Hello :<br><br>
I have put together as an attachment a short relatively non-technical
document about the scientific and logical issues behind the proposed tree
felling in Alexandra Gardens for anyone who might wish to read it. The
aim is to make people think about the often re-iterated statement by the
Chief Arboricultural Officer (the form varies) to the effect that the
trees have been <u>shown </u>to be the agent creating the subsidence upon
which the felling proposal rests.<br><br>
Until we see the independent surveyors report, which the Council officers
have not yet released, it is impossible to judge the 'data' on which this
conclusion is based. However, I have tried to show that it is not at all
simple and that we should rid ourselves of the simple equation of (tree
roots)=(serious water extraction)=(drying/subsidence)=(required felling)
which seems to be axiomatic in the minds of many people.<br><br>
Anyone really interested (and with a bit of time !) should read - or pick
the relevant plums out of - the London Tree Officers Association report
of 2008, which makes the case against blaming trees for too much of the
subsidence in London and the role of the insurance companies (see
relevant bits above, also).<br><br>
