Posts Tagged ‘Frozen Spider Web’

Anyone who has read this blog for very long knows I like to play on the banks of the Ashuelot River, which meanders through several local towns. Though when I was a boy it was terribly polluted, now people fish for trout along its banks and eagles can sometimes be seen flying over it. That’s why a few years ago I was disturbed when I saw an oily sheen on the water that filled my footprint on the shore. It looked much like the puddle I found on the shore in the photo above and I posted it on this blog, saying how I was hoping I’d never see such a thing on these riverbanks again. Then happily, thanks to several knowledgeable readers, I found out that this sheen might easily have come from natural sources. Iron rich ferrous hydroxide that occurs naturally in soil can cause the oil like sheen on water, as can bacteria which generate hydrocarbons in oxygen depleted soil. I was very happy to hear that because though I don’t want to see this river polluted, I do think that this film on the water is beautiful. Just look at those colors.

While I was at the river, I spotted trees that had grape vines loaded with grapes growing in them. Wild river grapes (Vitis riparia) like a lot of rain, and I know that because we’ve had a lot of rain and I’m seeing more grapes than I’ve ever seen before. The odd thing about it though, is how the birds don’t seem to be eating them. These grapes are a favorite of many birds and they are often gone even before I can get a photo of them, but on this day I didn’t see that a single one had been picked. That’s a little disturbing.

Also disturbing is how none of the Oriental bittersweet berries (Celastrus orbiculatus) have been eaten. They are another favorite of the birds and they disappear as quickly as the grapes, so why aren’t they? This vine is very invasive and can strangle trees to death so I don’t want it to spread, but I do wonder about the birds.

While I was there wandering along the river, I took a shot of the Thompson covered bridge, named after playwright Denmon Thompson, who was a native son, and built in 1832. The bridge design is known as “Town lattice,” patented by Connecticut architect Ithiel Town in the early 1800s. The open lattice work lets a lot of light into the bridge and this is unusual because many covered bridges are dark and cave like. In the 1800s being able to see daylight inside a covered bridge would have been the talk of the town. The Thompson Bridge is considered by many to be the most beautiful covered bridge in New England but the person who ran the wires must not have known that.

This bridge is known as the Cresson Bridge, also in Swanzey and also crossing the Ashuelot River. It was opened to traffic in 1859 and I wanted you to see it so you could get an idea of how dark it was inside these old covered bridges. The tiny square windows didn’t let in much light, and that’s why Town truss bridges like that in the previous photo were such an innovation, and why they were so welcomed by the traveling public. By the way, back in those day traveling was done by sleigh in winter, so snow had to be shoveled onto the plank floors of covered bridges so sleigh runners would have something to slide on. What a job that must have been.

I finally found a blue bead lily plant (Clintonia borealis) with a ripe berry on it and now you know why I call it “electric blue.” That might sound like the title of a Jimmy Hendrix song but it is a very unusual shade of blue, to these eyes at least. It seems to sparkle in the right light and it is a deer magnet. From seed to berry can take 14 years, with two of those years taken up by seed germination. This is not a fast-growing plant.

I went to see Baily Brook Falls up in Stoddard and was surprised to see how little water was actually falling. With all of the rain we’ve had I thought they would be roaring. I have a feeling that beavers are involved and if I walked upstream, I wouldn’t be at all surprised to find that they’ve dammed up the stream.

Since Bailey Brook Falls werent roaring I went to where I knew I’d hear the roar of water; the outflow dam at Swanzey Lake.

I’m always amazed by what I see when the leaves start falling. Here was a wasp nest as big as a soccer ball up in a maple tree, and I had been walking under it several times each day all summer long without seeing it. I’d bet its residents saw me though, and I’m glad they decided we could coexist. I was pruning a large rhododendron once that had a similar nest in the center of it. By the time I was able to stop running I had been stung on the back several times.

When the leaves fall from the trees the wind has greater force as it whistles through the bare branches and inevitably, small bird nests like these get blown out. I don’t know what bird made this one but you could barely have fit a hen’s egg in it. It was as light as a feather and very well made of grass.

I saw a spider web on a lawn and it reminded me of the synapses in my own brain. One of the questions that has been nagging at that brain for quite a long time is why nature uses the same shapes over and over again.

I looked down into the heart of a yucca plant and thought of the Native Americans who used every single part of this plant. They pounded the leaves and used the strong fibers inside them to weave sandals, cords, belts and baskets. They also ate the flowers and fruit of the plant. The sharp points at the tips of the leaves were used as sewing needles and the roots were peeled and ground and mixed with water to make soap for washing their hair and treating dandruff.  Sap from the leaves was used medicinally to stop bleeding and heal sores. Not a bit of it was wasted.

I found this colony of wooly alder aphids (Paraprociphilus tessellatus) on an alder limb in a swamp one recent day. Wooly alder aphids grow a white, filamentous waxy covering that looks like it’s made up of tiny white ribbons. A colony of them looks like white fuzz on the alder’s branches and this white fuzz helps protect them from the eyes of predators. They are sap sucking insects which secrete a sweet honeydew on the leaves and branches of plants. This honeydew attracts a fungus called black sooty mold, but since the mold grows only on the honeydew and not the plant, it doesn’t harm plants. The aphids themselves will do far more harm because they can literally suck the life out of a plant.

I’m not sure if the aphids with dots in this photo I took previously always look that way, if they haven’t grown the white waxy covering yet, or if they’ve lost the covering for some reason. They are very small; not even half the size of a house fly. I find them usually on the undersides of alder branches. If you are lucky enough to catch these insects in flight, they look like tiny white fairies. In fact another name for them is “fairy flies.” This is the best time of year to find them.

Here is something quite rare, unfortunately. American chestnuts were one of the most important forest trees, supplying both food and lumber. An Asian bark fungus (Cryphonectria parasitica) was introduced into North America on imported Asiatic chestnut trees and the disease all but wiped out over three billion American chestnut trees. New shoots often sprout from chestnut roots when the main trunk dies so they haven’t yet become extinct. Unfortunately the stump sprouts are almost always infected by the Asian fungus by the time they reach 20 feet tall but since some trees do bloom maybe these particular examples are growing from chestnuts. I found these three or four young trees a few years ago and have watched them get bigger over the years. They look very healthy so far. Though the leaves resemble beech leaves they are much bigger with very serrated margins. Many botanists and other scientists are working on finding and breeding disease resistant trees and maybe these trees will one day fit the bill. If you happen to find any you might want to keep an eye on them.

A tree “marriage” happens when two trees of the same species rub together in the wind. When the outer bark is rubbed off, the inner cambium layer of the trees can become naturally grafted together and they will be married from then on. The process is called inosculation and isn’t as rare as we might think. This example is special because it looks like the very tip of a branch on one trunk grew directly into the other trunk. It must have taken many years of strong winds and bark rubbing before they could grow together as they did.

Frost cracks happen when the sun warms the tree during the day and the temperature drops quickly at night. If you’re in or near the woods at night in winter you can often hear the trees splitting and cracking, and sometimes it’s as loud as a rifle shot. Frost cracks can heal in the summer when the tree produces a new layer of inner bark to heal the wound but then can crack again in winter. When this repeated healing and cracking happens over the course of a few years the buildup of new tissue can create a frost rib like that seen in the photo. I’ve seen them on several different species, so I don’t think any one species is more or less susceptible to cracking than others. It’s more a matter of how the sunlight falls on a tree’s trunk. Wrapping an ornamental tree’s trunk loosely in burlap in winter can help prevent the bark splitting.

If you grow stone fruits like peaches, apricots, plums or cherries then you should know the disease called black knot. It is caused by a fungus called Apiosporina morbosa. This fungus grows in the wild and its spores can be spread by rain or wind. The spores will typically infect trees from April through June on new growth. Infected stems swell up and produce hard black knots like that in the above photo. This disease can eventually kill the tree so infected limbs should be pruned off 2-4 inches below the knots and buried or burned before bud break the following spring. Black cherry seems particularly susceptible to the disease.

I saw a hollowed-out stump that was slowly filling with fallen leaves beside a trail. From what I’ve read in the book Bark; a Field Guide to Trees of the Northeast, by Michael Wojtech, eastern white pine (Pinus strobus) and eastern hemlock (Tsuga canadensis) are the only trees with stumps that will rot away from the inside out. It’s an interesting thing that I don’t see that often.

You would think that with all the rain we’ve had I’d be seeing slime molds everywhere, but actually I’ve seen very few this year. I believe the orangey brown material in this photo was once an active slime mold but by the time I found it, it was dry and hard. There are many different orange slime molds so it’s impossible to tell which one it is but it was still interesting. It shows how a slime mold will spread over its immediate surroundings, looking for food. Slime molds “eat” tiny unseen organisms such as bacteria and yeasts, and they are also said to help decompose leaves and rotting logs.

I’ve seen many thousands of pixie cup lichens (Cladonia pyxidata.) They’re the ones that look like tiny golf tees, but I’ve always wondered what they looked like when they first started forming. Did they always look like golf tees? I didn’t think so but I couldn’t say why. Then one day I thought I had found the answer. As you can see in this photo the little golf tees start life looking like simple pegs. You can see a few with tiny “cups” just starting to form. Pixie cup lichens are squamulose lichens with fruticose fruiting structures called podetia. Squamulose means they have scale like lleafy obes that often overlap like shingles. The parts that look like tiny golf tees are called podetia. Podetia means a stalk like growth which bears the spore bearing fruiting bodies. Finally, frucitose means a lichen with bushy, vertical growth. It is thought that some colonies of pixie cup lichens might be as old as 4,500 years. It’s good I think, to know a little more about these tiny life forms that see everywhere I go.

A boulder on the side of the road was covered by moss and though that might not seem surprising or earthshaking, it caught my attention.

Picture yourself in a small, single engine plane flying low over the treetops in the Amazon jungle, and you’ll understand why I was fascinated by this mossy boulder. I imagined that scene would look a lot like this.

Here’s a little hint of what’s to come. We finally had a frost, more than a month after our average first frost date and the second latest since such things have been recorded. But we haven’t had a freeze, and that means we still have colorful leaves on some of the trees.

It’s not what you look at that matters, it’s what you see. ~Henry David Thoreau

1. Freezing Fog Morning

Last Saturday was a beautiful sunny day with temperatures in the 50s F. Sunday, the weather people said, would be even better with wall to wall sunshine and temperatures in the 60s. In New Hampshire such predictions for a December day are enough to get people really excited, but unfortunately a fog rolled in overnight and at 10:30 am on Sunday our landscape still looked like the photo above.

2. Frosty Leaf

Not only had fog rolled in but cold as well, so this wasn’t just ordinary fog. No, this was freezing fog.

3. Frosted Twigs

Everything was coated in rime including the roads if you could believe the road watchers. I didn’t happen to see any icy roads but maybe I was just lucky.

4. Foggy View

I had planned the night before to show you a June day in December with sunshine, blue skies, and green grass, so I had to come up with a plan B. If there’s one thing you learn as a nature blogger it’s that you have to be flexible and take what nature gives. Make all the plans you want, but nature will do as nature pleases and you’ll either go along or be left out of the game. Anyhow, in a pinch I thought I’d climb one of our many hills to see if I could get above the fog. When I reached the bottom of Hewe’s Hill in Swanzey I was presented with the view in the photo above.

5. Frosted White Pine

This white pine (Pinus strobus) at the trail head really was white, but with frost.

6. Trail

The trail was wet but easily climbed. This is a quick, easy climb and that’s why I chose it. I was afraid the sun would come out and burn off all the mist before I could get up above it, which is exactly what happened when I tried this last year on Mount Caesar in Swanzey. It’s a bit of a letdown to climb as fast as you can only to finally reach the summit and huff and puff as you watch the last wisps of mist disappear before you can even turn your camera on.

7. Spider Web

I didn’t expect to see any spider webs because I thought any sensible spider would be doing whatever spiders do in the winter like maybe sleeping, but there were spider webs to be seen. They looked more like someone’s kite string had tangled in the bushes than the beautiful crotchet like spider webs you’d see in the corners of the Addams Family mansion but there they were; strings of ice.

8. Tree Skirt Moss

The trees wore long stockings made of tree skirt moss (Anomodon attenuates.)

9. Turkey Tail

Blue turkey tail fungi (Trametes versicolor) decorated the logs and fallen branches.

10. Sun Patch

A slice of bright sunlight made me think that I had spent too much time dilly dallying along the trail and had once again lost my chance to get above the fog.

11. Sunshine

In fact my chances weren’t looking at all promising. The mist I saw from the top of Mount Caesar last year burned off quicker than I ever would have believed it could.

12. First Glimpse

But finally there it was, and this was the first glimpse. I had made it, but only just in time.

13. Mist

Is this what a forest fire looks like from above, I wondered?

14. Mist

The cloud was beautiful as it washed through the valley like a stream but silently, without even so much as a sigh.

15. The Edge

Careful, we don’t want to take the fast way down. It would most certainly be our last step.

16. Toadskin Lichen

I visited with my friends the toad skin lichens (Lasallia papulosa) while watching the mist roll on. They’re very shy and only grow on hilltops, but since I always lean on their rock when I come here I’ve gotten to know them well. They were being woken by the first rays of the sun and that made me wonder how much light a lichen needs. I know that they produce their own food through photosynthesis but beyond that I know very little about their light requirements.  I think this one is one of the most unusual and beautiful of our lichens.

17. Mist Breaking

All too soon the mist started to yield to the power of the sun and evaporate.

18. Mist Gone

And then it was gone, just like that, with nothing left but a soft haze, and I sat beside the toad skin lichens wondering about all of the people who had missed it. I wondered if they knew how peaceful it was up here, and I wondered how many knew that most of their troubles and fears would vanish like the mist had if they just spent more of their time in places like this one.

19. Smiley

I knew how the person who blazed the trees must have felt when he or she painted this smiley face because I had smiled myself all the way down the trail. And who wouldn’t, after such an interesting and beautiful morning?

20. After the Climb

This is the same view that appears in the 4th photo in this post just two hours later, so I am able to show you a June day in December with sunshine, blue skies, and green grass after all.
