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 ▲]

Precipitous declines in Africa’s native fauna and flora are recognized, but few comprehensive records of these changes have been compiled. Here, we present population trends for African elephants in the 6,213,000 km2 Sudano-Sahelian range of West and Central Africa assessed through the analysis of aerial and ground surveys conducted over the past 4 decades. These surveys are focused on the best protected areas in the region, and therefore represent the best case scenario for the northern savanna elephants. A minimum of 7,745 elephants currently inhabit the entire region, representing a minimum decline of 50% from estimates four decades ago for these protected areas. Most of the historic range is now devoid of elephants and, therefore, was not surveyed. Of the 23 surveyed elephant populations, half are estimated to number less than 200 individuals. Historically, most populations numbering less than 200 individuals in the region were extirpated within a few decades. Declines differed by region, with Central African populations experiencing much higher declines (276%) than those in West Africa (233%). As a result, elephants in West Africa now account for 86% of the total surveyed. Range wide, two refuge zones retain elephants, one in West and the other in Central Africa. These zones are separated by a large distance (,900 km) of high density human land use, suggesting connectivity between the regions is permanently cut. Within each zone, however, sporadic contacts between populations remain. Retaining such connectivity should be a high priority for conservation of elephants in this region. Specific corridors designed to reduce the isolation of the surveyed populations are proposed. The strong commitment of governments, effective law enforcement to control the illegal ivory trade and the involvement of local communities and private partners are all critical to securing the future of elephants inhabiting Africa’s northern savannas.

The consumption of wildlife meat is an important source of animal protein for rural and urban population in Congo. A survey on bushmeat trade was undertaken in 21 municipal markets during four weeks, in Brazzaville. The objective of this study was to define the traders’ profile and to evaluate the quantities of games and meat merchandised on the municipal markets. The study methodology combined two approaches: a quantitative one using a questionnaire as principal tool for collecting data, and a qualitative one associating informal survey methods via individual or group interviews. The results showed that women were the most involved in this trade (52%). Markets trader’s monthly income was estimated at 210,428 (US$420) ± 49,128 (US$98,256) FCFA. On average, the bushmeat traders’ were 39 ± 10 years old and 69% of them attended the two levels of secondary education. During four weeks, 3,711 animal carcasses were recorded on the 21 surveyed markets, representing almost 35,790 kg of biomass. Overall, 35 animal species were identified, including 9 the hunting of which was prohibited. The mammals constituted 93.8% of total number of hunted animals, with three dominant orders as the artiodactyls (49.2%), the rodents (22.6%) and the primates (17.7%), of which the Cephalophus, the Potamochoerus, the Atherurus and the Cercopithecus were the most represented. It was also noticed that trapping, an activity which leads to great losses, becomes very important, followed by be helpful alternatives to meet Congolese demand for bushmeat. For a sustainable management of the Congo’s faunic resources, this study suggests the introduction gun-hunting. The Congo-Ocean Railway and the National Road n°2 were used regularly in the transportation of game, to a 72% level. The district of Niari, Lekoumou, Sangha and Pool were the main sources of supply. At the present time, the meat quantities offered in Brazzaville markets don’t seem to be reduced because hunting areas extend always further, often to the detriment of protected areas. Despite the fact that such business squarely growths and shows evidence of overexploitation, activities promoting game farming and breeding of domestic species, in Brazzaville suburbs, are needed to mitigate the impact of bushmeat trade.

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.

La faune sauvage dans la Réserve de Biosphère de la Mare aux Hippopotames du Burkina Faso est très peu connue. Cette étude vise à inventorier les différentes espèces de mammifères sauvages et à recenser les activités de braconnage rencontrées dans cette réserve. Des dénombrements pédestres ont été réalisés en 2004, 2005, 2006 et 2007 suivant la méthode de transect linéaire à largeur variable. Ils ont consisté à suivre l’évolution de l’effectif des mammifères sauvages selon les contacts et les indices de présence ainsi que les activités de braconnage dans la réserve. 24 espèces de mammifères dont les patas (Erythrocebus patas), les babouins (Papio anubis), les éléphants (Loxodonta africana), les hippotragues (Hippotragus equinus), les phacochères (Phacochoerus africanus) et les civettes (Civettictis civetta) ont été recensées dans la réserve. Les contacts avec ces mammifères sont passés de 17 en 2004 à 28 contacts en 2007 pour un effectif de 94 individus toutes espèces confondues. Les activités de braconnage ont connu une baisse d’intensité entre 2005 et 2007 car le taux de braconnage s’est réduit de 58,4%. L’accroissement de l’effectif des espèces de mammifères et la diminution du braconnage peuvent s’expliquer par la surveillance continue de la réserve. [less ▲]
