This isolated community survived during centuries thanks to the Araucarias. A perfect harmony between man and nature, forever upset by the invasion of the Spanish colonists, the conflicts of territories and the increase of logging. Protected today, this sacred forests are the refuge of a unique and wild nature; but fires threaten this balance. What remain of these people and the link with this tree? What can they teach us about our environmental problems?
