Evaluación de dos perturbaciones simultáneas en bosques de Araucaria-Lenga, usando diferencias de índices espectrales

This study assessed the impact produced by a wildfire and an infectious outbreak led oomycete pseudofungi, both occurred in 2015, on state of Araucaria-Lenga forests China Muerta Reserve, placed southern Andes Chile. To do this, greenness vegetation spectral index was calculated over multitemporal set Landsat-8 images, acquired biannually near-anniversary dates, which subject to subtractions between ex-ante (2013) ex-post dates (2015, 2017, 2019). Results show magnitude temporal progression disturbances, highlighting celerity aggressiveness wildfire. Although affected land covers currently values close recovery primal biomass, inclusion field-based data deepen possible composition structure variations these is needed.
