River experts believe that a two-tiered approach to monitoring river health in the wet-dry tropics is required. In this short video Professor Michael Douglas talks about some of the challenges of monitoring river health across such a vast and sparsely populated landscape.

Any plans to build dams in northern Australia need to be very carefully considered in terms of the trade-offs involved. In this short video Professor Stuart Bunn and Associate Professor Michele Burford discuss the implications of building dams in light of research carried out by the Tropical Rivers and Coastal Knowledge research program.

Australia’s tropical rivers are globally significant. They represent one of the largest free-flowing networks of rivers, and they flow through the world’s largest area of high quality tropical savanna. Watch this video to find out more about the research of the Tropical Rivers and Coastal Knowledge program, and the current state and future challenges facing Australia’s tropical rivers.

Researchers have identified gamba grass and other invasive weeds as a potential threat to landholder involvement in environmental offset programs such as the Carbon Farming Initiative.

Strategic savanna burning is one way to reduce Australia’s carbon emissions and create new markets in northern Australia, but the increased fuel load and emissions from weed infestations could make it unfeasible.

A team of researchers from the Northern Australia Hub, in collaboration with Kakadu National Park staff and Traditional Owners, has been investigating aquatic biodiversity on the rivers and floodplains. In August 2012, the researchers collected samples of algae, insects and fish from 20 sites across Kakadu using sweep nets, plankton filters and electrofishing. They are now analysing the chemical signature of these samples to determine food web links between rivers, floodplains and estuaries.

This research will provide a better understanding of the importance of floodplains to freshwater biodiversity across the north, and inform water resource management. For example, by helping to determine where fish and other animals get their food for growth and reproduction.
