Here in Cyprus we don't have the 'problem' of TPOs. I agree with you in principle, John, and I have no scruples about removing perrenials and shrubs that turn out to be in the wrong place but trees seem to be different, maybe it's a hangover from UK and TPOs. Having said that I'm currently clearing up after the man with the 'cherry-picker' and the chain saw who has completely erradicated a very large mulberry that was suffering from a chronic illness and was also getting rather close to the overhead electricity lines.
I have also come up with a possible theory regarding the number of Araucaria heterophylla there are in Cyprus. I was delving into the depths of my memory trying to remember why we had ours, as it wasn't something I'd purchase it must have been a gift. The tradition of giving flowers/plants on special occasions is widespread and here in Cyprus is no different. However, 20-30 years ago cut flowers were not so readily available as they are now, they virtually all had to be imported, so giving a pot plant was quite common. I seem to remember that A. heterophylla was at one period very popular in this respect. Pot plants eventually outgrow their pots, if they don't die of neglect in the meantime, and need to be moved on, so where better than in the yard outside the house. This may also explain why so many are planted so dangerously close to houses. No evidence but just a thought.
