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.

Gem state beaver gems

Idaho is a mixed bag ecologically speaking. It is filled to the gills with hunters and trappers and folks who visit the state just because they want to hunt and trap, but it has more than its fair share of really study beaver advocates like Mike Settel brave enough to host an overnight beaver festival with camping and beer in the Beaver dam jam!

Then there are unexpected treasures like this, that seem to pop out of the rich Idaho soil like yellow flowers in the sidewalk.

Beaver ecology to be featured at Southwestern Idaho Birders Association meeting

NAMPA — Dirk Anderson will be featured at the Southwestern Idaho Birders Association’s July meeting to talk about the role of the North American beaver in western ecology.The presentation will look at beaver ecology through the lens of Anderson’s childhood. Growing up in Idaho City, he saw first-hand how beavers influenced the ecology of his back yard.

Anderson will also discuss the history of beavers in North America and how they were the driving force behind western exploration. The presentation will wrap up talking about restoration, conservation and beaver-related issues.

Anderson is the AmeriCorps environmental education instructor at the Boise Urban Garden School. He is a graduate of McCall Outdoor Science School where he received a Master’s of Science in Natural Resources with honors. He also has a bachelor’s degree in biology from Montana Tech of the University of Montana where he played basketball. Anderson is a modern day mountain man, raised in Idaho City, with a passion for the outdoors, art and music.

Mike Settell was stunned to learn about this, because it’s a big, long state and all the beaver players don’t always know what each other is doing. Hopefully he’ll find a way to get a friend to attend Anderson’s lecture, because I would love to know what he has to say. There are pockets of beaver advocacy all the way from Coeure d’Alene to Pocatello and lots of places in between. I just found out about another surprise in the state involving Trumpeter Swans. Seems some lovers of swans have decided that where they nest is so important there should be MORE of it, not less.

Guess where they nest. Go ahead. Guess.

Cygnus buccinator is our largest bird in North Americaso heavy it needs a wide open stretch of water to take off. It is ungainly on land and has short legs like its landlord. These swans nest on beaver (or muskrat lodges) and feed primarily on the rich aquatic plants that surround them. Since it’s the biggest bird we have, it wants the very best place to raise a family and is equipped to defend it handily. (I imagine every type of waterfowl would love to nest on the island of a beaver lodge. No predators to sneak up behind you, no neighbors during the day. But it can fight off anyone else who might want to share.) It’s prime reale state assures that year after year it’s children grow up safe.

Due to it’s size and fortune, it was avidly hunted in the last 200 years, and for a period of time believed to be extinct. Now it’s population has recovered but has suffered because of the damage to wetlands and all those important beavers that maintain them. Especially in Idaho. Swan people are beaver people, and want some wet places that beavers can be safe so that swans will be safe. There has even been a plan to reintroduce beaver so that the swan population could recover, which in a state like Idaho is fairly remarkable.

Trumpeter Swans continue to face a number of threats. In Teton Valley and across the globe, many wetlands have been drained or filled, negatively impacting countless wildlife species, including Trumpeters. In addition, declining beaver populations throughout the Greater Yellowstone region have furthered wetland resource losses. Currently, the Greater Yellowstone Trumpeter Swan nesting population is struggling due to lack of habitat. Biologists are seeing fewer nesting trumpeter swan pairs in our region and even fewer successful nests.

Teton Regional Land Trust has worked with families and other conservation groups over the past 25 years to conserve over 33,000 acres in East Idaho, including 11,000 acres in Teton Valley. The successes of our wetland protection and restoration program, combined with Teton Basin’s strategic location, have created a unique opportunity to reestablish Trumpeter Swan nesting in Teton Valley, and enhance Trumpeter nesting throughout the Greater Yellowstone region.

It’s wonderful to read about good works being done in other places, and fun to find beaver fans where you never even thought to look. You would think, that between the swan people, the frog people, and the salmon people beavers would stand a chance in this crazy concrete-driven world. But the deck is pretty much stacked against them. Turns out we really, really like culverts.

And we really hate the things that plug them. Go figure.

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!

I didn’t find Neal Maine on youtube, but I did find this recently uploaded. It’s a fun watch with lots of pointed credit for beavers.

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:
