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

Category: Beavers and trout


Don’t you just hate it when you have the very best fishing hole and a bunch of beavers move in saving water and trying to make it better? Building their rotten little dams that create more nutrients and generate more fish?

Yeah, me neither.

Dammed if they do, dammed if they don’t: Beavers have claimed a popular kayaking and fishing spot, and residents are not happy

Texas Pond in Oxford is officially under new management. While the new owners are longtime residents, they are pursuing a development initiative. Locals have raised concerns that such aggressive building will have a negative effect on the pond’s recreational and scenic qualities. However, construction continues unabated, as the developers are protected under Massachusetts law.

As surprising as it might be, Texas pond is about an hour away from Mike Callahan. And if people were really worried about the beaver activity there are answers a phone call away. But that’s not the issue. It’s massachusetts so we know COMPLAINING is the issue, about the law that banned trapping lo these many years ago.

“It’s like a fortress,” said longtime resident Kathy Doiron, describing the dam, “it’s ruining the pond.” The water level of the pond has fallen dramatically and residents have noticed the absence of the once-flowing current. Residents believe the enormous beaver dam to be the cause.

Doiron has lived beside Thayer Pond for over two decades and can see a difference from even five years ago, as the area becomes more swamplike. An avid kayaker, she said getting to the river requires dragging a kayak over the dam, which may soon be impossible.

Kayaking isn’t the only curtailed activity. As herbivores, beavers don’t compete with anglers for fish, but the two are traditionally at odds. Beavers are famous for slapping the water with their tails to alert the colony of possible threats and any fish are scared away — along with any hope for a decent catch.

You know how it is. You sneak down to the pond at dawn and throw in your line. And then one of those rotten overgrown rats slaps its tail at you and scares away all the fish! It’s not fair! Never mind that the fish are there to eat the things that are sustained by the pond the beaver built. Never mind that there are more fish and more diverse fish now. You can’t catch them because of those darned slappers!

“The beavers are horrible,” said John Bottcher, who fishes regularly at Thayer Pond. “The damming there is really bad. It can definitely affect fishing.” When beavers impound an area, changes to water depth and temperature can impact the type of fish there.

The beavers have always been there, Bottcher explained, but “it seems like lately they’ve been putting in extra work.” While true that beavers are a natural part of New England waterways, over the last couple of centuries, they have had an intermittent presence in Massachusetts.

You know the media spends so much time writing down the ridiculous lies inexperienced fishermen spread about beavers it’s no wonder they go to the same diners over and over to interview trump supporters about the Covid hoax. They are used to being lied to. They think its their job.

“When beavers came back, they got right back to work and found we had built in places where they like to impound water,” said Colin Novick, executive director of Greater Worcester Land Trust, leading to what he referred to as a “user conflict.” Novick makes no pretense of neutrality, saying that the landscape was initially “managed by beavers,” who are taking up their original role in the ecosystem.

From an ecological perspective, that role is vital — beavers are considered a keystone species, having an outsized benefit to the environment relative to their population. Through impoundment, they create ponds and wetlands that foster biodiversity by providing habitats for various plants and wildlife. The fallen trees make a submerged canopy that gives fish a place to hide from predators as well as potential spawning areas.

A multitude of species, including humans, benefit from the presence of wetlands, as they control flooding damage by slowing water release. Wetlands also improve water quality by removing toxic chemicals and filtering out sediment.

Colin has a clue. I’m so glad someone does.  He’s the exectutive director and deacon at the local catholic diocese. Something tells me he and Mike have crossed paths before.

For the residents of Oxford, this is all well and good except “they’re creating dry lands, not wetlands,” said Doiron, citing the drop in water level. However, not everyone believes the beavers to be the culprit.

“We are in a protracted drought and water levels are dropping where they haven’t in decades,” said Jennifer Warren-Dyment, of the Oxford Town Manager’s office, describing a level two drought, with below average rainfall and above average temperatures. State reports indicate the drought began in late June, coinciding with the water level changes in the pond.

She said neither the Town Manager nor the Department of Public Works has received any complaints about beavers.

So wait. Rather than saying to yourself WHEW! There’s a drought! Good thing beavers saved the water or otherwise there’d be no pond at all and all the fish would be DEAD. You say DAMN THOSE BEAVERS for stealing our water! What is wrong with people? I ask you.

Besides the issues with recreational use of the area, residents have voiced health concerns due to the stagnant water, namely mosquito-borne viruses such as Eastern Equine Encephalitis. However, Novick clarified that it takes a special habitat for the mosquito that carries Triple E — “a cedar swamp, which is not going to magically appear just because beavers move in.”

 
The situation at Thayer Pond reflects a larger debate about when and how wildlife should be reintroduced to an area. In the case of beavers, they are an integral part of an ecosystem that may become dysfunctional without their contribution. However, in bringing back a species, we also have to live with them, striking the balance between serving as stewards of the natural world and co-existing with it.
 
Just to be clear, these beavers weren’t reintroduced to this pond or landscape and I dare say beavers were back on the scene long before the condos were erected. The difference is that trapping has been curtailed in the time since 96 so you are having more situations that can’t be solved with a conibear.
 
Honestly, if I were you, I’d sit down by the pond for an hour. Watch the beavers, the fish, the birds and the wildlife that has grown around this pond and realize that those damn impoundments made it all possible.

I know what you’ve been thinking. The beaver news these past days has been so excellent and positive, beaver benefits are so well understood even around the world, that the tide has finally turned. Why would anyone need to fight for them any more? Clearly everyone’s on the same team now, playing for the good of the planet. You might be thinking “It’s finally over! The battle’s done and we really won! Lay down my sword, unbuckle my armor and rest my shield against the hearth. Let’s all have a jug of wine to celebrate. Because there’s no need to be a beaver warrior any more.”

But on that day, when every place in the nation and most in Canada understand the importance of beavers and values their presence on the landscape, when the people of the world can finally see the forest for the trees, and the water for the flooding —

There will still be Wisconsin.

How To Maintain Local Trout Streams? Often, It’s Through Explosives

Jeremy Irish, an assistant district supervisor with the USDA’s Wildlife Services program, triggered the blast, undoing some of this year’s construction by beavers in the area. In the process, he cleared another portion of one of northern Wisconsin’s best trout streams.

Hundreds of miles of northern Wisconsin’s best trout streams flow freely, providing excellent fish habitat and great fishing. But if beavers, and they dams they create, had their way, the landscape would be much different. Often, it’s humans like Irish who have to help strike the balance, doing it using fuses, detonations, and explosions.

“Beaver are a very unique animal. They can alter their habitat to suit themselves, and in the north here, they definitely need to do that to make it through the winter,” he said. “The difficulty is, in altering their habitat, they also create problems for other species. In this case, we’re talking about a cold water ecosystem to support brook trout populations and spawning habitat.”

Apparently the USDA has not yet released it’s ground breaking (ha) research on why trout in the state of Wisconsin would have evolved differently than the trout in every other part of the world, but apparently they have the proof. Because why else would they ever be spending all that money and time? Oh and did you know Wisconsin thinks they have more beavers now than they used to before the fur trade? And that these two species didn’t actually co-evolve because the situation got WORSE. Yup.

Maybe it’s the cheese curds.

Whatever the cause. there are clearly a few battles left to be fought in the state. There are really places that believe trout are happier with explosives in their water than with beavers. I wrote the reporter on this story yesterday and I’ll let you know i I hear anything back. But I wouldn’t put down your armor just yet.

Sure beavers are good for trout.
But are they good for ALL TROUT? In Every state? And in streams with left-handed fisherman? Well, science demands an answer. You know just because things are proven true over and over doesn’t mean they’ll be proven true again. Right?

Beavers, Trout, and a Changing Climate

Driving through the lush forests of America’s Pacific Northwest, you might spot this bumper sticker: “Beaver taught salmon how to jump.”

Instead, the bumper sticker refers to the fact that North American fish species co-evolved with the continent’s largest rodent. Salmon and trout have adapted to jump over or swim around beaver dams. In return for the extra effort navigating upstream past dammed waterways, native fish benefited from the bountiful food and shelter created by beaver ponds.

Today, though, both furry and finned creatures are facing a new “normal.” Populations of native salmonids and beavers have declined drastically due to human influence. In addition, climate change has further reduced the water quality and flows in headwaters streams where native trout reproduce. As their habitat dwindles, it may mean that fish are in trouble if certain tributaries are blocked by a natural barrier. This has sparked concerns about whether beaver dams are always in the best interest of wild trout.

See climate change might mean we need to kill more beavers! I knew there was a reason for it!

Natural and simulated beaver ponds help slow down the flow of water, providing natural water storage and flood control. The ponds recharge groundwater, which keeps streams running when rain and snowmelt are scarce. It also spreads water across the floodplain so it can grow more green plants that feed terrestrial wildlife and livestock.

Fish get to join the feast, too, since beaver ponds diversify stream habitat and produce more aquatic plants and insects. Plus, the side channels, sloughs, and meanders created by dams add complexity to stream habitats, giving fish more places to hide, rest, or spawn.

Because of these promising ecological results, beaver-related restoration projects have increased markedly over the past ten years. In fact, these projects have become so popular that their implementation has outpaced the science on how more natural and simulated beaver structures are affecting fish and other wildlife.

“We need more research on exactly how beaver ponds impact fish so we can make confident, science-based decisions moving forward,” says Lahr, who worked with Clark Fork Coalition, Lolo National Forest, and The Nature Conservancy to design and instaNotll his study.

Not so fast there Mr. Beaver. Just because your dam makes things better doesn’t mean they make things BETTER, you know? Bring on the abacus and the measuring tape so we’re sure it all still works. Science needs to count things. You know it does.

“On the whole, fish benefit from beavers and their ponds. The trick is to make sure we choose the sites wisely and make sure they benefit the whole aquatic community, including wild trout,” says Ladd Knotek, a fisheries biologist with Montana Fish Wildlife and Parks who helped tailor Lahr’s research project.

See long ago Montana killed most of its wild trout. So they helped the fisherman along by introducing some hatchery trout. But we don’t know about whether hatchery fish can manage beaver dams too. Because they are sissies and Frankensteins. So the science that has been verified a million times in a million different streams better just prove itself all again.

Knotek says that the majority of beaver-related restoration projects are not a problem for native salmonid species. However, Montana only has a few remaining streams where pure (non-hybridized) cutthroat trout, arctic grayling, and bull trout thrive. These strongholds are areas where fisheries biologists worry that new in-stream structures might unintentionally impact native trout populations because these species can no longer adapt easily to habitat changes.

“One hundred years ago, beaver dams weren’t an issue. If a dam was too high or there was no way through, the overall population was fine because the species was widespread. But we don’t have that population resiliency anymore,” explains Knotek.

Good Lord. This is so irritating it makes my head hurt. Well, maybe banging it on the keyboard does that. This article is in the frickin’ NATIONAL WILDLIFE FEDERATION BLOG. If we’re going to broadcast ridiculous drivel from NWF who should anyone even bother to maintain a informative website about beavers?

Another pressing question for fisheries biologists is whether natural or simulated beaver ponds give non-native trout a competitive advantage. Introduced species like brook, rainbow, or brown trout tend to fare better in warmer water—such as ponded habitat that heats more quickly than flowing water. That may give non-native trout an advantage in beaver ponds, allowing them to outcompete native trout for food and other resources.

“We know that beavers add habitat complexity in the stream, which increases the carrying capacity for all fish species. The question is do they disproportionately benefit non-native trout?” says Knote

What about our Frankenstein fish?  Are those icky beavers ruining things for them with all their pointy obstructions?

Instead, Lahr wonders whether beaver ponds are able to hold more fish of all species, supporting native and non-native trout equally.

“When you add beavers to the mix, models predict that westslope cutthroat trout persist and have higher growth rates because there’s more food, more plants, more water,” says Lahr.”And that translates upstream as you leave the pond, too.”

“There’s a chance that beavers may create true climate resilience for trout in Montana,” adds Lahr.

YA’ THINK?

Let’s be fair to Andrew Lahr. He may truly believe the radical notion that beavers are GOOD for fish and his thesis chair is so horrified by the outrageous claim that he is making him prove it scale by scale. I supposed you have to at least appear willing to accept disconfirming data to get your dissertation approved anywhere. But honestly, my money’s on the beavers.

Isn’t yours?


England just isn’;t sure beavers fit onto their landscape anymore, but all indications point in their favor. I don’t know what they’re expecting. A golden sword rising from the misty lake to show they belong? Maybe.

Wild beavers reduce flood risk and boost wildlife, study finds

Beavers living wild on an English river have reduced the risk of flooding for local people and boosted wildlife, a five-year trial has found.

The aquatic mammals living on the River Otter in Devon have caused some localised problems for several landowners, but these could be addressed successfully with “active management”, the study said.

Other wildlife, including fish, water voles, amphibians and birds, have benefited from the presence of the beavers living on the river and creating new habitat.

The findings are the culmination of a five-year study of the first licensed release of beavers into the wild in England since they were hunted to extinction more than 400 years ago.

It found the wild beavers on the south Devon river provided more benefits to people and the landscape than the costs they caused.

Good lord. Who among us could make the same claim. Have YOU ever solved more problems than you caused? Have I? Well I guess England is a mean judge of character. Because they’re backing this claim up with data.

Research by the team of scientists, overseen by Professor Richard Brazier from the University of Exeter, found they are providing benefits to people, including in the flood-prone community of East Budleigh.

Beavers have constructed six dams upstream of the village, which have measurably and significantly reduced peak flood flows through the community, the report said.

Evidence from another trial in north Devon, where beavers in an enclosure have built 13 dams and ponds, shows they also play a role in filtering soil, manure, slurry and fertilisers from farmland.

Despite concerns that beaver dams might affect fish populations, the research found that in the pools created by damming the streams there were 37% more fish than in comparable stretches of the river with no dams.

Get the hell out! 37% More fish in beaver ponds?  It’s almost like putting a percent sign next to an actual fact makes it sound MORE true. (4 out of 5 dentists recommend sugarless gum for their patients who chew gum sort of thing). There are more fish in beaver ponds. 37% more. We counted and did the stats. Now do you believe us?

Devon Wildlife Trust’s Mark Elliott, who leads the River Otter Beaver Trial, said “I think we’ve all been surprised by these amazing animals’ ability to thrive, once again, in our wetland ecosystems.

“It also shows their unrivaled capacity to breathe new life into our rivers and wetlands, very few of which are in good health.”

Unrivaled the right word, Mark. What they do has never been done by anyone else. Nobody does it better. No one else even comes close. Let beavers do their jobs and if you want to count up those jobs on your little clipboards go right ahead.

Excuse me. I feel a song coming on.

Lots of beaver news today. Lets focus on or friends, first! Mike Settell in Pocatello Idaho is doing another beaver count! How can it be that his volunteers look frozen but he looks young and cheerful after all these years!

Watershed Guardians to hold their 9th annual BeaverCount

On Feb. 1 and Feb. 8 Watershed Guardians will hold its 9th annual BeaverCount, a free snowshoe event to raise awareness of the important role beaver play keeping the Portneuf River watershed healthy.

On Feb. 1,  volunteers will meet at the Mink Creek Nordic Center at 10 a.m. where a training  will be held for anyone interested in counting beaver activity. The training will include winter outdoor preparedness and censusing techniques for beaver.  Participants will also learn about their watershed. This training is for newcomers and BeaverCount veterans, known as “Flattailers.” Flattailers are encouraged to attend the training to update their skills. 

Man that’s smart! I wanna be a flat-tailer! Don’t you?

Snowshoes and food will be provided by Watershed Guardians for both weekends. Participants must pre-register, which they can do on the Watershed Guardians Facebook page or at the website, www.watershedguardians.org.  Should conditions warrant on Feb. 7,  the count will be rescheduled for Feb. 15.  Please check Facebook and/or the website for updates on weather conditions during the week prior to Feb. 8. 

Watershed Guardians is a 501c (3) non-profit whose mission is to, ” Protect, maintain and restore the Portneuf River Watershed, one beaver at a time.”  Data collected from BeaverCount is used to influence management decisions with regard to trapping regulations.

Brave beaver-loving Mike has been at this work nearly as long as us. On a tougher landscape where fur-trapping abounds. Thank goodness he’s willing to snowshoe every year and share what he knows!

Let’s stop by our local Sonoma beavers next and see what they’re up to, shall we?

Bill Lynch: Frankly, my beaver, we don’t give a dam

The Sonoma Index-Tribune recently published a couple of articles about beavers and otters in Sonoma Creek (“Otters Join Beavers in Sonoma Creek,” Dec. 27).

It’s a good sign, not just because it’s nice to know that Sonoma Valley’s main waterway is actually clean enough to support wildlife, but also because beavers can actually improve life for other critters, including my favorite, rainbow trout.

Our Sonoma Valley creeks used to be home to a healthy population of steelhead/rainbow trout and spawning areas for king and Coho salmon. In my boyhood here we could fish for trout in most of our streams through the spring and early summer.

Since those days, our creeks have lost more than half of their water and many completely dry up by June and stay that way until the fall rains return.

This kills any chance for salmon fry and steelhead trout fry to survive.

I don’t understand the headline. Shouldn’t it be “We should all give a dam?” But the column is excellent! That’s what we need. A few more beaver friends argue that saving salmon and trout depends on them. Thanks Bill! Have we met?

About a year and a half ago, I visited the Scott River valley were local residents formed the Scott River Watershed Council (SRWC) and are working with Dr. Michael Pollock, eco-system analyst for National Oceanic and Atmospheric Administration (NOAA). In this little community people are doing something about bringing back their creeks.

The river, no bigger than our own Sonoma Creek, was once a prolific salmon and steelhead spawning resource, before it was ruined by past gold mining. Then climate change and other factors caused it and its tributaries to dry up during most summers.

But in 2014 SRWC began constructing “beaver dam analogues,” which are human made structures that mimic natural beaver dams, store water and create habitat for all kinds of local species, including steelhead trout and Coho salmon. Over time, these naturally appearing dams create pools where fish can survive.

Dottie and I met with Betsy Stapleton, chairman of the SRWC, who showed us some of the work her group has done on the creek. The results are impressive. They were able to preserve large areas of fresh, clean water in which Coho and trout fry are surviving. Every season, the fish count goes up.

Real beavers are helpful, but when there are not enough of them, small grassroots projects like those in the Scott River Valley can really help. Perhaps something like that would work here.

Oh yeah. Now that’s what I like to see. A beaver friend we don’t know yet talking about a beaver friend we already know! The stage is filling up. Soon you won’t be able to swing a dead salmon without hitting someone who knows why beavers matter!

Even in Silicon Valley there are friends looking out for beavers. Take this excellent photo taken by Erica Fleniken of the Southbay Creeks Coalition yesterday morning on the Guadelupe. She says she was watching two beavers swim and snapped this beautiful photo.

Two beavers in January mean kits in June. Big smile.
