我们使用2005年和2018年的可比种群数据来评估导致狮子豹狮群数量下降的威胁，并审查通过问题树和根本原因分析构建的威胁信息。我们定义了11种威胁，并对它们的严重性和流行率进行了排名。出现了两种威胁，影响到狮子的数量和其中的数量：掠夺牲畜导致报复性捕杀狮子，偷猎丛林肉类导致猎物枯竭。我们的数据不能确定是否有任何特定的威胁导致的下降速度快于其他威胁。在20起地方驱逐案中，大多数与武装冲突有关，是直接威胁的驱动力。我们讨论了最近威胁的普遍性和严重性及其驱动因素，以确定更有效地保护狮子、其他食肉动物及其猎物的优先事项。
We use comparable 2005 and 2018 population data to assess threats driving the decline of lion Panthera leo populations, and review information on threats structured by problem tree and root cause analysis. We define 11 threats and rank their severity and prevalence. Two threats emerged as affecting both the number of lion populations and numbers within them: livestock depredation leading to retaliatory killing of lions, and bushmeat poaching leading to prey depletion. Our data do not allow determination of whether any specific threat drives declines faster than others. Of 20 local extirpations, most were associated with armed conflicts as a driver of proximate threats. We discuss the prevalence and severity of proximate threats and their drivers, to identify priorities for more effective conservation of lions, other carnivores and their prey.
