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

Month: December 2023


Deep with the first dead lies London’s daughter,
Robed in the long friends,
The grains beyond age, the dark veins of her mother,
Secret by the unmourning water
Of the riding Thames.
After the first death, there is no other.

A Refusal to Mourn the Death, by Fire, of a Child in London Dylan Thomas

A beaver that was recolonizing the Matadero Creek in Palo Alto and was being treated for an unknown ailment has died, Ashley Kinney, hospital manager at the Wildlife Center of Silicon Valley, said on Tuesday. The female beaver will be taken to a state laboratory for necropsy to determine her cause of death and underlying conditions. Kinney said the wildlife center was still waiting for diagnostic results before the beaver died. Staff found her deceased after arriving at the center on Monday morning.

The famous Palo Alto beaver didn’t make it. I found out yesterday from Bill and Rick who were both pretty saddened. I was worried about that because of the long track record we have of beavers being taken to rehab and dying. I think by the time a beaver is unwell enough to lay there and let herself be scooped up she is pretty far gone.

Of course it reminded me of this, and I sent the post to the men in case they were worried about how the offspring would cope. There are no orphans among beavers.

Adoption June 27, 2010

t night we went anxiously to see what happened with our newly “orphaned” kits. The day’s loss was heavy on our hearts but we were worried that our kits could face a tough road ahead. I had a long conversation with Sharon Brown of Beavers: Wetlands and Wildlife about whether our kits were old enough to stop nursing. She assured me they were. And then we watched and waited.

The biyearling (one of our three kits from 2008) has been hanging around the pond more than usual. S/he used to head downstream for long forages on his own. The last few days s/he has been much closer to home and there have been several protective tail slaps seen. This is a sleek, handsome, nearly adult beaver. Last night they approached the area where the kit was feeding and we were hopeful for a full on acceptance of him or her as parent. It didn’t happen at first.


The biyearling brought branches from the dam into the lodge. Then went up on his own and gathered some from the area of the felled tree and brought those in as well, like a suitor bearing daisies to win the girl. He or she swam around protectively and made their presence known. Then we saw this. I’m leaving the audio in on purpose so you can hear the kit whining for care and attention. I wish the sounds of human weeping weren’t also audible, but it was a long day and the whole scene was heart-wrenching.

I realized at this moment that our kits have been “acting older” than they are because of mom’s health. Their foraging and being out on their own was merely an attempt to get food that they couldn’t receive with her. With mom there, even sick, the yearling felt less responsibility to step up and take care of them. Now that mom was gone, our babies were acting like babies again. And our yearling was becoming a parent.

We haven’t heart adult-directed whining for a week or more. Or seen a beaver back-ride since that first film of baby and mom. It’s as if our kits were given a fresh start last night. They get to be cared for and babied. And their dependency activated remarkable parenting in the yearling. It was truly lovely to see.

The light was fading fast, but in the above you should dimly be able to see two kits perched on the biyearlings back and carried into the lodge. Our babies can be babies again, and  in the span of 24 hours our biyearling has become a remarkable parent. Surely some of this process is instinctual, activated by the need of the kits and the corresponding need to nurture. But some of this parenting must be learned, because our biyearling had the very best possible teacher on how to be a mom.

The teacher herself would be so proud.


I realized when I found myself tearing up again that Dylan Thomas had been wrong:

After the first death there are many others.


Yesterday I stumbled across the newly formed Western Beaver Cooperative, brain child of Reese Mercer formerly of Beaver Works and now leading the way with this volunteer based effort. The website is full of good advice and nice graphics that might come in handy. I don’t know the backstory on why one cooperative suddenly ends and another begins, but working with an all volunteer army is a tough gig and sometimes there are human obstacles that cannot be over come.

I especially liked this graphic…

And this awesome collection of webcam captured visits to a beaver pond during the third year of drought, Watch the whole thing because I especially like the field mice and the night jar.

More beavers without hypothermia:


Palo Alto is riding on the beaver learning curve today. An adult beaver was reported sleeping in a pile of leaves out of the water in Matadero creek on Friday, and brought by an animal control officer to Wildlife Care in Silicon Valley.

Rare Palo Alto beaver getting treatment in Wildlife Center

Female semi-aquatic rodent was found lethargic and hypothermic in a concrete channel of Matadero Creek

A beaver that is recolonizing the Matadero Creek in Palo Alto was taken to the Wildlife Center of Silicon Valley on Wednesday after being spotted immobile in a pile of leaves, officials said.

Palo Alto Animal Control Supervisor Cody Macartney said a pedestrian found the adult female beaver in a concrete channel of lower Matadero Creek near the former Fry’s Electronics site, and reported it to Palo Alto Animal Control. The animal, who likely made her way to the channel from the wetlands, wasn’t moving and looked as though she didn’t feel well, Macartney said.

Macartney took a photo of the beaver and sent it to the wildlife center, which confirmed that its behavior wasn’t normal.

“She was so unaware of my presence that it wasn’t too hard to capture her,” Macartney said, but he did have a little trouble getting the beaver into a carrier and into his truck –– given that the animal weighed more than 60 pounds. He transported her to the wildlife center, where she was found to be extremely lethargic and hypothermic, Ashley Kinney, the wildlife center’s hospital manager, said.

Kinney said the wildlife center kept the beaver warm in an insulated enclosure and gave her fluids, antibiotics and vitamins.

Heavens! If that beaver was hypothermic from the terrors of sleeping outside the lodge in SAN JOSE IN WINTER I will eat a bug. Beavers walk outside in the tundra and don’t have get hypothermic.  That portion of the creek is all concreted so there’s no way make a bank hole. And from that beavers point of view the officer picked her up in the middle of the night. How responsive are you at 3 am woken from a sleep? Without your glasses?

“As of this morning she is eating and walking around,” Kinney said on Friday, Dec. 1.

Officials don’t know the beaver’s age, but did say she is a large animal, weighing 63 pounds.

“She’s a big girl,” Kinney said, a sign that the semi-aquatic animal is finding an adequate food source.

The wildlife center is currently working on getting a fecal sample from the beaver to check for internal parasites and get a better diagnosis of why she became ill. The beaver’s coat, which is usually oily to help insulate her in the water, was also dry and might be a reason she became hypothermic in the chilly creek and wetlands, Kinney said.

Once she is stabilized, the beaver will be transported to a specialized center in Sonoma where she will continue her rehabilitation until she eventually returns to the channel and wetlands.

What? You say the beaver sleeping outside the water had a dry coat? And you haven’t gotten a stool sample yet but you’ve give her a nice bed of straw to lay down in? You do know she needs water to poop right? And to be stimulated to groom?  I mean I know silicon valley isn’t exactly beaver central but I’m sure you have access to the internet right? I believe your people invented it.

Now I suppose that beaver could have been sick with something not described in the article but I’m not ready to panic over her imminent demise anytime soon. Here in Martinez we’ve seen our share of beaver sickness, but I’m not reading anything that alarms me yet. Maybe Chill out for now? It’s a beaver.

As long as its not crossing the street it will probably be okay.


The World Wildlife Fund is a glossy high powered nonprofit that saves high profile animals like Pandas and Penguins. In the past couple of years they’ve become interested in beavers, and there was some work they were doing in PEI to help salmon navigate around beaver dams. (!!) I am a traditionalist when it comes to beavers. I generally think that if there was an easier way to prevent beavers building up dam they would have found it by now.

But what do I know?

To trap or not to trap: Dam good options for coexistence

JACKSON, Wyo. — Wyoming Wetlands Society (WWS) and the U.S. Forest Service (USFS) are currently working to support coexistence with beavers as a longer term solution to trapping. This past month, the organizations collaborated on a dam notch exclosure fence on Dog Creek in the Snake River Canyon in an effort to preserve beaver presence and wetland creation while protecting the area’s infrastructure.

Cody Pitz, wildlife biologist and beaver restoration program coordinator with WWS, tells Buckrail the project is intended to reduce beaver conflict by allowing the beavers to remain in the landscape while mitigating for road flooding. He says a dam notch exclosure fence (pictured here) is a more efficient and cost-friendly option to a pond leveler, and maintains water levels by allowing water to freely flow through a fenced notch in the dam.

“This is new to the Bridger-Teton, so we’re figuring out things as we go,” Ashley Egan, Bridger-Teton National Forest wildlife biologist, shares with Buckrail. “This project was a perfect success example. It’s showing the community, our visitors and other folks who do land management in the GYE that there are tools out there for beaver coexistence.”

Pitz says he’s optimistic that more people are coming around to the idea that beavers are a necessary part of the ecosystem. While beavers can have different impacts in an area, he says the dam notch exclosure fence is just one of a number of different approaches that can be considered before live-trapping and relocating the keystone species.

Hmm. Hmm. Hmmm. I guess I could be wrong here but I generally think if I was a beaver and suddenly I couldn’t fix the dam that was protecting my house anymore I would just build another one. Wouldn’t you? I mean the materials are right there and the labor is free…

“I’m optimistic that we can get more onboard with coexisting with beavers,” Pitz tells Buckrail. “As more and more people understand the benefits of beavers, we can get there.”

Egan echoes this sentiment with the USFS. According to her, finding a balance between appreciating the benefits of beavers to riparian and wetland ecologies and maintaining infrastructure lies in utilizing beaver engineering skills as a management tool. The BTNF will re-evaluate the dam notch exclusion fence’s success in the springtime, and are committed to investing in continued alternative solutions.

“We’re not just going to be giving up,” Egan says. “We want to showcase that this can work. We don’t need to trap beaver out of the landscape just because there’s a road there. WWS has contributed a ton of expertise, and we’re hoping that there’s more coming down the pipe.”

Notch fence? What do I know? Maybe it’s about the audience. Maybe he figures that the odds of a NOTCH FENCE working are slightly higher than the odds of talking any rancher in Wyoming to coexist with beaver in the first place.  If that’s the case, then good look to you.
