Satellite imagery reveals a severe die-off of mangroves along Australia’s northern coast. More than 7,000 hectares (27 miles) of mangroves have dried up, research indicates. The tree deaths come amid high temperatures that have also been linked to massive coral bleaching and kelp forest deaths in the region.
Natural-color images were acquired on July 15, 2014, and July 20, 2016, by the Operational Land Imager (OLI) on Landsat 8. They capture the extent of mangrove die-offs on a strip of beach along the Gulf of Carpentaria.
Notable tree loss occurred between November and December 2015, said Norman Duke, leader of the Mangrove Research Hub at Australia’s James Cook University. Between 5 and 25 percent of trees have died along more than 1000 kilometers (620 miles) of shoreline and fringing inlets.
