Important wetland sites
The Lachlan valley includes 3 sites listed on the Directory of Important Wetlands in Australia:
- Great Cumbung Swamp
- Lachlan Swamp
- Booligal Wetlands.
Below Wyangala and Carcoar dams, the catchment’s lowlands are recognised as an endangered ecological community.
Other significant wetlands in the catchment include Merrowie Creek Wetlands, Lake Brewster and Lake Cowal.
Managing water for the environment
The Lachlan River experiences highly variable flows. The NSW Department of Climate Change, Energy, the Environment and Water manages the delivery of water for the environment when and where conditions allow to provide feeding and breeding habitat for a range of wildlife. This is done in consultation with the Lachlan Environmental Water Advisory Group (EWAG).
Management of water for the environment supports the recovery and maintenance of a diverse range of plant communities including black box, river cooba, common reed and extensive areas of riparian fringing river red gum forest and the native animals that use these habitats. This management is done in consultation with the Lachlan EWAG.
Monitoring of water for the environment delivered after the flood of 2012 revealed the return of the threatened Southern bell frog, which had been undetected in the valley for more than 30 years.
Bird species
The Lachlan valley provides habitat for a number of birds listed under international migratory bird agreements, including:
- great egret
- glossy ibis
- sharp-tailed sandpiper
