The Instituto de Pesquisa Ambiental da Amazônia (IPAM) [Amazon Environmental Research Institute], born in Belém, Pará, is a scientific, non-governmental, non-partisan and non-profit organization. Since 1995, its mission has been to promote science, education, and innovation for an environmentally sound, economically prosperous, and socially just Amazon.
Fire, fragmentation, and windstorms: A recipe for tropical forest degradation
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).
