Tree Buds

Striped Maple Buds

3-11-14 striped maple terminal bud 132Striped Maple (Acer pensylvanicum), also known as Moosewood and Moose Maple, can easily be identified summer or winter by its greenish bark bearing vertical white stripes (hence, its common name). Because the bark is so distinctive, one needn’t rely on Striped Maple’s buds for identification purposes, but they are well worth investigating, nonetheless. Their graceful shape, smooth surface (few bud scales) and pinkish-red coloration distinguish them from all others. These buds and young branches that bear them are devoured by rabbits and hares, are frequently eaten by porcupines and beavers, and provide browse for deer and moose.

Bitternut Hickory Buds

1-10-14 bitternut  hickory 102Habitat, silhouette, bark and buds can all be helpful when identifying a tree in winter. Occasionally a species has one characteristic that is so distinctive, it serves as a diagnostic feature. The sulfur-yellow coloring of Bitternut Hickory (Carya cordiformis) buds is such a characteristic. Both lateral and terminal buds have a powdery coating which gives them a bright yellow appearance. Look for Bitternut Hickory on moist lowlands (hence, its other common name, Swamp Hickory) and rich uplands. Although humans find the nut of this hickory inedible, the smoke produced by burning its wood produces the best “hickory-smoked” hams and bacon.

Naked Buds

12-5-12 flower and leaf buds of hobblebush IMG_6226Tree buds are formed in the summer, so if you look at a tree today, it will have buds on it, in the axils of where the leaves used to be (on deciduous trees). There are two kinds of buds – leaf buds and flower buds (flower buds are typically fatter than leaf buds). Both are usually covered with scales which help seal in moisture to protect the bud from drying out during the long, dry winters when water is frozen and therefore unavailable. Different types of trees have different types and numbers of scales. There are a few trees whose buds lack scales completely; these buds are referred to as “naked.” Witch hazel (Hamamelis virginiana), bitternut hickory (Carya cordiformis) and hobblebush (Viburnum lantanoides) all have naked buds. In the photograph, a hobblebush leaf bud is on either side of a flower bud.


A Great Christmas Present!

If you’re looking for a present for someone that will be used year round, year after year, Naturally Curious may just fit the bill.  A relative, a friend, your child’s school teacher – it’s the gift that keeps on giving to both young and old!

One reader wrote, “This is a unique book as far as I know. I have several naturalists’ books covering Vermont and the Northeast, and have seen nothing of this breadth, covered to this depth. So much interesting information about birds, amphibians, mammals, insects, plants. This would be useful to those in the mid-Atlantic, New York, and even wider geographic regions. The author gives a month-by-month look at what’s going on in the natural world, and so much of the information would simply be moved forward or back a month in other regions, but would still be relevant because of the wide overlap of species. Very readable. Couldn’t put it down. I consider myself pretty knowledgeable about the natural world, but there was much that was new to me in this book. I would have loved to have this to use as a text when I was teaching. Suitable for a wide range of ages.”

In a recent email to me a parent wrote, “Naturally Curious is our five year old’s unqualified f-a-v-o-r-I-t-e  book. He spends hours regularly returning to it to study it’s vivid pictures and have us read to him about all the different creatures. It is a ‘must have’ for any family with children living in New England…or for anyone that simply shares a love of the outdoors.”

I am a firm believer in fostering a love of nature in young children – the younger the better — but I admit that when I wrote Naturally Curious, I was writing it with adults in mind. It delights me no end to know that children don’t even need a grown-up middleman to enjoy it!


Black Walnut – Identification in Winter

This slideshow requires JavaScript.

Black walnut (Juglans nigra) is a relatively easy tree to identify, as it has so many distinctive qualities. In the summer there are round, tennis-ball-sized nuts, which have a delightful smell.  The bark of black walnut is dark and deeply furrowed.  Best of all are the twigs and buds.  If you cut a twig at an angle, you will see the central portion, or pith, is chambered.  It is also brown.  The only other tree that is chambered (not solid) like this is its relative, butternut (Juglans  cinerea), and butternut’s pith is buff colored.  The buds of black walnut are greyish and fuzzy – lacking bud scales.  By far the most amusing thing about black walnut (and butternut) is its leaf scars – the scar left when a leaf falls off.  The vessels that transport food and water, called vascular bundles, are darker than the rest of the scar, and are shaped in such a way that the leaf scar resembles nothing more than the smiling face of a monkey!  (Butternut leaf scars also look like monkeys, but they have a “furrowed brow” of fuzz on the top edge of the leaf scar.)

 


Yellow Birch (Betula alleghaniensis)

Yellow birch (Betula alleghaniensis) buds are oval and pointed, and there are two shades of brown on each of their 3 – 5 bud scales.  The buds and twigs of yellow birch taste like wintergreen.  In the early morning and late afternoon, look for ruffed grouse filling their crops (“budding”) in yellow birch trees, as these buds are one of their favorite foods.  The thin bark of a mature yellow birch is a very distinctive yellow-bronze color (the bark of saplings is a shiny red-brown color), and curls when it separates from the trunk.
