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

Suzi at workOhhh it’s so nice to be back on the HUGE familiar pc screen where everything is still broken in the usual ways. You might have to hear more from me as a result, I’m sorry to say. I thought I’d share some photos from the beaver art project taken by Suzi Eszterhas. Other photos taken that day might make it to the Ranger Rick story but she said I could share these and they’re a great introduction to a fun use of Susanna Street park.

This is Ethan who is  wearing an original Martinez beaver shirt that he made himself. He’s proudly showing his Father and son beaver bag puppets. If you wish you  could make some of your very own, the patterns are here. The paws are wooden forks. The tails and hind feet are from Dugmore’s Romance of the Beaver, but don’t forget it was Heidi’s endless labor that got them to print double sided. (The hope is that since the book is 101 years old now it will be public domain-y enough for Ranger Rick to print our pattern. And we really MIGHT have an army of beaver puppets across America.)

Bella made a beaver kit and her own frog original puppet. She knew just about everything about the bebellaavers and explained to the other children why they should use orange teeth on the older puppet. Towards the end of the event she got a little restless and went around the park picking up large sticks for her beaver to eat. It was pretty adorable.

This is Brynn who wore two charm necklaces from the past beaver festivals. She also finished thebrynn buttons this year but said that her favorite festival was two years ago when she was able to bring her best friend. If you peek to the left of the kits tail you can just make out the dragonfly and mom’s tail charms. Imagine growing up with beaver festivals. She’s been coming since she was 4.

For some reason I didn’t get photos of April and Alana from Suzi to share, but they were a dynamic duo of beaver information. April posed her beaver kit with a Fennel stalk and explained how Mom beaver liked to eat it when she was pregnant. Alana described how it might have been the salt water that killed the kits. They were both very attentive to details and asked through their grandmother if they could have their own children’s booth at the festival next year. No, really. Since I don’t have their photos to share, I will share this clip from when we met on the footbridge after the PBS beaver documentary aired. They had this feedback for the Canadian producer Jari Osborne:

Jari, btw, was delighted when I sent her this clip and wrote back on youtube:

Thank you so much, April, Alana (sp?) and Heidi!!!
Girls, I am so delighted to know you watched, enjoyed and cared about what you saw on Leave It To Beavers. It means so much to me to hear from you! ~Jari

Which just goes to show you that beaver puppets can swim a long, long way into many people’s hearts. You’ll see. Just watch.


O Gertrude, Gertrude,
When sorrows come, they come not single spies
But in battalions.

Hamlet Act IV: Scene 5

Sick baby beaver rescued in Martinez has died

Workers feed a beaver kit as it recuperates Thursday at the Lindsay Wildlife Experience in Walnut Creek. Despite workers' efforts to nurse the animal back to health, it died later Thursday. (Kristopher Skinner/Bay Area News Group) WALNUT CREEK — A sick, malnourished young beaver found on Mt. View Sanitary District property in Martinez this week has died.

The kit appeared to be on the mend, but succumbed early Thursday evening. Experts still have no idea what caused the recent mysterious deaths of four other beavers living in nearby Alhambra Creek.

Two sanitary district employees found the three-month-old beaver kit on Tuesday. It appeared to belong to a family of beavers in Moorhen Marsh, a 21-acre wetland area where the sanitary district discharges treated wastewater that is home to beavers, river otters and western pond turtles. They brought it to Kelly Davidson Chou, district biologist. The tiny critter had a runny nose and appeared lethargic and unsteady on his feet, she said.

“I was expecting a much larger beaver because it’s not the time of year you see kits of this size,” said Chou, who took the ailing animal to the Lindsay Wildlife Rehabilitation Hospital in Walnut Creek for treatment.

The young beaver was two to three pounds underweight and most likely had an upper respiratory infection, according to Guthrum Purdin, director of veterinary services at the Lindsay. Purdin was treating the kit with antibiotics and hand feeding him rodent formula containing pureed grass, soybean hulls, wheat germ and other plants.

 Four Alhambra Creek beavers, including three kits born this year, have died since July. The sudden deaths have perplexed veterinarians at the California Department of Fish and Wildlife who have ruled out rabies, pesticides, toxins, poisons and tularemia, an infectious disease commonly found in rodents.

“All we know is what it isn’t, we don’t know what it is,” said Heidi Perryman, executive director of Worth A Dam, a Martinez nonprofit dedicated to protecting and promoting the beavers.

Yesterday that kit from Mt. View Sanitation took a turn for the worse and died. They have no idea why. It’s not unreasonable to think it might be related to our kits’ cause of death. Lory is picking up the little body and taking it to UCD for necropsy this morning. Everyone is heartbroken about this little death, even the reporter I called with the bad news last night.

What is happening to beavers in Martinez?

At the edges of the heartbreak is something else: a stony relief. Maybe the fact that our kits died wasn’t our fault: I’ve been trapped under anvils feeling weighed down with the notion that I’m supposed to protect them and I didn’t. Maybe it wasn’t our dirty creek, our scary homeless, our public feeding. Moorhen Marsh is about 4 miles away and much less trafficked. Maybe it wasn’t anything I could have/should have controlled. Maybe death is gripping our beavers for reasons we can’t understand.  Maybe this baby will give us answers.

But it still sucks.


While we’re discussing pointless tragedies, here’s one I encountered last night on the way home from work. NPR in its infinite wisdom was running a story about some entrepreneurs who are making some money off the feral hog problem in Texas by selling helicopter rides to shoot them from the air. No I’m serious.

Now I don’t want to be a save-everything, or start the first chapter of Worth A Hog, and I believe feral hogs can cause problems. But selling  tickets to an all-you-can-shoot air ride is beyond horrific. And the fact that it was promoted on National Public Radio was outrageous. You can listen to the story here and share your outrage here. Or even better yet directly with the suits here:.

Napa kits wrestle in Tulocay Beaver pond: Rusty Cohn

I know what you’re thinking. Napatopia gets all the breaks. Cute kits growing up and wrestling for photographs. A beautiful photographic lodge anchored to a tree so it won’t wash away. Support from RCD, Flood control AND the county supervisors. A well-attended beaver talk at a local bookstore with ample community support. Yes Napa has it easy in lots of ways.

But here’s one thing Martinez won’t envy.

Freshwater leeches hitch a ride: Hank Miller

These are freshwater leeches in Tulocay creek riding on the back of a pond turtle. Leeches feel the vibration of whatever swims by and float up to catch a meal or a lift. And the hot weather has sent an explosion of them into the streams and lakes of California.

So I guess it’s okay having a little salt water once in a while. Because EWWW.

Personal update. The monster fire burned some firefighters and 86 people’s homes yesterday, but not my parents’. It is  has now burned 65,215 acres and is a  whopping 20% contained.  Still wishing for rain.


Someone notified us about another dead beaver yesterday morning. It was floating by the creek monkey and it was not a kit. Jon haled it out and thought it was Junior or the smaller two year old. I talked to Jennifer from the Bay Area News group while we were getting ready to drive to UCD. But when KGO wanted an interview but I told them things were too hectic. Fortunately the very responsive veterinarian at CDFW worked over time to talk to the media, and print me out the paperwork so we could bring the beaver straight to Davis.

 Beloved Martinez beaver babies turning up dead

Heidi Perryman, executive director of the group Worth a Dam, said the California Department of Fish and Game is examining a dead kit euthanized last month at the Lindsay Wildlife Rehabilitation Hospital in Walnut Creek. State officials have also analyzed a water sample but not yet determined a cause of death.

We didn’t find anything abnormal when looking at the carcass,” said Deana Clifford, a research scientist and wildlife veterinarian with the Department of Fish and Game.

Perryman said the carcass of  yesterdays beaver  appears to be that of either a 35-pound yearling born last year or a 2-year-old. She had hoped the dead animal photographed by Martinez resident Brendon Chapman on Tuesday was the missing fourth kit and not one of the five older beavers who call the creek home. They include an adult male and female, two 2-year olds and the yearling.

The first dead kit was found July 7. Guthrum Purdin, director of veterinary services at the Lindsay hospital, examined a different beaver kit brought in July 8.

 The beaver he saw was practically comatose and taking only occasional gasps of air when it arrived. The veterinarian initially suspected contact with a poisonous substance and euthanized it to shorten its suffering. While kits can be less hardy than adults, young beavers are “pretty durable” animals, Purdin said.

“The deaths were fairly acute and happened quickly and made me suspicious of a toxin exposure,” he said.

State veterinarians have ruled out drought and algae-related toxins, including anatoxin-a, in both the beaver and the creek water, and did not find rabies. Researchers also tested the kit’s brain for high sodium levels after finding a bacteria normally in seawater during a toxicology test. They didn’t find any abnormalities.

Officials have also ruled out tularemia, an infectious disease commonly found in rodents. The disease can cause small die-offs such as the one in Alhambra Creek. It killed a few beavers near Lake Tahoe a few years ago. No other beaver die-offs have been reported in the state so far this year.

“It’s not clear what caused the death of that kit at this point in time,” Clifford said.

In addition to reducing Martinez’s small but beloved beaver population, the die-off holds possibly larger implications.

“(The beavers are) right in our water source, so they tend to be a good marker species,” Purdin said. “If there’s a problem, they can point the way where to look.”

Given how distressing the whole thing is the article came out pretty accurate and informative. I’m so glad Guthrum and Deana were willing to talk to Jennifer too. I was pretty upset but I tried not to babble. (Not to mention that it was one of the worst possible birthday’s ever for poor Jon.) As it is, the article reads as a nice reminder that beavers are in OUR watershed and if something happens to them it might happen to us next.

We went down last night and saw two (mom and dad?) near the footbridge. The dam needed repairs and the level was down a bit. They looked fine, but we are learning that sometimes everything is not the way it appears. I’ll keep you posted on anything we learn. In the meantime I’m hopeful they’ll be more concerned about this recent death and press on with a little more energy so we can get answers.

In the mean time we all need cheering up so here’s a fun article from Oregon.

AR-150819998.jpg&MaxW=600The Beaver Man

We started talking. Five minutes into our conversation, I knew I had met the world’s most passionate spiritual advocate for beavers and walked into one of the best Oregon stories of my life.

His name was James Murphy and he owned a romping tan lab named Marley. He had a house in outer southeast Portland but hated Portland now and rarely went back. He was a wandering man of the North Oregon Coast now, evangelizing for the protection of beavers.

James riffed with the most interesting and unconventional grammar, and I thought it the most beautiful stream-of-conscious speechifying I’d heard in years. Who cares if it was almost impossible to quote him properly? Beavers don’t care about conventional grammar or proper quoting! They just want to be left alone, eat wood, build dams, create marshes and salmon rearing habitat, and play their antediluvian role in the ecology of healthy watersheds. James understood this perfectly and wanted to educate others about the benefits of this maligned animal that was once nearly hunted to extinction because of a fashion trend.

This crusade began a year ago after angels told him to take care of animals. “I’ve known for years about beavers,” said James, “and it was time to start doing something for them. I had to.”

James scouts the local creeks, wetlands and rivers for signs of beaver activity and also imagines their return to places where they are needed to restore damaged watersheds. He’s documenting beavers and beaver dams in some way that doesn’t involve conventional scientific documentation. He’s seeking, finding, observing, and rhapsodizing. James is a “naturalist” of the very old school.

At one point in our conversation, James broke out a little book with a cork-like cover. “It’s my Beaver Book,” he said, handing it to me. He told me he’s collecting names, telephone numbers and email addresses of people who will go to Washington D.C. and lobby for the protection of beavers. I happily signed it and provided my contact information. I was surprised by how many names were in there. He’s been, well, busy as a beaver, and people are responding.

I’m not sure what I love most about this article: James unbridled and infectious enthusiasm for beavers, the authors puzzled fascination with him, the fact that we never met and I don’t know anyone who knows him, or the  painted truck. This is the kind of wildcard that makes any beaver hand more fun to play. I love the idea that he is out looking for local beavers in creeks and spreading the gospel. I love his book with the names of people who are willing to go to Washington.

(But honestly, if the author thinks James is the world’s most “Passionate beaver advocate” – we should really talk.)


Are you sitting down? Because this might come as a big SHOCK. But apparently all those years of ruthlessly hunting beavers affected their behavior. I know, get out! But apparently the scientists are saying what we’ve always known, and it greatly interests the BBC.

Beavers’ activity is still influenced by “ghosts” of long-gone predators, study suggests 

A new study suggests beavers are better adapted to diurnal – or daytime – activity, but switched to coming out at night and twilight to avoid hunter-gatherers.

Past persecution could have influenced beavers’ behaviour down through the generations.  The semi-aquatic rodents’ nocturnal activity pattern could be a persisting effect of the spectre of human hunters, who would have killed the mammals during the day thousands of years ago, according to scientists.

Scientists at the University of Antwerp in Belgium studied camera trap footage in the country’s Flanders region to find out if the the beavers had adapted their activity patterns to a predator-free environment.

But extensive footage revealed the cautious creatures continued to be mainly nocturnal and crepuscular (active at dusk and dawn).

The study, published in the journal Mammalian Biology, suggests this could be the legacy of a long period of persecution that began in the Pleistocene epoch (2.6 million – 11.7 thousand years ago), when hunter-gatherers would have used hand-held weapons and gone out in daytime, before the use of animal traps.

The new study points out beavers’ night-time activity pattern may not be optimal for the species. “First, their eyes are not particularly adapted to seeing in the dark,” Swinnen tells BBC Earth.

 “Second, when beavers would be active during the day which is warmer than the nights, they would lose less energy for thermoregulation, which is beneficial. Third, as a herbivore, their food is always present, so there is no reason to forage mostly during the night.”

Now if this doesn’t sound like news to you, you’re in the right place. I’ve been saying this ever since I read it hypothesized by Hope Ryden in Lily pond, which was written around 40 years ago. And she was informed by the writing of scientists of her time who were writing about earlier writing. The headline on this story should be Everything old is New again! And why on earth WOULDN’T our behavior affect them?

In a decade in Martinez we’ve changed how comfortable one particular family of beavers is around humans. Why wouldn’t 1000 years of aggression do the same for all of them?

It’s important to add that in large rich, safe habitats beavers STILL work in the daytime. Our own Lory watched several in Denali park in Alaska.  The area surely wasn’t without predators, wolf, grizzly and mountain lion to name a few. However their primary threat has always been of the bipedal variety, so they adapted their behavior accordingly. Even the fierce nocturnal wolverine, famously lured by beaver meat, was less threatening then humans. I guess because sometimes wolverines aren’t hungry.

But humans were always greedy.

Glorious photos from beaver friend Sylvie Meller this morning of the new generation in Devon. Enjoy.

Wild beavers growing up fast

The news that England’s only wild colony of beavers had given birth to kits was taken as proof that the creatures are ‘thriving’ by Devon Wildlife Trust (DWT) in June.

Now, pictures taken by photographer Sylvie Meller show the young beavers to be healthy and already feeding on riverbed vegetation.

Sylvie said: “They have grown already quite a bit, but are still tiny compared to their parents.

 “Seeing an adult beaver swimming, only its head would come out of the water. The younger the kits are, the more they are above the water.”

So wonderful and heart-breaking to see. I love the idea that despite all the bruhaha and legal machinations, the beaver family is just marching on. After all the media, and DEFRA, and being trapped and tested, the family is fine. Doing what beavers do. It’s fabulous that Sylvie is there to photograph them. Much better than night cams.

I can’t help think about four particular kits that we will never see grow up. I’m sure you can’t either.
