These days it’s no shock to learn that officials may not always give us the most up-to-date information on a fairly new disease which poses a grave threat to the public. The surprise is that it doesn’t involve COVID-19. [Read more…] about Ticks & Lyme Disease: A Primer
Old Trees Play A Unique And Essential Role
Typically, “tree aging” is done by counting annual growth rings, either on a stump or on a sample core taken by a special tool. But the phrase can also refer to veteranization, a process whereby trees are prematurely aged through targeted injury and stress in order to create specialized habitats. It’s much like the ageing of parents, a treatment administered by one’s children to produce worry lines, grey hairs, and character.
We humans whistle past the cemetery, as it were, with refrains like “50 is the new 40,” apparently hoping to trick death into giving us a free decade somewhere along the line. For trees, there is no single definition of old. A mountain-ash is decrepit by fifty, while a bur oak of that age is a mere adolescent. Every species has a lifespan range beyond which no amount of wishful thinking or supplements can help. [Read more…] about Old Trees Play A Unique And Essential Role
A Poison Ivy Vaccine May Be Available Soon
Now that the V-word has joined the list of things we mustn’t say in polite company, I hesitate to bring up the topic. No, I mean the other V-word – vaccine. Even if vaccines give you a headache, there’s a new one on the horizon which you may well like.
I realize this claim smacks of a Green Eggs and Ham-style discourse. Not to worry; I won’t stalk you with promises that you’ll like getting jabbed with a mouse, in a house, in a box, with a fox, here or there, in car, or anywhere. Now that I think on it, Green Eggs and Ham was a creepy kid’s book. [Read more…] about A Poison Ivy Vaccine May Be Available Soon
Climate Science: Does Rising CO2 Benefit Plants?
Scientist-like persons hired by the fossil fuel industry have long maintained we should celebrate an ever-increasing level of carbon dioxide in our atmosphere. This gas, a key building block in the photosynthetic process, can enable plants to grow faster and get larger. It’s been called the “CO2 fertilization effect.”
Many crop yields are projected to increase. And bigger woody plants, the reasoning goes, can amass more carbon, thus helping to slow the rate of CO2 increase in a handy negative-feedback loop. [Read more…] about Climate Science: Does Rising CO2 Benefit Plants?
Plan for a Better Spring: Some Tree Ideas
Looking for a way to enhance property value, save energy costs, boost mental health, and help the planet in one simple, low-cost step? Yeah, me too. Let me know if you think of something.
Seriously, though, a few well-placed trees in one’s yard typically add at least 5% to a property’s value. Having large older specimens (of trees, I mean) around the house can push that figure close to 20%. In terms of energy savings, deciduous trees on the southern and western sides of a house tend to slash cooling costs by roughly one-quarter.

Acorn Woodpeckers: Adorable Acorn Adorners
While my musings about nature generally focus on southeastern Canada and the northeastern United States, there are times when a subject is far too juicy to ignore even if it’s out of this world, like Japanese satellites made from trees. Back home on our little planet, we have a blind, rainbow-hued marine worm which slices fish in half for the joy of it.
This “Bobbitt” worm grows to ten feet long and can paralyze a human with its venom. Also cool but way less terrifying, a rainforest tree on the island of New Caledonia oozes more nickel than the richest mines are able to yield. [Read more…] about Acorn Woodpeckers: Adorable Acorn Adorners
Counting on Arthropods
Whether one has owned a pet cat, dog, chinchilla or what-have-you, or merely admired the grace and beauty of a horse or deer, most of us develop positive links with at least one four-legged animal. But for everyone except maybe scientists, warm and fuzzy feelings evaporate when you move up to critters with a thousand or more legs.
Insects, all of which have six legs, seldom elicit an oxytocin feel-good rush. I mean it’s unusual for folks to get doe-eyed over a mosquito, yellow jacket or cucumber beetle. On the whole, though, insects are nowhere near as creepy as eight-legged beasties. The term arachnid, I’m pretty sure, is Latin for “things with too many legs for my comfort level.” It includes ticks, which can transmit around a dozen serious illnesses to humans, as well as spiders. These latter, of which we seem to have an innate fear, are equal parts by weight of legs, eyes and hairs, by my estimation at least. [Read more…] about Counting on Arthropods
Mustard Power: An Historic Food Crop
First domesticated in Central Asia some six-thousand years ago by ancient cultures looking for the best way to ruin shirts, mustard has evolved from zesty warm to blistering hot to the point that it’s now being developed as an ultra-low emission jet fuel.
Given the large size of the mustard or Brassica family – some 3,000 strong, according to Cornell University – it’s no surprise that it comprises historic food crops, showy flowers, noxious invasive weeds, and more. [Read more…] about Mustard Power: An Historic Food Crop
Where There’s Wood Smoke, There’s Pollution
A recent upswing in woodstove use might sound yawn-worthy, but recent findings about the dire health effects of wood smoke might mean the long-term future of wood as a heating fuel is in question.
As someone who grew up with wood heat, I assumed it was hands-down one of the most sustainable, eco-positive fuels for home heating. Like many other widely shared conventions, it turns out the veracity of that assumption depends on a lot of things.
How many people burn wood in a given locale is an obvious factor. The number of homes using wood heat rose sharply in the years following the 1998 ice storm which left residents without power for weeks on end. Also no surprise, the COVID-19 pandemic has accelerated the use of wood heat. [Read more…] about Where There’s Wood Smoke, There’s Pollution
Microplastics: All That Glitters Isn’t Green
We’re told that diamonds are eternal, but it turns out that glitter, which is just as sparkly and way cheaper, could be equally enduring. Parents, teachers and day-care providers know that despite their efforts to wash the stuff down the drain, glitter will inevitably wind up in their breakfast, their eyes, or on the lapels of their business suit worn to a crucial meeting with the boss.
I never would have imagined that glitter could be a pollutant of concern. At my age I need glasses to find a postage stamp – it’s a long shot that I could help pick up glitter. It seems fair to ask whether there aren’t bigger fish to fry. [Read more…] about Microplastics: All That Glitters Isn’t Green
