In Lower Casamance, farmers deliberately keep certain woody species in their fields to increase their crop yields and generate additional income. The objective of this study is to contribute to a better understanding of the state of agroforestry parks in Lower Casamance. To achieve this objective, vegetation surveys were carried out. Thus, a square plot of 2500 m² (50m x 50m) was installed in the fields of each of the 99 farmers selected in the sample, for a total of 99 plots. This sample is distributed among the different municipalities of the arrondissement in proportion to their demographic weight, ie 18; 14; 14; 53 plots respectively in the municipalities of Coubalan, Ouonck, Niamone and Tenghory. The agroforestry parks in the district of Tenghory have a specific richness of 64 woody species divided into 53 genera and 20 botanical families. The observed density of trees is 21.8 feet / ha, the basal area is 3.3 m² / ha with a coverage rate of 13.7%. The height class structure of the woody stand reveals a predominance of individuals ≥ 10 m in height (50.5%). The diameter class [5-25] is the best represented with 45.8% of the individuals. These results thus constitute a source of useful information for the rational management of agroforestry parks in the district of Tenghory.
