Abstract
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.
Highlights
In West Africa, agriculture is marked by a traditional landuse system, where trees dot the cultivated or recently ploughed fields called "agroforestry parks" [1]
In Lower Casamance, there are very few studies on the state of agroforestry parks [11]. It is in this context that this work is carried out with the aim of establishing the floristic and structural characteristics of the woody vegetation of the agroforestry parks in the Tenghory district
The study of the agroforestry parks in the Tenghory district identified sixty-four (64) woody species divided into fifty-three (53) genera and 20 botanical families
Summary
In West Africa, agriculture is marked by a traditional landuse system, where trees dot the cultivated or recently ploughed fields called "agroforestry parks" [1]. In these fields, farmers keep the trees that are not very troublesome or useful and sometimes introduce new species that are part of the cropping system [2]. Farmers keep the trees that are not very troublesome or useful and sometimes introduce new species that are part of the cropping system [2] These parks are exploited by the populations, who earn additional income from tree products. It is in this context that this work is carried out with the aim of establishing the floristic and structural characteristics of the woody vegetation of the agroforestry parks in the Tenghory district
