A phytosociological survey was carried out in the Grota Funda
Municipal Park, Atibaia Municipality, São Paulo State (45045' - 460 45'W and
230 10' - 230 15'S). The region is mountainous, occurring from 900 to 1400 meters
above sea leveI. A total of 42 quadrats, each 10 x 10m, were plotted along an altitudinal
gradient. In each sample, aD trees with perimeter ;;:: 15cm at breast height
were recorded. The study was done from April 1987 to November 1988. In the
phytosociological survey, 1076 individuals were recorded, belonging to 52 families,
92 genera and 134 species. Phytosociological parameters of frequency (absolute
and relative), density (absolute and relative), dominance (absolute and relative),
importance value index and cover index are presented for alI species. The results
show that the most important families are Myrtaceae, Lauraceae, Euphorbiaceae,
Apocynaceae and Mirnosaceae and the most important species are Machaerium
nictitans, Aspidosperma olivaceum, Anadenanthera colubrina, Sebastiania
edwaUiana, Guapira opposita and Styrax polúii. The sernideciduous, moutain forest
is unique and represents a kind of forest that occurs only in regions above
lOOOm, with floristic and phytosociological particularities.
