Lianas are known as forest parasites, although they are major components structurally and floristically of natural forests. The aim of this study was to research liana ecology and its effects on growth and production of Angico-Vermelho. Field procedures were realized in one hectare of natural forest and 50 individual trees. Were found 23 species in the liana community, that strongly dominated by Senegalia tucumanensis. Scramblers and tendril climbers showed a greater capacity of sprouting, being more resistant to liana cutting. Angico-Vermelho has more lianas around it than does the overall forest. Above-ground competiton, measured by COI (Crown Occupancy Index), negatively influenced crown development. Liana basal area helped to explain basal area increment variation in Angico-Vermelho as the overall model explained almost 80% of total variation. Angico-Vermelho has great exploration potential in natural forests due to fast growth, wood quality and carbon sequestration ability. It is recommended, as a silvicultural treatment, liana cutting in trees with less than 20 centimeters of diameter, otherwise in trees with more the 25% of the crown occupied by lianas.
