Manning River Estuary Catchment and Management Program 2021-2031

Page 152

Table 8: Recommended Research Program

• Undertake a bathymetric survey combined with hydrodynamic and water quality monitoring at key locations within the lower catchment/estuary and develop a baseline condition hydrodynamic and water quality model for all future research and planning. • Fine-scale prioritisation of coastal wetlands for conservation based on size, perimeter to area ratio, condition, pressures, extent within the catchment and more broadly in NSW, as well as listing status • Finalise development of a prioritisation scheme for riparian vegetation in the catchment and estuary • Quantification of the impact that proposed entrance training works will have on tidal inundation and the distribution of salinity throughout the estuary and its interaction with sea level rise • Impacts of instream sediment accumulation on flow and ecosystem health over time • Impact of climate change on catchment hydrology, diffuse pollutant transport, biodiversity, salinity distribution patterns, overtopping of levees • Undertake e-DNA research to characterise aquatic fauna abundance, diversity and presence of exotic species. • Develop prioritisation, indicators, stressors and thresholds for aquatic fauna • Model sediment inputs from significant sources across the catchment to better prioritise management actions • Distribution of seagrass and analysis of activities, stressors and impacts
