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

Category: Who’s saving beavers now?


Poachers!

Beaver website poachers! They’re all around us. Hardly a day goes by that I don’t see some item from this website used without permission OR get some more slightly more responsible human asking me to use an image. A photograph. A poster. Our entire library. It’s all for the good of the beavers, and you want to help beavers right?

Two weeks ago I was approached by the Beaver Trust in England asking about our beaver as ecosystem poster. They wanted to set up a zoom chat to ask me about out work and its origins. Silly me, I thought they wanted to know about our community efforts. But they really only wanted the poster. It was such a smart design. Could they use it? Could their artists recreate the shape and animals for their country? Would they need to pay me royalties?

hahaha.

Just take it I said not entirely unresentfully. I’ll be happy to see it drawn with British wildlife. And this morning Mike Callahan wrote that they are trying to make the “Beaver Institute Website the premiere online library in the world” so can they please have ours? Oh sure, Take what you like I said feeling like a food bank on Christmas eve. Why should I horde beaver information anyway? We all want it shared freely with everyone. Share share, That’s fair, right?

And the thing that bugs me most is that both those names, the beaver  trust and the beaver institute have bigger profiles and more respect that this rinky little operation will ever get, It’s like robbing the local pastor to pay the Vatican. But go ahead. I’m sure I’ll one day be lost in the annals of beaver history but I will have contributed. It says so right in Ben Goldfarb’s book.

And that’s something.

Meanwhile there’s good news from Carolina so I should stop complaining.

Living with Beavers

Beavers build dams to raise the water level until deep enough for swimming. They build lodges out of sticks and mud for their homes, unless they are residing in deep rivers or lakes where they dig and live in burrows in a high bank with an underwater exit for safe getaways.

“Beavers are truly nature’s engineers and, like people, will manipulate their habitat according to their needs.”

“Beavers are truly nature’s engineers and, like people, will manipulate their habitat according to their needs,” says Colleen Olfenbuttel, state black bear and furbearer biologist with the NC Wildlife Resources Commission. “The habitats they create can be both beneficial and cause conflicts.”

Beaver dams can produce flooding in unwanted places and result in millions of dollars in property and agricultural damage in North Carolina without management, Colleen explains. But their ponds can be an asset for both people and wildlife. They create new habitat for many other species, and the flooding creates wetlands and can recharge groundwater. The pond becomes home to fish, waterfowl, raptors, reptiles, mammals, native plants, and insects. The wetlands created by beavers help clean the water of sediments and control erosion. People can find abundant recreational opportunities around beaver ponds, such as hunting, canoeing and fishing.

Gosh, Well WE know its true obviously. But I didn’t know NC Wildlife Resource Commission knew it was true. That’s nice to hear from your side of the country. Tell me more.

Ask folks who have had beavers for neighbors, and you’ll get mixed reactions. Some enjoy watching them and appreciate the ecosystems created by their dams and ponds.

“We have a little off-channel pond someone built on our property before we bought it. Their little dam made the pond a bit deeper, and it was fun watching them,” says Kim Beall of Franklin County, who enjoyed watching her beaver neighbors.

John Hilpert, also in Franklin County, says beavers built several dams across Tooles Creek at one point. “If quiet, we’d enjoy watching them play. So, they cut some minor trees like sweet gum — the increase in wildlife and flood control was an excellent tradeoff.”

Others, however, are not so happy with their beaver neighbors. The Foushees in Person County had their beavers removed by licensed trappers because of the flooding they caused. Judy Spruill of Washington County also had a colony of beavers removed from her farm because of flooding.

Well sure, You can tell how good people are at solving problems by how they get on with beavers. If they’re thick and slow like a bag of hammers everything looks like a nail. And the beavers will be killed right away. If they are resilient, resourceful and creative like Martinez however, something else happens entirely.

The second solution is learning to live with beavers and taking advantage of the benefits of a beaver-created wetland or pond. The NC Wildlife Resources Commission has a number of science-based options for resolving beaver damage while still maintaining beavers on your property. Some options include fencing off the area with trees you want preserved or putting wire mesh around individual trees — though not too tightly, or the beaver can still chew on the bark. Control flooding with water level control devices, typically made from drainage pipes. Designs for these water control devices can be found on the NC Wildlife website.

“Thankfully, we can have the benefits of beavers on the landscape, while also having methods to resolve conflicts when they occur,” Colleen says, “which is a good balance for North Carolina.”

Ahh we have the solutions alright, Just not enough people who would rather solve a problem than kill it.


Variety is the spice of life,

I mean when you review beaver news every day you hear the same thing over and over. Residents saying “Don’t kill the beavers because they save water” or “save fish” or “save wildlife”. But you don’t hear this very often.

“We are worried about the abundance of wildflowers and pollinators we had in the area”

Tiny will work with residents on better ‘beaver-friendly’ solutions

Leave it to beaver to create a link between the township and residents of a neighbourhood.

The connection is between residents of Wymbolwood Beach and municipal staff that removed a beaver dam in the area of Skylark Road and Tiny Beaches Road South.

Tiny resident Julia Aronov took up the matter with council at a November meeting. Staff brought back an answer at a January meeting, after putting together the pieces of the puzzle.

“The Township of Tiny is an environmentally focused municipality,” said Tim Leitch, director public works and interim chief administrative officer. “Unfortunately, we do have areas in the municipality that have beaver activity. It is part of our environment and we definitely do not want to do anything to disturb that.”

However, he said, there are some confined areas within the township’s drainage network that experience accumulation of debris due to beaver activity.

‘Tiny’ is in fact a regular sized town in Ontario near Toronto. It’s about 2500 miles from our friends at Fur-bearers but they apparently have gotten the memo anyway. Just listen to this.

“We want them to involve us in this,” she said. “We had so many people saying they could help build a pond leveller.”

According to Nature Conservancy Canada, “pond levellers are glorified pipes that extend through a beaver dam and prevent upstream flooding. Setting the pipe at the desired water level allows any excess water to flow through the pipe to the downstream side of the dam. This allows the beavers to remain in their dam, while alleviating upstream flooding nuisances.”

Aside from this, when Aronov had approached council last year, she had included myriad documents to the effect in her presentation. 

“I’d like to see if the township is willing to try a more friendly method,” she said.

Hmm I’m not sure I’d call them “gloried pipe”. But okay. They know what they are and they’re willing to help install one. What does the city say about that?

“The research we’ve done…the devices still require maintenance and a lot of them just make it easier for us to take away the sticks from in front of the culvert than inside the culvert, he said. “One commitment that I did make was that where we see a situation where we’re able to anticipate problems occurring, we will reach out for different approaches and hopefully be able to develop some plans to minimize any impact on the beaver activity.

Boy that was some research. You must have done hours and hours of research to come up with that bit of gossip. I can just imagine city staff now, sitting bleary eyed in front of a stack of books at county library in the wee hours trying to keep awake by drinking iced coffee and charcoal biscuits.

Or hey, maybe when he says “research” he means “Bob’s brother in law in YK told him that those things never work!”

The idea isn’t that the build outside the culvert. The idea is that they don’t build at all. Here watch this helpful video and get your grandaughter to slap you several times.

Maybe leave the research to the librarians next time? And you can get back to filling potholes.

“The Township of Tiny is an environmentally focused municipality,” said Tim Leitch, director public works and interim chief administrative officer. “Unfortunately, we do have areas in the municipality that have beaver activity. It is part of our environment and we definitely do not want to do anything to disturb that.”

However, he said, there are some confined areas within the township’s drainage network that experience accumulation of debris due to beaver activity.

“With this blockage,” added Leitch, “damage can occur to the infrastructure, private and public property, within hours. It’s our responsibility to ensure these blockages are removed.”

I’m sure if everyone your team works very very hard they can make Tiny advances in how beavers are managed.


ASWM is the association for State Wetlands Managers. It’s a national non-profit group that webinars and certifications  for river stewards across the country. They are a remarkable resource that is mostly free to access. And they just posted the four webinars about beavers and wetlands from 2020. Of course every one starts with OUR PHOTO because we are the beavers for the ages.

2020 Beavers and Wetland Restoration Webinars

The Association of State Wetland Managers (ASWM) and the Bureau of Land Management (BLM) have collaborated to develop a series of webinars introducing the topic of restoration of aquatic ecosystems through the reintroduction of beavers, the use of beaver dam analogues (BDAs) or restoration designed to attract beavers to an area to contribute to changing hydrology and restoring ecosystem services. This webinar series has been planned by a national workgroup of beaver restoration experts and webinars are presented by expert practitioners, managers and researchers working in the field. The webinar series will provide four webinars in 2020 and an additional two webinars in 2021, covering the basics of beaver restoration and continuing through implementation challenges and ways to encourage beaver restoration projects. 

There were four webinars in 2020 and more coming soon. Here the four from last year, each one is worth your time.

Webinar #1: The History of Beaver and the Ecosystem Services They Provide

PRESENTERS

  • Kent Sorenson, Habitat Restoration Biologist, Utah Division of Wildlife Resources
  • Amy Chadwick, Lead Ecologist, Great West Engineering

This first webinar in the Association of State Wetland Managers (ASWM) and Bureau of Land Management (BLM) co-hosted six-part webinar series on beaver restoration provided the historical background of beaver on the land and the impacts from loss of beaver (through various hunting, trapping and removal activities) in terms of hydrology. The webinar shared what valley bottoms can be with restoration of hydrology and the role that beavers and beaver dam analogs (BDAs) can play in that restoration. The webinar explained the Stage Zero concept and unpack the challenges created by common practices that have been restoring streams to their first point of failure.

Webinar #2: Identifying Where to Place Beavers and When to Use Beaver Mimicry for Low Tech Restoration in the Arid West

PRESENTER

  • Joe Wheaton, Associate Professor, Utah State University 

This second webinar in the ASWM-BLM Beaver Restoration Webinar Series focused on making decisions about where beaver restoration and/or the use of beaver dam analogs (BDA) can have the greatest positive and least negative impacts. Understanding that beaver restoration is not well-suited for all contexts and purposes, this webinar discussed risk assessment and introduce participants to the primary elements required to assess the efficacy of beaver projects for specific watersheds and sites. The webinar covered how data can be used to make decisions about different kinds of flow devices and when beaver mimicry/BDAs make more sense. The webinar included a demonstration of Utah State University’s Beaver Restoration Assessment Tool (BRAT), a model that helps planners assess key parameters (such as human interaction, hydrological setting, etc.) essential to beaver work. The webinar ended with discussion about the importance of post-construction monitoring.

Webinar #3: Case Studies of Long-term Changes from Beaver Restoration Activities

PRESENTERS

• Ellen Wohl, Colorado State University 
• Nick Bouwes, Utah State University 

This third webinar in the ASWM-BLM Beaver Restoration Webinar Series focused on the long-term changes in riverscapes that result from beaver restoration.  Where intense stream restoration is needed, people are identifying low-tech process-based methods that combine the management of grazing, beaver and other approaches that engage processes to create self-sustaining solutions.  Understanding the dynamic nature of these systems is important to understanding where and how they can be useful.  The webinar shared case studies of work completed, focusing on the use of beaver to restore riverscapes.

Webinar #4: Addressing Common Barriers and Objections to Beaver Restoration Work

PRESENTERS

  • Wally MacFarlane, Utah State University
    Justin Jimenez, Bureau of Land Management

This fourth webinar in the ASWM-BLM Beaver Restoration Webinar Series focused on common barriers to beaver restoration and beaver dam analog (BDA) work and when/how these barriers can be overcome. Common local landowner concerns include the taking of water from downstream water users, the potential for infrastructure damage, and a general intolerance for dam building activities. Common barriers to project success include long delays associated with the NEPA process and inability to sustain strong, diverse and long-lasting project partners. This webinar provided case studies from Utah and Idaho and will provide insights on best management practices for successful beaver restoration and BDA work.

That should keep you busy for this week. And convince you to sign up for Workshop 5 which is next week.

Webinar #5: Coalition Building for Beaver Based Stream and Wetland Restoration Success

PRESENTERS

  • Chris Jordan, NOAA’s Northwest Fisheries Science Center
    Alexa Whipple, Methow Beaver Project
    Natalie Arroyo

This fifth webinar in the ASWM-BLM Beaver Restoration Webinar Series focuses on how coalition building is essential to advancing the practice of process-based stream and floodplain restoration by helping the regulatory environment be responsive to the evolving understanding around functioning, intact riverscapes. Intentional and inclusive outreach efforts and creative partnerships are critical to achieving positive restoration outcomes. Restoring floodplains based on mimicking beaver dam inundated wetlands and their inherent complexity is a paradigm shift for the stream and wetland restoration community. Practitioners are eager to engage and the science community has jumped in to lead on methods for restoration, evaluation, and assessment. However, the regulatory community, both the formal statutory authority content and the interpretation of these regulations to allow on-the-ground restoration actions, has not seen the same degree of development. As such, a growing gap between natural process-based restoration methods and the legal authority for their implementation threatens to stall the vital progress science-based stream restoration is making. Cultural change is necessary to bridge this gap and generate the required broad understanding and adoption of novel best practices. Only through inclusive coalitions building will it be possible to develop commonly held values around functioning, process-based, vibrant ecosystems that support the natural and human ecologies essential for resilient ecosystems.


I would say that the beaver summit keeps looking better and better, but you probably would think I’m exaggerating anyway. I’m getting excited for the way it is unfurling though and I’m pretty happy with the team of beaver champions putting it together. Fingers crossed the website and logo will launch this Sunday. But here’s a preview.

And now there’s time for my favorite kind of story from Canada. This from the town of Aurora which is just across the water from New York.

Town suspends beaver trapping following public outcry

The Town of Aurora has suspended the trapping of beavers at stormwater management ponds following a public outcry.

According to Eliza Bennett, Acting Manager of Corporate Communications for the Town of Aurora, the Town has suspended trapping activity pending consultation with Ontario’s Ministry of Natural Resources about “best practices and alternative methods for beaver management.”

“Our preference is always to have peaceful co-existence with local wildlife, and we are hopeful that we can find a way to protect residents from flooding and enhance our handling of wildlife at the same time.”

Yes I’d prefer that too. Remember the homebase of Fur-bearer Defenders is right there in Toronto so I’m pretty sure the city has faced this kind of  opposition before.

“I have heard from numerous nature walkers that the Town is setting wildlife traps in ponds to kill beavers,” she said. “These lethal traps are hidden in the water at the end of wildlife trails. Check out reports from dog owners across the country whose pets suffered broken muzzles and leg amputations after stepping on a concealed trap in the water.

“There is no law that requires public posting of the location of these cruel traps, but we expect Town policy of transparency. Let us know the location of these traps and why they are necessary. Aurorans take pride in the natural trails and forests. Killing wildlife should be the last resort.”

Apparently they got the full social media treatment and came with their talking points ready.

“We have a healthy beaver population in our Town, and our preference is always for co-existence, tolerance and prevention,” said Ms. Bennett. “We actually use a number of methods to manage beavers, including wrapping trees with wire, planting species of trees that beavers don’t touch, and removing dams where necessary. That being said, in some cases, and despite our best preventative efforts, beaver activity results in a risk to public safety, or a risk of damage to public infrastructure.”

Ahhh the famous danger to infrastructure. Which might mean a tree falling on a picnic table or a culvert getting plugged. It’s a pretty adaptable defense.

“As such, for this type of situation, we operate a nuisance beaver program that includes trapping – a common practice in municipalities across North America. This is, again, a last resort. Trapping is done with licensed trappers and in accordance with the Ontario Ministry of Natural Resources and Forestry and the Fish and Wildlife Conservation Act. We work closely with these bodies to make sure that the program is run within regulations.”

The trap in question, she added, was subsequently stolen.

Well, sure.


Well you have a happy little Heidi this morning, Yesterday Georgia covered America in blue paint, the beaver summit conference found out Michael Pollock will be the keynote speaker and the schedule of both days fell into place. Let’s celebrate with some fucking great beaver news shall we?

At Asylum Lake Preserve in Kalamazoo, humans work to outsmart beavers — a welcome nuisance

Across Parkview Avenue from Western Michigan University’s college of engineering, a   group of industrious engineers is hard at work in the university’s Asylum Lake Preserve. Their ingenious creations have left some observers in awe. Others cringe at the litter of felled trees the workers already have created around the pristine lake.

But Tom Sauber, WMU Natural Areas Manager, says he’s supportive of the work of the family of beavers who have decided to move in, even as he works to outsmart them and limit the conflict between the animals and people who enjoy the quiet beauty of the preserve.

Oh I can already tell I’m going to LOVE this story, let me just settle in and appreciate it.

But Sauber says the family of beavers on a small bay along the lake’s south shore has left a small footprint — a few trees down, and their lodge hasn’t created any flooding damage, often associated with their dam-building habits.

“They are the most amazing ecosystem engineers,” Sauber says, “and I marvel at their building skills. We need to live in harmony with them and understand that this is their home.”

Lauri Holmes, co-chair of the Asylum Lake Preservation Association, agrees.

She recently walked the Preserve with Bill Schneider, owner of Wildtypes, the company out of Lansing that has been working to remove invasive plant species in the preserve.

“Bill is really an expert about plant ecology, and he was especially interested in the relationship of the downed trees, the work of the beavers, and the eliminating of the invasives that Wildtypes had been doing for so long,” Holmes says. “Bill was very pleased that the beavers have elected to live here. It means that the environment is healthy. He said that we should ‘revere’ them.”

Oh believe me Bill, I do! And now that we’re on the subject, you’re not so bad yourself.

 

“In order to alter their behavior of wanting to build dams, we have placed a beaver deceiver at the culvert that connects Asylum Lake with little Asylum Lake, the area they would most likely pick to build a dam,” Sauber explains.

The rectangular device allows water to easily flow through but its presence at the juncture tricks the beaver into thinking there is already a dam in place, so they refrain from building there.

Okay, well it’s not a rectangle and that’s not how it works but hey. Points for effort. And if it means beavers get to stick around a little longer you have won my vote.

To learn more about these amazing animals, Sauber recommends reading “Eager Beavers Matter” by Ben Goldfarb.

“If we don’t educate ourselves on the beavers we will never understand their rightful place in the environment.”

Oh I agree. Michigan beaver summit soon? Well done Kalamazoo. You have brightened an already translucent day. In fact, I feel a song coming on.
