Posts Tagged ‘Red Bark Phenomenon’

A cute little red squirrel ran up the backside of a pine tree and peeked around it to see what I was doing. I probably see one red squirrel for every hundred gray squirrels so they aren’t that common in this immediate area. They’re cute but if they get into your house they can and will cause a lot of damage. I worked for a lady once who had them in her attic and I spent all summer trapping and relocating them. They had chewed all the wiring, got into stored items, and made a mess in general. A big mess.

I’ve mentioned the storm that dropped 16 inches of snow in other posts but what I haven’t mentioned is the below zero cold that came after. Ponds and streams froze quickly, but as I write this it’s near 60 degrees F. and raining like it was June, so I’d guess tomorrow all the snow will be gone and all the rivers and streams will be at bank-full.

I saw ice doing strange things. I’m sure the wind had a lot to do with this teardrop shape on a standing shrub but I couldn’t quite figure out where the water had come from. Maybe it had simply trickled down the branch but if so why didn’t the wind blow it while it trickled? It seemed to have all collected in this one spot.

Though it’s hard to tell from this photo this is ice, frozen onto deck boards in very strange patterns. I can’t even guess why water would have pooled and frozen in this way, but it was pretty.

Just as I got to work one morning the sun was just kissing the clouds, and I had to stop and watch. I try not to let such things go unappreciated. If you let yourself pay attention to the beauty in this world more and more you’ll find yourself saying a silent thank you. Serenity, gratitude, joy; these are just some of the things that nature will fill you with.

Just to the right of that last shot the sun was also kissing the moon.

Quite often you’ll find a place where the ground looks like it has heaved up and around stones. The stone sits at the bottom of a hole that is usually shaped exactly like it is, so it also looks like the sun has heated the stone enough for it to melt down into the frozen soil. I’ve doubted for years that that is the answer though because the sun would heat the surrounding stones as well and they don’t always melt into the soil. As I walked in this area around the stone the soil sank about two inches with every step, so now I’m certain that frost had heaved up and lifted all the soil and smaller stones that surrounded the bigger one. Frozen soil is a lot more plastic than we realize.

I was happy to see some tiny bird’s nest fungi, which few people ever get to see. I think they were fluted bird’s nest fungi (Cyathus striatus) and this is a view of them from the side. They grow in a funnel or vase shape and have flutes around the rim of the body, which is hollow like a cup. They are so small not even a pea would fit inside them.

The “bird’s nest” is actually a splash cup called a peridium and when a drop of rain falls into it with enough force the “eggs” are splashed out. These eggs, which can be seen here, are really spore cases called peridioles. Once ejected from the splash cup the peridioles degrade over time to release the spores.

There is a much studied phenomenon called the Red Bark Phenomenon, and scientists have devoted much time studying trees with colored bark all over New England. It isn’t always red; it can be orange and yellow as well. It affects all kinds of trees, both conifers and deciduous, and many different species. I’ve seen it here and there on tree bark and after a lot of research a few years ago I found that it was caused by the algae Trentepohlia, which is a genus of filamentous chlorophyte green algae in the family Trentepohliaceae. It appears on tree trunks, stones and is even present in many lichens. So if you see a tree with red bark there isn’t anything wrong. It’s just algae looking for a place to perch. This example was on an eastern hemlock.

Eastern hemlocks (Tsuga canadensis) are numerous here and black capped chickadees flock here to eat the seeds from the hemlock cones like the one pictured above. The 1/2 inch long cones are among the smallest of all the trees in the pine family but the trees usually produce so many of them that the ground is completely covered by them in the spring. The needles and twigs of hemlocks are ground and distilled and the oil is used in ointments. Native Americans also showed Europeans how to prevent scurvy by making tea from the tree’s needles.

Gray birch (Betula alba var. populifolia) flowers grow in long clusters known as catkins. They flower, which means the male flowers release pollen and the female flowers accept it, in April and May and then the female flowers ripen into seeds throughout the summer. Ripe female catkins like the one seen here are called strobiles and resemble small cones. Fruit (seeds) are blown about by the wind in late fall and winter. Unless that is, birds get to them. Many songbirds love them.

You can often find the snow under a gray birch littered with hundreds of tiny winged seeds, which are called nutlets. Seeds can persist for years in the soil and will grow if the soil is disturbed.

Other plentiful winter seeds for birds include those of asters, which I’m still seeing a lot of.

A beech leaf was caught by the sun and was beautiful enough to stop me in my tracks. Beech is a tree that lends great beauty to the forest all year long. Its orangey brown leaves will slowly lighten to a yellow so pale it is almost white, and then they will finally fall to make room for new leaves in spring.

The deep blue shadows on snow always remind me of a special high school art teacher who taught me to see rather than just look. To me, probably due to colorblindness, winter shadows looked gray but she convinced me that they were and should be blue. The odd thing about all of that is how, once I began painting them blue I began seeing them in blue and I have ever since, so she gave me a great gift. Colorblindness is a very strange thing and it doesn’t behave as many people think it does. I can see red and green separately for instance but when a red cardinal lands in a green tree it completely disappears. In fact I have never been able to see a cardinal, even when someone pointed at one and said “It’s right there, can’t you see it?”

But blue still isn’t always blue to these colorblind eyes. I know that cold will turn the normally amber sap of the white pine tree blue but this looks kind of pinky / lavender to me. My color finding software tells me it is steel blue though, and it always wins the argument. Colors come in shades or hues and telling them apart can be quite confusing to the colorblind.

Here is something I’ve never seen before; pixie cup lichens (Cladonia pyxidata) growing on a tree. I know lichens can and will grow on just about anything but until now I’ve only seen this particular one on soil and very rotten wood; never on a live, growing tree. Lichens surprise me continuously. Pixie cups are squamulose lichens, and the tiny golf tee shapes arise from leafy growths called squamules. A squamule is a lobe of the body of the lichen (thallus), and  squamulose lichens have small, leafy lobes, which is the green growth seen here. But though pixie cup lichens are squamulose they have fruticose fruiting structures called podetia. The parts that look like tiny golf tees are its podetia. “Podetia” describes a stalk like growth which bears the apothecia, or fruiting bodies. 

This is the first time I’ve shown the seed pods of the beautiful native shrub known as rhodora (Rhododendron canadense). I’m going to have to watch and see when they open. Quite late, apparently.

I thought I’d show the beautiful flowers of the rhodora because I don’t think most people ever see them. Even in this area it’s a shrub that many don’t know. The flowers appear just when the irises start to bloom and I often have to search for them because they aren’t common. Rhodora is a small, knee high, native rhododendron (actually an azalea) that loves swampy places. It is native to the northeastern U.S. and Canada and both its western and southern limits are reached in Pennsylvania. The flowers appear before the leaves, but only for a short time in spring. By mid-June they will have all vanished.

Sweet gale (Myrica gale) is also called bog rosemary. It likes to grow on the banks of acidic lakes, bogs and streams just like the rhodora we saw previously. Touching the foliage releases a sweet, pleasant scent from its resinous leaves which have been used for centuries as a natural insect repellent. Though it is a native plant here it also grows native in Europe, where it is used as an ingredient in beer making in some countries. It is also used in an ointment used to treat sensitive skin and acne. Its buds are very pretty, but also very small.  They will open and flower in spring.

Is it too early to think of spring? It’s never too early in my opinion and it’s usually in the depths of winter that I start checking buds. These lilac buds were quite pretty, I thought. They are great examples of imbricate buds, which have scales that overlap like shingles. A gummy resin fills the spaces between the scales and makes the bud waterproof. If water got in and froze it would destroy the future flower or leaf embryo within, so buds go to great lengths to prevent that.

While I’ve been working on this post we’ve had just about every kind of weather imaginable. We had snow but of course since it’s so dark before and after work I really couldn’t show it to you. Then on Christmas eve through Christmas day we had temperatures near 60 degrees and 2 inches of rain fell. The shot above shows what the Ashuelot River looks like after 2 inches of rain and a 16 inch snow melt find their way into it. It will boil like this for a few days and then return to its placid self, but meanwhile it will have the wild, rugged beauty we see here. I love watching the waves.

Those who find beauty in all of nature will find themselves at one with the secrets of life itself. ~L. Wolfe Gilbert

Thanks for coming by. I hope everyone will have a happy and healthy 2021.

Last Sunday was a beautiful but chilly day at about 30 degrees F. After almost two weeks of cold weather I thought I’d visit a local beaver swamp to see how they were doing. If beavers haven’t stored enough food underwater before their ponds freeze they can be in serious trouble, and this year the ponds have frozen earlier than average.

What might look like water is actually ice; very smooth ice, but also thin. I walked out on it and didn’t get too  far before it started creaking and cracking, so I quickly returned to shore.

There is a trail of sorts that leads a little way around the swamp. There were lots of fallen trees out here but they were caused by wind and old age, not beavers.

This one broke off about 10 feet up, making it a challenge for a chainsaw. Widow makers they call these, and for good reason.

Stone walls tell me someone used to live out here and farm this land before the beavers took it over. Nobody did the back breaking labor of clearing stones from the land unless it was absolutely necessary, so this wall wasn’t built here for the fun of it. I’m guessing it probably dates from the late 1700s to early 1800s. Many farmers went off to work in factories in the mid-1800s after the industrial revolution and gave up farming, and their pastures slowly returned to forest.

Vinca (Vinca minor) is one of the plants you often find near old stone walls and cellar holes. Others are wild roses, lilacs and peonies. All were passed from one neighbor to another. This colony is one of the largest stands of vinca I’ve seen and it still grows and blooms beautifully after hundreds of years. The word vinca means “to bind” in Latin, and that’s what the plant’s wiry stems do.

I was going to say that there wasn’t a cloud in the sky but there was one shy one hiding behind some trees.

Not all the water here was frozen. This is a seep, which happens when ground water reaches the surface. They are like puddles that never dry up and they don’t flow like a stream or brook. In my experience they don’t freeze either, even in the coldest weather. They are always good to look at closely, because many unusual aquatic fungi like eyelash fungi and swamp candles call them home. They’re also an important water source for many small animals and birds.

Stilted trees grow from seeds that fall on a rotted log or stump and grow their roots around the stump or log. Once the stump or log rots away what is left is a tree that looks like it’s standing on stilts. The strange thing about this stilted tree though, is how it grew over a stone. I don’t see them do that very often. I’m guessing that, probably over centuries, enough leaves fell on that stone to eventually turn into humus. Enough at least for a tree seed to sprout.

This is more what I’d expect from a stilted tree. Whatever it grew on has rotted into the soil and now it looks like it’s running away.

This beaver pond has two beaver lodges in it and this is one of them. I don’t know if that means there are two families of beavers or if one family uses both lodges. Beavers will move into a place, dam a stream to make a pond, and cut all the nearby trees and then move on. Their pond will eventually drain and new trees will start to grow, and then they will move back again to repeat the cycle. I’ve read that it takes about thirty years to go once around the cycle. I’m not sure what stage of the cycle this pond is in but I’ve never seen freshly cut trees here.

There are lots of standing deadwood here and that usually means it’s a good place for great blue herons to nest. I’ve seen the big birds fishing here but I’ve never seen one of their huge nests in any of the trees. What struck me most about this place was the quiet. I heard a bird or two but for the most part it was absolutely still, and that’s a rare and wonderful thing.

Here was a sign of beavers. I think that dark line of ice was made by beavers trying to keep their channel from freezing. But freeze it did, later than the rest of the pond, and that means thinner, darker ice.

Much of the ice was made up of large crystals.

Leaves were frozen into the ice in places and they were white with rime.

Scratches on a tree were too small for a bear. I’d guess it was a bobcat because I found wild turkey wings very close to this spot one day. Bobcats are one of the most common predators of wild turkeys. According to the New Hampshire Department of Fish and Game “Based on observation reports occurring over the previous 20 years, bobcat numbers appear to have increased in New Hampshire. They  take advantage of environmental conditions, such as winter snow depth, to kill large prey, such as deer and turkey.”

Seeing green goldthread leaves was enough to have me longing for spring, even though winter hasn’t yet arrived. Goldthread (Coptis trifolia) gets its common name from its bright yellow, thread like roots. Native Americans showed early colonists how to chew the roots to relieve the pain of canker sores and that led to the plant being called canker root. It became such a popular medicine that the Shakers were paying 37 cents per pound for dried roots in 1785 and people dug up all they could find. At one time more goldthread was sold in Boston than any other plant, and of course that meant the plant came close to being lost. Two centuries of being left alone have brought healing to Goldthread though, and today I see the tiny but beautiful white flowers quite regularly in April.

Many mosses will grow on wood, stone or soil and delicate fern moss (Thuidium delicatulum) is one of them. Delicate fern moss is a beautiful little thing that isn’t as delicate as its name implies, but it certainly is fern like. The leaves of this moss are often bright yellow green in fall and are dull rather than shiny. It is fairly common and easy to find because it often forms very large mats. It grew on many of the logs here.

American wintergreen (Gaultheria procumbens,) is also called teaberry or checkerberry and it is the first wild plant that I learned to identify, with the help of my grandmother. We used to love to eat the bright red minty tasting berries. It’s probably the easiest of all wintergreens to identify because of the strong, minty scent that comes from its crushed leaves. If you have ever tasted teaberry gum then you know exactly what it smells and tastes like. The plant contains compounds that are very similar to those found in aspirin and Native Americans used it much like we use aspirin. Its leaves often turn purple as the nights get colder, as these plants show. The name teaberry comes from a pleasing tea that can be made from the leaves. Squirrels, chipmunks, mice, grouse, partridges, bobwhites, turkeys, fox, deer and bears eat the berries.

There is a much studied phenomenon called the Red Bark Phenomenon, and scientists have devoted much time studying trees with colored bark all over New England. It isn’t always red; it can be orange as well. It affects all kinds of trees, both conifers and deciduous, and many different species. I’ve seen it here and there on tree bark and after a lot of research a few years ago I found that it was caused by the algae Trentepohlia, which is a genus of filamentous chlorophyte green algae in the family Trentepohliaceae It appears on tree trunks, stones and is even present in many lichens. So if you see a tree with red bark there isn’t anything wrong. It’s just algae looking for a place to perch.

Hope and the future for me are not in lawns and cultivated fields, not in towns and cities, but in the impervious and quaking swamps. ~Henry David Thoreau
