Abstract

This study aimed to investigate the regeneration of species stricto sensu of the Cerrado used in extractivism in areas of settlements: Margarida Alves, Corixo and Bom Jardim/Furna São José, in the Southwest region of Mato Grosso, Brazil. The analysis was based on floristic and phytosociological data collection in 30 installments, measuring 20 x 50 m, in the period from February to July 2012. The inclusion criteria was the circumference at breast height ≥ 15 cm and height ≥ 3 m. At the Margarida Alves settlement, the babaçu (Attalea speciosa) was the species with higher importance value index (IVI), 92.00%, in Corixo settlement, it was the pequi (Caryocar brasiliense), with IVI=40.65%; and in Bom Jardim/Furna São José, the cumbaru (Dipteryx alata) was the second species with higher IVI (26.24%). The R² values for the relationship of the individuals on the circumference and height resulted in low values for the species mentioned, so it has not been demonstrated the J-inverted standard in most histograms graphs indicating poor regeneration, which can, in the future, compromise the extractive activity in the settlements.
