Core Viewpoint - The article highlights the successful reintroduction of the critically endangered species, the large-flowered stone butterfly, into its natural habitat in Yunnan, China, showcasing China's commitment to biodiversity conservation and the innovative approaches taken in species protection efforts [1][2][10]. Group 1: Species Conservation Efforts - The large-flowered stone butterfly was rediscovered by Chinese researchers in 2021 after being considered "lost" for over a century, leading to breakthrough cultivation in laboratories [2][3]. - The reintroduction of the species involved careful planting of seedlings into their native soil, demonstrating a significant step in the conservation of endangered species [1][12]. - The Southwest China Wild Biological Germplasm Resource Bank has become a critical support system for the conservation efforts, housing a vast collection of rare and endangered plant seeds [2][3]. Group 2: Germplasm Resource Bank - The Southwest China Wild Biological Germplasm Resource Bank is the only national-level facility of its kind in the country, preserving 27,000 species and 330,000 samples of wild biological germplasm, making it the largest in Asia [2][3]. - The resource bank has achieved international leading levels in the long-term preservation of various wild plant seeds, plant tissues, DNA, fungi, and microorganisms [3]. Group 3: Technological and Community Engagement - The conservation efforts are supported by advanced technologies, including genetic diversity analysis and innovative breeding techniques, which have led to the successful cultivation of hundreds of seedlings of the large-flowered stone butterfly [2][10]. - Community involvement has shifted from hunting to conservation practices, contributing to the overall success of biodiversity initiatives in the region [8].

Group 1 - The Beijing Science and Technology Week has showcased 12 research achievements from municipal parks, which positively impact urban park ecology, biodiversity, and resident well-being [1] - The artificial population of the critically endangered Baikal teal has exceeded 100 individuals, marking a significant milestone in conservation efforts since the initiation of a systematic protection project in 2019 [2] - Research on the invasive Juniper scale insect has led to the identification of its host plants and life cycle, resulting in comprehensive control measures to mitigate its impact [3] Group 2 - Technological advancements have significantly improved the restoration of cherry blossoms in Yuyuantan Park, with a custom formula increasing new shoot growth by 32% and root vitality by 50% [4] - The National Botanic Garden has established a resource bank for crabapple species, collecting over 200 classification units and 800 specimens, contributing to species conservation [4] - The research on the "Xiangshan Route Map" has provided valuable insights into Qing Dynasty history and geography, aiding in the preservation of historical sites [5][6] Group 3 - The Beijing Municipal Park Management Center emphasizes the role of scientific research in enhancing urban park management, contributing to ecological system construction and enriching public green space experiences [6]

Core Viewpoint - The article discusses the critically endangered species, the Yangtze Giant Softshell Turtle (Rafetus swinhoei), highlighting that only one individual remains in China, making it one of the rarest animals in the world [2][4][7]. Group 1: Species Information - The Yangtze Giant Softshell Turtle is the largest freshwater turtle, with a carapace length of up to 1.5 meters and a weight of 115 kilograms [7]. - Historically, this species was widely distributed in the Yangtze River basin and other regions, but its population has drastically declined, with only two known individuals remaining globally, both of which are male [7][8]. - The last known individual in China, named "Su Su," has been living in the Suzhou Upfangshan Forest Animal World since the 1950s [2][10]. Group 2: Conservation Efforts - Previous attempts to breed "Su Su" with a female turtle named "Xiang Xiang" from Changsha Zoo were unsuccessful, as all offspring died shortly after hatching [10]. - Experts suggest that conservation efforts should include both in-situ and ex-situ strategies, such as establishing protected areas and artificial breeding centers [12]. - Research on the breeding biology of the turtle has led to significant advancements, including the establishment of a breeding base for the species, which could provide insights for the conservation of other endangered species [12].
