OK, I see it now... was thinking in terms of goshen pond and not the town of Goshen before.

Yeah, looks like they just combined two parcels into one. It says Nature Conservancy in my data from the NJDEP, but there is no listing for Goshen Ponds Preserve on their website. Is this one of those properties which they later deeded to the State? That might have happened after 2020 when I downloaded parcel data. There may be more info buried in some large databases that I have, but I have too many other balls in the air now.
Looking a little closer, there were actually three lots combined, my version shows block 52 lots 8, 9 and 10. Your map shows them all combined into block 52 lot 8. Interestingly, lot 8 is just a little 1/4 acre parcel. I guess they chose the lowest lot number for the combination. If you look at the
parcel data for that lot, it shows 30.78 acres under the Land Description, which is about the size of the whole preserve.
Lot 16 is also listed as an Additional Lot in the
Block 52 Lot 9 data, but I don't see where that is
