Resumo
In the Cerrado biome of Brazil, savannas and dry forests are intimately
linked and form mosaics. These forests are composed of species of high commercial
value, well accepted in the timber market, which causes intensive deforestation on the
remaining vegetation. Thus, the management of these forests is an important alternative
to reduce deforestation in the remaining vegetation. The objective of this study was to
analyze the response of tree species in relation to silvicultural treatments of competition
and liana cutting in a semi-deciduous forest in Central Brazil. The results showed that
community basal area increased 24% over 4.8 years and the median periodic annual
increment in diameter was about 20% higher in plots with silvicultural treatments: 2.9
mm.yr -1 in the control compared to 3.2 mm.yr -1 to 3.6 mm.yr -1 between treatments.
This study demonstrated that it is possible to increase the rates of radial growth through
silvicultural techniques.
