Sometimes the stars align and a great deal of good news comes to the forefront at once. Sure, days and weeks and sometimes years of hard work went into it. And sure it’s just random now that its finally coming together in sync. There isn’t really a reason for it, except folks want to tie up loose ends before the long weekend of celebrations. But let’s just celebrate the independence of some urban beavers and their founding fathers, shall we?

Beaver sightings reported in Los Gatos Creek in Campbell

Steve Holmes, executive director of the South Bay Clean Creeks Coalition, said he’s seen beavers along the creek stretch in Campbell—in person and on video shot with a camera stationed where they primarily reside.

Back in 2013, Holmes said he saw a small family of beavers in the Guadalupe River near the SAP Center in downtown San Jose. At the time he wasassessing the area for potential creek cleanups.

“We’re down there and looking down from a bridge in the downtown. I looked down and saw a tree had been chewed,” he said. “It looked like someone was chopping it down with an ax. We went down for a closer inspection, and it turned out it was a beaver. Not just one, but a whole family.”

Hurray for beavers in San Jose! And hurray for Steve for being happy about it! We’re not going to say hurray for this reporter because she’s a little lackluster on the subject and doesn’t talk to the right people or do nearly as good a job as the 2013 stories. Just look at this cartoon stick figure of a biologist from fish and game who is SO out of her element!

Terris Kasteen, a biologist with the California Department of Fish and Wildlife, confirmed that beavers were reintroduced into Lexington Reservoir and said some may have been pushed down from the reservoir during the heavy winter rains and subsequent flooding in the area.

“One wandering downstream is not surprising,” she said.

Navroop Jassal, a Santa Clara Valley Water District biologist, said beavers were introduced to the reservoir in the 1990s, and the ones seen in the creek could be from there or possibly from the family of beavers seen in 2013 that Holmes spotted as well.

“The history of beavers in the area isn’t well known,” Jassal said.

The water district monitors certain species in creeks, but does not have an active program for beavers and does not plan to start one, according to Jassal. Instead, it will keep an eye on the fallout from potentially destructive beaver behavior such as fallen and chewed trees or damming. The district would then alert the Department of Fish and Wildlife.

“We would be concerned if it’s damming up areas and backing up the flow of the waterway,” Kasteen said.

Kasteen said a beaver presence in the creek over time could affect waterways and result in trees dying and not regrowing. People are advised to keep their distance from the animals and their habitat.

“More or less stay away from them,” Kasteen said.

I’m sorry but that’s HILARIOUS!!! Not only haven’t you read our articles published in your OWN journal Terris about the history of beaver in coastal rivers in including Campbell, but are ready to depredate them now before they do anything because they’re going to build a dam one day, and you warn folks not to approach them because beavers are like furry hand grenades with the pin pulled out.

They could go OFF at any moment.

Goodness gracious, Terris. I think you get a letter. And guess what else? Now that we’re all talking about URBAN BEAVERS I found out yesterday that our chapter on urban beavers was published in the restoration guidebook 2.0 yesterday. I know you will want to read every word but I’m not yet sure how to just publish that section, so check out the entire document and get ready to spend a great deal of time on chapter 7. I would just post what we wrote but of course the slasher editor fairy altered much (but not ALL) of my beautiful prose, and the original no longer relates entirelt. There is stuff in this chapter I’m not thrilled about – like the word MANAGEMENT for one, and a sentence that is so horrifying I’m still trying to get it shaved off. (Go find it yourself). But the fact that it exists at all is a Martinez miracle, and the sections by Dr. Wohl are breathtaking, the accounting of beaver solutions prodigious, my own humble tweaking of psychology and ecology is pretty darned effective, and the silly sheet is gone, so let’s look on the bright side, shall we?

The very first case study is MARTINEZ whooo whoo and makes us seem pretty dam plucky, and kind of adorable I must say. I do get the feeling that our story has changed the playing field forever, and that’s a pretty sweet legacy.

What are you still doing here? Go read it!

It was the best of beaver times, and it was the worst of beaver times

Traveling to Placer county and preaching the beaver gospel used to be like going to the lions to recommend vegetarianism. But yesterday was more like preaching to the choir. It was a positive, beaver affirmed or beaver-curious group, and our good friends Janet, Jeanette and Damion Ciotti of FWS showed up. They each had wonderful comments and questions, and I made sure Damion connected with the tribal liaison who might just need to be reintroducing some beavers soon and get the federal government to foot the bill for the flow device. I was also excited that Jeanette was interested in an Auburn test site and especially interested when I told her that PGE (where she works) in Auburn had received on of the depredation permits in 2013. Wouldn’t it be good for beavers, and correspondingly good for PGE to be all environmental and generate some press for installing a flow device instead and saving wildlife?

I felt great when we left but I came home to news that our opening band for the festival had dropped out, so I scrambled at a great rate to recover territory I had secured in March. Then before I went to sleep I had the great news that soon-to-be-beaver author Ben Goldfarb will be coming to the festival after all. Which is a relief because I would have been so sad if he missed it. He’s also coming next week to get the story and lay of the land. It should all work out well, fingers crossed.

I see that our good friend Rusty Cohn has his photos proudly displayed in the Napa register today. It’s a great photo essay that you will enjoy on every level – meaning the level where it’s just cool to see beavers and the wildlife they encourage, AND the other more important level where our lovely Napatopia is inches away from screwing with the habitat but good and needs to be reminded that save beaver streams matter.

Photos: Life at Napa’s Beaver Lodge at Tulocay Creek

The Tulocay Creek beaver pond is located next to the Hawthorne Suites Hotel, 314 Soscol Ave., Napa. At the creek, you’ll find river otters, mink, muskrats and herons as well as beavers. Here are some photos of the critters taken by local photographer Rusty Cohn.

I can’t figure out how to embed the entire album here, but you’re just going to have to go see it yourself. Trust me, you don’t want to miss it.

Now, in the middle of all this there’s a wonderful article about urban wildlife published in the SF Gate and all over this morning. The original was published on The Conversation and it is written by Christopher Swan who’s a Professor of Environmental Systems at the University of Maryland. I’m sure ever single reader of this website will have some flat-tailed suggestions for Chris.

Urban nature: What kinds of plants and wildlife flourish in cities?

Biodiversity refers to the variety of all living things on Earth, but people often have very specific ideas of what it means. If you run an online search for images of biodiversity, you are likely to find lots of photos of tropical rainforests and coral reefs.

Those ecosystems are invaluable, but biodiversity also exists in many other places. More than half of the people on Earth live in cities, and that number is growing, so it is especially important to understand how biodiversity patterns occur in our man-made environments.

As an ecologist specializing in urban systems, I spend a lot of time investigating biodiversity in parks, residential areas and abandoned zones in and around the city of Baltimore. My main interests are seeing how urban dwellers invest in biodiversity, which species persist in cities and what kinds of biodiversity can thrive in green spaces.

In spite of the substantial environmental changes that humans have caused in cities, research shows that they still contain many forms of life. And we can develop and maintain habitat to support them.

It is common to assume that few other species remain in disturbed urban environments. But in fact, there are many pockets of biodiversity in and around cities, such as frogs living in stormwater detention ponds and trees in restored streamside forests. Landscapes that people create in and around their homes support many ornamental herbaceous and woody plant species.

Our research group works to understand the relationship between people and urban biodiversity patterns. The most prominent feature of the urban environment is that it is fragmented into many small zones. Human activity creates more patches of smaller size and greater edge lengths between types of habitats than we would expect to see in undisturbed areas.

This benefits species that thrive at edges, like white-tailed deer and nuisance vines, but harms others that require larger interior habitats, such as certain birds. As human activities create a more fragmented environment, it becomes increasingly important to create linkages between natural areas, such as preserved forests, to maintain populations and their biodiversity.

Dr. Swanson! Have I got a story for you! You can bet I’ll be writing the good man just as soon as I finish finding a band to open the Urban wildlife festival that is observing its TENTH year. I love this article and love even more that folks are paying close attention to this topic, because it can only be good news for beavers and humans.

Now yesterday I got some designs from artist Deborah Hocking about our awesome bookmark she is designing very generously for the festival. Look how frickin’ cute this is going to be:

Deborah! That is sooo adorable and perfect for the occasion. I love where your design is going and can’t wait to see the finished project. I know this has been a crazy post of uneven tone. I can’t even see the line from the beginning of my day to the end, it was so full of ups and downs. On the whole I guess there are more ups.

But I still think it’s time to start calming my frazzled nerves by watching this over and over again:

Cue Justin!

Steve Holmes is a creek-loving water steward of the South Bay, and is the tireless and driving force behind friends of Los Gatos creeks and the Clean Creeks Coalition of the South Bay. I met him at our 2010 talk in San Jose, and he has been watching anxiously to see if beavers come back to Las Gatos creek now that things are getting wetter. Last weekend he got his wish and posted this on facebook.

Since 2013, we have seen the return of Beaver into our urban waterways after a 170 year absence. Originally, a family of beaver were located near the Confluence and over time they have spread out across the Guadalupe Watershed. Today after seeing signs of beaver activity and a sighting from one of our Facebook followers, we visited Los Gatos Creek and the beaver was more than happy to swim by and let us catch this video, makes all the sweat equity worth the effort!

Now because of this unexpected siting and some chewing clues Steve felt he might have more the one in the area. He put up a tail cam at the suspected location, and kept close watch.

Last night he sent me this.

I’m sure all you beaver experts will know exactly what I soberly exclaimed when you watch that footage. And what our VP Cheryl Reynolds typed back when I forwarded it to her for confirmation.

Baby Baby Baby, Oh!

So it’s happy vicarious beaver day thursday! You should all do something nice for yourself. Remember to keep your creeks clean, and let’s be happy San Jose has a little beaver family again!

Father’s Day good news

Well what do you know, folks are finally getting around to opening the memo on beaver benefits to trout. Do you think this came as a shock? Now I dearly wish this had been reported in Wisconsin, but hey, North Carolina isn’t bad either.

Beaver ponds actually keep the water cooler, study says

Now scientists and conservationists realize that beavers and the dams they make across streams have a lot of benefits. Most recently a study showed that the big pools of water backed up by beaver dams actually help keep the water cool, and cool water is important to a lot of different types of fish like native trout, steelhead and salmon.

To figure this out, scientists built fake beaver dams and recorded the water temperatures. Although it would seem like a pool of slow-moving water would get warmer, this study found that the water actually was cooler. Why would that be? One reason was there was more and deeper water backed up by the dams. What’s more, the big pools of water seem to help feed water that’s in the ground which also circulates back to the surface, keeping the creeks cool.

Knowing that beavers can play an important role in nature, humans are now putting beavers back in wild places. The Forest Service hauled beavers on horseback into Buffalo Fork Creek, which flows into Yellowstone National Park’s Lamar River. Idaho game biologists dropped parachuted beaver in cages into a remote wilderness area in the 1950s.

Lot’s of generous gifts this week. Starting with a wonderful collection of puppets from Folkmanis which include some delightful hedgehogs, an english badger, a wild-toothed crocodile and a delightfully soft white dog. Thank you a million times over puppet wizards for supporting our beavers since the very, very beginning.

And a wonderful donation from San Francisco author Mary Ellen Hannibal with a fine copy of her recent book where people like us do remarkable things for wildlife.

“For me the most compelling reason to do citizen science is the sixth mass extinction of plants and animals currently underway. In the book I do a lot of reporting and research on this scourge, but contextualize what’s happening within a broad framework. “Extreme citizen science” often focuses on indigenous traditions for caring for the land, and I learn a great deal from the Amah Mutsun tribal band. I take great inspiration from three literary figures who contributed to citizen science—John Steinbeck, Ed Ricketts, and Joseph Campbell. While the hero’s journey as discerned by Campbell needs updating for dealing with today’s global issues, he still provides a model for aggregating individual efforts on behalf of nature to achieve collective impact. That’s the job of the citizen scientist.”

The book is signed. Mary has also been a supporter of the Martinez Beavers since the beginning, and I am grateful that she will continue to encourage citizen science by donating it for the festival.

Of course the beaver problem isn’t extinction, it’s depredation. But I’m sure she’s working on that book next. Thanks Mary!

Finishing the Last of the Mohican’s last night, I thought of my own dad with this quote by the affable, skilled and boyishly cheerful Hawkeye,

“Think of me sometimes when on a lucky trail, and depend on it, boy, whether there be one heaven or two, there is a path in the other world by which honest men may come together again.”

Too many good things for beavers

Some days I just can’t keep up with the hot number of good news stories reported about beavers. I’m already over the moon because Jon picked up the generous puppet donation from Folkmanis yesterday and we received our posters back from the printer. Didn’t this illustration of Alex Riley’s quote, my design and Coyote Brush Studios‘ beautiful artwork turn out extraordinary?

The plan is to sell these at the festival and by mail, although we haven’t settled on a price yet and technically they’ll be thank you gifts for donations, not sales! They are 18 x 24 and would make a wonderful classroom or visitor’s center poster!

As if that wasn’t exciting enough, this morning there’s a fantastic story out of Alberta about the always inspiring Cows and Fish teaming up with the Miistakis institute to undertake a massive survey an beaver education project, to learn how best approach the landowners.

Is Canada’s national animal a boon or a pest?

Beavers: love them, hate them or ambivalent?

A recently launched survey seeks to learn Alberta landowners’ attitudes about one of Canada’s national symbols. Alberta’s Cows and Fish society has partnered with the Miistakis Institute, a non-profit research group associated with Mount Royal University, on a survey to assess landowners’ knowledge and perception about beavers, their habitat and their management.

There are benefits and drawbacks to having beavers on the property, and survey results will be used to further develop education and outreach on the role of beavers in the ecosystem.

“Beavers are a really important keystone species in our ecosystems and they provide some really critical function within our watersheds, and people don’t know a lot of that,”said Miistakis executive director Danah Duke. “We recognize that beavers cause a lot of damage. They take down trees, they flood areas. We recognize that and we recognize that in order for people to be able to coexist with beavers, we need to be able to manage beavers.”

Duke said she suspects many people don’t realize all the benefits beavers provide, such as raising the water table, slowing stream flow, creating habitat for biological diversity and making stopgaps against drought.

“Beaver ponds retain water 50 percent longer than stream sections with no beaver activity, so in times when water is scarce, we find places that have beavers and beaver ponds, water stays on the landscape longer.”

Anyone in Alberta is welcome to take the survey, but the project is aimed at southern Alberta for the moment, said Duke. Organizers are hoping to receive at least 400 responses so that they have statistically significant results.

I am so beyond impressed with the good work Cows and Fish is doing and has been doing since long before Martinez started to play. You can check out the great survey here, I was already their outlier this morning. It’s well done and obviously sneaks in a little education at the same time as it asks questions. Just check out this question which must come as close as a beaver survey can to being a push-poll.

I sure hope during their data analysis they recognize me and wave hello!

A final burst of good news just came from author Ben Goldfarb who is writing the newest book on beavers. He just found out he is the winner of the Aldo Leopold Mi Casita fellowship which means he gets to write his book at Leopold’s home in Taos. It’s a huge honor and beavers and Ben couldn’t deserve it more.

Leopold’s ‘Mi Casita’ residents focus on environment projects

Wolves, beavers and the land ethic are the areas of interest for this year’s participants in the Aldo and Estella Leopold Residency Program, which is now in its fifth year. The residents will spend a month in late summer at the Leopolds’ first home located on U.S. Forest Service land in Tres Piedras.

Ben Goldfarb, a science and environment writer from New Haven, Connecticut, will continue working on a book project about the ecological and hydrological benefits of North American beaver restoration.

In fall 1912, Aldo Leopold, then the newly appointed supervisor of the Carson National Forest, married Estella Luna Otero Bergere, a prominent daughter of Santa Fe. They moved into their new house, called “Mi Casita.”

It was at Mi Casita that Aldo Leopold found his footing as a leader in forestry and conservation. He once described conservation as “the slow and laborious unfolding of a new relationship between people and land.”

The U.S. Forest Service restored the Leopold house in 2007 and has joined with other residency partners to make it available for the Aldo and Estella Leopold Residency Program.

The sponsors of the residency program aimed to promote a transformative “unfolding” by inviting conservation-minded writers, artists, teachers, professionals and practitioners to Mi Casita. Each resident receives a stipend of $500 to help defray travel and living expenses.

Ben says the residence committee was certain Aldo would approve, and we of course agree. He notes that Aldo’s son Luna who wrote so much about fluvial geomorpology never mentioned beavers. But here’s a secret fun fact. Luna was the dissertation chair of Ann Riley who’s recent book on restoring neighborhood streams has a chapter on the Martinez Beavers.

So I think this was all meant to be, don’t you?
