Ecological site concept
Currently there is only a draft of the initial concept for this ecological site. The initial concept for this site places it within the Seasonally Flooded Basin Wildrye Ecological Site Group.

The Dry Floodplain (023XY005NV) ecological site is the modal site for this group. This site occurs on the outer margins of axial-stream flood plains, fan skirts and along intermittent drainageways. Slopes gradients of 0 to 2 percent are most typical. Elevations range from 4500 to 6000 feet. Average annual precipitation is 8 to 12 inches. The soils in this site are deep, light colored, silty to clayey in texture and are moderately slow to slowly permeable. A seasonally high water table within 5 feet of the surface is usually present in the early spring. These soils are subject to periodic flooding. The plant community is dominated by basin wildrye and basin big sagebrush (Artemisia tridentata sp. tridentata) with a lesser component of western wheatgrass. Black greasewood is present on this site. Production ranges from 1300 to 3000 lb/ac with normal year production estimated at 2000 lb/ac
