二龙涛河 百鸟翱翔（我家门前有条河）

Core Viewpoint - The restoration of the Erlongtao River has led to a significant revival of the local ecosystem, particularly benefiting migratory birds like the white crane, and fostering community involvement in environmental protection efforts [1][2]. Group 1: Environmental Restoration - The Erlongtao River, which had dried up due to drought and dam construction over 20 years ago, began to recover in 2014 with the implementation of river-lake connectivity projects [1]. - The influx of clean water from the Nenjiang and Taoer Rivers has rejuvenated the wetlands, allowing vegetation to regrow and attracting migratory birds back to the area [1]. Group 2: Community Involvement - A volunteer team, the Wildlife Protection Association of Jilin Baicheng, was established to monitor and protect the local bird population, conducting various activities throughout the year [2]. - The efforts of volunteers have resulted in the rescue of injured protected bird species and the documentation of hundreds of thousands of bird images, indicating a growing commitment to environmental stewardship [2]. Group 3: Ecological Impact - The presence of migratory birds serves as an indicator of the river's ecological health, with increasing numbers of white cranes and the return of previously absent species like the tufted duck [2]. - The revitalization of the river has not only improved the local ecosystem but has also enhanced the quality of life for residents, contributing to economic opportunities such as eco-tourism and agriculture [4].
