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

Month: March 2021


The beavers we met in Kalamazoo have been making full use of their unfrozen lake time. Apparently the state is so surprised beavers eat trees it’s on the news! What’s this, Emma? Impossible! The next thing you’ll be telling me is that the royal family is racist!

Busy beavers may change more than the landscape at Asylum Lake Preserve

 Clearly, this isn’t the work of a professional tree trimming service. The changing landscape of a peninsula at Asylum Lake Preserve is due to these furry creatures below that stand at about 3 feet tall.

 

“Beavers are doing what they do,” said Kathryn M. Docherty, an associate professor of biological science at Western Michigan University.

Docherty hikes Asylum Lake Preserve about once a week, and says she followed the progression of the beaver habitat there for about a year.

“It’s been really interesting to see ecological processes in action on this sort of slow time scale,” Docherty said. “I would imagine what they might start doing is dragging those trees into the water, to start building a dam across the lake to the other peninsula that comes out of semi-dry land.”

Yes it is very interesting to watch beavers. I happen to be able to testify to that personally. I since she said the beavers might build a dam I had to go see if there was an inlet that fed it. Of course there is and a string of lakes along it. Things start out so easy for a beaver in Michigan.

The dam would transform the area between the peninsulas into more of a wetland, leading to a major ecosystem change, but one that would benefit the environment there.

“What beavers tend to do, is they tend to increase ecosystem heterogeneity,” said Docherty. “So, they’ll increase the different types of habitats in an ecosystem by changing some of its structure.”

“Just be aware that these trees are in a precarious position, and they haven’t been professionally cut by a human to try to ensure human safety,” said Docherty. “They’re cut by a wild animal.”

A wild animal that according to Docherty, might ultimately lead to wildly different life at the nearby lake.

Amen to that. Keep talking and teaching Docherty. And listen up Kalamazoo because you’re in for a treat! PS if you happen to click on this video STAY for the Nicholas brothers because man-o-man are they a talent.

 


Stunning new article this morning from the California Farm Bureau Federation by reporter Bob Johnson. James Haulfler of S.A.R.S.A.S. sent it my way last night and I hope you’re sitting down because it’s a doozy.

Range managers employ beavers, benefiting forage

Issue Date: March 10, 2021

By Bob Johnson

A century and a half after their ranks were decimated to make coats and hats for fashionable Europeans, beavers are making a comeback as an energetic tool for rangeland river and creek restoration.

The new appreciation of beavers comes from a shift in thinking among specialists toward believing that slowing and spreading creek water results in more diverse habitat, better drought and flood protection, a refuge during fires—and more forage production.

“We know rivers and streams are the center of the riverscape ecosystem; we’ve been too obsessed with managing them as channels,” said Joe Wheaton, Utah State University associate professor of watershed sciences.

Wheaton, a leading specialist in the low-tech approach to riparian restoration, joined the virtual California Rangeland Coalition Summit, as researchers and ranchers discussed efforts to mimic beavers in making land near creeks and rivers more diverse and productive.

Wow. In California! Thanks Joe. Wouldn’t it be amazing if people who cared about farms and ranchlands cared about beavers? And hey they stole our name. Hrmph.

“We use beaver dam analogues, which mimic and promote beaver dam restoration,” Wheaton said. “The process is wood accumulation, which makes for a healthier riverscape.”

Wheaton worked extensively with an Idaho rancher, who moved his cattle to take advantage of forage in the more marginal areas during the wet season and away from ground near Birch Creek.

The warm weather forage refuge near the creek expanded exponentially, Wheaton said, after the rancher put up a few beaver dam analogues—low-tech and low-cost, temporary structures to spread the water—and let the real beavers come in and finish the job of making the forage-producing wetland larger and more diverse.

Oh I knew it would all come down to self interest. If beavers are in California’s self interest we stand a real chance.

“Traditional stream channel movement emphasized diesel and rocks to stabilize the channel,” said Damion Ciotti, restoration biologist for the U.S. Fish and Wildlife Services in Auburn. “We were not achieving our goal of increasing migratory birds and fish.”

Ciotti helped lead the Doty Ravine restoration project in Placer County, where selective grazing of invasive plants played an essential role in restoring the riparian ecosystem.

That project largely abandoned the use of heavy equipment to quickly clear the creek, in favor of the more process-oriented approach of slowing and spreading the water and letting the beavers do their work.

“The beavers are teaching us a ton about working with the stream system,” Ciotti said.

Oh and where have I seen both men’s name before? That’s right on the schedule for the California beaver summit!!!

The central lesson has been to stop thinking of the creek as a channel to move water quickly and uniformly, he said, and start thinking of it as the center of an ecosystem that spreads out to include habitat for migratory birds, fish and grazing livestock.

“We want to increase the productivity of fish and migratory birds, and the key to that is connectivity of the floodplain,” Ciotti said. “We saw an incredible increase in bird populations, and we saw salmon out there, all while grazing continued.”

When fourth-generation rancher and University of California Cooperative Extension livestock and natural resources advisor emeritus Glenn Nader took on the job of restoring the Witcher Creek Ranch property in Modoc County, he decided he would do well to rely on people with a range of expertise.

“I may think I know what I need for cows, but how does that work for other species?” Nader said. “You need a multi-discipline team.”

Wow that’s really amazing. I didn’t know any of these groups. But I saw a few of them signed up for the conference and wondered.

Part of that team came from Point Blue, a Petaluma-based group of 160 scientists who work with ranchers, farmers, fishers and other land and water managers to bring their expertise to conservation and restoration projects.

Nader was a couple decades into his project at Witcher Creek Ranch when scientists from Point Blue advised him about the role beavers could play in restoring the creek ecosystem.

“Thanks to Point Blue for coming in and enlightening us about beavers and beaver dam analogues,” Nader said.

The idea behind the dam analogues is that by putting in some simple barriers that slow the creek and spread out the water, mimicking the work of beavers, the rodents will come in and take over.

Nader built about 25 of the dam analogues at Witcher Creek, and then the beavers built another 150 of their dams.

“I think our long-term solution isn’t grandiose projects, but simple stuff,” he said.

Let the rodent do the work. That’s what Joe says. You know Joe Wheaton who went to highschool in Napa and who’s sister came to the beaver festival twice?

The simple projects begin with beaver dam analogues, placing a few pieces of wood across a creek to slow and spread the water, then waiting as beavers move in.

Wheaton’s detailed, 288-page manual on Low-Tech Process-Based Restoration of Riverscapes is available free on the internet: lowtechpbr.restoration.usu.edu.

Oh be still my heart! Perfect timing. Perfect audience and perfect opportunity for beavers. I can’t wait to tell them all about it.

 


You will never guess what I got yesterday! The March 1 list of signups for the beaver summit. And guess how we’re doing now! 523  total. 306 from California and just a dozen shy of a hundred from CDFW.

Honestly I was so happy about CDFW I almost cried. And for an entire minute I was filled with a fondness for these hard working people who wanted to understand beavers better and who had signed up even though they weren’t getting credit from their employer or getting to leave work early.

25 states and four countries signed up too. Including NINE from Alabama. NINE!

Not a bad showing from the Pacific North West.  I’m thrilled to think that 523 people are going to understand beavers better. But mostly, mostly I’m just glad about CDFW.

Because they’re the ones I want to reach.

 

 

 

 

 


I am getting behind in beaver news stories. They have been piling up in my inbox. So let’s have a full smorgasbord today. Starting with Cedar Mill in Oregon.

Go Beavs!

This article pertains not to OSU sports teams, but instead to North America’s largest rodent, a common resident of Cedar Mill and Oregon’s state animal. The American beaver (Castor canadensis) was trapped almost to extinction across America by the 1800s, due largely to demand for beaver pelts. The undercoat of beaver fur is dense, and each hair is covered with tiny barbs that lock together – qualities that allow production of durable felt that can be formed into hats. Those top hats gentlemen doffed back in the day were made from beaver felt. However, after silk hats became fashionable in the 1840s, decreasing demand for beaver fur allowed these unique animals to make a remarkable come-back.

Beavers provide a variety of ecological benefits. Their ponds provide habitat for fish, amphibians, waterfowl, and songbirds. Beaver dams regulate water flow, decreasing downstream flooding in the winter and helping maintain higher streamflow in the summer. The ponds also improve water quality by trapping sediment. Beaver damage to trees may look intense, but many species they favor, like willows, are well-adapted to beavers and readily sprout back with multiple branches.

Perhaps in a future article, we can discuss the water fowl that make use of beaver ponds. Go Ducks!

That’s Oregon for you. Just a quick burst of beaver praised and then back to the game. Thanks for the shot in the arm before we head off to Ohio. Where we expect their reception might be much more muted, to say the least.

At least this beaver can enjoy the riverfront right now

A beaver that washed in with the flooding Ohio River has taken up residence in Smale Riverfront Park and seems happy to be there, according to Cincinnati Parks.

The little rodent arrived overnight, a Parks spokesperson wrote on Twitter. The Ohio Department of Natural Resources advised parks workers not to attempt to remove it — “it will find the way out on its own.”

Parks workers instead put a ramp near the beaver’s new digs in case it needs help climbing over the Smale railings and back into the Ohio River.

“For now, he’s just chillin’ and enjoying the sun and water,” a parks spokesperson wrote on Twitter. “We know he will find his way out soon.”

I can’t even imagine what happened to make you think a beaver ‘washed up’ on your shores. Beavers are VERY strong swimmers and rarely wind up anywhere they didn’t intend to go. But okay, keep an eye on him and let me know what you plan to do when he doesn’t magically go “on his way” again.

From Oregon to Ohio is a pretty big spread. Anymore O’s for beavers?

How about “Overseas”. This article strangely appealed.

The story of the rabbit, the wolf and the beaver megaphone

The story of the rabbit, wolf and beaver begins in the wild Iberia of the past, still untouched by human presence. In the past, the little rabbit was so abundant that it gave its name to the “Hispania” peninsula, the “land of rabbits”. Because it was so common, it supported great biodiversity, from foxes to owls, from the beautiful Iberian lynx to the majestic imperial eagle, and even vultures depended on the little rabbit. The wolf was the supreme predator that ran over mountains, plains and plateaus in forests, meadows and swamps. He hunted old, weak and sick animals: wild horses, mountain goats, deer, roe deer and wild boars. The beaver, an ecosystem engineer, shaped the streams and rivers from the shores of the Mediterranean to the Atlantic, passing through lakes and estuaries. Swampy areas were created that allowed for an abundance of amphibians, fish, and a wide variety of insects, and guaranteed that the water caused by the spring rains would outlast the peninsula’s hot and dry summers.

Today, in transformed Iberia, tamed by the present, the abundance of rabbits has given way to scarcity, the wolf is confined in small packs to northern Portugal and the beaver has disappeared from most of the peninsula and occupies only the Ebro catchment area. Both the decline in areas and the scarcity of these species have thrown the ecosystem out of balance. Today the rabbit is rare and an endangered species, it no longer plays its role as the basis of the ecosystem. The wolf has been reduced and its prey is either locally extinct (such as wild horses, mountain goats, roe deer, and deer) or a plague (wild boar). It is often dependent on pets for food and no longer plays its role. It is seen as a threat to animal husbandry and its role as a regulator of the ecosystem is being forgotten. The beaver, which was lost from Portuguese countries for a long time, is also remembered. Few know that it is an animal native to Portugal and Spain. Its absence has turned calm streams that ran year-round into wild waterways that only run for a few weeks or months.

I kind of like the idea that the rabbit was so abundant it gave the peninsula its name. And let me tell you we don’t often get articles mentioning both the Portuguese and Beaver. Just a side note, my mothers father was born in Suisun to a sheep farmer who immigrated from the Azore islands in Portugal. It never occurred to me that they might have once had beavers too.

When we learn to live in harmony with nature, when the focus is on caring and not on taming, when the basis is coexistence and not conflict, when the echo is more important than the ego, one can imagine a wilder Portugal . Where there are meadows with rabbits, lynxes and eagles. Where wolves hunt wild horses, deer, roe deer, mountain goats and wild boars. Where the beaver is free to turn the arid and arid landscape into wetlands flooded with life. There is an urgent need to restore nature. We need areas where animals can be free, where rivers can be rivers, where nature can be wild.

Amen. Here endeth the lesson.

 

 

 

 


It’s exacly  a month before the beaver summit! How did it ever get to be March 7th already? I wish I could have played list this weekend but Sonoma State didn’t send the updated version. All I know for certain is that we had some new State Park signups and that’s very good. More importantly, are you registered?

Yesterday I celebrated by playing with the audio of this NPR interview of Juli Scarmado, who was the student of Ellen Wohl and might have graduated by now. I wish every state had a couple Juli’s.

Meanwhile there’s beaver news from Idaho in a town call “Athol” which I would have a very hard time not teasing as the name of mean people with lisps for the same reason as kids used to make you say “My father works in a ship yard” while holding onto your tongue. Remember that?

Beaver problem at busy intersection in Athol

ATHOL — Beavers caused temporary calamity late Monday at South Athol Road’s intersection with Hapgood, Sanders and Tunnel streets, causing water to rise rapidly due to heavy downpours and disrupting traffic.

The Athol Police Department received more than one call in the early evening, reporting 2 feet of water had built up at the underpass area. One caller described water as being backed up and reported that vehicles were hydroplaning in that area.

Officers responded and assisted with traffic until the Department of Public Works arrived.

Assistant DPW Superintendent Richard Kilhart said the water backup caused by beavers “was the first time this year they have caused some difficulties.” The large, sharp-toothed rodents are building a dam in the drainage pipe and stream that run under the roadway.

Being that Athol is in the same state as Mike Callahan you would think that they have several people who know how to solve this problem with a beaver deceiver but maybe not.

Kilhart said the DPW made initial breaches in the dam to release the water, but could do little else until the department applied for a special permit to address the main problem. Once the breaches were made, the water level dropped.

“The normal trapping season is from Nov. 1 to April 1,” said Kilhart, “but this is a case where it is a threat to health and safety.”

The Board of Health approved the permit Wednesday to hire a licensed trapper to remove the beavers so the debris can be dismantled and the culvert cleaned out.

Sigh.
