Because, if it is Oxford ragwort that is spreading along roads
and if it rarely invades pasture, then controlling the ragwort
by roads is unnecessary. If Oxford ragwort is starting to invade
pasture by the way of road verges, then that needs attention.

You claimed that it was important to know whether an infestation was of
Oxford or Common ragwort.
Your remark has nothing to do with that distinction.
