Abstract. Since the accident at the Chornobyl nuclear power plant in 1986 there have been few studies published on medium/large mammals inhabiting the area from which the human population was removed (now referred to as the Chornobyl Exclusion Zone). The dataset presented in this paper describes a motion activated camera trap study (n=21 cameras) conducted from September 2016–September 2017 in the Red Forest located within the Chornobyl Exclusion Zone. The Red Forest, which is likely the most anthropogenically contaminated radioactive terrestrial ecosystem on earth, suffered a severe wildfire in July 2016. The motion activated trap cameras were therefore in place as the Red Forest recovered from the wildfire. A total of 45859 images were captured and of these 19391 contained identifiable species or organism types (e.g. insects). A total of 14 mammal species were positively identified together with 23 species of birds (though birds were not a focus of the study). Weighted absorbed radiation dose rate rates were estimated for mammals across the different camera trap locations; the number of species observed did not vary with estimated dose rate. We also observed no relationship between estimated weighted absorbed radiation dose rates and the number of triggering events for the four main species observed during the study (Brown hare, Eurasian elk, Red deer, Roe deer). The data presented will be of value to those studying wildlife within the CEZ both from the perspectives of the potential effects of radiation on wildlife and also rewilding in this large, abandoned area. They may also have value in any future studies investigating the impacts of the recent Russian military action in the CEZ.

切尔诺贝利禁区红森林中的哺乳动物：运动激活相机陷阱研究

摘要。自 1986 年切尔诺贝利核电站事故以来，很少有关于居住在人口迁移区域（现称为切尔诺贝利禁区）的中型/大型哺乳动物的研究发表。本文介绍的数据集描述了 2016 年 9 月至 2017 年 9 月在切尔诺贝利禁区内的红森林中进行的运动激活相机陷阱研究（n = 21 个相机）。红森林可能是地球上受人为污染最严重的放射性陆地生态系统，它在 2016 年 7 月遭受了严重的野火。因此，随着红森林从野火中恢复，运动激活的陷阱摄像机就位。总共捕获了 45859 张图像，其中 19391 张包含可识别的物种或生物类型（例如昆虫）。总共确定了 14 种哺乳动物和 23 种鸟类（尽管鸟类不是研究的重点）。估计了哺乳动物在不同相机陷阱位置的加权吸收辐射剂量率；观察到的物种数量不随估计的剂量率变化。我们还观察到估计的加权吸收辐射剂量率与研究期间观察到的四种主要物种（棕兔、欧亚麋鹿、红鹿、獐鹿）的触发事件数量之间没有关系。从辐射对野生动物的潜在影响的角度来看，所提供的数据对于那些在 CEZ 内研究野生动物的人来说都是有价值的，而且还从这个大的废弃地区重新野生化的角度来看。它们也可能对未来调查俄罗斯在 CEZ 的军事行动的影响的任何研究有价值。数据和支持文档可根据知识共享署名 (CC BY) 许可的条款和条件从环境信息数据中心 (EIDC) 免费获得：https://doi.org/10.5285/bf82cec2-5f8a-407c-bf74 -f8689ca35e83（Barnett 等人，2022a）。
