Aquatic ecosystems

The Northern Territory’s aquatic ecosystems are incredibly diverse and valued for their cultural environmental, economic and social significance.

From the working port of Darwin Harbour and the large tropical river systems of the Top End to waterholes in the Central Australian desert, the management and protection of these wetlands is important to preserve these values for all Territorians.
