[Talk-us-massachusetts] meadow & woods?

[Jim Snyder-Grant]

What I'm trying to map are areas that are typically brushhogged once a year
to prevent a return to woods. They have a variety of non-woody vegetation.
Some of them used to be agricultural or pasture lands. They often have
enclosing stone walls (although the clearing often doesn't get all the way
to the walls unless volunteers clear out the woody stuff near the walls:
the brush hog operators get cautious).

Thanks for the reminder to check how my choices are rendered in the main
rendering platforms for OSM. I'll let you know if that step changes
anything I'm planning to do.
