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

It always looks so good to relocate beavers.  So much better than killing them.

Beaver believers: Native Americans promote resurgence of ‘nature’s engineers’

Beavers are often considered “nuisance” animals on the US west coast and, if captured, are destroyed by animal control companies.

But the beaver picked up by Molly Alves is to be transported to Alves’ employers, the Tulalip Tribes, a nation in Washington’s western corner. This Native American community, and others, are at the vanguard of the “beaver believer” movement, which holds that the rodents can play an essential role in maintaining healthy landscapes.

Beavers are known as nature’s engineers, due to their dam-building habits. For decades they have been hated by landowners, who dislike the animals’ tendency to fell trees and flood areas. However, their dams – although seen by some as a nuisance – help control the quantity and quality of water flow, while their ponds create habitat for numerous plants and animal species, including fish.

It gives me such a soft fuzzy feeling to read that somewhere beavers are so valued that they will move them rather than kill them. But still, new beavers will just be drawn to that spot and the whole thing will happen again. Better to let them stay like we did in Martinez and make changes so that everyone can be happy.

Back in 2018, Washington’s Cowlitz Indian Tribe started on an ambitious project: to reintroduce beavers back into the Gifford Pinchot national forest, a wild region on the slopes of the Cascade mountains, as part of efforts to reclaim indigenous land management practices. The animals had not been in the region since the 1930s, after they were trapped into near-extinction in North America during the 1800s fur trade.

In partnership with the Cascade Forest Conservancy, the tribe has spent the last two years capturing beavers from private lands, where their dams are often dynamited, and relocating them on to tribal land.

The project has been such a success that the tribe was recently awarded a grant to survey beaver habitat, mapping the impact beavers have made on the land, in order to create a relocation model for other communities in the state – and perhaps further afield.

Not this field I’m afraid. California doesn’t allow beaver relocation – except onto tribal lands where our government has no say. Once this was my dream for the state but now I just want CDFW to show landowners how to wrap trees.

I’ve become more realistic in my old age.

Interest has been spurred by California’s most intense wildfire season on record – in 2020 the state experienced five of its six largest-ever fires. Research published last year revealed beavers can be used to mitigate the spread of fire because beaver-inhabited land is simply too wet to burn.

But tribes in California have their own legal battle to wage: relocation of beavers in the state is illegal, and so communities have turned to other strategies, such as building beaver analogues – manmade dams – in order to attract the animals to their watersheds.

“Doing a full beaver reintroduction is difficult, and so we just decided to build analogues to get them to come to us instead,” says Roger Boulby, the Yurok’s watershed restorationist, who is restoring the Klamath River by physically moving the river’s path, as well as trying to bring back beavers to help boost salmon populations.

Hey if we are going to discuss beaver benefits in California can we maybe get a shout out to the beaver summit? Anyone?

Until legislation changes in California, which classes beavers as a detrimental species, the tribe is limited to building suitable environments in the hopes of attracting beavers.

“It’s unfortunate that the situation is so political but that is the case right now, given that the California department [of fish and wildlife] is reluctant to support beavers,” says Kate Lundquist, the director of the Occidental Arts and Ecology Center, a California organization that promotes biological and cultural diversity.

If projects in states like Washington go well, “it could open the door for future relocations,” says Lundquist. “We’re using these projects as pilots to show that beaver rewilding can be done in a responsible way, and hopefully that will answer some of the concerns, and ideally make it available to those not on sovereign lands.”

Ahem. Maybe if there were some kind of big meeting to discuss how beavers make a difference? A statewide “come to beavers” meeting? Like a pow-ow or a summit of some kind?


Cornwall is an amazing part of England, hanging down at the end of the Isle like a big foot dangling out of the bed at night. It has wonderful adventures at every turn, and one glorious early summer we spent every day along its winding roads finding nooks and crannies worth exploring at every turn. It is also the place where my grandfather and his parents immigrated from when the Tin mines stopped hiring. They found their way to the goldmines in Sierra City and took over from there.

It also has its first wild beavers. And hey guess who went to boarding school in Truro? This has destiny written all over it.

Cornwall tea plantation wild beaver sighting a ‘first’

A beaver which has been spotted at a Cornish tea plantation is thought to be the first in the county sighted in the wild since the creatures’ reintroduction.

The beaver was pictured feeding on the bank of the River Fal on the Tregothnan estate near Truro. Tregothnan manager Jonathon Jones said: “We are just hoping it does not have too much of an appetite for tea.” The Cornwall Beaver Project said it was “delighted” and “surprised”.

Whoa! I thought it was kind of freaky that the most famous beaver trapper was buried in Martinez. And that when I found out that Enos Mills actually CAME to Martinez. But the first wild beaver in Cornwall swimming up 7 miles from Jon’s school is pretty wild.

Now I’m getting suspicious.

Chris Jones, from the project, said he was “surprised” to hear of the wild beaver.

“We have no idea where it has come from,” he said. Mr Jones urged people to treat the creature with respect.

“I’m really excited by it and my advice is that if it is not bothering anyone, leave it alone,” he said.

 


Interesting article from Brooke Reyolds (no relation) in Annapolis Maryland, It had my attention all the way through the conclusion,

Brooke Reynolds: Do beavers have a place in modern America? | COMMENTARY

Before leather-booted colonists with their own rigid ideas of progress stepped onto the shores of America, beavers defined the landscape.

Since shortly after the last ice age ended, America’s riparian systems were defined by an intricate arrangement of seeps, bogs, wetlands, beaver dams, floodplains, and branching streams and rivers woven into a harmonious tapestry. The keystone species orchestrating this river dance was Castor canadensis, the American beaver.

Ooh now this is getting interesting. Gee I wonder what her conclusions will be?

Beavers were not only engineers, they were artists. Nearly every creek would have exhibited a chain of beaver dams, sculpting entire ecosystems of braided streams and wetlands. The natural system of beavers building and intermittently abandoning their dams provides many benefits: habitat creation, filtering pollutants, catching silt, preventing erosion, and encouraging groundwater infiltration and seepage that often results in cooler waters downstream.

Yes they did, But to be fair they probably didn’t;t have much pollution to remove in the 1799, Still, theirs was a different world than the one we inhabit today.

Before environmental regulation, demands for land resulted in building on sensitive habitat. Stormwater surface flow was sent to pipes and then out to the nearest stream, resulting in the straight, deep cuts of stream channels we see today. There was an incomplete understanding of the damage being done to floodplains, bogs, and marshes. How can we mimic the pristine ecosystems of the past in a time of anthropogenic impact?

Simply using beavers to perform the ecosystem services they once did seems like an obvious answer. However, we do not have sufficiently large beaver populations in Anne Arundel County or much of the East Coast to rely on them to restore streams to pre-colonial conditions. Dams require constant maintenance and a robust beaver population.

Underwood & Associates, a local ecosystem restoration company, created the Regenerative Stream Channel and Step Pool Stormwater Conveyance restoration methods to advance habitat recovery over time to closely approximate native ecosystems. These designs use biomimicry to achieve outcomes similar to beaver dams, incorporating a series of riffle weirs, sand seepage berms, and step pools that slow down and spread out water in a more predictable and sustainable manner than beaver impoundments. This results in the trapping and filtering of pollutants, enhanced floodplain connection, groundwater infiltration, erosion prevention, and habitat creation.

Although these systems can mimic the benefits of beavers, do these iconic mammals fit into restoration projects?

It is common for beavers to move into restoration sites after they are completed. The beavers will often begin building dams on top of existing weirs, which can raise the water level in ponds a few feet higher than restoration plans may have expected. The extra water may cause weirs to “blow out.”

A beaver-friendly restoration project must be hardy enough to accommodate the rising and falling of water levels as the beavers make their own modifications to the site. Underwood & Associates welcomes beavers that take up residence on all of our restoration sites, since our projects are created to be resilient enough to incorporate the changing conditions and fluctuations of nature.

AND it must be BEAVER FRIENDLY, Don’t forget that part. Its the rarest and the most important.,

If beavers are to have a place in the current landscape of modern America, we must make space for them. More land conservation is needed to provide ample habitat and connected stream systems for beavers to inhabit. Restoration projects should be designed with resiliency and adaptation in mind.

Non-jurisdictional (less than one acre) wetlands should rook be protected from degradation and development. Benefits would reverberate across our ecosystems if we could more clearly visualize and implement designs that re-create the knitted systems of the past where seeps and headwater streams meandered through wetlands, floodplains, and beaver impoundments. Restoration and conservation present our only opportunity to mend the modern landscape to regain a semblance of the days when beavers were the composers orchestrating the ecosystem.

Oh my goodness. What a FINE letter Brooke. We want to know who you work with because you make all the best points. I’m going to look her up right now. I think there. might be a beaver festival in her future,


My parents home in the mountains woke this. morning to the tiniest bit of snow, Not even a dusting really, More if a dusting that wilted during the night. Still it is kind if fun to know that just up the road they got a whole lot more. And up the highway still they had several inches last night./

There is a whopping headline from the Times today in the UK. It is almost horrific enough ti get pay to get past the firewall, but the first two paragraphs are bad enough Just look at this headline,

Shoot beavers if they spoil our fishing, urge anglers

Landowners and angling groups are demanding the right to shoot beavers if they cause too much damage after they were reintroduced to England’s prized chalk streams.

Last week Dorset Wildlife Trust released two beavers into an enclosure in a tributary of the River Frome, which is popular for trout and salmon fishing. Wildlife groups have ambitious plans to release dozens more to “rewild” many rivers.

It’s the photo that does it for me, Not only does it perfectly convey the exaggerate fears of anglers compared to the potential problems, by using image of a nursing mother with visible teats it means “Hey we deserve to kill mothers and babies because FISH!”

If anyway wants to spring for the account you can shoot me the rest of the article. I’m sure it only gets better from here. Although I like to imagine that somewhere in the staff of the times there is a graphic artist who knew exactly what he was doing with this photo and wanted to make the anglers look as bad as possible.

Richard Slocock, chair of the fisheries association, told The Times: “There are no apex predators for deer and there will be none for beavers so it’s up to mankind to cull them to keep them to sensible numbers.

He went on to argue that beaver dams would ruin fly fishing: “Instead of being a delightful, free flowing stream with lovely bright gravel and waving green weed and trout hanging around all over the place, you are left with a silty, semi-stagnant pond with minimal fishing interest.”

However, James Wallace, chief executive of the Beaver Trust, said damage caused by the animals could be managed without culling.

Hesalmon and trout had “evolved to jump over dams,” adding: “Beavers are native species, we have just forgotten about them. But salmon and trout haven’t forgotten about beavers. If they were in Norway they would expect to come across lots of beaver dams and once they have got over them there is a nice safe place for them to live.”

The Muskrat Council was upset by my post yesterday suggesting that the little rodents don’t engineer their environment as much as some might think. There was even objection on the beaver management facebook group where one muskrat believer posted a host of research arguing that muskrat alter the invertebrates of the watershed and provoke changes.

Okay. I’m willing to attest that muskrat varied diet results in muskrat droppings that contain fertilizers that change rivers. And I admit that sometimes swans nest on their little reed huts to lay their eggs in safety. Will that suffice? Yesterday the muskrat appreciation lobby was feeling so threatened by my post that they released this report:

Chewing underwater and the many feats of the magnificent muskrat

Can you close your lips behind your teeth? No, you can’t. Because you’re not a muskrat. Bet you can’t close your ears when you dive underwater either. There’s a lot more to the magnificent muskrat than meets the beady little eye. So much so that this is part one of a two-part series wherein Martha Foley and Dr. Curt Stager talk about muskrats.

Timing is everything. Let me know the name of your publicist, muskrats. Because we could use someone like you on our side.

In the meantime I’m just going to carry on appreciating the creatures we believe are worth a dam and post this lovely video by Sheri Harstein documenting her work with the sierra beavers.Turn the sound up and make sure you watch full screen. It’s that lovely.

Did you watch the Mars landing yesterday? It was must see TV. And no finally we might get some answers to the question posed in this 1930 issue of popular science.
