[Talk-us-massachusetts] Fwd: landuse=conservation

[Jim Snyder-Grant]

I learned that figuring out what OSM will display by playing a games of
"what if" is remarkably fragile & slow sometimes.
I notice one can look at or download the actual stylesheets used in OSM
here:
https://github.com/gravitystorm/openstreetmap-carto.
<https://github.com/gravitystorm/openstreetmap-carto>
Some relevant observations:

   - As already said, landuse=conservation support was removed. It was
   removed in a September version of these files (not sure when the files get
   deployed to OSM).
   - The key/values of boundary=protected_area and protect_class=X  are
   both ignored.
   - The various leisure categories, and the landuse categories that aren't
   conservation are used extensively.
   - boundary=national_park is used, but is merged with
   leisure=nature_reserve in every case I could find.
