Yeah, let's not kill an entire class of native plants and replace it with artificially introduced plants. That's gonna go perfectly well because human intervention like that usually goes so well.
I have personally seen cows and goats go out of their way, crossing several hectares of pasture, to consume whatever non-grass vegetation they could find (often baby fruit trees) rather than eat the grass available to them.
Well duh. Of course they prefer to eat something else once in a while after eating grass all day.
I'm all for planting more native other plants in gardens or whatever and maybe some more native plants in nature. But ripping up an entire native ecosystem that has been there for millions of years because you dislike it is utterly deranged.
Okay fair enough. But it's different elsewhere.
Grass fields are extremely natural here. There is often also grass under the trees but that depends on the types of trees and how dense they are.
