Posts Tagged ‘Woodpecker Damage’

I think it had been a year or more since I had climbed the High Blue trail in Walpole so last Saturday that’s where I went. It’s more of a walk than a climb but still, it’s enough to get someone with tired lungs huffing and puffing. It was another beautiful spring day and there is a lot to see there, so I was looking forward to it.

There are a lot of ruts in the old logging road that starts the climb and many of them still had rain water in them. Salamanders took advantage of the small ponds, swimming in them as these two did. New Hampshire has eight native salamanders including the red-spotted newt, and I think that’s what these were. The larva are aquatic and so are the adults, but the juveniles are called red efts and live on land.  They eat just about anything that is small enough, including earthworms and insects. As I walked on I heard the quacking of wood frogs and the trilling of spring peepers, so there is a lot of water in the area.

Coltsfoot plants (Tussilago farfara) were blooming by the dozens.

Striped maple buds (Acer pensylvanicum) are getting bigger each time I see them. They’ll be opening soon.

Hobblebush buds (Viburnum lantanoides) are going to bloom early this year, I think. Normally they wouldn’t open until May but these warm days are accelerating everything.

The early warmth has wreaked havoc on the maple syrup industry. The last article I read said one of the larger local producers was down more than 10,000 gallons below average. This shot shows how most of the big producers collect sap these days; with food grade plastic tubing.

It’s very simple really. The tapper drills a hole in the tree and the black piece seen above is inserted into the hole. The syrup flows through the blue tubing to the green tubing and from there to the collection tanks. Vacuum pumps are sometimes used to pull the sap through the tubing.

It’s nearly impossible to get lost up here with signs like these directing you.

It isn’t far to the summit but as slow as I walk, it takes a little while. I walk slow purposely as I’ve said many times before. Adopt a toddler’s pace and then you begin to see all the things in nature that you’ve been rushing past all these years.

Black knot grew on a young cherry tree. Infected stems swell up and produce hard black knots like those seen here. They will eventually become serious wounds and will 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.

Woodpeckers had been gouging out the wood of a dead birch.

This pile of shavings at the base of the tree showed that they had been working hard.

I saw that they were still growing corn here. When I first started hiking here this was a meadow full of wildflowers including orange hawkweed, which is hard to find.

I always wonder who gets the most corn, the farmer of the animals. I think that bears eat a lot of it. I’ve followed game trails away from the cornfield and have found whole stalks that have been dragged off. It takes strength to pull up a corn stalk and I doubt deer could do it.

Willows bloomed off in the distance across the cornfield.

Two or three red maples, all male flowered, bloomed along the trail side of the cornfield.

This is very stony ground up here with ledge outcrops like this one fairly common. I’ve always thought of features like these the bones of the forest.

This outcrop was mostly quartz and rock tripe lichen grew all over it. Rock tripe lichen (Umbilicaria mammulata) gets brownish and curls up when it is dry like these were. You can see the back of it , which is black and pebble textured in this photo. The Umbilicaria part of the scientific name comes from the Latin umbilicus, meaning navel, because of the way they attach themselves to stone with a single attachment point that looks like a navel. It sticks itself to stone by way of this single, navel like attachment point and the rest of the lichen hangs from this central point, much like a rag hanging from a peg. Rock tripe is edible and eating it has saved the lives of people who were lost and starving in the past. Though I imagine they must taste like old rubber, these lichens were a source of emergency food for Native Americans and saved the lives of many an early settler. Even George Washington’s troops are said to have eaten rock tripe to survive the brutal winter at Valley Forge in 1777.

Running club moss (Lycopodium clavatum) is also called stag’s horn clubmoss. This plant gets its name from the way it sends out long, horizontal stems. All along the horizontal stem erect stems form at intervals and roots form where it touches the ground. All of this happens under the leaves so it can be difficult to tell this club moss from others. I can’t say that these plants are rare here, but I don’t see them too often. For you people who have the app, Google lens identifies it as stag’s horn clubmoss.

The remains of an old foundation always make me wonder about the people who once lived up here. It’s easy to forget that just one hundred years ago most of these hills were cleared and used as pasture land. Once the industrial revolution happened people left the farms to work in the mills and ever since the land has been going back to forest.

These people worked hard, whoever they were. This stone wall runs off into the distance as far as the eye can see.

The pond that lives up here already had duckweed growing on it. And it was full of singing frogs.

I’ve seen these what I think are insect egg cases before but I’ve never been able to identify them. If you’ve ever seen a Tic-Tac candy mint, these are the same size and shape that they are. In other words, quite small. Google lens kept trying to identify the shrub instead of them. Apparently it couldn’t see the egg cases.

The sign at the overlook lets you know how high up you are…

…and the view is always blue, hence the name High Blue. The view was a little hazy but I could see the ski trails over on Stratton Mountain in Vermont, which is just across the Connecticut River Valley. I was surprised to see snow on them, because where I was sitting it was about 74 degrees. Far too warm for this early in spring but as anyone who spends much time in nature knows, you have to be at peace with what nature gives.

I didn’t realize, until I started cleaning it up, how much stuff falls from trees. There must be tons of it raining down; it falls 24 hours per day seven days per week. Eastern forest broadleaf trees alone, it is estimated, can drop 2 to 3 tons of leaves per acre in the fall. And then there are the branches, seed cones, acorns and everything else that falls. If it wasn’t for the animals, bacteria and fungi that process it we would surely be buried under it all.

The tiny black specks you see here are seeds of the gray birch (Betula populifolia). Tiny yes, but there must have been millions of them in this small birch grove. Pine siskins, chickadees, and other songbirds eat them. Deer, moose and rabbits eat gray birch twigs.

I thought the brown on the snow in this shot must be dust like seeds but I suspect it was just dust.

Eastern white pines (Pinus strobus) drop an incredible amount of material each year; large branches, needles, cones and bark all end up on the forest floor.

Whenever I see a fallen pine branch I check it for lichens and probably 8 out of 10 times there are lichens on it. I believe this foliose example is in the Tuckermanopsis family, possibly Tuckermanopsis americana. It was quite dry even though it was on the snow, so I’d guess that its color had lightened.

After branches pine cones are probably the things that fall out of pine trees the most. They are everywhere, but they don’t always fall end first into the snow like this one had. The heavy end falls first sometimes like this one did but I’ve also seen them turned 180 degrees with the lighter end in the snow.

Usually when you see a fallen pine cone they look like this, but this one has done something special; the sun had heated it enough for it to melt its way into the snow. I’ve seen oak leaves melt into the snow in the same way.

When I see good size fallen pine limbs I always look for bark beetle damage. Bark beetles usually attack weak or dying trees but they can also kill healthy trees by girdling them.  Adults bore small holes in the bark and lay eggs in a cavity. Once the larvae emerge from the eggs they make tunnels in the inner bark, like those seen here. Once they stop feeding they will pupate at the end of these tunnels. The pupae then become young adults and fly off to find another tree. These beetles carry spores of various fungi which can grow on the outer sapwood and stop the upward flow of water to the crown. Bark Beetles include over 100 species and it is said that their work is like a fingerprint for the species. They can create such beautiful patterns in wood that it looks as if a calligrapher has taken up a chisel instead of a pen.

Mosses of course, are also common on fallen branches. These were very dry but the shield lichen next to them didn’t look too bad. I think it was a common greenshield (Flavoparmelia caperata) , which is indeed very common. They often have patches of granular soredia on them as this one did in its center.

If white pine branches are the most common on the forest floor then eastern hemlock (Tsuga canadensis) branches are the second most common. The difference about hemlock branches though, is how they are almost always small enough to decompose quickly.

Both pines and hemlocks catch much of the snow on their branches, and underneath them the ground is often bare or nearly so in all but the snowiest winters. These bare spots are often full of small birds like juncos scratching around for seeds.

Honey locust (Gleditsia triacanthos) seed pods are pretty things. When the seed pods are green the pulp on the inside is edible and very sweet, while the pulp of the very similar black locust (Robinia pseudoacacia) is toxic. One good way to tell the two trees apart is by the length of their seed pods; honey locust pods are much longer and may reach a foot in length, while black locust pods only grow to about 4-5 inches long. Honey locust seed pods look a lot like giant flat string beans about 9-12 inches long and often curled. Some of them look like polished mahogany and others can be purple. Beautiful white, fragrant flowers cover these trees in late spring. Locusts are legumes, in the pea family. Deer love the seed pods, which often fall in such abundance they cover the ground under the trees.

You want to watch where you walk under a honey locust because fallen branches can be very thorny. Honey locust thorns grow singly and can be 3 to 6 inches long. They will sometimes branch like the example in the photo. These thorns are big and as hard as iron. They can reach 6 inches in length and poke right out of the bark of the tree along its branches and sometimes even the main trunk. They are tough enough to puncture shoe soles and can cause a nasty wound. In the past the hard thorns of the younger trees were used as nails. Confederate soldiers once used them to pin their uniforms together and survivalists still use them as fish hooks, spear heads, nails, sewing needles and even small game traps. Native Americans used the wood to make bows, and medicines were made from various parts of the plant.

The orangey color of these leaves caught my eye. I think they may have been American hornbeam leaves (Carpinus caroliniana). This tree is also know n as muscle wood, ironwood, hornbeam and blue beech, and younger trees will often hang onto their leaves quite late into the year.

In the fall shortening day length tells most deciduous trees that it’s time to stop growing, so the tree forms a layer of waxy, corky cells at the base of each leaf. This is called an abscission layer, and it slows and finally stops the flow of sap to the leaf. In some trees like oak (Quercus), beech (Fagus), and hornbeam (Carpinus), this abscission layer forms much later, so even though the leaves might freeze dead and turn completely brown they still cling to the branches. Pin oaks (Quercus palustris) don’t form an abscission layer until spring, so their leaves stay on the tree all winter. This retention of dead leaves is known as marcescence. When I start seeing lots of beech leaves blowing around in late winter I get excited, because that means spring isn’t far off.

I think this pile of beech leaves, blown by the wind, was fairly recent.

I see a lot of woodchips around dead and dying trees, almost always left there by woodpeckers. These small bits of wood disappear quickly.

Trees losing their bark isn’t anything strange but there were a lot of animal tracks around this tree and it looked like an animal might have pulled this piece of bark off. Porcupine maybe?

This white pine had lost some of its bark but it wasn’t lying on the ground anywhere near the tree that I could see. Wounds like this are how fungi can get into a tree and start things like heart rot.

I was surprised to see a virgin’s bower vine (Clematis virginiana) on the ground. This vine can climb high enough to make it into the trees occasionally but usually it just drapes itself over shrubs and hangs on tight. It’s more likely to decompose right there on the shrub than to fall on the forest floor. Those long feathery filaments called styles are on its seeds (fruits) so the wind can carry them, but that can’t happen if they’re on the ground.

This switch grass did most certainly not fall from a tree but its delicate beauty caught my eye so I’ve put it here. I hope you enjoy seeing it as much as I did.

Anyone who thinks fallen leaves are dead has never watched them dancing on a windy day. ~Shira Tamir
