In some instances,broom <br /> snakeweed will increase. <br /> This plant community is resistant to change due to grazing tolerance of buffalograss and blue grama.A significant amount of production and <br /> diversity has been lost when compared to the Reference Community. Loss of cool-season grasses,fourwing saltbush,and winterfat,and <br /> nitrogen-fixing forbs have negatively impacted energy flow and nutrient cycling.Water infiltration is reduced due to the massive shallow root <br /> system,the'root pan"characteristic of sodbound blue grama and buffalograss.Soil loss may be obvious where flow paths are connected. <br /> Desertification is advancing. <br /> https://esis.sc.egov.usda.gov/ESDReport/fsReportPrt.aspx?id=R067BY002CO&rptLevel=al... 1/2/2018 <br />
