Alluvium deposits fromthe Cainozoic period gave rise to the red brown earths,cracking clays and texture contrast soils. The soils supportRiverine Grassy Forest and Riverine Grassy ChenopodWoodland ecosystems.Average annual rainfall across the bioregion: 300 mmDaily mean temperature across the bioregion: 15-18˚CLAND USE HISTORYDue to fl ooding, much of this bioregion is unsuitablefor agricultural purposes other than grazing. Extensiveareas of what is now the Hattah-Kulkyne National Parkwere used for grazing and much of the local timber washarvested for fencing. Today, some grazing still occurs butthe majority of agricultural activities are growing grape,almond and citrus crops. The Murray River is a populararea for recreational activities with camping a predominantactivity along the river frontages during the holiday periods.10,0005,00000 5 10 15 20Landscape context scoresPublic land median score – 15.7Private land median score – 14.5[Statewide median score – 14.9]109
