Seagrass Habitat Mapping

Seagrass habitat mapping and monitoring has been conducted to understand the biophysical characteristics of seagrass habitats through space and time and has been studied in various regions, including Moreton Bay, Cockburn Sound, Lizard Island, Flinders Island, Tasmania, and Indonesia. For Moreton Bay, see the long-term monitoring section

Summary

Our seagrass research has been primarily developed in the Moreton Bay study areas (see seagrass long term monitoring. We developed and applied mapping, modelling and monitoring to understand the biophysical characteristics of seagrass through space and time since 1999.  

Various projects used the lessons learned in Moreton Bay to further develop it for other projects such in Cockburn Sound, Western Australia, Lizard Island, Green Island, Flinders Island in Tasmania and overseas Solomons and Fiji,. The knowledge gained for mapping seagrass properties  at large spatial extents regions to country scale is building on the experience with creating the habitat maps for the Allen Coral Atlas. The work resulted in ongoing activity in Indonesia with the Packard Foundation and form the basis to develop mapping approaches and seagrass knowledge hub at global scale.
