i know the Narbonensis was relatively developed compared to the rest of Gaul but it can’t have had that little forest cover, right?
unless the area is naturally plainy :shrug-outta-hecks:
I thought the non-forested stuff was farmland - it seems to be split up in roughly rectangular chunks, and those little bits of green separating the chunks could be windbreaks. It seems like a ton of land though, don’t know how much farmland a Roman city like this would have (or if would be right outside it like that, I think the Romans did a lot of farming in villas some distance away from cities).
