Anthropogenic pressures drive landscape transformation and climate change, which threaten habitat suitability and often perpetuates biodiversity loss. Wide-ranging behaviour in large carnivores typically conflicts with human activities driving population declines. Cheetah are particularly vulnerable, with the smallest remaining global population occupying only 9% of their historical range. This study aimed to define and delineate suitable cheetah habitat under current and future climate scenarios across southern Africa. Using multi-source presence records since 1980, we performed species distribution models for both free-roaming and managed reserve populations. Here we compare the relative loss or gain of projected suitable cheetah habitat to the established range and protected area network.

人为压力（Anthropogenic pressures）驱动景观转型与气候变化，二者既威胁栖息地适宜性，又会加剧生物多样性丧失。大型食肉动物的广域活动通常会与导致种群衰退的人类活动产生冲突。猎豹（Cheetah）尤为脆弱，现存全球种群规模极小，其栖息范围仅占历史分布区的9%。本研究旨在明确并划定南非当前及未来气候情景下适宜猎豹栖息的区域。研究团队利用1980年以来的多源物种出现记录，针对自由扩散种群与保护区管理种群分别构建了物种分布模型（Species Distribution Models）。本研究对比了预测得到的适宜猎豹栖息地的相对增减幅度与既定分布范围及保护区网络的差异。
