South African protected areas account for 8% of the total landmass according to World Bank indicators. Effective conservation of biodiversity in protected areas requires the development of specific reserve management objectives addressing species and disease management. The primary objective of the current study was to identify predictors of carnivore detection in an effort to inform carnivore species management plans on Andover and Manyeleti nature reserves in South Africa. A limited number of camera traps were placed randomly using a grid system. Species detection data were analysed using mixed-effects logistic regression and Spearman's correlation coefficients. Deterministic inverse distance weighted distribution maps were used to describe the spatial distribution of carnivore species. Camera traps identified similar species as traditional call-up surveys during the study and would be useful as an adjunct census method. Carnivore detection was associated with several variables, including the presence of specific prey species. The measured intra-and interspecies interactions suggested the risk of disease transmission among species, and vaccination for prevalent diseases should be considered to manage this risk.
根据世界银行的指标,南非的保护区占其陆地总面积的8%。要在保护区有效地保护生物多样性,就需要制定针对物种和疾病管理的特定保护区管理目标。本研究的主要目的是确定食肉动物被发现的预测因素,以便为南非安多弗和曼耶莱蒂自然保护区的食肉动物物种管理计划提供信息。使用网格系统随机放置了数量有限的相机陷阱。物种检测数据采用混合效应逻辑回归和斯皮尔曼相关系数进行分析。确定性反距离加权分布图用于描述食肉动物物种的空间分布。在研究期间,相机陷阱识别出的物种与传统的召集调查相似,可作为辅助普查方法。食肉动物的发现与几个变量有关,包括特定猎物物种的存在。所测量的种内和种间相互作用表明了物种间疾病传播的风险,应考虑对流行疾病进行疫苗接种以管理这种风险。
