What threatens seagrass? The … An evidence-based approach for setting desired state in a complex Great Barrier Reef seagrass ecosystem: A case study from Cleveland Bay Author links open overlay panel C.J. Wild and windy. The MMP assesses the health of key marine ecosystems (inshore coral reefs and intertidal seagrasses), and the condition of water quality in the inshore GBR lagoon. Overall the Great Barrier Reef’s inshore marine condition was poor in 2017–18, based on scores for coral, seagrass and water quality. Seagrass is also important for carbon sequestration. Seagrass Communities in the Shoalwater Bay Region, Queensland Spring (September) 1995 and Autumn (April) 1996 W JLee Long, LJMcKenzie and R G Coles Northern Fisheries Centre Queensland Department of Prir:nary Industries A REPORT TO THE GREAT BARRIER REEF MARINE PARK AUTHORITY ©Great Barrier Reef Marine Park Authority, Queensland Departmentof Primary Industries 1997 ISSN 1037 … A … Seagrass-Watch; Great Barrier Reef Water Quality Protection Plan – Marine Monitoring Program: intertidal and Subtidal seagrass; Seagrass data collection and management for Indigenous groups Collaborative Scientists: Dr Catherine Collier. In 1997, the Great Barrier Reef Ministerial Council established Clairview as a dugong sanctuary. Reef Water Quality Report Marine Results 2017–18. Seagrass indicators, distribution and thresholds of potential concern. The Great Barrier Reef (GBR) supports a high diversity of seagrass species across a broad range of habitat types. Seagrass is widely distributed throughout the Great Barrier Reef (the Reef), with a documented 35,000 square kilometres and a potential habitat area of 228,300 square kilometres. The meadow of deep-water seagrass in the Great Barrier Reef is estimated to store 27.4 million tonnes of carbon. Mangroves, which are actually terrestrial plants that grow above the surface of the sea but have their roots in it, are also considered part of the Great … Incorporating resilience into management frameworks is increasingly recognised as critical to halt the degradation of our coastal ecosystems, and resilient ecosystems are clearly identified as an important component of the Reef 2050 Plan. 2011, Bainbridge et al. Carter a M. Rasheed a L. McKenzie a J. Udy b R. Coles a J. Brodie c M. Waycott d K.R. These systems are also closely linked with adjacent coastal river catchments in a catchment-to-reef continuum. INTRODUCTION . Monitoring inshore seagrasses is part of the Great Barrier Reef (GBR) Marine Monitoring Program (MMP). Seagrasses are of significant ecological importance to the GBR as their high productivity rates support green turtles and dugongs, … An adult green turtle eats about two kilograms of seagrass a day while an adult dugong eats about 28 kilograms a day. 1996). Collier a A.B. The Great Barrier Reef Outlook Report 2009 (Outlook Report 2009) noted the overall area of seagrass meadows was considered relatively stable over the proceeding 20 year period. Mangroves grow behind the coral reefs so they can protect them. Looking out at the sea, the turquoise water is scattered with dark patches, which are mostly comprised of seagrass beds. they have photosynthetic leaves and roots and rhizomes to anchor in the sediment and to grow via rhizome … Managing seagrass resources in the GBRWHA requires adequate baseline information on where seagrass is (presence/absence), what species are present, and date of … The Great Barrier Reef's Seagrass Is an Amazing Carbon Sink. They store carbon, stabilize bottom sediments and adsorb nutrients from coastal waters, helping to maintain good water quality … “CMERC is the only coastal and marine research facility based in Central Queensland, and it has a … This dataset summarises 35 years of seagrass data collection (1984-2018) within the Great Barrier Reef World Heritage Area into one GIS shapefile containing seagrass survey data as seagrass presence and absence for 81,387 sites. Water quality in the Great Barrier Reef region: responses of mangrove, seagrass and macroalgal communities Experimental fertilisation of sea grasses … Principal Researcher (James Cook University, Cairns) Catherine is broadly interested in coastal marine ecology, with a particular emphasis on seagrass eco … Dec 18, 2018 Andre Erlich Getty Images. They inhabit both freshwater and brackish water, where seagrass beds can be found. Dugongs feed on the seagrass meadows and come to the surface when they breathe. Catchment runoff presents a major threat to water quality and ecosystem health within the Great Barrier Reef (GBR) (Grech et al. The discovery of a new species of seagrass within the Great Barrier Reef region as recently as 1979 is indicative of the present poor state of knowledge. 1. 2018). 2016) to measure potential functional connectivity on seagrasses in the central Great Barrier Reef World Heritage Area (GBRWHA), Australia. Seagrasses in the Great Barrier Reef region, particularly in coastal habitats, act as a buffer between catchment inputs and reef communities and are important habitat for fisheries and a food source for dugong and green turtle.
