The results of the specific distribution of lichens sampled on 30 small Dodonaea viscosa L. trees located in a restinga area on the banks of Lagoa Negra in Itapuã State Park, Rio Grande do Sul, State are presented. The difference in species diversity among the habitats was proved through similarity tests. The twig was the habitat that has presented the greatest floristic differentiation and the branches were similar to the trunks. Lichen communities vary depending on habitat conditioned to the bark roughness, which changes according to the age of the substrate.
