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

Month: December 2023


My great-great grand father John Perryman was a tin miner in St Austell Corwall England. When he was 49 he was lucky enough to be working with three of his grown sons in the Wheal Eliza mine. Now since John was an old man by miner standards he had the least qualified job of “trammer” who drove all the debris and rock the miners produced out of the shafts using a wagon. It was grueling work loading and unloading heavy cargo and I’m sure the more trips of this kind you made the better your dingy pay was.

in November of 1869 he made the trip for the last time. The wooden frame holding the path gave way and he was crushed under the wagon, Dying in the mine was not unexpected but was still a somber thing. Big enough deal  that an “inquiry” was conduced.

From Royal Cornwall Gazette 13th November 1869
Coroner’s Inquest John Perryman

“He wasimmediately carried home and a surgeon sent for, who on attending him gave no hopes of his recovery, on account of the severity of his injuries. The captain of the mine gave evidence to the effect that the wooden viaduct was not fit for use and was not in use, that deceased had no right or business there, therefore to a certain extent the accident was his own fault. A verdict of “Accidental death” was returned.”

Which means the inquiry was really more of a pagent, which I guess they often are when powerful bodies investigate themselves, I’m sure there was no one in St Austell that was surprised by the outcome.

Some times the deck is stacked, whether you are a miner or a beaver.

Officials find no wrongdoing in Park City beaver habitat removal

The Utah Division of Wildlife Resources investigated the removal of the beavers, and the Division of Water Rights investigated the removal of the dams. Both investigations found no wrongdoing.

However, the dam removed at McLeod Creek was not developed enough to be protected.

“In this case, there was no evidence of any heavy equipment in the channel itself,” Rasmussen said. “It looked like they did minimal damage in the removal of it. And therefore, it was determined that really no permit could be required for that.”

So you see, the dam was too little to matter, and the beavers too dead to protect. These things have a way of solving themselves, don’t you think? I believe Upton Sinclair said it best:

It is difficult to get a man to understand something when his salary depends upon his not understanding it.


My post on Friday about beavers being in “every river, brook and rill” prompted a lot of discussion and a genuinely knowledgeable comment from Evan the ecohydrologist who asked where it came from and

“I ask because that exact phase “every river, brook, and rill” was written by Harry Radford in 1907 in reference to the landscape of northern New York State. He presents these as his observations and assumptions, there’s no reason to believe he’s quoting Champlain. See “Eager” by Goldfarb, page 43-44 for a reprint of the Radford quote, or also the original Harry Radford 1907 “History of the Adirondack beaver” quote on page 396 of this citation:

Radford, Harry V. 1907. “History of the Adirondack Beaver: Its Former Abundance, Practical Extermination, and Reintroduction.” Annual Reports of the State of New York Forest, Fish, and Game Commissioner for 1904, 1905, 1906, pp 388–419. https://catalog.hathitrust.org/Record/100349977.

And my initial lightening storm of thoughts went something like this:as “Dam, that guy knows his stuff”  and “Oh boy am I stupid I don’t even know who I’m quoting” and then defensively “Jeeze I’m doing my best here and it’s not like I get paid for this or the website costs you anything” and then seamlessly “WOW the website has a long time reader! Someone actually reads this that isn’t related to me!”

Okay, then i put all those thoughts on a shelf to think about  later and I went searching through the site to find where I thought the quote came from and I saw articles where I quoted it in 2015 and before that in 2012 and before that in 2010 and before that in 2009! Which I’m sure you’ll agree is  very long time ago. November 2009 was the first time it appeared on this website in a post called “Where have all the beavers gone?” which preceeded even our historic papers.

Obviously that was before Ben’s book and before Frances book and before Leila’s book and before I had read much of anything about beavers at all except for Dietland Muller Swarze book which I had browsed on a plane on the way back from a APA conference on assessing family violence in divorce in my old life as a shrink. A LONNNNG time ago.

So I wandered through the november posts for that year to figure out what I had read that prompted me to write that and I found  one aptly called Revelations” where I was just starting to read Lily Pond by Hope Ryden and was struck by the historical writing she did where she found out that beavers used to enjoy life in the sunshine before the trapping obsession forced them to become nocturnal. Then I looked up her book and found this: on page 46 of Lily Pond to be precise:

So there it is. Hope was writing about what Samuel De Champlain saw and she used the evocative writing of Henry  Radford in the early 1900s who specfically said beavers inhabited every “River Brook and Rill” and  was probably translating Samuels words when he said that in 1622 the adirondacks were “peopled” with beaver.

So it was my mistake to combine the two but a fairly understandable one and I could tell exactly why I made it, Hope got interested in the idea because she noticed that beavers didn’t have eyeshine like other nocturnal animals. And when she read up on it she realized that they used to be out in the day and became nocturnal when they were ruthlessly trapped. In fact by 1895 many states reported they no longer had beavers.

One can speculate that the few animals that escaped this continent-wide decimation must have been the wariest of their kind, deviants, disinclined to build conspicuous lodges. And inded, the late ninteeth-century reports of sightings describe the beaver as a reclusive bank-dweller. One can also speculate that these survivors escaped the notice of trappers by turning night into day, for by the end of the last century, no further mention is made of beavers “sunning themselves on their lodges”.

Hope Ryden: The Lily Pond pg 48

Even though when Samuel De Champlain toured the adirondacks in 1623 there were beaver in every “River, Brook and Rill” according to Harry Radford who described the decimation of beavers three hundred years later.

I’m so happy to finally get it sorted, Thank you Hope, Harry and Evan!


The stupidest headline I’ve ever read on phys.org.

Are wetlands really a flood risk? Experts debunk most common myths around these precious ecosystems

See wetlands must cause flooding because places with big wetlands like the bayou and the everglade are always flooded. AmIrite?

Why do myths and legends surround wetlands?

From mangroves and seagrass beds to peatlands, reedbeds and grasslands, wetlands are not only inundated with water, but also mystery.

Bog bodies—naturally mummified human cadavers—have been getting dragged out of peatlands for decades, spreading fear among Europeans.

Dr. Alexandra Barthelmes is a senior researcher at the University of Greifswald and Greifswald Mire Center in Germany. She works alongside more than 50 passionate scientists, many of whom are also involved in WET HORIZONS. Her team provides geographic information on Europe’s peatlands for the project.

“Many people believe it is dangerous to go to peatlands as they are worried that they will get there and just sink—but this is not true. You may sink in up to your knees, but you would have to work very hard to bury yourself.”

“Of the bog bodies found, many have had injuries and it seems others were sacrificed in some way,” she adds. “All the evidence indicates that most of the people were taken there on purpose as they simply didn’t ‘belong’—so peatlands being these places of danger really is an age-old myth.”

Really? Watch out for wetlands because you might sink in them?

The danger of sinking to your death is just one of myriad myths that European wetland experts are now racing to dispel as they strive to restore these ecosystems.

“We’ve been able to spread shredded pieces of peat moss in formerly drained peatlands, with a lot of success,” she says. “And if Sphagnum is successfully reintroduced and the water table kept stable, we find that many other specific bog species return.”

Once established, the Sphagnum stores carbon, reducing carbon dioxide emissions, and also helps to prevent the release of pollutants into ground and surface water.

Meanwhile habitats for threatened species can be created. And if harvested the moss serves as a perfect substitute for the peat-based substrates still used by large- and small-scale farmers to grow vegetables.

This critical source of agricultural revenue also dispels a third common myth: that wetlands are doomed to become economic wastelands.

n each case farmers can earn money from the sale of the biomass, the saved CO2 emissions and also from agricultural subsidies they may receive. For many paludiculture projects, the production chains are ready, making large-scale implementation the next critical step.

Huh this is a shock! Wetlands aren’t useless and you won’t sink in them. Apparently some English people are very very stupid. (Now don’t be alarmed. I am married to one and can say for a fact that is without a doubt true…)

Are wetlands a flood risk?

Revenues aside, many perceive wetlands to be a , whereas the opposite is actually true.

Whaaaatt?

Nature’s wetlands store flood water during storms, acting like natural sponges that soak up surface run-off and slowly release it later.

But once wetlands are drained to create farming land, with grassland replaced by crops such as wheat and maize, flooding risk rises. Factor in how fields are left bare over winter—drastically increasing surface water run-off—and drained regions can pose a real problem.

“Wetlands are only a flood-risk after they have been drained for [agricultural] use,” says Barthelmes.

Well good luck to you, Barthelmes. you have your work cut out for you myth busting among the beavers-eat-fish crowd. Maybe this sagely  illustrative graphic will help. Let me know if you think it’s too advanced for folks up there to understand:


The french cartographer and founder of Quebec, Samuel de Champlain, once wrote that beavers in the new world in 1600 occupied “Every River. Brook and Rill.”

I was thinking in particular about this sentence about the word “Rill” which isn’t used much today in conversation today but does still have a specific geomorphological meaning. Wikipedia defines a rill as a shallow channel (no more than a few inches deep) cut into soil by the erosive action of flowing surface water. “

It occurs to me that when you’re a child making an ambitious sand castle at the beach and you and your cousin scoop a long trench from the waves to your creation in the hopes of bringing water to your moat that this is a kind of manmade “rill”.

And more importantly when beavers dig canals out from a pond to extend their territory to reach more trees and have an easy way to haul them back that is also a RILL. In fact a rill might be described as a path where water will go when the right conditions arise. What we today would refer to as an “Ephemeral stream“.

I am thinking that Ephemeral just means “without beavers“.


Residents of Calgary has joined the number of cities that would very much like to stop killing beavers please. City officials just aren’t so sure the can quit.

Calgary urged to adopt better co-existence program with beavers after animals killed

Over the summer, a pair of beavers were an attraction for people walking by a storm water pond just north of Country Hills Boulevard. However, in October, the City of Calgary hired a contractor to set traps that killed two beavers.

“When we found out they killed two beavers that we had been watching all summer, it was a lot for everybody to take in,” said Andrew Yule, president of the Nose Creek Preservation Society.

The city says the beavers had to be removed because they created a dam that was blocking an outlet that controls water levels in a storm water pond east of the community of Coventry Hills by Coving Road N. E. It resulted in high water levels in the pond, posing an increased risk of flooding in the area.

You know how it is. Beavers build dams and that just naturally leads to killing. It’s nothing personal you know.

“It was really neat to watch how beavers help wetlands but at the same time you don’t want that in your infrastructure … Understandably, something had to be done.”

He’s concerned that since the beavers were destroyed, it may make people reluctant to report them to the city or to citizen science apps, which help with conservation work.

“Having the concern that if you report a beaver, it’s going to get killed is counterintuitive to what we want people to do,” Yule said.

What do they know anyway! People want to save everything if you put a hastag by it.  These things have to be done by grownups.

The city says relocating beavers to other areas is not an option.

Alberta Environment and Protected Areas does not support moving beavers because there is a low rate of beaver survival and an increased risk of the transfer of diseases. Relocation can also upset the balance of ecological functions and can potentially create future human-beaver conflicts, a City of Calgary spokesperson explained.

Lets hope they get a few hundred residents like the one in the video a solid dozen of them know how to use the internet to look up tools for coexistence.

Because you know if they have to wait for city officials to figure it out there may not be any wetlands left.
