Citizens deciding how to spend $1.5M in Dixie National Forest

Mark Havnes: Utah News

Cedar City • Beavers could soon be frolicking in the waterways of Dixie National Forest in southwestern Utah.  Beaver transplants were just one project approved by a citizens’ groupcharged with deciding how to use $1.5 million given by the U.S. Department of Agriculture to counties for projects benefiting national forests.

I know it’s the first thing I’d spend money on! Bring back the beavers who can bring back the water who can bring back the fish and the birds and the wildlife that people go to a National Park to enjoy. Apparently a citizen group gets the authority to point these moneys in the needed direction. Part of it goes to relocating beavers and part of it goes to teaching the public how to build flow devices.

Also approved was more than $9,800 for the environmental group Grand Canyon Trust to develop public workshops on how to build flow-control devices so farmers, ranchers and others who depend on irrigation can coexist with the beavers.

With a beaver-ear to the ground I knew that something big was up when last week I heard from two well-known but as-yet-undisclosed beaver defenders that they had been approached about the contract. Moving beavers and managing beavers. Regular readers can probably fill in the names for themselves for the time being, but we’re talking good news for the beavers in Utah, and probably Arizona and Nevada too.

Beavers aren’t the only keystone species to do well in this contract

Another $20,800 will be used to relocate colonies of the threatened Utah prairie dog from Iron County to forest land and $29,500 to fight the threat of plague in existing colonies. Prairie dogs are a perpetual problem for land developers in the area.

Obviously the unwritten maestro in this symphony is the tireless Mary O’Brien of the Grand Canyon Land Trust.  She has clearly made beaver pathways all over Utah and the state is lucky to have her. Rumor is she’s trekking to California this August to learn how Martinez throws a beaver festival, so maybe you can thank her yourself.



My mind is still buzzing with beaver echoes from the dazzling conference. The above is a neat trick Brock introduced me to, called ‘Wordle‘. It analyzes text and produces word clouds based on frequency of use. The more a word shows up the bigger it gets. This is from the ‘our story’ section of the website. Isn’t it beautiful?

I would love to do as good a job as Alex Hiller did reporting as our foreign correspondent on the Lithuanian conference, but for much of the time I was too awestruck to take notes and too excited to write them down. I can’t tell you what it was like to be amongst brilliant minds who knew far more than me about beaver science and advocacy. Here’s a brief summary of some of the presentations I enjoyed the most. They are in order of appearance, because honestly if they were in order of preference, Sherri would probably be first the last and the middle. No offence.

Dennis Martinez started the conference with a discussion of TEK (Traditional Ecological Knowledge). He was very interested in the interface between science and TEK and how true environmental solutions blended the two. He talked about the fact that as science grew more about calculation and less about OBSERVATION everyone lost out. He had remarkable things to say about fire and water, and observed that one of the biggest mistakes the settlers made when they came to America is that they assumed the land was ‘naturally’ that way, and not carefully tended by native peoples.

 

Glynnis Hood has produced such remarkable research that she has become the go-to scientist on beavers. She teaches at the University of Alberta and presented research on a remarkable project documenting the way beaver habitat augments surface water and storage – even without dams.  She showed a map of four isolated ponds that beavers eventually connected with a system of canals, increasing interactivity and flow between ponds. She and her researchers mapped the floor of those ponds and found that beavers dug and carved in the bottom, creating differing zones and augmenting biodiversity. In colder areas beavers dig holes in ponds so that when they come out of the lodge during a freeze they have room to get to the food cache. We were both thrilled to wonder what the bottom of ponds in temperate zones look like. It’s never been studied.

Yet.

Dr. Hood is so famous that I was afraid to talk to her at first. Then I had the weird good fortune to be stranded at the airport with her for 90 minutes waiting for the plane that didn’t take me.  She told me that after the article on our website about her presentation in Lithuania she had wondered ‘who these martinez beavers’ were and what was the story. I made sure she left with a Worth A Dam hat, and plenty of gossip. Since she was interested in beaver canals I told her about the Popular Science article of beavers on Mars and sent it to her. I just got a note back that she loved the picture and will send her paper when its done.

Mary O’Brien has been on my beaver radar since the seminal article in High Country news a few years back. I was excited to find out she was coming and hoping for great things.  I wasn’t disappointed when she presented a work in progress about identifying the economic value of beavers for things like water management and silt trapping. She apparently has decided to do a beaver festival in Utah next year and wanted lots of ideas for involving the community. She decided that she will come to our festival this summer and see for herself.

Sherri gets her own post, but for now I’ll just say that she is a powerful, compassionate, humble speaker with a truly awesome gift for taking a roomful of people intimately into her world of caring for beavers. I am quite certain that not a single person in that conference was unchanged by the experience. Myself included.

The very best part of Mike Callahan‘s presentation was his pragmatic invitation for others to practice his craft. “Flow devices work and anyone can learn to use them” was his message, and his style was to sit down and answer questions with anyone at any time. His excellent images showed me things I had not understood before, and he generously promised that any attendee at the conference could receive a free copy of his DVD. I first wrote Mike on November 4th, 2007 when I was consumed with a great sense of panic. Meeting him after so many years was powerful in ways it will take me a while to process.

Joe Cannon and Amanda Parish are the beaver  division for the Lands Council and  gave a delightful presentation on their beaver relocation and community education program. one idea I particularly enjoyed was the concept of the beaver picnic, where families gathered to learn about the animals, see the habitat and have some fun. Amanda also talked about a delicious children’s activity making ‘candy beaver dams’ using m&m’s, pretzel sticks and frosting to stick it all together.They had a long drive back to Washington but I’m so glad they came! Hopefully at least one of them will make it for the festival this year.

Chris Vennom was the biologist for the Methow beaver project. This bit of genius ecology is using fish hatcheries to house beavers before reintroducing them at carefully selected sites. We swapped beaver stories for much of the conference, I loaned him my mac when his didn’t work, and he was kind enough to repay me with remarkable footage he had take of a beaver underwater in the raceway. Trust me, it’s nothing you’ll forget.

Of course I already knew Brock Dolman and had heard him speak before, but his presentation was truly dynamic. His basic idea is that as global warming escalates the effects in communities are going to be  felt keenest  in the watersheds. Your watershed was your ‘lifeboat’ that would either buffer you or exploit you and it was in your self-interest to take care of it. Brock referenced our historical prevalence  study and provided this excellent graphic which he graciously sent me last night. He also introduced me to a couple from Marin whose land may become the site of the next huge beaver reintroduction study. Stay tuned.

All this could never have been possible without the thoroughly gracious attention of Leonard and Lois Houston, who must have slept 5 hours in four days. They were the first at every event and the last to leave, provided countless introductions and made every single person feel like this particular conference was going to be especially better because they were there.  There were a hundred details they saw to, and they rarely enjoyed the luxury of just sitting and listening to the wonders. It is their vision, wisdom and tenacity that made it all possible

A final mention for  Stanley Petrowski, president of SURCP. He was the ’emcee’ for the entire event, and seemed inexplicably good at everything: ecology, technology and psychology.  He introduced every speaker, kept things running on time and made sure the electronics were agreeable. He greeted me with such enthusiasm I felt like a rock star and any time he needs a vacation I am certain he  can fill in for the finest cruise director in the Bahamas.

Okay, that’s it for now. Don’t think for a moment that I am giving these folks anywhere near the credit they deserve, but I hope this gives you a flavor of what I experienced.  Unfortunately, Michael Pollock had an urgent situation and wasn’t able to attend, so I will have to look forward to meeting him. It will take an enormously long time for me to sort through everything, but in the meantime let me just say that on the way home I was stuck waiting for a shuttle with a man from the Georgia Railroads who said, sagely, “Beavers? Beavers aren’t a problem. They’re easy to take care of. You just shoot them.”

Toto, I don’t think we’re in Kansas anymore.


There are a few things I set aside for reading later – you know truly remarkable affirming news that you can savor at leisure. I would include Summer’s issue of Defenders of Wildlife in that catagory. Particularly the article called “Eager for Beavers” by Heidi Ridgley. If you haven’t read it go do your self a favor and check it out.

“These dams act like speed bumps,” says O’Brien, a botanist and Utah forests program manager for the Arizona-based Grand Canyon Trust. “If water hits one, it wells up over the flood plain, slowing down the water. If that dam crashes and burns in the flood, the water will hit another one like stair steps. The rushing water gets slowed at every turn.”

The generous article stars two of my favorite heroes; Mary O’Brien who I first read about in the Greatest Beaver Story Ever Written, and Sherri Tippie who I talked in a panic to on November 6th, 2007 to see about getting our beavers safely relocated. It lovingly outlines the good that beavers do for the watershed, and talks about our foolish human habit of killing them. It even outlines specific tools to regulate problematic behavior, although I think she got the names reversed.

Solutions to the diverging needs of humans and beavers do abound, though—and they come with clever names: “beaver deceivers” and “castor masters” (Castor being the Latin genus for beaver). Deceivers work by allowing water from a beaver-dammed pond—water that is about to back up and flood over a road, for instance—to escape without the beaver ever hearing it trickle away. “The sound of water running drives beavers nuts,” says O’Brien. “They will try to plug up the leaks.” The pond is kept at the desired level by inserting a pipe in the dam that allows the water to release underwater—right under the beaver’s nose. Castor masters are wire fences with strong posts. They keep beavers from plugging up culverts, which divert water under roads to avoid wash-outs. In this case, beavers hear the water but they can’t get access to the culvert to plug it.

The beaver-savvy folk of Martinez know that what we have in Martinez is a Castor Master, and that culvert defenses are beaver deceivers. Oh well, I’m sure Heidi’s head was filled with lots of ideas and questions at once. She got the idea that beavers help the environment. She got the idea that there were ways to solve problems. And she got the idea that some kinds of rhyming words were involved, which is more than most. I wish she would would have included the generic term ‘flow devices’ so the options can be more generally discussed. If someone reads this article and puts a ‘beaver deceiver’ on a dam they’ll be very disappointed.

This is my favorite part of the article and why Mary is my personal beaver hero.

“People sometimes get excited to tell me they’ve seen a beaver dam,” says O’Brien. “They have no concept that there should be 15 in that one area. We don’t have the cultural memory of how many beaver dams used to fill a stream because the beavers were mostly gone before white people settled here.” Tasha Creek is an exception with its 17 active beaver dams.

Mary was very intrigued this year by the idea of our beaver festival. I got the feeling she might just make the trip and visit some day. In the mean time the author of the article was disappointed that she never got to see any beavers on their trek. Heidi? Do I have some good news for you! The article ends with this adorable acknowledgment.

As a little girl, Senior Editor Heidi Ridgley’s favorite stuffed animal was a beaver she named Thumper.

Because that was a great article and you had a stuffed beaver named Thumper Heidi, you get my thanks and a present. Let  me know when you’re in the Bay Area and I’ll take you to see some beavers that will not disappoint.

Whatever you were planning on reading this morning, put it aside and go check out this fantastic guide to ‘working with beaver’. It was written by Sherri Tippie in conjunction with Mary O’Brien and the Grand Canyon Trust. It has a detailed account of how to protect trees, install beaver deceivers and configure flow devices. It very pragmatically talks about the benefits of beavers and even talks about relocating the ones that just can’t be tolerated. This is the kind of smart, complete guide to dealing with beavers that 200 people attending a certain November 7th, 2007 meeting would have been very grateful for. I put a link to it on the resource section of the website as well.  If the names involved sound familiar, they should. Sherri Tippie is the top beaver relocation expert in the country located in Colorado. I called her the day before that meeting and asked about the potential hazards of relocation and what she’d charge to come out and move ours if we had to take that route. Mary O’brien is the true beaver believer from my favorite ever beaver article “Voyage of the dammed“. Honestly, you just don’t assemble a better beaver team than this. Go read it and the next time we write the city of St. Paul or Juno or Chicago trying to make them think twice about killing beavers, we’ll make sure to send them a copy!

When you’re done marveling at their good work, take a moment to consider ours. My meeting with city staff went amazing yesterday and they are undertaking the installation of the beavers on the sheetpile themselves. Check out this press release for details. It’s perfect timing, because Mom beaver died on a Saturday morning exactly two months ago today. Doesn’t it seem much, much longer? (Maybe I am just much, much older.) Well, soon there will be a reminder of her impact on Alhambra Creek forever, and that greatly heartens me. Thanks Paul Craig for your generous artwork!

If you need a reminder of how things used to be, check out our New York friend Bob Arnebeck’s lovely footage of his new kits with mom. He’s been watching for them all summer anxiously waiting for the launch and they just made an appearance. We know how that is!


Tomorrow begins the “State of the Beaver Conference” in Oregon. I am beyond jealous of the great minds who will gather to talk about the valued relationship between beaver and salmon. Tomorrow at noon will be the Umpqua tribal welcome and conference overview. Then the entire event launched with John Hadidian of HSUS talking about Urban Wildlife. John is the author of “wild neighbors“, a friend of the Martinez Beavers, both our familiar flow-device installers, and generously sent me an autographed copy of his book when I initially wrote him in a panic two years ago. I am eager to have long conversations with him about my idea for a beaver management internship through AmeriCorp that would train half time with both Mike and Skip, taking care of beavers for generations to come. Next is a discussion of the beaver in Europe by Duncan Halley, who it says has a PhD in zoology and a BA in psychology. Coincidence? I think not!

But the star of tomorrow’s opening day will be Michael Pollock of NOAA Northwestern Fisheries talking about the relationship between beavers and salmon. Michael was the reason I was most willing to drive 8 hours to get to the seven feathers casino, and I was delighted when our wikipedia friend nudged him into contacting me. He said that he had family in the area and would be willing to come down at any juncture to give a talk or education program for us. He also said (and this sealed his popularity in my heart forever) that he was once a member of his city council and knew first hand how remarkably pompous and foolish their discussions and decisions could be. Be still my heart! He speaks at 2:45 and I’m guessing will be the recipient of many avid listeners.

Sigh, its no use. I better confess it now. I’m a beaver groupie.

It’s just as well I’m not there. I’d be in the audience with my cigarette lighter raised the whole time. Don’t even get me started talking about Mary O’Brien’s presentation Friday morning. I can’t possibly swoon this early in the morning…
