This Soil Regolith dataset covers State Forest land for the South CRA Area,
The North East of NSW and Eden CRA by
The Soil Regolith dataset was created specifically for Forestry Corporation of NSW (formerly State Forests NSW), to comply
with the conditions of Enviromental Protection Authority (EPA),
Pollution Control Licence (PCL).
The Soil Regolith classification on this dataset, groups soil types by their
stability characteristics as outlined below:
R1 : C1SD1 - C1 Coherent materials, SD1 Low sediment delivery
R2 : C2SD1 - C2 Non-Coherent materials, SD1 Low sediment delivery
R3 : C1SD2 - C1 Coherent materials, SD2 High sediment delivery
R4 : C2SD2 - C2 Non-Coherent materials, SD2 High sediment delivery
R1 depicting the greatest stability and R4 depicting the least stability.
This soil stability classification or soil regolith, interacts with rainfall
erosivity factors and slope steepness, through a series of matricess designed
for each of the different logging operations. This relationship aims to
achieve an indication Erosion Hazard, for which operational conditions and
restrictions are outlined in the PCL.
Rainfall Erosivity featureclass was originally created by the then Dept of Land and Water Conservation in 1998 using GENAMAP to create a 1km grid squares and supplied as an ASCII file. The Ascii file was converted to 1km raster in ArcInfo and then to polygons. The data has subsequently been modified by the FCNSW GIS Unit to accommodate data gaps within the original data.
