We studied the impact of hunting on monkey species in the Taï National Park and adjacent forests in Côte d'Ivoire. The average wild meat consumption per capita per year was assessed from market surveys and interviews. We determined that the amount of primate wild meat being extracted in the Taï National Park and surrounding forests was 249 t in 1999. Hunting pressure was the highest on the larger primate species such as red colobus, Procolobus badius, black and white colobus, Colobus polykomos, and the sooty mangabey, Cercocebus torquatus atys. Estimates of population densities were based on line transect surveys. The maximum annual production of each species was calculated using the Robinson and Redford model (1991) and assuming unhunted conditions. Comparing current harvest levels with the maximum sustainable yield suggests that harvest of red colobus monkeys (Procolobus badius) is sustainable, whereas current off-take of the black and white colobus (Colobus polykomos), the sooty mangabey (Cercocebus atys), diana monkeys (Cercopithecus diana), and Campbell's monkeys (Cercopithecus campbelli) exceeds sustainability by up to three times. RÉSUMÉNous avonsétudié l'impact de la chasse sur les espèces de singes dans le Parc National de Taï et ses principales forêts périphériques en Côte d'Ivoire. La consommation moyenne de viande de brousse par capita et par an aété estiméeà partir d'études de marchés et d'interviews. Nous avons estimé la quantité de viande de gibier d'origine simienne extraite du Parc National de Taï en 1999à 249 t. La pression de la chasseétait plus forte sur les espèces de singes de plus grande taille telles que le colobe bai, Procolobus badius, le colobe noir et blanc, Colobus polykomos, et le cercocèbe enfumé, Cercocebus torquatus atys. Les estimations de densité de populations ontété faites par la méthode des transects. La production annuelle maximale de chaque espèce aété calculée en utilisant le modèle de Robinson et Redford (1991) en supposant des conditions sans chasse. La comparaison des prélèvements avec la production maximale soutenable suggère que le prélèvement en cours des colobes bais (Procolobus badius) est soutenable alors que celui de colobes noirs et blancs (Colobus polykomos), des cercocèbes enfumés (Cercocebus torqatus atys), des cercopithèques dianes (Cercopithecus diana) et des mones de Campbell (Cercopithecus campbelli) excède le seuil de durabilité de jusqu'à trois fois.
Threats to biodiversity are well documented. However, to effectively conserve species and their habitats, we need to know which conservation interventions do (or do not) work. Evidence-based conservation evaluates interventions within a scientific framework. The Conservation Evidence project has summarized thousands of studies testing conservation interventions and compiled these as synopses for various habitats and taxa. In the present article, we analyzed the interventions assessed in the primate synopsis and compared these with other taxa. We found that despite intensive efforts to study primates and the extensive threats they face, less than 1% of primate studies evaluated conservation effectiveness. The studies often lacked quantitative data, failed to undertake postimplementation monitoring of populations or individuals, or implemented several interventions at once. Furthermore, the studies were biased toward specific taxa, geographic regions, and interventions. We describe barriers for testing primate conservation interventions and propose actions to improve the conservation evidence base to protect this endangered and globally important taxon.
As a result of forest modification, primates are increasingly having to rely on fragments; so too are the human populations that have historically relied on continuous forest for critical resources. The role of primates in seed dispersal is increasingly understood to have significant unique effects on plant demography and forest regeneration. Our aim in this paper is to explore the potential for monkey seed dispersers to maintain the utility of forest fragments for humans through seed dispersal in the Taï region, western Côte-d'Ivoire. We established a list of fruit species whose seeds are dispersed by seven of eight monkey species occurring in the Taï National Park by using primary data and published accounts of their fruit diet, and determined the abundance of human-used and monkey-dispersed tree species in forest fragments in the broader Taï region. The monkeys of the Taï National Park consumed 75 tree species. Of this total set of 75 species, 52 (69%) were dispersed almost exclusively by monkeys and were found in neighboring forest fragments. Of the 52 fruiting forest tree species that are dispersed by Taï monkeys, 25 (48%) have some utility to local inhabitants suggesting that maintaining populations of primates is important not only for forest regeneration, but also for human populations that rely on forest resources. The conservation of primate species is a critically important goal in itself, but by working to ensure their protection in forest fragments, we certainly protect indirectly the seed dispersal of important human resources in these fragments as well.Key Words: Conservation, forest fragments,forest regeneration, Taï National Park, primate seed dispersal, useful plants Resume Suite à la dégradation des forêts, les primates se retrouvent à dépendre de plus en plus de fragments de forêts. Il en est de même des populations humaines qui par le passé trouvaient leur moyens de subsistance dans des forêts continues. Il est de plus en plus reconnu que la dispersion des graines par les primates à un effet significatif unique sur la démographie et la régénération de la forêt. Le but de cette étude était d'explorer le potentiel des singes à queue pour maintenir l'utilité des fragments forestiers pour les humains à travers la dispersion des graines dans la région de Taï à l'ouest de la Côte-d'Ivoire. Pour cela, nous avons d'abord établi une liste des espèces des fruits dont les graines sont dispersées par sept des huit espèces de singes à queue dans le Parc National de Taï en utilisant des données d'observations personnelles ainsi que des données publiées par d'autres auteurs. Nous avons ensuite déterminé l'abondance, dans les fragments forestiers de la région de Taï, des espèces d'arbres dont les graines sont dispersées par les singes à queue en mettant l'accent sur les plantes utilisées par les humains. Les singes à queue frugivores du Parc National de Taï ont consommé les fruits de 75 espèces d'arbres dont 52 (69%) produisaient des graines dispersées de façon quasi exclusive par les singes et se r...
Advancing technology represents an unprecedented opportunity to enhance our capacity to conserve the Earth's biodiversity. However, this great potential is failing to materialize and rarely endures. We contend that unleashing the power of technology for conservation requires an internationally coordinated strategy that connects the conservation community and policy-makers with technologists. We argue an international conservation technology entity could (1) provide vision and leadership, (2) coordinate and deliver key services necessary to ensure translation from innovation to effective deployment and use of technology for on-the-ground conservation across the planet, and (3) help integrate innovation into biodiversity conservation policy from local to global scales, providing tools to monitor outcomes of conservation action and progress towards national and international biodiversity targets. This proposed entity could take the shape of an international alliance of conservation institutions or a formal intergovernmental institution. Active and targeted uptake of emerging technology can help society achieve biodiversity conservation goals.
