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

Category: Beavers and water


Have you ever noticed how people complain about beavers until they want something from them? Yes, we noticed that too. It’s like that annoying roommate you had in college who always talked smack about you and hung out with her other buds until she needed help with her latin paper and ooh then she was your BEST friend ever.

England is doing that with beavers and flooding lately.

Beavers in Gloucestershire’s Forest of Dean ‘settling in well’

A second pair of beavers released in the Forest of Dean as part of a scheme to tackle flood risk are said to be settling in well – and building dams.

The beavers replaced a pair introduced in 2018, the first in Gloucestershire for 400 years, as part of a wider plan to return the animal to the UK’s wild.

But they had to to be trapped and moved after seven months when one was found to have tapeworm, a parasitic disease.

The new pair took their place at the same site near Lydbrook in the autumn.

Beavers were hunted to extinction in the UK in the 16th Century. But efforts have been made to reintroduce them to the wild in areas including Somerset, Yorkshire and Cumbria, while they have also been living wild in areas around the River Tay in Scotland for some years since escaping or being illegally released some years ago.

Oooh sure. You probably GAVE them the tape worm in the first place. But sure get rid of those beavers and start over. How’s it going so far?

Forestry England said their replacements had been captured in Scotland, from different areas of the River Tay. It said the “necessary health checks” had been carried out and the female had been released in the autumn followed by the male a few weeks later.

Rebecca Wilson, from Forestry England, said cameras at the site showed the beavers were “dam building and tree felling” and had “settled in well”.

“Nocturnal dam building is creating deep pools of water, slowing the brook’s flow,” she said. “The tree felling followed by coppicing trees will bring benefits for a variety of wildlife that depends upon more complex habitats.”

Well sure. Now that you have some do-over beavers let them get to work. I’m so old I can remember when a servant or pet got a tape worm you treated him with 9.99 worth of pills instead of killed and replaced. But what do I know?

It is hoped the animals will help prevent flooding in the area by improving biodiversity and building dams and ponds.

The authority said it would be monitoring the “hydrological and ecological changes” the beavers make.

As in, none of the kids really like Martin, and we never, ever play with him. But we invited him to Scott’s birthday party because “It was hoped he would bring his complete set of Pokeman cards” which everyone wants.

Good luck, beavers.


Can speed bumps actually slow traffic?

I mean will the busy flow of uncontrollable cars actually slow itself down based on a tiny obstruction in the roadway repeated over and over again>? Why does no one ever ask that question and why does the other one get poised repeatedly?

Cumbria’s Eden Valley to see reintroduction of beavers

Beavers are to be reintroduced to Cumbria’s Eden Valley to see if they can thrive in upland environments.

The animals, which were hunted to extinction in the UK in the 16th Century, will be introduced to the Lake District for the first time in a trial. Efforts to return the species to other parts of the UK, including Yorkshire and Somerset, are also under way.

The government-approved trial will look at how beavers restore small farmland streams and can aid flood prevention.

Oooh ooh, call on me! I know this one!

It is hoped the beavers will deliver benefits such as carbon storage, flood mitigation and an increase in other wildlife.

Conservationists support the return of beavers to Britain’s rivers for the benefits they can provide in preventing flooding, by damming streams and slowing the flow of water, as well as boosting water quality.

I don’t know. Do you think the repeated  observations of science and gravity will apply in another region? Do you think speed bumps will slow traffic? That’s a real head scratcher. I guess we’ll find out.

The funny thing is that just last night I was reading about the great flood of 1862, and thinking about the timing of this massive event. Obviously all those humans mining for all that gold had some effect. But given the fact that the entire beaver population was wiped out about 20 years earlier and their decaying dams would just about be completely gone  – one has to wonder.

The Great Flood of 1862 was the largest ever recorded in Oregon, Nevada and California’s history. The flooding occurred from December of 1861 until January of 1862, drowning the state in water and leaving much of the Northern Valley unlivable until the summer months of 1862.

The flood created a lake down the center of the state that was 300 miles long and 20 miles wide. It’s estimated that thousands of people were killed in Northern California during the event.

Entire cities were under water and many people were killed. 

The foothills of the Sierra Nevada were seeing tremendous flooding activity during this time. The American River near Auburn rose 35 feet and some of the small mining towns were completely submerged. On the Stanislaus River near Knight’s Ferry, two major bridges washed down the river and anything within 40 miles was completely destroyed.

The year before had extra heavy snow so the melt didn’t help matters. But don’t you think all those missing speed bumps might have had something to do with the calamity?

John Carr wrote about his riverboat trip up the river during the peak of the flood:

“I was a passenger on the old steamer Gem, from Sacramento to Red Bluff. The only way the pilot could tell where the channel of the river was, was by the cottonwood trees on each side of the river. The boat had to stop several times and take men out of the tops of trees and off the roofs of houses. In our trip up the river we met property of every description floating down—dead horses and cattle, sheep, hogs, houses, haystacks, household furniture, and everything imaginable was on its way for the ocean. Arriving at Red Bluff, there was water everywhere as far as the eye could reach, and what few bridges there had been in the country were all swept away.”

 It’s a terrifying story of our history that I knew nothing about before. When Stanford was inaugurated governor of California he had to row his way to the capital.

I bet a lot of those beaver hats got floated away too, Ironic, huh?


Anyone who’s ever made an offer to a two year old knows this rule.

You want them to FEEL like they have a choice and get to call all the shots. But because you happen to be the adult and know better you want to actually put your thumb on the scale and determine which option they are going to pick. It’s called stacking the deck, Like “Would you like to wear a sweater or your snow gear to play at Martin’s house?”

They win. You winner. It’s a perfect system.

Which bring us to Lyme Connecticut, the state still trying to solve its beaver problem.

82-Year-Old Old Lyme Resident Faces Loss of Home as Local Officials Consider Response to Flooding

OLD LYME — For more than a year David Berggren’s house has been sinking, and Black Hall Pond has been steadily rising due to beaver activity downstream, flooding his lawn, and dock, causing his plumbing to fail and mold to grow, and shifting the foundation underneath his home on Boughton Road.

“I trapped three beavers on town property near Whippoorwill Road,” said Robert Comtois, the trapper hired by the town, “but they may not have been the suspects. I did try to get back into the opposite bank of Black Hall Pond, but it was so thickly grown-in, I was having a tough time even with my kayak.”

So there can be a drowning 82 year old man or there can be beavers. Which one do you think we should save? We first read about this problem back in June. So you can see they’re tacking this issue with lightening speed. It’s funny because you’d think that was if your property was under a little bit of water in the summer it would be under a LOT of water by January.

I remember it because of the disease. That must be fun to explain to tourists.

Despite the efforts of Machnik, town officials, members of the Open Space Commission and the Old Lyme Land Trust have for months denied knowing either location of the beaver activity responsible for flooding the property of Berggren and his neighbors, or ownership of the land.

“All we know is it’s not on our property,” said Amanda Blair at a December 13 meeting of Old Lyme’s Open Space Commission. “To the best of our knowledge, there is no beaver dam located on the Jericho Preserve,” said Michael Kiernan, president of the Old Lyme Land Trust, in a December phone call with CT Examiner. “We worked with the DEEP expert in 2017 to determine this. At that time, it was determined that the dam was located on one of the private properties to the north of the preserve.”

Two years later, Berggren, Machnik, Comtois and several Black Hall Pond area residents maintain that the dam is clearly located downstream on Bucky Brook, deep in the Jericho Preserve.

Kiernan said an investigation is ongoing.

So they don’t KNOW where the dam is that’s causing the problem but they just keep randomly killing every beaver they see because they hope it will help. That’s like not knowing who robbed the bank but just jailing every person you meet on that street until the atm’s fill up again.

Gosh. Connecticut really is – um – challenged when it comes to beavers.

On December 16, newly-elected First Selectman Tim Griswold said the town would look into using a drone to locate the beaver dam and to determine the responsibility for the flooding.

Two weeks into January, there has been no apparent progress toward resolving the issue.

In multiple conversations with town officials, it has been assumed that only the property owner may authorize the trapping or managing of beavers — in this instance, it appears, the Old Lyme Land Trust. According to both Machnik, and the Department of Energy and Environmental Protection, as a matter of law that is not the case.

You know what state Connecticut borders? Massachusetts. The town of Lyme is about  75 miles away from Mike Callahan at beaver solutions. He could tell which – if any – beaver dams is causing the property to flood, And fix it for you without killing beavers or complaining to the press for 6 months.

But that would be too easy, right? Better to keep killing beavers and sinking lower into the mire.

 


Isn’t that beautiful? A friend found it for me and my heart was very touched. Things in Australia are beyond horrific, I wish an import of beavers could help. Sigh.


Time for another installation of “Lets use physics to study what beavers could do naturally if we just stopped killing them all the time.” From our friends at Phys.org.

Toward a smarter way of recharging the aquifer

To replenish groundwater, many municipalities inject reclaimed water into depleted aquifers. The injected water has been purified by secondary wastewater treatment, and, in some cases, the water has been treated through tertiary processes and can be clean enough to drink directly.

The original water in the aquifer was chemically stable, in equilibrium with the surrounding rocks, and was slowly recharged by natural processes (water infiltration). However, when more groundwater is consumed than the natural processes can restore, engineered recharging with purified, is needed. Unfortunately, over time, the reclaimed water sometimes becomes contaminated.

Well gosh! Landowners are using so much water that they drain of the water table and have to inject it back. Like refilling your bank account, fair enough. But it’s so weird! When they put clean water in it comes out tainted with arsenic! What’s with that?

When we injected the water, it was good,” she said, “but when we withdrew it, it was bad, tainted with arsenic. What was wrong?”

It turned out that although the water being injected into the aquifer was usually clean enough to drink, it was bringing something new to the aquifer: oxygen.

“By injecting reclaimed water, we are triggering oxidative dissolution of sulfide minerals in the aquifer, which were stable at low oxygen levels,” she said. In particular, she looked at arsenopyrite (FeAsS), a mineral that dissolves into iron, sulfur and, crucially, arsenic.

Wait, that’s poison right? I mean if you drink arsenic you die don’t you? At least that’s what happened with those nice little old ladies serving tea to Cary Grant. What rotten luck! You need water so you use water. You will need water in the future so you replace it to save for a not-so-rainy day. And then when you take it out again it gets full of poison! That’s horrible! If only there were some some way to stop it from going all lethal.

Dissolved organic matter keeps water from turning into aresenic? You mean like sticks and leaves and bugs and fish and things that have been broken up in the water over time? Gosh if there were ONLY some tool that could get water back on the land. Recharge the aquifer naturally AND generate lots of DOM so that people won’t be drinking arsenic.

Come on. Snap out of it! Stop you crazy dreaming. What are the odds of all that ever happening naturally?

 

 

 

 


Fires and floods are the punishing destructive forces of nature that even the bible recognizes. The answer to both might be staring us in the face. What if what we needed all along wasn’t an ark, but a some beavers? 

The National Trust is preparing to release a small number of beavers into the south of England to help manage the landscape and combat flooding.

In a scheme to combat flooding, the National Trust is planning to release a small number of beavers in England. Initially, two pairs of beavers will be released into large woodland enclosures in Holnicote, Somerset, near tributaries to the River Aller. A third pair of beavers will be released into an enclosure at Valewood, on the edge of the South Downs, West Sussex.

Beavers, once native to Britain, were hunted to extinction in the 1500s, although small numbers have been observed in the wild in Scotland and Devon in recent years. Beavers are considered a ‘keystone’ species due to their work building dams in rivers, which significantly affects the landscape and ecosystem around them. Through dam building, beavers help restore precious wetlands through erosion reduction, downstream flood control and water cleansing. However, scientists have also raised concerns about the volumes of carbon being released into the atmosphere from soil as a result of beaver damming.

That’s right. Beavers to the rescue. Again. Although no solution is without its risks. Noah might deserve full disclosure.

“Beavers are nature’s engineers and can create remarkable wetland habitats that benefit a host of species, including water voles, wildfowl, craneflies, water beetles and dragonflies,” said David Elliot, National Trust lead ranger for Valewood. “These in turn help support breeding fish and insect-eating birds such as spotted flycatchers.”

Well said.

Yes they do. And if prevent flooding’s not enough, maybe you’ll be interested to know they can also reduce the risk of fire.

Don’t believe me? Ask a scientist.

Smokey the Beaver: Can Beaver Dams Help Protect Riparian Vegetation During Wildfire?

When beavers move onto a creek, they build dams that slow the flow of water and spread it out over the landscape. That stored water can help keep the entire landscape wet and lush, even when everywhere else is dry. People have seen beaver-dammed areas stay green through droughts before, and this past year photographs of green beaver wetlands surrounded by the char of wildfire showed up in the news media. Although we are seeing this happen, there weren’t any studies proving that places with beaver damming are burned less by wildfires than places without beaver damming. We looked at five different large wildfires that burned in places with beavers, and use satellite data of plant greenness to see whether or not the plants actually stayed green and healthy during the fires if they were near beaver dams. Our data confirms what people had already seen happening: places with beaver stay green even during wildfires, places without beavers do not. For a short (45-second) animation of this phenomenon,

Wow! December 11 in San Francisco.  That would be our own heroine Emily Fairfax who wowed the world with her smart research and stop motion film last year. Emily started work as an assistant professor at Cal State Channel Islands and if she keeps this up I’m expecting great things for her and beavers.

Some say the world will end in fire,
Some say in ice.
From what I’ve tasted of desire
I hold with those who favor fire.
But if it had to perish twice,
I think I know enough of hate
To say that for destruction ice
Is also great
And would suffice.
