That would seem to be a reasoned response, the two pertinent lines being:

"But the season when this is permitted under the Wildlife Act is between the start of September and the end of February the following year"

And

"The only exception is if there are road safety implications."

Thus if a particular portion of hedgerows creates a danger it can be trimmed, we don't need to destroy vast tracts of verge and hedgerow.

But as I said in another thread, we could always drive slower.
