Core Viewpoint - The article highlights the critical situation of the endangered red mangrove species, Rhizophora stylosa, in Hainan, China, emphasizing conservation efforts and the importance of habitat restoration for its survival [3][6][11]. Group 1: Current Status of Red Mangrove - The red mangrove, referred to as the "panda of mangroves," is critically endangered, with only 13 original specimens remaining in China as of the latest survey, down from 14 in 2016 [3][6]. - The original population in Lingshui has decreased to 4 specimens, indicating a severe decline in its natural habitat [3][6]. Group 2: Factors Affecting Survival - Human activities, climate change, and habitat degradation have significantly impacted the red mangrove's survival, with an 80% seed sterility rate reported, hindering natural regeneration [6][10]. - The remaining specimens are showing signs of aging and decline, with some trees exhibiting hollow trunks and parasitic growths that threaten their health [6][10]. Group 3: Conservation Efforts - The protection level of the red mangrove was upgraded from national second-class to first-class in August 2021, reflecting its critical status [7]. - Conservation actions include habitat restoration, removal of over 1,600 acres of aquaculture ponds, and the establishment of protective measures for ancient trees [9][11]. - Research teams have achieved significant advancements in seed germination rates, increasing from 0.3% to 17%, and have successfully cultivated over 2,000 red mangrove seedlings in the wild [11][12]. Group 4: Future Plans - Ongoing efforts aim to explore natural growth patterns without human intervention and further improve seed germination rates to ensure the species can thrive independently [12].

Group 1 - The core viewpoint is that over 100 endangered wild plant species in China are under rescue protection, with artificial breeding being a key method for their conservation [1][2] - Common endangered plants like Taxus chinensis, Ginkgo biloba, and Metasequoia glyptostroboides are often found in urban areas, but they are artificially bred rather than naturally reproduced due to their limited wild populations [1] - Successful artificial breeding has been achieved for several endangered plants, allowing for the establishment of larger artificial populations that contribute to ecological and landscape functions [1] Group 2 - Despite the establishment of large artificial populations, endangered plants like Ginkgo and Metasequoia still face extinction risks due to limited wild distribution and genetic diversity [2] - The government has included endangered plants in key protection lists to safeguard both the plants and their ecosystems, recognizing that artificial breeding alone is insufficient for their protection [2] - Various methods are employed for the conservation of endangered plants, including seed collection for seed banks, ex-situ conservation of wild individuals, and the establishment of protected areas [2]
