Service Description: Soil erosion (by water or wind) can have detrimental effects on ecological resources, such as forage amount, quality, plant health, air and water quality. To aid initial resource assessments to determine potential risks of soil loss on rangelands, the Conservation Effects Assessment Project – Grazing Land component developed the rangeland Soil Vulnerability Index for water erosion risk (rSVI-water). This geospatially-based index was developed using research and modeling estimates from the Rangeland Hydrology and Erosion Model (RHEM) on water erosion that occurs on rangeland. The index pairs specific soil characteristic values with NRCS SSURGO soil data to determine a risk class by soil component for water erosion. The rSVI ratings are based on dry, unvegetated soil conditions, so use may be limited to helping producers understand the importance of maintaining vegetation cover within their adaptive grazing plans. The rSVI-water will be the basis for future indexes developed on rangelands. User Guide
Purpose: To provide FPAC employees with the 2022 rSVI soil survey layers for Alaska, the Continental US, Hawaii, and Puerto Rico.
