This circular applies to state agencies, organizations, and individuals involved in the investigation, identification, assessment, and issuance of the List of invasive alien species.
Accordingly, the scope of investigation into invasive species includes: the name and biological characteristics of the species; distribution range, habitat, pathways of introduction, establishment of populations, and spread under natural conditions; impacts on biodiversity (native species and ecosystems) and socio-economic factors; and measures for prevention, control, and eradication of invasive alien species.
Methods for investigating invasive alien species: Based on the subject of investigation and the actual conditions of the survey area, agencies and organizations shall decide on appropriate investigation methods to collect primary and secondary data on invasive alien species.
For primary data collection: Methods include observing and recording species along transects, at specific points, or within sample plots; using imaging and audio recording devices, camera traps, light traps, pitfall traps, and automatic monitoring equipment; applying remote sensing technology, satellite imagery, drones, and positioning devices to determine habitats and species distribution.
For secondary data collection: Data is compiled from scientific reports and domestic and international databases on invasive alien species.
Every three years, or as necessary, the Ministry of Agriculture and Environment and provincial-level People’s Committees shall conduct investigations of invasive alien species.
The circular clearly outlines the criteria for determining the risk of invasion by alien species, including:
The ability of alien species to enter Vietnam: Natural entry (via wind, water, animals); human-mediated entry (intentional or unintentional).
The ability of alien species to spread in ecological regions: Reproductive capacity and establishment of populations; dispersal ability of the alien species.
The potential harm caused by alien species: Impact on native species and ecosystems; impact on socio-economic factors.
The list of invasive alien species includes 67 species divided into three groups: The microorganism group includes: root rot fungi, plague-causing bacteria in rats and animals, and banana bunchy top virus. The animal group includes: coconut leaf beetle, mosquito fish, tiger fish, brown trout, smallmouth bass, ermine, cane toad, green crab, crustacean Cercopagis pengoi, big-headed ant, red-eared slider turtle, red swamp crayfish, zebra mussel, and others.
The plant group includes: giant salvinia, Alternanthera philoxeroides, Spanish needle (Bidens pilosa), Prosopis tree, Japanese knotweed, prickly pear cactus, foxtail grass, and others.
Every three years, or as necessary, the Ministry of Agriculture and Environment will revise and supplement the list of invasive alien species.
The circular will take effect from January 15, 2026.
