Note: This is part two of a two part post. If you’d like to see part one you can scroll down to it.

1. Beaver Dam

If you walk long enough on the old abandoned road through Yale forest in Swanzey you’ll come to an open swampy area that was once home to beavers. Beavers will move into a place and eat all the trees and then move on. Their pond will eventually drain and new trees will start to grow, and they will move back again to repeat the cycle. I’ve read that it takes about thirty years to go once around the cycle and this area looks as if it’s in the beaver pond draining stage. Now trees need to grow so the beavers will come back. The above photo shows the old dam which isn’t really holding back any water now, judging by the force of the stream that runs through here.

2. Beaver Swamp

The height of the embankment in the background of this photo shows that the beavers chose a natural bowl shaped area for their pond, but the grasses in the foreground show that the pond is now mostly dry.

3. Beaver Dam

This is another look at the dam. It was long but not real high; maybe 4 feet. I’ve seen them high enough to be taller than I am, holding back an incredible amount of water. The biggest beaver dam on record is one in Wood Buffalo National Park in Alberta, Canada that is 2,790 feet long and can be seen in satellite footage from Google Earth. Explorer Rob Mark was the first human to reach it in July of 2014. I hope I’m never near a beaver dam if it lets go.

4. Beaver Tree

There was plenty of evidence of beaver activity but it happened a while ago. This beaver stump is beginning to blacken, as were all the others I saw.

5. Log Pile

Tree cutters of a different kind were also in evidence. I don’t know why they left these logs there. The wood must have been sub-par in some way.

6. Log

A couple of the logs showed signs of fungus infection. This one had signs of what looked like it might have been blue stain fungus (Ophiostoma,) which is usually transmitted by bark beetles. It is also called sap stain because it discolors the sapwood, along with any boards that are cut from it. This lowers the value of the log considerably; possibly enough so it wasn’t even worth the fuel it would take to truck it to the mill yard.

7. Pine Bark Beetle Damage

There was plenty of evidence of bark beetles on pine limbs. Not only do they transmit disease, if they chew one of their channels completely around a branch it will die from being girdled.

8. Claw Marks on Log

Another log had claw marks on it. They puzzled me because the snow was ice covered and too hard for an animal to have left prints. I’m guessing raccoon or maybe a bobcat; they were quite small, but bigger than a housecat would have left.

9. Club Moss

Clubmosses held their heads up above the snow. This one looked like Lycopodium obscurum, commonly called ground pine, even though it has nothing to do with pines. It is also called rare clubmoss though I don’t know why, because it is everywhere.

10. Fern in Snow

The evergreen ferns are showing great fortitude this year. When I see one this way it looks so delicate but the snow and ice surrounding it tell a story of unsuspected toughness. They’re very beautiful against the white snow and add so much to the winter landscape. I’m glad they’re so tough.

11. Dead Ferns

Even dead ferns add interest to the winter landscape. I like seeing their deep reddish brown color against the lighter tans of the grasses. It’s a simple thing that brings joy and puts a spring in my step.

12. Pixie Cup Lichen

Pixie cup lichens (Cladonia asahinae) poked up out of the hair cap moss like tiny golf tees. I was hoping they would be fruiting so I could show you how they reproduce, but not yet. They, like many lichens, produce spores in the winter but it must happen later on. I’m not very good at keeping track of such things.

13. Striped Maple Bark

Striped maple (Acer pensylvanicum) has striped bark but I’ve never seen it come with blue stripes and I can’t find any reference to blue stripes on line. They are usually a cream / white color but will eventually disappear as the tree ages. I took this photo to show how dark the reddish brown bark of striped maple is when compared with other trees, such as the one on the right. This maple often grows in the form of a shrub here and might reach 15 feet tall on a good day. Another name for it is whistle wood because whistles are easily carved from the wood of its branches.

14. Striped Maple Buds

I knew that the buds and young twigs of striped maple were often tomato red but I’ve never seen spots on a bud before. This isn’t a very sharp photo but at least you can see the spots.

15. Brocade Moss

It looked like someone had embroidered this brocade moss (Hypnum imponens) on the log it grew on, and that’s how it comes by its common name. It’s a shiny, feathery moss that forms large mats, usually on wood but sometimes on soil. I’m not sure what the small blue bits are. It must have been ice reflecting the blue of the sky. I didn’t see them in person so I’m surprised that the camera did.

16. Turkey Feather

I was expecting to see some turkey tail fungi (Trametes versicolor) but this turkey feather was a surprise. There is a story behind it, but it’s one I’ll never know.

17. Oak Leaves in Ice

I was also hoping to see some crystal clear ice but it had been snowed on and re-froze with a textured surface more like pebbled glass than crystal, but I could still make out the shapes and colors of the oak leaves under it.

18. Stream Ice

The ice on the stream that used to feed the beaver pond was paper thin and wind sculpted. The animals are still having an easy of time finding water but are probably having a hard time getting around on the icy, crusted snow.

19. Pool of Reflections

A few woodland pools were ice free. They reminded me of the forest walks I’ve taken on moonlit nights when the moonlight shimmers and swims in the dark water of pools like this one. It’s something I haven’t seen in a long time but I’ve had an itch to try night time photography, so it might happen when the moon is full enough to light the way.
