NESP TWQ Round 1 - Project 3.1 - Seagrass mapping synthesis - A resource for marine park and coastal management

Region map

Key to understanding the desired state of Queensland seagrasses is reliable data on seagrass distribution, abundance and species composition, and how this changes through time. Also valuable is the ability to reliably “drill” down from large-scale (World Heritage Area) to small-scale estuaries and meadows. TropWATER provides a composite map of seagrass for the GBRWHA available through eAtlas, GBRMPA and Pangaea. However this layer has not been updated since 2010 and is missing changes from important areas and extensive new data, and provides no meadow-specific information. This project will recompile existing GIS layers, update with 2010-2015 data, and provide meadow-specific information.
