I know at least one that's not excluding any other landuse, but has
apple trees planted sparsely on the grass that covers most of the area,
the German word for it is "Streuobstwiese", and that's used even in the
English wikipedia for it .
At least that single example, located around here  (and not in OSM
yet), matches that combination, but I guess it's more often the case.
Of course you are right for some parts of protectioned area for the same
purpose, but it's not the water well field alone that protects the area
or excludes different usage IMHO.
Nevertheless a tag for that kind might be useful.
