This dataset summarises 30 years of seagrass data collection (1984-2014) within the Great Barrier Reef World Heritage Area. The Site data describes seagrass at 66,210 sites; while the Meadow data describes seagrass at 1,169 individual or composite meadows. The data includes information on species, meadow type and age and reliability of the data. The dataset is available as a shapefiles, GIS layer packages, and/or a CSV file. Data represented in this dataset has been collected by the TropWATER Seagrass Group and CSIRO in a GIS database.
This dataset is dominated by 822,000 'absent' compared to 37,666 'present' records.

Seagrass taxonomy has changed through time, with species such as Halophila ovata no longer recognised and some doubts expressed about other species whose morphology is relatively plastic. Field surveys have at times grouped species that are difficult to distinguish outside a laboratory. To address these issues we have amalgamated some species into complexes: Halophila ovata, Halophila minor, Halophila colesi/australis and Halophila ovalis are included as Halophila. ovalis. Halodule pinifolia is grouped with Halodule. uninervis. Data collected in winter may underestimate the extent of ephemeral species such as Halophila
decipiens and Halophila tricostata. This is important if this composite is used to compare annual changes. Zostera muelleri subsp. capricorni has been abbreviated to Zostera capricorni throughout.
