yep, government interference as opposed to other government interference

So are you really saying that the significant loss of the traditional farm
species of the UK such as some butterflies never disappeared through
intensification.

I accept that grants from government were sometimes the enabling factor



Incidentally there is still a very viable population on Salisbury
Plain, where the agriculture is not very intensive, and so many of the
other declined agricultural species still thrive.

It is going to be genuinely interesting to see what the next five years
