Point taken about bio security in the case of Chalara (though our attitude
would have probably differed 5 years ago, when there was still the forlorn
hope that it might be contained)

However, its as much about general awareness and proportionality surely

Eg the poor souls working on a tree with OPM (which I have fortunately never
had the displeasure of meeting) would I suggest be more acutely aware of the
need to protect exposed body parts etc and to avoid giving it a free ride to
unaffected trees/areas by whatever means

All the best

Indeed. 

And presumably arborists also disinfect their clothes, hair and other
exposed body parts and the entire vehicle and chipper and ladders and
climbing kit, etc., etc., before leaving site?

I saw a maturing ash tree here in Winchester last summer that had about 5
small shoots showing symptoms of CDoA but otherwise appeared entirely
"healthy."

It was the ONLY ash I saw around here that did NOT show signs of fundamental
infection! So I'm thinking the biosecurity horse has already bolted...

Regards,

Bill

Everything else (in the case of ash dieback) is down to practicing good
biosecurity - I guess you could argue that moving arisings from an
infected
tree/site to an operators site for burning etc reduces the risk of disease
spread, as long as that site isn't in an area where there are trees which
might be affected, and adding of course general precautionary measures eg
cleaning wheel arches/vehicles between sites, keeping
tools/equipment/boots
etc clean
