Dataset: Receptors for the Galilee subregion



The dataset was derived by the Bioregional Assessment Programme from multiple source datasets. The source datasets are identified in the Lineage field in this metadata statement. The processes undertaken to produce this derived dataset are described in the History field in this metadata statement.

The receptor register for the Galilee subregion contains a total of 1,171,269 receptors, comprising 1,166,875 receptors assigned to ecological and sociocultural assets combined and 4,394 receptors assigned to economic assets (Bioregional Assessment Programme, Dataset 1). Receptors have been assigned across all 41 landscape classes defined for the subregion. Assignment of receptors to specific landscape classes provides a basis for grouping receptors on the basis of shared conceptual models for testing of hydrological responses and ecological, economic and/or sociocultural impacts. The mean density of receptors representative of ecological and sociocultural asset types across the Galilee preliminary assessment extent (PAE) is one receptor per 52.5 ha. Mean density of receptors varies among the 41 landscape classes, from one receptor per 0.14 ha to one receptor per 764 ha. The range of receptor density is primarily due to a combination of two interacting factors: (i) the different methods used to assign receptors to landscape classes represented by points (springs), lines (streams) and polygons (all other classes), and (ii) the inherently different patchiness of each landscape class within the landscapes of the PAE. The mean density of receptors is higher for springs (points) and streamlines (linear features) than for areas of vegetation mapped as polygons. The mean density of receptors is also higher for the non-remnant landscape classes than their equivalent remnant landscape classes.

Dataset History

Model nodes were positioned to represent areas of identified assets eg clusters of bores, GDE's, stream confluence points and river reaches. A receptor point represents one or more assets.

Most of model nodes are located in the alluvium, the majority of which are associated with groundwater-dependent ecosystems with one model node assigned to a town water supply. The Ronlow beds, which are part of the Eromanga Basin, have two model nodes associated with springs. There are 13 model nodes associated with the Clematis Group and they include groundwater-dependent ecosystems, licensed groundwater extractions, monitoring bores, springs and a town water supply. The Rewan Group has a single model node, which is a monitoring bore. The upper Permian coal measures have five model nodes, which are two groundwater licences and three springs.
