Abstract

The Rucamanque Park houses some of the remnants of the Roble-Raulí-Coigüe mixed forest in Central- South Chile. Cortical lichens were monitored in Renoval and in the Original Remnant Forest of Nothofagus obliqua (Mirb.) Oerst. We found differences in specific richness by tree species and between the Renoval (13 species) and the Original Remnant (7 species). The variables that affect the greatest richness are discussed, suggesting that the structure of the forest may play a key factor.
