Abstract
          
            Background
            Cultivation of exotic pine species has increased in areas of Araucaria moist forest, which is an ecosystem with high biological diversity. Land planarians are generally susceptible to replacement of natural habitat by exotic tree species plantations. However, how planarian communities respond to the invasion of exotic species in natural habitats is unknown: (1) Are there differences in richness and abundance of land planarians between sites of Araucaria moist forest with (AMF-P) and without (AMF) pine trees and between these areas and pine plantations (P)? (2) Does the species composition of land planarians vary among AMF, AMF-P, and P?
          
          
            Results
            This study shows that mean richness and abundance of land planarians per sample unit are higher in AMF sites than AMF-P sites. In addition, AMF sites have a higher estimated richness per sample unit than pine plantations and AMF-P sites. In AMF-P sites, mean richness and abundance are higher in sample units not influenced by pine trees than in those with pine needles. An ordination analysis indicated that the communities of each site are distinct, especially the communities of the AMF and P sites.
          
          
            Conclusions
            The present work demonstrated negative impacts from a recent invasion of an exotic species of pine on the richness and abundance of land planarians in a site of Araucaria moist forest and significant variation in the planarian community composition between sites of Araucaria moist forest and pine plantation.
