The Lower Murray


The Lower Murray - centred around the Chowilla-Lindsay-Wallpolla Floodplain including the Riverland Ramsar Site, and potentially including adjacent floodplain systems and river reaches

The Chowilla-Lindsay-Wallpolla floodplain and adjacent area is identified as a key research area for the MDB EWKR project. This area is recognised for its size, environmental significance and the scale of previous investment into data collection, monitoring and research.

The Chowilla-Lindsay-Wallpolla floodplain covers an area of approximately 43,856 ha. The area follows the Murray River across New South Wales, Victoria and South Australia,   including the Riverland Ramsar site (Figure 1).

The Chowilla-Lindsay-Wallpolla floodplain area supports aquatic, riparian, floodplain and estuarine habitats including Ramsar-listed wetlands and a diversity of ecologically valuable species. There are more than 20 ecological vegetation classes ranging in conservational significance from ‘least concern’ to ‘endangered’ (Ecological Associates, 2007). A total of 28 threatened wetland plant species have been recorded on Lindsay Island in Victoria (SKM 2003) (MDBA, 2012a).

The area provides valuable habitat for native fish populations such as Murray cod and many fish that are of conservation significance including Silver perch, Macquarie perch, Trout cod, Freshwater catfish, Murray hardyhead and Southern pigmy perch (Davies et al. 2008).

Although there are water delivery constraints that affect environmental watering management (MDBA 2012a), environmental infrastructure at some sites will provide opportunities to explore some research questions through the MDB EWKR program.

The MDB EWKR vegetation and fish themes will be undertaking on-ground research at the Chowilla-Lindsay-Wallpolla floodplain and adjacent area in 2017.
