Group 1: Ecological Significance - The Chinese merganser, known as the "panda of birds," has been spotted in the Yihe River for five consecutive years, indicating a stable wintering habitat [3]. - The species is highly selective regarding its habitat, requiring high water quality, food resources, and minimal ecological disturbance, making its presence a strong indicator of ecological health [3][4]. Group 2: Conservation Efforts - Local authorities have established a comprehensive protection network involving monitoring, patrolling, and public awareness campaigns to safeguard the species [4]. - The population of Chinese mergansers has increased from two to three individuals in 2021 to a stable count of 18, reflecting the success of conservation initiatives [4]. - Collaborative efforts among forestry departments, police, and market regulation agencies have intensified actions against illegal hunting and wildlife trade, creating a secure environment for the birds [4]. Group 3: Biodiversity and Community Involvement - The Yihe River has become a winter haven not only for the Chinese merganser but also for various other rare waterfowl, contributing to a vibrant "winter bird market" [4]. - Local volunteer groups have emerged to clean riverbanks and promote conservation awareness, fostering a community-centric approach to ecological protection [4][5].
