decay detection, weapon of choice?

[czhey]

I have read a lot of work on this subject, and I am happy that my knowledge of decay fungi will help me evaluate wether it is too risky to drill or within acceptable perameters.

 

I also think i have an idea how we might prevent this spread, but thats a research project that I cant do just yet.

 

Sshwarze and Mattheck have both written pieces on this issue, I will try and find an internet source or link and post them here.

 

That would be great, just can't get my head round how drilling holes in a tree can be good for it long term!

 

thanks

Do you not worry about the effects on tree health from drilling holes in it?

 

 

If a tree warrants drilling there must be some evidence that things are wrong... The last thing to worry about is if the drill may have a negative effect..

Hes right too!

 

Its a case of need to know, if symptoms are telling you theres something suspect going on then what choices do we have?

 

There is no other tool better for investigation than the Core method, with which you can test residual strengths of wood. If there was better way we would all of heard of it by now!

 

There are times when drilling is unadvisable, with g. australe for instance, but given this fungis aggressive strategy its usualy chips for the tree anyway, and certainly in a high risk zone. though heavy reductions might be a viable option, if only in the short term.

Good point, thanks.

I've never seen the core method used so wouldn't know how good it is

 

So do you go on a course or something to learn when you can/can't use drilling methods (G. australe) or is it down to the individual using their knowledge of the fungi present?

 

Thanks, very interesting.

I dont know of any specific courses on increment cores? anyone?

The LANTRA PTI course includes a consideration of the various types of decay detection equipment.

 

I've not done the tech cert, but I'd be surprised if they didn't teach/assess it as well.

 

[Tony Croft aka hamadryad]

I thought the tech cert was an intermediate qual for lower ranking surveying etc? rather than full blow decay detection and more advanced consultation work?

Sorry to post a bit random but heres a link to decay detection technology...Sorry if it is posted elsewhere already!

Not exactly, for the tech cert you need to know what technology / kit is available for decay detection, rather than knowing how to use it.

I ve done PTI and it aint s**t with respect depth of knowledge of decay technology......
