| description | ABSTRACT
The African savannah elephant (Loxodonta africana) is an ecosystem engineer essential in determining the structure and vegetation abundance in mesic dry protected areas such as the Mana Pools National Park (MNP) in Zimbabwe. Understanding the interactions between elephants and vegetation structure is essential for effective conservation and management of savannah ecosystems. Conservation efforts often aim to balance elephant populations with the carrying capacity of their habitats to ensure the sustainability of both flora and fauna within protected areas. Therefore understanding how African savannah elephants influence vegetation structure, abundance and damage is critical for adaptive ecosystem management and wildlife conservation in mesic savannah ecosystems. This study assessed: (i) vegetation structure, (ii) abundance and (iii) evidence of elephant‐induced vegetation damage near a distance gradient to water points in MNP. A generalised linear model (GLM) was used to investigate the relationship between vegetation aspects that is structure, abundance and evidence of damage with distance from water sources. In the mesic protected MNP where African savannah elephants predominate, the modelled vegetation shape, abundance and damage exhibit spatial differences on a distant gradient towards water sources (χ2, p |

Résumé
L’éléphant de savane africaine (Loxodonta africana) est un ingénieur des écosystèmes, essentiel pour déterminer la structure et l’abondance de la végétation dans les zones protégées mésiques sèches telles que le parc national de Mana Pools (MNP) au Zimbabwe. La compréhension des interactions entre les éléphants et la structure de la végétation est essentiel pour une conservation et une gestion efficaces des écosystèmes de savane.
