WHY SWEAT THE INVASIVES?

It disturbs me not a little that Japanese Stilt Grass, Autumn Olive, Oriental Bittersweet, Garlic Mustard and (Alabama horror come true) Kudzu is invading Floyd County.

As a biology watcher for more than a half century and as one who knows what “should” grow or not grow here, I admit to a mild panic when I have so many places just on our patch of land where every day I find new patches of field or forest conquered by plants that ought not be here. And there they are, and there they will be. I can’t keep my finger in the dike, and so I give up.

In the likely long run, it won’t matter that any given patch of Eastern Deciduous Forest is conquered by Asian trees, African shrubs and exotic vines since “our forest” of the Early Anthropocene may not continue very long in the geologic sense for much longer even as forest. So why sweat the details of merely a deranged forest where “native plants”  has no meaning?

In a century or two, the vegetation of this planet may look completely different than it does today | Anthropocene   

We used the results from the past to look at the risk of future ecosystem change,” University of Arizona geosciences graduate student Connor Nolan, who conducted much of the analysis, said in a press release.

….We find that as temperatures rise, there are bigger and bigger risks for more ecosystem change.” The changes affect both the mix of species present and the overall structure of the ecosystem – for example, forest versus grassland.

…We’re talking about the same amount of change in 10-to-20 thousand years that’s going to be crammed into a century or two,” he said. Moreover, land use change and invasive species will magnify the effects of warming.

And given this degree and rate of change, every biome on the planet is threatened with possibly intolerable perturbation to the moisture and temperature determinants that have sustained tropical forest or tundra or prairie or coral reef. And from that, all the plants and animals, insects and microbes that have evolved and adapted to those condition is at risk.

No Ecosystem on Earth Is Safe From Climate Change – The Atlantic

If climate change continues unabated, nearly every ecosystem on the planet would alter dramatically, to the point of becoming an entirely new biome,according to a new paper written by 42 scientists from around the world They warn that the changes of the next 200 years could equal—and may likely exceed—those seen over the 10,000 years that ended the last Ice Age.

If humanity does not stop emitting greenhouse-gas emissions, the character of the land could metamorphose: Oak forest could become grassland. Evergreen woods could turn deciduous. And, of course, beaches would sink into the sea.

Hotter Than It Was: Not Your Imagination

…or a liberal hoax after all.

Granted, human memory can be a leaky sieve and the tendency to make things markedly WORSE or BETTER “when I was a boy” is pretty common.

But here is a way to put facts (remember those? They were once in everyday use) behind your avuncular stories to the kiddies about it being cooler of a summer back in the Old Days.

Want to see how summer temps have changed in your home town over your lifetime? Go to this NYTimes page, punch in your date of birth and where you were born (or another city of interest) and see the graph.

The orange shading is margin of error, the solid line the point of central tendency.  And you can view birth year to today, then birth year to the end of the century (pictured above) under currently-predicted warming patterns and anticipated greenhouse gas accumulation that will push us toward or past 500 ppm of CO2 by 2100.

And viewing said facts and given my aversion to heat, moving to Floyd from Birmingham was a wise thermoregulatory choice, don’t you think? And it is even COOLER than Floyd here on the Creeks.

Where are we headed in the love-hate relationship of HumanKind with Nature (that is: the biotic and abiotic parts of the only planet we have from which all our resources are drawn)?
 
It can’t be much farther in the current direction. So who will turn the ship, and how? The WHEN of the matter must be NOW!
 
So I gave some thought to our evolving place in the natural scheme of things, and doodled it out on the back of a digital napkin.
 
Seeing something helps me comprehend a complex topic a little better. And write about it. FWIW.

What is Your Barbeque Footprint?

Labor Day for many marks (or used to mark) the end of summer and the return of the kids to school. By that time, Floyd County students will have been in sweltering classrooms for almost a month. But that is not the point. Labor Day may also be at or near the end of the outdoor grilling season. And that brings us to today’s burning questions:

► Where does my charcoal come from?

► What is my BarBeQue Footprint? and…

► What is this stuff anyway and now does it compare to Propane?

All this was triggered a few weeks back when I was at Lowes (a once or twice a year visit) and found on sale two huge bags of Kingsford Charcoal. Heck, this might be a lifetime supply at our age!

But given the fact that wood from just behind and above us most likely ended up as pellets for European Power Plants, I wondered about the history of these particular black briquets and how responsibly they are produced, and where.

Well first I found out that all sorts of organic matter can be burned while oxygen-starved to create the high-heat low-smoke product we call charcoal. It contains no COAL, by the way.

Olive pits, grape vines, and corn cobs make good charcoal. Hmmm…

► Idea: a corn-cob to charcoal industry from ag waste in Floyd and other rural counties?

Comparing the BTUs of charcoal to propane, here’s the scoop: There are 91333 BTUs in a gallon of Propane and 4.7 gallons of propane in a 20 gallon tank. So that’s about 430,000 BTUs in a typical full tank.

There are 9700 BTUs in a pound of Kingsford briquets. This makes a tank of propane approximately equal to about 44 pounds of charcoal. You can price the two and do the math. Only consider that charcoal burns hotter, gives your grilled meats and veggies the smoky taste most folks want from cooking outside, and did not come from fracked gas through pipes in sone good person’s former back yard.

But where DOES Kingsford charcoal come from—and one should ask because SOME comes at the cost of burning tropical trees. I asked Kingsford and was told they product comes from domestic lumber mill waste only.

Kingsford (charcoal) – Wikiwand https://www.wikiwand.com/en/Kingsford_(charcoal)

And final trivia fact: this well-known company derived from Ford Charcoal–as in Henry and Ford Motor Co. Early on each car was trimmed with wood and there was a lot of waste. So the idea: let’s make charcoal. And early on, the only place you could get it was at your Ford Dealership!

So get grillin before the autumn’s chillin.

Giant Hogweed is Here

I recently had the opportunity to ask one of the most knowledgeable botanists I know as many pertinent questions out of my confused and confusing plants folder as I could tastefully work into the conversation.

“Have you run across Giant Hogweed on your place?” He lives on a sizable parcel of Floyd County property that he knows well, both as a farmer and as a retired botany-educated professional. He said “Why yes I have.”

It had recently been observed in Virginia, but not the southwest part of the state.

Dangerous Hogweed Plant Found in Virginia

We talked about the so-what, and he was not optimistic that its spread could be contained, given the effort it would take and the general apathy of local citizens–even other farmers.

I contended that, even so, it made sense to me that, for sake of prevention of the health impact of this plant, we should educate folks. And so…

The best source I have found for comparing similar plants is from a New York source–a state where Giant Hogweed is long and well-established. If you want to be knowledgeable and possibly save yourself or someone you know from a really really bad time, give it a careful look. There are helpful illustrations here of five plants that bear resemblance to and could possibly be confused with Giant Hogweed.

Giant Hogweed – New York Invasive Species Information 

And I’d hope that our local network of naturalists, farmers and hikers would communicate about observations. Catching these populations when there are few individuals and they are not 20 feet tall would be preferable. We don’t want our kids coming in contact with this. And animals–who may not react to the exudate–can carry it on their coats and transmit it to human skin that way.
