En 2011, Nature+ a rencontré ses missions, notamment : en mettant en oeuvre deux projets de foresterie communautaire financés par des bailleurs internationaux ; en participant à la gestion durable de près de 2 millions d’hectares de forêts denses humides tropicales grâce à nos collaborations avec des sociétés forestières engagées dans les processus de certification FSC ; en accueillant dans nos divers projets 12 étudiants en fin de cursus universitaire ainsi que 8 doctorants. 7 universités différentes ont ainsi reçu un appui administratif, technique et scientifique de Nature+.

The wildlife populations of northern Central African Republic (CAR) have long suffered intense uncontrolled hunting. Socio-political turmoil in northern CAR that started in 2002 resulted in a rebellion in 2006. An aerial sample count was carried out in northern CAR after the cease-fire to assess the impact of this troubled period on wildlife. The survey was flown at the end of the dry season in February-March 2010. It covered a landscape complex of 95 000 km² comprising national parks, hunting reserves and community hunting areas. Comparison with earlier surveys reveal a dramatic decline of wildlife: the numbers of large mammals fell by 94% in 30 years, probably due to poaching, loss of habitat and diseases brought by illegal movements of cattle. Elephant (Loxodonta africana), reduncini and topi (Damaliscus lunatus) populations showed the greatest decline (each over 90%). Other species declined by 70 to 80% during the same period. The future of the rest of the wildlife in this area is dark without a strong commitment to provide adequate funding and quickly implement determined field management. Reinforced cooperation with neighbouring Chad and Sudan is required since they are facing similar problems. [less ▲]

The management of wood energy has become a major concern for the international community and is the focus of debates in Central Africa. The Makala Project, funded by the EU, fits within this context with the objective of securing the supply of wood energy to urban centers. Over the past three years, various forest resources management techniques have been designed and an assessment of the wood energy sector has been conducted in Kinshasa. Various technical itineraries have been proposed for the management of areas dedicated to thesupply of wood energy at various levels, from the farming plot to the village land, and from the individual approach to the collective approach. This article provides a snapshot of the activities developed by the Makala Project to improve the management of periurban forest ecosystems and to secure the supply in wood energy. [less ▲]

The present study consists of analyzing the raw data collected from the annual line-transect foot count of medium-sized ungulates, carried out at the Nazinga Game Ranch (NGR), Burkina Faso (Western Africa), in both 2001 and 2010. The annual census focused on the seven main medium-sized ungulates, namely (in alphabetical order), the Bushbuck (Tragelaphus scriptus), the Common Warthog (Phacochoerus africanus), the Defassa Waterbuck (Kobus ellipsiprymnus), the Grimm’s Duiker (Sylvicapra grimmia), the Oribi (Ourebia ourebi), the Roan Antelope (Hippotragus equinus) and the Western Hartebeest (Alcelaphus buselaphus). The census also focused on illegal anthropogenic activities. The wildlife populations were quantitatively analyzed through an estimation of their absolute density via the distance sampling method and through their evolution over the last decade using two relative density indexes, namely the Kilometric Abundance Index (KAI) and a spatial distribution index. These indexes were also used to measure the evolution of illegal activities over the same period. Both the wildlife observations and the anthropogenic observations were mapped using the Kernel method. Following an increasing trend in their population between 2001 and 2010, both the Roan Antelope and the Western Hartebeest reached an estimated density of 4.7 individuals per km², while the Defassa Waterbuck reached 2.4 individuals per km². Following an inverse trend over the same period, the Bushbuck, the Grimm’s Duiker and the Oribi reached an estimated density of 0.4 individuals per km². As for the Common Warthog, its estimated density of 2.5 individuals per km² seemed to remain unchanged during that decade. A comparison between wildlife observations and anthropogenic observations reveals a high decrease in animal densities in the north, east and west peripheral borders of the NGR and a flagrant extension of the proportion of the ranch being subjected to illegal activities (poaching, cattle herding, etc.).

The comparison of some elephants count methods – aerial sampling count, aerial total count and direct foot count – has been presented through surveys’ study cases implemented in Benin, Burkina Faso and Niger. We compare them in terms of effort and cost to survey an area (sampling efficiency), efficiency in data collection (detection efficiency) as well as accuracy and precision. Aerial sampling count returns low sampling and detection efficiency and very low precision and accuracy figures when counting elephants populations below 0.5 elephant.km-2. Precision can partly be improved by stratification. Direct foot count returns the best sampling and detection efficiency but insufficient data number to produce reliable estimates. Therefore some authors often produced no results for elephants. Aerial total count is a costly method in absolute value. It requires important logistic and no measure of error is possible. However it provides relatively good sampling and detection efficiency as well as relatively accurate figures appreciated by wildlife managers if technical requirements are respected. Aerial total count could be recommended to survey small population of West African elephants each 3 to 5 years to minimize yearly count costs. [less ▲]

Community forests, pillars of participatory forest management in Central Africa, have been incorporated into the Cameroon VPA, which is to come into force by the end of 2012. However, a recent study suggests that this integration might disturb the good implementation of the VPA. In consequence, community forests indirectly threaten the export of all Cameroonian timber.

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 ▲]
