1.1.1.1 Definitions used

The Clarence-Moreton bioregion only includes the eastwards draining part of the Clarence-Moreton Basin (based on surface water flow delineation), comprising the area east of the Great Dividing Range in eastern Australia. The section of the Clarence-Moreton Basin west of the Great Dividing Range forms part of the Northern Inland Catchments bioregion (Figure 3). The Clarence-Moreton Basin contains substantial coal resources. The major stratigraphic units that have in the past been targeted for coal mining are the Walloon Coal Measures, which extends over most of the basin, and to a lesser extent the Ipswich and Nymboida coal measures (more detail in Section 1.1.3). The Walloon Coal Measures also are the major target in the Clarence-Moreton Basin for coal seam gas exploration.

The boundary between the Clarence-Moreton bioregion and the Northern Inland Catchments bioregion is defined on the basis of an assessment of river basins, coal basins and natural resource boundaries, as outlined in the Methodology for bioregional assessments of coal seam gas and coal mining development on water resources (Barrett et al., 2013).

Only those sections of the Clarence river basin and Brisbane river basin which overlap with the Clarence-Moreton Basin are part of the Clarence-Moreton bioregion (Figure 4).

The Clarence-Moreton bioregion includes parts of two natural resource management regions: South East Queensland Catchments and North Coast Local Land Services (Section 1.1.6 and Section 1.1.7).
