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

Category: Who’s blaming beavers now?


I’m always fascinated when Florida writes about beaver. Of course you know the primary mystery associated with their existence, right?

Copy (3) of DSCF0200Mike Adams: Rodents must gnaw to survive

Rodents are the largest family of mammals on the planet.

The name rodent, from Latin roots, means “gnawing animal” because of the rodents’ large front incisor teeth and the way they eat. Their incisors are used like chisels to gnaw and nibble on hard foods like nuts and wood. These incisors must grow continuously since they are worn down by gnawing, sometimes on bone or deer antler. Because they do not stop growing, the animal must gnaw to wear them down; otherwise, the teeth continue to grow and will eventually kill the animal.

Rodents have adapted to almost every terrestrial and freshwater wetland habitat, from cold tundra, where they can hibernate under snow, to hot deserts, where they seek shade during the extreme daytime temperatures.

Of course, this family comprises many species and habitats in our state. This includes muskrat, squirrels, pocket gopher, mice and rats.

The largest is the semiaquatic beaver, about 3 to 4 feet long weighing up to about 50 pounds, which lives more in the Panhandle region, although some have been documented around Gainesville. The smallest rodent is the white-footed mouse, about 2 to 4 inches long, weighing about an ounce, which can be found in many upland/wetland transitional and coastal habitats. The nutria, an introduced species from South America, is smaller than the beaver. This luxuriously furred muskrat-like creature that can be seen along the banks of the St. Johns River and tributaries.

Our largest rodent — the beaver — is considered an ecosystem engineer with its dams and lodges built of gnawed tree trunks and branches forming backwater reservoirs. These areas provide valuable habitat to other wetland-dependent species including aquatic birds and fish. Some rodents may play a role in maintaining healthy forests.

I think this article was updated to contain info on the nutria – whose photo adorns it. I’m sure someone originally posted it thinking it was a beaver and then got a letter and went oooohhhh. Not even from me this time, I promise. Nice that he mentions how beavers make habitat for other species and are considered ecosystem engineers. But no clue how the heroes exist alongside that toothy neighbor.

But they do somehow. Don’t ask me how.

3924000315_820a75befd[1]Even if there is a reason for their constant chewing, folks still get upset with their target choice. I’ve been seeing this complaining article all over the internets the past few days. I guess Mr. beaver chewed the wrong tree.

Hungry beaver to blame for temporary power outage in Slippery Rock area

About 10,000 West Penn Power customers in the Slippery Rock area were without power for less than a minute Thursday night while crews made emergency repairs to a transmission structure, a utility spokesman said.

A beaver chewed through a large tree, which company officials feared might topple onto a transmission line and cause a longer outage, West Penn Power spokesman Todd Meyers said.

Slippery Rock University was impacted by the temporary outage.

There must be a standard memo power companies circulate in times like these. Maybe my dad even saw it.

Leave it to beavers: Live cameras offer glimpse into nature

The beaver dam live feed has gotten 10,625 views this year with people viewing from as far away as Poland, Saudi Arabia and Kazakhstan. The average viewer watches the feed for nearly 10 minutes.

The U.S. Forest Service has run the camera from the Mendenhall Glacier Visitors Center since 1995 and began live-streaming in 2009, according to Natural Resource Specialist Peter Schneider, who runs the feed.

Because of bandwidth limitations, the Forest Service can only stream one camera at a time; they switched their feed from the beaver den to an in-river sockeye feed Thursday.

That’s right, it doesn’t matter if folks were watching from Kazakhstan, because SALMON! SALMON! SALMON! Those beavers will just have to get out of the way and let the real stars have stage time.

And speaking of a Forest Service who’s willing to push beaver aside to save the ‘widdle fishy’, check out this story from Colorado.

Forest Service seeks public’s input on Fryingpan trout restoration plan

The U.S. Forest Service is eyeing an ambitious seven-year plan to restore native cutthroat trout to the upper Fryingpan River watershed and eradicate whirling disease, and the agency wants public input on the endeavor. In a lengthy statement released Friday details the Aspen-Sopris Ranger District’s plan, which includes constructing stream barriers and a 20-acre reservoir; the use of a “fish toxicant”; construction of a quarter-mile, temporary road; and possibly using explosives to remove beaver dams.

“Native cutthroat trout are no longer found in most of their historical range due to non-native fish invasion, habitat loss and disease,” the release says. “Recent research has revealed several lineages that were formally unknown in Colorado, including a lineage of Colorado River cutthroat trout native to the Roaring Fork watershed.”

The portion of the plan “to assure a complete eradication of non-native trout and whirling disease” would involve the administration of the chemical Rotenone by Colorado Parks and Wildlife. Rotenone is an organic plant-derived pesticide and is the most commonly used fish toxicant in the nation, the statement says.

“Once complete elimination of trout from the entire watershed above the barriers is confirmed through sampling, the stream would need to remain fishless until it is confirmed that [whirling disease] has been eliminated from the system,” it says.

The second phase would include trapping beaver families or colonies and relocating them in Little Lime Creek “to the extent practical.”

Because you know how bad beaver dams are for trout. And how good pesticides are for them. I mean why shouldn’t the federal government spend our tax dollars poisoning fish and terrorizing beavers on the off chance that it will let them eliminate ‘whirling disease’ which was probably triggered as a response to some pesticide anyway? Makes perfect sense to me.

Sheesh!
We’ll be planting trees this evening with some children and Suzi Eszterhas as part of a photo needed for the Ranger Rick article. (Of course it’s the worst possible time of year to plant trees, but Jon will probably rescue them afterwards and save them in the garden until winter rolls around again.)

Our friend at the Jeff Arnhorn nursery of Livermore chose some wonderful specimens and even delivered them himself. When he dropped them off he saw Mario’s Mural and was very curious because Mario happens to be doing construction work for his mother! (Mario told us earlier that painting doesn’t pay the bills and has to do construction as well.)

Is there a smaller world than the beaver world? I do not think so.

Mary had a little lamb,
Its fleece was white as snow;
And everywhere that Mary went
The lamb was sure to go.

Mary had a little lamb. It was probably the first song you played on the plastic recorder in third grade. Did you know the original poem was written by the author and editor Sarah Jopsepha Hale about the real child Mary Sawyer who lived in Stirling Massachusetts?  Supposedly the little girl really did bring her lamb to school one day and it really did make the children laugh and play (which of course children would never do normally). Later Sarah also published one of the first novels against slavery, and was famous for writing that while slavery dehumanizes the enslaved, it also dehumanizes their masters and retards national progress. Good point!

Flash forward 180 years and apparently they can tolerate lambs in educational facilities in Stirling, just not beavers in creeks.

Selectmen say beavers must go

 “The intent was to sell the property once we put the easements in place,” said Town Administrator Michael Szlosek. “But the center easement was too intrusive. The desire was to get the Conservation Commission to move that center easement.”

But even with a less intrusive easement, there is still the matter of the beavers.

The selectmen agreed that, although there has not yet been any committed interest from a prospective buyer, the flooding caused by the beaver dam decreases the value of the property and that the dam must be broken and the land dried up before the parcel can be sold.

“You can’t trap and relocate beavers because they are a nuisance animal,” said Szlosek. “There is no place to put them. Nobody wants to kill the animals [but] the beaver population in Massachusetts has exploded over the last 10 or 15 years. What else can you do? They’ll continue to breed and they’ll flood more land.”

Because of the restrictions on lethal trapping, the animal control department is not able to preside over this matter. The town of Sterling will need to seek out a private company that can provide the trapping service.

“There was a referendum banning almost all trapping in Massachusetts so you really have to go through a lot of hoops to be able to do it,” said Szlosek. “Obviously, we will have to observe that.”

According to Szlosek, the season during which permits can be granted to trap beavers is between Nov. 1 and April 15. During the off season, appeals can be made to the Board of Health and a permit can be issued if the presence of the beaver dam demonstrates an impingement on personal or environmental safety.

“They’re relatively harmless creatures except that they can cause a lot of damage to properties,” said Szlosek. “They’re indirectly destructive to other species because they destroy their habitats.”

Destructive to other species because they destroy their habitats. Just pause a moment and let that sink to its full outrageous effect. Beavers destroy habitat. I obviously have been lying to you all these years and misleading the children at the beaver festival. We really should be doing an Demolition Beaver bracelet activity and teaching how they ruin things for fish and wildlife.

Mr. Szlosek gets a letter. And maybe a poem.

Stirling had a beaver dam
The babbling brook was stilled
Szoslek wants the dam removed
And all the beavers killed

The fish will have to go away
the muskrat, otter, mink
And all the birds that hunted there
go missing with the link.

 

 


Global beaver citizens that we are, I woke up with an email from the Edinbugh professor and regular reader of this website J. Suilin Lavelle, who said she just ran into Roisin Campbell at the mammal conference on the weekend! Roisin told her she had a lot of fun on her visit to Vermont meeting Patti and Skip. (Which I wrote about a few days ago because, honestly that’s how small the beaver world is.) The beaver champions of that nation are currently in a Brexit-induced panic because the Scottish government had dragged their beaver decision out for so long, and now the insanity over the EU vote might delay or derail everything.

You probably didn’t realize that Brexit was bad news for beavers too, did you?

Meanwhile, there’s a nice bit of news from the Mendenhall Glacier beaver cam this year, which I was recently alerted to by a US Forestry friend here in Vallejo.

Thousands Around the World Tune In to Snoop on a Beaver Den

Watching the beavers sleep has kept thousands of viewers occupied since June 28, when the US Forest Service installed an infrared camera in the den to record in real time the beavers’ activities. As nocturnal creatures, that means sleeping most of the day and getting up periodically to stretch, eat, or relieve themselves. Recommended viewing is between 7 AM and 7 PM Alaska Standard Time.

Natural resource specialist Peter Schneider and fisheries biologist Don Martin initially set up a beaver camera in 2004 to satiate their curiosities about a collection of food outside the beaver lodge on Steep Creek. To monitor the beavers’ activities, they set up a camera outside the lodge and even had it insulated throughout the winter.

Are you keeping track of the mileage with your atlas at home here? The beaver story has gone from Scotland to Vermont to Juneau to Vallejo to Martinez so far. Some 2500+miles and counting. Not bad for a morning’s work!

And just so we don’t feel too smugly accomplished, here’s a glimpse of how far we have yet  to go courtesy of the silliest research ever published.

Yes. that photo is what you suspect it is; because you, dear reader are smart and this article is stoo-pid.

As more beaver colonies form, the rodents have an adverse effect on the climate by changing levels of methane gas. This happens because beaver colonies are formed in ponds constructed by the beaver dams. These tend to be pockets of shallow water (no more than 1.5 meters high.) Within this oxygen-poor standing water, methane gas levels build up and the gas, because it cannot dissolve in the water, is eventually released into the atmosphere.

According to Professor Colin J. Whitfield (University of Saskatchewan in Canada), compared with 100 years ago, 200 times more of greenhouse gas is released into the atmosphere from beaver colonies. This has come from a study into beaver colonies in Eurasia (the Castor fiber species) and North America (the Castor Canadensis species.)

The model suggests beavers currently contribute 0.80 teragrams (or 800 million kilograms) of methane into the atmosphere. Interviewed by International Business Times, Professor Whitfield suggest this problem not going away anytime soon unless action is taken: “Continued range expansion, coupled with changes in population and pond densities, may dramatically increase the amount of water impounded by the beaver…[this] suggests that the contribution of beaver activity to global methane emissions may continue to grow.

Truly the reporter selected the IDEAL photo to accompany this groundbreaking research, it really communicates the level of intelligence of those involved. (Nutria) See Dr. Whitfield is from the university of Saskatchewan which is famous for the kill contest they held this year.  He teamed up with Dr. Cherie Westbrook of Alberta who was probably just happy to publish something without the name Glynnis Hood on it, and I’ve been told that she regrets how this study has been misused. But I spare her no mercy and want this supposedly seminal research to be the beaver albatross around her educated neck. She should have known that folks would be only too happy for another bogus reason to blame beavers.

Let me explain this again for those who are mislead, yes beaver dams release methane, which is one of the green house gasses we are not really worried about. It dissolves in 2-3 years, unlike carbon, which we are VERY worried about, which lasts for decades.  (When you drive to work your car doesn’t release methane.) Along the way beavers increase the water supply which we are going to need as carbon numbers keep rising. Beavers also aid biodiversity, which we need in on a planet that is rapidly losing species. (I of course tried to write the editor yesterday about the photo, but it appears they are obviously not overly concerned with accuracy.)

Oh and did you know that we successfully entered Jupiter’s orbit  after the fireworks on independence day? We’re on a 20 month rotation studying a planet at 540,000,000 miles away. And the five year mission predictions were accurate to within 1 second.


Welcome to Jupiter!


We are just two weeks from the purifying ritual that occurs every year apparently at SARSAS in Auburn. Before they invite me to come tell the truth about beavers, they conjure the opposite so as to soothe the evil bureaucratic spirits. I guess them helps sneak me in the gates, so to speak, since the powers that be are thus duly convinced they hate beavers.  By the time my booming beaver beatitudes arrive no one of consequence suspects anything.

By evil spirits, I’m referring, of course, to Mary Tappel, who still takes time out of her busy life on the water board to spread vile lies about beavers. I once  called her the ‘human beaver deceiver‘. Her bio in the SARSAS newsletter has some rich allegations of her merry volunteer brigade and their wondrous application  of various nonlethal techniques. But this is my favorite one.

 Mary also dealt with beaver management questions and in foothill areas such as Granite Bay, Loomis, & Roseville; and towards the Bay/Delta area in Fairfield & Martinez, and to the south in Elk Grove, all in creeks and small retention basins.

surprised-child-skippy-jonSo not only does Mary have the outright gall to take credit for the unrivaled beaver slaughter in Elk Grove and Granite Bay (The biggest beaver genocide in 2007 and the site of the most depredation permits in 2013-14.) She also PROUDLY proclaims her work in MARTINEZ.

We’re actually on her resume.

What was her service to the home town of John Muir you ask? Fortunately nothing at all that was useful or true. She told the Gazette that beavers breed for 50 years. She told our mayor that flow devices never work. She advised city staff to kill the father beaver so that the mother would be forced to mate with her offspring. And, at a public meeting of 200 people nearly a decade ago said that the beavers were leaving Martinez, and wouldn’t be a problem anymore.

I have to say I remain very grateful for her unique level of competence.

Maybe I’ll thank her publicly when I come present in June and talk about the many transformations that beavers made to our creek in Martinez. I’m constantly reminded of how many individuals’ incompetence was instrumental in saving our beavers. The lawyer on the subcommittee who wanted them trapped, for instance,  was lackadaisical at best in his half-hearted efforts to convince the city they would ruin the creek. He brought a large stuffed beaver once to the meeting with a sign that said ‘send me to Plumas county’. I thought maybe he was just ineffective generally until I saw him speak on another issue in opposition at a meeting. In that instance, he was forceful, competent and had done all his homework, which is what my lawyer friends told me he was like in court.

If THAT attorney had shown his face on the subcommittee we might have had a very different outcome.

As it was, folks just didn’t really care that much. Maybe enough to toss some money to hire a lawyer, but not enough to do research and really examine the allegations in the case. Like say, um, me for instance. If I had been my opposition, there would have been trouble.

Thanks, Mary.
