Since prehistoric times, Burundians have lived in the forest. They have always considered the forest to be an inexhaustible resource “gift from God”. This consideration came from the fact that man was interested in an immense indigenous resource that provided him with all the necessary living conditions. Socio-economic and cultural needs were met from the forest. But humans have always believed that indigenous plant resources were inexhaustible. The overall objective of this work is to establish traditional agroforestry practices and their socio-cultural contribution in Burundi.

Our work consisted of a pre-survey and a survey itself carried out among the operators of the Kinyinya commune in RUYIGI province. The investigation was carried out on both indigenous and exotic plant species of economic, ecological and especially socio-cultural interests found in farms in our study area.

To carry out this work, the method used consisted of:

• Focus on the place where the heterogeneity and abundance of plant species are visible;
• Delimit an area of one hectare from the area to be explored;
• Go from one tree to another to measure the circumference of the tree at human chest height;
• Harvest the species found to identify them in the herbarium of the Burundian Office for Environmental Protection (OBPE).

During the harvest, two samples of the same species were collected each time. Species identification was carried out at the OBPE herbarium.
