WRiMS terminology
Invasiveness
| Invasiveness |
Definition with respect to an introduced species |
| Invasive |
Spreading geographically, or where scientific evidence of negative impacts on native biodiversity have been recorded |
| Invasiveness not specified |
Invasiveness has not been specified or evidence of impact is not clear |
| Invasiveness uncertain |
Invasiveness is uncertain and evidence of impact is not clear |
| Uncertain management |
Species is being managed to prevent introduction and/or spread |
| Not invasive |
Which have not naturalised, not spread, or not shown to have impacts on native biodiversity |
| Of concern |
Species that have not displayed any invasiveness in the country or sea area where they have been introduced, but are known to be
invasive in their introduced range elsewhere; and whose life stage forms can be dispersed through ballast water and or hull fouling; |
Origin
Self-explanatory terminology
- Alien
- Native
- Native endemic
- Native non-endemic
- Origin uncertain
- Origin unknown
Location
- Introducted country and/or sea area
- Native country and/or native sea area
- Source country and/or sea area
Occurrence
- Absent
- Border intercept
- Detected in invasion pathway
- Detected in the wild
- Eradicated
- Eradication unconfirmed
- Established
- Established and expanding
- Established and stable
- Extirpated
- In captivity/cultivated
- Introduction unverified
- Occurrence not specified
- Present/controlled
- Recorded in error
- Reported
- Sometimes present
Impact
- Adverse habitat modification
- Alters bio-geochemical/hydrologic cycles
- Alters trophic interactions
- Aquatic transport
- Consumes native species (predator or herbivore)
- Damage to marine structures or archaeology
- Genetic impacts: hybridisation and introgression
- Human health
- Induces novel behavioural or eco-physiological responses
- Loss of aquaculture/commercial/recreational harvest or gain
- Loss of public/tourist amenity
- Other impact - undefined or uncertain
- Outcompetes native species for resources and/or space
- Pathogen/parasite or carrier of a pathogen/parasite
- Water abstraction or nuisance fouling
Pathways and vectors
- Aquaculture: accidental
- Traits:Pathways/vector
- Bio-control:
- accidental translocation with deliberate bio-control release
- deliberate translocation as a bio-control agent
- Canals: natural range expansion through man-made canals
- Debris: transport of species on human generated debris
- Fisheries:
- accidental as bait
- accidental with deliberate translocations of fish or shellfish
- accidental with fishery products, packing or substrate
- deliberate translocations of fish or shellfish to establish or support fishery
- Individual release:
- accidental release by individuals
- deliberate release by individuals
- Natural dispersal
- Pathway/vector:
- Plant introductions:
- accidental with deliberate plant translocations
- deliberate translocation of plant species
- Recreational equipment: accidental with recreational equipment
- Scientific research:
- accidental release with research activities
- deliberate release with research activities
- Seaplanes: accidental as attached or free-living fouling organisms
- Ships:
- accidental as attached or free-living fouling organisms
- accidental associated with cargo
- accidental with ballast water, sea water systems, live wells or other deck basins
- accidental with solid ballast
- general
