It’s not clear yet whether this is one beaver who escaped from elsewhere or a pair who were released by rewilders, but it sounds like a good dam move to me!
A couple whose garden was being vandalised in the night has uncovered a surprising culprit in Wales’ first wild beaver for 400 years.
The dam-building rodent was discovered by a husband and wife who noticed trees going missing and machete-like damage in a field next to their house in Pembrokeshire, west Wales.
Curious about the cause of the damage, the homeowners bought a ‘stealth camera’ which captured footage of the creature swimming in their pond and felling their trees.
The origins of the beaver are unexplained, but the landowners believe it may have come from an unsanctioned release by rewilding enthusiasts.
The rodent has been found living near a rural property where it has started to build itself a lodge under the family’s pond deck.
Nicknamed Anthony by the family – after military historian Antony Beevor – the herbivore has become as ‘fat as a pig’ spending as much as six hours a night chewing tree trunks and dragging branches around.
The discovery is only the fourth time a beaver has been found living wild in Britain.
Beavers – which can grow to be the size of a large spaniel – were hunted to extinction in Britain 400 years ago, but have been slowly reintroduced in recent years.
The landowners, who wished to remain anonymous to protect the location of the animal, were ‘astonished’ to discover the herbivore was living behind their house.
They said: ‘Some of our trees began to go missing overnight and others were simply being mauled. It looked like someone was hitting them with a machete.
‘There are no deer in Pembrokeshire, so we couldn’t work out what was causing the damage.
‘The only clue were some teeth marks left in the bark.’
Two weeks after first noticing the damage, the couple decided to buy a £100 stealth camera and leave it out overnight to try and catch the vandal in action.
When they reviewed the footage a week later, they spotted the creature.
‘To our astonishment, the camera showed a beaver swimming around our pond and eating our trees. We couldn’t believe it.
‘Since then, it has cleared quite a few trees and branches.
‘There is nothing subtle about a beaver. They are very easy to spot.’
The closest official colony of beavers to Pembrokeshire is in the Dyfi Estuary over 50 miles away in Mid Wales, where no escapes have been reported.
‘It’s much more likely the beaver has been released in Pembrokeshire by a determined rewilder’, the landowners added.
Since their reintroduction to the country in Argyll in 2009, beaver numbers have been increasing across the UK through enclosed colonies set up by various wildlife trusts.
But this is only the fourth time a beaver has been found living wild in Britain.
Other wild populations were discovered in Scotland’s Tay-Forth catchment area, in East Devon’s River Otter and on the Avon near Bristol.
A similar beaver discovery was made in East Devon in 2014, despite there being no reintroduction trials in the area.
Initially, DEFRA planned to remove the beavers, but the Devon Wildlife Trust persuaded them to allow England’s first wild beaver trial.
The trial was successful and in 2020 DEFRA announced the beavers could stay. In October 2022, beavers were protected by law in England.
But in Wales, where environmental law-making is devolved, no such protection exists, and the discovery of a wild beaver could now force the Welsh Government to legislate on the issue.
The Pembrokeshire landowners continued: ‘It looks like the Welsh Government need to legislate or they’ll be in danger of trying to close the stable door after the horse has bolted.
‘With so many enclosed beavers around Britain, you wonder how long it will be before there are more escapees.’
The animals, which can live for as long as ten years and weigh up to 30kg, are not universally popular.
In Scotland, where beavers have been so successful many farmers feel their livelihoods are being threatened because beaver dams can flood valuable farmland.
The Scottish Government has even begun issuing licenses to cull them.
But rewilders call this ‘ecosystem engineering’ and highlight the positive effects of wetland creation, providing habitat for animals like otters, water voles, toads, frogs and wildfowl.
This is what makes beavers a ‘keystone species’, in other words, they are the glue that holds a habitat together.
One of Kelowna’s urban beavers is back splish-splashing after being rescued with an injured tail.
The beaver was captured from the Rotary Park Marsh on April 5, after a pedestrian noticed the sick-looking critter and contacted the Interior Wildlife Rehabilitation Society (IWRS).
The volunteers jumped into action and took the beaver to a vet to have the abscess drained. While waking up from the sedation, the beaver was given carrots and sweet potato, but she is now back on her regular diet of ‘browse’ such as twigs and other high-growing vegetation, said Eva Hartmann, founder of IWRS and registered veterinarian technician.
Everyday volunteers head out to the bush and pick twigs for the beaver to snack on.
Beavers munch on the tissue layer found just under the bark. Hartmann said the downtown girl in the IWRS’ care only likes to snack on poplar trees. The beaver spat out the Saskatoon berry bush and pine tree twigs that were collected for her. Hartmann laughed and said that she knew beavers preferred poplar and willow trees, but didn’t realize how picky they could be.
A new video was released from the Beaver Institute that is fantastic but they are going to tweak it and re-release it at a later date for now. Just know good things are afoot. Sneak preview my favorite line is that your local beaver pond is your rainforest, and your coral reef. How smart is that? This is a special edit from heidi who came home yesterday and is trying to figure things out.
An interview with Suzanne Fouty and Adam Bronstein
Suzanne Fouty has been exploring the issues of water and the return of wolves in the West for over 30 years, the contributions made by beaver to ecosystems for over 25 years, and the synergy between beavers and wolves in restoring stream systems for over 10 years.
Her work on wolves began in 1990 at Yosemite Institute where she gave weekly presentations to students on the pending return of wolves to the West and some of the social questions in play related to livestock grazing and ranching on public lands and wolves.
She worked for the Forest Service in eastern Oregon as a hydrologist and soils specialist for almost 16 years before retiring in 2018. Since retiring she has been deeply involved in five recent efforts to close federally-managed public lands in Oregon to beaver trapping and hunting as a proactive response to climate change and biodiversity loss.
Suzanne was included in the PBS Nature episode “Leave it to Beavers” and featured in the film “The Beaver Believers.” Her writing and presentations have been primarily for the general public to share how beavers and wolves contribute to preparing communities for climate change via stream and wetland restoration, and the social and political obstacles getting in the way of those contributions.
Adam Bronstein is the director for Oregon and Nevada with Western Watersheds Project, a non-profit conservation organization working to protect and restore public lands and wildlife throughout the West. He is the host of Wilderness Podcast and also serves as board president of the Gallatin Yellowstone Wilderness Alliance in Bozeman, Montana, working to protect the remaining wilderness-quality lands of the Custer-Gallatin National Forest.

The humble beaver could become one of America’s hardest working allies in the race to adapt to climate change.
Beavers are natural engineers. They instinctively build dams and canals of water to keep themselves safe because they’re clumsy on land. And capturing that water creates ecosystems for other animals to survive, earning beavers the moniker of a “keystone species.”
A growing movement of nonprofits, experts and government agencies see a potential to take a lesson from beavers’ natural engineering prowess to capture more of that water for the places that desperately need it.
“Beavers benefit a lot of things in the context of climate change,” Emily Fairfax, assistant professor of environmental science and resource management at California State University Channel Islands, told ABC News.
“The ones that are most directly sort of in our eyesight right now is the beavers’ ability to protect ecosystems during droughts, during floods, during wildfires, during extreme disturbances. And in those patches of habitat that they’re protecting, there’s a huge amount of biodiversity”
This heat wave, and the threat of wildfires, makes me appreciate #beaver engineered fire refugia even more. This complex is on Little Last Chance Creek up in N. California – in some ways these ponds were a "little last chance" for all the critters during the fire here last year. pic.twitter.com/badIjn55Kx
In addition to storing water, Fairfax’s research has shown that areas with beaver dams are more resilient to wildfires because the plants and trees are so wet they don’t burn. And she said they could help capture water from extreme rain events like the atmospheric rivers in California to be accessed by those water systems later.
“Beavers sort of figured this out instinctually over 7 million years of evolution that their dams and their canals work because they take the whole hydrologic cycle and they just make it more stable, more consistent,” she said.
Beavers haven’t always been recognized for their benefits. Fur trapping dramatically reduced the population starting in the 1700s and even today beavers are sometimes seen as a nuisance and killed. The animals are sometimes relocated away from urban areas where their dams could cause disruptions and flooding, which experts like Fairfax said can sometimes be appropriate but is not always the right approach.
Instead of treating them like pests, groups like the National Forest Foundation are looking to take a lesson from beavers’ work to find a nature-based approach to adapt to impacts of climate change like worsening drought conditions.
“There’s a lot of streams and headwaters to the Colorado River that used to run perennially, year-round, that we now see have stopped. And so we might be able to, as we do enough of these, turn some of those stream flows back on on an annual basis. And seeing those regular additions throughout the year could have huge benefits to the system as a whole,” said Marcus Selig, chief conservation officer with the National Forest Foundation.
Photos show an area near the headwaters of the Colorado River before and after the installation of beaver dam analogs by the National Forest Foundation.
The National Forest Foundation is a nonprofit created by Congress to support national forests. Selig said their work building man-made “beaver dam analogs” can help capture more water in the Colorado River, which has been struggling with historically low water levels after more than two decades of drought.
The analogs are a manmade version of what beavers would instinctively build, using sticks and mud to create a natural barrier to slow water down and create a wetland area that feeds into the river.
“The work we do with beaver dam analogs and low-tech process-based restoration is holding that water in the higher elevations as the snow melts and so that it can be released slowly throughout the year, giving more continuous, dependable flows to downstream users,” Selig said, adding that it can help communities downstream receive water more consistently.
“Our big dream is that we can restore every headwater, every watershed that feeds into the Colorado River on national forest lands. And so we’re working on creating that pipeline of projects right now,” he added.
Selig said this kind of work hasn’t been scaled up enough to identify how much of a larger impact it could have and they still need more funding to do so, but said the foundation is working with the U.S. Forest Service to add projects in 14 different national forests around the Colorado River.
Fairfax said river systems like the Colorado have lost a lot of the wetlands that would have existed 200 years ago so replicating them either by creating man-made beaver dams or relocating beavers to streams in the area can help make the river more resilient to the impacts of climate change.
“Bringing back beavers and restoring the wetlands, it’s not like we’re introducing something new to save the Colorado River Basin. We’re just trying to get it back to the state it was in when it was stable and when it was healthier,” she said.
Similar projects are growing around the country, some with support from states or the federal government. California has dedicated $1.6 million to hire staff to start similar projects in the state.
A key legislative committee has approved new limits on killing beavers in Oregon, which will now be considered by the full House. A last-minute amendment allows beavers to be killed without a permit during emergencies, but the Oregon Farm Bureau remains opposed to the bill.
A proposal to strengthen Oregon’s beaver protections is headed for a House floor vote after a last-minute amendment secured its unanimous approval by a key committee.
Beavers would no longer be considered predatory animals under House Bill 3464, allowing state wildlife officials to manage the species on private lands instead of farm regulators.
Supporters of the bill argue that as “nature’s engineers,” beavers make improvements to waterways that are particularly valuable as the state faces increasing droughts and wildfires.
“Despite these clear benefits, Oregon law currently allows unlimited beaver killing year-round, including during breeding and rearing season, without a permit — even if the beaver is not causing any damage,” said Rep. Pam Marsh, D-Ashland.
Under the original version of HB 3464, the changed designation meant landowners would need to obtain permits to kill beavers. Such permits aren’t required for predatory animals, including feral swine, coyotes and rodents.
While the bill would ensure “lethal removal is still an option,” permits would allow beaver populations to be managed and tracked by the state’s Department of Fish and Wildlife similarly to fur-bearing animals, Marsh said.
“This is just another species that will be added to the list,” she said.
Though the bill’s proponents claim these permits can be obtained over email free-of-charge within about 30 minutes, the new requirement didn’t sit well with critics who said they’d impose a time-consuming barrier during pending disasters.
If an irrigation canal is failing, for example, urgent repairs may require taking the life of a beaver to prevent flooding that endangers people and property, said Gene Souza, executive director of the Klamath Irrigation District.
“There are emergency situations that occur at two in the morning, sometimes on Sundays, sometimes on Saturdays,” Souza said.
The bill’s supporters acknowledged that beavers can be damaging but said their usefulness justified regulating their lethal removal more strictly.
Beaver dams reconnect creeks and streams with their floodplains, buffering against drought effects and creating “refugia” that shelter wildlife, livestock and habitat from wildfires, according to proponents.
Unlike human efforts to restore impaired waterways, which can take significant investments over decades, beavers can perform the work within years without charging a single dollar, said Emily Fairfax, an assistant professor of environmental science at California State University.
It will be an improvement but sheesh -lethal removal?- we’re not really that difficult to move to where we’re wanted! Read or listen the whole report.

When Dr. Richard Lanman purchased his Los Altos home in the 1980s, Adobe Creek, which snaked behind his backyard, was at best a rivulet of trickling water in the summer. In good winters, a rushing torrent carried logs, leaves, silt and debris out to San Francisco Bay.
But his neighborhood’s old-timers remembered Adobe Creek as a year-round fly-fishing paradise until the 1950s. His 80-year-old neighbor Herb Bickell told Lanman in 1987 that he’d caught fish from his backyard.
“So too, did Sen. Alan Cranston, who lived just a little bit upstream from us,” Lanman said.
But now Adobe Creek is dry for half the year, and there are no fish. Bickell wondered why the creek had undergone such a drastic change.
“Maybe there were beavers,” said Lanman, a Los Altos-based physician scientist, historical ecologist and president of the Institute of Historical Ecology. “One of my theories is there were beaver ponds or percolation ponds that raised the water table so that in our dry season, when the water table is high enough, it recharges the creek.”
Lanman’s urge to answer that question became an additional career in ecological history, leading to research into the Midpeninsula’s and south San Francisco Bay’s missing links. Now he and his colleagues have published groundbreaking findings confirming the past existence of local populations of Chinook salmon, American beavers and Tule elk.
They’ve also suggested possible ways to bring the species back.
Little is understood about California’s historical ecology prior to the arrival of the Europeans, whose actions wiped out animal populations, he said.
“A lot of the species are already gone by the time the U.S. takes California from Mexico, who had just taken over from Spain,” Lanman said.
Zoological records from the time were also not plentiful.

Hunting for beavers

Another species that has intrigued Lanman are beavers.
Scientists traditionally dismissed the beaver as a nonnative to the Bay Area, he said. This stance was largely influenced by the 1937 book “Fur-bearing Mammals of California,” written by Joseph Grinnell. Grinnell was the University of California, Berkeley’s first director of its Museum of Vertebrate Zoology and one of the most well-known figures in American natural history in the early half of the 20th century. Grinnell maintained beavers never lived in the Coast Range and Sierra Nevada watersheds, Lanman said.
“And then I met an archaeologist who found a buried beaver dam in the Sierra Nevada. And that was my first historical ecology publication in 2012. It was a buried beaver dam about 12 feet down, and (we) radiocarbon dated the sticks and it showed this dam had been there for hundreds of years and was rebuilt probably by successive generations of beavers,” Lanman said.
“But it ends around 1850 by radiocarbon dating. Of course, 1850 is the gold rush right? And that’s when all these Anglo Americans hunted everything out,” he said.
By the time Grinnell wrote his book in 1937, the beavers were gone.
“He’s suffering from what we call ‘shifting baseline syndrome,’ where you think the way things look when you were born is the way things always were,” Lanman said.
Lanman searched literature, historical accounts and archaeological evidence for the beaver’s historical presence in local waterways. He didn’t find any beaver specimens in early California museum records.
“But if you look in the Smithsonian, it turns out there’s a beaver skull collected on Saratoga Creek around 1855. So that was the first physical evidence of beaver in the Bay Area in a tributary of the south bay,” he said.
Lanman and colleagues published the findings in the fall 2013 California Fish and Game journal. They studied museum specimens, zooarchaeology specimens, place names, documents and words for “beaver” in local California Native languages for evidence of beavers throughout western California from the California-Oregon border to San Diego and to the southern Sierra Nevada.
The researchers found evidence all over the state. In the Bay Area alone, they found 24 records from Healdsburg to Saratoga and from Bodega Bay to Fremont. These included a zooarchaeological specimen from the Emeryville Shellmound, which included a 1,500- to 1,700-year-old beaver tooth, a more than 2,000-year-old beaver incisor and three beaver bones, dating between 700 and 2,600 years old.
Historical literature also abounds with references to beaver hunts and acquisitions from Native Americans. A 1776 account of the second De Anza Expedition noted that Native Californians wore capes of beaver pelts and pelican feathers.
The famed frontiersman Kit Carson held rights in the 1840s to trap them in the east bay. In Santa Clara County, a 1962 study found historical evidence of beavers “in small numbers at least” in Coyote Creek in Santa Clara County among other places, Lanman and his colleagues noted.
How those beavers might have traveled around the bay and up tributaries in Santa Clara County and perhaps San Mateo County is beginning to be understood due to the presence and growing population of reintroduced beavers.
The semi-aquatic rodents were introduced in the early 1980s to upper Los Gatos Creek near Lexington Reservoir and have been slowly making their way northward. The beavers have expanded their territory by swimming up San Francisco Bay to Coyote Creek to the east; the San Tomas Aquino Creek where it reaches the Sunnyvale Water Pollution Control Ponds; Moffett Gate; and Charleston Slough, just east of the Adobe Creek levee, according to Lanman.
Nine years after the beavers research was published, Palo Alto resident Bill Leikam, co-founder and board president of the Urban Wildlife Research Project and native gray-fox expert, documented the first modern evidence of beavers in a remote section of Palo Alto’s Matadero Creek, where he found two beavers in April 2022. If they are a compatible pair, they could begin colonizing the creek and perhaps slowly lead to a population that would move on to other local creeks, Lanman and Leikam said in November.
Lanman is eager to see how beavers might help revive locally collapsing fish populations. Flood control efforts have altered natural channels, such as San Francisquito Creek, which is dammed by Searsville, the Guadalupe River in San Jose and Palo Alto’s Adobe Creek. Lanman wondered how changes to those habitats have affected fish species such as Chinook and steelhead — and whether nature could reverse the damage.
“Beavers are the one thing we haven’t tried. They have these important ecosystem benefits, not just for our trout and salmon, but for all kinds of critters: red-legged frogs that are federally endangered; birds that are federally endangered that depend on the hunt over water and bats that hunt over water,” he said during a November interview.

International Beaver Day was first celebrated in 2009, after being created by a nonprofit group called Beavers: Wetlands & Wildlife. The group chose April 7 as the date because it is the birthday of Dorothy Richards (1894-1985), a woman who had studied beavers for almost 50 years at the Beaversprite Sanctuary in the Adirondack Mountains of New York. She had been an inspiration for Beavers: Wetlands & Wildlife, and the group’s first work was to finish reforming management of the 1,300-acre Beaversprite Sanctuary. They also have worked to stop anti-beaver legislation from being passed in several states, and have worked to find solutions to human and beaver conflicts. Eventually, they became an internationally recognized authority on beavers. In the first year of International Beaver Day, they donated almost 1,000 copies of the teachers’ edition of their DVD Coexisting with Beavers to schools.
There’s more about our day from the site above but you might have seen some of it already. What’s happening now really shows that past efforts to get the word out about how valuable we are is paying off!

In ecosystems, all species interact with each other and their environment. However, some species have a much greater influence than others. Certain plants or animals are able to greatly modify their landscape through just their mere presence. This makes them part of the group know as “ecosystem engineers.”
One of the best known examples of an ecosystem engineer is the beaver. By building dams, beavers change the flow of rivers and transform terrestrial ecosystems into wetlands. This leads to a whole cascade of processes and the arrival of new animals.
Although the individual cases of ecosystem engineers helping biodiversity are well documented, the mechanisms at work are not yet well understood. Scientists from UNIL have developed a guide for predicting and measuring the influence of species on ecosystems under different conditions. The aim of the guide is to include “ecosystem engineers” in the process of biodiversity conservation and ecosystem maintenance. The team’s review is published in Functional Ecology.
To establish this framework, the scientists proceeded in several stages. First, knowledge and literature about the known ecosystem engineers was collected. Next, the team developed a comprehensive framework to model and quantify the effects of the species. Finally, a procedure for including these natural regulators as much as possible in the field was created.
Gianalberto Losapio is the lead author of the study and a researcher at the faculty of Geosciences and Environment at UNIL. He is also affiliated with the University of Milan. He said, “This guide is intended to help specialists and communities ask themselves the right questions when setting up conservation programs. For example: What is the goal? What are the characteristics of the terrain, as well as the spatial context?”
The guide also provides tools to assess the impact of the actions carried out so that they can be adapted if necessary. “Some restoration projects end up being abandoned because introduced species cannot survive,” adds Losapio. “We believe a comprehensive approach is more likely to succeed.”
Burlington, Vt. – Ahead of International Beaver Day (April 7), PETA sent a letter this morning to Champlain College President Alex Hernandez, appealing to him to slap a fur ban on campus so as to protect beavers just like the school’s own beloved mascot, Chauncey.
PETA points out that tens of thousands of beavers are killed every year and that, as Champlain College itself points out, they were once on the verge of extinction in North America due to hunting for their pelts. With a ban, the school could help protect beavers and other animals still trapped and killed for their fur, joining Kingston University in London and the many cities that are also implementing or considering fur bans, and further the college’s mission to advance society and encourage students to help create a better world for all.
“Beavers are caught in steel-jaw traps, which clamp down with bone-breaking force, causing excruciating pain and a slow death,” writes PETA President Ingrid Newkirk. “Please help end cruelty to beavers by informing students and staff members about the threats these animals face and by establishing a fur-free campus.”
PETA’s letter to Hernandez follows.
April 5, 2023
Alex Hernandez
President
Champlain College
Dear President Hernandez:
I’m writing on behalf of People for the Ethical Treatment of Animals—PETA entities have more than 9 million members and supporters globally, including many thousands across Vermont—ahead of International Beaver Day on Friday, April 7, with a dam good request that would help protect beavers like Champlain’s beloved mascot, Chauncey: Will you please ban fur on campus? This step would not only further the college’s mission to advance society and encourage students to help create a better world for all but also help protect beavers and other animals who are trapped and killed for their fur.
As you likely already know, beavers are intelligent and resourceful animals. They’re well gnawn for building dams to create ponds that offer refuge from predators and space for food storage. They also construct lodges that provide shelter and a safe place to raise their young. They’re great swimmers, and their fur is naturally oily and waterproof, which helps them keep dry and warm, even when submerged for a very long time. They’re also among the few animals who can alter their surroundings to produce a suitable home. The dams they make generate wetlands, which are vital ecosystems for many species.
Tens of thousands of beavers are killed every year, often in response to their natural dam-building efforts or so they can be used for their fur. Champlain College even points out that beavers were once nearly extinct in North America due to hunting. To trap beavers, humans often use steel-jaw traps, which clamp together with bone-breaking force, causing excruciating pain. Beavers are also often strangled in neck snares and crushed in body-gripping traps, which are barbaric devices with metal bars designed to slam shut on an animal’s body. Some traps are designed to hold beavers underwater until they drown. But since they’re used to holding their breath while they dive for long periods, death by drowning is a slow, agonizing process for them.
Please help end cruelty to beavers by informing students and staff members about the threats these animals face and by establishing a fur-free campus. Many U.S. cities have already implemented bans on fur sales, and various institutions of higher learning are considering fur bans. Your efforts to help animals would beavery impactful. Thank you for your consideration. We look forward to hearing that Champlain will be a leader on this important issue.
Very truly yours,
Ingrid Newkirk
President
We are intelligent and resourceful and do do well at gnawing trees to sustain us and make our dams, but I’m not sure if the mention above of “being well gnawn” is a punny insert or auto-correct glitch. It sorta fits though. . .

The U.S. government is looking to an unlikely rodent in an effort to repair ravaged riparian ecosystems, and it might be working.
Beavers are one of the odder species, in terms of appearance. With their long buckteeth, paddle tail and rounded shape, they don’t often attract sympathy from the owners of the land they choose to settle down on.
Due to unregulated trapping in the 1800s, beavers were largely eradicated from the U.S. This had cascading effects on the ecosystems they once called home. Beavers, as “ecosystem engineers,” change their environment in ways that promote a healthy ecosystem. With beavers gone, the riparian, or water based, ecosystems they frequented were in trouble.
Many other animals rely on the work beavers do to remain healthy. Without beavers, fish populations, predators, birds, amphibians and even the plants lining water banks were suffering.
Since 2008 the Okanogan-Wenatchee National Forest has been reintroducing beavers to various areas in order to promote riparian health. According to the United States Department of Agriculture, the project has documented an increase in salmonid spawning and rearing as a result of the beavers’ presence.
In Idaho there are between 50 and 75 beaver restoration projects currently operational. These projects either directly introduce beavers to damaged riparian areas or have biologists build dam-like structures in order to encourage beaver populations to return to those areas.
The U.S. has a history of killing off vital species, directly resulting in whole ecosystems decaying; a cursory examination of the history at Yellowstone National Park can attest to that. The eradication of wolves, grizzly bears, mountain lions and, of course, beavers have all resulted in the lack of riparian vegetation, predatory species and healthy landscapes.
It brings hope to the environmental community seeing these restoration projects underway, reversing the damage once done to the American landscape. Recent legislation, like Idaho’s SB 1211 and Utah’s HB 469, attempt to undo some of those efforts, but biologists and conservationists are not so easily deterred.
The beaver represents a great success in conservation; once nearly extinct, there are now almost 15 million in North America alone thanks to supremely dedicated conservationists.

But coexistence is key. We just want to get along without hurting anyone. So maybe you can help out these friendly folks.
Humans often kill beavers when their damming and tree-chewing behaviors cause problems such as flooding and destroyed vegetation. This approach is ineffective because new beavers will soon move into the empty habitat. Lethal trapping, dam destruction, and culvert unclogging are only temporary solutions that, in the long-run, are expensive and unsustainable.
How is coexistence possible?
Beavers and the wetland habitats they create are beneficial to people, plants, animals, and entire landscapes and watersheds. We believe it is possible for people to share land with live beavers while addressing flooding and tree-chewing problems using long-term, cost-effective solutions.
Got some images of kids playing beaver at the recent SLO County Beaver Festival.
Beavers from Space launched April 4th on the Zooniverse. The citizens science project uses satellite imagery to uncover beaver habitat in Canada. Read on below to learn more about how you can help out.
Become a dam detective by searching satellite imagery for signs of beavers on the landscape!
Despite the cultural and ecological importance of ksisskstaki (beaver) little is known about their presence in Alberta’s streams and rivers. By searching through satellite imagery for beaver dams and lodges in the waterways of the Kainai Nation (Blood Tribe) in southern Alberta, Beavers from Space seeks to determine where beavers are present on the landscape and where they are not. Volunteers will search through imagery of over 7,000 kilometres (4,300 miles) of streams within the study area, a task that would be overwhelming and expensive to undertake with field work alone. This information, in combination with field work data, will inform riparian (river ecosystem) restoration locations, which may include the installation of beaver dam analogues. Beaver dam analogues are a proven riparian restoration technique that improves watershed health and function by mimicking the work of beavers.
Our study area is focused on the 3 watersheds (outlined in black below) that the Kainai Nation (Blood Tribe) reservation and timber limit are located in (outlined in red below). Generally, this area stretches west from Lethbridge, Alberta, to the British Columbia border, and includes Waterton Lakes National Park. The study area is just north of the Canadian-American border in the State of Montana.
By reviewing satellite imagery for beaver dams, you can help us understand where beavers are present in our watershed or where beaver-mediated restoration could occur where beavers are absent. We anticipate a relatively low density of beavers on this landscape, which is why we need your help to search every stream in the study area.
Dam neat project if you ask me! Click this link for a lot more information.
There was a bit of news from The First Annual SLO County Beaver Festival. It went well with around a thousand attendees over the day. A good time was had by all and especially the kids who got to build dams out of mud and sticks! There is also a fun video of Cooper Lienhart joining The Loving Mosh to sing Go Little Beaver Go at the Festival on April 1st, 2023.
Oh! One more thing. The Cambridge Filmworks people got rid of the darn nutria photo that I told them about! They found an image of a handsome European cousin to head the article like I hoped they would. Yeah!
It’s not clear yet whether this is one beaver who escaped from elsewhere or a pair who were released by rewilders, but it sounds like a good dam move to me!
