Description :
For 2 sub-catchments with differences in fire severities in Nattai National Park, south-west of Sydney, this paper considers : 1) the links between fire severity based on SPOT image analysis and ground observations of fire severity and repellency; 2) the textural and organic/minerogenic characteristics of eroded sediment; and 3) erodibility, erosion and deposition of soils in both catchments. The fire did not trigger major geomorphological change in the study area, but fires probably cause important topsoil and nutrient depletion and may also affect water quality.
