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

Month: July 2021


It seems like a million years ago now that I was invited to give a beaver talk at the SF waterboards in the Elihu Harris building in downtown Oakland. It was a huge and massive government hi-rise with a metal detector and lots of state employees hurrying about. I can’t even remember what the group was like but I remember they had been softened up by years of positive beaver news from Ann Riley, who was the reason I was invited.

It was probably the most official thing I ever did for beavers, and I was especially excited about it because the SF waterboards has influence over MARTINEZ of all places. And it was fun to imagine that I could influence their thinking about beavers for the future.

Well yesterday I randomly came across a Estuary scientist who retweeted my Op-Ed and talked about how important beavers are. Which was a nice surprise. I wrote to thank her for helping spread the word and noticed she hadn’t attended the Summit and I wanted to let her know it was available online.

Turns out Christina was AT THAT TALK! And thought it was wonderful and it really stayed with her. And she was thrilled to know about the recordings of the conference and wants to persuade more people about the good things beavers do. In fact she specifically asked what she can help do to get CDFW onto our side?

Her comments on my article were retweeted 92 times. At least. And must have touched a few hearts. It’s wonderful to think that that column is getting shared in more places and making an influence. And its wonderful to think that a talk made connections for people and stayed with them.

If I didn’t know better I’d think it’s almost like one crazy woman who loves beavers and talks about them over and over again CAN make a difference in this rotten mixed-up trap-happy world.


It’s amazing the lengths some cities will go to explain why they can’t learn to solve problems. It’s almost as if they think not learning excuses them in some way. Take Barrie for instance. It’s at the edge of lake Huron north of New York in Canada.

Busy beavers cause lots of dam problems in Barrie

About 30 times a year, one of Canada’s national animals becomes a pest in Barrie and needs removing.

Beavers like to down trees, move them around, build dams and block waterways – even in urban environments – and sometimes the only option is to trap them.

“The problem is city wide and occurs regularly from spring to fall,” said Dave Friary, the city’s operations director, of beavers. “The damage ranges from tree removal to the blocking of pond outlets, which results in a flooding risk to adjacent neighbourhoods and properties which expands to properties downstream of the pond.

Obviously not one account sits them down and says, wow you throw money at this problem every two weeks and it never goes away? Are you paying hushmoney or a hitman?

The cost to trap a beaver depends on the number of times the trapper must visit the site, Friary said, but the average is approximately $300, about 30 times annually in Barrie.

I’m sorry. Could you explain that again? So every trip out to kill some beavers makes you three hundred dollars and the more it fails the more money you make? Hmm. I think I’m seeing a problem with your incentive scheme here. Why not give ONE lump sum every year and the more they have to come out and earn it because they failed the first time is incentive not to fail?

Oh right. Your couzin Vinnie is the trapper you hire. And needs the ten grand every year. Sorry, I forgot.

Beavers in stormwater pond locations can also be relocated, but sometimes the city is unable to successfully relocate the beavers so they don’t return to the same spot, Friary said. And Ontario’s Fish and Wildlife Conservation Act only allows them to be moved as far as one kilometre away.

“The relocation of beavers is regulated under Ontario’s Fish and Wildlife Conservation Act,” said Jolanta Kowalski, who is with Ontario’s Ministry of Northern Development, Mines, Natural Resource and Forestry.

“It is not encouraged as an option because relocating the beaver to another area can move the problem elsewhere, can transmit disease among beaver colonies and can introduce a beaver into established beaver colonies which could result in the beaver’s death,” said Kowalski.

See if we transmit disease by moving the beaver he might die. Or if he gets attacked by another beaver in the area he might die. So it’s better if he dies for sure. You can understand that. right?

“Legally trapped beavers can be killed,” Kowalski said. “The Fish and Wildlife Conservation Act (FWCA) provides for the protection of beaver dams and makes it illegal to intentionally destroy them unless specifically exempted by the FWCA or authorized by our ministry.”

You can kill the beavers of course, but get your bloody hands off those dams. Those things can be damn useful!

And there are other options. The city has at times used small wire structures called ‘beaver bafflers’, which are placed around the outlet pipes in stormwater ponds – allowing the water to properly flow through the pond without causing flooding in the nearby neighbourhood, and does not disturb the beavers, Friary said.

But when beavers cannot be relocated so they can’t return, or the beaver baffler doesn’t solve flooding issues, a trapper is called.

Ahh so you admit there are alternatives but you have no idea what they’re for. Got it.

When this occurs the city has exhausted all actions and cannot properly protect public and private property from flooding and the city has the duty and authorization from the province through the Fish and Wildlife Conservation Act, to hire a trapper and manage the beavers accordingly,” Friary said.

“We contract the service out to a provincially approved trapper who uses a variety of methods of removal that can be found on the provincial website,” he said. “We indicate as part of the contract that methods used need to be humane and within provincial guidelines. Each circumstance may be unique and up to the trapper.”

Exhausted all actions? You mean to tell me that 30 times a year the city exhausts all actions. installs a baffle, wrings it hands and has to call Vinnie to trap again. You are freakin kidding me. The city doesn’t EXHAUST all its options every decade, let alone every other week. You barely wash your hands every other week.

“The killing of beaver often causes a great deal of controversy within the city that’s really difficult for people to deal with,” she said.

I really, really believe that.

She said most municipalities, when they have a beaver issue, call the Ministry of Natural Resources, which provides phone numbers for a number of trappers, and the trapper removes the beaver.

“And that sounds like a pretty easy way to deal with the situation, but the fact of the matter is when you look at the situation in total, the cost of doing that plus removing the dams and blockage of drainage ditches and all sorts of different areas where beavers might cause conflict, the cost to the city is significantly greater than dealing with things like beaver bafflers, different types of flow devices, including in stormwater management ponds, that allows the beaver to stay, that allows the municipality to deal with the diversity that the beaver brings, while preventing flooding,” White said.

Wait just a dog-gone minute here, this article is starting to make sense. Better end it RIGHT NOW. Don’t start telling me that the 10 grand they pay to kill beavers every year is just PART of the cost. If you keep explaining how this works people will start learning, and you don’t want that do you?

I didn’t think so.


There’s a new beaver mural in San Luis Obisbo thanks to the hardworking beaver brigade and inspiring artist Victoria Carranza. Victoria uses community engagement to bring murals to life. She is especially interested in highlighting local nature, so you know this beaver wetland was a natural choice. Members of the brigade and their children and families came and did the painting, prepping the surface priming and working at night when it got too hot.


I’m not sure the beaver is CENTRAL enough for my tastes but it’s a beautiful tribute nonetheless. Audrey Taub has done a fantastic job of engaging her community and really getting beavers the attention they deserve. Cooper Lienhart explains things very welll in this is a nice film made by an appreciative pilgrim to the site. He does a good job profiling the word the Beaver Brigade is d[wonderplugin_video iframe=”https://vimeo.com/575017115″ lightbox=0 lightboxsize=1 lightboxwidth=960 lightboxheight=540 autoopen=0 autoopendelay=0 autoclose=0 lightboxtitle=”” lightboxgroup=”” lightboxshownavigation=0 showimage=”” lightboxoptions=”” videowidth=600 videoheight=400 keepaspectratio=1 autoplay=0 loop=0 videocss=”position:relative;display:block;background-color:#000;overflow:hidden;max-width:100%;margin:0 auto;” playbutton=”https://www.martinezbeavers.org/wordpress/wp-content/plugins/wonderplugin-video-embed/engine/playvideo-64-64-0.png”]oing and why it matters.


More and more often these days I am approached by a starry eyed beaver believer with impatient exuberance saying “WELL the tide is turning isn’t it? That’s the beginning of the end for stupid beaver arguments:” and  I slowly shake my head like the wizened believer I am and say, hmm not yet young grasshopper, Not yet. And the newly converted get SO frustrated with me as if my hesitance makes the world slower too. But there’s a dam good reason for my skepticism. I’ve been hurt soooo many times before.

Thankfully this fine column was printed in Virginia today  confirming skillfully that it ain’t over till it’s over.]

Commentary:Considering the beaver…


One of the waterways on our property is a perennial stream with a 3-acre pond and an island. Over the years, beavers have come and gone with minimal activity. Once their habitat was protected, they became more active and more destructive — and there were more of them.

Over time, they clogged the outflow pipe from the pond and barricaded the spillway, causing water to run over and erode the dam. They have flooded mature trees and cut down others planted as part of the CREP program. Most heartbreaking, they have destroyed the dogwood and flowering cherry trees planted on the island.

Ohh pulleeze. And there were more of them? Just how exactly did you count them sir?   And did you also count the number of trees that flourished or coppiced because of the added water in the pond? Of course not, I know.

Recently, in an article in the Rappahannock News [“Coexisting with castor canadensis,” May 13, 2021], it was reported that the Virginia Department of Transportation estimated beaver damage in 2008 cost an average of $29,000 per incident.

On the other hand, in the same article, Rappahannock resident Bill Fletcher was reported as seeing benefits of beaver activity returning to his property this year, including re-emerging springs. It was also reported he would like to see a government-funded program to pay to build manmade beaver dams that would attract beavers on the streams of Virginia farms. 

I believe this is the part where you say “My mind’s made up. Don’t try to confuse me with the facts!.”

I know Bill Fletcher has good intentions, so I make this offer: He can take as many beavers as he wants from our farm, free of charge. It is a violation of the law in Virginia to relocate beavers, but trust me, I’ll never tell.

See what he did there? He made a funny at the beaver’s expense and he demonstrated that every one worth two cents knows that farmers will accept ecological funding directed at saving water or preserving habitat and continue to do exactly what they have always done because they know best.  Sometimes it will be a well kept secret and sometimes every body knows,

 


Every so often I google search for “beaver dam complex” just to see if there are any new remarkable images worth sharing. This one is still wowing me. From USGS it is described as “Beaver dam complex and lodge at the confluence of Wrench Creek and Kelly River, Noatak National Preserve”.  In Alaska of  course.

What a fantastic place to be a beaver!se
