I think there are some areas in the Zone where dogs and domestic goats are prohibited - to protect the native sheep.
Could be, Wagga, but a restricted area would probably be defined with something other than a slightly darker shade of green. I think they chose this color scheme for the small map scale to emphasize the lack of accuracy in the data. A dramatic color contrast would imply an accurate delineation, especially at small map scales. The boundaries seem a bit willy-nilly to me so I'm sticking with my etch-a-sketch theory for vegetation. I hope my colleague can find the source layer and then we'll know for sure. As I mentioned above, this mystery layer is raster data in GMAP, so he'll have to either find a really good legend that explains it, or the original vector data layer that was merged into the base map. Maybe he'll have another trick up his sleeve, he's amazing at this stuff.
