Hunting, Law Enforcement, and African Primate Conservation

Primates are regularly hunted for bushmeat in tropical forests, and systematic ecological monitoring can help determine the effect hunting has on these and other hunted species. Monitoring can also be used to inform law enforcement and managers of where hunting is concentrated. We evaluated the effe...

Description
Summary:Primates are regularly hunted for bushmeat in tropical forests, and systematic ecological monitoring can help determine the effect hunting has on these and other hunted species. Monitoring can also be used to inform law enforcement and managers of where hunting is concentrated. We evaluated the effects of law enforcement informed by monitoring data on density and spatial distribution of 8 monkey species in Taï National Park, Côte d'Ivoire. We conducted intensive surveys of monkeys and looked for signs of human activity throughout the park. We also gathered information on the activities of law-enforcement personnel related to hunting and evaluated the relative effects of hunting, forest cover and proximity to rivers, and conservation effort on primate distribution and density. The effects of hunting on monkeys varied among species. Red colobus monkeys (Procolobus badius) were most affected and Campbell's monkeys (Cercopithecus campbelli) were least affected by hunting. Density of monkeys irrespective of species was up to 100 times higher near a research station and tourism site in the southwestern section of the park, where there is little hunting, than in the southeastern part of the park. The results of our monitoring guided law-enforcement patrols toward zones with the most hunting activity. Such systematic coordination of ecological monitoring and law enforcement may be applicable at other sites. Los primates son cazados regularmente en bosques tropicales, y el monitoreo ecológico sistemático puede ayudar a determinar el efecto de la caza sobre estas y otras especies. El monitoreo también puede ser utilizado en la aplicación de la ley y por gestores de sitios donde se concentra la cacería. Evaluamos los efectos de la aplicación de la ley con base en datos de monitoreo de la densidad y distribución espacial de 8 especies de mono en el Parque Nacional Taï, Costa de Marfil. Realizamos muestreos intensivos de monos y buscamos señales de actividad humana en el parque. También reunimos información sobre las actividades de agentes del orden público relacionada con la caza y evaluamos los efectos relativos de la caza, cobertura forestal y cercanía a ríos, y los de los esfuerzos de conservación sobre la distribución y densidad de primates. Los efectos de la caza sobre monos varió entre especies. El mono Colobus rojo (Procolobus badius) fue la especie más afectada y el mono Campbell (Cercopithecus campbelli) fue la especie menos afectada por la caza. La densidad
