Thanks Andrea, I guess the best thing to do is to wait and see what the voluntry options are.
I've never been a big fan of pollen mixtures as it doesn't seem right to burn 100s of litres of diesel ploughing up ground, working it down and establishing a flower mixture that you will plough up again in 12 months, it hardly seems environmentally friendly. As wildlife doesn't sequester carbon.
I suppose it depends on which church of environmentalism you worship at!
as for skylarks the buzzards would probably scare them all off!!
but grass margins might be a runner.
