“…Widespread timber concessions granted to industries compete with agriculture, hunting, small-scale logging and, it has been suggested, with the gathering of non-timber forest products by local people who live in or near the forests (Tieguhong and Ndoye 2007;Guariguata et al 2010). FTA research on forest uses by men and women in dozens of villages in Cameroon, Gabon and the Democratic Republic of Congo (Tieguhong et al 2017) showed that local people depend on forest foods, including both plants and animals. Scientists analyzed the density and abundance of forest resources and found that extracting both industrial timber and forest foods from trees could be sustained from the same concession if users followed clear guidelines and negotiated agreements to reduce conflicts (Tieguhong et al 2017;Maukonen et al 2020).…”

“…En complément de l'efficacité de cette approche participative, la compagnie CFT (Compagnie forestière de transformation) (2015) préconise qu'une analyse des conflits d'usage potentiels soit entreprise village par village, au moment de la préparation des plans annuels d'exploitation, afin que des mesures de réduction de l'impact social soient prises, notamment en protégeant les arbres importants pour les populations locales. Tieguhong et al (2017) renchérissent sur la nécessité de disposer d'informations sur la disponibilité et l'accessibilité des espèces d'arbres à usages multiples, pour négocier un mode de gestion qui satisfasse à la fois les concessionnaires et les communautés locales. Ainsi, certaines populations de sapelli ou d'autres espèces de Entandrophragma de grande valeur commerciale présentes dans les terroirs villageois seraient à classer en zone de Haute Valeur de Conservation de type 5 s'agissant de « zones forestières fournissant aux communautés locales des ressources nécessaires à la satisfaction de leurs besoins élémentaires » .…”

Par la qualité de leur bois et leurs nombreux usages traditionnels, les espèces du genre Entandrophragma font l’objet d’une intense exploitation, susceptible de compromettre leur pérennité en l’absence de gestion durable. La présente étude dresse un état de la situation de cinq espèces commerciales principales de ce genre : Entandrophragma angolense, E. congoense (souvent assimilée par erreur à E. angolense), E. candollei, E. cylindricum et E. utile. Elle propose des pistes de recherche pour améliorer les stratégies de gestion durable au sein de ce genre. L’étude est principalement basée sur les données scientifiques (publications), économiques (statistiques de production et d’exportation) et juridiques (lois et réglementations), mais aussi sur les plans d’aménagement et les rapports d’inventaire. Les connaissances sur leur gestion sont encore fragmentaires alors qu’elles sont considérées comme vulnérables dans la liste rouge de l’UICN. La forte exploitation industrielle ou artisanale de ces espèces ne s’effectue pas toujours dans le respect d’un plan d’aménagement validé, ni de la durée minimum des rotations qui permettraient l’un et l’autre un taux de reconstitution pérennisant cette ressource. Leur gestion durable exige notamment le développement et le respect de mesures d’aménagement pour rendre leur exploitation renouvelable à long terme. Cette exploitation doit s’appuyer sur une gestion adéquate des peuplements naturels et sur le reboisement ainsi que sur des mesures de conservation. Les recherches à développer doivent intéresser leur vitesse de croissance face aux évolutions climatiques, l’évaluation de leurs stocks (production, biomasse, carbone), l’actualisation de leur distribution spatiale, l’amélioration de leur régénération naturelle, les processus de leur reproduction, leurs propriétés anatomiques et technologiques, autant de pistes pertinentes pour garantir la pérennité des espèces exploitables du genre Entandrophragma.

“…The African tropical forest plays a major role in the world, through its multiple ecosystem services (Makana et al, 2011;Fétéké et al, 2015;Tieguhong et al, 2017). However, it is under increasing pressure from shifting agriculture and timber extraction (Bourbier et al, 2013), especially for industrial purposes.…”

Description of the subject. Pericopsis elata (Fabaceae) is a long-lived light-demanding tree from African rain forests that produces timber of high economic value. Natural populations suffer from overexploitation and a deficit of natural regeneration. Plantations could increase its production and limit the pressure on natural forests. However, we lack knowledge on the influence of spacing and seed tree origin on tree growth to optimize plantation protocols. Objectives. This study evaluated the impact of sapling density and seed tree origin on the growth in diameter and height of P. elata plants, 20 months after plantation. Method. Seeds were collected on 19 mother trees in a 400 ha natural stand near Kisangani (DRC). In October 2017, seedlings were transplanted in a Nelder design plantation with three replicates, to compare sapling growth at 10 contrasting plant densities under full sun. Diameter and height increments of 540 plants were analyzed according to local competition and maternal origin using generalized additive models. Results. Twenty months after planting, height growth peaked at an intermediate density of 47,000 stems·ha-1 (165.6 ± 39.2 cm·year-1), while diameter growth peaked at a lower density of 4,200 stems·ha-1 (24.6 ± 8.3 mm·year-1). The maternal origin of saplings affected their growth, the coefficients of variation among mother trees reaching 7.6% and 6.4% for diameter and height increments, respectively. The initial diameter affected positively diameter growth while the initial height did not influence height growth. Conclusions. The Nelder design proved useful to assess how plant growth depends both on spacing and genetic factors.
