1-naturally-grafted-maples

Since I live in a forest and work in a forest and spend most of my free time in forests, I see a lot of trees. But I don’t see many like these two. If two trees or parts of trees like limbs or roots 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. From what I can tell these two maples had limbs that rubbed together and finally grew together years ago.

2-natural-graft-on-maplws

Trees that are naturally grafted together or conjoined are sometimes called “husband and wife” trees, or “marriage trees.” These two young red maples (Acer rubrum) were in the early stages of becoming grafted; it’s easy to see where they rubbed together. This can happen to most species of trees and can sometimes even happen to two trees of different families, like a red maple and a sugar maple.

Man can also graft trees and has been doing so for as long as anyone can remember. Fruit trees, especially apples, are often grafted. Many other plants like roses and grapes are also grafted onto the stronger rootstock of another in the family.

3-entwined-striped-maples

These young striped maples were entwined but not yet conjoined. Though it looks like there are three trees here there are only two. The ones on the right and left come from one stump and the middle tree comes from a separate stump. Why they grew this way is anyone’s guess but I’d say it’s a fair bet that they will all eventually become one tree. You can see how the bark has puckered on the lower part of the tree on the far right, and that’s a sign that they have been rubbing together.

4-lichens-on-tree

Trees support a lot of life on their limbs and bark, like the many lichens pictured here. Since people see lichens growing on the dead branches of trees they think the lichens killed the branch but lichens simply sit on the bark and take nothing from the tree. They are opportunists that like a lot of sunshine though, and the best place to find the most sunshine is on a branch with no leaves on it.

5-script-lichen

I always like to look at trees like the one in the previous photo because the spots on their bark can turn out to be quite beautiful, like the script lichen pictured here. Script lichen looks just like its name suggests but it is a very ancient script, like long forgotten runes. The dark “script” characters are its fruiting bodies that produce its spores. There are many script lichen species and each seems to prefer a certain species of tree. I think this example is the common script lichen (Graphis scripta) which prefers smooth barked trees like maple and beech.

6-maple-dust-lichen

Other spots on trees might turn out to be beautiful maple dust lichens (Lecanora thysanophora.) I don’t have time to look at every tree with lichens on its bark, but I wish I did because when I don’t look closely I feel as if I’m missing something beautiful.

7-target-canker-on-red-maple

Target canker doesn’t harm the tree but causes its bark to grow in circular patterns of narrow plates which helps protect it from the canker. According to Cornell university: “A fungus invades healthy bark, killing it. During the following growing season, the tree responds with a new layer of bark and undifferentiated wood (callus) to contain the pathogen. However, in the next dormant season the pathogen breaches that barrier and kills additional bark. Over the years, this seasonal alternation of pathogen invasion and host defense response leads to development of a ‘canker’ with concentric ridges of callus tissue—a ‘target canker.’” Apparently the fungal attacker gives up after a while, because as the tree ages the patterns disappear and the tree seems fine.

8-burl-on-maple-2

Burl is an abnormal growth that grows faster than the surrounding tree tissues. Scientists don’t fully understand why it happens but burls are thought to grow on trees that have been weakened by stress or damage.  Once the tree’s defenses have been weakened insects and /or fungi can attack and cause the abnormal growth. Woodworkers make some very beautiful things from burl and prize them highly. I find them more on black cherry than any other tree, but this example was on an old maple. It was as big as a basketball.

9-chaga

Trees of course are very beneficial to mankind in many ways, even medicinally. Chaga fungus (Inonotus obliquus) is a parasitic fungus that grows on birch and other trees. Though many think that the area that looks like burnt charcoal is the fruiting part of the fungus it is actually the “roots” or mycelium. It is black because it contains large amounts of melanin, which is a naturally occurring  dark brown to black pigment in the hair, skin, and iris of the eye in people and animals. It is also responsible for the tanning of skin exposed to sunlight. This fungus has been used medicinally in Russia, China, Korea and Japan for centuries, and it is said to be packed with vitamins and minerals. Recently it has shown promise in cancer research, reducing the size of tumors. In Siberia it is said to be the secret to long life.

10-bootstrap-fungus

Fungal spores entering a wound on a tree can sometimes mean death for the tree. Bootstrap fungus is caused by honey mushrooms (Armillaria mellea), which are parasitic on live wood and send out long root like structures called rhizomorphs between the wood of a tree and its bark. When fresh the rhizomorphs are cream colored but darken to brown or black as they age. The fungus is also called armillaria root rot or shoestring root rot. It causes a white pulpy rot in the wood and kills many species of both soft and hardwood trees.

11-pine-tree-foam

For years I’ve noticed that a soapy foam at the base of certain white pine trees (Pinus strobus) when it rains. Sometimes it is in just a spot or two and at other times it nearly circles the entire tree.  This happens because when there is a drought or dry spell salts, acids and other particles from the air can coat the bark. Soap is essentially made from salts and acids and when it rains, these natural salts and acids mix with the water and begin to froth. The froth (foam) is from the natural agitation of the mixture when it finds its way around bark plates as it flows toward the ground.

12-frost-rib

This hemlock tree had a healed frost crack, called a frost rib. 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.

13-frost-rib

Another example of a frost rib, this time on yellow birch (Betula alleghaniensis.) Frost cracks and frost ribs are fairly common.

14-bittersweet-on-elm

Many things can damage a tree. This oriental bittersweet vine was about the same diameter as my little finger and was already strangling a young elm that was wrist size. Anyone who has ever tried to cut or split elm knows that it’s one of the toughest woods, so the bittersweet must be very tough indeed. It’s hard to know which will win this battle; I’ve seen trees with bittersweet vine grooves in their bark live on, and I’ve seen live bittersweet vines on dead trees.

15-bittersweet-berries-2

Oriental bittersweet is all about continuation of the species, so it climbs up trees so it can sit in the crown and gather up all the sunlight so it can flower well. Each pollinated flower means a berry that a bird will come along and eat, and that’s how it multiplies. The young vines are shade tolerant, so when a bird sits in a tree and drops a seed to the ground beneath it the plant can germinate and live on while searching for the best path to the light at the top of the tree. Other vines like our native Virginia creeper, grapes and virgin’s bower also seek light at the tops of trees but they aren’t nearly as aggressive and don’t hurt them.

16-fence-in-woods

One of the strangest things I’ve seen in the woods recently is this old piece of fence connected to a tree. It has been there so long the tree has started to grow over it and if it continues the tree will eventually has a substantial piece of fencing embedded in its wood for its lifetime. Trees seem to shrug this kind of thing off and just keep on growing, no matter what the obstacle might be. The process is known as “compartmentalization of decay in trees,” where the tree uses scar tissue to compartmentalize the section with a foreign object in it. They do the same thing when fighting decay.

17-fence-grown-into-tree

Though trees might easily shrug things like this off,  woodcutters don’t. There’s nothing worse than running into a piece of metal with a chainsaw. Not only does it ruin the chain, it’s also very dangerous. Many things have been found in trees, including screws and nails, signs, pipes, fencing, cannonballs, bullets, beer bottles, hammers, hand saws, horse shoes, chains, ropes, stones, and one arborist even found a Chevy Corvette rim.  It seems that a tree will grow around just about anything.

18-zig-zag-scar

Sometimes scars on trees aren’t easy to explain. I’ve shown this zig zag scar on this old hemlock a few times on this blog and the consensus seems to be that it was made by lightning, but I wonder if we aren’t thinking that simply because both lightning and the scar are zig zagged. In any event I don’t suppose we’ll ever know for sure but it’s fun to guess at its origin. It comes directly out of the ground, straight for about half its length, then it zig zags for the other half. Its total length is about 4 feet.

19-zig-zag-scar

This is a close look at the zig zag scar in the previous photo. It doesn’t look like it was made by a boy with a new pocket knife either. If you’ve ever seen anything like it or know what might have caused it there are several of us who would love to hear from you.

20-beech

I can’t understand how someone can walk out of a forest and say they didn’t see anything, but I’ve heard people say it a few times. “For gosh sakes,” I always want to ask, “what about the trees!?” You don’t need to know anything about burls or frost cracks or inosculation or even what kind of tree you’re looking at to just enjoy their astounding beauty. That’s what I spend a lot of my time in the woods doing, and I hope you will too. I’ve put this post together with the thought that it might make your next journey through the woods a little more interesting.

I did not want to think about people. I wanted the trees, the scents and colors, the shifting shadows of the wood, which spoke a language I understood. ~ Patricia A. McKillip

1-trail

Each year at this time I start thinking that if I could just get up above the trees the colors would be better or brighter somehow, but they never seem to be and I’ve never been really happy with any photo that I’ve taken that way. But maybe this time would be different, I hoped. The weatherman told me that we were at the peak of our fall colors, so last Saturday I decided to climb Pitcher Mountain in Stoddard to try again.

2-striped-maple-leaf

I kept seeing dark spots on the fading, pale orange striped maple leaves (Acer pensylvanicum) so I had to take a closer look. The quarter size spots were made up of many smaller specks.

3-striped-maple-leaf

I haven’t found a reference to anything similar so I can’t say what they are at this point. They looked like hardened drops of a liquid but I doubt the leaves would weep in such concentrated areas and not all over. If you know what they are I’d love to hear from you.

4-torn-mushrooms

Something ate these little brown mushrooms and tore the stems when they did so. I’ve never seen this before and I’m not sure what animal would do it. There is everything from chipmunks to moose to bears in these woods so without tracks or other clues it’s hard to know. I do know that many kinds of little brown mushrooms can make a person very sick, and some can kill.

5-pasture

A pasture appears on the right side of the trail and I always stop here for a breather. The farm that owns this land raises Scottish highland cattle and my hopes of seeing them were raised by the regular snapping of an electric fence at just about knee and waist level, but the cattle never showed up. I had to pay attention so I didn’t get tangled in that fence with my metal monopod, so maybe it’s a good thing they didn’t.

6-trail

The trail takes a sharp 90 degree left turn and parallels the pasture for a time. It also becomes quite rocky in this stretch. Not far after the turn, maybe a hundred feet or so, there is a break in the trees and brush to the right. If you follow this short path after just a few steps you come to a good view of Mount Monadnock on the right. And the electric fence in front of you.

7-monadnock-from-trail

The reason I chose Pitcher Mountain is because it has a full 360 degrees of viewing area on its summit. If the light is harsh in one direction as it was in this shot of Mount Monadnock from the trail, it often isn’t quite so harsh in a different direction. At least that’s what I was hoping. Finding correct exposure settings can be tough with some colors in such bright light.

8-beech

Beech trees are starting to turn and they seem to be right on schedule. Though they are among the last to turn along with the oaks, most had turned fully by Halloween last year.

9-fire-tower

Before too long the fire tower glimpsed through the trees tells you that you’re very near the summit.

10-ranger-cabin

The old fire warden’s cabin might be in for a rough ride this winter if nature decides to make up the 15 inch rain deficit with snow. Though I’ve climbed up here in the winter several times if that happens I probably won’t be up here to see it.

11-pasture-from-above

You can turn and look back just above the warden’s cabin to see the pasture from above, along with Mount Monadnock in the background. The view from the summit to Monadnock would be almost directly south.

12-fire-tower

The fire tower is the second one to stand on this peak. Ironically the first wooden tower built in 1915 burned in April of 1940 in a fire which destroyed 27,000 acres of forest, including the tower and all of the trees on the summit. It was the most destructive fire in the region’s history. Stout cables keep this one from blowing off the mountain but there is still little to protect it from a large fire.

13-near-hill

If you’re standing where I was in the previous photo looking at the tower and walk around to the left side of it, what I call the near hill seems to be close enough to touch. I don’t know its name or if it even has one.

14-summit-colors

It was hard to pay attention to far off colors when colors like this were so close by on the summit.

15-scattered-rock-posy

Scattered rock posy lichens (Rhizoplaca subdiscrepans) added to the orange colors of fall. I was thinking one day about how we rarely see orange in nature for most of the year but then all of the sudden we are saturated with it in the fall. The orange pad like parts of this lichen are its fruiting bodies (apothecia) and the grayish, brain like part is the body (thallus.)

16-crater-lichen

Black and white crater lichens seemed to stare back at me from the stones. I think they are Diploschistes scruposus, simply called crater lichen after their cup shaped black fruiting bodies (apothecia,) which are surrounded by a stark white or gray body (thallus.) They grow on exposed rock all over the earth, even in the Polar Regions.

17-blueberry

Pitcher Mountain is known for its blueberries, and they turn a beautiful red in the fall. They supply most of the red that can be seen in the near distance in many of these photos.

18-blueberries

There were a surprising amount of berries that the birds and pickers had missed, but they were shriveled.

19-fall-colors

As far as the eye could see the trees were turning. I’m surprised to see how many more deciduous trees than evergreens there are in this photo.

20-unknown-mountain

I’m not sure what the name of the mountain in the distance is but it seemed to be higher than the one I was standing on and it wasn’t Mount Monadnock. It was quite far away but unfortunately I didn’t pay any attention to what direction it was in.

21-birch

This birch tree was almost leafless but its comrades more than made up for its lack of color. It seemed a kind of exclamation point, as if colors like these needed to be emphasized.

22-summit-colors

I think this photo is my personal favorite from that day because it has all of the colors I saw in it. It also shows the incredible beauty that can be found up here.

23-natural-birdbath

It seemed strange to see the natural birdbath full of water in the middle of a drought; it must have rained recently. I’m sure the many birds that I heard are very grateful.

I’m sorry that this post was so photo heavy but our autumn “season” is really very short and we’re lucky if we see three weeks of the kind of colors that I saw on this day, so I went a bit overboard. Though I don’t usually climb strictly for the views on this day that’s what I came for and they were very good, with little haze.

To see what others cannot…
You must climb the mountain.
