Lichens: More Than Meets The Eye

A lichen covered treeWe all know correlation does not equal causation, and that it’s unfair to convict someone based on circumstantial evidence. But when every appearance points to a culprit, it’s hard to resist jumping to conclusions, which by the way is my favorite athletic endeavor. After all, the kid out in your yard holding a baseball bat might not be responsible for the ball that just smashed through your window.

A landscape tree has a rough life, by definition beset with hardships not faced by its forest-dwelling peers. When chronic stress catches up to one and it declines and dies, I often hear from the homeowner about beetles, pillbugs, mushrooms or what-not (mostly what-not) found near the crime scene that must be to blame. It’s understandable – it’s like the kid with the bat. » Continue Reading.

Halloween Natural History: Witch’s Brooms

TOS_Witches_broomHarry Potter rode one during the Quidditch matches at Hogwarts. The Wicked Witch of the West zipped around on one in the Wizard of Oz.

We’re talking, of course, about witch’s brooms. No one knows exactly why witches were associated with with flying brooms. But the trope is remarkably persistent. The witch is the perennial favorite in Halloween costume popularity rankings, and she always carries a broom, generally a twiggy bundle with a handle that doesn’t look like it would do much for a floor.

But there’s another type of witch’s broom. This one grows on trees, or, more specifically, from the tree. It’s a tightly-packed mass of shoots, a deformity caused by organisms that have invaded the tree, or a genetic mutation.

New Study: Adirondack Sugar Maples In Decline

Colorful autumn foliage

The iconic sugar maple, one of the most economically and ecologically important trees in the eastern United States and Canada, shows signs of being in decline, according to research results published today (Oct. 21, 2015) in the journal Ecosphere.

Scientists at the SUNY College of Environmental Science and Forestry (ESF) analyzed growth rings from hundreds of trees in the Adirondacks and found a decline in the growth rate began for a majority of sugar maple trees after 1970. The reasons for the decline are unclear. » Continue Reading.

When Caring For Trees Avoid Topping

tree toppedTree topping is a subject I can really get worked up about. It’s unprofessional, unsightly, outrageous, unethical, dangerous, and I even suspect it causes more frequent rainy weekends and bad-hair days. It’s unthinkable, horrible, bad, yucko, blecch! That should be pretty clear—any questions? Oh, exactly what is tree topping? Hang on. Mmmph—there, that’s better. Had to wipe the foam off my mouth.

Tree topping is the removal of limbs and or/ trunks to an arbitrary length, leaving stubs. Variably known as heading, hat-racking or tipping, it is denounced by the Tree Care Industry of America, The International Society of Arboriculture and other professional tree-care organizations. » Continue Reading.

Distressing Colors: Early Leaf Change An Unhealthy Sign

Early leaf colorIf trees held a race to see which would be among the first to have their leaves turn color, the winners would be losers. Premature leaf color change is a reliable indicator of failing health, and the worse a tree’s condition, the sooner it begins to turn.

Precious few places in the world have a fall color show like ours, and the display that northern hardwoods produce each autumn never fails to fill me with awe and appreciation. But when it starts in July, as was the case again this year on some roadside maples, I know those trees aren’t long for this world. In early August even some forest hardwoods growing on thin rocky soils began to show color, which is also unusual. » Continue Reading.

Afflictions Of Late Summer Tree Leaves Only Skin Deep

330px-RhytismaAcerinumDetailUBeing an arborist, I’m of course very mindful of complexion. Things like bruises and blemishes catch my eye, in addition to scabs, cuts, and even those out-of-place whiskers that appear out of nowhere. It sounds like a description of my aging skin, but I’m talking about blotches, warts and cuts that accumulate on tree leaves over the summer.

I suppose if we had to stand outside day and night all season, our skin would develop issues too. Those who work or play much outdoors need to be concerned about skin spots that suddenly show up. With tree leaves, that’s not the case – even the ugliest “skin” condition is generally no cause for concern. » Continue Reading.

Imagine The Adirondacks Without Hemlocks

Hemlock CathySometime after four am I woke up and left the tent. Stepping into the beams of the full moon, I walked to the shore of Polliwog Pond. Dawn was just breaking above an old hemlock stand, mist swirled above still water, and the loons began to call their old, melancholic song. In those few moments in the light of the moon and the dawn and sound of the loons I was transported to an ancient place.

The day before, I had walked from the site where I was camped with colleagues and friends on a week-long Leave No Trace course, to an an old growth forest on a height of land. Most of the trees there, and at our campsite on the shore below, were hemlock. » Continue Reading.

EPA’s Greenhouse Plan Protects Park, Sets Global Pace

1024px-Gavin_PlantOn August 3rd the U.S. Environmental Protection Agency (EPA) announced it had set tough new standards for controlling greenhouse gas emissions from fossil-fuel power plants.

This final Clean Power Plan would reduce carbon emissions by 32 percent below 2005 levels by 2030.  That is a nine-percent deeper cut than EPA’s preliminary plan, announced last year. » Continue Reading.

Woodlot Management: Losing Money By High-Grading

100_1149What do you call a dairy farmer who spends decades improving the genetics of a herd, then abruptly sells all the best animals to start a new herd from scraggly, unproven stock? Crazy, perhaps, or foolish at the very least.

Under normal circumstances, no livestock farmer culls their best animals to start over with random ones. Yet it’s common for woodlot owners to sell all the large, well-formed trees during a timber sale and leave nothing but small and defective trees to regenerate the next forest. » Continue Reading.

Climate Change is Altering Nature’s Clock

Salamander-Stager-600x383Scientist Curt Stager walks along the edge of the woods, his flashlight shining into the shallow water of a leafy, roadside pool on a dark night in Paul Smiths. It’s late April, and he’s out looking for spotted salamanders, wood frogs, and spring peepers that have migrated to shallow vernal pools to breed. After poking around for a minute, he lets out an excited shout: “There’s a salamander! There he is! He’s early!”

In the water is a dark, four-inch-long creature with bright yellow spots. In the same pool not far away, wood frogs float on the surface. In another week, pools like this will be a filled with breeding frogs and salamanders, which will leave behind egg sacks that hatch into larvae.

Spotted salamanders spend most of the year underground, so seeing them is rare except during these annual breeding migrations. Their journeys are triggered by the first rains of spring. » Continue Reading.

Are American Elm Trees On The Rebound?

TOS_American_ElmOn a recent damp May morning I walked around Dartmouth College in Hanover, New Hampshire, with arborist Brian Beaty. While he is responsible for all of the trees in the center of the campus, our visit focused on a small number of trees that require an inordinate amount of his attention. These were the college’s mature American elms – tall, elegant, and, most importantly, healthy.

Beaty wants to keep them that way, which is why he checks on the elms almost daily from early spring to late summer, and has his crew look them over every time they drive by one. “We don’t have a lot big elms left,” he explained. Of the hundreds of mature elms that once adorned the college, only twenty remain. » Continue Reading.

Trees: Understanding Roots And Root Care

PaulHetzlerTreeRootAngelaPerry4002.5April showers bring May flowers, the calls of spring peeper frogs, and of course, backhoes. Yes, it’s construction season, which for arborists and trees is also root-damage season.

As far as trees are concerned, root injury is the source of all evil. Well, most of it, anyway; chainsaws and forest fires aren’t so kind to trees, either. But regardless of the worrisome signs a tree may develop, whether early fall leaf color, tip dieback, slow growth, or even some diseases and insect infestations, the problem is below ground in the majority of cases. » Continue Reading.

Emerald Ash Borer Awareness Week

EABadult4in72DavidCappaertMichiganStateUIt’s not Dorothy’s fault, or even that of the Wizard of Oz, but the emerald city isn’t what it used to be. By “emerald city” I mean Fort Wayne, Indiana. Naperville, Illinois. Dayton, Ohio or any number of Midwestern communities that are decidedly less green than before the emerald ash borer (EAB) arrived there. » Continue Reading.

Nature As Artist: How Tree Burls Grow

TOS_BurlI’ve had my eye on this maple in my woods for some time. Not because it’s a beautiful timber tree. It’s only about eight inches in diameter, after all. But, it has an interesting burl about 14 feet up the trunk.

As a woodturner, I love the twisted wood grain found in most burls. A burl is a surprise package on a tree. Yes, straight grained wood is beautiful. I love the open grain of red oak, the milky brightness of birch, the rich burnished glow of cherry. But they are predictable. A burl is anything but.

I’m not the only one who loves burls. » Continue Reading.
