0-057 Shingle oak (Quercus imbricaria) is native and common in our area, but we know that the several large trees running east from this point all were planted long ago due to their straight-line distribution and uniform spacing. Shingle oak is the only oak species native to central Illinois that has narrow leaves with neither teeth nor lobes and it looks like no other Illinois oak. It can be found in transitional habitats in nature. Woody galls seem to favor this species and pin oak above all others, but individual trees vary considerably in their susceptibility to the tiny wasp gall makers.
