SCOTTISH FARMERS THINK KILLING IS WORKING SPLENDIDLY

heidi08 Beavers and water June 5, 2020

New photo from Roland this morning, I would recognize this as Napa from a million miles away. Look at all that duckweed surrounding that adorable little face,

Roland Dumas: kit with tail up

Keep looking back at that photo as you read this fairly upsetting article from the Scottish Farmer noting that there has been ‘JUST ENOUGH KILLING’ to keep everything ship shape.

Beaver management proving fit for purpose

Scottish Natural Heritage has released a new report revealing its beaver licensing statistics – in the eight months following the species being given formal protection on May 1, 2019, the agency issued 45 licences which permitted either lethal control or dam removal.

Licenses were granted when there was no other effective solution to prevent serious agricultural damage. Five of the licences permitted dam removal or manipulation only. All licences were issued for the purpose of preventing serious damage to agriculture and all but one of these (97.5%) were issued on land classified by Scottish Government as prime agricultural land, which makes up 13% of Scotland’s land cover. Evidence of serious damage included waterlogged fields and crops, as well as erosion on riverbanks and embankments.

Under these licences, 15 beavers were trapped and moved to either Knapdale or a trial reintroduction project and fenced sites in England, 83 beaver dams were removed, and 87 beavers were shot by trained and accredited controllers.

Licenses were granted when there was no other effective solution to prevent serious agricultural damage.

Mind you, I’m not Scotish, but I think I have a VERY VERY GOOD idea of exactly what kind of exhaustive nonlethal measures were tried to prevent damage. I’m going to guess it involved ripping out the dam, and when the beavers built it back, well then lethal means were needed.

GRR.

Under these licences, 15 beavers were trapped and moved to either Knapdale or a trial reintroduction project and fenced sites in England, 83 beaver dams were removed, and 87 beavers were shot by trained and accredited controllers.

So basically like a quarter of the population? That’s all? Who knew that beaver killing would be a side effect of Brexit. Well, besides us that is.

“It’s always been clear to both us and our partners that lethal control of beavers will sometimes be necessary under licence as a last resort when other mitigation is unlikely to be effective,” said SNH director of sustainable growth, Robbie Kernahan. “Some of the well documented and most serious issues have occurred on the most productive areas of agricultural land in Scotland. Due to their generally being well-drained, low-lying and flat, these areas are often vulnerable to beaver burrowing and dam building,” he explained.

I want a list. I want a list with photographs explaining each issue caused and the brilliant steps taken to resolve it before beavers were killed. You have one, right?

Welcoming the report, NFU Scotland president Andrew McCornick said: “In its first year of operation, the accreditation, management and licensing framework for managing beavers…is proving effective and fit for purpose.

“It has allowed the management of beavers in those areas of productive farmland where the species has had a clear impact,” he continued. “The report notes that more than 90% of beaver territories have been unaffected by the licensing system.

We were might suspicious at the onset, but after careful consideration and examination the killing appears to work just fine. What a relief. Will someone much wiser than me please explain the ridiculous final paragraph?

“While that may involve lethal control, we note from the report that three-quarters of licence holders have proactively engaged with the role of trapping. NFUS is encouraged to see that where mitigation was proven to have worked, there was no longer a need for licensing.” he concluded.

I’m pretty sure it means farmers are so good at killing beavers they should just be allowed to get on with it themselves? You know like in Oregon where any private landowner can kill any beaver on his land without interference.

Please ask the farmers union if they would still like the water?

 

SLO NEWS DAY FOR BEAVERS

heidi08 Beaver ecological impact, Beavers and saltwater June 4, 2020

I’ve been gloating for a couple days. Time to be crumpled with envy again as we watch other beaver advocates enjoy the sweet success of their efforts for which we can never hope. This time it’s from our friends in San Luis Obispo who recently had a very special visitor. Dr. Emily Fairfax came for a beaver visit and brought her favorite equipment with her.

What a treat, I got to show our beaver dam to Dr. Emily Fairfax, Assistant Professor, California State University Channel Islands, Environmental Science and Resource Management. She was the researcher that studied large-scale wildfires and beaver habitat and made a great stop-motion video demonstrating her findings.

It was so fun to walk around the beaver dams and beaver lodges and learn so much about an area that I visit regularly. First, she called our beaver dam a “Jewel” of a beaver complex. She pointed out all the ways the beavers have committed themselves to this area, the 7-foot deep moat around their bank den, the beaver lodge (ie. second story) they were adding on to the beaver den (that I never even noticed before), the series of micro-dams on the hidden back side of the den that were widening the river and creating a safe hidden path to food sources.

As we walked in the water, we would occasionally pass through really cold patches of shallow water, she said these were places where the ground water was coming up, cooling the water and recycling the river water back into the ground (something like that), keeping the river water at that perfect fish-loving temperatures. She took a thermal image of the water and the dams also, which are sooooo cool.

Oh I remember having ‘experts’ come to the beaver dam. And how we would hang on their every word and ply them with endless questions. Experts from out of state or across the country. We learned so much from them. In retrospect though from years of experience I can say that nobody really knew our beavers better than we did. No matter how much they knew about beavers.

And the best part!?!?!?! She wants to do a study of this beaver complex, watching, recording, capturing photos, as the seasons change, gathering data within the beaver complex and comparing to data outside of the beaver complex. Is that the most exciting news ever or what!? I can’t even believe it.

That is VERY exciting. For you. I sooo wish that had happened for us. Sniff. I whimpered to Emily and she said gamely “I can still come and study your beavers!” But I sobbed

Dr. Emily Fairfax

“No you can’t because we don’t HAVE any beavers. Waaaaaaaaaaaaaaaaaaaaaaaa”

But still. Still. It’s GREAT news for our friends in SLO and great news for beavers in general. I’m so glad Emily is on the job! You MUST go to the website to see the AWESOME 360 image of the beaver habitat. I can’t embed it here but it’s amazing!!! Those are some happy beavers munching on all those cat tails.

Oh and speaking of great news, Robin of Napa had an excellent sighting at Pearl Street.

ZOOMING FOR BEAVERS

heidi08 Beavers June 3, 2020

I figured I’d mostly be basking yesterday. And that if I had any laurels at all I’d be resting on them. Then I got an email from Holly Hewes at Lindsey Wildlife who said she had heard about my presentation for Napa and would I be willing to present for them? She had grown up in Oregon and loved beavers, and had worked the festival before. Lindsey does a volunteer meeting once a month and try to have speakers as well. Would I be willing to present beavers in an August zoom meeting?

Sure. Just call me Zooming for beavers, that’s me.

I vaguely remember presenting to lindsey once before, as far back as 2008. I’m a big believer that they should know MORE about beavers. Of course I said yes and suggested she read Ben’s book. Also that they should be selling it at the gift store.

Dam, I’m still waiting for my kickback check, Ben.

BEAVER MANAGEMENT IN CONTRA COSTA COUNTY

heidi08 Beavers June 2, 2020

Well?

Well, how did it go? The big meeting between you and the county supervisor and the heads of flood control and the American Rivers manager and the California Urban Streams Partners. How did it go when you talked about other ways to handle beaver issues besides killing them?

Pretty dam good, that’s how.

Long Term Solutions

I got to present first. I was asked repeatedly about details. People were surprised about population information, surprised that dams blow out in high flows, and surprised that things worked as well as they did in Martinez. The other presenters said my power points was beautiful and the head of flood control personally thanked me at the end of the meeting for making her job so much clearer.

Honestly, it was that good. I don’t know if this means the next beavers will have a better time of it, but it should give them a fighting chance anyway. Fingers crossed.

At the end of the meeting the American Rivers rep recommended that all county decisions to depredate beaver should have to go through a review board and I just  gaped at that. I’m a dreamer, but not a pipe dreamer. But it was fun not to be the most rabid beaver voice in the room.

Oh and for my reward, Rusty of Napa snapped two photos of the kit last night. Enjoy,

GROOMING FOR SUCCESS: BEAVER VERSION

heidi08 Beaver Grooming June 1, 2020

A beaver grooming is a regular site to see and as likely to be photographed as a beaver chewing or a beaver building a dam. Maybe more likely, since grooming happens on land and people are way more impressed at beavers on land and likely to snap a photo. Grooming isn’t about vanity, it’s urgent beaver business. Life or death self care. If it didn’t happen every day, especially in the colder places, the beaver couldn’t exist.

You’ll be happy to know that such an important job comes with the exact right tools for the job. The so-called grooming claw which is a split nail on their back foot that is perfect for fluffing up that fur. We were recently treated to an excellent grooming profile from the Winterberry Website,

Beavers Grooming and Specialized Split Claw

Beavers groom frequently, both in the lodge and on land, to remove debris from the coat and to waterproof it with oil from anal glands. When the animal emerges from the water to groom, it may start with its face and head, or with its belly. It begins by raking the fur with its fingernails, and then gets some difficult to reach spots with its hind feet. The two inner toes on each hind foot are modified for grooming. The innermost toe nail opens and closes over the toe, like a bird’s beak, and functions like a coarse toothed comb. The second toe has a “split nail” or “double nail”. The former term is more commonly used but the latter term is, perhaps, more accurate. It really is a double nail: It has a true nail and an additional horny growth between the true nail and the toe. The additional horny growth has a finely serrated upper edge which serves as a fine toothed comb.

Of course a beaver grooming is a camera ready moment, but two beavers grooming eachOTHER, well that just resets the whole scale for cuteness. She says beavers mostly do mutual groom in the lodge, but we know that’s not exactly true.
