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

Category: Beavers and Frogs


Well, I’m sure you’ll have plenty of other opportunities, but this is an important one. Before we get down to work and roll up our sleeves, let’s have dessert first.

Searching for beavers on the Quabbin Reservoir’s restricted Prescott Peninsula

About 20 DCR biologists and volunteers stomped to shake off the cold Sunday morning, standing in a ring outside a small shack on the Prescott Peninsula as Clark set the plan for the annual beaver survey. Teams would split off, tramp through the woods to follow their respective streams, take down data on any active beaver lodges, then return to the shack for lunch.

Beavers were non-existent in Massachusetts for more than a century due to hunting and trapping, plus elimination of habitat. After the valley was flooded in the late 1930s, the beavers returned.

Clark said that after the beavers came to the reservoir, the population followed a pattern typical of reintroduction — explosive growth, followed by a crash as the habitat is oversaturated, then a steady leveling off.

No way, are you suggesting that the population actually regulated itself? Without trapping? Even when the Massachusetts voters imposed new restrictions on trapping in 96 and the population was supposed to explode? This is pretty outlandish stuff. Just how long have you been collecting this spurious data?

The first Prescott survey was held in 1952. The survey has been annual since the early 1970s, and some of Sunday’s searchers have returned every year for 30-40 years.

Holy Guacamole Batman. You mean they have 62 years of data on beaver population? And the effect of conibear restriction is somewhere in the middle? You know a statistician worth his pocket calculator could easily whip those numbers into a regression analysis that disproves the accepted lie about beaver population exploding after the new rules were applied? You do know that, right?

Well, maybe the reporter got that wrong. He seemed really distracted by the meat balls. He does say that people aren’t normally allowed in the area because it’s in the watershed. Ahem. (News flash:Every place on this planet is part of a watershed. Just so you know.)

Everyone ready? It’s November 18th so that means you still have 12 days left to tell Wildlife Services that their rodent management plan is ridiculous, oblivious  of the environment or science, and barbaric in the extreme. But those are just my words. You’ll find your own. Here’s Mike Settel from Idaho talking about what’s needed.

In Wildlife Service’s newest justification for ridding us of beaver you can find that bit of humor and others in a recent request for public comment on Wildlife Service’s “Aquatic Rodent” EA for North Carolina.

Don’t attempt to e-mail your comments because, according to their deputy director for environmental compliance Alton Dunaway, receiving comments only by FAX and snail mail will “modernize” their public involvement process. I recommend Faxing comments to (919) 782-4159…However, an e-mail you may find useful is for that of the author, Barbara Schellinger. 

Even though it is a North Carolina document, the rationale proposed sets a precedent for mis-information and obfuscation regarding wildlife management. Please FAX your comments and request that WS includes non-lethal mitigation as beaver solutions, provide current data showing beaver harm salmonids, and prove that beaver dams increase sediment pollution (there are other spurious claims that are suspect or dated, but you should read those for yourselves). Regards, Mike

Thanks Mike for putting us on the right track. Remember, what they get away with in North Carolina will become precedent everywhere. I will share just a little bit of their ignorance, but you should really go read the report for yourself here:

The Wisconsin Department of Natural Resources guidelines for management of trout stream habitat stated that beaver dams are a major source of damage to trout streams (White and Brynildson 1967, Churchill 1980). Studies that are more recent have documented improvements to trout habitat upon removal of beaver dams. Avery (1992) found that wild brook trout populations improved significantly following the removal of beaver dams from tributaries of some streams. Species abundance, species distribution, and total biomass of non-salmonids also increased following the removal of beaver dams (Avery 1992).

Beaver dams may adversely affect stream ecosystems by increasing sedimentation in streams; thereby, affecting wildlife that depend on clear water such as certain species of fish and mussels. Stagnant water impounded by beaver dams can increase the temperature of water impounded upstream of the dam, which can negatively affect aquatic organisms. Beaver dams can also act as barriers that inhibit movement of aquatic organisms and prevent the migration of fish to spawning areas.

Wow. Give it up for the USDA and author Barbara Schelllinger who was willing to dig back through 47 years of research to find the  completely bogus paper she just knew to be true! This woman is no slacker when it comes to bravely lying about beavers. Good lord, the letter almost writes itself. Although I personally feel that Issue 7 deserves the lion’s share of our attention.

Therefore, the breaching or removal of a beaver dam could result in the degrading or removal of a wetland, if wetland characteristics exist at a location where a beaver dam occurs. The preexisting habitat (prior to the building of the dam) and the altered habitat (areas flooded by impounded water) have different ecological values to the fish and wildlife native to the area. Some species may benefit by the addition of a beaver dam that creates a wetland, while the presence of some species of wildlife may decline. For example, darters listed as federally endangered require fast moving waters over gravel or cobble beds, which beaver dams can eliminate; thus, reducing the availability of habitat. In areas where bottomland forests were flooded by beaver dams, a change in species composition could occur over time as trees die. Flooding often kills hardwood trees, especially when flooding persists for extended periods, as soils become saturated. Conversely, beaver dams could be beneficial to some wildlife, such as river otter, neotropical migratory birds, and waterfowl that require aquatic habitats.

beaver in barDingDingDing! I found the opening! (Well, one of many actually.)  See in their effort to say “it’s a wash, really” beaver dams HELP some species sure, but they HARM others. So getting rid of them is a zero sum game with totally justifiable consequences. Just take the darter for instance!

Darter!

Maybe we’re the only ones that remember there’s this famous case from Alabama in 2008 where the city of Birmingham was sued by The Department of Conservation and Natural Resources (among others) for upwards of a million dollars over removing this beaver dam that was protecting  thousands of the rare endangered watercress darters. In the end the case cost the city some 4,000,000 dollars and dragged  out in court over 4 years. Am I ringing any bells, does this sound vaguely familiar?

The city “knew or should have known that removing a beaver dam and surrounding natural structures would potentially disrupt the water level of the Basin and its inhabitants,” the agency claims.

CaptureDam [sic],  this is gonna be fun. If you want to share your letters, send them to me and I’ll make sure they’re visible. I’m sure WS is hoping they can make it all the way to November 30th without hearing from you. Let’s disappoint them, shall we?


conference 2014The agenda is out for the State of the Beaver Conference 2015 and it looks amazing. Starting with the Keynote speaker Lixing Sun, the co-author of the most famous beaver book yet written. (Books really, because it’s so popular there’s a second edition.)

 Now maybe you’re thinking”why should I care” or “I hate Oregon in February” and “I don’t need to hear the latest beaver research”. But if you were thinking that you’d be thinking wrong. I’m going to assume that whoever you are you drink water, live on a rapidly heating planet, and are a citizen of a government with limited resources for fixing those things. The world needs beavers, and the only way it’s going to get them is if people like you stand up and teach people why they matter and how to live with them. This conference will make you better at that and you’ll hear from great minds like,

 Not to mention that it looks like this morning I just managed to get Derek Gow from Cornwall on the schedule. So you’ll be personally updated on the most famous beavers in the world. As well as a watershed-beaver introduction by this persuasive gentleman:

The conference is truly one-of-a-kind, inexpensive, and ecologically  invaluable. The hotel is nice and beaver friendly, the casino thinks beavers are good luck, and you will meet amazing people that will become amazing friends. Register here and I’ll see you in Canyonville!

2015 SponsorsNow there is lots more to say, including beavers being threatened in BWW’s home town, (if you can believe it) and moderately good news from DEFRA about the Devon beavers. but I wrote this post this morning at 7am, worked on the graphics for leonard and promptly  lost it the entire column in the ether so had to do EVERYTHING again.

This beaver reporter needs a break.


Beavers are busy preparing for winter

With the arrival of killing frosts, animals have gone into high gear preparing for the tough conditions soon to follow.

 Those who are feeding birds have observed their sunflower seed supply rapidly dwindle as Blue Jays repeatedly fill their crops only to fly off and cache their loads. Gray Squirrels are also busy, frantically seeking the last of the acorns to stash in the ground.

 And Beavers are busily harvesting trees as they build their winter stores.

The author of this article, Michael Runtz, is a friend to wildlife and to beavers in particular. We’ve connected in the past and corresponded about his work. He’s been photographing and watching beavers for 20 years, and his lovely photos were featured in the recent beaver documentary on PBS. The last I heard from him his book on beavers was due out any minute. But I guess while we wait for that we should savor this interesting fact.

Surely the presence of alders in food piles is sufficient evidence that Beaver’s prefer them in their diet?

 Actually, it is not. When food piles are examined, the surface portion often contains inedible items such as cedar and fir branches. And previously enjoyed (barkless) branches also adorn them.

 The most edible items are actually hidden deeper under the surface of the pile where they will not become locked in ice. That is where poplar and willow branches reside; these will be extracted from the pile all through the winter.

This is worth remembering. The good beer is always hidden in the back of the refrigerator.

waterboardsThis is the Elihu Harris building in downtown Oakland. It houses some of the most essential state government offices, like the Equalization board, the Alcohol and Tobacco board, The Unemployment board, and the Water Quality control board. That’s where Ann Riley works as a Watershed Stream Protection Advisor.

One portion of the Water Quality board is dedicated to what’s called the “Beneficial Use of the state’s waters”. Which covers areas like fish and water-dependent wildlife. Riley is a huge beaver supporter and invited me to be part of her panel at the Salmonid Federation last March. Now come December guess who just got invited to talk to them about a new potential partnership with beavers?

I can’t tell you what a big deal this sounds like in my head. I immediately thought of all the things that could go wrong: I could mess up, lose my voice, my computer could break, it could be cancelled, there will be no one there because it’s the holidays, I got invited because something bad is going to happen, etc. But it doesn’t matter. Beavers are coming to the water boards.

And it’s a big deal.


CaptureIf I were the editor of Conservation Magazine, I would have a regular feature in every issue called “Who do beavers help now?” Wouldn’t you?

Beavers help out young frogs

Beavers are a boon to the environment: Their dams create ponds that provide homes for birds, amphibians, and other critters. Now scientists have found that beavers also aid their wetland companions by digging canals that young frogs use to hop from ponds to forests.

The canals, which allow beavers to transport branches and hide from predators, can stretch over hundreds of meters. But “the effect of canals on wetland ecosystems has received little study,” the researchers write in Animal Conservation. If the canals help beavers move around, they wondered, do they also help amphibians? For instance, wood frogs are born in ponds, but they must find their way through meadows to forests where they can spend the winter.

…researchers spotted six to nine times more young wood frogs on canals than along pond shorelines without canals.

Well, well well. Beavers help frogs. Who would have guessed? Oh, that’s right, everyone with a pulse. (Except for Roseville where beavers were killed in 2012 to protect frog habitat in vernal pools.) Thanks to Amy Chadwick of Montana for sending me this article. I would be happy for the ammunition, but I know better. If the beaver battle were about having enough research it would have all been over decades ago. In more cases than you want to imagine, facts don’t win the day.

Fears do.

But a well told story might. (Speaking of which, I just reviewed that article on vernal pools I wrote two years ago. It was sadly so much better than what I’m going to write this morning, you maybe should too.)

Here’s something else that beavers help, this photo is from Rusty of the beaver ponds at Napa he is keeping an eye on. He cleverly remarked that this was going to have to be his own version of Gravity Glue balancing stones. Obviously beavers help the wildlife supported by this pond and every other hang in a very delicate balance.

If you’re like me you’ve been noticing the increasingly bright shine from above every night. Tonight will be the Full Beaver Moon, so named either because it was a good time to set traps for the winter OR the beavers were so busy making their underwater food storage. You know which one I prefer but step outside for a moment tonight and appreciate what it means to be under a beaver moon.

IMG_0348Yesterday I received a very interesting email from Pam our fiscal manager at ISI who said that she and Loren had attended the fundraising breakfast for Daily Acts where they had been surprised to see our friend Brock Dolman on stage dressed in a beaver costume and talking about the good beavers do. She snapped this shot with her phone and you can see the beaver’d Brock wayyyyy at the back. She also said there was video of the event and we should get it soon.

You might remember Pam helped at the festival and trekked to our planning meeting beforehand. She had been such a help in our transition aboard that when she admired my wildbryde keystone species charm necklace I had given it to her. She wore it to this event and guess what happened?

And your name is quite well known. I wore my beautiful charm necklace, of course, and a little girl there told me she made her own at the Beaver Festival! Several other adults had also attended. …I am happy to be associated with your fine organization 🙂

How cool is that? Someone wearing our charms  was spotted by a child who had made them herself! And former attendees of the festival were at the breakfast promoting our good work! Now that’s an awesome coincidence. And it’s what I call being surrounded by beavers!

More good news came from Sherry Guzzi in Tahoe. You’ll remember that she and Ted had installed flow devices at Taylor Creek where they had been battling beavers for decades and ripping out dams to protect nonnative kokonee salmon. They had waged an epic [and I do mean epic] campaign to win hearts and minds and were finally begrudgingly given the go ahead “try one” in a back channel. Of course this worked like a charm so they were granted permission to try one on the main channel. Guess what happened?

 I want to personally thank you so very much for all your hard work, coordination, communication, perseverance and good humor. It has been a pleasure working with you to create more harmony between the visiting public and beaver at the Visitors Center!

 I am excited about the other opportunities to collaborate that we’ve been exploring. Your assistance in addressing beaver concerns at other locations in the Basin will be warmly welcomed. 

 

Is it possible that in a million years I never expected this response and I simultaneously have imagined no other? Fantastic work Ted and Sherry! And everyone else who helped nudge, wheedle, persuade, cajole and shame this into happening. Finally the Taylor Creek beavers can live in peace!

And a final note of warm remembrance for car guru and radio humorist Tom Margliozzi, who  died yesterday from complications due to Alzheimer’s. Everyone remembers his infectious laugh and his playful advice but I don’t think that was his real talent. Tom and his brother were both MIT graduates. They were realists who loved science and solving problems. Tom was educated without being elitist. Regional without being exclusionary. Populist without be simplistic. Traditional without being dated and funny without being mean. In three minutes Tom could connect with a Lexus driver in NYC, a Ford pickup driver in Alabama, or an Honda driver in Chicago. There are a handful of people alive in our partisan world that still have that skill. He perfected it.

He is remembered on this website with his badge of honor. The brass rat.
