Past fire activity can be reconstructed based on charcoal and pollen records recovered from lakes. The combined analysis of pollen and macroscopic charcoal records is relevant to gain a better understanding about vegetation, climate and natural/anthropogenic disturbances relationships in temporal scales further than instrumental records. The reliability of such reconstructions depends on the knowledge about what these proxies are representing today. Very little is known about modern fire events taking place in forest and steppe ecosystems placed between 50°-52°S, and how these events are reflected by lacustrine charcoal records.
