Members of a Canadian conservation organization are working on a project to increase biodiversity and healthy wetlands in British Columbia with the help of beavers. Ducks Unlimited Canada is mapping areas in the province where beavers can replace artificial dams once they’ve been decommissioned.
“Beavers are a keystone species,” said Jen Rogers, a master’s student at Simon Fraser University working with Ducks Unlimited Canada. “They’re considered ecosystem engineers.”
“The team is currently assessing areas across the province where beavers were historically over-trapped to make room for engineered dams.”
Many of those artificial structures are now decades old and due to be replaced. The team hopes to restore the beaver population, not only to replace the dams but to provide the added value of restoring biological diversity to the landscape.
Roger Dunlop, a biologist and the manager of lands and natural resources for the Mowachaht/Muchalaht First Nation, says bringing the beavers back would have a positive domino effect on other parts of the ecosystem.
He has been monitoring Gold River water levels since the 1950s and is concerned about the increasingly low levels. He blames the change on reforestation.
“We’ve replaced [old-growth forests] with young, rapidly growing super tree plantations that require much more water,” said Dunlop. The water loss has, in turn, caused a decline in freshwater species, and as warmer months approach, the risk of drought increases.
He says that reintroducing beavers can “rehydrate the landscape,” giving it a break from overuse. Beaver ponds help surrounding land absorb water, allowing it to resist droughts and floods.
“If you think about it, forestry in B.C. is really overgrazing, just at a larger scale,” said Dunlop. “The blades of grass are just trees, right?”
Dunlop says his expertise as a biologist informs his work, as does his identity as a member of the Mowachaht/Muchalaht First Nation. He says First Nations communities involving themselves in biodiversity work is important.
“They’re exercising their right to take better management control of this particular landscape that’s really been over-harvested,” he said.
Chattanooga beavers are especially eager this year to acquire building materials for their dams from Ross’s Landing, where the city’s Parks and Outdoors Department is taking unusual measures to manage the damage to the trees along the riverfront.
The parks team recently planted new trees along the riverfront at Ross’s Landing, and team members chose to plant bald cypress trees because beavers usually leave those alone. But the trees repeatedly were being damaged or taken down completely, sometimes within 24 hours of planting, city of Chattanooga Parks and Outdoors Communications and Marketing Director Brian Smith said in an email.
The beavers’ chewing can damage or kill the trees and cause them to fall onto the nearby playground and path, making them a safety hazard, he said.
The parks team tried several methods to deter the beavers from gnawing on the trees. Team members put fences around them, but the beavers climbed the fences and continued to chew. Then they put hot sauce on the trees, which kept the beavers from chewing them, but the sauce washed off in the rain.
Park staff cannot trap and relocate the beavers, because according to state law, beavers must be euthanized if trapped, Smith said.
The best solution they settled on — which is recommended by the Humane Society of the United States — was to paint the trees using nontoxic interior latex paint diluted with water and mixed with sand, which irritates the beavers’ teeth enough to encourage them to look elsewhere for a snack.
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.
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 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.

I knew it would happen. I just knew if I worked and worked and waited and waited and advertised for beavers over and over again someday we’d see a beaver-believing article from Charlotte North Carolina. I knew it would happen. I just didn’t know it would happen last night.
CHARLOTTE, NC – A group of residents in the Thornhill neighborhood in South Charlotte say the home owners association trapped and killed a family of beavers without seeking humane solutions.
The pond through the neighborhood is a central point of the Thornhill community. It’s where kids can play and people can walk. For the last several months; it’s also been home to a family of beavers.
“They do things for us. They clear the water. They reduce sediment,” said Angela Hynum. Hynum is a Thornhill resident and wildlife advocate.(more…)
Once upon a time I was the new kid on the block trying to save beavers. Those days are (thankfully) history. Now there are beaver disciples all across the land. Making huge difference. This is the recent post from Rachel Siegel who was motivated to save the beavers when her HOA wanted them killed in Glanview Park in Illinois. She started the facebook page Glenview Beavers fan club, republished our urban guidebook for their state and now has become a nonprofit under ISI just like us.
I have emerged unscathed from my meeting with the IEPA today! With the help of Representative Jen Gong-Gershowitz, I was able to make a polished pitch about the role that process-based restoration (and beavers!) can play in improving our water quality and creating floodwater storage capacity.
We left the meeting with a couple of action items, including setting up a meeting with staff at the IDNR. So in the meantime, I will continue to work on setting up my new organization, the Illinois Beaver Alliance, which is a fiscally sponsored project of Inquiring Systems, Inc. , and thus has nonprofit status.The mission of the Illinois Beaver Alliance is to improve the health and function of Illinois watersheds, which will increase climate resilience, improve water quality, increase biodiversity, and create floodwater storage capacity; and to educate the public about the ecological importance of beavers and the modern tools for resolving human-beaver conflicts. I’ll tell you more about it soon!
Tomorrow we have our meeting with the Village of Glenview and then I am going downtown with Donald Hey of Wetlands Research to pitch nutrient farming (or water quality credit farming) to a prominent Clean Water Act attorney.
Did you catch all that? She presented her position to her state representative and is now going to meet with fish and game a water attorney. Is your mind blown completely? Beavers: The Next Generation has some fine recognition of our buddy Rusty Cohn in the County RCD Monthly Newsletter.
We are 100% certain that at least some of you know our July Conservation Champion, Rusty Cohn. If you’re on Facebook or NextDoor, you may know him as the one sharing photos of local cute baby animals: the downtown Napa beavers!
Rusty does a great job inspiring us to treasure the wildlife that we have in our downtown. In addition to sharing his photos, he also shares stories and behaviors he observes while photographing these creatures. So who is Rusty?
Rusty has been in Napa 10 years and says his favorite part about being here is that it is a small town with a slower pace of life that is matched with a great diversity of wildlife so close by. After visiting his daughter here, he and his wife fell in love with the area and decided to move here once he retired. Now, Rusty keeps busy with several hobbies (including photographing local wildlife) and walking his dog Toby.
After first noticing a beaver dam next to Hawthorne Suites Hotel while out walking, he became fascinated with beavers and all of the other wildlife that were living in and near the beaver ponds. Rusty says his favorite part about photographing and sharing the animals found in our urban landscapes is that you never know what you might see next. He finds it exciting to observe the variety of wildlife, and he hopes his photos encourage others to become more interested in viewing and protecting the diverse wildlife of Napa County.
One thing Rusty wants us all to know: “Napa is a wonderland of biodiversity, get outside and enjoy it!”
Not only does Rusty share photos on Facebook and NextDoor, he also shares videos on his YouTube page!
We love community members who are excited about seeing and sharing local wildlife, and Rusty is a great example of that. Thanks for helping us get to know the nature in our own neighborhoods!
WHOO HOO! Rusty has been a good friend and supporter of Worth A Dam and helped out at our festivals AND earthday! I’m so happy his hard work is getting noticed.
Meanwhile I my hard work is apparently only worth stealing because my OpEd was stolen again by a letter to the editor for the Eugene Weekly. Hope my words are having fun being kidnapped!
Oregon is killing off one of nature’s best firefighters.
Last summer Oregon endured the single most flammable year in modern history. Record-setting fire after record-setting fire churned through the state, yet once again we continue to ignore or even kill the water-saving firefighter who would work for free to protect us: the beaver.
Recent research, published under the title “Smokey the Beaver,” found beaver complexes were three times more resistant to wildfire than similar areas without beaver. Beaver habitat, with its dams, ponds and canals, showed less wildfire damage than un-beavered streams. In keeping water on the landscape, beavers reduce fire, mitigate drought and recharge groundwater.
Beavers save water and reduce the risk and severity of wildfire. They do it all day, every day, at zero taxpayer expense. Their ponds have been consistently shown to increase biodiversity from stoneflies to steelhead. Beaver ponds help fish survive at a time when the Pacific coast is hemorrhaging salmon.
Our own self-interest dictates our attention. Yet Oregon isn’t learning.
