The classification of pathways of introduction currently used by EASIN largely follows the framework proposed by Hulme et al. (2008). Five main pathways have been included (each one divided into more specific sub-categories): 1. Contaminant (Trade of contaminated commodities; Packaging materials; Aquaculture); 2. Corridor (Lessepsian migrants; Inland canals; Railroads and Highways); 3. Escape (Pets, Terrarium-Aquarium species; Zoos, botanical gardens; Cultivation and Livestock; Aquaculture; Ornamental planting; Use of live food-bait); 4. Release (Biocontrol; Game animals; Landscaping-Erosion control; Pets, Terrarium-Aquarium species; Other); 5) Stowaway (Shipping; Aviation; Land transport).
EASIN will gradually align its pathways categorization to the one proposed by the Convention of the Biological Diversity (CBD 2014. Pathways of introduction of invasive species, their prioritization and management. UNEP/CBD/SBSTTA/18/9/Add.1, Montreal, Canada, 23-28 June 2014, 18 pp.), aiming at achieving synchronization and harmonizing of information on Alien Species pathways.
