Vulnerable Soils: Wind Erosion Hazard

Wind erosion hazard was digitally mapped as part of the DPIPWE Water for Profit Program to enhance identification of Enterprise Suitability by effectively incorporating a sustainability measure of vulnerable soils. The mapping shows areas where a wind erosion hazard might exist if sufficient groundcover is not maintained, which could lead to soil resource degradation through soil, organic matter and nutrient loss after significant wind events. Assigned classes are; Nil, Low, Moderate and High as classified ratings of a wind erosion index. The index was generated by combining Digital Soil Mapping (DSM) inputs of the soil properties Coarse Fragments, Sand %, Clay %, Organic Carbon %, Soil Structure, with ratings developed by the DPIPWE Land Degradation and Salinity Risk assessments. The mapping covers the entire state of Tasmania at 30m resolution.
