This looks visible on MassGIS 2019 Orthos, but the excursion to the west does not appear there.

Maybe this path connects and maybe there is a gate. Needs a field check.

This parcel belongs to the state, per MassGIS data (parcel 25-10-0). However, it is mapped as HSV -- which it felt like on the ground. This all doesn't quite make sense; perhaps there is a lease. It would be good for someone local to figure this out, and either fix it if needed, or leave a note= on the polygon explaining why the ownership and use don't match.

This parcel belongs to HSV per the current OSM data, and to the state per L3 parcels. HSV is acting like it is theirs (lease/?), so I've left it for now, but it needs figuring out.

vernal pool

orchard open to the public, probably "George Hill Orchard"

geometry appears troubled

It is not clear that this is actually used for forestry, vs being a nature_reserve and conservation land that is named Town Forest.

This is apparently named for someone, and proper naming should be checked.

There are multiple parcels shown on L3 parcels. Needs checking which ones are town owned and which are formally in the forest.

There are a number of parcels on L3 and it is not clear that the OSM geometry matches the parcels that are actually owned by the town and considered part of the forest.
