La chasse est une activité importante pour les communautés proches des réserves de faunes malgré ses impacts négatifs sur les espèces sauvages. Durant un an et demi, un suivi quotidien a été mené aux côtés des chasseurs pendant 203 parties de chasse dans la zone d'étude. L'objectif de cette étude était de recenser les espèces chassées, d'analyser les différents lieux des prélèvements et d'évaluer la pression subie par la faune. L'utilisation des Modèles Linéaires Généralisés réalisés avec le logiciel R 3.4.1 ont permis le traitement des données des espèces prélevées. Au total, 2712 gibiers appartenant à 09 ordres d'animaux et 34 espèces ont été recensés parmi les prélèvements. Les espèces les plus abattues étaient des espèces de petites tailles comme Lepus crawashayi (31,12 %), Francolinus bicalcaratus (29,09 %) et Thryonomys swinderianus (10,88 %). La plupart des gibiers sont abattus dans les champs (53,28%) et les jachères (29,17%) et sur les affleurements rocheux (3,32%) et quelques-uns sont prélevés à l'intérieur de la savane protégée (1,29%). Les prélèvements sont non sélectifs, d'où des atteintes à la biodiversité faunique. Cette pression se manifeste aussi par la présence des espèces menacées dans les prélèvements , inscrites sur la liste rouge de l'UICN, comme l'Ourebie (Ourebia ourebia) , une espèce vulnérable (VU) et l'Outarde de Denham (Neotis denhami), une autre espèce en danger critique (CR). Les espèces prélevées sont des espèces résilientes de petites tailles qui résistent à la pression de la chasse pour le moment, mais, avec l'augmentation de la population, cette chasse ne sera plus soutenable. AbstractHunting is an important activity for communities close to wildlife reserves, despite its negative impacts on wildlife. For one and a half day, daily monitoring was conducted alongside the hunters during 203 hunting parties in the study area. This paper focuses on identifying the species hunted, to analyze the different sampling sites, and to evaluate the pressure on the fauna. The use of Generalized Linear Models realized in the software R 3.4.1 allowed the treatment of the data of the collected species. A total of 2712 game animals, belonging to 09 orders of animals and 34 species, were identified among the samples. The most severed species were small-sized species such as Lepus crawashayi (31.12%), Francolinus bicalcaratus (29.09%), and Thryonomys swinderianus (10.88%). Most game is slaughtered in the fields (53.28%), fallows (29.17%) and on rocky outcrops (3.32%), and some are taken from the protected savannah (1.29%). The samples are non-selective, resulting in damage to wildlife biodiversity. This pressure is also manifested by the presence of endangered species in the IUCN Red List samples, such as the vulnerable Ourebie (Ourebia ourebia) (VU) and Denham's Bustard (Neotis denhami), another critically endangered species (CR). The harvested species are small resilient species that are resistant to hunting pressure for the moment. As the population increases, this hunt will no longer be sustainab...
Illegal hunting of wildlife is one of the major issues in tropical ecosystems, especially when it occurs in highly degraded habitats with forest cover fragmentation. In this study, we assessed the impact of bushmeat hunting in a large forest patch (the Lama Natural Forest; LNF) and 11 nearby forest islands, using Traditional Ecological Knowledge from 240 interviewees across 16 villages. Thirty‐five species belonging to nine orders of mammals, birds and reptiles were mentioned by local communities. Rodentia were significantly more observed in the forest islands, whereas medium‐sized mammals belonging to Carnivora, Primates, Artiodactyla, Pholidota and Hyracoida were found predominantly in LNF. Approximately 57% of the species were reported to be rare in the forest islands, whereas c. 77% were listed as abundant in LNF, confirming the role of LNF as a refuge for forest species targeted by the bushmeat trade. Generalised linear models indicated that species sighting frequencies were positively correlated with perimeters of forest patches. We found hunting pressure to be greater in forest islands in the vicinity of LNF than those further away. Our results suggest that long‐term conservation of wildlife in southern Benin may require a ‘mainland‐islands’ approach including both LNF and its surrounding forest islands.
Protected areas play an important role in the sustainable conservation of biodiversity. In southern Benin Republic, the Lama Forest Reserve is a refuge for wildlife. It also generates significant incomes for the local population. However, anthropogenic activities together with uncontrolled hunting are increasingly threatening the sustainability of these resources. The study aims at investigating the hunting activities characteristics and the morphometric traits of hunted species in the Lama Forest Reserve. Snowball method has been used to constitute the sample of field respondents. Descriptive and inference statistics have been carried out to show results and analyze data. The results show that twenty-three species are mainly hunted, more for trade than for subsistence, with a dominance of mammals. It should be noted that hunting activities don't have the same level among hunted games, species and sexes although this is not generally significant statistically.
The Ptychadenidae Dubois, 1987 are a frog family endemic to Sub-Saharan Africa and Madagascar (Frost 2008). Within the genus Ptychadena Boulenger, 1917 49 species are currently recognized as valid (Frost 2008), most of them breeding in temporary savanna ponds (Rödel 2000; Channing 2001; Channing & Howell 2006). In the Pendjari Biosphere Reserve (PBR) in northern Benin this genus is extraordinary diverse. Here we recorded seven sympatric and partly syntopic Ptychadena species (Nago et al. 2006). The tadpoles of six West African species, P. bibroni (Hallowell, 1845), P. pumilio (Boulenger, 1920), P. oxyrhynchus (Smith, 1849), P. tellinii (Peracca, 1904), P. tournieri (Guibé & Lamotte, 1955) and P. trinodis (Boettger, 1881) have already been described (Lamotte & Zuber-Vogeli 1953; Guibé & Lamotte 1958; Lamotte et al. 1958, 1959; Lamotte & Perret 1961; Perret 1966; Rödel 2000; Rödel & Spieler 2000). Hence, P. schillukorum (Werner, 1908 “1907”) is the only West African savanna Ptychadena with an unknown tadpole. P. schillukorum ranges from Senegal, east to south-western Ethiopia and southern Somalia, south to Malawi, central Mozambique, south-eastern Democratic Republic of Congo and western Angola (Channing 2001; Nago et al. 2006). Recently it was reported from Egypt (Baha el Din 2006). It is hence either a very widespread savanna species or a member of a complex of cryptic species (see Nago et al. 2006 and Frost 2008 for synonyms of P. schillukorum). In West Africa it only occurs in drier savannas. In PBR these frogs breed in shallow savanna ponds, often in syntopy with Phrynobatrachus francisci Boulenger, 1912 and Phrynobatrachus natalensis (Smith, 1849) (Nago et al. 2006). The PBR is located in the Soudanian savanna zone in northern Benin (N 10°30-11°30, E 0°50-2°00). The climate is characterized by a short rainy season from late May or even June/July to early October. The mean annual precipitation is 1000 mm and the mean annual temperature is 27°C. For more details see Nago et al. (2006).
En ce moment où la Série Sciences Naturelles et Agronomie fête 10 années d’existence et que nous terminons la publication du 10ème volume de la série, nous avons choisi d’honorer la mémoire de celui qui en a été le pionnier. Le Professeur Sokpon a été, en effet, l’un des initiateurs des Annales de l’Université de Parakou en 2010. Il a surtout animé la Série Sciences Naturelles et Agronomie de 2010 jusqu’à son décès en février 2015. Au cours de cette période, il a coordonné la publication des 3 premiers volumes avec au total 21 articles d’auteurs de diverses institutions et nationalités. Nous revenons dans les paragraphes ci-dessous sur son parcours et sa contribution inoubliable à la foresterie béninoise et africaine. Il s’agit en somme de 28 années au service des universités, et d’un parcours d’une intensité exceptionnelle.
Cette synthèse bibliographique vise à comprendre l’état des connaissances des pratiques de chasse et leurs effets sur les espèces de faune dans les périphéries des Aires Protégées d’Afrique de l’Ouest. Elle identifie également les lacunes dans les critères de classification des types de chasse et la prise en compte des aspects théoriques dans les diverses analyses. Trois types de chasse dont la chasse de subsistance (27,5% des documents), la chasse commerciale (63,75%) et la chasse sportive (8,75%) ont été identifiés. Si la chasse de subsistance prélève les oiseaux et les rongeurs en majorité, la chasse commerciale capture toutes les espèces rencontrées tandis que la chasse sportive abat les espèces avec les trophées comme les éléphants et les lions. L’impact négatif de la chasse est dénoncé par les auteurs lus. Bien que la prise en compte des aspects spatiaux et environnementaux et les caractéristiques biologiques des espèces prélevées soient importante dans la gestion de la faune, les documents analysés ont occulté ces aspects. Le présent travail suggère des études complètes sur la chasse traditionnelle en y intégrant les aspects spatiaux et environnementaux. This bibliographic review aims to understand the state of knowledge of hunting practices and their effects on species of fauna in the outskirts of West African Protected Areas. It also identifies the gaps in the criteria for classifying the types of hunting and the taking into account of theoretical aspects in the various analyzes. Three types of hunting including subsistence hunting (27.5% of documents), commercial hunting (63.75%) and sport hunting (8.75%) were identified. While subsistence hunting takes the majority of birds and rodents, commercial hunting captures all the species encountered while sport hunting cuts down species with trophies such as elephants and lions. The negative impact of hunting is denounced by the authors read. Although the consideration of spatial and environmental aspects and the biological characteristics of the species collected are important in wildlife management, the documents analyzed have overlooked these aspects. The present work suggests comprehensive studies on traditional hunting by integrating spatial and environmental aspects.
