Faidherbia albida (Del.) A. Chev. is a key agroforestry parklands species providing provisioning and regulating ecosystem services to people. Therefore, sustainable management and conservation of the species populations are great challenges on its distribution area. However, the species response to spatial variability of ecological conditions is poorly addressed, limiting its management and conservation. The objectives of this study were to: (i) assess the population status of F. albida along climate gradient in Burkina Faso and (ii) determine the effects of biotic and abiotic variables on population status and morphological traits of the species. Data were collected in 99 plots equally distributed in three climatic zones by focusing on biotic data in the plots (tree diversity and density, morphological traits of F. albida and all adult trees) and abiotic data (climate variables and elevation). The results showed that tree density and morphological traits of F. albida are significantly influenced (P
