OCEAN INFORMATION
NORTHERN TERRITORY
The Northern Territory contains some of the most pristine and ecologically important coastal and marine areas in the Australian tropics. The coastal areas of the Northern Territory are sparsely inhabited apart from around Darwin.
The traditional owners, the Indigenous Australians control 84 percent of the coastline to the low water mark and are increasingly sharing their traditional knowledge of "saltwater country"
What's it like?
Darwin Harbour is a tropical estuary, covering approximately 450 square kilometres. It has 23 square kilometres of mangrove and saltmarsh communities. Darwin is lucky enough to be one of the few cities in the world with a large area of mangroves on its doorstep.
What lives here?
As well as supporting all kinds of bird, fish, shellfish and plant life the mangroves act as a protection against flood damage during extra high tides and cyclones.
Darwin Harbour is home to five kinds of sea turtles, the peaceful dugong that feeds on seagrasses and the elusive Irrawaddy River Dolphin. The harbour contains more than 100 kinds of coral and hundreds of different kinds of sponges.
What are the problems?
Pollution from increasing development
Clearing of mangroves
Degradation of the harbour environment
What are the solutions?
The need for more ocean research in the Northern Territory is urgent. Accurate maps of marine habitats are needed to help identify sensitive areas and areas of high conservation value.
