Vulture populations are in severe decline across Africa and prioritization of geographic areas for their conservation is urgently needed. To do so, we compiled three independent datasets on vulture occurrence from road-surveys, GPS-tracking, and citizen science (eBird), and used maximum entropy to build ensemble species distribution models (SDMs). We then identified spatial vulture conservation priorities in Ethiopia, a stronghold for vultures in Africa, while accounting for uncertainty in our predictions. We were able to build robust distribution models for five vulture species across the entirety of Ethiopia, including three Critically Endangered, one Endangered, and one Near Threatened species. We show that priorities occur in the highlands of Ethiopia, which provide particularly important habitat for Bearded Gypaetus barbatus, Hooded Necrosyrtes monachus, Rüppell’s Gyps rüppelli and White-backed Gyps africanus Vultures, as well as the lowlands of north-eastern Ethiopia, which are particularly valuable for the Egyptian Vulture Neophron percnopterus. One-third of the core distribution of the Egyptian Vulture was protected, followed by the White-backed Vulture at one-sixth, and all other species at one-tenth. Overall, only about one-fifth of vulture priority areas were protected. Given that there is limited protection of priority areas and that vultures range widely, we argue that measures of broad spatial and legislative scope will be necessary to address drivers of vulture declines, including poisoning, energy infrastructure, and climate change, while considering the local social context and aiding sustainable development.

非洲之角的秃鹫保护重点地区大部分不在保护区网络范围内

整个非洲的秃鹰数量正在严重下降,迫切需要优先考虑地理区域的保护。为此,我们从道路调查、GPS 跟踪和公民科学 (eBird) 中编译了三个关于秃鹰发生的独立数据集,并使用最大熵来构建整体物种分布模型 (SDM)。然后,我们确定了埃塞俄比亚的空间秃鹰保护优先事项,这是非洲秃鹰的据点,同时考虑了我们预测中的不确定性。我们能够为整个埃塞俄比亚的五种秃鹰建立强大的分布模型,包括三种极度濒危、一种濒危和一种近危物种。我们表明优先事项发生在埃塞俄比亚的高地,这为胡须提供了特别重要的栖息地Gypaetus barbatus、Hooded Necrosyrtes monachus、Rüppell's Gyps rüppelli和 White-backed Gyps Africanus Vultures,以及埃塞俄比亚东北部的低地,对埃及秃鹫Neophron percnopterus特别有价值. 埃及秃鹰核心分布的三分之一受到保护,其次是白背秃鹰的六分之一,所有其他物种的十分之一。总体而言,只有大约五分之一的秃鹫优先区域受到保护。鉴于对优先区域的保护有限且秃鹰分布广泛,我们认为,在考虑当地社会环境的同时,需要采取广泛的空间和立法范围措施来解决秃鹰数量下降的驱动因素,包括中毒、能源基础设施和气候变化。环境和帮助可持续发展。
