Blackjack oak shares dominance with bluejack oak and sand post oak (Q. stellata var. margaretta) on the slightly more mesic midslopes of sandhills, downslope from the xeric ridges that support turkey oak (Q. laevis) . The Pine Plains of New Jersey are characterized by a community of dwarfed blackjack oak, bear oak, and pitch pine (Pinus rigida) .
