High human‐caused mortality due to wildlife‐vehicle‐collisions and illegal killing leads to frequent cases of orphaned Eurasian lynx juveniles. Under natural conditions, this would result in starvation of the young. To avoid this, wildlife managers conventionally rear animals in captivity and release them later. However, this measure is an undesirable outcome for species conservation, managers, and animals alike. Increased awareness of Eurasian lynx orphaned by human‐caused mortality means managers must often intervene in endangered populations. In this study, we report for the first time a successful case of in situ feeding designed to avoid captivity of two orphaned Eurasian lynx. We exposed 13 roe deer and 7 red deer carcasses in the field to successfully support two orphans to the age of independence and confirm dispersal from the natal range. We present this management approach as a feasible and complimentary tool that can be considered in small or isolated large carnivore populations where every individual counts toward population viability.

就地喂养作为保护孤儿欧亚山猫（lynx lynx）的新管理工具

由于野生动物与车辆碰撞和非法捕杀造成的人为死亡率很高，导致欧亚山猫幼崽成为孤儿的情况频繁发生。在自然条件下，这会导致幼崽挨饿。为了避免这种情况，野生动物管理者通常圈养动物，然后再释放它们。然而，这种措施对于物种保护、管理者和动物来说都是不受欢迎的结果。人们对因人为死亡而成为孤儿的欧亚山猫的认识不断提高，这意味着管理人员必须经常对濒临灭绝的种群进行干预。在这项研究中，我们首次报告了一个成功的就地喂养案例，旨在避免圈养两只孤儿欧亚山猫。我们在野外暴露了 13 头狍子和 7 头马鹿尸体，成功地将两名孤儿抚养到独立年龄，并确认了它们从出生地的扩散。我们将这种管理方法作为一种可行且补充的工具，可以在小型或孤立的大型食肉动物种群中考虑，其中每个个体都对种群生存能力产生影响。
