Abstract

The objective of the study was to investigate changes in the woody plant community in a four-year period. It was established 50 permanent plots of 10 × 10 m and all individuals with diameter above ground 30 cm (DAG 30 cm) > 5 cm were sampled in 2002 and 2006. In the inventory of January 2002, were found 945 individuals belonging to 77 species, 65 genera and 35 families and in January 2006, were 1,106 individuals, 80 species, 66 genera and 36 families. Community species diversity and diameter structure did not change within the period. Mortality rates (4.01% year-1) and basal area losses (0.68% year-1) were offset by recruitment (6.67% year-1) and gain (2.26% year-1), indicating community maintenance as stable apparently. The periodic annual increment (PAI) of the community was 0.31 cm year-1, being overcome by the PAI of Euplassa inaequalis, Kielmeyera rubriflora and Byrsonima coccolobifolia (0.72, 0.49 and 0.47 cm year-1, respectively), indicating the growth potential of such species as important for recovery strategies on degraded areas. The absence of fire during the study period may have been the main factor behind the dynamics of the vegetation of the studied cerrado, favoring the establishment of some woody species and providing increase in density and biomass.
