By the way, SSE want to take 120 acres of my land to build a marine energy substation. This land is one of the few remaining habitats for the Great Yellow Bumblebee. What should I do about it?
What do you mean they want to take it? Do you mean they want to buy it from you or have they power to vest it from you whether you want to sell or not.

If you hold the cards it is up to you whether bumblebee habitat is more important than hard cash. Your call.
personally I never give a sh1t about money so would not be tempted to sell something I was happy to keep for a sum of money.
Being honest I suppose my head could be turned if it were silly money I could invest elsewhere, but I would also be thinking of what my neighbours would like on their doorstep for the next 50 years or so.
