Araucaria araucana is an endemic species of the temperate rainforest in Chile and Argentina, declared a natural monument in 1990 and classified as Endangered by the IUCN in 2013. In recent years mega-drought and warming have been inducing decline and mortality phenomena in many stands. These enduring extreme conditions are challenging the potential of these ecosystems to recover. The aim of this research is to determine the effective drivers of tree decline by applying cutting edge techniques and analyzing wood anatomical traits (tracheid size and cell wall thickness) in A. araucana trees across its natural distribution range.

Abstract
Araucaria araucana is an endemic species of the temperate rainforest in Chile and Argentina, declared a natural monument in 1990 and classified as Endangered by the IUCN in 2013. In recent years mega-drought and warming have been inducing decline and mortality phenomena in many stands. These enduring extreme conditions are challenging the potential of these ecosystems to recover. The aim of this research is to determine the effective drivers of tree decline by applying cutting edge techniques and analyzing wood anatomical traits (tracheid size and cell wall thickness) in A. araucana trees across its natural distribution range.
