You should take a lesson from two states (and some lakes) folks really paid attention to Joe Wheaton teaching about beaver benefits. Not clear why this article is being written in Pennsylvania but I’m sure glad it is.

To Aid Streams Simply, Think Like a Beaver

A buck-toothed rodent could teach people a thing or two about stream restoration.

Beavers have been building dams along North American streams for centuries, and their habits suggest cheap, simple ways to improve water quality, said Joseph Wheaton, an associate professor of watershed sciences at Utah State University.

Most current stream restoration practices are costly and require heavy machinery to rework small tracts of land.

“I would argue we spend that money so disproportionately on little postage-stamp restoration projects here and there, leaving millions of miles of streams neglected,” Wheaton said during a March 22 USDA webinar.

Wow, it was a webinar that inspired this article? Good work, somebody was paying attention. I wonder who. The author, Philip Gruber? He’s a staff writer, but maybe one with a eye on this? The only other name mentioned in the article is a sage brush specialist from Portland, Jeremy Maestas.Someone who works for Lancaster Farming wanted this written, and I, for one, am thrilled. Pennsylvania is one big kill-beavers state, so it’s remarkable. Dr. Wheaton must have been very convincing.

Beavers have contributed to those changes in the course of streams. To keep safe from predators, beavers like to have an underwater entrance to their above-water lodge. If the water is not deep enough to have such an entrance — often the case on headwater streams — beavers build dams to make it work.

Beavers are found across much of North America, almost anywhere there’s water and wood. They are well-established in most areas of Pennsylvania.

In places where they aren’t, such as Lancaster and Berks counties, excessive trapping and landowners’ distaste for beaver damage are the main reasons, according to a 2008 report by the Pennsylvania Game Commission.

The idea of using beavers as conservation accomplices dates back at least 60 years, when Idaho parachuted beavers into a wilderness area to improve trout habitat and reduce the risk of flooding.

That turned out to be fairly cheap and effective, Wheaton said, although he isn’t necessarily prescribing a furry air drop for Kutztown or Quarryville.

Humans can build beaver-damlike structures themselves with logs and large woody debris.

These structures can slow down a “bowling alley of a stream” and turn it into a more complex, more gently flowing habitat, he said.

Dubbed beaver dam analogues, these structures can be built with hand labor. Even volunteers and children can get involved — no heavy machinery required.

A beaver dam analogue can easily be adapted to fit the location, and it’s relatively simple to build a complex of dams as beavers often do, Wheaton said.

Considering they are made of raw wood, beaver dam analogues don’t have a super long life span — one to 10 years, depending on conditions.

That’s OK, Wheaton said. “Sometimes the failure of these dams produces some of the best habitat.”

Wait for it…here comes my favorite part.

Artificial beaver dams don’t work quite as well as actual beaver dams do, so once people have laid the groundwork, it often is possible to turn the conservation work over to the critters themselves.

HERE ENDETH THE LESSON. The moral of the story is that you can get your buddies together and run around cutting up trees and pretending to be beavers every few years or you can simply stop killing the animals and let the be themselves, making repairs as needed and constantly improving their work.

Which one sounds easier to you?

No Retirement for Beavers

I know it’s not Sunday but there’s plenty of good beaver news to go around. Starting with this article from Muskoka in Ontario, Canada. It is nicely written by Andrew Hind, who obviously has come to appreciate our flat-tailed friend.

Muskoka beavers build a healthier environment

Despite being a Canadian icon and a symbol of industriousness, many people view the beaver as a nuisance animal, blaming them for flooding and for damaging property through the felling of trees. Any derision towards the beaver, which generally is misplaced and based more upon myth than reality, masks the absolutely vital role beavers plays in creating a healthy environment – especially in areas with lots of wilderness and wildlife, like Muskoka.

Beavers spend much of their life building and maintaining dams that hold back the water and create the ponds in which they live. What most people fail to realize is that the beaver is not the only one to benefit from the habitat it creates.

The contributions made by beavers, perhaps nature’s most industrious animals, are more profound than most people realize. They are not the nuisance they are so often made out to be, but rather our partners in preserving the health of our planet Earth.

“The beaver is the largest rodent in North America and it has been commonly known as ‘nature’s-engineers’ because of what they do for the environment,” explains Muskoka naturalist Robin Tapley. “A beaver is the only other mammal besides man that alters its environment to suit its living requirements. However, in the case of the beaver, its contribution has a positive impact on the local flora and fauna and this greatly increases the biodiversity in an ever-shrinking natural world. Science has demonstrated that the result of a single dam has increased the number of birds, reptiles, mammals as large as deer and bears, and plant life in areas modified by beavers.”

Are you smiling yet? This is a ‘second cup of coffee’ kind of read and a great way to start the weekend. What I love about an article like this is the fact that you can tell right away it’s going to be good. And you are just curious how good?

Dave McLachlin, a biologist for Ducks Unlimited, enthusiastically agrees. “Beavers are what we call a ‘keystone species. Without them we would witness a collapse of the ecosystem. The wetlands that beavers help create are the most productive environment we have in Canada.”

Beaver ponds not only create biodiversity, but also help with local flood control, reduction of water turbidity, the filtration of herbicides and pesticides, and – eventually – the creation of fertile bottomland.

To understand the importance of the beaver pond to the local system we need to understand more about the life cycle of these ponds.

Some people view the appearance of a dam in a stream almost as a sign of rodent infestation, a nuisance that needs to be removed. Many even believe that the dam and the pond it creates will eventually lead to destructive flooding downstream. Tapley bristles at the notion that the appearance of a beaver dam is a blight on the environment.

“A beaver dam is a complex structure designed specifically to slow the flow of water in a stream that results in creating a pond or wetland. Unfortunately, in the eyes of humans, flooded lands and fallen trees (specifically aspens, which is the tree of choice for beavers) appear to be an attack on the land. However, this is far from reality. The stumps grow new shoots which are a favoured food of moose and white tail deer, snags or dead standing trees become prime nesting locations for cavity nesters, including woodpeckers, wood ducks and mergansers, and the resulting wetlands offer increased habitat for insects, amphibians and reptiles, osprey, blue herons, mind and more – in fact, 85 per cent of all North American fauna rely on wetlands,” he explains.

Beaver dams, he explains, do not cause flooding – just the opposite. They help control the flow of water in the surrounding area, facilitating flood control in times of high water and also help maintain a stable water table, making streams, ponds and marshes less vulnerable to drought.

Give it up for Dave from Ducks Unlimited! He clearly understand beaver benefits and the good they do. The article goes on to take a little detour from accuracy describing how the “male beavers disperse for long distances looking to start their own family”. (Which of course would never be possible for heterosexual beavers unless the females did it too.) But never mind that Dietland Muller Swarze wrote that beavers were very unusual in that the female disperers went farther than the males. (The only other animal where girls go farther is porcupines, which is just the kind of odd fact that stays in my brain.) Dave gets the important bits right on the money.

The sediment and debris captured within the pond settle to the bottom, making for better turbidity and allowing for a huge variety of protozoan and insect life. Turtles, fish, and bullfrogs and fish love these deeper waters. Larger snakes begin to arrive, taking advantage of the abundance of frogs. The grassy areas around the edges of the pond, meanwhile, make for ideal nesting habitat for waterfowl, such as ducks and Canada Geese. These same grassy areas are attractive to small rodents, which are in turn prey for marsh hawks and foxes. In just a short period of time an amazing diversity of wildlife calls the beaver pond home.

The heightened wildlife activity centred on the beaver pond confirms its importance in biodiversity and maintenance of wetlands. In fact, Ducks Unlimited, which has a mandate to protect duck populations, recognizes the value of working with beavers to restore wetlands and the symbiotic relationship between healthy duck and beaver populations.

“The habitat resulting from beaver activity is tremendous. Not only do so many species depend on it for food, shelter and breeding grounds but research has shown that bacteria attracted to a mature beaver pond helps remove nutrients (phosphates and nitrates) contained in the runoff from nearby farms, making for cleaner water. Herbicides and pesticides are also removed in a similar way,” notes McLachlin.

Beaver ponds are cyclical, however, and come and go. “Eventually the beavers move on and the dam breaks down, draining the water and leaving behind an extremely lush meadow and the cycle begins all over again,” explains Tapley.

And yet the one-time pond continues to pay rich dividends for the environment. The meadow – its soil consisting of muck that sat submerged on the pond’s bottom – is rich in nutrients and provides fertile ground for seed blown upon the winds. As a result, it doesn’t take long before there is enough lush vegetation for deer to begin grazing. Tree seedlings soon take hold. In about 15 more years a beaver meadow has formed. If left undisturbed, the area is likely to once again play host to beavers once trees have matured to about 10 centimetres in diameter.

Early Muskoka farmers appreciated the value of these rich bottomlands and cultivated them for raising crops. They reaped the bounty of more than a decade of labour by a colony of beavers.

So not only do beavers benefit all that wildlife when they’re actually in residence, when the pond silts up and is abandoned, the soil they leave behind is the rich loam farmers love best. And in between making ideal grow conditions and removing nitrogen beaver dams also prevent flooding. Are you sold yet? It’s wonderful to see an article like this appear out of nowhere. I usually hear something in the pipeline along the way, but this was a completely un-looked-for blessing. Go read the whole thing so Mr. Hind is reminded that folks care about beavers.

And late breaking I was just sent this by writer Ben Goldfarb who will be meeting with doctoral student Dan Kotter in Yellowstone to discuss his research. Here’s what the trail cam picked up recently, and check out Mr. Wolf at .41. Those beavers do not even trouble their pretty little (dry!) heads about him.

Plenty to do! And they’re just the critter to do it!

“To Beaver or Not to Beaver”

One of the advantages of having ‘beaver buddies’ all over the world is that there is almost always someone on hand to help me get the things I cannot reach. Like this, intriguing headline that requires a paid subscription or a passport to unravel. Fortunately for me, Chris Brooke of the Save the Free Beavers of the Tay FB group leaped to the rescue:

Beaver fever proves giant rodents are not a dam nuisance

It is a wonder that anyone wants to reintroduce beavers almost 400 years after they were hunted to extinction. They sound like a farmer’s nightmare, creating soggy fields, rotten trees and pools of standing water, and infuriate anglers, as their dams are believed to hinder fish migration.

Yet a study into their effect on flooding on a farm in Devon has led to “beaver fever”, a clamour for more, not fewer, of the huge rodents and similar trials across England.

Beavers’ dams control the flow of water after rain and act as natural filters of chemical fertilisers that run off fields. In summer they also stop streams drying up, according to researchers at Exeter University, while coppicing trees creates a patchwork of different habitats that has increased the range of plants and wild animals.

Ooh I’m liking the way this is going. Time for coffee and a comfortable chair while I explore further. Mind you, this is the largest selling ‘respectable paper’ in ALL of the UK, so I think there are going to be folks paying attention. Including all the magistrates, farmers and anglers.

Richard Brazier, who led the initial research, has been asked to carry out six feasibility studies for beaver projects in Dorset, Gloucestershire, Devon and Cornwall. “The science suggests it would benefit society to have beavers in the landscape,” he said.

Naturalists in Wales have applied for permits to release ten pairs in Carmathanshire, while beavers in Scotland have been granted native species status after similar trials in Argyll.

In Devon, the beavers built 13 dams on a 180m stretch of stream inside an enclosure. Water flowing out had 30 per cent less nitrogen than water flowing in, almost 70 per cent less sediment and 80 percent less phosphates.

“Fertiliser getting washed out of soils is a huge problem worldwide,” Professor Brazier said. “It leads to algal blooms that starve the water of oxygen, which leads to fish deaths. It’s one of the reasons we have to treat our drinking water.”

If the difficult beavers of South America are the nagging critical aunt of the beaver world who’s petty complaints you just can’t escape, the epic “TO BEAVER OR NOT TO BEAVER” struggle of the UK is that glowing fountain of praise from your indulgent grandmother. I love hearing them argue about this over and over again because they are repeating the pro’s with a megaphone on an international scale. I don’t want them to ever stop, because who will take their place?

The government has promised £2.5 billion for improved flood defences, including £15 million for natural flood management such as planting trees and adding bends to rivers which have been artificially straightened.

“Most of the money is being spent on concrete,” said Chris Jones, a farmer, who is planning to release beavers upstream of Ladock, in Cornwall, a village that was flooded twice in 2012. “We need our land to store more water, so we don’t have these massive pulses of water after every heavy rainfall.”

Not everybody is a fan of the animals, which can grow to 25kg. A spokesman for the Angling Trust criticised “adding more barriers to fish migration”, while the NFU opposes beaver reintroductions because of “damage to farmland … and the risks of them spreading disease”.

Mark Elliott, of Devon Wildlife Trust, said that farmers’ “biggest concern is that beavers will become a protected species. If they are going to be accepted by landowners, there have to be clear mechanisms for managing the conflicts [between the two].”

Really Mark? Is that really your ‘biggest concern’? That beavers will be protected? Wouldn’t a bigger concern be that there wouldn’t be beavers at all? Or that all your rivers will dry up and that global warming will make it too arid to have them there anyway? Or that Theresa May will turn out to be exactly like Trump. How could the protection of beavers be your BIGGEST concern?

Okay, I’ll give Mark a break. Maybe that was a misquote or taken out of context. Maybe you’re having an off day or your cat is in the vet. It’s mostly a wonderful article. And I’m still very happy about it. We all should be!

Finally! The article about our beaver tenure came out! Of course it arrived the moment after I posted yesterday, but it’s perfect for our only-good-news-Sunday. It’s also a well written article by Martinez resident Sam Richards. (Turns out he lives next-door to the house where I grew up – because Martinez!) It is accompanied by Susan Pollard’s wonderful photos and I don’t sound as horrible as I was worried might happen, but I’m never happy when Luigi talks about feeding beavers with a stick. If you want to see the video where I look positively slagged you are going to have to click on the link to find it yourself. I manage one good line at the end, anyway.

A decade of beavers (mostly) in Martinez

MARTINEZ — It started in 2007, when downtown Martinez citizens noticed Alhambra Creek was flowing slow, and that trees along the banks had been gnawed down to little points. The furry, buoyant culprits were elusive at first, but their first dam of sticks, leaves and mud near Marina Vista Avenue told the, er, tail.

After winning an early fight over their very lives, given concerns about downtown flooding, the beavers went from cause celebre to cause for adoration. There were (and are) “Martinez Beavers” T-shirts and bumper stickers, and the 10th annual Beaver Festival will take place in August.

“Who had even heard of beavers in town before?” said Heidi Perryman, president of the nonprofit Worth a Dam group. Someone she met literally walking down the street told her that beavers lived a few blocks from her Martinez home.

“It’s actually pretty common, it turns out, but I didn’t know it then,” said Perryman, whose preservation efforts have helped give the local beavers a dash of national notoriety, and even some international interest, given the recently rejuvenated efforts to reintroduce Eurasian beavers in England, where they had been extinct since the 1500s, killed for their pelts (and as an acceptable edible substitute for fish during Lent).

“It’s been both a feel-good and a do-good story for Martinez,” said City Councilman Mark Ross, an early champion of the beavers. The rodents themselves have, by and large, done well in the creek; the creek’s ecology has indeed improved, say environmentalists who credit the beavers; and Martinez has become known for something beyond Joe DiMaggio, John Muir and the Shell oil refinery.

A feel good story for Martinez! Thank you for that quote Mr. Ross, I think I’ll put it in my city grant application. It’s nice to see the story remembered in such detail. I sent the reporter a copy of our newsletter which prompted him to think about it. Like pretty much everyone, he had no idea ten years had passed already.

At Luigi’s Deli, about a block from Alhambra Creek, a wall is packed with photos of people owner Luigi Daberdaku has met over the years. Most of them, he said, came downtown to find the beavers.

It didn’t take long for the beavers to win his and others’ hearts. Daberdaku fed them apple pieces — on a long stick. “I saw what the teeth did to the trees; what could they do to my hand?”

At a November 2007 meeting at Alhambra High School, David Frey of Pleasant Hill, a maritme consultant, suggested Martinez city engineers build a diversion around the beaver dam so the beavers don’t have to be relocated. The “beaver deceiver” built the next year accomplished just that. Dan Rosenstrauch/Staff archives

Daberdaku didn’t support downtown property owners who initially wanted the beavers gone. Neither did most who spoke at a rowdy November 2007 City Council meeting at Alhambra High School, where everything from moving the beavers to embracing their tourism potential to renaming the high school sports teams from the Bulldogs to the Beavers was discussed. Many invoked the name of a famous environmentalist son: “What would John Muir do?” One woman said, “We don’t want to be known as a refinery town that kills beavers, right?”

Former Martinez mayor Harriett Burt said learning the science of the beavers changed her mind. “It raised awareness about the creek environment in general,” she said recently, “and it’s been a good thing.”

Good Harriet! And Bad Luigi! I remember the night we caught him feeding apples with a stick and told him to stop. I hoped that was the only time. But that’s what happens when an entire city raises beavers. Not everyone is a good parent. The reporter even talked to Skip, which I’m sure amused him.

But the beavers’ real stay of execution may have been the “beaver deceiver,” a water bypass pipe under a dam, installed by Vermonter Skip Lisle in 2008. Designed to fool beavers into thinking they’re successfully damming a waterway, the pipe “secretly” carries water under the dam to prevent flooding.

Lisle still marvels at his Martinez assignment. “I was building a beaver deceiver, and there were throngs of people there, media, and helicopters overhead. It was unique.”

Perryman and the Worth a Dam group have kept beavers in the public eye, even when they were absent from Alhambra Creek. Beavers’ images adorn downtown murals at one creek crossing, and on a “tile bridge” downstream with children’s depictions of the beavers. The Martinez Beaver Festival, an intimate gathering at its 2008 beginning, now draws hundreds to the small patch near the Amtrak station that some call “Beaver Park.” For two years, a group from Oakland led by a city environmental stewardship analyst took the train to Martinez for lessons on how beavers renew urban streams.

Worth a Dam has also inspired other beaver champions. Caitlin McCombs found that group’s work while looking for help saving beavers near her home in Mountain House, near Tracy. McCombs then started the MH Beavers preservation group.

“I never knew before that beavers serve as a vital keystone, and that they promote an overall healthier environment,” said McCombs.

Caitlin! What a wonderful quote! We are so proud to have been part of your V.I.B.E. (Very Important Beaver Education). She won’t be joining us for earth day this year because she has a conference to attend for college, and we will miss her. But I feel that we helped her raise the awareness in Mountain House and she will think differently about beavers for her entire life. That makes me entirely happy.

By October 2015, the beavers were no longer deceived by the black pipe and built new dams downstream before leaving altogether soon after that. Some of the 24 Martinez kits had died, and others moved on. The original mother beaver, with a new younger mate, left, too.

But Perryman and others were overjoyed when, on March 5, a beaver was seen in the creek near downtown. It’s been seen at least twice since, and photographed at least once.

Does this mean they’re back? With three verified sightings, Perryman says yes.

Then again, were they ever really “gone?” While registering for a marathon recently, Councilman Ross said he was from Martinez. “The guy … said to me, ‘How are those beavers?’ Everywhere you go, the legacy of the beavers remains.”

Beaver legacy! That’s what we have. Of course., I’d rather have the actual beavers, but hey, it’s way more than most cities ever get. Thank you Sam for another fine reminder the beavers promote a city’s good nature. And thank the beavers for being such great sports for a decade even though the city installed a wall of metal through their lodge. What a crazy, beautiful way to spend a decade of your life!

Time for some lovely donations to the silent auction. This week’s treasures come from Litographs in Cambridge Massachusetts. They are a remarkable business I happen to love because they turn favorite literature into wearable art. Literally. The entire text of a beloved book becomes a shirt, card, poster, tote or scarf. Catcher in the Rye, Scarlet Letter, Jane Eyre, Hamlet, The Princess Bride, classic or contemporary.

“We founded Litographs because we had a vision of bringing our favorite literature off the page, onto your walls, and into your wardrobe. We believe in sharing the power of books with more people.“

This is the entire text of Herman Melville’s “Moby Dick” which they generously gave beautifully matted and ready for framing.

Long ago I had a conversation with owner Danny Fein about possibly working with the now-public-domain text “In Beaver World” by Enos Mills. While he wasn’t sure this was a project they would tackle any time soon, he personally made this for our event. Look closely because that is the entire book. Thank you Danny and friends at Litographs! For this beautiful addition to our silent auction.
