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]

5月22日是国际生物多样性日。记者从国家林业和草原局获悉，通过实施以国家公园为主体的自然保护 地体系建设及野生动植物保护工程，我国珍稀濒危野生动植物种群数量稳步增长，栖息繁衍环境稳步改 善，生物多样性保护成效显著。 据介绍，国家林草局将加快构建以国家公园为主体的自然保护地体系，积极推动出台国家公园法，按 照"成熟一个、设立一个"的原则，严格把关，稳慎有序设立新的国家公园。同时进一步完善由植物园、 种质资源库、野生动物救护繁育基地等构成的迁地保护体系；实施生物多样性保护重大工程，推动濒危 物种野外种群复壮，持续开展打击野生动植物非法贸易行动，全面加强生物多样性保护。 (责任编辑：谭梦桐) 目前，全国200多种珍稀濒危野生动物进入恢复性增长阶段，100余种濒危野生植物得到抢救性保护。 2024年全国水鸟同步监测最新结果显示，我国越冬水鸟总数量达505.9万只，为迄今全国范围内监测数 量的最高纪录。 据介绍，近年来我国扎实推进野生动植物保护，加快构建以国家公园为主体的自然保护地体系，发布陆 生野生动物重要栖息地名录，组织开展野生动植物栖息地(原生境)保护修复和监测体系建设，为野生动 植物生存繁衍营造良好条件。同时积 ...
