This study aims to fill the knowledge gap and provide evidence of resident African wild dog (Lycaon pictus) populations in the northeast of Luengue-Luiana National Park (LLNP) in Angola. Camera traps and direct observations were used to collect data between 2021 and 2023. The results confirm the presence of multiple distinct groups of resident wild dogs within LLNP, with 26–28 individuals identified in each survey year; including captures of females, individuals at different age classes and the same individuals across multiple surveys. The findings support the revision of the IUCN/SSC distribution range of wild dogs in southeastern Angola. It also highlights the lower wild dog numbers in the southeast of LLNP, potentially limiting dispersal to neighbouring countries.

安哥拉卢恩格-卢亚纳国家公园常驻非洲野狗（Lycaon pictus）种群的证据

本研究旨在填补安哥拉卢恩格-卢亚纳国家公园 (LLNP) 东北部常驻非洲野狗 ( Lycaon pictus ) 种群的知识空白并提供证据。使用相机陷阱和直接观察来收集 2021 年至 2023 年间的数据。结果证实，LLNP 内存在多个不同的常驻野狗群体，每个调查年识别出 26-28 只野狗；包括女性、不同年龄段的个人以及多次调查中的同一个人的数据。这些发现支持对安哥拉东南部野狗的 IUCN/SSC 分布范围进行修订。它还强调了 LLNP 东南部野狗数量较少，这可能限制了野狗向邻国的扩散。
