In the Lachlan Catchment there are also nine regionally significant wetlands, four in the mid-Lachlan between Forbes and Lake Cargelligo (including Lake Cargelligo itself) and five below Lake Cargelligo. Regionally significant wetlands are recognised in part on the basis of their meeting one of the five criteria below, which was developed for identifying a key (or priority) environmental asset in the Murray–Darling Basin Plan process (MDBA, 2011b).
- Water-dependent ecosystems of formally recognised significance (this includes JAMBA/CAMBA/ROKAMBA);
- Natural or near-natural, rare or unique water-dependent ecosystems;
- Water-dependent ecosystems that provide critical habitat;
- Water-dependent ecosystems that support threatened species and communities; and
- Water-dependent ecosystems that support significant biodiversity.
