SummaryFour areas of the Acacia seyal zone of the Waza National Park, Cameroon, were sampled by means of line transects to assess damage to trees caused by elephants. A total of 1742 trees was examined of which 72% were undamaged, 17% less than three‐quarters damaged and 11% were dead. Most of the damaged and dead trees were mature. Of the living trees, 42% were in the recruitment class, 34% were mature and 23% were in the regeneration class. It is concluded that elephant damage to Acacia trees is not serious enough to warrant management interference.RésuméLes effets du broutage par les éléphants de l'Acacia seyal dans le Parc National Waza, au Cameroun.
