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