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]
