Nocoleche Nature Reserve was created to protect a nationally important network of river channels, wetlands and floodplains. Nocoleche is Baakandji and Budjiti country. The Paroo River runs through the centre of the reserve and once formed a meeting ground. It remains one of a few rivers in the Murray-Darling Basin that has little or no interference with its natural flow.
The wetlands are important breeding and feeding ground for large populations of water birds. Recorded native fauna includes 176 bird species, 17 mammals, 37 reptiles, 15 frogs and five types of fish. vast woodlands and shrublands spread across the channels, floodplains, sandplains and low stony tablelands.
