| Abstract | Floristic analysis and phytosociology of trees from the Mixed Ombrophyllous Forest in the Forest Reserve Embrapa/Epagri in Cacador, SC, Brazil. Composition, diversity, structure and stem quality of trees were determined for the Forest Reserve Emb rapa/Epagri (RFEE), Cacador (SC), which consists of a 1,194 ha Mixed Ombrophyllous Forest patch. In forty-eight 0.05 ha sample plots and eight 0.025 sample plots, 1,225 trees with DBH grea ter than 10 cm were identified and measured. Phytosociological indices were also calculated, inc luding the Extended Importance Value (EIV). Seventy-one tree species, 33 families and 54 genera were found on the area. Species richness concentrated on Myrtaceae, Lauraceae, Fabaceae, Flacourtiaceae, Asteraceae, Aquifoliaceae and Sapindaceae families, which together accounted for 52.8% of the total number of species. Average density was 484 trees/ha and average DBH and total height were 23.9 cm and 11.7 m, respectively. Estimated basal area was 31.4 m 2 /ha. According to the EIV, the ten main tree specie s of the RFEE were: Cupania vernalis, Araucaria angustifolia, Ocotea po rosa, Capsicodendron dinisii, Prunus brasiliensis, Ocotea pulchella, Clethra scabra, Mat ayba elaeagnoides, Ocotea puberula and Sebastiania commersoniana . The typical floristic pattern of the Mixed Ombrop hyllous Forest is similar to the one observed in the RFEE. The Shannon Diversity Index was equal to 3.586 nats/ind. for species and 2.827 nats/ind. for families. |
