    Abstract


    Research on introduced land snails was carried out from 2012 to 2020 in Northwest Vietnam (Lai Chau, Lao Cai, Dien Bien, Son La, Yen Bai, and Hoa Binh Provinces). A total of nine species (nearly 4.5% of the total number of land molluscs species in the research area) representing eight genera and five families were enumerated based on field surveys of 91 sampling sites. Five species (Lissachatina fulica, Allopeas gracile, Sarika resplendens, Bradybaena similaris, Succinea tenuis) were recorded frequently disturbed in habitats, while three species (Allopeas clavulinum, Chalepotaxis infantilis, Gulella bicolor) in relatively undisturbed habitats, and a species (Ganesella perakensis) in natural habitats. Of these, three species were considered to cause low risks (Allopeas clavulinum, Chalepotaxis infantilis, Ganesella perakensis), two medium risks (Gulella bicolor, Succinea tenuis), and four high risks (Lissachatina fulica, Allopeas gracile, Sarika resplendens, Bradybaena similaris). This paper’s data is urgently required to identify and manage introduced land snail species and if possible to prevent their spread to noninfected areas in Vietnam.
