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:41238 Sat 30 Jul 2022 12:19:31 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:11159 0.4 above the Australian height datum (mAHD), whereas mangrove occupied areas with spring tidal range >0.3 m, hydroperiod <0.45 and elevation <0.4 mAHD. By using these parameters, it is possible to exclude mangrove from saltmarsh areas and to establish saltmarsh at lower elevations in the tidal frame than would occur under natural conditions, effectively expanding saltmarsh area. These measures can be useful where landward migration of estuarine communities is restricted by infrastructure; however, they should not be considered a substitute for conservation of remnant saltmarsh or establishment of landward buffer zones.]]> Sat 24 Mar 2018 08:08:32 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:17280 Sat 24 Mar 2018 08:01:49 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:25569 Sat 24 Mar 2018 07:35:16 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:25097 Sat 24 Mar 2018 07:15:03 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:31419 Mon 02 Mar 2020 14:10:50 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:40534 Fri 22 Jul 2022 15:19:29 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:47221 Fri 16 Dec 2022 10:16:32 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:43009 Fri 09 Sep 2022 14:46:25 AEST ]]>
