Tree composition of a seasonal semideciduous forest in Pirenópolis, Goiás state

Abstract

The Seasonal Semideciduous Forest is one of the most threatened Brazilian ecosystems. Therefore, to conduct forest mensuration studies in these areas is of vital importance to provide data for development of management strategies and they are also important for recovery of degraded areas. In view of this, the objective was to study the flora of a fragment of 10 ha of semideciduous forest at Raio de Sol farm (15º 45’ 54’’ S and 49º 04’ 03’’ W) in Pirenópolis municipality, in the State of Goiás. It is inserted into the bioregion called Cerrado EcoMuseum. Ten sample plots (20 X 20 m) were surveyed. In these plots all living trees with 5 cm diameter at 1.30 m above ground (DBH) were measured. 742 individuals belonging to 83 species, 67 genera, and 36 families were registered. The richest families in number of species were Fabaceae, Myrtaceae, Rubiaceae, Chrysobalanaceae and Apocynaceae, which contributed 48% of total species found.
