MAKING ROOM FOR BEAVERS IN URBAN SPACES

heidi08 Flow Device Installed, Friends of Martinez Beavers, Mike Callahan October 15, 2019

Oooh if Martinez had beavers they surely would have felt that! 4,7 Earthquake last night centered practically under my mother’s apartment in pleasant hill. Things rolled and fell off the shelves and just in time for something we’ve ALL been waiting for.

Can’t We All Just Get A-Log? More In Mass. Seek Coexistence With Beavers

Mike Callahan is thigh-deep in scummy pond water, yanking loads of mud-covered sticks, mossy rocks and leaves from a blocked pipe in Millis.

“Welcome to the glamorous world of beaver control,” he says, holding up a branch that’s been gnawed to a sharp point. After pulling out a few more armloads of muck, he picks up a rake and begins dragging away bigger loads of debris.

We knew this was coming since the instagram photo a while back, but I didn’t expect it to be THIS good or this long! Ben even gets a short statement! It’s funny because I’ve just been working on my urban beaver benefits quote page so I’m wishing he had mentioned microclimates and impermeable surface but this is plenty to enjoy.

Beaver control is big business. Since starting Beaver Solutions in 2000, Callahan says he’s installed close to 1,600 of these devices — almost all in Massachusetts — and still, the calls from prospective clients keep coming in. That’s because beavers are a constant headache for many Massachusetts homeowners, chewing down trees and building dams that flood basements and roadways. But beavers also do a lot of good things for the environment, like creating habitats and purifying water. So instead of the traditional method of dealing with beavers — trapping and killing them — a growing number of people are trying for peaceful coexistence.

“There are a lot of people out there who don’t necessarily view beavers as being beneficial. They think of them as pests and nuisances and destructive animals,” says Ben Goldfarb, author of “Eager: The Surprising, Secret Life of Beavers and Why They Matter.”

But as more people recognize the benefits of having beavers around, he says, “The idea of nonlethal control is catching on across the country.”

Whooo hoo! Big business! It’s a beaver pallooza!

Beavers are what biologists call a “keystone species.” The term comes from architecture, where the keystone is the apex piece of an arch. It’s what gives the structure strength and holds it together. Remove it, and the arch crumbles.

In nature, keystone species are essential to ecosystem health. And when it comes to beavers, their contribution begins with what they’re most famous for: chewing wood. After they gnaw logs and branches with their self-sharpening front teeth, they use the material to build their homes — called lodges — and dams, to create wetlands.

On land, beavers are slow, clumsy and vulnerable to predators. But they’re fast swimmers, so in the water, they’re much safer from coyotes, bears or anything else trying to eat them. (Fun facts: Beavers can hold their breath underwater for up to 15 minutes. They also have a second pair of lips that they can close behind their teeth, allowing them to chew or carry wood underwater without drowning.)

Beavers engineer wetlands for their own protection, but these watery landscapes have big benefits for everything else living nearby, even humans.

Go look at the site an enjoy this great work for your very own. It even mentions the upcoming beaverCon 2020! Great job Mike Callahan and host Miriam Wasser! Beavers are happy to hear it!

NEVER SAY NEVER

heidi08 Beaver Rehabilitation, Mike Callahan, Who's saving beavers now? March 29, 2019

Regular readers of this website might remember the story of Nevers park in Connecticut, where there was a plan trap the beavers once the freeze unfroze. There was ample outcry on the ground and I thought there might be enough public support to change the outcome. This morning I read this from Steve of Ct.

Some local success in South Windsor, CT. After promising not to, our head of parks had traps set for our beavers in a local park. Someone posted that on Facebook, I snagged a town council member on the way to their meeting, after which the mayor called me at home and we talked. This morning he called again to say the traps were being removed and he was calling Mike Callahan to schedule an assessment. Not a bad way to start the day!!!

And thus begins another urban beaver success story, only this time they only had to call in the expert from 30 miles away not 3000. The joys of living on the east coast eh? I sense great things for the beavers in Nevers Park. Good luck team, you are in great hands.

I also received a worried message message from our beaver-watching buddies in North Carolina in Pokeberry Creek, Apparently one of the yearlings hasn’t been using his right front paw and they are wondering whether to involve a rehabber.

Yup it definitely looks like its hurting. I’m asking some rehab friends for advice. But it’s a big deal to trap and take it to be treated, and my friend Lisa reminds me that casting is really hard with an aquatic animal. Since its a front paw on a beaver – and not all that important – I’d be inclined to make sure it has plenty of food within swimming distance and wait. But what do I know so we’re asking the experts.

Meanwhile there’s strangely beautiful story out of Utah.

School Board approves wetland, bike trail project near Jeremy Ranch Elementary

The land around Jeremy Ranch Elementary School will be getting a makeover in a few months as Summit County plans for a major construction project.

To accompany two roundabouts the county plans to construct in the spring, it will be restoring the wetlands around the elementary school and building a bike path for students. The Park City Board of Education approved the county’s Wetland Mitigation Plan and easements to create a new trail at its meeting last week.

Wonderful! Wetlands, elementary school, bike path, sounds perfect. What’s the weird part?

According to the county’s mitigation plans, it intends to reroute Toll Creek east of the culvert into a new channel. The county will then install beaver dams and berms and plant willow cuttings to slow down the stream so the wetlands can re-form. The idea is that flora and fauna that left the area when the wetlands dried up will return, Hauber said at the meeting.

“For the school, it gives an opportunity for outdoor science because they can go out and actually see a wetland,” Hauber said.

Bay-State Madness

Winds picked up again last night and there were more evacuations in Santa Rosa. The death toll now is 40. Things slowed a little in Napa and the Atlas fire, where it all started, is now 50% contained. Here in Martinez the air was actually pleasant enough to risk going outside for a bit. Allowing us to see the fine layer of ash all over our deck furniture. The red flag warning for fire conditions in Napa will continue until the afternoon.

In the meantime I am happy to be catching up on some actual beaver news. The next installment will be an old favorite as poor Massachusetts struggles to eliminate the will of those pesky voters once again.

Massachusetts May Centralize Beaver Population Control

A slew of hunting and wildlife-related bills are under consideration this legislative session in Massachusetts, including one that would transfer control of the state’s beaver population to the state division of fisheries and wildlife.

Last month, the state’s environmental committee, which is chaired by Rep. Smitty Pignatelli from Berkshire and Sen. Anne Gobi from Worcester, took a look at close to two dozen acts addressing everything from crossbows to beaver traps. Dave Wattles, the black bear and furbearer biologist with the Massachusetts division of fisheries and wildlife, says wildlife-related bills tend to come up in the legislature on a somewhat annual basis.

Currently, local governments have the authority to regulate beaver trapping and determine if an emergency permit should be issued to eliminate an animal. But Wattles says the data on how many beavers are trapped through the permits is inconsistent, which makes gauging the population size difficult.

“Right now, we are handicapped in terms of our ability to [manage the population],” he says. “So giving us, at a minimum, that reporting, or giving us regulatory authority over it would enable us to manage the population to the best of our ability.”

The terrifying thing is that I actually recognize Ann Gobi’s name because she’s been hurling herself at this legislation for so many years. There are parts of this that actually make sense. It would be helpful to know some actual data about the beaver population rather than just make wild accusations saying that it has exploded. But I don’t understand why you’re saying this is going to come by counting the number of beavers killed? How would you possibly infer the number of living beavers from the number of dead beavers statistic? I mean we don’t say there were 365 deaths by gunshot in America this year so our population must be around 323,000,000 right?

I can already see that you’ll go back in time before the 1996 change and say “We used to trap 50% of our beaver population at a rate of 500 beavers a year.” (Never mind that you didn’t actually have population numbers back then either. I’m sure it felt like 50%) “And now we have issued 1000 permits so that means our population has quadrupled!”

Mike Callahan says that there is a provision in this change to include an actual beaver census. Which would be a very good thing if it actually happened. In the meantime they are talking about all kinds of sporty environmental changes.

And while the state is looking to assert more oversight over the beavers, a separate bill aims to increase the freedoms afforded to hunters. Massachusetts is one of 11 states that bans or restricts hunting on Sundays, but the legislature is looking to repeal that Puritan-era “blue law.” A number of past efforts have been mounted to do so, and those backing the current rollback want the state’s division of fisheries and wildlife to regulate the practice. Advocates who support the ban, however, say it should be preserved for families looking to spend time outside.

Also on the agenda is a proposal to allow hunters to use crossbows, which are currently prohibited by the state, except for people with a disability that prohibits them from using other archery equipment. If passed, the new law would allow hunters to carry equipment complying with specific weight and design requirements.

Gobi told the Telegram she was optimistic that the crossbow bill would diversify the population of archers, which would no longer be limited to those strong enough to pull back a traditional bow.

“I don’t know of a single instance involving a bow hunter during archery season when someone was hurt in the woods,” Gobi said. “I take my dog for a walk in the woods every day…and we’ve never had a problem.”

Oh well then, I guess it’s safe. I mean if it never happened to you personally it must never happen right? And it’s not like your state is the most populated in New England or anything, or the third most densely populated in the nation, so I’m sure carrying around crossbow or shooting on Sundays won’t cause any problems for folks. Right?

Honestly, that is the stupidest thing I have read in a long time. And you think adding crossbows is going to diversify the hunting population? I can’t understand why you think that’s a persuasive argument that makes sense. I suppose handing crossbows out to terrorists or hungry children would diversify it too. Is that really the goal?

I’m not the only one who thinks this is crazy. Here’s a nice letter to the editor this morning on the subject.

Letter: Let hunters go out on Saturdays, leave Sundays to non-hunters

Managing beavers and other wildlife doesn’t mean that we need to open up the state to fur trapping and Sunday hunting (“Bills introduced would allow hunting on Sunday,” Tuesday 10/10).

Sen. Gobi contends that some sportsmen don’t get licenses because they can only hunt on weekends. As a working mother, the only time my family gets to enjoy the outdoors together is on weekends as well. If hunters are given one day during the weekend to enjoy their recreation I think it’s only fair that families also have one day to take their dogs and little ones out in nature without worrying about wearing orange, explaining gunshots, or coming across hunted or trapped animals.

We enjoy seeing animals in their natural habitats, including beavers, which are an important keystone species. As expert engineers, they create habitat for other species and help improve water quality.

For those rare situations when humans and beavers come into conflict, there are plenty of humane, non-lethal, and cost effective solutions such as trunk guards, sanded paint, and fencing around tress as well as piping systems, fencing systems, and flow devices.

Trapping beavers is a temporary solution, removing one beaver from a desirable area only opens up that habitat for the next migrating beaver to occupy. In these instances, the trapping and killing of beavers must be repeated, ad nauseam.

Rather than trapping and killing beavers over and over again, as Sen. Gobi and others advocate, let’s pursue and continue to invent creative and humane solutions.

Margaret Mulcahy

Excellently said, Margaret. You made so many excellent points in such a short space that I am happy to share your letter. And you did it all while being much more polite than I was. Of course Ms. Gobi won’t change her position, because obviously her opinions aren’t vulnerable to actual facts or the concerns of voters or anything. But I am proud of you, and beavers unanimously agree.

I question his veracity, your honor.

After 10 years on the beaver beat you think you’ve seen it all. You get a little jaded. There’s nothing new under the sun you say to yourself. But sometimes you have to admit that it’s time to admit the truth. It’s time to quote Lily Tomlin again.

“No matter how cynical you get, it is impossible to keep up.”

Take this article from Massachusetts for example, where a forest manager has been explaining his continual removal of beaver dams because the property should be classified as agriculture. You know, I grow trees! The headline says it all. It means I’m going to keep looking for information until someone tells me what I want to hear.

More research needed to control beaver

A request by John Mirick to continue to work to maintain existing water levels and flow on his Chapter 61 property, and clean, clear and restore existing manmade and natural management system for ongoing agricultural commodities, raised lengthy discussion among conservation commission members at their June 20 meeting.

The DEP advised the commission of a beaver dam breaching on the property. Commissioners visited the site in April and learned that sticks had been taken out of the spillway and were piled up in a field and eventually burned to maintain the natural flow of the brook. Beavers have constructed two additional dams on the brook.

“We have to come to a determination about what activities are permissible in the stream within the Wetlands Act,” said commission chairman Brian Keevan.

The property has been in the Forestry Program since the 1970s. The beavers moved into the stream in 2008 and property owner John Mirick has kept the spillway open since then by removing some of the sticks. An enforcement action was issued to put a time frame on the project and give Mirick time to file a notice of intent to manage the water levels or ask for a request for determination.

Mirick said he’d talked with Peter Mirick from Mass Fish & Wildlife and was told that forestry is agriculture and he could maintain the water channel to keep it open. About once a week we pull out sticks and once a year burn them, he said. It seems to me it falls under the regulations to maintain the area for agricultural use, to restore or maintain a man-made water system, and to maintain the flow on existing waterways, he said. “So it appeared to me to be exempt under the regulations. We’re just trying to maintain the water level, not lower it,” said Mirick. “If the water backs up it saturates the soil and kills the trees.”

“Breaching a beaver dam isn’t allowed,” said Commissioner John Vieira. He said there are devices that can be used to control water level when beavers are present. “We’ve been asked to look into this and render a decision,” said Vieira. When beaver activity has created a public safety problem there is a process you have to go through, he added. They can be trapped and the board of health is usually contacted and they work with the commission, said Vieira. Breaching a dam changes the hydrology of the surrounding area so it’s considered an alteration, he said.

I didn’t destroy the building your honor, I just took out some of the concrete and a few of the girders, the rest fell down on it’s own! At least Commissioner Vieira has hear of flow devices before and knows this problem has a solution. I believe this particular forest is a whopping 2 hour drive from Mike Callahan and beaver solutions. You would think the word had trickled down by now. Apparently Mirick will keep right on searching for answers until he finds the one that tells him to keep doing exactly the same thing over and over.

I realize I’m not being very patient here. But this man is arguably in the best place for solving beaver problems in the entire country, if not the world. And not only has he not gone to see Mike or bought the DVD or talked to a neighbor, he hasn’t even cracked open a website to read about it. Just a reminder the the city of Martinez brought in an expert from Vermont because everyone in our town 3000 miles away had done their homework and read about the solutions in 2007.

And we’re not exactly a university town, if you take my meaning.

More confusion from this article posted yesterday about famed photographer Rick Price of Canada. It’s quite a nice article about how he captures wildlife in their element, but it has one photo of a beaver I cannot comprehend. Maybe you can help me?

Hungry bears and busy beavers: Alberta photographer captures animals in their elements

This is a busy time of year for Alberta’s wild animals as they emerge after the long winter — even if we don’t get to see most of the action. But with skill, patience and some long lenses, nature photographer Rick Price recently snapped these great shots of beavers in Hinton and bears in the mountain parks.

“The trick to beaver sightings is that they are only out at extreme dawn and dusk, and the other 95 per cent of the day you won’t see them,” he said.

Okay, there are lots of photos like the one above that we totally recognize and understand but then there’s the one I can’t get my head around. It honestly doesn’t even really look real. The caption says “don’t be fooled by this the fuzzy appearance, this is a ferocious rodent”. But honestly what puzzles me isn’t the ferocious part, or the larger bottom teeth, it’s the fact that those sets of teeth are two different colors.

Now we are taught that beaver teeth turn orange from the iron in their diet, and kit teeth are white until they eat enough solid food. But does this mean that all beavers only eat with their bottom teeth? Or that this particular beaver only eats with his bottom teeth? Jon doesn’t think the top incisors even look like teeth.

Has the evil hand of photoshop has played a part?

You, tell me. I don’t know. I just am well aware that it’s not what anyone would expect. Remember we have one shot of upper and lower teeth from our good friend Sylvie, and I believe they were all the same color. So is this a fake? Or a freak?

Why is it that folks in the county library complain about having nothing to read? I guess for the same reason your teenager opens the fridge and says there’s nothing to eat. Certainly the state of New York has blinders on when it comes to solving beaver problems, other wise they would have called on Beavers: Wetlands and Wildlife years ago. The answer to their question is a whopping 130 miles away.

Spencer Trying to Fix Nuisance Beaver Problem in Nichols Pond

As the Spencer Village Board of Trustees continues to ponder the beaver problem that has been plaguing Nichols Pond, they sought input from expert Scott MacDonald, who has had to deal with the industrious critters in his capacity as executive director of the Waterman Conservation Education Center in Appalachin.

For years MacDonald has been trying to figure out the best way to curb damage by the beaver population at Brick Pond in Owego. He found an effective method, though it involved installing two bulkheads that control the water level at a cost of $80,000 taxpayers’ dollars. The Spencer Village Board is seeking a more cost-effective way to prevent damage in and around the village-owned pond.

MacDonald agreed that it was also probably a beaver that chewed through the underwater electrical line that powers the fountain in the center of the pond. Goodrich said he’s not sure whether or not the fountain will be repaired in time to turn it on this summer.

I want to meet the man who sold them the 80,000 dollar solution, because he’s a genius and should work for the federal government. Clearly no kind of flow device or beaver deceiver was ever installed because they have a crew of volunteers pulling out debris on a daily basis.

The handful of volunteers who clean the debris out of the pond’s culverts are becoming fed up, according to Goodrich. “They want to move onto other stuff,” he said of the volunteers, “but they’re so busy with the beavers they can’t do anything else.”

“I don’t blame them,” he added,” because they’re out there every day.” He said that most if not all of the volunteers are older and that the physical labor of clearing out sticks and packed mud can be hard on them.

Therefore, Goodrich said, the board needs to come up with a solution sooner rather than later. The beavers cannot be trapped and relocated because they are considered a “nuisance” species in New York State, the logic being that it’s not fair for people to release beavers elsewhere and pass on the burden to other landowners.

Goodrich said that he is not opposed to having the beavers killed, a resolution that none of the other trustees were very enthusiastic about supporting.

Most of the trustees said they believe that if the beavers are killed another family of beavers will move in. Goodrich argued that trapping the beavers that live in the pond currently would at least give the village time to come up with an adequate solution before new ones decide to make the pond their home.

MacDonald said he considers having the family beavers killed the one “black mark” on his record as caretaker for the pond, even though it was necessary to secure the state funding necessary to save the pond after the flood.

“It was very bad,” he said. “The public got very upset about it.”

We learned so much from that incident. We still don’t have a clue how to solve beaver beaver problems.

Since that time, he has learned how to raise and lower water levels at certain parts of the pond. If he pays attention to what the beavers are up to, he can often dissuade them from building in problematic places because beavers won’t build dams where the water is not deep enough for them to float the big logs they need to start their shelter. Beavers, he told the board, do not like to drag heavy logs.

Even with the bulkheads, MacDonald said there is some manual labor involved. There’s one culvert he has to dig out himself every once in a while or it becomes a major project — over the last winter he let it go too long, he said, and a few weeks ago he had to go out in a wetsuit with a backhoe to clear the stopped-up water flow.

Some level of manual labor seems inevitable if the beavers are to stay, but Spencer Village Trustee Nicole O’Connell-Avery said that she disapproves of setting kill traps.

She said the traps would likely be set underwater and would catch the beavers by the leg, holding them until they drown. She said it sounds like an awful way to die, and questioned whether or not the traps could endanger swimmers, pets or boaters who fall overboard.

O’Connell-Avery was enthusiastic about the idea of installing heavy-duty fencing in strategic areas that would prevent the beavers from building at the pond’s intakes and outtakes. Mayor Christine Lester said she thought this was worth a try.

O’Connell-Avery also offered up the unique but untested idea of population control: catching, neutering and releasing the pond’s male beavers. O’Connell-Avery works at Cornell University, and she said she would ask around to see if her colleagues would be interested in using the pond as a case study.

Beavers live in families of eight to 10, and usually only one family will live in a body of water as small as Nichols Pond. When the family has about eight offspring, the parents kick out the two oldest, who then seek new habitats at neighboring ponds, according to MacDonald. O”Connell-Avery said that this structured family setup might make for an ideal situation in which researchers could trap the males and keep track of the results.

When the family has about EIGHT OFF SPRING THEY KICK OUT THE TWO OLDEST? Really? And you work at Cornell? Are you the frickin’ janitor?

Good lord this riles me. I’m too old for this sort of nonsense. Considering that Cornell already HIRED Mike Callahan to install a flow device, every one of these folks should know better. That was just over an entire year ago, I guess I can understand why you wouldn’t be up on such ancient history.

I guarantee you Mike didn’t charge the university 80,000 dollars for his installation, by the way. Heck even when we brought Skip Lisle 3000 miles out from VERMONT to solve our problem it didn’t cost us 80,000.

ACK! Someone get me a paper bag to breathe into. The Cornell website tells me that Nicole is a supervising vet Tech at the wildlife animal hospital at the university. She could really make this happen. We can only hope that before she picks up the scapel to neuter these beavers she cracks open a book and reads that beavers enter estrus once a year and young disperse at two years regardless of the family size. Surely she will listen to a reasonable argument?

Given Spencer’s track record so far, I’m not counting on it.

I need to calm myself by sharing the beautiful new sign that arrived yesterday for my beaver booth. Isn’t this lovely? It will hang out from my booth like one of those Ye Olde Shoppe signs!
