As part of the Biological Diversity Information Exchange Center, the OBPE, through the Research Program, Information Exchange, Awareness and Conservation of Biodiversity in Burundi, under the funding of the IRSNB, has the mission of strengthening the Herbarium in accordance with International standards. In this context, samples that were already in the folders were classified according to families and species. Given that some samples were in Poor condition, this report describes the work of their classification carried out by a team made up of Mr. Nyabenda Mathias and Ms. Manirakiza Odette.
