In Burkina Faso, rural livestock farmers in arid and semi-arid areas rely heavily on woody plant resources such as Acacia nilotica and Acacia raddiana to satisfy the needs of small ruminant rearing. The assessment of the availability and the use of these two species are therefore essential to better manage them sustainably for their preservation. The survey carried out in the area showed that the questioned farmers exploited the leaves and pods of the two Acacia for the needs of the ruminants. 100% of the farmers exploit A. raddiana only for the feeding of small ruminants. However, A. nilotica was exploited for animal feed and health. The most commonly reported treatments are Foot and Mouth Disease (98.7%) followed by diarrhea (73.7%) and foot wounds (51.2%). In order to compare the results of the survey, a botanical inventory was carried out in the area and the results showed that A. raddiana is more available compared to A. nilotica. Also, other local species such as Faidherbia albida, Acacia senegal, Balanites aegyptiaca and Acacia siberiana are also exploited for the needs of small ruminant rearing in the study area. The most important constraints were excessive cutting, drought and overexploitation that negatively impact their survival. Data on these constraints provide the basis for a campaign to raise awareness among herders' communities to preserve these plants to sustainably improve the productivity of small ruminants and consequently farmer’s income.
