In practice they are both types of vegetation (grass + similar).

Mappers have to base their tagging off of what can be seen: that's the
type of vegetation (grass and other herbaceous plants), plus other
clues such as fences, the presence of grazing animals, or other signs
of mowing for hay or grazing.

> The grass is not there once cut

Generallly there is still a couple of centimeters of grass leaves
remaining after mowing for hay. It looks like a mowed lawn, or the
rough of a golf course, not nearly as short as the fairway or green.

truck, during high school)
