Abstract |
ABSTRACT Victorian temperate forests, characterized by variable wildfire response traits, such an analysis is missing hindering fire impact estimation over large areas on operational basis. To close this gap, we have evaluated 10 remotely sensed indices across eight areas affected by wildfires in 1998, 2006, 2007, and 2009 which comprise 13 forest types. The analysis was carried out at forest type level and as a function of the regeneration strategies (seeders, basal and epicormic reporters) and structure (tree height and canopy cover) with the six forest groups. Index performance was evaluated by (i) examining index response across four fire severity levels, (ii) the separability index, and (iii) the optimality values analysis. A ranking scoring system was used to compare the index performance to distinguish among severity classes. Initial results demonstrated that there hasn't been a consistency of the best indices capacity but there a consistently worse index among forest groups. |
