SoE2020: Extent and rate of change of freshwater wetland systems

More than 94% of the pre-European settlement extent of freshwater wetlands in Queensland remained in 2017. Changes in the extent of freshwater wetlands have been monitored in Queensland since 2001. The rate of freshwater wetland loss reduced to 0.05% during 2005–2009 and 0.02% in 2009–2013. Between 2013 and 2017 that rate has increased to 0.13% due to agricultural expansion and infrastructure development.Of the 3 freshwater wetland systems — lacustrine, palustrine, riverine — the greatest ongoing losses have occurred in riverine and palustrine systems in the Gulf and North East Coast Drainage (Great Barrier Reef) divisions.

截至2017年，澳大利亚昆士兰州的淡水湿地仍保留了其欧洲殖民前总面积的94%以上。自2001年起，昆士兰州已对淡水湿地的面积变化开展长期监测。2005年至2009年间，淡水湿地的年流失率降至0.05%；2009年至2013年间，该流失率进一步下降至0.02%。2013年至2017年间，受农业扩张与基础设施建设的影响，淡水湿地的流失率回升至0.13%。在湖泊型（lacustrine）、沼生型（palustrine）与河流型（riverine）三类淡水湿地系统中，海湾与东北沿海流域（大堡礁）分区内的河流型与沼生型湿地目前正面临最为严重的持续性流失。
