We performed a phytosociological study on an altitudinal gradient in Lauráceas State Park (Parque Estadual das Lauráceas/PR), aiming to describe the Montane Atlantic Rain Forest, to verify the importance of Lauraceae, and to evaluate the communities’ successional stage. We distributed survey units (2,000 m2 quadrats) along an altitudinal gradient and surveyed all individuals with DBH ≥ 10 cm, which composed the arboreal component. In smaller quadrats (250 m2), we surveyed regeneration individuals. The community at 800 and 900 m a.s.l. shows typical characteristics of Montane forest in an advanced successional stage, and the abundance of Ocotea catharinensis is its main indicator. At 1,000 and 1,100 m a.s.l., the forest is characterized as Montane with short stature in an advanced successional stage, with the occurrence of typical upper montane species such as O. porosa and O. vaccinioides.
