A multi-scale, multi-temporal analysis of NDVI in burned landscapes

Prescribed burning, a common fire management practice is routinely carried out by government departments and land management agencies to reduce wildfire hazard. To understand and measure the impacts of these fires on the landscape, spectral data from Eucalypt trees of an Australian dry sclerophyll forest was captured pre- and post-burn at two spatial scales. Results of this research indicate that NDVI was able to detect significant epicormic growth in response to the burn event at the object scale. The timing of NDVI decrease and returns were comparable at the two spatial scales considered in this paper.
