A study was carried out in the Mounts Mandara to assess the diversity of edible plant species, to identify the use of the edible products, and to determine their socioeconomic value. Interviews of a sampling population were conducted randomly in 5 zones with 5 villages each and in rural and urban markets; a sample of 1020 persons was interviewed to evaluate and quantify the various products and determine their flows. The results showed that the edible plant products used in the area were: fruits, leaves, flowers, seeds, tubers, roots, barks and stems. These products were harvested from 61 plant species belonging to 29 families in which 54 species were fruit trees, 11 species produced leaves and / or flowers, 4 species produced seeds. The total annual quantity of products harvested was 1080.9 t in which: fruit (725.62 t); leaves (97.5 t), flowers (1.96 t), and seeds (255.82 t). The seeds of Parkia biglobosa were the most useful part by the populations of Mounts Mandara making "dawa-dawa" some traditional aromatic for a sauce. Exploited products were an important source of food and income for the people. Annually, exploited products generated at whole of 60 783 975 F CFA. The fruits were sold for 17 542 375 F CFA, the seeds yielded 36 676 900 F CFA, the contribution of the leaves was 5 452 820 F CFA and that of the flowers was 724880 F CFA, "dawa-dawa" brought, very popular, bring in a modest sum of 787 000 F CFA. Local people were developing interest in exploiting different bush products. The exploitation activities of the various products were intensifying; the requested species must be domestication to ensure the sustainable management.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
