Yesterday the bookmarks arrived and they are every BIT as cute as you might imagine. Jon ran some over to our buddies at Parks and Recreation and the oohed and passed them around with glee. Yesterday was also very exciting because I suddenly realized I didn’t have the contract for the solar panel, and fell into a state of panic that I hadn’t ordered it this year. What if all the bands were lined up and the sound guy was there and there was NO SOUND! I called them in alarm only to find out that every single representative was at a big meeting and they would call me on monday. I must have sounded so truly forlorn that they made Ryan call me back from the meeting – which I found out was IN HAWAII by the way – YES they would help me, not a problem, but please let the man go back to his hawaii meeting so he can spend the last part of his last weekend at the beach.

Whew.

Good lord. That was close. I know I spoke to someone about something way back in March, but I also know nothing is firm without a contract and they need us to show our event insurance will cover their panel and these things take time. Three weeks should do it. So that’s good.

Meanwhile our friend Kent Woodruff at Methow was being rewarded by a lovely, slick magazine profile in the outdoor clothing store of Filson’s. Even though the head quarters is in Seattle they have a store in San Francisco so I have NO idea why they aren’t donating to the beaver festival, but good for Ken (again), it’s still lovely to share.

Region 6: Planting Beavers, Raising Waters

Beaver ponds store a lot of water. Millions of gallons. And scientists are now realizing that reintroducing the animals to struggling streams is a way to buck a drying trend. This Filson Life is part of Filson’s celebration of the Forest Service and the people of the Pacific Northwest Region of the USFS, Region 6.
As the Northwest gets less snow, Kent Woodruff says it needs more beavers.

Less snow means less rainfall. Less rainfall means less water for farms and streams – which leads to a decrease in spawning ground and shelter for salmon. Beavers dam streams and streams flood their floodplains, which produces more trees for more dams and provides millions of gallons of water for everything in the vicinity. It even provides shade for salmon.

“One of the things we know is that beavers improve streams,” says Woodruff, a beaver biologist with the Forest Service. “Beavers make things better by adding complexity to streams to enhance everything that needs to happen out there.”

For the past ten years Woodruff has been the driving force behind the Methow Beaver Project, a partnership that relocates problem beavers – those that have dammed up irrigation ditches or felled high-value fruit trees – from private land to mountain streams in the National Forest surrounding Central Washington’s Methow Valley.

“We’re in a very water-limited situation in the Methow Valley,” he says. “So we do this balancing act between the towns, the rural folks, the agriculturalists, and the fish. To find a natural solution in beavers for water storage and temperature moderation, which are critical limiting factors to endangered salmon, is really exciting to what we do.”

After trapping a problem beaver, Woodruff temporarily keeps it at an old fish hatchery that he’s set up with beaver homes. He’s found that relocating beavers is best done with male-female pairs, and he waits until he traps a beaver of the opposite sex before pairing the two at the fish hatchery. He then transplants the pair—with a bundle of sticks and willow switches they’ve been chewing at the hatchery—to a suitable, beaver-free stream in the forest.

“We’ve found that a male-female pair is a lot more sticky than just a lone beaver,” he says. “Two of them are more likely to stay where we put them than just one.”

Half a dozen universities are making plans to use his beaver restoration work as laboratories to answer questions about the role of wetlands in the larger ecosystem. How much carbon does a large beaver complex store? How do beaver ponds contribute to the insect life of a river? How many gallons of water are stored in the spongy soil surrounding a wetland? Interns, graduate students, and Ph.D. candidates from colleges and universities around the Northwest will show up in the Methow Valley this summer to work toward answering those questions.

Woodruff and Johnson estimate that their pro-beaver message reached 2.8 million people in 2015. The benefits of beavers, Woodruff says, are becoming more widely recognized. Biologists in Canada, Mexico, and Europe are interested in the work coming out of the Methow Valley and elsewhere around the region.

“California is very interested in modernizing its approach to beavers,” Woodruff says.

“Washington state is beginning to take similar steps. We’re talking to people in Britain where beavers have been extinct for 600 years, and now in the past ten years they have them in five different places. Idaho has a fledgling relocation program, too. It feels to me like we are just getting started learning where beavers could help.”

Nice review! Wonderful to see beaver benefits emphasized. This is a rugged outdoor clothing profile so they chose the strapping young Ph.D. candidate for the photo, which is foolish because Ken’s very handsome and there are way more mature shoppers than young ones, but never mind. It’s a nice spread with a good focus on salmon and water and I’m very grateful about that. Of course I’m very impatient with ANY article that mentions problem beavers without talking about beaver solutions.

But still.

I confess I was alarmed reading that in 2015 reached their message reached 2.8 million people, because how on earth is that even possible? This meager website gets 10,000 hits a week, and over 10 years that’s maybe 1 million, but how are they so much more visible than we are? What’s WRONG with us? But then I though they maybe meant through Sarah’s great film, which was wonderful and really allowed a lot of people very quickly to learn the story of why beavers matter. And they have more supporting players (NGO’s and GO’s) than god. And plus, people are always happier thinking they’re doing good for the environment when they get rid of beavers than when someone tells them to keep them.

But I admit it. I had beaver envy.

SNF: Every Beaver Everywhere

I try to stay beaver-centric on this website, but once in a great while an article about general ecology grabs and holds my attention so much that I can’t entirely escape. Besides, this entire article might as be about beavers anyway. Every Single Beaver Everywhere.

The big ecological roles of small natural features

Ecologists and conservationists have long recognized that keystone species have major ecological importance disproportionate to their abundance or size. Think beavers, sea stars and prairie dogs—species that >Similarly across landscapes, the keystone concept of disproportionate importance extends to other ecological elements, such as salt marshes in estuaries. Now an international group of researchers is exploring the disproportionate ecological importance of small natural features—unique environmental elements that provide significant ecological and economic impacts.

Desert springs. Caves harboring bat colonies. Rocky outcrops. Strips of natural vegetation edging agricultural fields. Riparian zones. Small coral heads. Tiny islands. Large old trees.

These small natural features are often overlooked, relatively vulnerable yet environmentally mighty in their ecosystem. They also are at the opposite end of the spatial scale from the Earth’s large conservation superstars—the Serengeti, Yellowstone and the Great Barrier Reef.

Or hey, maybe an unexpected beaver pond in an city stream? Sustaining unique habitat even in the middle of town?

Small natural features have big ecological roles, according to the 37 researchers from 11 countries writing in a Special Issue of “Biological Conservation.” Sometimes they can provide resources that limit key populations or processes that influence a much larger area. Sometimes they support unusual diversity, abundance or productivity.

They also are small enough to efficiently maintain or restore, while traditional land-use activities continue in close proximity, such as forestry, fishing and grazing.

“Small natural features are an example of what can be termed ‘The Frodo Effect,'” writes Malcolm Hunter, University of Maine professor of wildlife resources and Libra Professor of Conservation Biology, in the journal introduction.

“In the ‘Lord of the Rings,’ the small and unassuming hobbit Frodo has more strength than any of his larger peers and saves Middle Earth with his brave actions,” says Hunter. “Gandalf and the rest of the fellowship of the ring go to great ends to protect him, because they know this.”

And you thought that only techs could be geeks. Apparently what Star Wars is to silicon valley, Tolkein is to biologists. They love thems some Frodo. We’ll let them have their fun, but that’s silly, because it’s not even the passage I would have chosen for this significant contribution played by very small things.

“For you little gardener and lover of trees,’ she said to Sam, ‘I have only a small gift.’ She put into his hand a little box of plain grey wood, unadorned save for a single silver rune upon the lid… ‘In this box there is earth from my orchard, and such blessing as Galadriel has still to bestow is upon it. It will not keep you on your road, nor defend you against any peril; but if you keep it and see your home again at last, then perhaps it may reward you. Though you should find all barren and laid waste, there will be few gardens in Middle-earth that will bloom like your garden, if you sprinkle this earth there. Then you may remember Galadriel, and catch a glimpse far off of Lórien….”

Isn’t that much better? Now let’s get back to the subject of this article. Small natural features (SNF) like a big oak tree, or a small rock outcropping, or even a drowned stump in the river, are often the nexus around which a collection of wildlife is gathered. And if it wasn’t there, the collection wouldn’t be either. More than this, the researchers argue that actually saving that frog pond or small stand of trees beside the field might have as important an impact as a large scale restoration project that costs hundreds of thousands more dollars.

Will someone PLEASE argue this case in court to save a beaver pond in the next 6 months?

Every time an individual city or landowner makes the decision NOT to rip out a beaver dam, they are allowing one of these important SNF’s to exist. And every time they trap a beaver they are destroying one. Don’t believe me? Here’s some of the biodiversity our friend Rusty Cohn photographed at the tulocay beaver pond between a hotel and a car dealership in downtown Napa last week.

Beavers welcomed in Maryland park

It’s nice to see beavers greeted in Maryland with anything other than alarm, but here’s proof that it sometimes occurs.

Off the Beaten Path: Busy beavers create ponds near Ritchie Highway in Severna Park

Along Cattail Creek large trees are being cut down near the water’s edge and used for development nearby. The trees have been felled by the teeth of beavers, and the development is two beaver dams, built inside Cattail Creek near Ritchie Highway in Severna Park.

Over the past two years, the beavers’ work has transformed the area from an emergent wetland to that of a flooded wetland, said Magothy River Association President Paul Spadaro. The beavers have created nothing short of ponds and a shoreline in the area.

Interested residents can check out the beavers’ craftsmanship for themselves — the site is accessible by public property, the county-owned Cattail Creek Natural Area.

The first dam built by the beavers is close to Ritchie Highway where it passes over Cattail Creek. The dam is at least three feet tall.

Farther upstream is a second dam, which Spadaro said has been built recently. He noticed a lot of activity this winter. The beavers did not apply for construction permits, so a precise construction date wasn’t available.

They’re active from dusk to dawn, so the best shot at seeing a beaver is likely in the early morning. That’s exactly what Magothy River Association intern Campbell Jones and volunteer Charles Germain did Tuesday.

The pair caught the critters in action Tuesday around 5 a.m. and made a video available on YouTube and posted on the Magothy River Association’s Facebook page.

Urban Beaver Bonanza

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!

Beaver credit where credit is due

Ask and ye shall receive, that’s the way it works here at Beaver Central. Yesterday I posted the confusing photo of what appeared to be a beaver with two colors of teeth and friend Lisa Hodge, a wildlife rehabber who has raised beavers, commented that the white wasn’t teeth but a tongue (as Jon believed). She notes if you zoom in you can see a faint hint of orange upper teeth above that.

So mystery solved I guess, although why that particular beaver was sticking out his tongue will remain a question!

Maybe calling ourselves beaver central gives the wrong impression. On Wednesday I got an email from a magazine author in Canada bemoaning the allegations of beaver population explosion the region of Manitoba and wondering if I might I know any local experts to consult? So I spent an hour introducing her to the major players in her home country. And then I received a query from the Quebec Zoo saying they had just received an orphan beaver and how should they care for it?

Do you people do ANY of your own work, I thought?

Of course I sent our orphan care page with plenty of links. And made sure to mention that if they didn’t want more orphans they should stop killing the parents. But my words are a drop in the bucket, I’m sure.

Meanwhile we’ve been busily getting ready for all things festival. I finally have the map in place and I updated the festival page so it links to every exhibitor. Youcan check it out by clicking on the flyer on either margin.

We’ve also been finalizing the magnetic beaver pond, which kids can arrange however they like. We got the idea from the fun board at an International Bird Rescue display where we saw many children happily rearranging the magnets again and again. IBR used a flat metal display but I thought, hey we have that extra metal beaver made for us by Paul Craig when mom beaver died, why not use her? Hopefully it will work as a fun activity for kids to learn about the inhabitants of a beaver pond.

Speaking of inhabitants, there’s a nice little article about beaver and wood ducks from Seaside Oregon where the beaver tales very successful art exhibit has concluded.

Just in from Neal Maine. Lucky 13.

Wood Ducks live in wooded swamps, where they nest in holes in trees or in nest boxes put up near or over water. They are equipped with strong claws that can grip bark and perch on branches. These cavities are typically places where a branch has broken off and the tree’s heartwood has subsequently rotted. Wood Ducks cannot make their own cavities. https://www.allaboutbirds.org/guide/Wood_Duck/lifehistory

Beavers are responsible for creating the wetlands that the wood ducks call home. Beavers and wood ducks go hand in hand. Woodies are fond of waters with plenty of wooded cover — hence the name — and a new-built beaver pond offers habitat that attracts and keeps wood ducks in the vicinity.

Nice job giving credit where credit is due. I wish someone had filmed Neal’s talk on beavers because I would have liked to see it. Our local friend Brian Murphy has been watching over wood ducks and putting up boxes in walnut creek for a decade. After 10 years of labor he finally got a photo of the babies emerging and sent it excitedly last night. Sometimes good works take time. And sometimes very good works takes a lot of time.

Thanks Brian for your hard work and great photo!
