Core Points - The collaboration between Beijing Forestry University, Beijing Zoo, and Hengshui Lake National Nature Reserve has achieved significant results in the artificial breeding and rewilding of the critically endangered Baikal teal [1][2] - Hengshui Lake is a crucial breeding and wintering site for the Baikal teal, with a recorded population of 308 individuals in 2017, highlighting its importance in conservation efforts [1] - The project began in 2022, and by 2024, nine adult Baikal teals were successfully transported to establish a breeding base, leading to the natural breeding of 13 ducklings in the first generation and further success in the second generation [1] Group 1 - The project has established a stable natural breeding population of Baikal teals after two complete breeding seasons [1] - Valuable data on the breeding habits and habitat requirements of Baikal teals has been accumulated, providing a systematic "Chinese solution" for global conservation efforts [2] - Future efforts will focus on habitat management optimization and promoting harmonious coexistence between humans and wildlife, contributing to global wetland biodiversity protection [2]

Core Viewpoint - The collaboration between Beijing Forestry University, Beijing Zoo, and Hengshui Lake National Nature Reserve has achieved significant progress in the artificial breeding and rewilding of the critically endangered Baikal teal, establishing a stable natural breeding population [1][2]. Group 1: Project Achievements - A stable natural breeding population of Baikal teal has been successfully established after two complete breeding seasons [1]. - In 2022, the project initiated with the transfer of 9 adult Baikal teals (5 females and 4 males) from Beijing Zoo to Hengshui Lake, leading to the first generation of 13 ducklings in the same year [1]. - The second generation of ducklings was successfully bred in June of the following year [1]. Group 2: Importance of Hengshui Lake - Hengshui Lake is a crucial breeding and wintering site for the globally critically endangered Baikal teal, with 308 individuals monitored in 2017, highlighting its significance for conservation efforts [1]. - The lake has become an important research area for improving the conservation status of the species [1]. Group 3: Future Directions - The research team has gathered valuable data on the breeding habits and habitat requirements of Baikal teal, which will contribute to a systematic "Chinese solution" for global conservation efforts [2]. - Future efforts will focus on optimizing habitat management and promoting harmonious coexistence between humans and wildlife, providing replicable and scalable practices for wetland biodiversity conservation [2].
