Posts Tagged ‘Stairtsep Moss’

Last Sunday it was a warm but cloudy day when I went to the Beaver Brook Natural Area in Keene. I haven’t been there to do a blog post since last fall so it was time for another visit. Posts from there usually write themselves as this one did. In fact I often feel like I’m being led from one thing to another; as if there is a director off in the woods saying okay, bring him over here next, and there I find another fascinating bit of nature to show all of you. It really is amazing the way it works but I know I’m not the only one it happens to. Stories write themselves in many minds but whether or not they all include lichens, mosses, and liverworts I don’t know.

This old road was abandoned sometime around 1970 when the new highway was built but strangely, nobody I’ve talked to has been able to remember exactly when. I’m sure there must be records somewhere. As this photo shows, even though the old road is snow covered you can still see that you’re on a road by the old guard posts. Most have rotted away or been broken but in this stretch they look as if they might still keep a car out of the brook.

This post had moss capping it.

The moss on the post was one of my favorites, delicate fern moss (Thuidium delicatulum,) which isn’t really delicate at all but it is very pretty with its fern like foliage.

If you picture a steep sided, V shaped canyon with a stream running through it you’ll have a good idea of what this place looks like. In the 1700s a road was cut through beside the stream and at one time this road carried quite a lot of traffic north out of Keene.

Beaver brook was frozen over for the most part and its normally happy giggles had been hushed down to almost a whisper.

The ice on the brook looked to be about 4-5 feet thick, and that’s because of the water rising and falling so often. Sometimes you come here and the water roars through the canyon, filling the stream banks, and at other times it’s tame, with low water flowing lazily along. If we get the warm temperatures predicted for next week it will be roaring again soon.

If you’ve ever wondered how trees get damaged in the woods, this is one way.

The tree with ice against it is in the previous photo is a golden birch (Betula alleghaniensis.) There are many of them here and they’re easily identified by their color and by the way their bark peels in shreds. These trees like it cool and moist and are often found near streams and ponds. They can also stand a lot of shade so a cool, shaded forest is perfect for them. Golden birch is also called yellow birch, and Native Americans tapped this and other birch trees for their sap, which they boiled down into syrup. They also made a medicinal tea from the bark.

Many of the golden birches here have healed frost cracks, which is that vertical bulge running up the center of this tree. Frost cracks happen when the sun warms the tree and its cells just under the bark expand. If nighttime temperatures are cold enough the bark will cool and contract rapidly, quicker than the wood underneath, and this stress on the bark can cause it to crack.  It’s fairly common to hear trees cracking with a sound like a rifle shot on cold nights.

Stair step moss (Hylocomium splendens) is rare in my experience; this is the only place I’ve ever seen it and I’ve never seen it with new shoots growing, like this example had. The shoots are the tiny white pointed bits seen here and there. This moss was very dry; as dry as paper, so it looks a bit ragged. Normally it is a beautiful healthy green color that sparkles in the right light, and that might be what gives it the name glittering wood moss. It is said to be more common in northern forests and grows even into the Arctic.

Here is a closer look at the tip of one of those shoots.

This is one of thousands of common script lichens (Graphis scripta) that grow on the trees here. The black squiggles that sometimes resemble a long forgotten ancient text are its apothecia where its spores are produced. This family of lichens, like many others, seems to prefer winter to produce spores. Its long, narrow apothecia are called lirellae, and they’ll fade and all but disappear in warm weather. Script lichen is also called secret writing lichen.

An elderly lady passed me on snow shoes and remarked about how beautiful the place and the day were. I agreed, and I wondered if I’d be anywhere near as able as she when I reached her age. She must have been close to 80 but she was cruising right along.

Hobblebush (Viburnum lantanoides) buds are naked, meaning they have no bud scales to protect the bud from the winter cold. Instead they have hair and this one looked very hairy. This native shrub will bloom in mid-May and will be covered with large, hand size clusters of pure white blossoms. The name hobblebush comes from the way it can “hobble” a horse (or a man) with its low, ground hugging tangle of branches. The Native American Algonquin tribe rubbed the mashed leaves of this shrub on their foreheads to treat migraines. They also ate its deep purple berries that appear in fall.

I got to see the chubby purple and green buds of the red elderberry (Sambucus racemosa) that I enjoy seeing so much. They looked a bit dry but they’re on their way to opening I think. It looks as if the outer bud scales have pulled away from the buds. This is another native shrub that has clusters of bright red berries in summer that Native Americans used as food.

There are many ledges here along the old road and last year one of them collapsed into quite a large rockslide, with stones big enough to crush a car falling into the old road.

This shows the big hole in the ledge that the stones left when they fell. Someone small could sit in there behind the ice but I wouldn’t advise it because this area looks very unstable.

Most of the stone in these ledges is feldspar but there is some granite schist mixed in, as can be seen here. There are lots of garnets mixed into the stone as well and though some can be large none are of gem quality, from what I saw in my mineral collecting days.

With a last look at the beautiful blue ice on the ledges I walked back down the old road, in truth wishing I was seeing blue flowers instead. It looks like the end of the really cold air is finally in sight; we’re supposed to see temperatures in the 40s F. next week. That should finally get spring started in earnest.

Winter lies too long in country towns; hangs on until it is stale and shabby, old and sullen. ~Willa Cather
