Description :
This research analyzes the impacts of the 2002 Ponil Fire in New Mexico on landscape patterns using a moving-window analysis of landscape metrics. Categorically derived landscape metrics and a measure of fire severity, the Normalized Burn Ratio, are used to produce a quantitative, spatial distribution of landscape change. The moving-window approach is particularly helpful in analyzing large fires with considerable variability in severity, allowing greater insight into the relationship between fire severity and landscape composition and structure in post-fire landscapes. The moving-window approach also can guide researchers and managers to specific areas of a landscape where large changes have occurred and where evidence for understanding the process driving that change is most likely to be found.
