Marine results

Marine results cover water quality, seagrass and coral. The overall marine condition in 2009-2010 was moderate and has remained moderate since 2005-2006. There was some variability between regions, with the Burdekin and Burnett Mary in poor condition overall. Water quality and the condition of seagrass meadows and coral reefs also varied regionally.

Marine results are provided overall for the Great Barrier Reef and for each of the six regions.

There are significant time lags between altering land management practices and seeing results in the marine system. Reef Plan monitors outputs and outcomes at the farm, catchment and marine levels, and focuses on the long-term health of the reef.

The reef was affected by extreme events in 2009-2010. Significant rainfall led to comparatively high levels of fresh water entering the reef. Exposure to large volumes of low salinity flood waters for an extended period contributed to localised coral bleaching on shallow, inshore reefs. Tropical Cyclone Ului passed through the Mackay Whitsunday region in early 2010 causing damage to parts of the reef.
