A wild Siberian tiger, known as "Wanda Mountain No.1", had once again been captured by their wildlife infrared cameras in a protected area in northern China.

Compared to previous sightings, the tiger appeared to be more robust and glossy.

The Siberian tiger, a flagship species for global biodiversity conservation, had first been successfully rescued in China on April 23, 2021. Named "Wanda Mountain No.1" after being spotted in the southwestern hilly region of Heilongjiang's Wanda Mountains, it was returned to the wild on May 18 of the same year.

This time, staff during a routine patrol in the core area of the northeast China National Nature Reserve and Muling Park of the Northeast Tiger and Leopard National Park, once again spotted "Wanda Mountain No.1". In the video, a sturdy Siberian tiger strides confidently, casually passing in front of the camera.

According to Dr Zhao Yue from the National Forestry and Grassland Administration's Felidae Research Center at Northeast Forestry University, the footage of the tiger was taken in April 2023. After comparison, it was confirmed to be "Wanda Mountain No.1", indicating its successful return to its original habitat.

Additionally, staff members also spotted the silhouettes of two leopards - one large, one small - in other infrared cameras. These leopards, as well as other wildlife species such as brown bears, roe deer, sika deer, and other creatures, were seen thriving in the Muling Forest region, with their populations continually growing.

7月12日，龙江森工集团穆棱林业局有限公司发布消息，该公司保护区在野外红外线相机中，再次发现野生东北虎“完达山1号”清晰的活动影像。较之从前，它皮毛光亮，体格壮硕了不少。
东北虎是全球生物多样性保护的旗舰物种，中国于2021年4月23日首次成功救护一只野生东北虎，并因其现身黑龙江完达山西南丘陵地带而命名为“完达山1号”。同年5月18日，“放虎归山”。
此次，工作人员在例行巡护中，于东北红豆杉中国国家级自然保护区核心区、东北虎豹中国国家公园穆棱园区内，再次发现了“完达山1号”的身影。视频中，一只体型健硕的东北虎迈着矫健步伐，悠然地从镜头前走过。
据东北林业大学中国国家林草局猫科动物研究中心的赵越博士介绍，视频显示这只东北虎被拍摄的时间为2023年4月。经过比对，系此前在穆棱林区放归山林的“完达山1号”，“他”再次“溜达回家”了。
此外，工作人员还分别在其他红外相机中，发现一大一小两只东北豹的身影，它们在林间恣意穿梭，巡视领地、觅寻食物，还发现了棕熊、狍子、梅花鹿、马鹿等野生动物在穆棱林区栖息繁衍，且种群数量不断增加。
据保护区工作人员介绍，东北虎、东北豹愿意以穆棱林区为家，说明这里食物链完整，生物多样性丰富，生态环境得到了有效恢复。如今，穆棱林区逐渐成为野生动物自由繁衍、生长生活的美好家园。
