Column name | Description | Values |
|---|---|---|
scientificName | *The binomial name of the species or taxon including the authority as per Global Biodiversity Information Facility (GBIF) https://doi.org/10.15468/39omei accessed 20 May 2020. | Character |
vernacularName | *The English name by which a species is known to the general public in South Africa. | Character |
family | *The full scientific name of the family in which the taxon is classified. | Character |
fingdom | *The full scientific name of the kingdom in which the taxon is classified. | Character |
phylum | *The full scientific name of the phylum or division in which the taxon is classified. | Character |
class | *The full scientific name of the class in which the taxon is classified. | Character |
isNative | This specifies whether the species or taxon is native to South Africa or not. | Factor with three levels: Cryptogenic, TRUE, FALSE |
occurrenceStatus | *This specifies whether the species or taxon has a native-alien population in South Africa. | Factor with four levels. Absent, Present, Doubtful, NotEvaluated |
degreeOfEstablishment | *The coding as taken from the Unified Framework for Biological Invasions19, with the wording and description as per Groom et al.16. | Factor with 12 levels: A0, A1, B1, B2, B3, C0, C1, C2, C3, D1, D2, E |
IntroductionStatus | A less refined measure of degree of establishment that consolidates several categories in degreeOfEstabishment | Factor with five levels: Casual; Established; Colonising; Invasive; WidespreadInvasive |
pathway | *The process by which an organism came to be in a given place at a given time. | Factor with six major categories, and 44 sub-categories. |
FirstRecord | The year the native-alien population was first recorded | Numeric |
NativeRangeBroadAdmin | Provinces where the species occurs naturally in South Africa. This lists the occupancy of specific administrative regions in South Africa (the nine provinces for terrestrial systems; 22 water management areas for freshwater systems; and seven marine ecoregions). | Factor with 38 levels |
AlienRangeBroadAdmin | Province where the species has formed population(s) outside its native range and outside of captivity or cultivation in South Africa. This lists the occupancy of specific administrative regions in South Africa (the nine provinces for terrestrial systems; 22 water management areas for freshwater systems; and seven marine ecoregions). | Factor with 38 levels |
NativeRangeBroadEcol | Biomes where the species occurs as a native in South Africa. | Factor with eight levels: Fynbos, Nama-karoo, Albany-thicket, Savanna, Grassland, Indian Ocean Coastal Belt, Forest, Succulent-karoo biome |
AlienRangeBroadEcol | Biomes where the species occurs as an alien in South Africa. | see NativeRangeBroadEcol |
NativeRangeFreeText | Sites where the species occurs naturally. | Character |

impactEICAT Global | The maximum current recorded environmental impact anywhere in the world20,32. This is included here to give an indication of which taxa are known to cause damage. | Factor with seven levels: Minimal Concern, Minor, Moderate, Major, Massive, Not Evaluated, Data Deficient |
impactSEICAT Global | The maximum current recorded socio-economic impact anywhere in the world21. This is included here to give an indication of which taxa are known to cause damage. | Factor with seven levels: Minimal Concern, Minor, Moderate, Major, Massive, Not Evaluated, Data Deficient |
