Aquatic life near a mine pit lake underwater beaver lodge

Steve Kohl

Brainerd Dispatch staff phtographer (and diver) Steve Kohls filmed the aquatic life near a mine pit lake underwater beaver lodge. See suspended sunfish, thousands of minnow and lurking bass all hanging out in their aquatic underworld.

The powers that be will not let me embed that video, so click on the picture and go see it yourself. Honestly, it’s worth it. Just look at the biodiversity of life near that beaver lodge, and remember the amount of mud and soil beavers excavate to maintain a lodge or access a food cache in winter. Beaver digging makes diverse invertebrate communities which make divers FISH communities.

Now remember that this is the Cuyuna Mine Pit lake in Minnesota. Cuyuna was a mine dedicated to excavation of iron ore which like most mines has all kinds of pollution fallout – including something charmingly called “acid mine drainage”. Could Cuyuna do anything better to restore those damaged pits? I think not. Thank you Steve Kohl, for this great proof of beaver biodiversity!

Castor Anglicus took my advice and set Adrian’ Forester’s recording to photos. Love the headlines and the awesome images. I’m wishing it had some video and slicker editing, but I’m very picky and the news stations should leap at this.

Speaking of news, yesterday I met with ABC channel 7 down at the dam to talk about beaver, water, and drought – as well as plug the festival. It was one of those fun interviews where the interviewer started out disinterested and nonplussed by his assignment, and ended up eager and fascinated, running up and down the creek photographing birds, talking to onlookers, and asking for a bumper sticker.

I hope his conversion means there will be a nice segment on prime news, but you never know. He kept shaking his head and saying “You’re amazing on camera! You answered every question so succinctly!”Which made me smile a little and think of the old Paula Poundstone line….

“Last night’s show was an amazing crowd. I did an hour and a half. I could have done more, but the club had really bad security and a lot of the audience got away”.

I’ll let you know when it’s airs. Hopefully Thursday.

Oh, and in the mean time you need to see this. Honestly. You. Just. Do.

Public Works: The Amazing Self-Powered Garbage-Trapping Machine

Meet the trash-collecting contraption that’s cleaning up Baltimore’s harbour.

Invented by Clearwater Mills LLC, the Interceptor floats at the mouth of the Jones Falls river, through which garbage used to flow into the inner harbour. Now booms (floating barriers) direct debris towards the 4.3-metre-tall garbage collection machine. Spring-charged rakes claw the refuse onto a conveyor belt, which is powered by a water wheel spun by solar-powered pump. The belt carts the garbage into a dumpster, which, once full, is dragged by boat to a waste-to-energy conversion plant.

How awesome would this be at the Marina? Some adaptions would let it run on tides twice a day. Shell could pay for it, New Leaf Academy could promote and maintain it, and Martinez could be the east coast premier of another dam good idea.

Let’s start with a word from duck hunters. Now everyone I’ve shared this with has reacted with a “let the ducks live” remark, but you have to realize the pragmatic value of articles like this. Right now we need ALL the beaver supporters we can muster, so if people let them be because they want more fish to catch or ducks to shoot, we should realize that they’re still allies. Beavers make strange bedfellows.

Ducks in Small Places

Matt Gnatkowski

One of the best friends of hunters who like to hunt ducks in small places is the beaver. Industrious beavers create a lot of ponds and sloughs that make for perfect out-of-the-way duck habitat. Mallards, wood ducks and black ducks like using the flooded timber created by beavers. To find these duck hotspots you need to scout constantly. Keep track of where you see beaver activity during grouse hunting trips, during the bow or rifle deer seasons or when snowmobiling, and make it a point to visit them during the waterfowl season. If ducks aren’t using the ponds when you arrive, wait until evening. Many times the birds will be off feeding elsewhere and return to roost on the pond toward evening. The sky can be full of birds as the sun slips behind the horizon.

Wildlife biologists can steer you toward areas that have high beaver numbers. Talk to hunters, trappers and anglers who might be able to lead you to beaver ponds. If practical, you might want to even rent an airplane for a short jaunt around areas of beaver activity to pinpoint ponds. Beavers can create a lot of small-water duck havens in a short period of time. Where there was only a trickle of water today can be a pond of several acres tomorrow. And it won’t take long for the ducks to find it.

Let’s face it. Duck hunters have more powerful friends then we do. They have magazines and sponsors and legislation and fawning politicians. And would it be so horrible if more duck hunters made the intuitive leap to realize that fewer beavers mean fewer ducks? No, it would not. I realized when I read Three Against the Wilderness that wise hunters and trappers could be among our best allies – once they got the message. And in order for that to happen we need to stop being mortified enough to talk to them.

Consider this website de-mortification training.

(It’s a strange thing to be realizing in the same day that duck hunters help beavers and the Nature Conservancy kills them. But there it is. Life is full of surprises.)

On to Whidby Island in Washington State where so many folks are fond of beavers they don’t know what to do with them.

A beaver lodge sits at the southern edge of Miller Lake, about 30 yards from a beaver dam. Lake levels are on the rise, and along with other impacts, are raising concern among South Whidbey residents.

Whidbey’s beaver population: residents chew on problem, seek county help

“When there’s nature and people, you have to come up with solutions,” Kay said.

In some cases, however, beavers have won friends. A population at Miller Lake is credited with vastly expanding the lake, but also creating water views. For Bob Olin, the edge of his backyard that borders the lake was once dominated by poplar and willow trees. They are all now long gone.

“There were 10,000 of them right out there,” said Olin, motioning to his backyard. “No, I’m quite happy with the beaver,” he added.

Jamie Hartley, critical areas planner for Island County, said county code defers to the Washington Department of Fish and Wildlife for its guidelines. The state allows residents to shoot or relocate beavers as a last resort to other types of mitigations, including the installation of culverts or beaver deceivers.

Steve Erickson, with the Whidbey Environmental Action Network, said that shooting or trapping the occasional beaver is not going to really impact the population. However, farmers need to learn to deal with changing conditions and coexist with the beaver population.

“The idea of a pretty farm where it’s all static and never going to change is a fantasy,” Erickson said. “People are going to need to change the way they are dealing with nature and work with it.”

And that, ladies and gentlemen, is why Washington is the most beaver-intelligent state in the nation – maybe world. Apropos of nothing, the beaver friendly Whiby website “Tidallife” has our website in their blogroll and it’s how we get a significant number of visitors every month.

Now back to Devon, where musician Adrian Forester has this to say about the River Otter beavers.

I’m trying a new spam filter on comments this morning, and it appears to be working. Every day we get about 20 comments that I have to weed through from spam-bots telling me to buy sexual aids or that my site could get more hits if I did X.
