Abstract

The aims of this study were to test the use of SPOT multispectral images for mapping burn severity, pre fire vegetation density, and longer term (2.5 years) vegetation recovery in the Giscle catchment, SE France. Indices tested include the Normalized Burn Ratio (NBR), Normalized Difference Vegetation Index (NDVI), Differenced Normalized Burn Ratio (dNBR), and Differenced Normalized Difference Vegetation Index (dNDVI). Indices were compared to field data gathered immediately after the fire and about 2.5 years later. The multi-temporal indices (dNBR and dNDVI) were more useful for burn severity mapping in the the heterogeneous foret-scrubland-vineyard environment. The second tests were on the potential impact of slope aspect on post fire vegetation recovery rates 2.5 years after the fire using a combination of field and remote sensing methods. It is suggested that relationships between topography and soil properties can be useful for mapping both soil erodibility and post fire vegetation recovery
