Natural values of the Gregory Basin
The Gregory Wild River Area has the following relevant natural values:
- hydrologic processes
- geomorphic processes
- water quality
- riparian function
- wildlife corridor function.
The river systems in the area are in near natural condition due to low levels of development in their catchments. For example, there are no large towns, no major dams and about 15 per cent of the area is protected in national parks and other conservation areas. The extensive riparian vegetation preserves bank stability and provides habitat for plants and animals.
The river’s natural flow is reflected by:
- the extent and natural integrity of permanent to seasonal wetlands, stream channels, deep pools and other aquatic habitats within the area
- diversity of waterbirds and migratory birds that live in the area
- the diversity of fish species in the area—a recent survey recorded thirty different fish species (including three unique species).
The wild river area has a number of special features that play a significant role in maintaining wild river natural values. These special features, which include nationally significant wetlands, are strongly connected to the river systems. Preserving these features is an important part of maintaining the wild river area’s natural values. The special features of the Gregory Wild River Area are:
- Musselbrook Creek Aggregation
- Bluebush SwampThorntonia Aggregation (Lawn Hill Gorge) Gregory River
- Lower Gregory/Lawn Hill Floodplain Complex.
