Wow! Wisconsin just got a whole lot smarter about beavers. Bob Boucher’s study is making a major spash and I couldn’t be happier.

New Study Finds Beavers Could Be Key To Preventing Flooding On The Milwaukee River

Now, there are calls for beavers to return — not for their fur — but for the potential impact they could have on flood mitigation in the Milwaukee River watershed. A recent collaborative study between the Milwaukee Metropolitan Sewerage District, Milwaukee Riverkeeper and UW-Milwaukee analyzed the prospect of increased beavers on the watershed.

GO LISTEN to the whole glorious thing, and remember that Wisconsin is usually soooo stupid about beavers they blow up dams to help fish AND think there are more beavers now than there used to be. Fantastic work Bob. Beaver hats off to you!

Here’s  what I spent entirely too much time on yesterday. They lyrics just fit wayyy too well, It can’t be a coincidence. From “defending a COLONY” to ending with RISE UP.  I know I’m very weird but if you listen to the sounds track and read my lyrics you’ll see they mostly scan. Beavers need  their time on stage.

Beaverton

You might remember that on valentine’s day I did a talk with Bob Boucher for the Oakmont Symposium in Sonoma. He was very excited that the final draft of this academic paper had just been released and talked about the difference this could mean to Milwaukee. Fittingly this research was paid for by a grant from the local water agency. Which is the kind of thing that makes sense but rarely happens.

UWM researchers find that beavers could be a remedy for downstream floods

A new study by two UWM researchers shows that restoration of an animal that Wisconsin was known for 300 years ago – beavers – could be a part of the solution.

Enough of the dam-building animals living in the right spots along creeks and streams can alleviate flooding in some of Milwaukee County’s worst-struck areas, according to research by Qian Liao, an associate professor of civil engineering, and Changshan Wu, a professor of geography.

When beavers build homes, called lodges, in wetland habitats, they also construct dams to create a pond so that they can enter the lodge from under water. A significant amount of water backs up as the pond forms, and that hinders fast-moving water, which has a cumulative effect downstream.

Whoohoo! Everything about the opening is perfect, except for that line about Wisconsin knowing beavers for 3oo years. Hmm I’m thinking they’ve been around a bit longer than that. Maybe you want to check in with the Oneida or the Chippewa about that? They might have other opinions.

Bob Boucher, founder of the environmental advocacy organization Milwaukee Riverkeeper, proposed the study to officials at the Milwaukee Metropolitan Sewerage District, which funded the research.

“If there are hundreds of beaver dams distributed across the entire watershed, you have many locations where you can reduce the water flow,” Liao said. “And not just the volume, but also the timing, so that the combined delay at each dam has a significant impact on the downstream peak flow.”

Collecting data with their cellphones, Boucher, Holloway and students Max Rock and Madeline Flanner spent much of 2020 visiting 163 locations on the GIS maps. They made observations either by canoe or by hiking into areas at bridge road crossings to evaluate whether locations had ample food sources and the kinds of trees the animals use for building.

A cellphone app that Rock developed helped the team rank the locations by quality, based on all the data. What they found was enough habitat to support around 4,500 beavers – or about one family for each 100 acres of wetlands

That’s right. Bob is so skilled at maneuvering these things he got Milwakee sewage to pay for it and a student to develop a cell phone app that could study it.

Liao fed the model different scenarios of beaver dam activity at 52 locations that would provide the highest potential to reduce downstream flooding, while also having ideal conditions for beaver. According to the model, dams would reduce the peak flow by between 14% to 48%, depending on the details of the storm, but also on the dam location.

“For example, if the storm was relatively uniform across the entire watershed, then you would have the highest reduction of water flow,” he said. “But if the storm dropped most of its rain on southern areas of the river watershed, then dams located upstream where there’s less rain will have a diminished effect.”

How awesome is this research? Beaver dams can make a huge difference. But we need MORE OF THEM. That’s what I take away from this article.

“There have been other studies that showed the effect on flooding of introducing beaver dams, but those studies only measured the effect a few miles downstream,” Liao said. “What we did is a little different. We looked at it on the watershed scale.”


Yesterday I did a practice run through of my Oakmont Symposium presentation Sunday. I learned that the organizers Gabriel Campbell and Judie Coleman are both powerhouses and Bob Boucher’s talk about flooding in Milwaukee is going to knock your socks off. I had to laugh initially when I saw that the website had accidentally shortened the title of the talk to “Spend valentine’s day with the conservationists who mate”. HAHA. As in we are the only ones who get to, Other conservationists can only dream about mating. Smile.  I was also encouraged to share the link to the talk with friends and family so consider yourselves all invited. Click on the image to go to the talk at 10:30 Valentine’s morning. And if you’re busy sipping champagne and oysters with your beloved that morning I’m told that it will be recorded and made available for viewing later.

This morning we get treated to an excellent letter from Renee Espenel  from Portland. It is lovingly tited

Letter: Beavers are essential

I am writing today to thank state Rep. Pam Marsh and Rep. Rob Nosse, and state Sen. Chris Gorsek, for representing the Beaver State and sponsoring House Bill 2844, which would remove the predatory animal designation from beavers in Oregon.

HB 2844 would allow ODFW to issue permits, regulate management and give the state an opportunity to collect valuable data on beaver populations and their impact on a healthy environment and ecosystem.

Beavers are essential in creating wetlands and habitat for salmon, and we are just now realizing their potential effect in improving fire resiliency, capturing carbon and improving the quality of our drinking water.

Can I get an Amen? Well said Renee! We are happy that lots of Oregonians are noticing that beavers matter to more than trapping interests.

Changing how we manage this species, would benefit Oregonians and ensure a sustainable and healthy ecosystem for generations to come. Please reach out to your legislatures and ask that they support HB 2844.

Just remember. We’re not Gods. We don’t need to change everyone’s mind. Just the minds of the people that drink water and don’t want their homes to burn,

That should do it.


It’s time to start thinking of the next hurdle. And start getting my video together for the upcoming Valentine’s presentation at Oakmont Syposiumwith Bob Boucher. I am happy about the timing because it’s a great opportunity to plug the Summit which is coming soon thereafter, In the meantime he sent me some awesome photos for the website that I thought you’d want to peruse.

Beavers:  Conservationists Who Mate for Life

Happy Valentine’s Day!  And the perfect animals to celebrate are beavers.  Why?  They mate happily for life.  And not only is that kind of cool, but they are also a “keystone” animal.  When these resilient critters aren’t around, the ecology doesn’t work right; when they are around, life thrives. Beavers are unsung heroes that shaped our country in more ways than one.  Bob Boucher and Heidi Perryman, an “accidental beaver advocate” and will charm us with their fascination for these amazing animals.

 

You can tell already the talk is going to be pretty dam fantastic.


The horrible glass fire is threatening our friends at Safari West AGAIN, so if you have any leftover space in your thoughts and prayers please after praying for our constitution. our supreme court and asking to spare members of your family from Covid, please send some metta and loving kindness their way. Fire is very much on our minds in California. Like mercy it droppeth as the gentle rains from heaven. Ash is covering our decks and our gardens and the smell of smoke woke me up.

I’m so glad Rick Lanman updated his wikipedia page.

Beaver ponds as wildlife refugia and firebreaks in wildfires

Beaver and their associated ponds and wetlands may be overlooked as effective wildfire-fighting tools.[145] Eric Collier’s 1959 book, Three Against the Wilderness, provides an early description of a string of beaver ponds serving as a firebreak, saving the home of his pioneer family from a wildfire in interior British Columbia.[146] Reduction of fuel loads by beaver removal of riparian trees, increased moisture content in riparian vegetation by beaver-raised water tables, and water held in beaver ponds all act as barriers to wildfires. In a study of vegetation after five large wildfires in the western United States, riparian corridors within 100 meters of beaver ponds were buffered from wildfires when compared to similar riparian corridors without beaver dams. [147] Professor Joe Wheaton of Utah State University studied the barren landscape left one month after the Sharps Fire burned 65,000 acres (260 km2) in Idaho’s Blaine County in 2018. He found a lone surviving green ribbon of riparian vegetation along Baugh Creek,[148] (see image) illustrating how a string of beaver ponds resists wildfires, creating an “emerald refuge” for wildlife.[145] Lastly, two studies of the Methow River watershed, after the 2014 Carlton Complex Fire burned 256,000 acres (1,040 km2) in north central Washington State, have shown that beaver dams reduced the negative impacts of wildfire on sediment runoff, reduced post-wildfire sediment and nutrient loads, and preserved both plant and macroinvertebrate communities.[149][150]

In addition to citing Emily and Alexis fantastic paper he also came across an outstanding thesis by Edin Stewart entitled: Beavers Buffering Blazes: The Potential Role of Castor canadensis in Mitigating Wildfire Impacts on Stream Ecosystems. I will add the whole paper to our library but suffice it to say it concludes whoppingly with the following sentence: “our study provides support for the hypothesis that beaver dams reduce the negative impacts of wildfire on stream habitats and communities.”

Yup.

Speaking of fire, one of the evacuations I heard on the news yesterday was the Oakmont region of Sonoma. This has been on my mind lately because of the famed Oakmont Symposium which is a dynamic and coveted  and widely attended lecture series. I think we met a fellow from the group years ago at the dam watching beavers in Martinez.

Well, recently one of their influencers was vacationing out of state and wound up running into Bob Boucher of beaver fame in Wisconsin and they concocted the idea of a beaver talk for Valentine’s day. Zoom friendly, of course. Thinking it would be excellent to add a California beaver voice Bob asked me to ‘co-present’ with him. And the host recently asked for a thread that would tie it all to theme of the day.

So I spent yesterday working on this. Fire notwithstanding, I assume this will happen?

Some say the world will end in fire,
Some say in ice.
From what I’ve tasted of desire
I hold with those who favor fire.
But if it had to perish twice,
I think I know enough of hate
To say that for destruction ice
Is also great
And would suffice.
