Natural regeneration pattern of the wild custard-apple, Annona senegalensis Pers. in the semi-arid area of Burkina Faso, West Africa

Annona senegalensis Pers. (Annonaceae) is a multipurpose shrub species, but threatened in Burkina Faso. Therefore, understanding its natural regeneration challenge for the sustainable management of species resources. Our study examines potentials A. across two phytogeographic zones. The structure Weibull showed that distribution individuals based on height classes, was inverse J-shaped reveals relative predominance small size classes. A log-linear adjustment test Weibull’s confirmed observed and were not conformed (p<0.0001). generalized linear model (GLM) an ANOVA density significantly higher south-sudanian zone. stratum 1 2.46 times north-sudanian than Green Index (GI) spatial random (GI=0). reproduces mainly by seed germination. faces difficult regeneration, accentuated climate pejoration stronger anthropogenic pressure. suggests assisted which should contribute to better conservation species. Key words: senegalensis, ontogenetic stage, population structure, distribution, mechanism.
