Koondrook–Perricoota highlights for 2016–17


Traditional owners implemented a program to protect turtle nests from foxes. The program was successful and protected turtle nests within the forest.


The Forest is an important site for waterbird breeding. This year’s natural floods provided the ideal habitat for the first colonial waterbird breeding event in the Forest in over 20 years. Over 1,000 birds from 15 species successfully fledged their chicks. Among them were a large number of wading birds such as Nankeen Night-herons, White-necked Herons and Intermediate Egrets.


Delivery of water triggered a large waterbird breeding event at the Pollack wetland. The release of the water topped up natural flooding and helped Egrets finish their nesting cycle. These birds are rarely seen nesting in this region so this was an exciting result.

Native vegetation

While the River Red Gum forest responded well to natural floods in 2010 and 2016, the health has declined in between  these events due to lack of waterings (natural or delivery of water for the environment). It is expected that the condition of River Red Gums will again decline without follow up watering.

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.

Current activities

Inundation of Koondrook–Perricoota Forest is not planned for 2018/19.

A small amount of water for the environment is planned to be delivered to the Pollack wetland in spring 2018. This provides important habitat for waterbirds, and in 2017 herons and darters were recorded breeding at the site.
