Table 1 Derivation of landsystem units. Vegetation follows the classification of Wilson et al. (1991).
Landsystem Type | Criteria |
|---|---|
Plateau | Lying at an elevation above 180 m in the region of the Arnhemland Plateau or consisting of the Wilson et al. vegetation unit “Allosyncarpia ternata closed forest.” |
Rolling hills | Regions consisting of Wilson et al. vegetation unit “E. dichromophloia, E. miniata low open-woodland with Plectrachne pungens open-hummock grassland understorey” or localized distinct vegetation polygons adjacent to E. dichromophloia and generally following a higher elevation contour (over 90 m). |
Floodplain | Regions consisting of the following Wilson et al. vegetation units: • Mangal low closed-forest (Mangroves) • Melaleuca forest (Paperbark Swamp) • Melaleuca viridiflora, Eucalyptus low open-woodland with Chrysopogon fallax grassland understorey • Mixed closed-grassland/sedgeland (Seasonal Floodplain) • Saline tidal flats with scattered chenopod low shrubland (Samphire) |
Lowland | Regions consisting of the following Wilson et al. vegetation units and lying at low elevation (below 90 m): • Eucalyptus miniata woodland with grassland understorey • E. papuana, E. polycarpa woodland with grassland understorey • E. tectifica, E. latifolia woodland with Sorghum grassland understorey • E. tetrodonta, E. miniata, E. bleeseri woodland with Sorghum grassland understorey • E. tintinnans low woodland with Sorghum grassland understorey. • Coastal dune complex. |
