This data is part of the 2013 report Synthesis of seagrass mapping studies conducted by the Water Science Branch of the Department of Water. Surveys were initially conducted by the WA Department of Water. The objectives of the study were to map the distribution of the different seagrass species found in Princess Royal Harbour and Oyster Harbour and to compare the distributions with that observed in previous studies (1996 and 2003). This data was acquired by the ACEAS Seagrass Group as part of the 2013 Australia-wide risk assessment of Seagrass. Surveys were conducted again in January and March 2021 by the Department of Water and Environmental Regulation as Princess Royal Harbour Seagrass Survey.

Brief description

Repeat surveys of aquatic flora were conducted in Princess Royal Harbour in 1996, 2003, 2005 and 2006. This data is part of the 2013 report "Synthesis of seagrass mapping studies" conducted by the Water Science Branch of the Department of Water. Surveys were initially conducted by the WA Department of Water. The objectives of the study were to map the distribution of the different seagrass species found in Princess Royal Harbour and Oyster Harbour and to compare the distributions with that observed in previous studies (1996 and 2003). This data was acquired by the ACEAS Seagrass Group as part of the 2013 Australia-wide risk assessment of Seagrass. Surveys were conducted again in January and March 2021 by the Department of Water and Environmental Regulation as "Princess Royal Harbour Seagrass Survey". The datasets making up the 1996-2006 Princess Royal Harbour seagrass survey data are: WA_PrincessRoyal_seagrass_polygons - polygon dataset showing interpolated percentage cover of seagrass. This record provides access to the initial WA DoW surveys. See associated DWER records in Data WA catalogue for access to newer surveys at this site.
