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.
