Hello.  Thanks for pointing this out.  I had mapped a lot of this a few years ago when I was a less experienced mapper.  Some insight:

Indeed, the previous multipolygon for "Royalston State Forest" included both DCR and private CR parcels.  On the MassGIS OpenSpace data for the private CRs, there is this piece of metadata: FORMAL_SITE_NAME = Royalston State Forest.  I erroneously assumed the private CRs were also known as "Royalston State Forest".  I didn't realize there are signs that identify the private CRs as separate things.

However, the multiple adjacent private CRs are not all known as "Beals & Fleet National Bank CR".  Your recent edit labeled all as such because I previously mapped the private CRs as a single multipolgon.  Before, there was a multipolgon for the DCR parcels and a single multipolygon for the private CRs.  And then a bigger multipolygon that had all the above parcels named "Royalston State Forest".  Could be confusing!...especially if you're a new mapper.

I just redefined things so "Royalston State Forest" is JUST the DCR owned parcels.  I will go back soon to redefine the smaller private CRs and name them per what I see in MassGIS OpenSpace layer.

Please let me know if you have any on-the-ground info that may differ from the MassGIS OpenSpace data...I find it's sometimes not up-to-date.  I'm happy to collaborate to ensure this beautiful part of the state is properly mapped.  Cheers.
