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

Month: March 2020


Discovery is one of the finest parts of watching a beaver pond. Whether it’s coming across a new bird species that you never saw before or watching a river otter for the first time hunting for a tasty fish, to truly observe a beaver pond is to discover, like an expedition to the north pole, things that you never saw before.

I was never bored at the pond. Looks like I wasn’t the only one.

Illuminating the Hidden Forest, Chapter 39: Springtime for beavers and frogs

We are living in a moment where some lives feel as though time has slowed to a crawl, while others must feel that time is careening at warp speed. For those of us sequestered in our homes, time passes slowly. For those separated from critically ill loved ones struggling for air in hospital beds, time must pass more slowly still. Those on the front lines in those overburdened hospitals must feel as though time is speeding by as they race to take care of their patients or to get their urgently needed supplies.

In nature, though, time unfolds at its own pace (though global warming is affecting that as well). Walking in the forest during this crisis can provide a kind of correction for our situation-driven extensions and compressions of time.

Take beavers and frogs, for example.

What a lovely way to start an article. I’m all ears. Go on…

Last week, a sleek, lively, young beaver found a nice niche under a bush at the side of our small lake. As soon as Lily came barking and we stood up to look, he bounded into the water with a slap of his tail, circled inquisitively and finally returned unperturbed. To our relief, it seemed that he had left to search for a better place to make his new home.

Then, two days ago, alerted again by Lily, I saw a large, furry body in the same recess under the bush, bigger than before. This furry body didn’t leap into the water at Lily’s barking like the earlier beaver, but curled into a tighter ball, pressing its face into the cavity of earth. At first, I didn’t know that it was a beaver until it showed its blunt and solid face.

My grandson and husband came down to check. The beaver seemed to be aware of us, but lethargic. It would open its eyes a bit, maybe press its head further into the niche, then roll on its side, head clearly visible, eyes closed. We worried: Is this beaver sick?

 

Hmm I have run into stories of a couple beaver sleeping outside. Sometimes when their lodge is destroyed. Sometimes when they’re in transition. Sometimes when they’re someplace without any other option. Looks like she did her homework.

A few minutes later, as I circled on the bank close above the beaver, it dropped into the water and swam rather lazily across to the other bank where it found another hollow to curl up in and, it was now evident, to snooze.

A little research in our beaver books gave us an explanation. Young beavers leave the lodge at two years to find a mate and create a new home where they will have kits the following spring. That was our first beaver. A year later, when the female is due to give birth, the male usually leaves the lodge for a few days and returns after the kits are born. Our guess is that our second guest is a mature beaver taking a reverse paternity leave and will be gone in a few days. We shall see. Another possibility is that we are the guests and that our beaver has plans to stay.

You should be so lucky! I like that possibility the best. And so would the rest of your pond inhabitants.

The frogs also have their spring timetable, and to our joy and amazement, that time is now. Descending from Balance Rock to the beaver pond in Kennedy Park this morning, we heard a din of honking as we approached the pond. We thought it might be a flock of Canada geese flying overhead. We stood by the pond, gazing into the blue sky, but could see no geese. Then we realized that the sound came from below, from the pond, and there they were: hundreds of frogs floating and darting on the surface of the water, croaking their hearts out. And they were LOUD! They have just emerged from hibernation, and the males are serenading the females, full of spawn just waiting for fertilization. Here is a YouTube link to a video that I took at the pond.

This was so magical, so marvelous, that we had to tear ourselves away. A chorus of frogs emerging from the mud in spring reminded us to pay attention to what we have, to be grateful for the beauty frogs and beavers bring into our lives, and to cherish the moments when we, too, can emerge from the mud and sing.

Nicely done Carolyn Newberger. I love reading beaver observations that tie themselves closely to our own lives. We are nature. And spending time in nature is spending time with ourselves, after all.


Notice anything different? Maybe something deep blueish? The website got its background color back yesterday! Hurray! Someone in IT just got over being sick or outsourced her job to South Korea where they’re actually getting BETTER and I was able to make the color stick on sunday. So very happy.

I got something about Singapore’s new River Park yesterday and felt very pleased with my detective skills. The flyer said that it had a river cruise where you could “Feed Beavers” and I thought hmm that’s not really very likely. Since there are no actual beavers in Singapore and beavers are nocturnal, Whatever sorry animal you can feed probably isn’t beavers.

I was very pleased with myself when I found this:

Heh heh heh. What that means is that wildlife parks will sell you anything for a paycheck I guess.

These are dark days and we all need to have our spirits lifted. Check out how this remarkable school choir is coping with the quarantine.

I remember a great deal about my time with the beavers: the stress of fighting the city, the delight of watching them build and interact, but every now and then something jars loose a detail that I had completely forgotten. It’s rare, but it happens.

This article from Alabama made it happen.

Beavers engineer new creek system at Ruffner Mountain

Wild mint grows by the stream where the beavers live at Ruffner Mountain.

The smell is crisp and alive there, and washes over a scene of renewal inside one of the most fascinating urban nature preserves in the Southeast. Ruffner Mountain was once a wasteland mined for iron ore and limestone. Now it is a refuge for wildlife and biodiversity, and a resource for Birmingham residents who need a good walk in the woods.

We could all use one these days.

Isn’t that beautiful? There was wild mint in the tiny grubby bank downstream of the main beaver dam.I remember standing there with wafts of it when I’d inhale. The beavers never seemed to eat it. But it volunteered itself into the muddy banks among the rushes. Because the homeless also used those recessed banks there were sometimes unlovely smells there too, But the mint refreshed them, and made them clean again. I had forgotten that mint.

The beavers are the newest, most exciting addition to Ruffner, and they have quickly, in a matter of months, set upon doing their beaver things. They have cleared out dozens and dozens of trees in the wetlands, and built, by my count, 13 dams.

The wetlands have expanded gradually over that time, and below the third in a series of three ponds, is where the beavers have built their run of nine dams leading into the forest. The effect of all this hard work is remarkable. What once was a tiny trickle of a spring is now a growing creek of incredible beauty.

I call it the Ruffner Mountain Beaver Locks because each dam is strategically placed to create something of a step-down system of pools like a miniature Panama Canal. Little furry geniuses, these beavers.

Oh man that sounds beautiful. No photos with this article but we can imagine the series of interlocking dams can’t we? Remember this article is from Alabama, a place not exactly famous for its beaver appreciation.

The wetlands are located on the south side of Ruffner Mountain. Most people who visit the urban nature preserve are familiar with the amazing quarries on the west side of the park and the nature center to the north. If you visit the wetlands, please be respectful of the beavers and the habit they are building.

In truth, the wetlands are not natural at all, but a consequence of the abandoned mines on the east side of Ruffner Mountain. The mines flood, and water pours out from the ground and collects in the ponds. One such mine spring is channeled through old iron piping and gushes from a release valve that looks like a relic from the 19th century.

Perhaps it kept the mines dry 100 years ago. Nature has found a new use for it now.

Downstream of that water source is where the wild mint grows in bunches, and beavers have made it their mission to create a new world amid a city on hold.

Beavers take over and make repairs. I sometimes wonder what would Alhambra Creek look like now if we hadn’t stopped them from their work. The water would have crested Castro and easily reached the County Recorder Office. Maybe it would have topped the bridges entirely and refilled that incised creek to reopen the flood plane that has been missing 100 years.

I might have looked like water world. I know it would have smelled amazing.


Mary Obrien was the lode star that guided my path to beavers. And before she was mine she was many. many others teacher and inspiration. This is her last year at the Grand Canyon Trust because she will retire on her birthday in December, so I thought she needed deserved something special. Mary will continue to volunteer her services until long past her dying day Imagine, but this is a fine place to consider her acumen.

Torrey Ritter, now of Montana Fish and Wildlife put this lovely snapshot together. Turns out Google Maps is a good friend of beavers. Here’s what he had to say about it:

Over the past few weeks, I have tried to highlight some of the bountiful benefits of beaver activity for streams and riparian areas. But it is difficult to fully see and appreciate the magnitude of the impacts beavers can have when it comes to water storage, sediment retention, and habitat enhancement. Luckily for us, there are giant conglomerations of metal outfitted with doo-dads, gizmos, and what-nots hurtling around the earth taking photos from a perspective we rarely get to experience. I am talking about satellites (and sometimes airplanes), which capture some of the most beautiful sights on planet earth. If you haven’t spent time exploring around in Google Earth learning more about the landscape you call home… do it!

One of my favorite Google Earth pastimes is looking for cool examples of beaver colonies. Every stream system is unique, and beavers take those unique systems and create amazingly intricate colonies that display the complex interactions between water, sediment, and vegetation. The result is nothing short of natural, abstract “art”. The patterns of water impoundment and woody plant harvest are beautiful in their own right, but they also demonstrate the incredible ability of beavers to keep streams connected to their floodplains and create a variety of habitat types for a range of plant and animal species to enjoy.

Here is a small selection of some of my favorite beaver colonies I have come across while zooming around Google Earth in west and southwest Montana. The water flows from left to right in each photo. In these times of stuck-at-homeliness, I highly recommend getting yourself into some aerial imagery and having a look-around. You will be amazed at the perspective it gives you on the world.

And if you find a particularly beautiful beaver colony, please share it! #stuffbeaversdo #TuesdayswithTorrey
