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

Tag: Cows and Fish


Some days I just can’t keep up with the hot number of good news stories reported about beavers. I’m already over the moon because Jon picked up the generous puppet donation from Folkmanis yesterday and we received our posters back from the printer. Didn’t this illustration of Alex Riley’s quote, my design and  Coyote Brush Studios‘ beautiful artwork turn out extraordinary?

The plan is to sell these at the festival and by mail, although we haven’t settled on a price yet and technically they’ll be thank you gifts for donations, not sales! They are 18 x 24 and would make a wonderful classroom or visitor’s center poster!

As if that wasn’t exciting enough, this morning there’s a fantastic story out of Alberta about the always inspiring Cows and Fish teaming up with the Miistakis institute to undertake a massive survey an beaver education project, to learn how best approach the landowners.

Is Canada’s national animal a boon or a pest?

Beavers: love them, hate them or ambivalent?

A recently launched survey seeks to learn Alberta landowners’ attitudes about one of Canada’s national symbols. Alberta’s Cows and Fish society has partnered with the Miistakis Institute, a non-profit research group associated with Mount Royal University, on a survey to assess landowners’ knowledge and perception about beavers, their habitat and their management.

There are benefits and drawbacks to having beavers on the property, and survey results will be used to further develop education and outreach on the role of beavers in the ecosystem.

Beavers are a really important keystone species in our ecosystems and they provide some really critical function within our watersheds, and people don’t know a lot of that,”said Miistakis executive director Danah Duke. “We recognize that beavers cause a lot of damage. They take down trees, they flood areas. We recognize that and we recognize that in order for people to be able to coexist with beavers, we need to be able to manage beavers.”

Duke said she suspects many people don’t realize all the benefits beavers provide, such as raising the water table, slowing stream flow, creating habitat for biological diversity and making stopgaps against drought.

“Beaver ponds retain water 50 percent longer than stream sections with no beaver activity, so in times when water is scarce, we find places that have beavers and beaver ponds, water stays on the landscape longer.”

Anyone in Alberta is welcome to take the survey, but the project is aimed at southern Alberta for the moment, said Duke. Organizers are hoping to receive at least 400 responses so that they have statistically significant results.

I am so beyond impressed with the good work Cows and Fish is doing and has been doing since long before Martinez started to play. You can check out the great survey here, I was already their outlier this morning. It’s well done and obviously sneaks in a little education at the same time as it asks questions. Just check out this question which must come as close as a beaver survey can to being a push-poll.

push pollI sure hope during their data analysis they recognize me and wave hello!

A final burst of good news just came from author Ben Goldfarb who is writing the newest book on beavers. He just found out he is the winner of the Aldo Leopold Mi Casita fellowship which means he gets to write his book at Leopold’s home in Taos. It’s a huge honor and beavers and Ben couldn’t deserve it more.

Leopold’s ‘Mi Casita’ residents focus on environment projects

Wolves, beavers and the land ethic are the areas of interest for this year’s participants in the Aldo and Estella Leopold Residency Program, which is now in its fifth year. The residents will spend a month in late summer at the Leopolds’ first home located on U.S. Forest Service land in Tres Piedras.

Ben Goldfarb, a science and environment writer from New Haven, Connecticut, will continue working on a book project about the ecological and hydrological benefits of North American beaver restoration.

In fall 1912, Aldo Leopold, then the newly appointed supervisor of the Carson National Forest, married Estella Luna Otero Bergere, a prominent daughter of Santa Fe. They moved into their new house, called “Mi Casita.”

It was at Mi Casita that Aldo Leopold found his footing as a leader in forestry and conservation. He once described conservation as “the slow and laborious unfolding of a new relationship between people and land.”

The U.S. Forest Service restored the Leopold house in 2007 and has joined with other residency partners to make it available for the Aldo and Estella Leopold Residency Program.

The sponsors of the residency program aimed to promote a transformative “unfolding” by inviting conservation-minded writers, artists, teachers, professionals and practitioners to Mi Casita. Each resident receives a stipend of $500 to help defray travel and living expenses.

Ben says the residence committee was certain Aldo would approve, and we of course agree. He notes that Aldo’s son Luna who wrote so much about fluvial geomorpology never mentioned beavers. But here’s a secret fun fact. Luna was the dissertation chair of Ann Riley who’s recent book on restoring neighborhood streams has a chapter on the Martinez Beavers.

So I think this was all meant to be, don’t you?


Oh those crazy beavers with their penchant for sinkholes and collapsed roads! When are they going to stop harassing us with their rodent ways and let us live peacefully. On ALLIGATOR lake.Capture

Beavers the culprit in 30A road collapse

“We’ve always had problems with beavers where we don’t have a bridge,” said Chance Powell, an engineer for Walton County

One of the great mysteries early Thursday morning was solved after it was determined that beavers were the most likely culprit for the sinkhole that has closed Walton County Road 30A near County Road 283.

Beavers? Beavers!

The Walton County Sheriff’s Office received a call just after 5 a.m. Thursday about a sinkhole on 30A at Alligator Lake.

According to County Commissioner Tony Anderson, who was present as county crews began to fill the extensive hole, a GMC pickup was crossing the section of road when the asphalt began to cave in. The vehicle made it across, but the pickup was damaged and the man driving it was taken to Sacred Heart Hospital on the Emerald Coast with minor injuries, said Walton County Public Works Manager Wilmer Stafford.

“The water that flows under the road became too heavy on one side and caused it to fall in,” said Stafford, who also was at the scene later in the morning.

 The section of CR 30A surrounding the collapse site has been closed until the road can be repaired.

On the surface, the hole appears to be about 4 feet wide and takes up three-quarters of the road in front of Alligator Lake. But officials calculate that crew must deal with a much larger area of damage under the road.

But wait, how do the beavers make the sink hole exactly? Are you saying they tunneled under the asphalt to get away from the alligators, or chew holes in the road with their huge incisors, or that maybe the road was stuffed with willow and they ate it? The article is a little vague on the actual mechanics of destruction.  But I’m sure they’re telling the truth, right? People would never blame a rodent for something just to explain away a problem that their carelessness caused in the first place.

I guess it will stay a mystery, like how beavers live near ALLIGATOR lake in the first place.


 

Come to think of it, maybe they can sign up for the flow device WEBINAR coming soon from our friends at Furbearer Defenders and Cows and Fish. It will be taught by Adrien Nelson and Norine Ambrose and you are ALL invited. It’s a bargain at 5 dollars. Make sure to save your space now.

Learn how to successfully implement flow devices for beaver management in your community with our upcoming webinar, Beaver Flow Devices for Managers.

On April 6, 2017 at 3:30 pm EDT / 1:30 pm MDT / 12:30 pm PDT, Adrian Nelson of The Fur-Bearers, and Norine Ambrose from Cows and Fish will co-host this engaging webinar that will focus on the “whys” and “wheres” of implementing these devices. Managers and supervisors from a range of backgrounds will learn to better understand the applicability of these devices, as well as analyze sites requiring beaver management, and address which type of flow devices are most appropriate. 

Adrian will walk through the different types of devices, and how to make each one successful, as well as various obstacles and needs that may need to be addressed before deployment. The presentation will also touch briefly on ordering and supplies to ensure teams have the right materials for success.

Norine will tell participants of her first-hand experience in learning about and installing these devices in Alberta, and let participants know about the broader beaver collaborative work on education, social science, and management Cows and Fish is involved with the Miistakis Institute, local partners, and support from The Fur-Bearers.

Participants will come away with a better understanding of flow devices, but more importantly why they are useful to successfully co-exist with beavers. A question and answer period will follow.

I actually didn’t know these good folks knew each other, so I might watch just to learn more about their interaction. We will definitely learn things!


MIT continues to make great strides on beaver-inspired wetsuits.

Leave It to Beaver: Why a furry wetsuit could keep you warmer and drier.

Beavers and sea otters lack the thick layer of blubber that insulates walruses and whales. And yet these small, semiaquatic mammals can keep warm and even dry while diving, by trapping warm pockets of air in dense layers of fur.

Inspired by these fuzzy swimmers, MIT engineers have now fabricated fur-like, rubbery pelts and used them to identify a mechanism by which air is trapped between individual hairs when the pelts are plunged into liquid.

The researchers are particularly interested in improving wetsuits for surfing, “where the athlete moves frequently between air and water environments,” says Anette (Peko) Hosoi, a professor of mechanical engineering and associate head of the department at MIT.

Biologists had observed that beavers and other semiaquatic mammals trap, or “entrain,” air in their fur. But, as graduate student Alice Nasto notes, “there was no thorough, mechanical understanding of that process. That’s where we come in.”

The team laid out a plan: fabricate fur-like surfaces of various dimensions, plunge the surfaces into liquid at varying speeds, and use video imaging to measure the air trapped in the fur during each dive.

“We have now quantified the design space and can say, ‘If you have this kind of hair density and length and are diving at these speeds, these designs

will trap air, and these will not,’” Hosoi says.

Ah science! Working so hard to do what nature does without thinking. Not much new in this news, I admit, but I like the graphic. Given the temperature outside yesterday I can understand the need for really efficient entrainment.

I found out this weekend that Lorne Fitch from Cows and Fish is accepting our offer of a transportation scholarship and coming to the State of the beaver conference in February! Whoo hoo! The line up looks really grand with folks from Whales, Scotland AND Germany flying out to present their beaver work, as well as American experts like Suzanne Fouty, Mike Callahan, Damion Ciotti and um, me. I also found out that stalwart beaver champions Sharon and Owen Brown of Beavers: Wetlands and Wildlife will be presenting there. Which is wonderful because I always get a little tired of hearing about ‘beavers as a means to an end’ by Friday! The video below is theirs and narrated by Sharon. You should really think about being there. We’re renting a house so we’d invite you for dinner and everything.

I’m not sure what to think about the Whit Gibbons learning curve. He wrote back that he’d look at the website and I sent him all sorts of educational links. His column is obviously syndicated and has appeared in a few other papers. But today’s appearance bears this headline:

Beavers Make Great Neighbors

Same exact column, but this one is printed in New York.  Authors don’t usually pick the headline. So who knows what the explanation is?
