【Objective】This study aims to investigate the current status of invasive alien species in the forest, grassland, and wetland ecosystems of Huaihua City, providing fundamental data for developing effective prevention and control strategies to protect the ecological and biological security of the region. 【Method】Through a comprehensive survey of invasive alien species in the forests, grasslands, and wet- lands of Huaihua City, we have initially ascertained the current status of alien species invasion which covers the entire city, involving multiple ecological types, including plants, pathogenic microorganisms, insects, invertebrates, and vertebrates. 【Result】The survey results show that a total of 95 invasive alien species are discovered in Huaihua City. Among them, there are 85 plant species, 1 pathogenic microor- ganism, 1 insect species, 2 invertebrate species, and 6 vertebrate species. Among these species, 21 are invasive alien species under key management, such as Bursaphelenchus xylophilus ( Pine Wood Nematode) and Solidago canadensis ( Canada Goldenrod). 【Conclusion】Based on the results, we propose a series of prevention and control measures, including strengthening regular monitoring, enhan- cing the prevention and control of invasive alien species under key management, scientifically managing and restoring the ecological environment, fully utilizing the survey results, ensuring investment in preven- tion and control funds, and strengthening the promotion of the hazards of invasive alien species. The im- plementation of these measures will help reduce the threat of invasive alien species to the ecosystem of Huaihua City and maintain ecological and biological security.
