“…The species distribution is dependent upon the local soil, flooding regime and logging history. Close to the river the landscape once underwent regular seasonal flooding resulting in the formation of levy deposits, seasonal swamps and wetlands as well as occasional course realignment (Cooling, Lloyd, Rudd, & Hogan, 2002;Rhodes, 1996).…”

“…There is a complex network of seasonal wetlands, depressions and floodways which channel water across the island landscape (Cooling et al, 2002). Prior to controlled flows of environmental water now allocated, Gunbower had been dry for many years, threatening the migratory birds and decreasing the local biodiversity (Cooling et al, 2002;Murray-Darling Basin Authority, 2011). The other remnant forests along the river, such as Guttram Swamp, Barmah, and Nyah, face many of the same challenges as Gunbower with ecological health and cultural protection (Finn & Jackson, 2011;Porter, 2006).…”

“…The flow and flooding information of natural and regulated flows used in the map was obtained from a number of sources (Cooling et al, 2002;Humphries, 2007;Murray-Darling Basin Authority, 2011). The watercourse information used is an amalgamation of two state watercourse datasets.…”

“…The second consideration is the map content. The available environmental and cultural heritage data for Gunbower Island and surrounds is limited and both spatially and temporally patchy (Cooling et al, 2002;Rhodes, 1996). The Barapa field collection of data is focused on targeted areas within Gunbower such as around the larger lagoons and waterways.…”

Barapa Country through Barapa eyes: cultural mapping of Gunbower Island, Australia

The Gunbower Yemurriki Map details important information about Barapa Country and Barapa people for the purpose of education. The Barapa are the Traditional Owners of the lands north and south of the Murray River around Cohuna, Australia and are working with natural resource agencies to identify and map cultural assets on traditional lands, particularly in relation to water resources. The Gunbower Yemurriki Map has been developed through participatory cultural mapping processes to demonstrate the community connection to water and the wider cultural landscape. Yemurriki is the Barapa word for Country. The map developed and presented in this study will be used to educate the local non-indigenous community about Barapa cultural values and to act as a teaching aid for younger Barapa people. The map depicts stories, totems, and places identified within the landscape. All the information included is what the Barapa consider public and educational. ARTICLE HISTORY

Abstract:Australian arid zone ephemeral rivers are typically unregulated and maintain a high level of biodiversity and ecological health. Understanding the ecosystem functions of these rivers requires an understanding of their hydrology. These rivers are typified by highly variable hydrological regimes and a paucity, often a complete absence, of hydrological data to describe these flow regimes. A daily time-step, grid-based, conceptual rainfall-runoff model was developed for the previously uninstrumented Neales River in the arid zone of northern South Australia. Hourly, logged stage data provided a record of stream-flow events in the river system. In conjunction with opportunistic gaugings of stream-flow events, these data were used in the calibration of the model. The poorly constrained spatial variability of rainfall distribution and catchment characteristics (e.g. storage depths) limited the accuracy of the model in replicating the absolute magnitudes and volumes of stream-flow events. In particular, small but ecologically important flow events were poorly modelled. Model performance was improved by the application of catchment-wide processes replicating quick runoff from high intensity rainfall and improving the area inundated versus discharge relationship in the channel sections of the model. Representing areas of high and low soil moisture storage depths in the hillslope areas of the catchment also improved the model performance. The need for some explicit representation of the spatial variability of catchment characteristics (e.g. channel/floodplain, low storage hillslope and high storage hillslope) to effectively model the range of stream-flow events makes the development of relatively complex rainfall-runoff models necessary for multisite ecological studies in large, ungauged arid zone catchments. Grid-based conceptual models provide a good balance between providing the capacity to easily define land types with differing rainfall-runoff responses, flexibility in defining data output points and a parsimonious water-balance-routing model.

As the impacts of climate change and water demands from irrigation continue to increase in the Murray–Darling Basin, water for the environment is becoming more scarce and the ecological conditions of many wetlands is poor. With water scarcity, conservation triage is becoming an increasingly relevant management option for environmental watering of wetlands. However, triage is controversial; being considered contrary to current conservation objectives and practices. We assessed environmental watering at two Ramsar wetlands, Macquarie Marshes and Gunbower Forest, based on international environmental treaty obligations and domestic policy settings, changes to flow regimes, wetland condition and current management. Triage decision making was found to be in tacit use at Macquarie Marshes, based on ‘rules of thumb’ and experiential ecohydrological knowledge, whereas formal environmental watering planning formed the basis for triage decision making at Gunbower Forest. We developed a framework for conservation triage of wetlands in the Murray–Darling Basin to stimulate change in the decision context for wetland conservation and adaptation under climate change. Conservation triage entails reframing of relationships between people and nature and values, rules and knowledge used by stakeholders. Because water is the medium by which wetland conservation outcomes eventuate, trade-offs between competing water uses can be realised with the triage framework.
