According to scientists from Brown University and the Smithsonian Environmental Research Center, mangrove forests are moving north along most of Florida's east coast and flourishing in regions where they used to die in winter cold snaps.
Lead researcher Kyle Cavanaugh says 28 years of satellite imagery clearly show the mangroves crowding out the salt marsh along the northeast Florida coast between St. Augustine and Titusville. It's probably climate change, he says, not a decrease in average temperatures, but in the number of freezing nights.
"In the mid to late 1980, Daytona Beach was experiencing these events one to two times a year", said Cavanaugh. "But by 2010, the events were only occurring every one to three years"
