I thought about whether indigenous was the right term. For t.americana, u.rubrum and A. saccharum, Jersey south of the piedmont seems to be the SE end of their range. You might find them within 10 to 15 miles of the eastern shore of the Delaware river. East and south of that the pine barrens begin and many trees stop growing naturally. Must have to do with sandy soil and lower ph.
Acer barbatum (Acer saccharum spp. floridanum)
Acer floridanum (syn. Acer saccharum subsp. floridanum (Chapm.) Desmarais, Acer barbatum auct. non Michx.), commonly known as the Florida maple and occasionally as the southern sugar maple or hammock maple, is a tree that occurs in mesic and usually calcareous woodlands of the Atlantic and Gulf coastal plain in the United States, from southeastern Virginia in the north, south to central Florida, and west to Oklahoma and Texas.
Doesn't come into the Del Marva and south jersey.
