Posts Tagged ‘White Poplar’

Last Saturday was a beautiful warm spring day and though there was plenty of snow left, it was melting fast. The “plenty of snow” part of things is what dictates where I can go in winter because many parking areas have been plowed in or not plowed at all. Not only that but many places don’t see much foot traffic in winter so the snow hasn’t been packed down. This rail trail in Keene solves all of those problems and that’s why I chose it. There is plenty of parking space and the snow has been packed down by snowmobiles, making it easy to walk on. If you step off that packed trail though, you could find yourself knee deep in snow, so you have to keep that in mind.

I admired the branch structure of the trees against the beautiful blue of the sky. This one is a white poplar (Populus alba,) which is a weak tree that often loses large limbs. In ancient Rome this tree was called Arbour populi, which means tree of the people. These days it is also called silver leaved poplar. It originally came to the U.S. from Europe in 1748 and obviously liked it here because now it can be found in almost every state. It is very common here in New Hampshire and is considered a weed tree.

One of the easiest ways of identifying white poplar is by its diamond shaped lenticels, which are dark against the whitish bark. Another way is by its leaves, which are green on top and white and wooly underneath. The tree has a shallow root system and suckers aggressively from the roots, so it is best not to use it as an ornamental.

The native tree population in the area is mostly maple, pine, birch, and black cherry. This forest is young; I can remember when it was a cornfield, and knowing I’m older than the trees makes me feel a little strange. I can’t remember exactly when they stopped farming this land but if I go by the size of the tree trunks it couldn’t have been more than 25 or 30 years ago.

I finally saw birds eating birch seeds. This gray birch had a whole flock of them in it and they let me stand 5 feet away and watch them feed until a snowmobile came along and scared them away. These aren’t good photos at all but I wanted to show that I wasn’t imagining things when I say that birds eat birch seeds.

I tried looking these small birds up and the closest I could come was the black and white warbler, because of the stripes you can see in this  poor shot.  There was a resounding chorus of birdsong all along this trail on this day and now I know who was singing at least part of it. How could someone not be happy when so many birds are?

The whole of both sides of this trail are lined with American hazelnut bushes (Corylus americana) and I like the way the green-gold catkins shine in the spring sun. I looked several time for signs of them opening, but not yet. When they open there will be a single bright, yellow-green, male flower peeking out from under those diamond shaped bud scales.

As I was taking photos of these sapsucker holes I could hear a woodpecker drilling off in the distance. Yellow bellied sapsuckers are in the woodpecker family but unlike other woodpeckers they feed on sap instead of insects. They drill a series of holes in a line across the bark and then move up or down and drill another series of holes before moving again, and the end result is usually a rectangular pattern of holes in the bark. They’ll return to these holes again and again to feed on the dripping sap. Many small animals, bats, birds and insects also drink from them, so these little birds helps out a lot of their forest companions.

I was admiring the sunshine on black cherry branches (Prunus serotina) when a plane flew by. A single engine Cessna practicing stalls, I think. It flew in a nose up attitude and was surprisingly quiet.

This black cherry had a bad case of black knot disease, which is what caused the growth seen here. Though it looks like a burl it is not; it’s caused by a fungus called Apiosporina morbosa. When it rains the fungus releases spores that are carried by the wind to other trees and almost every cherry along this trail had the disease, which is always fatal if it isn’t cut out of the tree when it’s young. It also infects plum and other ornamental cherry trees. It’s often mistaken for the chaga mushroom but that fungus doesn’t grow on cherry trees. Note the tree’s platy, dark gray bark with horizontal lenticels. Black cherries can grow to 80 feet tall and 2 to 3 feet in diameter if they aren’t attacked by black knot.

I saw what I thought was snow on a fallen branch but it was a bracket fungus that had degraded so badly it had become paper thin and the purest white.

I reached the point where ash swamp brook meets the Ashuelot River and there were two small black and white ducks here, splashing across the water very fast; so fast I couldn’t get a shot of them. They were probably half the size of a mallard with dark and light colored bodies and they could really move.

I used to come here as a boy and watch the bank swallows that lived in this embankment. That’s all soil, probably 10 feet deep, from the brook to the top, all deposited as river silt over who knows how many thousands of years and soft enough for the birds to dig in. It’s no wonder farmers have farmed this land for centuries. “Rich bottom land” I believe they call it.

The brook and river still flood to this day, and you can usually see huge plates of ice all around the trees in this area in winter, but I didn’t see any on this day.

I was able to climb / slide down the hill into the forest to get a shot of the trestle I stood on to take the previous 3 shots. This trestle is known as a “double intersection Warren pony truss bridge” and was probably built around 1900. It is also described as a lattice truss. Metal truss bridges were used as early as 1866 but railroads didn’t begin using them until around 1870. By 1900 they were common and replaced wooden bridges, which occasionally burned and often were washed away in flooding. I’ve seen water almost up to the bottom of this one and that’s a scary sight.

Some of these old Boston and Maine Railroad trestles have been here for 150 years and if man leaves them alone I’d bet that they’ll be here for another 150 years. I wish I knew if they were built here or built off site and shipped here. I do know that the abutments were built here from local granite, all without a drop of mortar.

Ash swamp brook was very low but since it hasn’t rained and no snow had melted for a week or so I wasn’t surprised. This brook meanders through parts of Keene and Swanzey and originates to the north of Keene. Hurricane brook starts it all near a place called Stearn’s hill. It becomes white brook for a while before emptying into black brook.  Black brook in turn empties into Ash Swamp, and the outflow from the swamp is called ash swamp brook. It finally meets the Ashuelot river at this spot after changing names at least 4 and maybe more times. I’m guessing all the different names are from the early settlers, who most likely didn’t know they were looking at the same brook. It’s quite long and I doubt anyone has ever followed it from here to its source.

I saw a small oak branch that was full of split gill fungi (Schizophyllum commune.) These are winter fungi that in late fall and I was happy to see them because I’ve been looking for them all winter but hadn’t seen any. They are about the size of a penny and are very tough and leathery.

Split gill fungi wear a wooly fur coat and this makes then easy to identify. Split gills grow on every continent except Antarctica and are said to be the most studied mushroom on earth. Scientists have isolated a compound in them that is said to inhibit the HIV-1 virus.

The “gills” on the split gill fungus are actually folds of tissue on its underside that split lengthwise when the mushroom dries out. The splits close over the fertile spore producing surfaces in dry weather and open to release the spores when they’re rehydrated by rain. It’s a pretty little mushroom, in my opinion.

It’s spring fever, that’s what the name of it is. And when you’ve got it, you want — oh, you don’t quite know what it is you do want, but it just fairly makes your heart ache, you want it so! ~Mark Twain

1. Stream Ice

This year winter seems determined to overstay its welcome and has brought record low temperatures and record high snowfall amounts. Even though we’ve had mini thaws where the temperature rose to 40 degrees for a day or two, most of the time we have been well below freezing during the day and below zero at night. Because of that the snow that has fallen is melting very slowly.

 2. Melting Snow

The snow in the woods is knee deep, which makes going rough. I recently bought some gaiters to keep my pant legs dry and make life a little easier, but another good storm will mean snowshoes for sure. One way to make it easier to get around is to look for south facing spots like that in the photo above where the snow has pulled back some. These are great places to look for mosses and other plants that stay green throughout winter.

 3. Fern on Ice

Ferns might look fragile but evergreen ferns like this intermediate wood fern (Dryopteris intermedia) aren’t. This one was growing in the midst of an ice sheet. There aren’t many ferns that are evergreen in New England so winter is a good time to hone one’s identification skills by getting to know them. This one is very similar to the marginal wood fern (Dryopteris marginalis). Both the words “intermediate” and “marginal” in the fern’s common names refer to the placement of the spore bearing structures (sori) found on the undersides of the leaves.

 4. Evergreen Christmas Fern

Another fern commonly seen in winter is the evergreen Christmas fern (Polystichum acrostichoides). This one is easy to identify by its leaflets that resemble little Christmas stockings. The narrow fine teeth that line the edges of the leaflets and the short leaf stalks can also be seen in this photo. When seen at this time of year it is obvious that evergreen Christmas fern has had its branches flattened by the weight of the snow because they splay out all over the ground. Once new fronds emerge these will brown and die off.

 5. White Poplar Bark

Winter is also a good time to learn how to identify trees by their bark since there is no foliage in the way. A tree with light to dark, mottled gray bark with diamond shaped marks in it is a young white poplar (Populus alba). The diamond shapes are the tree’s lenticels, which are air pores. The bark on white poplars can be very white at times like a birch, but it is usually light gray when young. Older trees have darker gray, furrowed bark at their bases.  White poplar was introduced from central Europe and Asia in 1748. It can now be found in every state except Alaska, Arizona, and Hawaii.

 6. Hedwigia cillata Moss 

Mosses are easy to find in winter if you look at logs and stones where the snow has retreated. This Hedwigia ciliata moss with its white leaf tips is usually found growing on boulders and is very easy to identify. Common names include Hedwig’s fringeleaf Moss, Hedwig’s rock moss, and Fringed Hoar-moss. Johann Hedwig was a German botanist who studied mosses in the eighteenth century. He is called the father of bryology and lends his name to this and many other mosses.

 7. Slender Tail Moss aka anomodon attenuatus

This moss has never appeared on this blog in this dry state before. Long-leaved tail moss (Anomodon attenuates) is also called tree apron moss because it is quite common on the lower part of tree trunks. When wet its leaves stand out from the stem and it takes on a more feathery appearance and looks completely different than it does in the photo. This is a good example of why serious moss hunters do so after it rains.

 8. Moss aka Dicranoweissia cirrata

This is another first appearance on this blog. Curly thatch moss (Dicranoweissia cirrata) grows on rotting logs and stumps and is very small, with leaves that curl when dry. After a rain its leaves will straighten out and this moss will look very different than it does in this photo, which is why I’ve found it so hard to identify. Tiny growths on the leaves called gemmae are intended to break off to perpetuate the species.

 9. White Cushion Moss

White cushion moss (Leucobryum glaucum) can appear silvery, white, bluish green or grayish green but it always forms a thick cushion and stands out from the mosses that might surround it. It likes plenty of water and shade and grows on rotting logs or on stone when there is enough soil. It is probably the easiest of all the mosses to identify.

 10. Beard Lichen

March is a month known for its wind and anyone who studies nature can take advantage of that fact, because there are all kinds of things falling from the trees at this time of year. This beard lichen (Usnea) was lying on top of the snow and at 4 1/2 inches long is the longest I’ve ever seen. It is said that if you take a single strand of this lichen and gently pull it apart lengthwise you’ll find a white cord inside, but it must take extreme magnification to see it because I’ve never been able to.

 11. Gilled Bracket Fungus 

Another bracket fungus that mimics the common turkey tail (Trametes versicolor) is the multicolor gill polypore (Lenzites betulina).  Since turkey tails have pores and these have gills they are hard to confuse. Multicolor gill polypores start life very white but turn gray as they age. They have some zoning like turkey tails and are often covered with green algae.

 12. Gilled Bracket Fungus Closeup

This is an extreme close-up of the underside of the multicolor gill polypore in the previous photo. These are clearly not pores.

NOTE: Thanks to help from a knowledgeable reader and more experience identifying fungi I now know this to be the Thin-maze flat polypore (Daedaleopsis confragosa). The photo does actually show pores but they’re elongated and can resemble gills. I’m sorry if my incorrect identification caused any confusion.

 13. Hobblebush buds 

In my last post I talked about bud how scales enclose and protect buds throughout winter. Not all plants use bud scales for protection though; some like the hobblebush in this photo have naked buds.  Instead of using bud scales plants with naked buds often use fine hairs like those that can be seen on the fuzzy leaves and stems of the hobblebush. If there isn’t a flower bud between them the tiny naked leaves almost look like hands clasped in prayer. I like to imagine that they’re praying for spring like the rest of us, but I don’t know for sure.

This post is about firsts as much as anything else; the first post I’ve ever done in black and white and the first post that’s been about photography more than the subjects of the photos. This is also the first time I’ve had to see things so very differently, and for that I have Patrick Muir to thank. Patrick has a blog called Patrick’s Garden, which you can visit by clicking here. He saw the first black and white photo to ever appear on this blog and challenged me to do an entire post in black and white, so Patrick, this one is for you.

 1. Dead Tree in Ice

I thought I’d start at the beginning with this photo of a dead tree that I posted back in December. Though I admire photos by people like Ansel Adams and Dorothea Lange I haven’t ever been very interested in black and white photography, but then I saw a black and white photo on Tootlepedal’s blog (another one worth a visit) and thought it might be fun to give it a try. I found out by doing this little project that color can actually be a distraction and a hindrance, and sometimes you don’t really see until you remove the distraction.

 2. Dim Sun

Often in winter the world is more black and white than anything else so it was no work at all to turn the photo above and the first photo of the dead tree to black and white. If I showed both the color and black and white versions side by side you could barely tell which was which.

 3. Pixie Cup Lichens

These pixie cup lichens (Cladonia asahinae) are the color of wood ash but many times they look almost white in a certain light. They have a granular, pebbly surface and the absence of color makes it much easier to see.

4. Japanese Knotweed Seed 

This is the seed pod of Japanese knotweed (Polygonum cuspidatum). The plant itself is a terribly invasive weed that is almost impossible to eradicate, but its tiny whitish seeds have three wings that fly 120 degrees apart, and make up a papery husk around the seed. I never noticed the texture of their wings until I saw them in black and white.

 5. Icicles  in Black and White

Ice and water seem to make good candidates for black and white photography. The icicles are much easier to see.

6. Mushrooms on a Log 

Long time readers of this blog have probably heard me talk about my colorblindness at one time or another. The kind I have isn’t severe but, though I can see red and green traffic lights, if a red cardinal lands in a green tree he disappears. The above photo was rejected because it was (to me) monochromatic, showing only varying shades of brown. The mushrooms almost blended into the background but in the black and white version they really stand out.

7. Tree Wound 

Tree wounds can be interesting but this one seems even more so in black and white. The absence of color helps me to think more about shape and texture.

 8. White Poplar Leaf

If you find something that looks like a maple leaf but has a deep green upper surface and a pure white underside, it is a leaf from a white poplar (Populus alba). Making this photo black and white did nothing to the leaf-it really was as snow white as it appears in the photo.

 9. Mushroom Gills

I like how the texture of the oak leaf that this tiny mushroom cap is sitting on becomes almost reptilian when seen this way.

 10. Hoar Frost

The dark water and white hoar frost again meant little change when this photo became black and white.

11. Gray Birches in Winter 

This photo of gray birches (Betula populifolia) was another one that showed little change from color to black and white.

12. Lowbush Blueberry Blossoms 

Last September, on a very foggy morning, I climbed Mount Caesar in Swanzey and found a lowbush blueberry (Vaccinium angustifolium) blooming long after any blueberry should have been. I posted the color version of this photo then, but I like the black and white version more. The water droplets make sense because of the dense fog, but I still can’t figure out what would have caused the bubbles on these tiny blossoms.

This was a fun post, if for no other reason than forcing me to climb out of my comfort zone and try something new. I feel though, because black and white photography is very easy in the winter when the world is black and white, that I’ve cheated a bit, so I’ll do another black and white post in the summer or fall. I have a feeling that will be a real challenge.
