Population structure and regeneration status of Sclerocarya birrea (A. Rich.) Hochst. under different land use types in Burkina Faso, West Africa

Sclerocarya birrea is a keystone species in the diet, traditions, and culture of local communities in West Africa. This study assessed the impact of land use type on the woody’s diversity, regeneration pattern and population structure of Sclerocarya birrea stands to implement a strong management scheme. Data were collected from 150 plots across field, fallow, and forest in Burkina Faso. Regeneration was recorded as seedling, suckers and coppices in diameter height classes. Hill diversity indices were used to determine the effect of land use in stands diversity. Weibull theoretical model was applied to analyze size classes distribution. Land use significantly influenced Sclerocarya birrea stands diversity and structure, with the lowest diversity recorded in field. The largest and tallest individuals were recorded in field while fallow and forest had the maximum tree density. Seedling is the most common regeneration type, especially with higher density in flied. However, diameter size classes distribution revealed unstable structure population in field while fallow and forest were more stable. This study highlights the need to improve juvenile management and promote low-cost nursery techniques for Sclerocarya birrea . Famer’s should support seedlings protection in agroforestry systems for better sustainable use and long-term preservation of the species.
