Results show that a total of 13 invasive alien species were discovered in Yuhang District, including 6 terrestrial plants, 6 aquatic plants, and 1 invertebrate. Among these species, the Canada goldenrod (Solidago canadensis L.), Fuchsia snail, Great wolf loosestrife, and Pleasant drought lotus grass have an intermediate risk rating, indicating greater danger. Based on the results, we propose a series of control strategies, including strengthening the protection of forest and wetland resources and enhancing the prevention and control of key areas and key species. These strategies will help protect the ecological and biological security of Yuhang District.展开更多
