ded elm story

The Dutch elm disease fungus. DED can be caused by either of two closely related species of fungi: Ophiostoma ulmi (Buism.) Nannf. (formerly called Ceratocystis ulmi) and Ophiostoma novo-ulmi Brasier. The latter, which is more aggressive in causing disease, was recently recognized as being a separate species. The DED fungus was first introduced to the U.S. on diseased elm logs from Europe prior to 1930. It is unknown when the more aggressive species became established in the U.S.; however it was possibly present as early as the 1940's- 1950's, and most likely caused much of the devastating mortality through the 1970's. The less aggressive species is becoming increasingly rare in nature, and the aggressive species is thought to be responsible for most of the current mortality. Although some local resurgence of DED has been observed, there is no evidence that it is due to a change in the pathogen. Localized resurgence is more likely due to the following: (1) a decrease in vigilance in monitoring and sanitation, (2) a build-up in populations of the insect vectors, or (3) ingrowth of susceptible host trees in the wild.

Amazing! Thank you TreeVet! Do you care for this tree personally?

Yes, like I added above we just keep it clean of deadwood.

Yup Thats the one I printed up (used the printer at work) and made me a DED bathroom reader a few months ago and I'm now done, just in time.

Awesome man, yeah I'm sorry I missed that I'm a bit slow.

Another real good download JPS. Interesting to talk to some arbs in the northwest who are just witnessing ded for the first time and they are scared to death of it.

Whatever info I gave on history comes from horse's mouths so that kind of stuff can be considered "real history" without word of mouth as I said I had clients that worked in the work camps on ded removals. It is local knowledge that Doris Duke brought the first ded to the US. What a way to be remembered.

 

[treevet]

It was established historically that the disease came from Europe in the 20's and came on a ship load of logs into an Ohio port (not the South) and they were brought in by deceased billionaire Doris Duke (I used to live down the street from her estate) into Hillsboro, New Jersey. During the federal work programs of the 20's and past there were labor camps that went out and removed the diseased trees. I have met men that worked on these programs that were my clients.

I was wrong about the decade as these work camps of the CCC...Civilian Conservation Corps, were in the 30's and not the 20's where they removed DED victims as he said most with manual non'chainsaws and were happy to have a job....

This article also talks about the CCC and Dutch Elm Disease in the thirties. It also mentions that Chestnut Blight had just about cleaned out the American Chestnut in the 20's in this New Jersey town of Morristown (my brother lives there) and this was, you guessed it, another introduced disease.

This is off topic but I was wondering if anyone has come across an American Chestnut that has regenerated naturally and survived blight to this day? I came across one about 10 yrs. ago when I was marking timber for a consulting forester. It was about 16" dbh and I would guess to be about 40 to 50 yrs old. I found some regeneration AC in state forest up in northern PA that look like it had started from old AC stumps. They were all very young though.

 

[treevet]

I run across them from time to time. i could take you to a few of them in an old woods within blocks from my house. I have seen a few large trunked ones over the years but they are all stunted. We are going to plant some of the new disease resistant cultivars in this town this year.

Chestnut Blight ... another introduced disease.

You beat me to it, that and butternut canker. SOD is getting up there and with insects the ash is going to go the way of the American chestnut.

Researchers say US military introduced tree pathogen to Italian estate

2004-03-30


During World War II, soldiers from the Fifth U.S. Army set up camp at an exclusive hunting estate in Italy, regrouping between military drives north against German troops and fascist leader Benito Mussolini. Sixty years later, forest pathologists are pointing to huge gaps of dead trees in the estate as the visible reminders of that brief stay.

In a new study published in the April issue of Mycological Research, researchers at the University of California, Berkeley, and in Italy, have unlocked the mystery of how the destructive Heterobasidion annosum pathogen could have spread to the Presidential Estate of Castelporziano, which has been sealed off from the public for centuries.

They were able to trace the origins of the pathogen back to eastern North America, where U.S. troops departed for Europe during World War II. The researchers say the pathogen likely hitched a ride in transport crates, pallets or other military equipment made from untreated lumber from infected trees. It took decades for the pathogen to establish itself, but since symptoms were first noticed in the 1980s, the root fungus has wiped out large swaths of stone pine trees in the Castelporziano estate less than 15 miles southwest of Rome.

Interesting, we are the bad guys in that story.

I'm sure if we looked a little closer we could find many more stories like that; aside from the run-of-the-mill industrial soil/groundwater contamination related to capitalistic imperialism.

I find Chestnut sprouting up off old stumps all over the place in the forests in my area of Central Mass out here, biggest I've found though is maybe 2.5-3" in caliper, anything bigger is usually dead already.

Yarmouth is only a 2-2.5 hour drive from here, I'm thinking I may actually take the day off and go photograph the removal, or at least be there to witness it, would be fun to actually watch a removal I'm not involved in, less stressful that way, I'll bring a lawn chair.

 

[treevet]

post us the pictures if you do please.

If you don't make it there will be YouTube footage. I'm going up this week to do sub-filming then again for the cut to film a documentary on it. Full 1080P HD from multiple angles, surround sound chain saw soundtrack if I nail it right. There will be a DVD out if anyone is interested. I'm putting allot of work into it and have allot of people dedicating equipment to the process. I'll keep everyone posted.

That is exciting to look forward to Pink Floyd. Try to get some detailed views of the stump cut that may indicate infections compartmentalized as well as injection sites. I might buy a vid. What you gonna charge?

HD....to cool.:rockn: I would let the contractor know so there is no anxiety involved by what you are doing (could think law suit or something like that). I once stopped to watch a guy climbing in a big ash and he took a fall in the tree and slammed into the other trunk. I left immediately and vowed never to do it again unless the contractor was ok with it.

Keep us posted (literally).

I'll be documenting every nook and cranny (well as much as they will allow me to) that's why I'm not taking any chances I'm going up to do sub-filming work this week. I don't know if the video will be for sale yet, but all will be viewed.

HD, oh yes! All cameras are HD at the least 720P (I'll be up-rendering the entire film to 1080P for DVD) Like I said I have some people that are letting me borrow equipment. I called and they said it would be Ok to film and there will most likely be quite a crowd anyway with cameras (crappy footage) so I'll drop them all my card to obtain their footage to render a insane film with everyone's good footage. It will take many many many days of work to edit.

Why not take a camera and post some picts on AS from a lap top while you are up there?opcorn:

Phone as a modem Gotta love it

Yeah I'll have the 12.1 stills with me as well for photos.

Too bad I can't get a live video feed.

I'm going to ask (because it's worth a shot) to get some bucket footage but I do not think they will let me in it with them (even if it was when they first arrived before the activity drew)

I can promise you this much, for sale or not... the DVD will be dramatic.

Might be worth having a word with the History Channel to replace that "Saw for Hire" series that misrepresented our profession. (Urban Loggers or something like that). From planning to saw mill to furniture or mulch etc.

Don't even get me started on that stupid show. Haha :greenchainsaw:

Any idea how long it will take with a crane and bucket to remove this tree? I don't know if they are planning on leaving the trunk there or not. I have to have enough film with me for the cameras.

Remember a sanction of this tree has already been removed by the looks in the press photos (not these) and it appears to be the side facing the white house thats been removed.
