Diversity and successional index of cerrado sensu stricto at the UEG campus

This work assessed the composition, diversity, successional stage and distribution of species in 6 ha of cerrado at the UEG campus. Thirty plots 100m² each and dbs higher or equal to 5 cm were used. Of 515 specimens distributed in 20 families, 28 genus and 46 species were sampled. Greater richness was observed in Leguminosae, Vochysiaceae and Malpighiaceae. The species Qualea grandiflora, Byrsonima crassa, Erytroxylum tortuosum, Qualea parviflora and Miconia ferruginata presented higher VIs. Diversity index (H¢ = 1.35) was lower than the other values described for the cerrado. This could be a consequence of the abundance of species such as Q. grandiflora and B. crasssa as well as of local anthropogenic interferences, including fire. The value of successional index (SI = 2.3) indicates an intermediary stage of succession. The community fitted only to the normal-log model, which, according to the literature, could be a consequence of the abundance proportion of the dominant, intermediary and rare species in the community.
