The forested parts of the park are dominated by American beech, eastern hemlock, and various oaks and hickories. Let’s go look at some plants!

Ohio geologist Jane Forsyth, in a 1971 article “Geobotany” explained the relationship between vegetation, soil type and the geologic history of Ohio. Wahkeena is contained within the unglaciated Allegheny Plateau, a region that includes southeastern Ohio and is characterized by erodible shale capped by erosion resistant sandstone. The result after erosion is deep valleys of steep-sided sandstone hills. There is a suite of species, including several woody ones, that are found mainly in this environment. They are acid-loving plants.
