Another savory dish Rob Rich sent my way was this essay by author Ginny Battson. It is a splendid, thoughtful and thought-provoking read perfectly designed for a sunday afternoon by the seaside or a cup of coffee and the first snow in your uncle’s cabin. Which means it deserves much broader thinking than I can summon, but the beaver parts are really, really good so I’m going to share them.

Beavers are Fluminists

I learn from rivers, as do the beavers. I spend time in and around them, observing and sensing. Two and a half thousand years ago, the ancient philosopher Heraclitus also wrote on the profound things he learned from rivers. In an age before science, he looked for guiding principles in nature. What he found in rivers was a permanence in a reality of apparent change. All is flux, a matrix of matter and movement. The river is an analogy for an elemental cosmos, yet materially effervescent. Rivers are also life systems ~ complex and dynamic.

Beavers, the river keepers, have evolved to be more than the sum of themselves. Beavers live in the life-flow, interrupt and send it in multiple directions. Known to ecologists as ‘keystone,’ First Nationers instead call them ‘sacred centres’ of the land. For they are whirling hubs of life-diffluence and life-confluence, integral to the flow just as mind cannot be separated from body. They are dam and bridge builders, storing water at times of plenty for times of drought. They sequester carbon by trapping it in fluvial muds that eventually become rich soils. They are coppicers; the trees they fell to feed upon and rear their young will regenerate, beaver-cuts catalysing a diversity of plant and animal life. They are also wildlife protectors ~ during winter, woody debris left trapped behind dams are buried beneath deep snow, and provide shelter for a host of smaller mammals and reptiles during the bitter cold. And then, when the northern hemisphere tips nearer to the Sun, melt water forms reservoirs and a rising water table, creating habitat for amphibians and a plethora of bird species, including waterfowl ~ wood duck and heron, migratory waders and passerines. New lentic deeps amongst woody debris provide fish fry safe passage to grow to adulthood. Majestic osprey take the adults. In lotic flows downstream, clouds of black fly larvae lay submerged, attached to substrate with silk, to emerge in spring and breed, then feed the bats that hunt on the wing above the beaver-cuts. The dams may eventually blow-out by flood, and the beavers will find new territory. Upstream, moose rear youngon regenerating meadow grasses years after dams are abandoned. This really is rich habitat; the smell of river, wood and beaver is intoxicating.

If beavers could speak human, they may also say: Into the same rivers we step and do not step, we are and are not.

(Heraclitus Homericus B49a)

Ginny introduces the word Fluminism to explain the interconnected dynamics of the universe flowing forwards, connecting and enriching and says it’s what beavers do best. She even goes so far as to call it a kind of love, or the doing and caring parts of loving. Her essay is filled with the richest imagery and most fluid prose. You should really tuck away the link and read it sometime when you have time to reflect. For now I will just say that she GETS beavers. I remember Skip Lisle similarly said the principal of beavers is dynamism, meaning change. They change things, things change them, the things that are changed by them change other things. Maybe after 10 years of watching beavers I can see how they changed me, how my life has rearranged itself because of their work.

Back to the Maine woods, and it’s getting late. I’m a little bit edgy because the light is falling. As I hurry back with my baby over the bridge towards Gilbert, we hear the slap of a scaly, flat tail hitting the water ~ splash. I stop and turn us around to follow the sound. My eyes adjust to the watery scene. And there is the beaver, Fluminist, swimming, with a wet, brown head visible for a moment and shiny eyes, before diving beneath the inky reflections of a darkening sky. She’s warning others we are here. Though we’d never harm her, others might. I feel at peace knowing she is here, knowing she has a rich intrinsically valuable life, full of love for this world in the river she understands so intimately. I point her out to my baby who instinctively feels both the joy and excitement. Formative moments, for sure. There is so much yet to learn from Ahmik, Fluminist, and I walk us home full of awe and gratitude.

Autumn watching Beavers

heidi08 Beavers, Beavers and climate change, Beavers and Forests, Beavers and Ice, Beavers elsewhere, Who's saving beavers now? October 28, 2017

You’ll be happy to know that the beavers in Hope Valley on the west fork of the carson river are doing just fine. We counted 7 dams yesterday in the cool clear flat water edged by leafless aspen and tamarack. It looks like nobody is messing with their idyllic lifestyle in the curvy shallows of the carson and we were happy about that! I’m sure they’re hard at work in these last warm autumn days to stock up that food cache for the winter. Good luck!

It is also very good news for us that one of our best beaver buddies in the UK is very tech savvy and made sure the complete autumn watch episode on the Cornish beavers was online and shareable. I’m not thanking them by name because the BBC frowns on this sort of thing! This is a rare treat so even if you never ever watch any video I post WATCH THIS! Trust me.

Wasn’t that amazing? They are being so smart about this, with the baseline study and the careful followup! Hurray for the farmer who had the sense to step into the forefront of this issue and allow his land to be reborn.

You never know where unexpected beaver friends will come from next. Here’s a fine defense of Heron pond from the Cabinet Press in New Hampshire! The author, Suzanne Fournier, is not at all happy with the actions of the conservation commission in charge.

Anti-conservation move must be opposed

The Milford Conservation Commission voted on Oct. 12 to lower Heron Pond by a foot! It’s quite an arbitrary decision, motivated not by what’s in the best interest of the pond and the threatened and endangered wildlife it sustains, but by vague expressions from the Public Works Director that the water is high enough already.

In summer 2014, Director Riendeau’s crew destructively lowered Heron Pond by four feet, absent a real emergency. The beavers eventually repaired the breached dam.

In fall 2014, along the Rail Trail, the CC had beaver pipes installed so low down that three ponds were drained of much of their water, one of them the lovely place called Dickerman’s Pond.

The CC members should be educating themselves more about the value and functions of a healthy wetland like Heron Pond that actually plays a major role in flood prevention.

They would also learn that drawing down Heron Pond with its Blanding’s and spotted turtles during the fall violates the directives in the N.H. Wildlife Action Plan that says turtles would likely die.

This anti-conservation move on the part of the CC must be opposed by all who care about wetlands and wildlife.

Nicely put! I honestly think this is a historic first for beaver reporting. Never before have I seen any paper or person complain about a flow device installed TOO LOW so that too much water drains away. Even in Martinez we didn’t complain about that because we were too grateful the pond and the beavers got to stay at all! Keep the pressure on, Suzanne. We think you’re doing ponds a great service!

Beavers: Past, Present and Future

Whew, I was relieved to hear that Mike Callahan (whose WIFE is a trapper) had never heard about using a cross-bow either to shoot unwanted beavers either. So that means this is just a one-off until we hear otherwise. (A horrible one-off but better than a common occurrence.)

Meanwhile, I received a note from author Ben Goldfarb yesterday that his writing retreat is going well and that he will have the first draft of his beaver book in November! How exciting! And I heard from Tom Rusert that their home didn’t burn down, their beloved bulldog Daisy is recovering from smoke inhalation, and things are moving forward. There was an excellent article in the East Bay Times and Fire Rescue about our good friend Luigi feeding the first responders last week, which surprises me not at all. That man has been incredibly community-oriented since before he even had a community.

Calif. deli owner feeds first responders in Calif. wildfires

MARTINEZ, Calif. —Luigi Daberdaku has been making sandwiches at his downtown deli for years, but never this many all at once.

Since Thursday, there’s been an assembly line set up in his shop, right near the shelves with the specialty sodas. “Cutting the meat, cheese, lettuce, onions, cucumbers, I need volunteers… plus I need more meat; we ran out of meat today after 275 sandwiches,” Daberdaku said Monday.

By that afternoon, as he prepared to make his fifth delivery trip, he and his assembled teams had made almost 1,500 sandwiches. It started Thursday, Oct. 12, when he and volunteers made 150 sandwiches by midday. He took them to Fairfield that first day for further distribution; since then, he has gone straight to the hard-hit areas, mostly in Napa, himself.

Dear, sweet Luigi, you deserve all the credit you get. I recall he had barely set up shop downtown at the November 2007 beaver meeting ten years ago, when he stood up with his very thick Albanian accent and said “When I first come to Martinez there was no one downtown. It was like a ghost town! And now that the beavers have come there are many, many people every day!” He has been our friend since the beginning, and his wonderful daughter Louisa planted trees, worked the festival and brought us sandwiches every year. Helping first responders is just the kind of thing he’d do.

(Let’s hope that sweet steady rain we got last night helped them too.)

Yesterday the National Geographic Blog called Cool Green Science decided that beavers deserve a little credit also. Of course they couldn’t resist reminiscing on Idaho throwing them from planes – but this is a pretty nice summary. Watch the video all the way through.

Restoring Beavers by Plane and Automobile

“Beavers are really nature’s engineers and they do a really good job at what they do,” says James Brower, Idaho Department of Fish and Game volunteer services coordinator. “We love beaver and we love what beaver do.”

“We really want them to set up shop and transform that habitat and make it a little better for everything,” Brower says. “Beaver create habitat for not only fish but also for deer, elk, moose and bear. Pretty much everything needs water and places to drink. There’s no doubt in my mind this benefits everybody.”

I like what Mr. Brower has to say. I think I will try and make contact. But I’m never a fan of the beaver-flinging story – as I’m sure you all know by now.

They made good progress on the fires yesterday (thank god), and were bracing themselves for the winds last night. The death toll has climbed to 36 this morning, with 5700 structures leveled. WP says 90,000 people are displaced and I bet the numbers are even higher. We’ll be coming to terms with the scale of these fires for many, many months and years to come.

In the mean time beavers have been the subject of attention by the National Wildlife Federation. I was contacted by the Vermont office rrequesting use of some photos for an upcoming event they are publicizing with Amy Chadwick in Montana about coexisting with beavers. (Which is just the right message delivered by just the right girl!) They thought Cheryl’s great photos would help promote it and Cheryl was kind enough to share. The announcement would link to this story in the August-September magazine which had escaped my attention entirely:

Beavers as Ecopartners

THE SUGAR CREEK RANCH FLY FISHING CLUB sits at the confluence of Sugar Creek and Scott River in northern California. The river’s cold water feeds the ranch’s eight ponds and lakes stocked full of fat trout and other fish that draw hordes of anglers. But the more important action is happening at the ranch’s unassuming beaver ponds. There, two beaver dams have helped save threatened coho salmon that were struggling to find enough water in the river just two years ago at the height of the state’s record drought. Today, the coho are thriving along with bear, fox, deer and hundreds of birds. “It is kind of a paradise,” says ranch manager Jerry Lewis.

The ranch’s beaver pond is one of many that the Scott River Watershed Council and its partners have encouraged property owners to create in the Scott River Valley to help restore water reserves while creating vital habitat for juvenile steelhead trout, coho and Chinook salmon. The trout and coho grow in the ponds’ still, cold water before swimming down to the ocean to fully mature and then return again several months later to spawn.

The ponds began with beaver dam analogues, or BDAs. Landowners can build these by pounding a series of vertical posts into a stream or river, interweaving branches through the posts then packing on vegetation and mud to create a dam that pools water. Enticed by the ponds, beavers often move in to build lodges and raise young and will increase the dam’s size and subsequent water retention.

To date, the Scott River Watershed Council has helped ranchers and farmers install eight BDAs in the watershed, and beavers have moved into six of their ponds. “Beavers have greatly enhanced the structures we’ve put in,” says Betsy Stapleton, the council’s board chair. “It has been a really cooperative relationship.”

Hurray for our Scotts River beaver friends!

A Beneficial Coexistence

“Farmers need to irrigate their land, but beavers can plug up a head gate where water comes off a stream in just 12 hours,” says Stapleton. “They can also dam up a creek near a home or field, which can flood them. And they chew down trees that people enjoy. When we started, we would barely mention the word ‘beaver’ in public. Then the drought hit. That really changed the conversation.”

California’s drought from 2011 to 2016 severely depleted water reserves across the state. When in 2014 segments of the Scott River dried up, the California Fish and Wildlife Department trucked thousands of juvenile coho to areas of the river that had adequate flows and habitat.

Since 2015, salmon and trout are thriving with the help of the new beaver ponds, which expand surface water, recharge groundwater reserves and improve water quality by filtering and trapping sediments and recycling nutrients. Their shaded, deep pools also provide cool refuge for fish and support a wide diversity of wildlife.

NOAA Fisheries biologist Michael Pollock is monitoring the region’s BDAs and found that they have raised water tables up to 3 feet as far as 1,500 feet from the dams. In addition, the BDAs have kept water flowing through fish-filled, downstream side channels all summer long, habitat that previously dried up during that time. Pollock says the positive impacts of the BDAs have reached far further than anticipated. “We didn’t expect that,” he says.

Federal and state agencies, including in California, are considering beavers as conservation partners to restore habitat and bolster its resilience to climate change. Not only do the dams build up water reserves but a series of dams can act as speed bumps to slow flooding, and they can even sequester carbon.

Several western states, including Washington, Oregon, Idaho and Colorado, are using BDAs or reintroducing beavers to help restore local ecosystems. For Montana’s Lolo National Forest, the National Wildlife Federation and its affiliate Montana Wildlife Federation are working with the Clark Fork Coalition to help the U.S. Forest Service craft a plan to build BDAs and restore beavers. This would help boost water reserves in riparian habitats at risk from reduced snowpack and increased droughts, which would restore habitat for threatened bull trout and other wildlife. “Beaver are low-cost workers, but they can provide huge benefits,” says Traci Sylte, the forest’s soil, water and fisheries program manager.

Hurray for beavers! It’s wonderful to read this rose-colored a collection of sentences like that but we all know that there is plenty of resistance still from the all kinds of agencies and property owners towards beavers. It’m always impressed with the work being done with BDA’s, and Michael Pollock is the very best kind of cheer leader to have on this team. In fact, I just got word that he’ll be opening the lecture series on tuesday evening at BioJams at the Olympic National Resource Center at the University of Washington.

ONRC Evening Talk: BIOJAMS Tuesday, Oct. 17, 7 p.m.

Dr. Pollock has been studying forest, stream and wetland ecosystems for over a decade. During this time he has engaged in a diverse set of scientific studies including: the influence of disturbance and productivity on biodiversity patterns in riparian corridors, the influence of beaver habitat on Coho smolt production and ecosystem function, the historical patterns of riparian forest conditions in the Pacific Northwest, and the importance of riparian forest to maintain stream habitat. Dr. Pollock will be speaking to us about his current research on the use of BIOJAMS — Working with beavers to restore salmon habitat.

How much do you wish you could be there? I’m just thrilled that all those students and professors will be inspired by the beaver gospel delivered by the very best teacher. We sent Michael a beaver tie after they were donated to us for the auction one year. I wrote him that this would be an excellent time to wear it.

Skipping to the rescue

Well, the wine country fires are nearly as deadly as the Oakland Hills fires now, and have taken more homes and plenty more acreage. The entire town of Calistoga was evacuated last night and the two massive sidewalls of fire around Napa are probably going to meet up today, which is terrible news for our friends and the Tulocay beavers. To top it all off Cal-fire just announced a red flag warning for much of the entire state, which means the whole thing will get worse before it gets better.

(I was vaguely remembering this morning how much people said they hated 2016, but they are going to remember it with fondness after this horrible year.)

The good news is that we heard from Rusty Cohn of Napa yesterday who is not missing but on vacation. We also heard from Susan Kirks of PLAN who said that Petaluma is terrified but holding steady. And our plucky little Martinez beavers have decided to forge ahead and rebuild one of the dams that were recently ripped out. Since there is fresh mud on the smallest dam, we can assume they must have repaired the larger too, even though we can’t see it. So we will take heart from their resilient spirits and fiddle on while Rome burns.

How one man tricked beavers and saved them — and roads — in the process

Knee-deep in muddy water, Skip Lisle wrestled with a metal fence, a key component of his invention, the Beaver Deceiver. On the morning of Sept. 29, deep in the woods of northeast Maine, Lisle pieced together the simple, durable device that he designed with one goal: trick the beavers, and in doing so, save the beavers.

Constructed on the upstream end of a road culvert, the device would prevent beavers from damming up the culvert and flooding the gravel road, something that is extremely common problem throughout the state.

“You hear about beavers being industrious and loving to work,” Lisle said. “That’s a myth. They’ll always choose the easiest damming site.”

Where humans see a gravel road with a culvert in it, beavers see a dirt dam with a tiny hole in it. As water rushes through the culvert, it calls to these natural builders, and their instinct is to “repair the dam,” block the culvert with sticks and mud so the area will flood, expanding their habitat. It’s what beavers do … unless you can somehow stop them.

That’s where the Beaver Deceiver comes in.

Maine is really a hotspot of beaver IQ at the moment. In the past two years I’ve covered stories as progressive as I’ve ever seen, and several that are equally backward – with hunting and trapping listed as the only solution. There is clearly some controversy going on there. But I’m hopeful with articles like these that beaver attitudes are moving in a good direction.

Growing up in rural Vermont in the 1970s, Lisle witnessed how beavers can rapidly change a landscape to benefit many other species of wildlife. On his family’s land, beavers constructed a dam across a waterway, creating a pond that expanded over the years, attracting a wide variety of animals to his backyard.

“There were so many animals using it, different species, and that stuck with me my whole life,” Lisle said.

When Lisle was bout 15 years old, the local beavers started damming up a culvert on a town road that ran through his family’s land. He realized that he needed to stop them or the road would soon be flooded. If someone else took action, the beavers would likely be killed. So he took charge and got creative.

“I actually stole some of my father’s old garden fence,” Lisle said, “and just built a crude fence in the culvert. And that’s when it all began.”

Constructing a fence around a culvert is the first step in building what Lisle would later call a Beaver Deceiver. But that invention was years in the making.

After receiving a bachelor’s degree in geography from Plymouth State University in New Hampshire, Lisle worked for ten years in construction, mainly doing painting and carpentry work. He then returned to school to earn a master’s degree in wildlife management from University of Maine in Orono. His thesis was on beavers, and more specifically, the wetland habitats they create.

“[Wildlife management] has always been my calling,” Lisle said. “I just didn’t answer it at first.”

Ahhh Skip! What a great article about a great man with a vision. Thanks for giving Maine such a lovely view of how and why to do this. And thanks for being our hero when we needed it. If folks need proof that it works, give us a call. Martinez was happy to function as a ‘test case’.

Now there are two more fantastic beaver stories on my waiting list I’m eager to get to. Assuming I’m not too stricken by fire-grief tomorrow to do my job, tune in for a great story of saving urban beavers in Port Moody BC.
