The Tall Grass Prairie Preserve consists primarily of big bluestem (or turkey foot, resembles the bird's foot), little bluestem, porcupine needlegrass (Stipa spartea), and prairie dropseed grasses. The last known Canadian remnant population of the endangered western prairie fringed orchid (Platanthera praeclara) is within the preserve.
