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

Category: Who’s saving beavers now?


Today is the day I’m letting you know that it’s time to sign up for your Compassionate Conservation webinars with Fur-Bearer Defenders. They’re free, easily attended from your computer and packed full of useful information. It is truly remarkable that FBD makes these webinars available world wide. They cover truly relevant topics like predators, presenter language and avoiding compassion fatigue, And oh, will you look at that! One of them will be about beavers and taught by yours truly!

Pragmatic Compassion: Teaching Martinez that Beavers were ‘Worth A Dam’

In 2007, Martinez California USA was surprised to find beavers living in the city creek. Officials were worried their dam would cause flooding and recommended trapping. Heidi Perryman worked to convince the city to install a flow device instead and started the beaver advocacy group Worth A Dam. Now she teaches other cities how and why to co-exist with the important ecosystem engineer.

Heidi is a child psychologist who became an accidental beaver advocate when a family of beavers moved into the creek near her home. Now she lectures about beavers nationwide and maintains the website martinezbeavers.org/wordpress which provides resources to make this work easier for others to do.

Okay, I’ll be the first to admit it’s not exactly a catchy title, but I really wanted to work the word “PRAGMATIC” into all that compassion, so it’s what we ended up with. Even though I’ve talked about our beavers a thousand times before this is different because a) I can’t use video and b) I want to emphasize the advocate’s role in saving wildlife. So it’s been an interesting challenge putting it together and re-including all the behind the scene things I usually leave out of my talk.

It would be SO nice to see familiar faces there, so sign up if you can, (assuming the formidable technology involved works and it actually happens) next tuesday at 1 pm!

More surprises? It turns out an Oregon Fish and Wildlife refuge is eagerly awaiting beavers too!

Tualatin River National Wildlife Refuge marks 25 with fanfare

Skeins of Canada geese overhead may be a common autumn sight at the Tualatin River National Wildlife Refuge, but it felt nothing less than extraordinary on Saturday, Oct. 14, as the community gathered to celebrate the refuge’s 25-year anniversary.

In the Riparian Room of the refuge’s visitor center, refuge staff, volunteers, Friends of the Refuge members and visitors gathered to share the story of the refuge’s beginnings and its goals for the future.

As part of the anniversary celebration, visitors were invited to meander through the wetland along the site of the refuge’s next big project. Starting next summer and finishing in 2019, the refuge will restore Chicken Creek, which currently flows in a straight path to the Tualatin River through an agricultural ditch, to its historic channel through the floodplain. By replanting trees and shrubs along the bank, the refuge hopes to attract American beaver, an animal architect that will in turn enrich the area for many other species.

What do you know? Planting trees to encourage beavers at a refuge, while here in Northern California at the Malhleur refuge in the delta we know they’re actively killing them. Sheesh. Baby steps, right? Let’s all appreciate wisdom when we see it. Thanks Oregon!


1They 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.


RZAD7WN7JI3W7PY4JS7RUGZ2UAYesterday 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.

urban beavers


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.)

DSC_7858The 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.

CaptureConstructed 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.

truck“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.


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!
