COMPOSIÇÃO FLORÍSTICA E ESTRUTURA DE UM FRAGMENTO DE FLORESTA ESTACIONAL SEMIDECIDUAL ALUVIAL EM VIÇOSA (MG)

Floristic composition and structure of a fragment o f alluvial Semi-deciduous Tropical Forest in Vicosa (MG). This study was developed in a fragment of riparian forest settled in Fazenda Sao Luiz, Vicosa (MG). The floristic composition and forest s tructure was investigated through a census. All individuals with diameter at breast height (DBH) eq ual to or greater than 3 cm were evaluated. A total of 375 individuals distributed in 58 species, 46 ge nera and 25 families were surveyed in 0,5 ha. The Shannon diversity index (H’) was 3.41. The species with the highest Cover Value (CV) were Cecropia glaziovii , Nectandra reticulata , Anadenanthera colubrina . This forest remnant is composed mostly by initial secondary species characterizing it in a pioneer seral stage and with conservation value extending to the protection of the associated water resources, acting as a natural barrier to th e sedimentation of the water course.
