"You have probably been asked this question once or twice before,"
No, I haven't as it happens.
"but why did you cut down mature olive trees in the first place ?
If the answer is, they were in the wrong place,you could have simply had the loading shovel pick them up and move them to my land !"

I presume you're joking but just in case you're not, here are some answers.
There were over twenty of them in three rows adjacent to the house.  If they'd been productive I'd have been delighted to leave them where they were but they weren't.  Some time before I moved in, this place had been a commercial nursery and the trees were planted about a metre apart and were effectively stock.  I tried to sell them but when the potential buyers realised they weren't in pots, they lost interest.
I didn't join the forum until 2008 and these were grubbed up in 2007 so I didn't know of your existence or requirement.
The thought of making about twenty round trips from my place to yours up the A340 with a huge Caterpiller with about a ton of olive in the bucket (of God knows what variety) sounds a bit far fetched.  And would you have been prepared to pay for that ?

Why did you buy the land if you were so unhappy about it's history ?
