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

Tag: Jeff Baldwin


If you’re lucky in this world people report on your scholarly achievement when it’s newly published. People like shiny new things. You can show the article to your mom or dad and they will feel as if their college dollars were well spent. It helps you get hired so you can support your own research next time. That’s what happens if you’re LUCKY.

You would be crazy to expect them to be talking about this research 5 years later. Even 2 years later is pretty unlikely. But not if you’re Jeff Baldwin.

Beaver Politics in Oregon

A North American Beaver – Castor Canadensis – sitting in the grass grooming itself. Along the shore of a wetland pond. Near Portland in Western Oregon.

With climate change transforming the American West, an industrious mammal could help mitigate some of the worst of the coming drought and flooding crises. The West is getting drier in the dry season and more prone to flooding in the wet season. Beavers could well be a relatively low-cost part of resiliency efforts. As natural ecosystem engineers, these largest-of-North-America’s rodents “increase water storage in ponds and surrounding floodplains, thus slowing winter flows, increasing riparian and meadow water availability, and extending stream flow up to six weeks into dry summer seasons.”

But in Oregon, the Beaver State, beaver politics, for want of a better term, make reintroduction problematic. Scholar Jeff Baldwin details the institutional obstacles to the use beaver in mitigation initiatives. Public policy is mostly controlled by those opposed to the animals. Across seventy-five percent of the state, a predator designation means they “may be killed without record or regulation.” The same statute also guarantees that no information is collected about these killings. Evidence of beaver extirpation is therefore anecdotal and “dismissed as such.”

For more than a century, “state and federal governments have vacillated between promoting and killing beaver.” For instance, Oregon banned trapping in 1899; rescinded the ban in 1918; re-instituted the ban in 1932; then allowed trapping on agricultural land in 1951. There aren’t very many licensed trappers today, but they have a strong lobby. And with the predator listing, you don’t need even a license to kill them in plenty of places.

Well that is crazy I agree. But to be honest things are no crazier in Oregon than they are in California. Probably a little LESS crazy to be honest. We are all suffering from no water or too much water and we’re both highly flammable. We both should be standing in line waiting for our turn to have beavers on our land.

But of course we’re not.

Meanwhile, reintroduction efforts, in cooperation with landowners, in the 1940s successfully boosted beaver populations, a history forgotten by the Oregon Department of Fish and Wildlife professionals Baldwin interviewed.

Before all this, beaver populations across North America were attacked with gusto to feed a European market that had already trapped out Europe’s indigenous beaver species. Estimates of the pre-colonization population of beavers in North America run from sixty to three-hundred million. Today, the population is estimated at three to six million, mostly in Canada and Alaska.

Journals of explorers and trappers testify to Western landscapes built in part by beavers. Writes Baldwin, “Now-channelized and arid valley floors across the American West were once difficult to traverse due to multiple channels and broad riparian flood plains covered by dense vegetation.” Could such landscapes, created and maintained by beavers, be brought back?

Gee I don’t know. Something seems to be standing in our way. Something pesky and wide spread. What could it be? I can’t quite put my finger on it.

Examining “the culture of land and wildlife management professionals and policy makers,” Baldwin conducted forty key informant interviews and did a “critical review of literature published by state wildlife management and climate change institutions.”

He found five institutional obstacles to beaver recolonization and/or reintroduction. Two were legislative. Beavers are listed as predators—pests of agriculture crops and products—so they can be killed with impunity. And climate change policy recommendations have to be “politically neutral,” meaning they are essentially impossible to enact, as neither beaver nor climate change is considered apolitical by many of the involved bureaus and land managers.

The three other obstacles were “positions shared by many wildlife management specialists.” These were: there are enough beavers already; licensed trapping doesn’t affect population; and reintroductions are ineffective. Baldwin’s research undermines all three of these assertions.

Alright JEFF! Tell us why!

In fact, “the benefits of beaver recolonization,” are well-established and well-documented, but Oregon’s political process stymies action. Between 2008 and 2017, nine state agencies and working groups released thirteen reports addressing climate change and wildlife and land adaptation. Baldwin notes that none of these mentioned beavers. To avoid controversy and legislative veto, the reports “generally avoid calls to make any material changes.” [Baldwin’s italics]

In Oregon, the Department of Agriculture “also represents the timber industry,” and since beaver reintroductions can lead to “road failure,” the powerful industry demands the right to control beavers on their land.

Politics and attitudes don’t change as fast as the climate. The fate of the giant Castoroides beavers, as large as bears, may be a teachable moment here: climate change did them in.

Baldwin concludes that de-listing of beavers as predators would be a key step to re-beavering the Beaver State. Meanwhile, Oregon’s indigenous tribes are already paving the way with beaver reintroductions of their own

Well they say all politics is local. I would say that “All politics is beavers”. Beaver is the ultimate NIMBY. Try living with a beaver dam in your city for a decade and you’ll know what I’m talking about.

The article ends with a nice reference to Jeff’s paper and a link so readers can see for themselves. Remember that Jeff is at Sonoma state now and was the one responsible for getting the beaver  summit to be hosted there. He was thrilled when I sent him this news article. You can see why.

Maybe if we drown the west in good news about beavers SOMEONE will finally start paying attention.

 


My my my. I thought when the fire story broke in National Geographic that was a good day for beavers. I thought when the Washington Post praised Ben Goldfarb’s book that was a good day for beavers. I thought that when the beaver festival got praised in the congressional that was a good day.

But this? This is a superCalibeaverfragileecosystemsave the planet kind of day.

First the staggering news. Guess what IS going to happen because I just found out Sonoma State is going to be the host. Apparently the answer to the question is California ready for its own beaver summit is YES because Professor Jeff Baldwin took the idea to his friends at Sonoma State and as of yesterday at 3:30 in the afternoon  a beaver summit was officially approved!

The first planning meeting is scheduled for a couple weeks and more details will soon be forthcoming like when and who and where to register. At the moment I’m surrying around with a clipboard like a stage manager saying we need a logo, a website, a short film maybe to announce it, and everyone’s feet marching in the same direction for about a day. Is that so much to ask?

It’s a long way from happening, but it’s a lot closer to actually happening than it was when it was just a crazy idea in my head so HURRAY! Bring on the Cal-beaver Summit!

In an unrelated by very appropriate burst of good news the beavers without borders film is being released this weekend and you can sign up to see it for free!

Beaver Trust launches film to promote beavers as friend not foe

Beavers can play an important role in flood prevention and as such deserve our support and care, says the Beaver Trust, which is launching a short documentary film to enlighten us as to their many skills

Beavers Without Borders explores the benefits and challenges of reintroducing beavers to our landscapes. ‘It’s a critical time for beavers, with the UK Government deciding on their future in England, and calls for the Scottish Government to allow their relocation in Scotland. We hope our film evokes the buzz of life in beaver wetlands, inspires people to welcome beavers back, and helps nurture a reconnection between people and the rest of nature,’ says trust chief executive James Wallace.

A free live YouTube premiere of the film takes place on  Sunday from 7pm-8pm. To register  visit https://bit.ly/366N2Zg.

That’s 11 to 12 my time so completely watchable if you want to register. I don’t know  tight space will be and whether there’s room for many Americans to hop aboard, but they let me in an now it’s they win an entry on this tiny website.

Just remember how good the trailer was. Bring your own popcorn and handkerchies just in case.

Critter Number 5 — The Beaver

Shall the year of the buck-toothed beaver be upon us soon?

Beavers in this country happen to have their own fan club. I’ve heard from a few of its members this past week after my story about beavers was posted online.

“We were so happy to see it here in Martinez, CA,” Heidi Perryman, president and founder of an organization called Worth a Dam, wrote in an email. In her town, “we worked to coexist with beavers nearly 10 years ago by installing a flow device to control flooding. Now because of our safe, beaver-tended wetlands we regularly see otter, steelhead, wood duck and mink in our urban stream! And celebrate every year with an annual beaver festival.”

That’s right, folks, an annual beaver festival.

What’s unusual about that I ask? It’s always weird to discover my own words on someone else’s web page, but I’m really happy I wrote Whitney after her Urban beaver article last week. She wrote back that she had come across information from our website but felt it was too far away to be relevant to her article.

I guess we just got relevant.

Perhaps we are entering into a new age, the age of the interminable beaver. These buck-toothed, fluffy (when dry), flat-tailed tumblers of trees and engineers of our ecosystems are beginning to get a little more recognition rather than sheer derision in neighborhoods where they were once considered a nuisance.

When I told our editor Karl Blankenship that I wanted to write this story about beavers — spurred by a study out of the Northeast that looked at the nitrogen removal attributes of their dams — he sent me a trove of notes he’d collected about the critters. We’ve been watching beavers for a while, waiting for the pendulum to swing back in their favor, I suppose. Other comments on the story indicate the Year of Beaver might not be far away for our Bay area as well:

“Let’s hear a cheer for the eager beavers and clean water!” writes one commenter.

I like everything about this, but I disagree with Whitney and Karl in one respect. We can’t wait for the pendulum to “swing back”.We have to push it there.

Here’s just on reason why:

Capture

Climate models forecast significant changes in California’s temperature and precipitation patterns. Those changes are likely to affect fluvial and riparian habitat. Across the American West several researchers and civil society groups promote increased beaver (Castor canadensis) presence as a means to moderate such changes. Where beaver dams are persistent, they may sequester sediment and create wet meadows that can moderate floods, augment early summer baseflows, sequester carbon in soils and standing biomass, decrease ecological problems posed by earlier spring stream recession, and potentially help cool early summer and post-wildfire stream temperatures.

Go read the entire article here. Like any good researcher he spends a long time explaining why its true, then says it might not be true in other areas and more research is still needed. He also ends with the gloomy paragraph that beaver damage to infrastructure might be too expensive for most areas to manage. Hrmph. But I like any article that clutters the journal of fish and wildlife with more beavers, and Jeff’s a good beaver friend. So maybe they made him add that last paragraph.


Finally, a lovely 5 minutes from our friend Peter Smith of the Wildwood Trust.

 


Another fourth of July safely passed. We stayed on sight until 9 and the beavers and kits wisely stayed upstream. Except for Junior who went down to the dam when everyone was on the bridge and demonstrated damming behavior. There must have been 100 separate photos taken of him as people stopped to watch on the way to the fireworks.  We made sure there were signs for the festival which people remarked on and stopped to look at too. The best thing heard were several comments of “Where else can you see beavers on the way to fireworks?”

No where, I think.

Lots of odds and ends to talk about to day, as my in box has been accumulating. Let’s start with the annoying and work up to the inspirational, okay? The first was reported this weekend in the Sacramento Bee. Remind me never to hire a lawyer or doctor that had such a hard time remembering things in school that he used lies like THIS!

Their video study guides aim to keep it sketchy

MurderFinal

CaptureTwo video series, dubbed SketchyMedical and SketchyLaw, offer short, animated videos that illustrate biological or legal terms and concepts, using wordplay and nonliteral interpretations of the terms to help students better remember.

 The 11-video SketchyLaw series on criminal law features animated sketches of beavers chewing on bark to represent the various legal scenarios in felony murder; “BARRK” is the acronym commonly used by law students to remember the five felonies that can lead to a murder charge if someone dies in the process. As the animation progresses, Mueller narrates off-camera to explain the terms.

Beaver in trees so you can remember to watch out for murder charges? Call me a cynic. But I think in this world there are two types of brains. Let’s call them “Bowls” and “Colanders “. And if information is draining out of your head as fast as you put it in, you might be great at making spaghetti, but even if tree-climbing rodents can get you out of law school you won’t remember what your clients tell you anyway! Or what color tie the judge hates, or the best way to start oral argument with a mostly female jury. You get the idea. Law and Med school (and graduate school for that matter) are practice arenas. You have to make it there before you hit the big leagues.

_____________________________________________________

Speaking of the big leagues, there’s a new kid on the beaver management block worth talking about. Jakob Shockey attended the State of the Beaver Conference this year, met with Mike Callahan and others, and decided the watershed group he worked with needed a beaver expert. Folks helped raised funds to send him off to Massachusetts to train with Mike which I wrote about here. Now he’s opened his own shop with website here.

Capture Flow Devices

Flow devices can be used in a variety of situations to keep a beaver pond at a certain water level, or to protect a culvert or spillway from damming activity.

These designs essentially trick beaver into believing that their dam is holding water while sneaking it out, either through a caged drainage pipe (pictured) sunk into the middle of the pond or a trapezoidal protective fence.

 Over time, these solutions are far more cost-effective than lethal management of problem beaver, while also retaining the ecosystem services of beaver on the landscape.

 Contact us for more information on a potential solution to your beaver issues.

Welcome to the beaver ‘hood Jakob! It’s wonderful to have another expert on the west coast. We’ll be sure to send lots of folks your way. I already added a link to our blogroll, but let Worth A Dam know if we can help get the word out or maybe with a beaver photo for your cover page. We are happy to assist friends!

_____________________________________________________________

Finally, I received this great paper from beaver friend close to home Jeff Baldwin at Sonoma State. In it he writes deftly about his idea of the way beavers shaped the country. It is a fairly intellectual paper, but you will be smarter at the end of it than you were at the beginning. Jeff already proved himself the intellectual heavy weight of the beaver crowd at the conference, where he thoroughly impressed everyone with his careful capacity to scour the literature and report unpopular truths even to a roomful of acolytes. He’s a brave man, and a very, very smart one.

Beaver as Historical Actors: In Theory and Practice

We now know that beaver dams change landscapes and hydrologies in important ways. Like the milldams on the Appalachian Piedmont they trap sediment. In north central Oregon, Pollack et al. found that in their first year beaver dams trapped enough sediment to raise the stream bed an average of 0.47 meters. Though stream bed aggradation slowed to about 0.075 meters (about 3 inches) in the sixth study year, the area of aggradation broadened significantly as sediment was increasingly deposited across the entire riparian area. Typically, given enough time beaver ponds fill in and become swales and then wet meadows.[4]

 Beaver dams essentially spread hydrologic flows across the entire flood plain. The surface of beaver ponds are typically at or near bank-full, meaning that a small increase in flow quickly expands the pond to cover its flood plain. Thus, high stream flows spread nutrients to riparian communities rather than washing them downstream where they have caused hyper-eutrophication and accompanying dead zones. Unlike incised streams whose surface is far below the flood plain and so drain water from the ground below flood plains, beaver ponds charge those soils and aquifers with water. Westbrook et al. explain that typically about one half of the water that flows through a dam-pool system travels through the soil. There it maintains moisture in wide riparian zones long in to dry periods. Typically water re-enters the stream at the temperature of the soil, a cool 54° F (12° C), conditions preferred by many fish species valued by Americans.[5]

Finally, when beaver are present, streams tend to have multiple shallow and shifting channels. For low gradient streams, ‘the model’ that conservationists have been working so hard to emulate bears little resemblance to an ‘un-disturbed stream.’ While one may be impressed with the extent of milldams in Appalachia, that anthropogenic environmental dialectic pales when compared to what beaver did, and still could do, to North American waterscapes. Yet very few historians, environmental historians, or environmental geographers take beaver, and other non-human beings to be historic actors, in and of themselves.

While beaver dams could help mitigate the effects of climate change, they could also help moderate the process. Because ponds are nutrient rich they become eutrophic, and as biota dies and decays anaerobically the ponds and meadows trap the carbon embodied therein. Similarly, the wetland soils around beaver ponds also work to sequester carbon. On a landscape scale, beaver ponds both moderate atmospheric carbon loading, and at local and watershed scales they mitigate increased seasonality. These biospheric relationships would, if allowed, respond in significant, novel, and historical ways to anthropogenic changes to Earth’s atmosphere and climate.[39]

Without the ecology background to inform my reading, I found this paper a little smarter than my brain could process. But I am happy to share it with s better minds than my own. On the most basic level, I am certain that Jeff is right and beavers function as actors on the human landscape and story. I am confident that if we read a little more of Dr. Baldwin we’ll be better equipped for these understandings. Thanks Jeff for your hard work!


Cheryl and Lory were down on kitwatch last night and met Moses Silva who proudly displayed footage of Mom beaver with her new kit from 3:00 am that morning. He had been out at 1:00 all week and seen nothing so decided to stay all night!  He was happy to share the news, but apparently not the footage. We’ll get the little tyke (and his brother or sisters?) soon. In the meantime, congratulations Martinez, it’s a beaver!

storkbeaverAs if that wasn’t good enough news, an amazing workshop will be making its way down the Pacific Coast with the help of NOAA, USFW and PSU.

Using Beaver to Restore Streams — the state of the art and science

1-day workshops for practitioners, landowners, land managers and regulators

Nov. 20, 2014 – Juneau, AK

Jan. 14, 2015 – Seattle, WA

Jan 21 &22, 2015 – Portland, OR

Feb. 12, 2015 – Weed, CA

To Register go here.

Course Fee: $50

Presenters:

Michael M. Pollock, Ph.D.  Chris E. Jordan, Ph.D.  Janine Castro, Ph.D. 
Gregory Lewallen Ecosystems Analyst Mathematical Ecologist Fluvial Geomorphologist Graduate Student
NOAA Fisheries NOAA Fisheries US Fish & Wildlife Service Portland State University
NWF Science Center NWF Science Center & NOAA Fisheries

These workshops will be offered for a nominal fee through a partnership with US Fish and Wildlife Service, NOAA Fisheries, and Portland State University, Environmental Professional Program.

Using beaver to restore streams is rapidly gaining acceptance as a cost-effective technique to improve aquatic habitat, especially for salmonids. Regulatory and institutional obstacles are being reduced or removed as scientific advances continue to demonstrate that beaver can restore stream habitat far more effectively, and at a much lower cost, than many traditional stream restoration approaches.

Join us for an intensive 1-day workshop symposium for the beta release of a state-of-the-science manual regarding the use of beaver to restore streams. Workshops will be interactive with the audience as we walk through the manual and describe its use to facilitate the restoration of streams. We will provide assessment tools for determining how, where, and when to use beaver in stream restoration. Also included will be a discussion of the regulatory process and how to maximize the probability of successfully obtaining permits.

As a leader in aquatic habitat restoration, your feedback on this document is very important to us and necessary to create an effective tool for restoration using beaver. We encourage you and your colleagues to attend a workshop and to spread the word. Please let us know if you would like to join us and/or if you know of particular groups who may want to attend by responding to this announcement, so that we may adjust the number of workshops as necessary.

Thank you and we look forward to hearing back from you.

Michael Pollock contacted me a few weeks ago about how to get the word out. (he actually introduced me to Mary Ann as a kind of  ‘beaver Maven‘ which ignorance forced me to go look up! After the initial glow wore off, I and lots of others implored for a Northern California appearance.

Yesterday Mary Ann wrote me that they are looking at just such a venue. Did I have any suggestions about a meeting place that could accommodate up to 50 attendees? I introduced her to Jeff Baldwin at Sonoma State who is very interested in the idea. And also suggested to the head of SRF that it might be worth combining it with the salmonid conference in Santa Rosa next year. Dana Stolzman wrote back  very interested in the idea and I think everyone’s talking, which means if we just sit tight the conference may come to US!

(Maven!)

Meanwhile I’ve been working hard to get the word out about the festival. Hopefully we’ll have an fullhouse in the park that day, and a full cast of new beaver kit characters to feature! Stay tuned.
