Novel Approaches and Techniques for Understanding Vegetation Fires in South America.

The authors concluded that the most reliable vegetation indices for monitoring post-fire vegetation recovery were the Leaf Chlorophyll Content Index (LCCI) and Normalized Difference Red-Edge and SWIR2 (NDRESWIR). The complexity of vegetation fires in South America is observed from two recent fire crises: the 2019 Amazonia fire crisis, which was mainly associated with deforestation [[1]], and the 2020 Pantanal fire crisis [[2]], which was triggered by unprecedented drought and heat wave events [[3], [5]]. Vegetation fires represent a major disturbance in the tropics, with South America notable for having both fire-sensitive (e.g., Amazonia and Atlantic Forest) and fire-prone (e.g., Cerrado and Pantanal) biomes. In a similar study also conducted in southern Ecuador, Maxwald et al. [[9]] identified the most reliable vegetation indices for post-fire vegetation monitoring, and analyzed vegetation recovery across different classes of fire severity. [Extracted from the article]
