It’s winter. Hardwood trees are bare. But that doesn’t mean the woods are bereft of interest.
Winter, when sunlight slants in, is the time when bark comes into its own. Pause to take in the aged-brass bark of a yellow birch, or the hand-sized bark plates on a big white pine. [Read more…] about Tree Bark in Winter
Every year my husband and I cut a Christmas tree on family land. We look for a young balsam fir growing in the power line right-of-way or in a forest clearing.
Fir is our favorite type of Christmas tree because of its delightful, pungent fragrance. While Christmas tree farmers cultivate a variety of fir species, balsam fir is the only type of fir native to Northern New York. [Read more…] about Balsam Fir: A Native New York Christmas Tree
Come winter, after the bears have retreated to their cold weather dens, many backyard bird enthusiasts hang feeders to attract – and nourish – avian visitors. Birds need more than a supplemental food source, however.
Whether they are roosting, feeding, selecting a nest location, or flying from one grove of trees to another, birds rely on vegetative cover, from the ground level to the treetops. Offering natural sources of cover can help birds evade predators and find protection from inclement weather, as well as provide shelter during migration.

When clients call about decay in large older trees, every so often it’s necessary to respond that I’m not interested in hearing any lip from them. I do this respectfully of course.
It’s a frequent misconception that the roll of callus tissue or “lip” that trees produce at the margins of a wound will cause, or at least accelerate, trunk rot by catching and holding a small amount of rainwater.
It makes perfect sense to us that if an open tree wound is allowed to stay wet for longer, it will decay faster. We all know that a stack of wood exposed to the elements will turn punky in a few years, whereas if it’s kept in a dry shed it can last indefinitely.

What do the following items have in common: the Declaration of Independence, Da Vinci’s notebooks, Bach’s musical scores, Rembrandt’s drawings, Shakespeare’s plays, and the Magna Carta?
Give up?
These examples, along with countless other documents ranging from the historically important to the more mundane, were all recorded using iron gall ink, which is made – in part – from the protrusions created after oak gall wasps lay their eggs within oak trees.

“If I knew for a certainty that a man was coming to my house with the conscious design of doing me good, I should run for my life.” David Henry Thoreau’s statement, funny in a way, also brings to mind the grave harm done to cultures around the world by Western powers in the guise of “helping” them.
In a less horrific sense it applies to how we’ve “assisted” nature to disastrous ends. Cane toads in Australia, mongoose in Hawaii, Kudzu in the Southeast, and Asian harlequin ladybeetles that invade our homes each fall are a few examples of being too helpful.

Conspiracy hypotheses, or theories as we like to call them, since “hypotheses” cannot be uttered without a lisp, seem to multiply unfettered these days, so I feel awkward birthing yet another.
But you may be intrigued to learn that the wide spectrum of color in the region’s fall foliage is largely the result of a Depression-era stimulus project ushered in by the Hoover Administration. [Read more…] about A Fall Tree Color Conspiracy
The Arbor Day Foundation is seeking proposals for 2021/2022 large-scale plantings that will positively impact the environment, create habitat for wildlife, promote watershed restoration, and provide other benefits to the public.

In 1981, former President Ronald Reagan famously pronounced “Trees cause more air pollution than automobiles do,” a statement which garnered endless ridicule.
Even though he also said “Facts are stupid things” during a 1988 interview, it turns out his claim about dirty trees was partly correct. [Read more…] about How Trees Cause – and Mostly Prevent – Pollution
As a tall person, I’m a bit size-conscious, ducking to get through doorways, wondering when I’ll find another decent shoe in a sixteen – stuff like that. One thing which came as a surprise is that I can’t operate most mid-size SUVs unless I were to either remove my left leg, the driver’s door, or the steering wheel, all of which seem like bad options. Yet there’s plenty of leg room in a little Nissan Micra. Size does matter in many cases, but not always in the obvious way. This is especially true when buying a tree.
