Nowadays, natural resources management based on modern methods of preservation has shown its limits, forcing managers to combine local practices and knowledge. This work based on ethnobotanical investigation and phytosociological surveys, has been undertaken in order to show the importance of sacred woodlands in biodiversity conservation and to provide reliable data on the flora and vegetation of sacred woodlands. The study was carried out in the four phytogeographical areas of Burkina Faso. Investigation allowed identifying 1206 sacred woodlands of which 403 have been the subject of extensive inventory to assess the level of biodiversity. 417 phytosociological surveys were carried out as part of floristic inventory. The data was analyzed by multivariate method using CAP, EXCEL 2010 and JMP9 software. The results of the floristic analysis show an important floristic richness of the sacred woodlands with 470 species belonging to 284 genera and 74 families, which represent 24. 54% of the national flora. The dominant species in sacred woodlands are mainly phanerophytes and therophytes. Chorology shows Sudanese species are predominant, followed by pantropical species and Sudano-Zanbesian species in almost all the four phytogeographical areas of Burkina Faso. Some very rare endangered species in surrounding areas have found in the sacred woodlands. This shows the need to take actions to safeguard biological diversity of sacred woodlands.
