Highlights

Activities

With no delivery of water for the environment into Koondrook Perricoota Forest in 2018-19, all 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 stressed and there is little groundcover and very few wetland plants.

Community

Turtles are of cultural significance to the Yorta Yorta and Barapa Barapa local First Nations. Now in its third year, Traditional Owners working on Country have undertaken a pest management program that has successfully protected turtle nests from foxes in the forest.

Vegetation

Water plants thrived in the Pollack wetland, in response to the delivery of small amounts of water for the environment over the last three years. Duck weed, water ribbons, reeds and rushes responded well, providing important habitat for native fish and waterbirds. This is in stark constrast to the rest of Koondrook Perricoota Forest floodplain with many dry wetlands with no aquatic plant life, limited understorey plants and stressed river red gums.

Waterbirds

In a dry landscape, the delivery of a small amount of water for the environment to the Pollack wetland is providing an important refuge for waterbirds. The 2018 survey recorded 14 waterbird species at the Pollack. The Australasian darter and the little pied cormorant successfully bred for the second consecutive year.

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.
