When the River Runs Dry: Human and Ecological Values of Dry Riverbeds
CONCEPTS AND QUESTIONS 202 When the river runs dry: human and ecological values of dry riverbeds Alisha L Steward1,2*, Daniel von Schiller3, Klement Tockner4, Jonathan C Marshall1, and Stuart E Bunn2 Temporary rivers and streams that naturally cease to flow and dry up can be found on every continent. Many other water courses that were once perennial now also have temporary flow regimes due to the effects of water extraction for human use or as a result of changes in land use and climate. The dry beds of these temporary rivers are an integral part of river landscapes. We discuss their importance in human culture and their unique diversity of aquatic, amphibious, and terrestrial biota. We also describe their role as seed and egg banks for aquatic biota, as dispersal corridors and temporal ecotones linking wet and dry phases, and as sites for the storage and processing of organic matter and nutrients. In light of these valuable functions, dry riverbeds need to be fully integrated into river management policies and monitoring programs. We also identify key knowledge gaps and suggest research questions concerning the values of dry riverbeds.

Estuarine Wetlands
ESTUARINE WETLANDS • An estuary occurs where a river meets the sea. • Wetlands connected with this environment are known as estuarine wetlands. • The water has a mix of the saltwater tides coming in from the ocean and the freshwater from the river. • They include tidal marshes, salt marshes, mangrove swamps, river deltas and mudflats. • They are very important for birds, fish, crabs, mammals, insects. • They provide important nursery grounds, breeding habitat and a productive food supply. • They provide nursery habitat for many species of fish that are critical to Australia’s commercial and recreational fishing industries. • They provide summer habitat for migratory wading birds as they travel between the northern and southern hemispheres. Estuarine wetlands in Australia Did you know? Kakadu National Park, Northern Territory: Jabiru build large, two-metre wide • Kakadu has four large river systems, the platform nests high in trees. The East, West and South Alligator rivers nests are made up of sticks, branches and the Wildman river.

Into Queensland, to Within 45 Km of the Georgina River Floodout Complex
into Queensland, to within 45 km of the Georgina River floodout complex. As a consequence, it is correctly included in the Georgina Basin. There is one river of moderate size in the Georgina basin that does not connect to any of the major rivers and that is Lucy Creek, which runs east from the Dulcie Ranges and may once have connected to the Georgina via Manners Creek.
