>>> Lawns are lame monocultures

You haven't seen my lawn. ;-)

My view is that the local people seem to prefer a park with cut grass, and these volunteers are helping them out. If the people want something else, they should decide.

lawn: a stretch of open, grass-covered land, especially one closely mowed, as near a house, on an estate, or in a park.

Might it be a meadow instead of a lawn?
