The rear dunes are older, protected from the waves by the foredunes, and support a more established plant community. Early pioneer plants have left behind a layer of humus, which nourishes the characteristic dunesland plants including Horizontal Juniper, Bearberry, Sand Cherry, Puccoon, Prickly Pear Cactus, Little Bluestem, Canada Wild Rye and Sand Reed Grass. As these plants add additional humus to the soil, prairie, dominated by Little Bluestem, takes hold.
