| Pathway | Explanation |
|---|---|
| Agriculture | Plants for production of food for human and animal consumption, incl. crops and contaminants of hay, grain, fodder |
| Angling/sport | Live bait or dispersal via fishing gear or/and boats or as a consequence of aquasports |
| Animal husbandry | Animals for production of food for human, including the pest species introduced via the animal hosts |
| Aquaculture | Fish/crayfish/algae/seafood farming, or a consequences of stocking of species (pest species) - includes mariculture |
| Aquaria | Ponds and aquariums |
| Ballast water & sediments | Ballast water and sediments in tanks, as well as solid ballast, incl also the dispersal via shipping in general (eg. Brown rat) |
| Biological control | Introduced as a putative biocontrol agent/pest of another species |
| Escapes | Fur farming, pet-animals escaping from cativity, laboratory animals, animal escapes, pet trade |
| Fisheries | Commercial fishing |
| Forestry | Timber and tree production, including the pest species introduced via tree hosts or product thereof |
| Horticulture | Plants used for ornamental purposes, gardening |
| Hull fouling | Fouling of ships hulls |
| Hunting | Released as hunting quarry or prey |
| Landscaping | The use of plants in the landscape (such as hegde plantings, binding of silt, erosion control) |
| Medicinal | Typically plants (maybe a few animals) for this purpose |
| Not known | |
| Ornamental | Animals used for ornamental purposes auch as colourful slugs and birds in parks etc. |
| Reintroduction | Re-introduction of species that have died out in the country previously |
| Secondary introduction | Introduced species where populations have been introduced from a nearby country/sea area - not the natural distribution area |
| Transport | Infrastructure, translocation of machinery, transportation along roads and rails, planes, package material etc. |
| Status | Explanation |
|---|---|
| Established | The species has formed self-reproducing populations in semi-natural or natural areas. |
| In captivity/culture | Greenhouses, houses and otherwise confined by humans |
| Not established | The species has not formed self-reproducing populations (also called casual or incidental) |
| Not known | |
| Suspected | The species is suspected to be found in the country, but no scientific proof published |
| Within country transfer | The species occurs naturally (is indigenous) within one part of the country but has been introduced by humans into another region where it has not previously occurred. |
| Impact | Explanation |
|---|---|
| Abiotic changes | Modification of fire regime, succession, hydrology, nutrient availability, |
| Competition | Competing with other organisms filling the same niche in the food chain (horizontal effect), physical disturbance |
| Decomposition | Entering the local food web by being a new decomposer (vertical effects) |
| Disease transmission | Being a reservoir for parasites or a vector for pathogen or being a parasite/pathogen |
| Extinction | Extinction of native species - such a grave effect is rarely seen in our parts of the world (let's hope we se no records here) |
| Genetic | hybridising with a related species or varieties, may lead to extinction by gene flow or dilution of locally adapted genepool |
| Herbivory | Entering the local food web by being a new herbivore (vertical effects) |
| Human health | Human health effects by being toxic, causing diseases or allergies |
| None | Preferably (!) based on some kind of scientific knowledge |
| Not known | no information available |
| Predation | Entering the local food web by being a new predator (vertical effects) |
| Resource allocation | Being a new ressource for native or introduced species (for herbivores, predators or decomposers) (vertical effects) |
| Socio-economic | Fouling, clogging of waterways, leading to increased pesticide/herbicide use, control and management costs etc. |
| Toxic | Being toxic for local species, thereby displacing these. |
