Quercus coccinea, the scarlet oak, is a deciduous tree in the red oak section Lobatae of the genus Quercus, in the family Fagaceae. It is primarily distributed in the central and eastern United States. It occurs on dry, sandy, usually acidic soil. It is often an important canopy species in oak–heath forests.
Seedling development is typically good in old fields with well-drained loamy soils. Acorn supply is one of the principal determinants of the amount of natural cherrybark oak reproduction. Other factors include microclimate, soil properties, and stand variables. Seedling development is related to overhead release, with large openings needed.
Fraxinus americana, the white ash or American ash, is a fast-growing species of ash tree native to eastern and central North America. White ash trees are threatened by the invasive emerald ash borer .

Due to their preference for well-drained acid soils, Quercus acutissima is able to thrive and survive in various harsh locations. [6]
