The survey area covers approximately 260 km2 and is located 10km east of Darwin. On-ground surveys were undertaken in 2013 and mapping is considered suitable to use at a scale of 1:10,000. The Howard Plains SOCS area is recognised as being of international significance due to the concentration of threatened species. A focus of the study was to identify areas that are important for conservation, including sensitive sandsheet heath, the carnivorous plant genus Utricularia and threatened herb Typhonium taylori. Twenty- one vegetation communities are described and mapped.

The datasets have not been updated since publication. There may be a high degree of inaccuracy when comparing this data to the present day extent of this vegetation type.0not knownThe attribute naming format uses 10 characters with no spaces to be suitable for an ESRI shape-file format. An alias attribute name is applied for storage in an ESRI file geo-database format. Polygons have been assigned values for the attributes described in the data dictionary in this metadata record.0Visual interpretation of aerial photography flown in June 2010 was undertaken to delineate vegetation communities in the seasonally saturated floodplains of the Howard River catchment. An iterative process of image interpretation and field survey to ground truth the observed patterns was carried out in the late wet season and early dry season. Vegetation was quantified in 20m by 20m plots to provide floristic and structural data. These data were combined with pre-existing plot data held by the Northern Territory Herbarium in the Vegetation Site Database (VSD) to compile descriptions of the vegetation communities
