Document Summary

Modal rt is populus forest (on dark. Grasslands and shrublands maintained by fire (and possible grazing/browsing) (cutiseta) grassland on loamy black. Xeric portions of landscape are restricted to grasslands (topo-edaphic climax) Depressional areas: lower slopes populus forest fringes, high water table salix sloughs, flooded carex wetlands.
