CARACTERIZAÇÃO FLORÍSTICA E ESTRUTURAL DE UMA FLORESTA OMBRÓFILA DENSA ALTOMONTANA DO MORRO DO ANHANGAVA, QUATRO BARRAS – PR

Species composition and forest structure were studied at an Upper Montane Rain Forest, in the Southwest face of the Anhangava mountain (25o23'S and 49o00'W), at Quatro Barras, Parana, among 1.250 - 1.350 m of altitude. Species composition and forest structure were determined through a survey of twenty plots (5 x 10 m each) where all trees 10 cm or higher in girth at breast height (GBH) were measured and identified. The forest community showed high density (4.830 n/ha), low height (< 8 m) and it is composed of just one story. Only 24 species of 13 families were found denoting low diversity. Three species, at least, are endemic. From these 24 species only a few dominated the community. Myrtaceae was the more representative family, however Ilex microdonta Reissek an Aquifoliaceae presented the higher density (26%) and dominance index (46%).
