Highlights

Activities

With no delivery of water for the environment into Koondrook Perricoota Forest in 2018-19, most of the wetlands, creeks and waterholes are dry. Only a handful of lagoons near the river still hold a small amount of water. Red gums are increasingly stressed and there is almost no groundcover and very few wetland plants.

Community

It is important to understand how grazing pressures can impact the recovery of wetland plants. At Myloc wetland, Barapa Barapa Traditional Owners installed fencing to exclude terrestrial grazers in order to measure the response of wetland plants to water, without the disturbance from these animals.

Vegetation

Water plants thrived in the Pollack wetland which has received small amounts of water for the environment over the last four years. Six native species including pondweed and bulrush were found for the first time in over a decade of monitoring. This is in stark contrast to the rest of the floodplain with many dry wetlands containing no aquatic plant life, limited groundcover and stressed river red gums. Nine different water plant species thriving at the Pollack wetland. (Photo: Jean Dind, FCNSW)

Waterbirds

The Pollack continues to provide an important refuge for waterbirds in a very dry landscape, containing 45% of all waterbirds observed in the forest. There was evidence of breeding for twelve species of waterbirds including the sacred kingfisher, Pacific black duck and the Australasian grebe. Reed warbler nest at Pollack Lagoon.

Fish

Drying wetlands within Koondrook-Perricoota forest are placing the fish community under increasing stress. Where there are wetlands with some deeper water, the pools are providing important shelter for small-bodied native fish. Nine small native fish species were found including the Murray-Darling rainbowfish and the threatened unspecked hardyhead.Pollack Lagoon (Photo: Jean Dind, FCNSW)

Each year, water is released into the environment depending on the climatic conditions. See the outcomes of water over time for a long-term view of how natural and released water affects the health of rivers.
