There is also the issue of planting trees which are not native to British West Oxfordshire and the resulting influence on the local eco-system.....
If you read the newspaper and the number of court cases between house holders about said tree's in the area its not as if your introducing something new.
And as for the ecosystem I am sure they plant these bloody newt things when ever they hear there is a project kicking off. I was at a project civilian that involved an old oil pipe yard. The planning permission was put in for a shot blasting plant and the newts aspect reared its head. Funny as the area in question had been covered in radioactive scale for years and used to get sprayed down with diesel. And one of the reasons why the spot was chosen was they were going to have to dig out 3 m down anyway to get rid of the contamination.
They found newts. And two weeks later lots of dead newts. Didn't stop it dragging out for years though. They wanted it decontaminated then left to see if they would come back. Not much chance of that after they replaced the bottom two meters with sandy soil and the top with local top soil. Best drained bit of the yard after that.
