摘要：A floristic survey was conducted of woody species occurring in a 1.14ha forest fragment located in Campos do Jordão, SP, which were classified according to dispersion syndrome and ecological succession. Fifty-four woody species pertaining to 43 genera and 33 families were recorded, occurring on the edge, the interior, and in both habitats in the forest fragment. Zoochory was the most frequent species (31.37%), followed by anemochory (23.5%) and autochory (3.9%). The successional classification indicated the predominance of secondary species (44%) followed by pioneers (18%), as well as diverse species without characterization (38%) due to the lack of information regarding their regeneration strategies. Negative impacts of the fragmentation process acting in the region were probably determining factors in the floristic impoverishment and damage in the tropical montane forest fragment in intermediate of phase of regeneration. Despite the low number of species recorded, this fragment can be of great importance for the sustainability of the surrounding forest fragments if its role in the functional connectivity of the landscape is proven. In this forest fragment, woody species common to this kind mountain forests formation can still be found, demonstrating its function in the maintenance of threatened regional biodiversity.
