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

Tag: Mike Callahan


A few days ago this aired on CBC radio -. the middle segment is about installing fish passage boxes so that salmon could get over beaver dams in Nova Scotia . Victoria Neville does a pretty delicate job with the interview trying tp explain all the good beavers do. but it still dumbfounded me that the WWF would be using donations to fix a problem that doesn’t exist.

Of course I said as much at the time which prompted several very concerned and patient conversations about  public perception being so abysmal in the region they are working hard to chip away at the edges. The design was Adrien’s based on Mike’s and they made things easier for fish at low flow conditions which climate change was making happen more often.

I listened and underestood some of it. But honestly if the problem is mostly PERCEPTION then wouldn’t it be a mistake to offer a solution that reinforces the idea that there us a problem in the first place?

I suggested at least changing the name to something that reminded people that  under normal conditions it wasn’t needed. 

Something like the “Drought Ladder.”

 


By all accounts yesterday was a splendid beaver day, with presenters from around the world really swinging the bat hard for beavers. To the right is Frances Backhouse posing with conference organizers Scott McGill and Mike Callahan (in disguise). Here are some highlights from yesterday Sharon and Owen Brown of Beavers: Wetlands and Wildlifeand were presented with the lifetime achievement award, Skip did a very well received presentation on the history of the beaver deceiver (summarized by Malcolm Kenton) and here’s a brief run through of what I’ll be presenting today.

The only mess-up of the day is that Emily Fairfax didn’t get time to present her awesome fire dissertation – It was a packed schedule and either things started late after lunch or James Wallace couldn’t squeeze her in – but she was hoping to be able to say something about it last night and in her connections with people She was a good sport of course and Lord knows we’ll be hearing from her again soon!

Check out these great notes by Malcolm on Skip’s Presentation, Worth A Dam’s Emsissary Doug Noble said he stole the show.

Skip Lisle, inventor of the “Beaver Deceiver,” speaking at #BeaverCON2020:
– The Beaver Deceiver is a flow device, but not all flow devices are beaver deceivers!
– We’re like moose — we like wetlands and we know where to turn to make healthy, productive ecosystems. We need to develop a common language & history.
– We’re lucky to live at a time when there are tremendous opportunities to save society a great deal of money with creative long-term remedies and create tremendous habitats.
– There’s a lot of pushback out there because people are used to wetland areas being drained – the culture associates wetlands/swamps with stagnation, disease, “wasted land” and various unpleasantness. So many places inefficiently keep killing beavers in the same places over and over again.
– In my career at the Penobscot Nation, my friend and I kept trying and building junky flow devices until we came up with the successful trapezoidal concept. The trapezoid had to get larger because they’re attached to the dam. Dam-leak separation makes a flow device more robust. Though they’re smart, beavers don’t do much deductive reasoning and can’t grasp the hollowness of a pipe.
– There’s a lot of controversy about where flow devices can work, but I don’t have any problem with zero inches/feet of water. A dry flow device can do a great job protecting beaver habitat upstream. Getting people to stop killing beavers is another issue — there are wide-open trapping seasons in most of these places.
– Every site is different so I need to put in a lot of thought as to what device best suits the place. Some culvert protectors need floors and some don’t.
– We’ve done enormous damage to wetlands after draining them, but beavers can repair all that if we just stop killing them. One beaver in one month (before moving on) brought so many birds to a site I worked on that weren’t there before. It’s miraculous! Remarkable wildlife viewing spots can be created in very short order. Every town can do this.
– I build simple wood structures to guide beavers’ damming — I don’t use the term “beaver dam analog” because it doesn’t need to look like a beaver dam to get them started.
– You can have a long beaver dam parallel to a road and have the water level much higher than the road, with a few pipes through the dam and under the road, and the road stays dry.
– There’s also an aesthetic and spiritual value to keeping beavers on the land — they’re dynamic, fascinating and all different. They bring a lot of joy to our lives.

Great news coming out of Rhode Island where both our friends Mike Callahan and Ben Goldfarb helped find a sweet end to a beaver complication.

Beavers Continue Their Rhode Island Comeback

Rocky Mountains

CUMBERLAND, R.I. — At the Cumberland Land Trust’s nature preserve on Nate Whipple Highway, beavers created numerous dams on East Sneech Brook in the years after their arrival in 2014, flooding the property and forcing the organization to detour its hiking trail and build a boardwalk over the wettest areas.

Worse, the flooding killed many trees in the Atlantic white cedar swamp, a rare habitat found at just a few sites in Rhode Island.It’s a sign that beavers are continuing their comeback in Rhode Island, after being extirpated from the region about 300 years ago.

When the white cedar trees began to die, the land trust took action to address the situation. They hired a Massachusetts beaver-control expert to advise them on how to install a series of water-flow devices — a combination of wire fencing and plastic pipes going through the beaver dam that tricks beavers into thinking their dam is still working but which allows the water to flow down the stream unhindered.

Hurray for Mike! Hurray for the Cumberland land Trust! Just because Rhode Island has the word ‘Island’ in its name doesn’t mean you are going to avoid beavers. You get what we all get. And its good to know you understand how to cope.

According to Ben Goldfarb, author of the award-winning 2018 book Eager: The Surprising, Secret Lives of Beavers and Why They Matter, beaver ponds also help to recharge aquifers, dissipate floods, filter pollutants, and ease the impact of wildfires. A 2011 report he highlighted estimated that restoring beavers to one river basin in Utah would provide annual benefits valued at tens of millions of dollars.

“Even acknowledging that beavers store water and sustain other creatures is insufficient,” Goldfarb wrote. “Because the truth is that beavers are nothing less than continental-scale forces of nature, in large part responsible for sculpting the land upon which we Americans built our towns and raised our food. Beavers shaped North America’s ecosystems, its human history, its geology. They whittled our world, and they could again — if, that is, we treat them as allies instead of adversaries.”

“Great blue herons gravitate toward newly flooded areas with dead standing trees,” Brown said. “But beaver ponds aren’t perpetual. They come and they go. Beavers create a dynamic state of change that can benefit a lot of things.”

Yes, yes they do. Including humans. I’m so glad you could see the forest for the [cedar] trees and make the right decision. You are a Land Trust after all, that should include wetlands and wildlife right?

There’s time for a little bit more good news right? I mean both its a little big of news and a little bit good, Well we are grading on a curve. And its USDA, So I’m pretty sure its good.

Helping beavers move to the suburbs

Nick Kaczor, CWB, an assistant manager at the Rocky Mountain Arsenal National Wildlife Refuge, met with Wildlife Services in Colorado to explain that the arsenal was going to try to re-establish a local beaver population. The refuge management plans include promoting a native population of American beavers (Castor canadensis), which would aid in restoration of a stream.

At the same time, another cooperator was requesting relief from damage caused by beaver on a suburban property in southern Douglas County.

The Rocky Mountain Arsenal National Wildlife Refuge, a 15,000-acre urban wildlife refuge just north of Denver, seeks to conserve and enhance populations of plants, fish and wildlife and to provide compatible public uses. Over time this land has transitioned through a variety of uses, first from prairie to farmland, then to a military site in the 1940s and to a chemical production site in the 1950s. A public-private partnership carried out clean-up efforts from the 1980s through 2010, and today the site is a sanctuary for more than 330 wildlife species including bison (Bison bison), black-footed ferrets (Mustela nigripes), and burrowing owls (Athene cunicularia).

Hmmm so someone wants beavers and someone wants to get rid of beavers. Wait, don’t tell me,I know how this ends.

Under a permit from Colorado Parks and Wildlife, Wildlife Services-Colorado used suitcase traps to capture five beaver causing damage elsewhere. They were trapped during the summer months until mid-September in order to relocate them when they were old enough to survive on their own and find adequate habitat before winter.

They were released on the refuge at sites where staff provided fresh-cut trees for temporary forage and shelter. Refuge staff will continually monitor the sites, while also protecting bald eagle (Haliaeetus leucocephalus) nest trees from beaver damage.

Wildlife Services-Colorado appreciated this opportunity to support a localized recovery effort and the recognition we received for it from the Colorado Trappers and Predator Hunters Convention. We look forward to finding more beaver that are looking for a suburban Denver lifestyle.


Time for an article you are going to love. It’s so good I didn’t want to squeeze it in yesterday. It needs it’s own hallowed space and attention. This is from Connecticut where our good friend Steve Straight has been hard at work making sure the next beavers that come along have a better end,

Beavers are blamed for fallen trees and flooding, and authorities are euthanizing them. Is there a better way to fix the problem?

Last month, South Windsor officials trapped three beavers and had them euthanized. The beavers had caused safety issues at a town park by gnawing on trees near the trail system, which blocked a spillway to a pond and caused flooding issues.

The trapping and killing of the beavers, one of nature’s most industrious mammals, sparked outrage among residents, with some calling for more humane treatment. State officials say they have managed Connecticut’s beaver population this way for decades. But critics say there’s a less drastic, more cost-effective manner to deal with beavers.

He said a solution could have cost the town about $2,000, and volunteers, such as local scout troops, could have helped to wrap the trees. Straight hired Mike Callahan to investigate the beaver situation at Nevers Park.

You gotta love the East Coast, where you can bring in the expert from out of state for less than  a tank of gas. Unlike Martinez where we had to fly Skip 3000 miles. Well, how did it go? What did he think?

Mike Callahan of Beaver Solutions LLC said his company has resolved more than 1,500 human and beaver conflicts since 1998 by using flow devices, such as culvert protective fences and beaver dam pipes. These methods allow the water to flow out of the pond created by beavers, in turn reducing flooding.

“In my experience, flow devices are the best beaver management method for approximately 75 percent of human-beaver conflicts. Where feasible, they offer the lowest overall cost, longest reliability, lowest labor and maximum environmental benefits,” Callahan said.

Callahan said a 12-inch pipe at Nevers Park would maintain a normal flow through the spillway, even if new beavers recolonize the pond and try to dam the spillway again. He said lightweight metal fencing could have been wrapped around the larger trees to prevent them from falling on the trails.

Callahan noted it would cost the town “far less to protect trees” along the trail with fencing than it would for town workers to continue to remove them. He believes beavers may recolonize the area within a year or two.

Ahhh you heard it yourself. Beavers are coming back and there are better, cheaper ways to fix things than by killing

“Fortunately, both the flooding and the tree felling concerns can be managed in a cost-effective, long-term, environmentally friendly and humane manner,” Callahan added, “which would allow the beavers to remain in the park providing environment benefits, public enjoyment and education values.”

South Windsor resident Steve Straight, who lives near the park, opposed the trapping from the start. He said the town should have investigated nonlethal methods first and needs to come up with a long-term solution.

Environment benefits, public enjoyment and education values. Let the beavers do their job. Game point. Set. Match. And the money shot?

“Let the citizens of South Windsor enjoy these fascinating creatures as they go about their work creating a tremendous ecosystem that harms no one. Let’s be clear — the beavers are not going away. And by the way, neither am I.”

How much do we love Steve? A very very lot of much, that’s how much. The best thing a beaver protector can do is be a stone in the river, making it more trouble to continue on the wrong path than it is to correct course and start on a better way. It’s of course good for the beavers, and the environment, But also for the entire community that gets to be part of a humane solution.

This is something we in Martinez particularly understand. If you haven’t seen this in a while I would just point out this is National news with Brit Hume at the end of the clip. And the flow device is already installed, You can see it in the shot over Dave’s shoulder. it’s just that no one believes it will work so the mayor of director of public works don’t even mention it.


Deal another hand at the beaver table, because Maryland’s own Ecotone just entered the game with full pockets.   Way back in February the CEO and founder of the group, Scott McGill, joined Mike Callahan and Frances Backhouse on an exciting podcast about beavers saving the Chesapeake. remember?

Now their swanky eco-website has a whole new beaver management wing!

      

Ecological Beaver Management Solutions

The North American beaver is a keystone species whose activities promote ecological biodiversity across the landscape. Beaver dams help improve water quality by reducing sediment and nutrient flow to downstream sources, creates wetlands and enhances wildlife habitat.

Beaver activity on private and public property can become a nuisance, impact agricultural activities, flood infrastructure, and impact valuable vegetation.  In the past, trapping (killing) was the only available option to mitigate potential beaver problems.  By working with researchers and experts from around the US, we are able to offer an ecologically friendly beaver management solution by designing and installing custom flow devices (i.e. beaver deceivers) and culvert exclusion fences, providing a long term cost-effective solution. Ecotone installs flow devices to manage the size of the beaver pond, regulate water levels to desirable levels, and mitigate activity around culverts, while also keeping the dam, and the ecosystem services it provides. By working to co-exist with the beaver we can create a cascade of benefits to water quality and biodiversity. ​.

INDUSTRY PARTNERSHIP

. Ecotone has partnered with Beaver Institute – a nationally recognized nonprofit organization focused on beaver management and watershed restoration – to bring to market sustainable beaver management solutions that help resolve beaver-human conflicts and maximize the benefits beavers bring to the environment.

It’s wonderful to see the seeds of Mike Callahan’s beaver institute take root and grow into such a healthy enterprise. Beavers everywhere are thanking their lucky stars that Ecotone climbed on board, and Mike decided that being a Physicians Assisstant just wasn’t for him.NO
