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

croppedgbh When I pause and try to make myself remember that it was MONDAY I found out the artist for the charm activity wouldn’t follow through on his promise and now today it’s SUNDAY and we have a whole new awesome design from Mark Poulin it blows my mind. How adorable is that blue heron? Or the otter?

eebraceletSo kids will be making these bracelets on the day by visiting booths to learn how beavers help these species thrive. They will start at my booth and I’ll give them info and a silicon band to put the buttons onto. And I’ll be ready for them with my special Ecosystem Engineer cap!ecosystem engineerIt’s starting to feel like the festival is REALLY happening. Friday we received a certificate for Lemongrass Bistro, Saturday we got SF Zoo tickets, and today our ad appeared in this issue of Bay Nature. Beautiful placed in a prominent corner next to a stiff coupon that makes the magazine naturally open to that page. Voila!

ad in bnMy favorite part is that the ad will educate as well as promote. Scanning eyes will think, hmm was the west watered by beaver? And minds will be forever changed because that thought was entertained. Not bad for 575.00.

Finally these photos from Rusty Cohn at Tulocay beaver pond in Napa last night just to make the point…

Here’s some fun new research out of Poland on beaver influences in streams.

Beaver ponds’ impact on fluvial processes (Beskid Niski Mts., SE Poland)

-Beavers came back to the Carpathian rivers after an over three hundred year absence.
-Beavers’ dam cascade system changed fluvial erosion, transport and sedimentation.
-Beaver activity changed the headwater valley morphology.
-Beaver damming and ponding affect fluvial systems in montane regions.

Abstract

A. Giriata, Elżbieta Gorczycab, Mateusz Sobuckib,

Beaver (Castor sp.) can change the riverine environment through dam-building and other activities. The European beaver (Castor fiber) was extirpated in Poland by the

nineteenth century, but populations are again present as a result of reintroductions that began in 1974. The goal of this paper is to assess the impact of beaver activity on montane fluvial system development by identifying and analysing changes in channel and valley morphology following expansion of beaver into a 7.5 km-long headwater reach of the upper Wisłoka River in southeast Poland.

 Two types of beaver dams were noted: in-channel dams and valley-wide dams. The primary effect of dams, investigated in an intensively studied 300-m long subreach (Radocyna Pond), was a change in the longitudinal profile from smooth to stepped, a local reduction of the water surface slope, and an increase in the variability of both the thalweg profile and surface water depths. We estimate the current rate of sedimentation in beaver ponds to be about 14 cm per year. A three-stage scheme of fluvial processes in the longitudinal and transverse profile of the river channel is proposed. C. fiber reintroduction may be considered as another important stage of the upper Wisłoka fluvial system development.

Why does this even matter? Because it means beavers are changing the amount of silt that rivers release whether they have the luxury of expanding into a valley meadow, or whether we’re just talking about a series of dams in a narrow channel, like we had in Martinez. And if you’re not sure that matters check how unhappy Lake Tahoe is about filling up with silt, or how much money cities spend on silt removal.

Remember though this is Castor Fiber, so not our kind of beaver. And people will say we need to study more to learn whether this research applies in America, or Canada or other European countries like Germany, or Amsterdam, or to left handed beavers or beavers that work under full moon. But you get the idea.

Of course this comes as no surprise to us, but it gives me another fine opportunity to post a favorite clip.


 

I just found something really fun and had to share. How cool would it be to put Mark Poulin’s bright images on these blocks and invite children to make the arch of a healthy creek themselves. And then challenge them to make that same arch WITHOUT THE KEYSTONE.

arch blocksI found the blocks on a mormon teaching page, (because the use the keystone concept).Then I bought my own set here. I just Mark asked for permission and we can use other images if we need to. If all goes well it could be on the table at Earth day. It would make a dynamic and interactive project that’s really colorful and inviting. You know, Something like this….

CoverBeaver Festival VIII features free wildlife pins by Oakland artist

Keytone species project 2015Worth A Dam is pleased to announce that the first 150 children attending the Beaver Festival on August 1st, 2015 will be able to collect 19 wildlife pins designed by Oakland artist Mark Poulin and purchased with a grant from the CCC Wildlife Commission. The activity will highlight the new wildlife seen in Alhambra Creek since the beavers arrived, and emphasize their role as a Keystone Species. The artist was pleased with the project, saying

“I was so excited to find out that we had beavers in the Bay Area, and a group protecting them, celebrating them,and doing education outreach about them.”

The beloved annual festival will feature live music, beaver tours, children’s activities, and more than 40 ecological booths. Initially a response to the controversy regarding the beavers, the festival has become one of the largest and best attended wildlife events in the state.

This year in particular there’s a lot for beaver-fans to celebrate, as acclaimed wildlife photographer Suzi Eszterhas has been photographing the Martinez beavers for the past two months in preparation for a feature in NWF’s Ranger Rick. This award-winning children’s magazine promises to be perfect place to show case the famous Martinez Beavers.

bioCollageAlthough she has worked with Cheetahs in the Savanna, and Penguins in the Antarctic, Ms. Eszterhas had never seen anything quite like Martinez where she was forced to contend with trains, traffic, homeless, and, she says “one unexpected proposal of marriage.” Despite the urban hazards she was thrilled with her assignment and adds,

“Working with the Martinez beavers has given me a special, up-close view of a mysterious animal that is often shy and elusive. It has been privilege to watch the family live out their fascinating lives right in downtown Martinez! I applaud Worth A Dam and the city of Martinez for their work in being a model for coexistence.”

You can hear all about the visits, bid on her books and more at the silent auction, learn about wildlife or just find about more about the beavers by joining this year’s Annual Festival. Come learn how one city improved its creek by solving a problem humanely. It promises to be a ‘dam’ good time!

I released this yesterday to the media winds. So far only patch has picked it up. Fingers crossed it makes its way around the bay. The festival’s a lot of work whether people attend or not, so it’s more worth it when we’re PACKED.


There is a great article from Ottawa on Michael Runtz, on whose new beaver book “Dam Builders” we are impatiently waiting.

 The tale of the tail: Ottawa beaver expert defends maligned creatures

People say unkind things about beavers: Stupid, destructive, smelly, and destructive again. But Michael Runtz is coming out in defence of Canada’s iconic creature, and the great things it does.

“Beavers ponds dot the landscape everywhere and surely if there hadn’t been beavers . . . we’d be lacking a lot of our so-called small lakes and certainly ponds.

 “And many larger animals would be less common, too. I dare say we’d have fewer moose in Ontario if we didn’t have beavers. (Moose love wetlands and eat water plants that are rich in sodium). And we would probably have fewer wolves.” Wolves often choose beaver meadows — abandoned ponds that drain and produce new meadows — as places to raise pups.

 “If we didn’t have beaver meadows we would probably have fewer Algonquin Park wolf howls,” because that is where wolves gather.

 “When beavers create a pond, trees drown, and dead tress are really important for the ecosystem. They themselves are individual habitats” — first for insects, then woodpeckers, then small animals (flying squirrels, saw-whet owls) that live in woodpecker holes, and finally for turtles and ducks that sit on fallen logs.

 “Every aspect of the pond cycles supports a wealth of different organisms.”

 “Honestly my favourite habitat is a beaver pond,” Runtz said. He suggests it is the best place to introduce young people to nature.

Runtz has been a great defender of beavers, and provided the still photos for Jari Osborne’s beaver documentary that aired on PBS last year. He is also a solid defender of wildlife in general and voluteers with the the Ottawa Carleton Wildlife centre to help raise  awareness. His comments make me realize that it would be an awesome thing to have a active beaver pond within 10 miles of every school in North America! I especially loved this image:

“Go to a beaver pond at daybreak. Its like going to a play at the National Arts Centre. The lights are turned down and the curtain is down and you can’t see what’s there. That’s what a pond before daybreak is like.

 “It’s dark and you hear some motion. You hear sounds. You sense these animals there but can’t see them.

 “And the when dawn breaks, it’s just like the lights going up gradually on a stage or the curtains being slowly raised. It doesn’t come as bright sunlight all of a sudden. It’s a gradual lifting of the darkness. It’s just a compelling natural experience and I just wish we had all our kids exposed to that.”

 Isn’t that beautiful?

Now on to Megan’s slightly less floral letter in beaver defense in Fargo, North Dakota.

Letter: Awful of humans to kill off beavers

There are few things that stun me in this world anymore, but I was completely disgusted with the Fargo Park Board’s decision to wipe out beaver populations along the Red River to “save trees.” This has to be one of the most egregious displays of nonsense veiled as a conservation act.

 “We’ve planted new trees, and then they’re gone,” said Roger Gress, executive director of the parks district. Then stop planting trees, Roger. Last time I checked, the banks of the Red were all set in terms of tree fulfillment. So, you’re going to just murder colonies of beavers every time you feel like too many trees disappear? And you’re going to kill the beavers by either drowning them or trapping them, both gross and inhumane acts.

 It seems like you’re treating the symptom and not the problem. What about beaver relocation? Or simply let the beavers have their trees because they’re an incredibly important part of a river ecosystem and that’s just how nature works. People love to see beavers down by the river. You are all awful human beings for doing this. Shame on you.

Wow. Don’t sugar coat things, Megan. Tell us how you really feel! I only wish she’d mentioned that Roger could EASILY protect the trees with wire instead of relying on murder. But that’s a pretty bold letter. You have to agree. I am very happy when other people defend beavers. It allows me to just sit on the sidelines and beam.

Speaking of beaming, I received word yesterday from the Contra Costa Fish and Wildlife commission that Worth A Dam received our grant for the KEYSTONE wildlife project at this year’s festival! We get the entire award, and I was especially happy to be able to use a little ‘psychology’ in my discussion. After (only?) 8 years the festival finally got support from both the county and the city. Bonus points: they also called my application “thoughtful” which is pretty much the nicest thing anyone could ever say to me. It was thoughtful too. I gave them an acronym. And even a logo!

It’s going to be an awesome festival this year.

Into every life a little rain must fall….

a dam washoutI love this photo, sent by Paul Ramsey of Scotland of the beaver dam on his property washing out during a storm while we were all busy conferencing. Doesn’t look like the cover of a novel you can’t wait to read?

I’m sure that novel would mention that sometimes, after it rains you get things like this:

Capture

I spent yesterday organizing 200 x 20 buttons for the keystone species project at the beaver festival. Mark Poulin and his amazing staff finished the order and shipped it this weekend. Kids can ‘earn’ these at the many different exhibits and get a grand tail to display what they know. Honestly if you live anyhere in California or even the west you had better plan a visit on August 1st, because if your child misses out on this delightful opportunity they will never let you hear the end of it. Mark designed each button for us personally and even borrowed a larger machine to make a slightly bigger beaver! Thank you so much Mark for your creativity and hard work!


After which they can add all those buttons to a burlap beavertail that will eventually look like this:
new tailNow I’m off to settle the account for this magical effort. Let’s hope the K.E.Y.S.T.O.N.E. project grant is funded by our friends at the fish and wildlife commission. Don’t you think it deserves to be?
