Posts Tagged ‘Beaver Brook Natural Area’

It was cloudy but warm last Saturday when I visited the Beaver Brook Natural Area in Keene. This is a nice walk on an old abandoned road that is only 5 minutes from the center of town by car, so quite a few people come here. I was pleased to see that there was little snow here on this day because it usually quickly turns to ice from all the foot traffic. As I said in my last post, it is very strange to drive from here where there is virtually no snow to my job a half hour away in Hancock, where there is plenty.

Beaver Brook was behaving itself despite all the rain and snow we’ve had. The last time I came here I would have been in water up to my neck if I’d been standing in this spot.

I have a lot of old friends here, like this plantain leaved sedge (Carex plantaginea.) This is the only place I’ve ever seen it so when I want to see how it changes as it grows I have to come here. There are also many other one-of-a-kinds I can visit while I’m here.

I like the crepe paper like leaves of this sedge.

The sun finally came out just a few hours later than the weather people said it would, and the golden light falling on the brook was beautiful. I dilly dallied for a while beside this pool, thinking how some might consider coming to such a place a waste of time or an attempt to escape reality, but this is not an escape from reality; it is an immersion in reality, because this is just about as real as it gets. And getting a good dose of reality is never a waste of time.

This is the only place I know of to find the beautiful rose moss (Rhodobryum roseum.) Each rosette of leaves is about the size of an aspirin and looks like a little flower, and that’s where its common name comes from. Rose moss likes limestone and it’s a good indicator of limestone in the soil or stone that it grows on, so it’s a good idea to look around for other lime loving plants if you find it. Many native orchids for instance, also like lime in the soil.

Another moss that I’ve only seen here is the stair-step moss (Hylocomium splendens,) which is also called glittering wood moss  possibly due to its satiny sheen when dry. Though it looks quite fragile I’ve seen it with icicles hanging from it many times, and it grows north even into the Arctic tundra. The stair step part of the name comes from the way new growth “steps up” off the midrib of the previous year’s growth. You can’t see it in this photo but it’s a fun thing to look for if you find this moss.

Unlike the rarer mosses we’ve just seen juniper haircap moss (Polytrichum juniperinum) grows just about everywhere, but that doesn’t mean it is any less interesting than the others.

When young the female spore capsule (Sporangium) of juniper haircap moss is covered by a cap called a calyptra which protects it. You can’t see it in this photo but it is very hairy and this is what gives this moss part of its common name. Eventually as the capsule ages it moves from vertical to a more horizontal position and the calyptra falls off. The spore capsule continues to ripen after the calyptra comes off and when the time is right the beaked end cap or lid called the operculum will fall off and release the spores to the wind. As it ages the spore capsule changes from round to four cornered but not quite square, as seen here.

This is a look at the business end of the spore capsule, which is still covered by a thin lid of tissue. What looks like notches around its perimeter are slots that fit over specialized teeth called peristome teeth at the mouth of the capsule. These teeth move with changes in humidity and spread in dry conditions to release the spores, which are taken by the wind. The spore capsule’s diameter at this stage is less than the diameter of a piece of uncooked spaghetti. I’d bet that I’ve probably tried a thousand times over the years to get this shot and this is the only time I’ve succeeded.  I wish I had a microscope so I could get even closer.

Here was another moss that grew all mixed in with a liverwort. It was hard to tell exactly what it was but its sporangium were covered by white calyptra that looked like a swarm of tiny insects with white wings.

Here is a shot of one of the spore capsules from the moss in the previous photo. The spore capsules have a white (when dry) 2 part calyptra that doesn’t appear to be hairy, and I haven’t been able to identify it. I have a feeling it is another moss in the Polytrichum family but I don’t know that for sure. Sporangium means “spore vessel” in Latin, and of course that’s exactly what it is. Note the long beaked lid at the end of the capsule, which is its operculum.

The liverwort that was mixed in with the moss in the previous photos was the greater whipwort liverwort (Bazzania trilobata.) It lives happily on stones right along with mosses so you have to look closely to be sure what it is you’re looking at. This pretty liverwort looks almost like it has been braided and always reminds me of a nest full of centipedes.

Each greater whipwort leaf is about an eighth of an inch wide and has three triangular notches at its base. This is where the trilobata part of its scientific name comes from. It means “having three lobes.” You might notice though, that some have more than three.

There was a good bit of ice on the roadside ledges but it was rotten and falling so I didn’t get too close.

Drill marks in the stone of the ledges tells the history of this place. This road was one of the first laid out in the town of Keene, built to reach the first sawmill. If you didn’t have a sawmill in town in those days you had a dirt floor. Or one made of logs, which was probably worse than dirt.

It turned out to be a beautiful and relatively warm day. The lack of snow on the old abandoned road made walking a pleasure. I’ve seen this natural canyon with so much snow in it I had to turn back.

The yellow lines are still here on the old road, but since nobody has driven here since about 1970 they really aren’t needed.

One of the best examples of a healed frost crack that I know of can be seen here in this golden birch. Sun warming the bark in winter can cause a tree’s wood to expand. If nighttime temperatures fall into the bitterly cold range the bark can cool and contract rapidly, but when the wood beneath the bark doesn’t cool as quickly as the bark the stress on the bark can cause it to crack. On cold winter nights you can often hear what sounds like rifle shots in the woods, but the sounds are really coming from cracking trees. They can be quite loud and will often echo through a forest.

The spot where this yellow jelly fungus (Tremella mesenterica) grew was heavily shaded so I had to use my camera’s onboard LED light to get a shot of it. I was surprised when I saw the photo because you could clearly see the shiny and dull, matte finish surfaces on the fungus. I’ve read that the fungus produces spores only on its shiny side, but in previous photos I’ve taken the entire thing always looked shiny. This is the first time I’ve ever seen the two surfaces in a photo so I’m quite happy to have solved another riddle, even though there are always hundreds more just around the next bend when you’re involved in nature study.

If you come upon a white spot on a tree that looks like it has been inscribed with ancient runes you are probably seeing a script lichen. This common script lichen (Graphis scripta) was bold and easy to see. The dark lines are its apothecia, where its spores are produced, and the gray color is its body, or thallus. If you happen to be a lichen there is nothing more important than continuation of the species through spore production, and script lichens produce plenty in winter.

There is a great waterfall here but unfortunately you have to just about break your neck to get to it, so since I wasn’t interested in doing so here’s a shot of it from a few years back. Height estimates vary but I’m guessing about 30-40 feet, and it was roaring on this day. Just think; history lessons, plants, ferns, lichens, mosses, fungi, liverworts, a waterfall and a brook that sings to you all along the way. Where else can a nature lover find all of these things in one walk? Nowhere else that I know of, and that’s why I come here again and again. I do hope you aren’t getting bored from seeing it so much.

I haven’t been to the Beaver Brook natural area in Keene for a while so last weekend I decided take a walk up the old abandoned road. This road was gated when a new highway was built in the 1970s, but my father and I used to drive over it to visit relatives when I was a boy.  Back then the road went all the way to the state capital in Concord and beyond, but the new highway blocked it off and it has been a dead end ever since. At what is now the end of the road is a waterfall called Beaver Brook Falls and I thought I’d go see how much water was flowing over it. We’ve had a lot of a rain this year.

The old road follows along beside Beaver Brook and was originally built to access a sawmill which was built on the brook in 1736. In 1735 100 acres of “middling good land” and 25 pounds cash was offered to anyone who could build a sawmill capable of furnishing lumber to the settlement of Upper Ashuelot, which is now called Keene. Without a sawmill you lived in a log cabin, so they were often built before anything else in early New England settlements. The headwaters of Beaver Brook are in Gilsum, New Hampshire, north of Keene.

Tall blue lettuce (Lactuca biennis) grows prolifically here and is one of the first plants I notice at this time of year because it towers above everything else. The one growing up past the top of this photo must have been 8 feet tall. These plants usually end up with powdery mildew by the end of summer and this year they all seem to have it here. I was a bit surprised to see it though because this summer hasn’t been all that humid. It could be that the closeness of Beaver Brook makes the air slightly more humid. It is also usually very still here, with little wind.

As I’ve said many times on this blog, fall starts at the forest floor and lady fern (Athyrium filix-femina) tells me that fall is in the air. This is the only fern that I know of with fronds that turn white in the fall.

If you aren’t sure that you have a lady fern by its fall color you can always look at its sporangia, which are where its spores are produced. They are found on the undersides of the leaves and look like rows of tiny black eggs. The little clusters are usually tear drop shaped.

Hobblebush (Viburnum lantanoides,) one of our most beautiful native shrubs, was also whispering of fall.

Hobblebush berries start out green then turn to red before finally becoming deep purple black, so they’re at their middle stage right now.

A hickory tussock moth caterpillar (Lophocampa caryae) crawled on a goldenrod leaf. This black and white caterpillar can cause quite an itchy rash, from what I’ve read. The nettle like hairs can break off and stick in the skin and they are said to bother some people enough for them to be hospitalized, so it’s probably best to look and not touch this one.

When Indian pipes (Monotropa uniflora) turn their nodding flowers to the sky it means they’ve been pollinated and are ready to set seed. The plants will turn brown and become hard like wood, and finally the seed pods will split open and release the tiny seeds. They are dust like and are borne on the wind.

Orange crust fungus (Stereum complicatum) grew on the underside of a fallen branch. This small fungus has a smooth whitish underside with no pores. The complicatum part of the scientific name means “folded back on itself” and the above photo shows these examples just starting to fold. It also likes to grow on the logs of deciduous trees. It can be seen from quite a distance because of its bright color.

Ledges show how the road was blasted through the solid bedrock in the 1700s. The holes were all drilled by hand using star drills and there are still five sided holes to be seen in some of the boulders. Once the hole was drilled they filled it with black powder, lit the fuse and I would imagine ran as fast as they could run. There are interesting things to see here among these ledges, including blood red garnets, milky quartz crystals, many different lichens and mosses, and veins of feldspar.

It’s worth taking a close look at the ledges. In the right light the spore producing fruiting bodies (Apothecia) of smoky eye boulder lichens (Porpidia albocaerulescens) turn a beautiful blue. It happens because of a light reflecting, thin coating of wax that covers each one. In different light they can appear black, gray or whitish but in this light they glow different shades of blue and are as beautiful as jewels.

Another beautiful thing that grows on stone here is rose moss (Rhodobryum roseum.) Each little rosette of leaves looks like a tiny flower, and that’s how it comes by its common name. Rose moss is a good indicator of limestone in the soil so it’s wise to look for other lime loving plants in the area when it is found. This is a relatively rare moss in my experience; this is the only place I’ve ever found it.

One of the reasons I came here on this day was to get photos of purple flowering raspberry fruit (Rubus odoratus,) but I was surprised to see several plants still blooming. This plant is in the rose family and the 2 inch wide flowers might look like a rose at first glance, but one look at its large, maple like leaves will show that it isn’t. Flowering raspberry has no thorns like roses or raspberries but Japanese beetles love it just as much as roses and it’s common to see the large leaves looking like they’ve been shot full of holes. The plants are a little fussy about where they grow but they will thrive under the right conditions, as they once did here.

The fruit of purple flowering raspberry looks like a large raspberry. The plant is closely related to thimbleberry (Rubus parviflorus) and gets its common name from its fruit. I’ve never eaten one but some say that they’re close to tasteless and others say they taste like dried raspberries. The plant is unreliable as a source of berries though; I’ve seen many clusters with no fruit at all and others that had 5 or 6 flowers bearing only a single berry. Native Americans had over 100 uses for this plant, both as food and medicine.

Chances are you don’t see anything wrong with this view of the old road but I was appalled when I saw it. Thousands of wildflowers used to grow right over the road almost to the yellow lines on each side. There was a narrow, 2 person wide path through here last time I came, but now the city workers have come in and plowed all of the plants away. Without even having to think about it I could list over a hundred different species of plants that grew here and were plowed up.

Here is the view from where they finally stopped plowing up the plants. You can see how far they grew into the road in this spot but this doesn’t accurately show how it used to be because this is pretty much the end of the road just above Beaver brook falls, and few ever walked here. The plants didn’t grow quite so far out toward the yellow lines where people regularly walked.

And here is what is left of the plants; decades of growth just rolled off to the side like so much worn out carpet. Just think; many of the growing things at the beginning of this post and hundreds more like them just kicked off to the side. You would think before doing something like this that they would call in a botanist or a naturalist, or at the very least buy a wildflower guide so they knew what they were destroying but instead they just hack away, most likely thinking all the while what a wonderful thing they’re doing, cleaning up such a mess.

They’ve peeled the road right back to the white fog line at the edge of the pavement. This is what happens when those who don’t know are put in charge of those who don’t care; nature suffers every single time. What these people don’t seem to realize is that they’ve just plowed away the whole reason that most people came here. I’ve talked to many people while I’ve been here and most came to see what happens when nature is allowed to take back something that we had abandoned. You marveled at the history before you; the charm of the place was in the grasses and wildflowers growing out of the cracks in the pavement, not a road scoured down to just built condition. New Hampshire Public Radio even did a story about the place precisely because it was untouched. The very thing that drew so many people to the place has now been destroyed, and it will be decades before it ever gets back to the way it was. I certainly won’t be here to see it.

A lot of people also come here to see Beaver Brook Falls, but to get a clear view of them you have to climb/ slide / fall down a very steep embankment and then climb over large boulders. It’s becoming more dangerous all the time and now younger people are about the only ones who dare do it. If you broke an ankle or leg down here it would take some serious work and several strong men to get you out, but Instead of cutting the brush that blocks the view of the falls from the road so people don’t have to make such a dangerous climb down to the brook to see the falls, the city would rather spend their money plowing up all the wildflowers.

This is the view as you’re leaving. Where the road is narrower is where they left a few yards of growth at the start of the road, but I wouldn’t count on it being this way the next time I come here. You might say “Big deal, who cares about a few old weeds?” But what grows in those unplowed strips of vegetation includes blue stemmed goldenrod; I’ve never seen it anywhere else. White wood sorrel; I’ve seen it in one other place. Field horsetails; I’ve seen them in one other place. Plantain leaved sedge; I’ve never seen it anywhere else. Yellow feather moss; I’ve never seen it anywhere else. Thimbleweed; I’ve never seen it anywhere else. After wandering through the destruction for as long as I could stand it I had to go into the woods for a while because, as author David Mitchell said: Trees are always a relief, after people.

Lord, what fools these mortals be! ~William Shakespeare
