Not really. It's better, but still biassed.

It fails to point out that is a significant issue only for ragwort
growing in hay fields, when the hay is cut, ragwort and all; or that
exactly the same is true of MANY other common grassland and hedgerow
plants.

I am sure you are right - BUT the amount that there is currently
growing uncontrolled on verges and other than in hayfields will
significantly contribute to the amount which will be growing in hay
fields in the near future.
