Abstract

This study aims at identifying the effect of P. reticulatum on the vegetation regeneration dynamic in Sudanian fallows of Burkina Faso. Two fallows of about twenty years old have been considered. The point quadrat method was used for herbaceous inventory. Aboveground biomass has been estimated. Moreover, effect of P. reticulatum on the regeneration of others woody species has been studied under, at the limit and out of the shrub canopy. In north Sudanian zone, inventory recorded 39 herbaceous species of which 23 species under the canopy and 16 in open grassland, distributed in 12 families and 22 genera. In south Sudanian zone, species diversity is 41 species from which 23 under the canopy and 18 out of, spread in 16 families and 26 genera. Species higher than 80 cm have been observed only under P. reticulatum canopy in south and north Sudanian zone. In addition, no species of striga met in open sunlight has been observed under the shrub canopy. East and West directions recorded the important proportions of species with individuals belonging to the stratum superior to 100 cm (3.13 and 4.81 % in north direction, 1.47 and 1.73% in south directions).
