Abstract
The dataset was derived by the Bioregional Assessment Programme. This dataset was derived from multiple datasets. You can find a link to the parent datasets in the Lineage Field in this metadata statement. The History Field in this metadata statement describes how this dataset was derived.
An asset is an entity having value to the community and, for bioregional assessment purposes, is associated with a bioregion. A bioregion is a geographic land area within which coal seam gas and or coal mining developments are, or could, take place and for which bioregional assessments are conducted. A water-dependent asset has a particular meaning for bioregional assessments; it is an asset potentially impacted by changes in the groundwater and or surface water regime due to coal resource development. Some ecological assets are solely dependent on incident rainfall and will not be considered as water dependent if evidence does not support a linkage to groundwater or surface water. The water-dependent asset register is a simple and authoritative listing of the assets within the preliminary assessment extent (PAE) that are potentially subject to water-related impacts. A PAE is the geographic area associated with a bioregion or subregion in which the potential water-related impact of coal resource development on assets is assessed. The compiling of the asset register is the first step to identifying potentially impacted assets, which is the goal of the overall bioregional assessment.
Information about entities having value to the community and that might be affected by waterrelated impacts of coal seam gas (CSG) and large coal mining development is collated from a range of sources into a table of assets within the asset database. There are three types of assets: (i) ecological, (ii) economic and (iii) sociocultural. Many ecological and sociocultural assets were obtained from state and national sources.
Generating the water-dependent asset register requires the development of a comprehensive georeferenced relational database known throughout this submethodology as the asset database. The asset database holds all assets compiled for a BA and the register lists the subset of assets that meet the water dependency criteria, as defined in Section 4. As there may be many assets within each asset class for each bioregion or subregion, each asset must have a unique identifier (AssetID). A single asset is represented spatially in the asset database by single or multiple spatial features (point, line or polygon). Individual points, lines or polygons are termed 'elements' and must also have a unique identifier (ElementID). An element is a spatially discrete unit and is recorded individually in the element tables.
Assets can be made up of one or more elements. Elements are linked to assets in the database via the 'Element_to_asset' table (see Appendix Table A.2 in CompilingWaterDependentAssets.pdf in AnR_Documentation folder). An example of the relationship between assets and elements is given in Figure 5 which shows that the asset (Coolibah-Black Box Woodlands of the Darling Riverine Plains and the Brigalow Belt South Bioregions, listed within the EPBC Act as a threatened ecological community) is composed of 3453 elements.
Please note 58 assets were merged to an associated asset which resulted in their AID data being removed from the asset table. The assets which were merged had been previously provided with a classification which did not match the classification in MO2.In addition 121 Groundwater element and 49 Surface water elements were added to the Namoi asset list. 151 of 170 new elements were grouped to 14 new assets while 19 of 170 new elements were merged to associated assets.
Purpose
For creation of asset list for bioregional assessment
