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.

Saved by the beaver

heidi08 Beaver Chewing, Beavers or Social Ambasadors, Educational, Environmental, Friends of Martinez Beavers, Urban beavers, Who's saving beavers now? October 13, 2017

Yesterday and last night were not as bad as they feared. There was even a FB update from Safari West at 8:30 pm saying they spent the day feeding the animals and shoring up defenses. I can’t imagine how they’re survived because on the Cal-fire map there is just a huge red cloud from Healsburg to Santa Rosa. But somehow they persisted. The parts of Napa that were expecting to be told to evacuate didn’t have to because the fire turned a little. Which means our Tulocay beavers are okay. I read a story this morning about a 70 year old couple from Santa Rosa that survived by submerging for 6 hours in their neighbor’s pool while everything burned around them – hiding like beavers below the water until they needed to breathe. They made it through the night and are miraculously not among the 31 dead.

Speaking of beavers and resilience I wanted to share the wonderful letter I received Monday from Judy in Port Moody BC. .

Hello from Canada

I am writing from Port Moody, British Columbia, and I have been following your website for years. I am a member, and former board member, of The Fur Bearer Defenders. Last year two beavers moved into a creek just a few minutes from our home and I have been dedicated to making sure this family survives.

Pigeon Creek is a small stream located in the middle of the Klahanie development on Murray Street, Port Moody. The creek is part of a green easement that runs between two low rise condominiums. The population of Klahanie is about 2000.

The creek was originally landscaped by Polygon development but has slowly been overgrown by several invasive species including Japanese knotweed, Himalayan blackberry and some smaller plants such as bittersweet nightshade. However there is still a preponderance of Dogwood, Willow, Aspen and a large stand of mature Cottonwood trees.

In November, 2016, my husband, Jim, and I discovered the start of a small beaver dam. We are familiar with the activities of beavers because Jim has volunteered to help Adrian Nelson, the wildlife conflict specialist with The Fur Bearers, install beaver flow devices throughout the lower mainland and up along the Sunshine Coast to help mitigate the effects of flooding from beaver activities.

You can imagine how hooked and fascinated I was at this point. A knowledgeable beaver advocate in the making! With a husband who helped Adrian install flow devices! And who had followed our website for years! Be still my heart.

We soon spotted what appeared to be two juvenile beavers working to dam a portion of the creek. The work continued throughout the winter and the two beavers seemed to become more comfortable in their new environment and were seen by the residents on a more regular basis.

By April we were only seeing one beaver and assumed, rightly as it turned out, that the female may have been pregnant. During gestation the male built a separate bank den.

During this time I was approached by the new General Manager for the Environment with the city of Port Moody, who told me she wanted to relocate the beavers. I knew that the province of British Columbia was not issuing relocation permits and that her intention was to trap and kill the beavers. Adrian Nelson, Jim and I met with her and convinced her to take a different approach and manage the beavers “in place”.

Although we have an understanding with this General Manager, I am cautious and am taking every step to ensure that these beavers remain undisturbed. It has been very stressful for me because she has given me misinformation about the beavers that has led me to believe she is not knowledgeable about them.

Oh, yes the old “We want to relocate these beavers” trick. If we’ve heard it once we’ve heard it a thousand times. ‘You’re puppy went to live on the farm’. It’s a fairly common ploy (or maybe not a ploy). Maybe folks really think it’s possible until they start making the phone calls and then they just let the story cover their tracks.

We finally got the first glimpse of the two new kits, late in the summer, when they were about 8 weeks old, now weaned and starting to eat leaves.

What I find so remarkable about this entire storyline is how the residents of Klahanie have responded to this new family in their midst. We have a community face book page here, for residents only, and people are constantly posting pictures, videos, drawings and even hosting contests to name the beavers. The male is named “Brewster” and the two kits are called “Woody” and “Chip”.

Jim and I have been wrapping trees to protect them from beaver damage, tracking what they are eating and I am providing educational posts on the face book page. I have invited a local biologist to give an evening Wildlife Talk and we had a good turn out for that event.

I would never have guessed, when we first spotted the beaver dam, that this pair of beavers would turn out to be such an attraction in our community. Every day there are people who come to watch for the beavers and the easy viewing location and accessibility provides everyone with a window into the lives of these animals. Beavers are not common in Port Moody and this is the first one in the city for almost a decade. Our viewing area is similar to yours, a pedestrian walkway on the bridge over the creek.

My very favorite parts are in bold because I just LOVE the idea of beavers enlivening and educating the community and attracting attention. Just like they did in Martinez. Urban wildlife helps neighbors talk to each other. Especially beavers. It’s as simple as that.

I am including a link to a new you tube video that a resident of Port Moody just made about our beavers.

Turn your sound up for this, the train reminds me so much of Martinez!

Judy! We are so impressed by your letter and heartfelt interest in these beavers. We love the video. We think those beavers are enormously lucky to have you and your husband in their corner. Communities that watch beavers are the best kind of protection against over-eager general managers. I wrote her yesterday with lots of ideas and this website has a host of resources for folks wanting to keep beavers safe and energize the public. I also suggested she might want to sign up for the webinar I’ll be giving this month about how Martinez saved our beavers, and I’ll say more about that later.

Thanks Judy for writing and telling us this fantastic story.

Lovely but slow yesterday at Wild Birds Unlimited. Plenty of folks were dam interested to find out there were beavers living just one block up! We left the sign with Mike so he could continue to pass on the word. There were lots of interesting people and conversations but my favorite has to be the man who said he lived on a lake one summer in Illinois and would canoe every day. Whenever he’d show up a beaver would surface along side him and swim beside him as long as he paddled slowly around. He said it happened nearly every day in the month he stayed there, and showed it was an adult beaver in describing its four foot length. Isn’t that a wonderful and rare story?

It made me think of Grey Owl and this striking video.

When I got home Bill Leikam sent me this from a buddy doing sound recording in the Catskills at a beaver pond. What you are hearing is coy-wolfs, geese and a flying squirrel chittering. If you feel any stress at all after listening to this, I’d be very surprised. Enjoy.

I’ve been hearing a lot of talk about this new text book, which was slated for release in August of this year. Dr. Carol Johnston is the professor from South Dakota who recently used those historic maps from Morgan to show that beavers build in the same areas for 150 years. The book looks very interesting. Minnesota Ag just reviewed their copy but where is mine?

Beavers Shape Northern Minnesota Ecosystem.

Beavers have probably been more influential than humans in altering the Kabetogama Peninsula ecosystem in northern Minnesota, writes South Dakota State University Professor Carol Johnston. She examined how beavers have impacted the peninsula which is home to Voyageurs National Park near International Falls, Minn., in her newly released book, “Beavers: Boreal Ecosystem Engineers.”

“This book is about a place and the science of how beavers shaped it,” said Johnston, who has been conducting research on beavers for 30 years. She wrote eight of the book’s 10 chapters based on her National Science Foundation-funded beaver research.

The text book is listed as a pricey 137.00 at Amazon, but shows the following drool-worthy pages of contents. It takes a second to load but trust me it’s worth it. There isn’t a single chapter I’m not eager to read. It’s maddening to think of all the text books I shelled out major cash for and never really read more than I needed to, (or frankly, even that) and this one that is sooo delightful-looking now that I’m not a student!
