Thanks for your replies.

The land itself has been degraded by the tree felling, but there are still loads of birds - including a green woodpecker, and foxes, and I will see if I can find hedgehogs too. The removal of dead wood and open land would definitely be detrimental to wildlife. One of the most worrying things is that the driveway is narrow and occurs on a bend, so how lorries/trucks and materials will actually get in there is a mystery to me.

I've sent my comments to Lewisham anyway, and given that we live on the ground floor of 107, I hope they'll be taken seriously.
