RESUMO

Resumo: O objetivo deste trabalho foi avaliar a incidência e a intensidade de danos causados por bovinos ao mogno-africano (Khaya grandifoliola) e a vulnerabilidade desta espécie em sistema silvipastoril. As árvores foram plantadas em linhas simples, arranjadas em 20x2 m. No terceiro ano, os bovinos foram introduzidos na área. Foram estabelecidas três classes de intensidade de danos: baixa, média e alta. Os danos causados às cascas das árvores foram os de maior incidência, seguidos por danos causados ao lenho. A espécie é vulnerável à mastigação da casca por bovinos, com danos de média e alta intensidades.Abstract: The objective of this work was to evaluate the incidence and intensity of damages caused by cattle to African mahogany (Khaya grandifoliola) and this species vulnerability in the silvipastural system. The trees were planted in single lines, in a 20x2 m arrangement. In the third year, cattle were introduced in the area. Three classes of damage intensity were established: low, medium, and high. Damages to tree barks showed the highest incidence, followed by damages to wood. The species is vulnerable to bark chewing by cattle, with damages of medium and high intensities.
