A deforested area of at least 4,500 square kilometers in the Brazilian Amazon, three times larger than the city of São Paulo, Brazil, is ready to burn. The result of the sum of what was felled in the first four months of last year—still not burned. This fallen vegetation on the ground can go up in smoke with the dry season that began in June in another season of intense fire like we observed in 2019. If this happens, the number of hospitalizations for respiratory problems can increase significantly, putting further pressure on the region’s healthcare system, which is already severely affected by COVID-19.

Fire, fragmentation, and windstorms: A recipe for tropical forest degradation

Widespread degradation of tropical forests is caused by a variety of disturbances that interact in ways that are not well understood. To explore potential synergies between edge effects, fire and windstorm damage as causes of Amazonian forest degradation, we quantified vegetation responses to a 30‐min, high‐intensity windstorm that in 2012, swept through a large‐scale fire experiment that borders an agricultural field. Our pre‐ and postwindstorm measurements include tree mortality rates and modes of death, above‐ground biomass, and airborne LiDAR‐based estimates of tree heights and canopy disturbance (i.e., number and size of gaps). The experimental area in the southeastern Amazonia includes three 50‐ha plots established in 2004 that were unburned (Control), burned annually (B1yr), or burned at 3‐year intervals (B3yr).
