Posts Tagged ‘Married Trees’

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

It has gotten cold enough now to start freezing up our ponds and rivers.  I’ve seen pancake ice on rivers many times and I’d expect to see it there; it’s the current that constantly moves circles of river foam or slush and makes them bump into each other and form rims, so that they start to look like pancakes. Most are about the size of a honeydew melon but they can be bigger or smaller. From what I’ve read pancake ice is rare outside of the arctic but I see it on the Ashuelot River almost every winter. What is strange about the ice pancakes in the above photo is that they were in a pond, not a river. Normally there is no current in a pond but we had very strong winds and I think they were what made the current that formed the ice pancakes.

In this photo you can see the ice ridge caused by the wind blowing across the pond. It blew all the slushy ice that had formed on part of the pond to this end and then spun some of it into pancakes.

On shore the ice kept piling up into higher ridges. In the arctic these frozen “pancakes” can pile on top of one another and in some areas 60 foot thick ridges of them have formed. In two days after it warmed up a little all of this ice had disappeared.

A milkweed seed was stuck on a very hairy branch of an American hazelnut (Corylus americana.) A good way to tell that you have an American hazelnut and not its cousin the beaked hazelnut is by the very hairy stem seen here. Only American hazelnut has hairy stems.

The male catkins of an American hazelnut are bigger in diameter and longer than those of the beaked hazelnut, from what I’ve seen. In spring they’ll slowly grow even bigger until finally turning golden yellow and bursting with pollen. I wait impatiently for it to happen.

If the male hazelnut pollen reaches a female ovary then there’s a good chance that hazelnuts like those seen here will be the result. In 1995 a large shallow pit in Scotland was found to be full of the remains of thousands of burned hazelnut shells and was estimated to be 9,000 years old, so man has been eating this nut for a very long time. In this country Native Americans used them to flavor soups, and also ground them into flour, most likely for thousands of years as well.

Here is a common sight in winter: milk white toothed polypore (Irpex lacteus) is a resupinate fungus, which means it looks like it grows upside down, and that’s what many crust fungi appear to do. This is a very common winter fungus that grows on the undersides of limbs. The “teeth” are actually ragged bits of spore producing tissue which start life as pores or tubes and then break apart and turn brown as they age.

If you pick up a fallen limb and touch something that feels cold and rubbery, it might be milk white, toothed polypore. They are very tough and can stand all the snow and cold that winter can throw at them. I’ve never seen the interesting patterns that this one displayed.

If two trees or parts of trees like limbs of the same species grow close enough together the wind can make them rub against each other, wearing the outer bark away. Once the outer bark wears away and the cambium or inner bark touches, the trees can become naturally grafted together. The process is called inosculation and isn’t as rare as we might think. I see at least a couple of self or naturally grafted trees each year.

If you thought you saw scratches on the bark of the maples in the previous photo you weren’t imagining it. Squirrels leave claw marks all over smooth barked trees and sometimes if you look closely you can see trails up the tree that they use over and over again. On those kinds of trails the scratches will appear thickly like those in the photo. I’ve known for a longtime that squirrels will nip off buds to make tree branches easier to travel on, but this is another of those bits of nature that I have never understood until just recently.

The beautiful color of a maple branch healing itself held me rapt for a time, and I remembered all of the times I’ve felt down when I walked into a forest, only to return having forgotten what it was that bothered me. The forest is such a loving place; a place full of miracles and one that reveals the secrets of creation, and it pains me to know that some people think it is a dark, forbidding place to be feared. Given a chance it will change you, and even heal you. If you spend enough time there first will come joy, and then a deep sense of gratitude and finally, after a time that might be weeks, months, or even years, a great love will well up inside of you. It is the love of all things; of creation, and at times it is so powerful it can bring tears to your eyes and make you want to kneel; not because someone tells you should but because of the love, gratitude and joy that you feel inside. You’ll begin to understand that you aren’t separate from all of this and you never have been. You are as much a part of nature as the birds that sing overhead and the leaf mold you might one day find yourself kneeling on.

Wild cucumber (Echinocystis lobata,) seed pods dry as thin and weightless as a sheet of paper, so though their spines are sharp at this point you can’t throw them at your friends. In the lower right quadrant of this example you can see a bit of the netting that is inside these seed pods. A man wrote to me once and told me that he decorated pens that he makes with that same netting. For me these plants are like a time machine that always takes me back to my boyhood, when we used to throw the soft spined fruits at each other before they dried out.

Wild cucumbers have two large seeds that look like cucumber seeds but they’re at least 10 times bigger. The cavities seen here are where they grew. I’m seeing fewer and fewer of these vines each year and I can’t understand why. When I was a boy they were everywhere but now I have to search, often for days or even weeks, to find them.

Last year I saw a very strange pouch like cocoon on a tree. It wasn’t very big; about the diameter of a pencil or maybe a little bigger. I hadn’t ever seen anything like it and couldn’t find anything that looked like it online so I wrote to a local insect expert who explained that it was a tussock moth cocoon, probably made by the white marked tussock moth. The caterpillar constructed it incorporating its own hairs into the design. Now here was another one, almost exactly a year later.

All of the gypsy moth egg cases I’ve seen have been smooth and hard, like this one. European gypsy moths were first brought to the U.S. in 1869 from Europe to start a silkworm business but they escaped and have been in the wild ever since. In the 1970s and 80s gypsy moth outbreaks caused many millions of dollars of damage across the northeast by defoliating and killing huge swaths of forest. I remember seeing, in just about every yard, black stripes of tar painted around tree trunks or silvery strips of aluminum foil wrapped around trunks. The theory was that when the caterpillars crawled up the trunk of a tree to feed they would either get stuck in the tar or slip on the aluminum foil and fall back to the ground. Today, decades later, you can still see the black stripes of tar around some trees. Another gypsy moth population explosion happened in Massachusetts recently and that’s why foresters say that gypsy moth egg cases should be destroyed whenever they’re found.

This little moth was on the door of the maintenance shop where I work one morning and it stayed there all day. Since it was about 30 degrees that day I thought it was odd behavior, but then I looked it up and found its name is the Winter Moth. It is a European species that was first noticed in Nova Scotia in the 1930s and now is found coast to coast in the U.S. It’s a very destructive insect, especially to apple and blueberry crops because its caterpillars eat the emerging buds in spring just as the bud scales open. They also feed on maple, oak, ash, crabapple, cherry, and many deciduous shrubs. According to the University of Massachusetts “The eggs are green at first, but turn red-orange soon thereafter. In March, prior to hatching, the eggs turn a bright blue and then a very dark blue-black just before hatching.” They sound very pretty but I think I’d rather not find any.  

Smooth sumac (Rhus glabra) berries are ripe and red. These berries don’t get anywhere near as hairy as staghorn sumac berries do but the plants still look alike and are easy to confuse if you don’t look closely for the hairy stems of staghorn sumac. Smooth sumac leaves turn bright red in the fall and produce a rich brown dye. Birds supposedly love them but the berries are usually still there in spring until the migratory birds come through.

Staghorn sumac berries, like the rest of the plant, are very hairy. They are said to be an important winter emergency food for many types of birds including Robins, Evening Grosbeaks, Bluebirds, Cardinals, and Scarlet Tanagers in other parts of the country but like the smooth sumac berries seen in the previous photos, staghorn sumac berries aren’t usually eaten until spring here. That could be because we have so many other native fruits and berries for them to eat. After a thorough soaking and washing, the berries were made into a drink resembling pink lemonade by Native Americans. In the Middle East they are dried and ground into a lemon flavored spice.

Even on a cloudy day the stems of staghorn sumac glow, and they really do resemble deer antlers. (Antlers are not horns, by the way, and a stag has antlers.) If this were a smooth sumac this branch would be as smooth as a maple branch.

Many things in nature will turn blue when it gets cold enough. Ice can be blue and so can the sap of the white pine tree. I’ve also seen the white striations that give striped maple (Acer pensylvanicum) its name turn blue. This is the only maple tree in New England that has bark that is striped like this. Other names for the tree are snake bark maple, moosewood maple, goosefoot maple, Pennsylvania maple, and whistle wood, because the soft pith makes the wood easy to hollow out and make whistles from. Native Americans used the bark of the tree to treat many ailments including coughs and colds.

I like the flowers of thimbleweed but I never see many of them. Until recently, anyway; I stumbled into a forest of them and for the first time, saw them going to seed. The plant gets its name from the seed head that grows to look like a thimble and I’ve seen those, but until now I’ve never seen one actually producing seed. The seeds are on the sticky side and before I was through trying to get a photo I was covered with them, so I might find them growing in my own yard one day.  

Here is a beautiful turkey tail fungus (Trametes versicolor) for your Thanksgiving. If you walk off that big meal on a wooded trail you might see some in person. They’ll be far more beautiful there than they are here.

I thought I’d end this post with one of the things I’m thankful for; this view of Mount Monadnock I see every morning on my way to work. If you click on it you’ll see a larger version and then you might be able to see the snow on the summit.

If you see no reason for giving thanks, the fault lies only in yourself. ~Tecumseh, Shawnee

I hope all of you have a safe and happy Thanksgiving day. Thanks for coming by.
