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

Category: Beavers and water


CaptureNot too long ago Rachel Hofman of the NWF magazine in Vermont contacted me about an event they were co-sponsoring with the Clark Fork Coalition in Montana about the benefits of beavers. She was working on a flyer to promote the event and wanted to use a few of Cheryl’s great photos to do so. The talk would be given on October 25th by Amy Chadwick, who is also a friend of ours.

It sounded like a fine cause, and it reminded me I hadn’t seen that particular photo in a while, so Cheryl gave consent and then we pretty much forgot about it because not long after our exchange the entire napa-sonoma valley erupted in flames and that held our attention for a while. Yesterday I was reminded of it by reader Rob Rich who sent me some great information they put out on beavers. It reminded me that I had forgotten to share it, so enjoy!

Beavers – Nuisances or Watershed Heroes?

For CFC’s inaugural Beaver Month we chatted with Andrew Jakes, Regional Wildlife Biologist for National Wildlife Federation about the unsung bucktooth heroes of the watershed – the beaver.

Why are beavers considered ecosystem engineers?

Beavers aren’t just considered ecosystem engineers…beavers are THE quintessential ecosystem engineer! They change a landscape like no other species in the world, besides humans. They change the landscape to suit their needs, and when they do that, it turns out that they change a lot of other things too.

OK, so what else changes in the landscape when beavers are present and building dams?

So much! When beavers show up, a lot starts to change. Studies have shown that beaver dams change everything in the system; from soil to vegetation to water quality to wildlife. It’s hard to sum up in only a few sentences, but I’ll do my best to give you a summary…

First of all, beaver dams slow the flow of water. This means water is on the landscape for longer. This can cause the floodplain to expand, soil structure to change, and the water table to rise. All of this also means that riparian vegetation can thrive. This means extra foraging opportunities for beavers and other creatures, so more wildlife starts to frequent the area. It’s no secret that wetlands are beneficial to the ecosystem, and beavers are little wetland creators.

The bottom line of all this is that when a beaver dam shows up, we see an increase in biodiversity, which thereby means the ecosystem becomes more resilient.

You can read the rest of it the fine story here.  The entire ‘beaver appreciation month’ concluded with the talk by Amy Chadwick at a local pub in Missoula on Thursday evening. Obviously convincing the land owners of Montana to coexist with beavers takes the best and the brightest, and Amy (who worked with Skip Lisle) is well up to the task.

Walk and Talk: Busting Beaver Myths

During the month of October, the Clark Fork Coalition is putting a spotlight on the hard-working, fur-ball hero of the watershed – the beaver.  Join the Clark Fork Coalition and Ecologist Amy Chadwick for an evening of natural history and cutting-edge restoration featuring beavers and beaver mimicry. Chadwick is an Ecologist at Great West Engineering and the chair of the Montana Beaver Workgroup. Amy has been working in stream and wetland ecosystem assessment and restoration in Montana for 20 years, but in recent years her work has focused primarily on beaver habitat restoration and improving natural water storage.

Amy will share facts of about beaver ecology, review how beaver act as ‘ecosystem engineers’ in western watersheds, and share the implications lost beaver habitats on our water budget.  Chadwick will be joined by Andrew Jakes, Wildlife Biologist with the National Wildlife Federation for a discussion of beaver habitat recovery work underway in the Upper Clark Fork and a Q & A session.

Don’t you wish you were there listening to Amy’s talk? I met her at the Beaver Conference in 2013 and we have kept in touch over the years when beaver issues arose over the years. She worked with Skip installing flow devices in the area for a while and now carries on the work bravely on her own. It’s wonderful to see folks like Amy and the Clark Fork Coalition working in their own backyard to make way for beavers and teaching others about their benefit to the environment. I hope the beaver night was a resounding success and I hope NWF thinks of us first when they have a beaver event to promote in the future!


There’s a nice story this morning about watching beaver activity as we head towards winter from Marshall Helmberger of Minnesota.

The busy season

It’s the busy season at our neighborhood beaver pond, as the locals prepare for the impending season of scarcity. The signs of activity are everywhere, particularly along the pond’s edges, where the resident beavers have recently felled at least a couple dozen youngish aspen to put away for the winter.

It all seems pretty familiar. We fill our own wood sheds and stock the pantry and freezer with the season’s produce, and the beavers do pretty much the same. This time of year, the beavers are cutting aspen and willow and storing the branches and smaller trunks in a huge cache under the water, just outside one of their two lodges. These caches are readily visible this time of year— since some of the smaller limbs often stick out from the water— and are an easy way to tell if beavers are planning to spend the winter in any given lodge. Beaver lodges can last for decades and they can fall in and out of use over the years, so this time of year I always look for the telltale signs of a fully-stocked pantry to determine if a lodge is currently active.

Once the ice arrives on the beaver pond, which could happen this coming week given our recent cool down, the beavers will be locked in for the winter. They’ll live the next several months within their dark lodge, only occasionally venturing out of one of their underwater exits to grab a bite. While their pantry of sticks is their primary source of winter food, they also store large amounts of fat in their tails this time of year, which they will also rely on during the winter months. A beaver’s tail, in the fall, is usually substantially larger that it will be when the beavers emerge from their lodges next April or May.

Don’t you wonder what that’s like? Or which family member you like enough to be stuck in a closet with for three months out of the year? I’ve been fairly lucky in terms of opportunities to see beavers, but I will always regret not getting to see this. The tell tale food stash and the signs of beavers cracking through the ice to get whatever they can forage. I’m not entirely sure I believe the last sentence about their tails being smaller in May, but I bet our beaver size has a lot to do with not needing to live off reserves. Marshall does a nice job in this piece by capturing the urgency of late fall.

Speaking of beaver authors, I heard from author Ben Goldfarb that he just had a very enlightening chat with our city council man Mark Ross about the beaver story. He said it was helpful to get the city perspective on the story.  (I would just LOVE to be a fly on the wall for that conversation, wouldn’t you?) I bet there were lots of fears of flooding and very few honest concern about voters in his tale.

Meanwhile it you want to get the story from the other perspective, why not listen to the talk I did Tuesday from the convenience of your desktop. I really appreciate fur-bearer defenders for getting this online and sending me the link! This will give the whole story plus some never before disclosed secrets from behind the scenes. (You can thank them for doing tall his by dropping 5$ in their donation jar.) I just realized that the anniversary of that big November meeting is a week after halloween! Perfect timing to hear it all again or for the first time. I think my voices sounds lower, what do you think?


There were two news stories yesterday that touched on the history of this blog. One of them was positive so we’ll do that last. The other is less positive but I’m at least happy that the reporter wrote me back this morning and apologized for not asking US first. Ahem.

What’s up with all the wayward beavers?

WALNUT CREEK — An injured beaver discovered recently in a Pittsburg parking lot near Kirker Creek may have lost its sight, according to the Lindsay Wildlife Experience.

When the Contra Costa County Animal Services Department brought the 35-pound male beaver to the Lindsay on Oct. 18, the animal was lethargic and staff believed he may have suffered head trauma and an injured jaw.

The medical team had been monitoring the beaver’s condition, administering pain medication and treating him with antibiotics for minor injuries.

Two days after the beaver arrived at the Walnut Creek hospital, however, Lindsay staff discovered that the animal could not see, which may be a temporary side effect of the head injury, said Elisabeth Nardi, associate director of marketing.

If the beaver is permanently blind, he would not be able to survive in the wild, she added.

Poor guy.

Typically, the Lindsay receives only one or two of the large rodents per year, but this is the fifth the nonprofit has cared for in 2017. Wildlife experts are not sure why so many beavers are venturing from their lodges into areas with people.

One theory is that the beaver population has grown.

The heavy rains that soaked the Bay Area last winter produced lush vegetation for the toothy animals to eat, so more kits may be surviving.

A second hypothesis is that people are encroaching on the animals’ habitat.

“We have had the better part of 10 years of drought and the human population in the Bay Area has increased and spread out more during that time,” said Amber Engle, Lindsay Wildlife Rehabilitation Manager.

First of all, stop spouting theories about the population growing and ask the REAL BEAVER EXPERTS at Worth A Dam. Sheesh.

I actually heard about this poor little guy thursday morning from Cheryl, who was alerted by their vet. But this particular unconsulted beaver EXPERT doesn’t think it has anything to do with the population growing. (!) This wet winter and spring was terribly hard on beaver families. Flooding dislocated them all over, not just in the Bay Area. A beaver that is suddenly without family or home is disoriented and confused. He or she can easily wander into a public area, get hit by a car, and wind up in rehab.

This beaver’s dislocation is NOT storm related. And he sounds sick. The blindness makes me think of our very first sick kit. Remember that? He was picked up swimming in circles and they discovered at Lindsay he was blind.

After he died a necropsy showed that he had brain damage caused by round worm parasite that was responsible for his blindness.

And for goodness sake don’t euthanize a beaver just because he’s blind. Put him some farmer’s pond or backyard and let him find his way. Beavers have routines,their eyesight isn’t good anyway, and it he had a reliable food source he’d be fine  and figure things out on his own. Two thirds of beaver life is probably spent sightless anyway – underground or underwater.

Go here to donate and remind Lindsay that caring for sick beavers is Worth A Dam.


 

Better news comes from Southern California at the site of the big bruhaha nearly two decades ago. For newer readers Lake Skinner was a reservoir that made a decision to trap out beavers and caused resident outcry. When they were challenged on this decision they said that the beavers were  threatening the homes of endangered birds in the area, the least Bell’s vireo and Willow Flycatcher and had to be killed to protect them.

The outraged citizens hired an attorney who brought the whole thing to court, filing suit against the metrolitan water district, the power company and CDFG. When they lost they brought the matter to appeals court with expert testimony by the likes of Sherri Tippie and Donald Hey.

This time they won because the smart attorney (Mitch Wagoner) argued that that removing the beavers was a violation of CEQA and the court agreed that the decision was “discretionary” and not “ministerial” (meaning they did it because they wanted to not because they had to.) So they lost big time and had to all those pay court costs.

In addition but seperartely, researchers in the area were attracted to the story and published an article about the whole stupid decision wonderfully called “Management by Assertion” which remains one of my favorites.

Well yesterday this was posted including some of their findings.

Skinner Reservoir – Lake Skinner Temecula Ca

The reservoir and nearby Southwestern Riverside County Multi-Species Reserve host endangered species such as Least Bell’s vireo (Vireo bellii pusillis) and Southwestern Willow flycatcher (Empidonax traillii extimus), dependent on riparian willow habitat that is created and maintained by North American beaver (Castor canadensis).

Now originally I thought this was on the reservoir website which would have been awesome, but today I can see it was just a blog that I think might be computer generated. Never mind. It is still very good news though because the it means that the information from the good guys in this lawsuit and study is so widespread that it’s easier to pick up than all the lies they wanted people to believe and had a staff of thousands to spread.

Beaver truth will out. So there.

 


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 Capture

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.


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!
