King Mountain Sand and Gravel Mine Ecological Resources Assessment Page 7 birch (Betula nana) and whitestem gooseberry are fairly common shrubs, and Bebb willow (Salix bebbiana) and shrubby cinquefoil (Dasiphora floribunda) occur in drier sites near the edges. The graminoid and forb understory is similar to the floodplain shrubland except there is little Nebraska sedge.

Creeping barberry (Mahonia repens) is in the understory, and bluebunch wheatgrass (Pseudoroegneria spicata) is the dominant grass. These patches of Shrubland are not well developed, and some of the shrubs, notably the chokecherry, have been heavily browsed and are very stunted.
