Most of natural grassland areas (savanna, prairie, pampas) are outside of Europe. However in Europe,
natural=grasslandis used to tag abandoned, formerly cultivated land and wasteland, covered with wild grasses and/or other herbaceous plants.
The thing I want to map is neither savanna, prairie, pampas, nor is was it formerly cultivated. My reading of the wiki is that I should hence not use the tag in Europe.
I have no idea why the wiki says this, though.
Do you think natural=grassland would be ok for my use?
