ABSTRACT

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.
