Araucaria araucana, a southern South American tree species, is considered a representative symbol of Chilean forest biodiversity due to its endemicity and longevity. An expedition to Chile and its border zone with Argentina was carried out with the aim of determining the current state of this species and to establish a tree network to study its genetic variability. Eight locations were selected across the range of distribution of the species and several experimental plots were established based on the heterogeneity within each location. Field trips revealed a high fragmentation in Araucaria forests showing low or non-existent regeneration in most of its distribution area. Experimental plots allowed the identification of severely altered areas. Moreover, 371 trees were catalogued, 193 males and 178 females. The tree network established will be very useful in future evaluations of both the ecological status of the species and its genetic resources, allowing the development of conservation strategies.
