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

Month: February 2024


Sometimes scientists seem very very stupid about the most basic human interactions. Like this recent article about about how wildlife celebrity is making studying and managing wildlife difficult. Raise your hand if you can guess what part of “management” gets particularly difficult for them.

Of course we in Martinez know. The killing part,

Managing Wildlife Tricky When They’re Worldwide Celebrities, Like Grizzly 399

Ask that question to many people in distant parts of the country, and even around the world, and their answers might just as likely be Grizzly 399 or Limpy the coyote.

Wildlife has always been one of Wyoming’s biggest draws. But the rise of the social media and instant, global sharing of images and anecdotes from wild critters’ lives have taken the profiles of Wyoming’s celebrity wildlife to a whole new level.

It’s no longer a matter of entire species being gloried, as in “the majestic grizzly.” Now individual animals, such as 399, have a social media presence that many human celebrities might envy.

So, what does that mean for biologists who engage in serious research and wildlife management? In the immediate sense, wildlife scientists don’t think much about it, said biologist Frank van Manen.

Oh I can tell you about it. Having celebrity status makes it hard for all kinds of behind closed doors decisions that get made to manage wildlife, like trapping or thinning the herd or even relocating a trouble some animal.

“From a wildlife research perspective, the well-known status of bears such as 399 — or bear 264 in the Swan Flats area of Yellowstone National Park back in the late 1990s — does not really affect our science,” said van Manen, who is the supervisory research biologist for the U.S. Geological Survey’s Interagency Grizzly Bear Study Team.

Wyoming Game and Fish Department large carnivore specialist Dan Thompson said he worries that the celebrity status of certain animals might distort the public’s views.

“As with human beings, celebrities aren’t always the best role models for how to live one’s life,” he said.

Well duh. Did you think we thought all beavers should act like our famous mom beaver who broke a tooth and died in captivity?

Emotional Reactions

Celebrity animals evoke strong emotions, for sure.

All the way back in 2012, there was widespread outrage when a famous Yellowstone National Park wolf, known as Wolf 06, strayed into a legal wolf hunting zone in Montana and was shot.

Last October, fans far and wide waited anxiously after Grizzly 610 – a grown offspring of 399 – was struck by a vehicle and languished beside the highway in pain. (She later rejoined her cubs and appeared to recover fully.)

More recently, 399’s throngs of admirers joyously hailed her turning 28 last month (the exact date of her birth isn’t known).

And many get a good laugh out of the sly antics of Limpy, a coyote who lives in Yellowstone and how he suckers tourists for pity snacks by exaggerating his leg injury.

Yes people get emotionally attached to wildlife. DUH! In fact even when wildlife isn’t famous people can get emotionally attached to it. You just don’t notice until a gazillion people do it at once.

While all of that might tug at people’s heartstrings, it can detract from a deeper appreciation of bears and wildlife as species playing an important role in ecosystems, Thompson said.

People might project their idealized image of one particular animal onto the entire species, he said.

“I think they (wildlife celebrities) create a false image of the rest of the population, potentially,” Thompson said. “I think it’s amazing that people have had that opportunity to follow that particular bear or other particular bears, and other wildlife species. But that one individual is not necessarily emblematic of all of those bears.

“I’ve actually met some very interesting people over the years that I wouldn’t have without that particular bear (399). But I do think that it takes away from the larger story of that particular bear, or particular bears, when we assign celebrity status to any mammal.”

Moreover, people who know a lot about a particular bear might not understand the larger picture of grizzlies in general, Thompson said.

“Following that particular bear for 28 years doesn’t make you an expert of all bears,” he said.

And the relatively “controlled” setting of Teton National Park (where 399 lives), or Yellowstone might not give celebrity bear watchers a clear picture of grizzly behavior, Thompson said.

Well DUH again. That old woman who brought her grandchildren to see the beavers and told them that their tails start out round and don’t get flat until they grow up was wrong and doesn’t know as much about beavers as Duncan Haley. Big Whoop. People being interested and engaged by wildlife is what starts them getting informed.

It’s a journey.

Even so, the public’s observations can sometimes help bear research, van Manen said.

Grizzly 399 has been on researcher’s radar most of her life.

“Our scientific focus is to understand the dynamics of the overall population, which involves collecting data on a sample of bears across the ecosystem through research captures,” van Manen said.

“Bear 399 is one of those research bears, which is where her number originated when she was initially captured in 2001, representing the 399th bear that was radio-collared by the Interagency Grizzly Bear Study Team as part of the long-term research and monitoring project,” he said.

She hasn’t had a tracking collar on for years now, so it helps to have many eyes on her, van Manen said.

“We have not monitored her via radio telemetry since 2018. Because she resides in an area of the ecosystem where she is very observable, we know a lot about her life history beyond our own monitoring and that has been informative,” he said.

But 399’s celebrity shouldn’t detract from the importance of other grizzlies, he added.

“While there is much focus on these well-known bears, it is important to remember that there are other bears in the population with similar life histories, a few of which we know about and probably more that we don’t know about,” van Manen said.

A New Field Of Study

Social media platforms have created so much attention for grizzlies 399, 610 and other animals, it might have spawned a whole new field of research, van Manen said.

“I’m not aware of specific studies that have addressed the pros and cons of social media attention for grizzly bears in the Greater Yellowstone Ecosystem. However, the influence of social media on wildlife conservation in general is a growing field of academic study, and so far the findings are mixed,” he said.

A 2022 study in Canada found that there was “no tangible benefit” to wildlife through social media fame.

“Interestingly, one of the recommendations (from the study) included how scientists and experts can improve their messages and focus on positive outcomes and solutions, a point well taken,” van Manen said.

I’m sorry. I know you liked it better when it was just you nerds tracking wildlife with your clipboards and a few camera men for nature programs but people care about wild spaces and the things that live in them. I’m sorry if that makes your number crunching harder but they do.

Too bad.


I have two treats for you today, the first is the recorded webinar about beavers and agriculture I so enjoyed last week,

And the second is an article from 18991 North Carolina proving that trappers have always told tall tails about beavers…
Enjoy!

I remember it was Christmas season after the big meeting on November 7 but before Skip had installed the flow device, There was no W0rth A Dam. and not even the thought of one yet. Moses wanted to come  over and show some exciting new footage. I barely knew him back then, but he brought a girlfriend that was someone I did know, one of the superior court clerks for a family law judge I had worked with before. She said she had noticed something about one of the beavers tails.

We weren’t very tech savvy back in those days and it took forever to hook the video up to the TV but when we finally did we saw he had footage of mom and dad beaver mating and that mom had a distinct marking in her tail

It was a very very big discovery. Because it meant we could tell them apart. and that everyone could recognize who was who. (Plus it meant we were having Kits again).

Anyway it was JOYFUL. Understanding tail differences has always been joyful to me. So maybe that explains how happy I was to see this:

AI tells beavers apart by the ‘fingerprint’ patterns on their tails

Computer identification of individuals could help researchers study recovery of the species without stressing the animals

Beavers rely on their leathery tails to steer while swimming and to loudly smack the water as an alarm call. A covering of lizardlike scales makes these tails so handy. It also provides a way to tell the animals apart. According to a study published this week in Ecology and Evolution, a computer algorithm can accurately identify individual beavers by the pattern of scales on their tails, a bit like human fingerprints.

The advance could be good news for the Eurasian beaver (Castor fiber), which was nearly hunted to extinction in the 19th century. As the species recovers, researchers have been estimating the size of populations using ear tags and radio collars. But capturing beavers can stress them, so scientists trained a pattern-learning type of artificial intelligence on images of tails from 100 Eurasian beavers that had been hunted in Norway. The program was 96% accurate at telling the animals apart.

Did you hear that? Finally some good news about AI! Since beavers can tell eachother apart with 100% accuracy and no computer they are still better than us but this could come in handy.

The scientists analyzed photographs taken in a laboratory under good lighting, but the approach should be feasible with images from the wild, they say. In another study, published in the European Journal of Wildlife Research last year, the same team showed that adding a small plastic lens to automatic cameras in the field provided a fourfold boost in high-quality photos—good enough to help computers identify some of nature’s most famously industrious animals.

This is fantastic news because beavers are the wrong shape for radio collars and tail transmitters are famous for ripping our and leaving horrible scars,

Of course you know there are sadistic scientists at CDFW really bummed that they won’t need to put bolts thru beavers to tell them apart. anymore.

Too bad.


I’m so old I can remember when 9 out of 10 beaver articles were about how they were flooding Dan Smith’s property or washing out Mabel

s road. Now the phrase “spoiled for choice” rings in my mind as we consider what treasure to write about next.

Beavers can mitigate drought threat: analyst

MEDICINE HAT — An Alberta conservation group is promoting beaver habitat as a way to keep water on the land amid rising drought concerns in the province.

“Beavers can provide benefits and always have provided benefits from an environmental perspective but also from an ecosystem goods and services perspective with drought and flood mitigation,” said Holly Kinas, Miistakis Institute conservation analyst.

The institute and riparian management organization Cows and Fish are promoting their Working with Beavers website as a tool to assist landowners in introducing beavers and help them understand the technical and regulatory requirements.

Kinas said her organization has been promoting beavers for a decade and Cows and Fish has done it for twice that long. The result is a significant shift in landowners seeing beavers as assets rather than pests, she added.

“We’re finding there is this growing trend and interest in co-existing with beavers instead of undertaking the traditional approach which is, of course, shooting or trapping them,” said Kinas. “A lot of that has been expedited by our changing climate.”

Beavers and their dams mitigate the damaging effects of flooding and maintain a source of water for livestock, said Kinas, and they also help mitigate wildfire impacts.

Isn’t it nice when smart folks are saying the right things about beavers and we don’t even have to correct anything?

Beaver ponds create a huge refuge for wildlife and plant species. Fire can come through, wipe everything else out, burn it to the ground, but there is still this lush, green area surrounding those wetlands created by beavers.”

Resiliency built into the land by beavers is especially key for ranchers who face drought conditions.

“We’ve had ranchers say to us in dry years, they only had one place to water and that was behind the beaver pond,” Kinas said. “Some landowners have said even their well would have run dry if it weren’t for the fact beavers are there and had created this beautiful wetland complex close to their home.”

But beavers can pose problems by flooding fields or roads. The main thrust of the beaver co-existence management tools is to provide technical advice on how to install infrastructure such as pond levellers.

“Maybe you do compromise and give up a bit of your cropland to allow that natural wetland complex but, in return, you are going to have water on your landscape much longer,” said Kinas.

Research has shown that a wetland is like the tip of an iceberg; the surface is a fraction of the total water storage volume, she added.

That’s right. If you give some of your pay check to uncle sam you can give some of your landscape to beavers. I promise it will all be worth it.

eavers are often thought of as woodland creatures, but Kinas said that’s more a result of historical trapping practices that saw a 90 percent reduction in populations. In fact, beavers can thrive on grasslands, though habitat loss has reduced numbers in that ecosystem.

“I have seen an all-cattail dam before, so that does happen sometimes,” said Kinas, though beavers do prefer more wood-based material for building as well as diet.

“They are engineers. They will figure out a way but you do have to have populations nearby or at least enough habitat for them that they could start building dams and have protection from predators.”

Beavers work for a living. Just be glad a lot of that work benefits us.

 


Perfect timing! the San Pedro Valley talk I did last weekend just appeared online. It’s ,mostly ok except for when I listened to it yesterday I realized I mixed up the Russian ships info. Obviously they ca,e down the coast from Siberia, not around the tip of South America! Sheesh!
