  • Updated description of Vegetation Survey of Groote Eylandt 2018 from

    This spatial dataset provides polygon information delineating vegetation community boundaries at a scale of approximately 1:50 000 and covers Groote Eylandt and other islands in the Groote archipelago, including Bickerton and Winchelsea. The study area covers approximately 261 025 ha, excluding 718 089 ha mapped as ocean, and is within the Groote subregion of the Arnhem Coastal Bioregion. The primary purpose of the project was to produce vegetation and habitat mapping for Groote Eylandt and other islands in the Groote archipelago, at an appropriate scale for the management of environmental assets within the Anindilyakwa Indigenous Protected Area. The dataset describes vegetation communities at four levels in accordance the NT National Vegetation Information System mapping (NRETAS, 2007), including Class, Structural Formation, Broad Structural Formation and Sub-Formation.

    This spatial dataset provides polygon information delineating vegetation community boundaries at a scale of approximately 1:50 000 and covers Groote Eylandt and other islands in the Groote archipelago, including Bickerton and Winchelsea. The study area covers approximately 261,025 ha, excluding 718,089 ha mapped as ocean, and is within the Groote subregion of the Arnhem Coastal Bioregion. The majority of vegetation sites were surveyed in 2018. Version 1 was published in 2021. Version 2 (this version) incorporates additional field data collected by the Department of Lands, Planning and Environment and GEMCO between 2018 and 2024. Polygon boundaries have been revised and updated to reflect additional data. The primary purpose of the project was to produce vegetation and habitat mapping for Groote Eylandt and other islands in the Groote archipelago, at an appropriate scale for the management of environmental assets within the Anindilyakwa Indigenous Protected Area. The dataset describes vegetation communities at four levels in accordance the NT National Vegetation Information System mapping (NRETAS, 2007), including Class, Structural Formation, Broad Structural Formation and Sub-Formation. CAUTION: Polygon boundaries were derived using Sentinel-2 satellite image data (2018 annual composite, 10m spatial resolution). When assessing specific areas within the mapping it is recommended a site inspection is undertaken to establish unmapped variation and confirm mapping accuracy on the ground. Although field information has been incorporated into the development of this data, the final dataset has not been validated. Users are advised that attribute accuracy varies over the study area.
