TREES: THE KEY TO CLIMATE PROOFING OUR CITIES- London, 10th July 2008.
A 10% increase in urban tree cover could neutralise rising city
temperatures, but large trees with irreplaceable climate-control benefits
are being lost at an alarming rate. This pioneering conference explores
practical possibilities to reverse tree loss within current planning
framework. It can be done: our objective is to define how to do it. FINAL

What ho etc etc.
I've just come back from looking at some trees that were maliciously damaged
15 years or so ago. They didn't get killed obviousl but the damage is still
obvious; neatly drilled holes at the bases, presumably for weed killer, the
soils appear to have been polluted with oil, still apparent after all this
time, and also that old favourite Cu nails hammered in to the trunk at ground
level.
What I would like to know if someone cleverer than me could reveal, is what
is the objective of sticking Cu nails in a tree? Obviously it's a nominally
heavy metal albeit (according to my books) the least toxic of them. Cu
compounds are obviously used as fungicides so they won't do the mychorrhizae any
good...
Also has anyone ever sen a tree killed specifically by Cu nails?
No.
But I know of an old, large (probably near veteran, come to think of it)
Sycamore on an allotment that I surveyed over a number of years which
had lengths of half inch Cu (I'll stick with your designation but see
below) water pipe hammered in at intervals about a foot apart all around
the trunk. There was some associated dieback of bark around the wounds,
which I put down to physical disruption (the pipe was well and truly
mashed into the tree), but the tree as a whole was fine.
No idea where this idea arose, but clearly it doesn't work, so maybe
your caution......
I'm not mentioning Cu by its more common name, just in case someone
one day in searching out information on it's efficacy for tree killing, should
stumble on this thread and any info it may reveal. Don't wanna make it too
easy for em.
is misplaced and it's the direction we SHOULD be pointing those with an
urge to arborcide towards!
