Cryptostroma corticale is evidently a pathogen that went from the US to Europe. Used to be Coniophorum? aka maple-strippers disease...Anyway folks in Europe are wondering about potential treatments...
And I'm wondering about it switching from saprobe to pathogen here, with rising temps and...
If you like it there, no reason not to let it do what it is doing. Sapsucker damage looks worse than it actually is.
No need to halo prune for light on dead limbs; they ain't coming back!
You are much further north than JD so it may have a longer life. I used to live up your way; Madison...
Absolutely! Removal is a common recommendation; not yours! Sorry to be unclear (and rant).
It is a bad actor, and I agree with the toppling at the base scenario. Hence the load reduction prescription, and the need to monitor. That's also why the tomograph was taken at 5 cm from grade...
Financial sense my foot. You are no pauper, and as Mr. Cervi points out, CEUs cost is zero or negligible. So I also wonder what you are talking about. I would think that keeping liability insurance would be the financial question; or have you been working without?? Gasp!
But I do have to...
The lower right pic on this slide is a white oak with B.b. Removed a 38# conk in 2006 where there was construction damage circa 1932 (right side of image). Reduced it "9%" in 2008 and 2010. Owner died; new owner rebuffs my entreaties to continue. Tree looks good today. Shingle oak in Cincy...
I'm a BCMA; for 6 years I've been managing a shingle oak with this fungus in NE Cincinnati. Your pic shows the fungus is consuming already-dead wood, but the scar tissue on either side of it looks very strong. I would not worry about climbing the tree but YES it's good to get an experience eye...
Installing a system typically takes me an hour or so for a 100' tree. Not counting the installation of the ground. Not difficult.
I've seen fuses on A300 Part 4-specced systems on 3 continents that recorded up to 5 strikes. No tree damage. I know Ben has a different view. His fasteners are...
evo I have heard that verification happens. They do need your money to function, but they also want you to be successful. But I agree the bar(s) could be a lot higher. TRAQ was abysmal imo.
Practice tests might help--if you want to immerse into tree risk, send me your answers. Free grading...
JD he has a reference list at the end.
Nice to see people trying to sort this out, but absolutism does not fit the entire range of scenarios.
Sugar stick concept was Shigo's not DD's, and removing deadwood for health still fits many cases.
I learned the "kick test" in Europe; retaining...
Sounds like a branch-by-branch decision.
I used to give an expected lifespan, but after a while I became aware that there were so many unknowable factors that I was just pulling numbers out of my aspirations for credibility.
Yes, do the worst 2 first.
I've seen that partial severing thing tried but have not seen any less girdling as a result. That seemed logical when I read it in the Costello book, but it was just based on theory.
Great talk at ISA yesterday on laurel wilt. Bottom line: Propocanizole remains the only control; paclobutrazol just delays it.
The beetles look like a scavenger on that beech.
