Hinchinbrook Island and Channel encompass the full spectrum of tropical coastal wetlands, from freshwater swamps, through mangroves and tidal flats, to seagrass meadows and fringing reefs. This complex of ecosystems supports a diversity of species from crabs to crocs, barramundi to birds, dolphins, and dugong. The mosaic of connected wetlands provides a great diversity of habitats and resources that support productive nurseries as well as critical adult habitat for many culturally and ecologically important species. Despite their high values, the way these wetlands are used by most species remains unclear. Ongoing research in the coastal wetlands of Hinchinbrook is uncovering more of the secrets of these rich and productive systems.
