Mike, Are you OK, Buddy??? The extinction of mankind is pretty strong medicine, don'tcha think?

You just need a big, fat HUG, Man. Either that, or you're a hopeless, terminal cynic and need a slap upside the head.

Now get your head out of your butt and use your power to DO SOMETHING that'll make a difference. What do you need from us to make a positive impact?

Now come over here and give Uncle Tree Machine a big hug. Now get to work.

Mike, one doesn't have to be a conservative or a Republican (pretty much a meaningless term anyway) to question the validity of the "global warming" theories being loudly proclaimed.&nbsp; I just saw on the news the other day that Indy never even hit 90&deg;F this year.&nbsp; Remember when we were kids in the '70s and the cry was about the coming ice age?&nbsp; I'm not saying mankind isn't doing some stuff that's bad for the environment; I do think, however, that to <i>change</i> it (for the worse), we'd have to do a whole lot more than we are.&nbsp; I recall a couple of years ago reading an article about the ozone hole over the southern pole.&nbsp; There was a reference link to a NASA animation showing the size and shape of the hole over an extended time.&nbsp; Sure, there was a hole that expanded and shrunk rhythmically, but right outside the hole was an area that was off the charts for ozone density.&nbsp; Easily containing every bit of the gas displaced from right over the pole.&nbsp; Funny how that wasn't mentioned in the article...

Man does affect his environment, that's not being argued against, but the world is not a static place.&nbsp; Never has been to our knowledge.

Back to this thread topic: what should we do to prevent the introduction of tree-destroying elements?&nbsp; The only sure thing we <i>can</i> do would be to cease trade in wood and wood products.&nbsp; Which would be the higher cost to us?&nbsp; Both the current and contemplated results suck.

I sure don't think spraying poisons is a very good alternative.

Tree infections,etc.

If one were to study history,with regards to infections of humans,livestock and plant life,it would be apparent that most were caused by imported types of parisites.A case in point would be the native people of Alaska,and the coming of the Europien fur trappers.The native people ,would often times die,by just contacting the common cold,because they had no immunities build up against it. The case of the Dutch Elm blight,of the early 60's,nearly wiped out all ofthe giant,and then abudant American elm.For years,the surviving trees would rarely get over 12" before also dying.In recent years,I have seen some of them reach 24"before giving up the ghost,so it could be that are building an immunity in the new generations??With the emerald ash borer and the oak wilt,only time will tell.It is,however,my opinion,that these parasites,to our native trees,were brought to these shores by way of cargo holds of ships etc.,so maybe ,there lies the answer in prevention.It is my hope that something can be done quickly before 2 more of our great hardwoods are only found in history books.

Well, I certainly don't want to become guilty of derailing one of Daniel's threads...

Al, don't forget about the chestnuts.

Mike, "nucular"?&nbsp; Are you sure you aren't a conservative Republican?&nbsp; Seems they're the only ones who pronounce nuclear that way.&nbsp; :<tt>)</tt>

While admitting we (collectively) mess up the environment a little, a major volcanic eruption does far worse without our help in the least.&nbsp; I've even heard it speculated that events in the earth's past which man could in no way have been a participant have caused massive (nearly worldwide) extinction!&nbsp; While some of what we do is detrimental it's a drop in the big, big bucket.

Al, dutch elm diease was found in the US in 1930 and the Division of Forest Pathology was doing research on it in 1937 to find resistant trees. The Chestnut blight was first noticed in 1904, it wiped out most of the Chestnuts in this area by 1938. The big question is would these oaks Murph showed have died if they were not cut? Murph are only the oaks that were trimmed dying or are others dying also?

Other oaks that appear to not have been pruned are infected as well...
In reading up on the literature, I didn't see anything about infection being spread by saws. Though I suspect it could be... Maybe have to find an autoclave ig enough for the zubat and echo 3400... Anyone know the deal here? Should I stop pruning oaks until I find out?

"Speaking" for George, maybe, I'm betting the thought was more along the lines of the trees being weakened, thus rendered less disease-resistant, by having been "pruned" when so large.

Oak wilt

If I recall correctly,the chest nut blight was traced to a load of imported veneer logs in the hold of a cargo ship,in 1904.The Dutch elm blight ,was discovered in Cleveland,in 1930,and by the '60 s,had made it's rounds,don't know if the origin had been detected.Does anyone know the origin of oak wilt?My guess is that it,like the "lady bug"type beetles,that drive use nuts this time of the year,found it's way here through some kind of packing crate or wood product via imported goods from abroad.

Hey
Here some thoughts on our wisdom!
Before DED was found in north america it was all over Europe. A dutch scientist finally found the pathaogen that causes the elms to loose branches but rarely death. Over there they didn't really even notice that it was a problem because the trees just had limbs that died and then the tree added new growth. Maybe that is what the thought but maybe they just cut down the dead ones and all that was left was the genetically stronger ones that survived and then reproduced. When it got here we just cut down every one that had a sign of DED and never waited to see if it would geneticall alter it's self to continue to be a part of our forest canopy!
Before that the Chesnut Blight! Man it killed every American Chesnut around or did it! The goverment in it's effort and wisdom to control this offered $3 per stump as evidence of removed sickchesnut! Easy money for the farmers in tough economic times so did the blight kill all of them and would we have any genetic super trees of this one?
The goverment also offered Sugar Maple saplings to the farmers to replace the loss of canopy cover. The farmers were not going to give back precious farm land to the forest so they lined the drivways and field edges with them. Most people must just think these things must just reproduce in strait lines cause that is how they grow in these parts! But know we are starting to see Sugar maple decline and we are scared! Have we put much thought into that Sugar Maples grow best in stands and near the canopy cover of larger trees ie American Elm! But you say they are not altering them selves but do we know how long that takes? Do we even wonder about the maple keys blowin out into the feild and becoming turned in by the tractor was that the super maple who knows!
I guess my point is we should be very aware of what we are doing but in our hast to solve things we could be the real pathogen!
Lets hope that this oak decline and scorch will balance out things! Oak usually also grow in stands and have understory plants that help keep moisture in the ground and also add a protective litter layer to the roots of the oaks. To us this unsightly and beautiful turf is better, or a foundation for a mega home, or maybe a new parkin lot to a mega store situated along a beautiful ravine so shoppers can be more in contact with nature!
Maybe we can do something but lets explore all the reasons first!

Back to the Oak Wilt, I wonder if those got pruned during the growing season. If so that'll open them up to infection. The respectable tree services here won't touch an oak till after the leaves are off for the year. ( 2 Cents from a weekend hacker slacker).

Al,

I don't think Oak Wilt was introduced, to my understanding it was primarily a deep forest disease working on isolated stands of Red and Black Oaks.

It was never a problem in our area until they started putting housing developments in wooded areas and upset the delicate balance of keeping this disease in check.
