%X The main objective of the study was to investigate the diversity of the woody stratum of the vegetation in intercommunity rangelands in the department of Koungheul based on an ecological inventory using vegetation surveys. The results indicate a rich flora of 70 species divided into 54 genera and 27 families where <em>Ceasalpiniaceae</em> and <em>Rubiaceae</em> are dominant (5 genera each). They are followed by <em>Combretaceae</em> and <em>Euphorbiacea</em> (4 genera each) and by <em>Capparaceae</em>, <em>Fabaceae</em> and <em>Mimosaceae</em> (3 genera for each family). But at the specific level, it is the <em>Combretaceae</em> which dominates with 10 species and <em>Rubiaceae</em> (7 species). It is more representative at the level of the rural community of Lour Esacale. The different values of vegetation parameters from one site to another indicate variability in community rangeland management practices. The woody stand, dominated by small <em>Combretaceae</em>, shows a relatively stable level of organization with an average equitability of about 45% for the two rural communities studied. Species such as <em>Cordyla pinnata</em>, <em>Sclerocarya birrea</em>, <em>Adansonia digitata and Sterculia setigera</em> contributed strongly to the basal and aerial cover of the overall stand. The regeneration of the stand is very good (about 85% on average) but it represents very few species, especially of the <em>Combretaceae</em> family. This shows a tendency to a progressive loss of species richness in the woody stratum.
