Bill and collective,

*Maybe, *but will maybe do? Sure, as I hope I made clear, it depends. Each
case should be considered in its own context. But individual cases cannot
be generalized into operating principles, no?

Here's a link to GSV (dated 2009) of a rather fine Oak tree of my
acquaintance: https://goo.gl/maps/5hFMFPMmj58pQHFd9
Note the fairly complete lack of any die-back. I can inform you that when I
measured it a couple of years ago it was 1000 mm diameter (at 1.5 metres)
and still showing no signs of any die-back. Gawdalonenose how long the
ploughing's been going on, although it seems to have ceased over the last
couple of years. I presume that the low hanging branches mean that it was
only ploughed by some traditional farming type with a little grey Ferguson
with no cab or roll bar, otherwise they'd have been knocked off.
Can't draw any conclusions from this but I'm fascinated by the lack of any
obvious signs that the ploughing's been detrimental. There is now planning
permission to put 20 odd houses in this field, and if plans are followed
the tree will find itself in the centre of a 25 metre diameter RPA. Maybe
it'll perk up like Gilbert's Ash.....

A client (former life) once bought a corner of an arable field that
dog-legged in to his garden. In doing so he relieved an ash (c.dbh
40cms) on his former boundary from having its rooting area ploughed
annually. Some seven years later he got me to fell said ash tree because
it interfered with his powered para-glider take-off area! Looking at the
cross section of the trunk, it was striking how a marked increase in
ring width exactly coincided with the period since the rooting area was
no longer ploughed.

Hi Bill, I'm not trying to argue anything. One of my clients has a

about a tree report that has prompted this query.

How would you argue that one? "Oh the tree's used to root damage cos
it's
had roots ploughed off regularly...." I think that's misinterpreting
what
the guidance is trying to achieve Mike.

Has anyone ever come across instances of reducing a tree's root

or
can
it be justified?
