Heat changing the way wood reacts. Caution.

hahaha yes it is davey. ive been an arborist for ten years. last year they bought the company i was working for. the way trees are reacting to the heat is a real issue. more or less extreme depanding on where you live and work. don't hate the arborist, hate the company.

Before we deteriorate into some sort of natural/God/spin-doctoring, let me first say that I think this is a profoundly important thread.

When we generally come across something new and different, the facts are almost essentially anecdotal. They are commentaries in words, pass-around words spoken at first, and then later written with a likely very narrow audience.

We are that very narrow audience. We are the first encounters with many of the surprises and concerns in these beginning threads. Another reporting group for encounters will be the loggers, who may almost by definition are dealing with older larger trees, but might not be as well-networked in discussions and observations in our various sites.

There is however, one critical distinction in that loggers fell entire trees and do not disassemble, deconstruct, or take them down a little bit of the time because of the surrounding locations. To arborists, this is an inherently hazardous potential.


I have talked repeatedly about nature probably never using averages to determine the positioning, chosen routes or other evolutional directions. There would seem to be no genetic encodings with a practical outcome that so precisely takes a whole and divides it by the sum of its parts--as we do in our little mathematical peculiarities.

We are in fact so preoccupied with this artificial drivel that I have to seemingly endlessly endure a blend of dogma and percentages of one-turd rules and the like that rarely has anything to do with what were talking about.

We are trained to be simplistic--in part because that's how we give away our money to those that think they are entitled to it. We pretend that we search for the simple, i.e., smallest and single solution, as if nature keeps itself in a neatly tight order to protect us from brain freeze.

Well here we are again. Some things are occurring that are outside the familiar and predictable, and trees ain't quite acting in the same ways before they bumped into new conditions.

Some of us are puzzled and concerned--and rightly so. Trees that don't act in the way that we would've thought they will, appear to be hazardous possibilities that will take some time before they catch up with peer review and other considerations.

Right now, I can't be quite as articulate as I would like to be, except to say that these are important “from the field” reports and we should be talking about them seriously.

But again some will ignore, mock and dismiss new information with hardly a glance-about to really consider the issues.


Anyway, I'm about to go off into left field because I have this stupid idea that we should be teaching people to be smarter--and safer--and healthier--and perhaps live out their declining years with a reasonable surrounding of circumstances.

So, let me repeat a little political factoid that Tom Dunlap pointed out to us:

Texas Republican Party Calls For Abstinence Only Sex Ed, Corporal Punishment In Schools

Early this month, Texas Republican delegates met in Fort Worth to approve their 2012 platform, notable parts of which take aim at the state's education system.

In the section titled "Educating Our Children," the document states that "corporal punishment is effective" and recommends teachers be given "more authority" to deal with disciplinary problems.

Additionally, the document states the party opposes mandatory pre-school and kindergarten, saying parents are "best suited to train their children in their early development."

The position causing the most controversy, however, is the statement that they oppose the teaching of "higher order thinking skills" -- a curriculum which strives to encourage critical thinking -- arguing that it might challenge "student's fixed beliefs" and undermine "parental authority."

The party also notes its encouragement of legislation that prevents "non-citizens unlawfully present in the United States" from enrolling in public schools, a stance that federal officials have previously deemed against the law.

In March, U.S. Secretary of Education Arne Duncan told Bloomberg he felt "very, very badly" for Texas students.

"Texas may have the lowest high school graduation rate in the country," Duncan said, according to Bloomberg.

The following weekend, former White House press secretary Robert Gibbs gave his own criticism of the state's education system.

"I think when it comes to someone like Rick Perry, [voters are] going to wonder why a place like Texas has one of the worst education systems," Gibbs said on "Meet the Press."

Wow, everything is falling apart, trees are exploding, and we are going to be teaching our kids to be more stupid?

I have much respect for you and my simple answers are only in response to questions that can not be easily answered.

Heat is only one variable in the equation. My only point is excluding all the others is missing the mark.

My apologies for the diservice.

Quickest way to smarter children = remove commercial TV from your home.

Rope Shield, don't worry--no disservice taken.

I enjoy your enthusiasm and predisposition to land on the ground running in 6 different directions. It's a nostalgic review of my own early energies.

We have 2 unavoidable and unarguable conditions: heat and drought--which are not the same circumstances. We also have new unpredictable moments that threaten our own personal safety and the safety of others below. I'm not expecting an immediate answer, and already some new thinking might be on the horizons.

I agree with you completely. We should mostly absorb and be very careful about excluding facts that fit our prejudices and dogmas. One of the next posts from the troops may very well be a serious injury where we had no warning flags associated with the accident.

Keep sluggin'

The crews from the Colorado Springs Waldo Canyon fire reported fire behavior they had never witnessed before (in today's Denver Post: http://www.denverpost.com/ci_21081160/re...denverpost.com) For instance, it moved almost as quickly downhill as it did up hill. And it didn't die down at night, with the cooler air. Trees are very dry.

Fred, thank you for an important reference.

Nature is assembling a new set of facts--and throwing away a lot of "records". I'm really sick of listening to "meteorologists" keeping us to a “seven-day prediction schedule” and ignoring the politically incorrect words like “global-warming” and "global-warning”.

Because the neocons and the scientifically-shriveled have distant and closeted agendas, why are we to be denied an honest factual prediction of what August will be like this year.

We pretend, or least some of us pretend, that global warming issues are irrelevant because of some dim scholarly debate. That's all marketeering lined up in a row--don't unsettle the customers; if they're worried, they won't spend.

Dutiful lemmings that we are, we ask no serious questions, we push for nothing expected, we bury ourselves in blue-collar graves, and we might sputter minorly at the last shovelful of dirt in our face.

But then again what else is new?

This way to the egress.

whats the rainfall been like for you guys this year? do you think maybe a lack of rainfall and the heat coulda been the onset to these barberchairing issues? perhaps really dry wood?

our wood in hawaii (except prosopis pallida)is really wet. yestarday i spent an hour unplugging one of the center knife pockets on our woodsman 12X that got plugged with wet albizzia wood. it was like coconut husk and i had to pry and beat it out with a hammer and pry bar.
 
Mb next time heat it up till dry whilst doing the splits and then beat the brittle out of it.

Its been in 30's but humid and droughty here in Southern Ontario. Clients will barely come outside to talk and offering for us to come inside to the A/C for breaks and lunch.

Summer to hot to work, winter to cold to work.
Either way I enjoy it because I got no choice in the matter.

Cheers
 
note the word explosion is used loosely here.,

I think this needs a physicist but here goes.

Vessels contain dissolved oxygen (and other gases). If drought is so severe that cavitation occurs can we expect exploding wood?

If cavitation does not occur can we still apply the combined gas law? Assuming that volume of the vessel does not change, than pressure must increase as temperture increases. Does this cause the explosions?

A temperature increase from say a normal high of 33 celcius to say 40 celsius is not likely to cause intact trees to explode from increased pressure but does cutting allow the explosion to happen?
