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

Tag: Nick Bouwes


This was a fun report yesterday, Today it is being picked up by all the science sites around the internet and even Yahoo news! Never mind that it’s not strictly accurate, I mean beavers might be moved in Utah but they still aren’t being moved in California. It’s a lofty goal to which we aspire. Right?


Forrest Gump was wrong. Life is not at all like a box of chocolates.

There are great, nouget filled days to be sure with little sea salt and almond sprinkles on top. But the saying implies that even the rotten days are still sugary sweet, And that’s just not true. Life is more like an Easter basket filled with assorted chocolates and also dotted with hang grenades and root canals.

Yesterday we tasted all of them.

The final signup numbers for the conference look really good. Better than expected even, with a new registration from Kansas fish and wildlife of all places. We stand at nearly 900 registrations, and 600 of them are from the golden state, which is everything I can hope for,

But then we saw that the scrappy newly dam built by an anonymous beaver in the park behind my house had been ripped out by city staff. Totally. You can still see the footprints where they hiked down the hill to do the deed. It feels so pointless. I almost wish I didn’t care at all because then I’d never notice and feel like this,

All the wood and mud and stone gone. The crutches and booze bottle gone. All the fresh grass on the bank dying because of the missing water and their rotten feet stomping down to the bank to wield the rake. Any hope Martinez has of being in National Geographic gone – don’t ask. Sometimes I really hate city staff.

But if the beaver is feeling like sticking around he might try again. And we also got this yesterday, which is as good of good news as your heart ever wanted to hear. If you never even watch videos on this website change your policy today because this is GOOD. And it doesn’t make up for the hand grenade and the root canal but it comes really dam close.

So close and yet so far. Yesterday’s magically returned website didn’t disappear into thin air like I worried it would. But it did eventually grow a crippling handicap that I’ll still have to wrestle with today.

If you want to see what it is, try clicking on any “Page” in the drop down menus.

The problem with inheriting a large website of patches is that fixing one part often breaks the other part! I’m sure we’ll get there. It will just require another robust dose of snappy hold music.

But enough shop-talk, lets go to Oregon and talk about BDA’s.

Mimicking nature’s dam builders

Now, in an about-face that bodes well for beavers, stream restoration professionals are turning to small wooden impoundments as a way to improve fish habitat and riparian areas across the West. Made of pounded posts and woven willow whips, these beaver dam analogs are considerably cheaper than other restoration techniques.

Even if BDAs don’t attract beavers to an area, they mimic the action of natural beaver dams — slowing stream flow, improving groundwater connectivity to the surrounding area and building up sediment to improve riparian areas. Juvenile fish can swim through gaps in BDAs, and the minimum fish-jumping height for older fish can be achieved by installing multiple BDAs.

Beaver dam analogs can also help reduce stream water temperature, according to Stephen Bennett, an adjunct professor in watershed sciences at Utah State University. BDAs can increase groundwater connectivity through annual spring flooding and by the hydraulic action of the standing water behind the dams.

Hey! I got an idea about bring back beaver benefits. Just stop killing them! How’s that for a novel idea?

Getting the word out on beaver dam analogs was the goal of a workshop held in Grant County July 24-26. Thirty-five stream restoration professionals attended talks at Grant County Regional Airport and field trips to Murderers Creek, Camp Creek and Bear Creek in the Malheur National Forest.

Attendees included people from watershed councils, soil and water conservation districts, federal and state agencies, the Confederated Tribes of Warm Springs and private contractors.

The purpose of the workshop was not just instructing people on how to build beaver dam analogs or persuading them to use the technique, but also to release new information on what’s been accomplished, said Elise Delgado, project manager for the South Fork John Day Watershed Council.

“Not everyone will leave a believer,” she said.

The workshop was sponsored by the John Day Basin Partnership, which represents groups from Prairie City to the Columbia River. Herb Winters, a project manager at the Gilliam Soil and Water Conservation District, sits on the partnership’s steering committee.

Well gosh. If you can get people excited about beaver dams by letting them build them themselves I guess its a good thing. But you do know beavers have their own ideas, right? They might happily use that BDA and then add three more upstream when you didn’t plan to have a beaver dam at all.  You know how it is when you bring in a designer. They always have their own plans for the space.

At least Nick has the right idea.

Nick Bouwes, a professor at the College of Natural Resources at Utah State University, advised workshop members to be efficient in how they build BDAs because a project might require a lot of them. He said he prefers a messy one, the messier the better — if a post goes in crooked because of rocks, let it be, he said.

Bouwes was a leader in the largest beaver dam analog project in the United States, on Bridge Creek near Mitchell, where a powerful stream had gouged a 6- to 10-foot-deep incision. About 2.5 miles was treated to improve habitat for steelhead starting in 2005.

Bouwes and his team built 121 BDAs from 2009 to 2012. By 2013, beavers had fortified 60 of the BDAs and built 115 new dams. The stream bed gradually filled with sediment and rose back to the top of the trench, and the submerged area tripled.

Monitoring showed Bridge Creek produced nearly three times as much fish as a nearby control stream, and water-temperature spiking eased. The results made Bridge Creek the poster child for BDA projects, drawing international attention and documentary filmmakers.

As it happens I’ll be using Nick’s video tomorrow in my presentation at Sulpher Creek Nature center, which makes it a very good time to re-share.


Maybe I was a little bit right about late October. Yesterday we got some wonderful beaver articles. I’ll save the delight from Cows and Fish in Alberta because we already know about them. This was a bigger surprise from Idaho of all places!

captureBeaver bring back Birch Creek watershed

Necia P. Seamons

Two beaver families are making homes in Birch Creek. It may not seem to be earth-shattering news to some people, but the tale of their return to the creek reveals several powerful concepts. The critters represent a decade of effort and many more years of personal growth on the part of one dedicated Mink Creeker, and the benefits his efforts will have for people that will never know him.

Twenty-one years ago, Jay Wilde returned to the home he had been raised in as a child– the last house before the Forest Service border on Birch Creek. He always had a dream to raise and sell cattle, but life had taken him away from his hometown and his dream. 

“I had to do something to get the stream flowing so the cattle could utilize the feed the land was producing,” he said.

Now you might have guessed already how this ends. But read on anyway and follow his misguided effort first to “Rip out all the cottonwood trees because they were too thirsty” and eventually go to Utah state to ask their advice. The article doesn’t say but I confirmed this morning that lucky for all of us he happened to connect with Joe Wheaton and Nick Bouwes, who suggested the answer might just be a little more flat-tailed than he suspected.

But something was bothering him. He remembered from time he spent in the hills as a boy in the ‘50s that water should be running year round from Birch Crabsenceeek. 

“There were all sorts of plants and animals that depends on that stream having water in it. …We just can’t throw our hands in the air and walk away. That’s not fair to all of the life that depends on that water,” he thought.

“One morning in 2006 I was sitting at my kitchen table at 4:30 a.m., waiting for the caffeine from that first cup of coffee to kick in when it dawned on me… there was no beaver activity in the drainage,” he wrote.

“My family and friends spent much time fishing, swimming, and watching the activity in the beaver ponds. Now in 2006, those ponds are all gone and there’s no sign of the rodents that built and maintained them. Could it be that the absence of those critters with their ponds and harvesting the woody species in the riparian areas was contributing to the demise of our stream?” he wondered.

Ooh ooh I know! Call on me! Now shhh Heidi, sometimes people need to work out answers for themselves. Jay was on the right track and he just needed a little nudge to get there.

The questions fueled further research and Wilde contacted anyone he could find with knowledge of beaver and their impact on an area. What he discovered was that when beaver dam up an area, the water table around the dam is raised significantly. The ground acts like a big sponge that keeps the water cool and slowly releases it as the season progresses.

“We don’t actually see any more water created. What we see is a change in the timing that it is released,” he wrote.

Through much trial and error, including the disappearance of 13 different beaver he transplanted in Birch Creek, over several years, Wilde said he finally found the right group of hydrologists, biologists, and agency directors to help him create an environment in which the beaver would stay. (He estimates over 100 people have been involved in the entire repopulation process.) 

In 2014, they created 19 mini-dams to encourage the beaver families they imported. He discovered that beaver are highly family-oriented and won’t stay put without their complete family unit,

So Nick and Joe was the one that introduced those beavers and gave him ideas about BDAs to make the water more beaver friendly. And eventually it all paid off.

Last year, beaver were introduced to the area again, and this time, they were still there when Wilde returned last spring to look for them. The creatures had transformed one grassy meadow into a series of terraced dams, with water flowing out each side of them. 

The beaver have built up some of the temporary dams, ignored others, and built their own dams. They are in the process of building a lodge on one of them.

Now, in late October, water is still running in Birch Creek and native cutthroat trout have found their way into the dams. 

Last fall, he and some of the professors from USU held a meeting to let his Birch Creek neighbors know what was going on.

“About 20 people came,” said Lyla Dettmer of the Franklin Soil and Water Conservation office. “

leftAnd Scene! That may be the very best journey of realization I’ve ever read, and I’ve read a few I can tell you. This is a lovely article to tuck away and read again or share with your disbelieving friends.Thanks to the beautiful writing of the editor Necia P. Seamons, it also has the very good sense to end with a paraphrase of a quote we will recognize from our good friend John Muir.

Wilde has learned much in the pursuit of improving the Birch Creek watershed, and his efforts offer much in understanding the impact one person can have, the power of education and the importance of a lifelong pursuit of education, the value of knowledge carried by a community’s older residents, the effectiveness of cooperation, and that all life is connected.

How the west was watered


Our friend Nick Bouwes is in the news again, this time in Scientific American.

CaptureHere’s a nice discussion of his work and findings on ’60 second science’ by Jason G. Goldman. You really should stop what you’re doing and listen because it will make much more sense than anything I’m going to write this morning.

Don’t you love it when people are talking about beavers in Scientific American? Better yet, when SA is talking about a subject YOU ALREADY KNOW about. Yes we are cutting edge here at beaver central, scientific institutions with large budgets and research teams are scrambling to keep up.

It occurs to me that there is a trace of Rick Lanman’s influence evident in this article. His intelligent re-examination of historic writing and lore was fairly unheard of in beaver research before our historic prevalence papers. Now even Bridge Creek is talking about Lewis and Clark as a way to understand what was lost when all the water-savers were killed.

Nice work, Rick!

I’m driving back to Auburn tomorrow to give a presentation to the Fish and Game Commission of Placer. It should be mighty interesting to talk to them about what Martinez did and gained  in contrast their own particularly horrific track record. I’m hoping that they’ll at least start thinking about what else they might be losing by killing 7 times more beavers than any county in the state. Wish me luck.
