In May 2003, the Australian Government announced a Great Barrier Reef Coastal Wetlands Protection Program (GBRCWPP) to develop and implement measures for the long term conservation and management of priority wetlands in the Great Barrier Reef Catchment.
This will assist in achieving the goal of the Reef Water Quality Protection Plan, which aims to halt and reverse the decline in the quality of water entering the Reef.
The GBRCWPP responds to concerns about the potential impact on the Great Barrier Reef from the loss of wetlands along the Queensland coast. The area of wetlands in the Great Barrier Reef catchment has decreased by over 50 per cent since European settlement, including 80 per cent of the Melaleuca wetlands on the Herbert River Floodplain and over 50 per cent of freshwater wetlands in the Johnstone, Russell-Mulgrave and Morseby river floodplains (Furnas, 2003 Catchments and Corals- Terrestrial runoff to the Great Barrier Reef. AIMS/CRC Reef. ISBN 0 642 55041 7).
Wetland clearing and drainage allows increasing levels of sediment and nutrient to enter the Great Barrier Reef lagoon. Sediment smothers coral, while increased levels of phosphorous and nitrogen in runoff can promote the growth of algae that compete with coral. The combination of increased sediment and nutrients runoff restricts growth and reproduction of coral. Sediment and nutrient pollutants entering the reef lagoon have increased several fold since pre-European times and are associated with vegetation clearing and agriculture. The majority of sediments and nutrients enter the reef lagoon during and following flood events. Near-shore reefs bordering the Wet Tropics and Whitsundays are most affected by runoff and are considered to be at greatest risk of further damage (Reef Water Quality Protection Plan).
This interactive tool explains the vital role wetlands play in keeping our Great Barrier Reef great. It is designed to appeal to all ages and is especially useful for students.
Exploring our Wetlands takes you on a journey using interpretive material and interactive learning activities to explore what are wetlands, their values and importance in protecting the Great Barrier Reef. This tool also explores some of the main impacts on wetlands and how you can be involved in their protection. It also allows you to hear stories of what role wetlands play for different community groups.
Exploring our Wetlands provides information about wetlands, the environment, science and the conservation of the natural environment.
