Le noisetier d’Afrique, Coula edulis Bail., produit des graines de grande valeur nutritive régulièrement collectées et commercialisées par les populations locales. Toutefois, certains aspects fondamentaux de son écologie, dont le potentiel de production, la dispersion et la prédation des fruits, demeurent inconnus, ce qui pourrait constituer un frein à sa valorisation. L’étude s’est déroulée au Gabon et s’est attachée à quantifier la production fruitière de l’espèce et à identifier les prédateurs et disperseurs des fruits. Trente-neuf collecteurs circulaires ont été installés sous les houppiers, les données récoltées (nombre et masse des fruits) étant ensuite mises en relation avec le diamètre. Par ailleurs, sept semenciers ont fait l’objet d’observations indirectes grâce à un dispositif de caméras-pièges. Les premières fructifications apparaissent sur les semenciers à partir de 12,3 cm de diamètre. Elle se produit de janvier à avril. Les quantités de fruits sont corrélées positivement au diamètre (r² = 0,493 ; p = 0,001). Dix espèces animales ont été observées aux pieds des arbres en fruits, leur rôle dans la dynamique de population de l’espèce est potentiellement important. [less ▲]

Non-timber forest product (NTFP) are of significant nutritional, economic and cultural importance for the people of central Africa. However, many products have not yet been the subject of scientific studies; such is the case of Coula edulis. Although very little is known about this species, it has many uses and its fruits are regulary eaten and marketed by various communities. Cultivation of this tree species remains however very limited, mainly because of the low germination potentiel of its seeds. Its wood, renowned for its termite resistance, is used locally for construction. Mechanical tests conducted on the timber have put its technological aptitudes to the fore; it has indeed the potential to become one of the most sought-after commercial species. As in the future, Coula edulis could be managed for its wood as well as its non-timber forest product, in-depth studies aiming at the sustainable development of this natural ressource need to be implemented.
