Methods: We conduct the first detailed mapping of habitat change in two of the largest forested wetlands in inland Australia, comparing wet and dry hydrological phases. Detailed photogrammetry, supported by extensive ground survey, allowed the interpretation of high resolution aerial photography to vegetation community level. Results: We found a consistent pattern of decline in non-woody vegetation, particularly amongst grasses utilising the C₄ photosynthetic pathway. The C₄ grasses Pseudoraphis spinescens and Paspalum distichum showed steep declines in the Barmah Millewa and Macquarie Marshes respectively, being replaced by River Red Gum E. camaldulensis. C₃ sedges proved more resilient in both systems. Conclusions: Our results suggest that a pattern of tree expansion into non-woody wetland vegetation, characteristic of wetlands across the globe, is a major habitat structural change in the Australian floodplain wetlands studied. Projected hydrological impacts of climate change are likely to further restrict wetland grass foraging habitat in these semi-arid floodplain wetlands.]]> Tue 09 Aug 2022 14:59:18 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:43009 Fri 09 Sep 2022 14:46:25 AEST ]]>
