In recent years, thanks to intensified ecological conservation efforts in Northeast China, the wild Amur tiger population has steadily rebounded. In protected areas across Jilin and Heilongjiang provinces, infrared-triggered camera traps have repeatedly captured rare footage of Amur tiger families—showing adult tigers leading cubs on patrols or foraging. These cameras are typically installed along forest trails or near water sources where wildlife frequently passes. Equipped with motion and heat sensors, they automatically take photos or videos when triggered. Researchers analyze this visual data to identify individual tigers, assess their health and territorial ranges, and evaluate reproductive success and habitat quality. Notably, multiple cameras at different locations have recorded the same tiger family over time, indicating the formation of stable social units and gradual expansion of their territory. These findings not only validate the effectiveness of national park initiatives and ecological corridor restoration but also offer valuable insights for global conservation efforts targeting endangered big cats.
近年来，随着中国东北地区生态保护力度的不断加强，野生东北虎种群数量稳步回升。在吉林、黑龙江等地的自然保护区中，安装的红外触发预警相机多次成功捕捉到东北虎家庭活动的画面，包括成年虎带领幼崽巡山、觅食等珍贵影像。这些相机通常布设在野生动物频繁出没的林区小径或水源附近，一旦感应到体温和移动，便会自动拍摄照片或视频。科研人员通过分析这些影像，不仅能识别个体老虎的身份、健康状况和活动范围，还能评估其繁殖成功率与栖息地质量。尤其令人振奋的是，多台相机在不同地点连续记录到同一虎群的踪迹，说明东北虎正在形成稳定的家族结构，并逐步扩展其活动区域。这不仅印证了国家公园建设和生态廊道修复的成效，也为全球濒危大型猫科动物的保护提供了宝贵经验。
