Under good grazing management, native grasslands on similar soils in similar precipitation zones are co-dominated by similar plant species. Consequently, exchange of ranch drought experiences and management practices can be helpful over relatively large geographic areas, especially in the semiarid climate zone.
From North Dakota to northern Texas, sand bluestem (Andropogon hallii) and prairie sandreed (Calamovilfa longifolia) or big sandreed (Calamovilfa gigantea) co-dominate upland sites in high ecological condition on loamy fine sands.
This example looks at three sites with similar soil types and plant communities, located near Dickinson, North Dakota (N 46o 53'), Crescent Lake Wildlife Refuge (WLR), Nebraska (N 41o 43'), and Dumas, Texas (N 35o 52').
