April 30, 2018 (Source: FIU) - Mangroves running for their lives may have just hit the end of the road. The problem is so clear, it might be the first real sign Earth has entered a new geological era. Using a combination of aerial photographs from the 1930s, modern satellite imagery and ground sediment samples, FIU Sea Level Solutions Center researchers Randall W. Parkinson and John F. Meeder tracked the mangroves’ westward retreat from the coastal Everglades. Now, their backs are to the wall – literally. Having reached the L-31E levee in southeast Miami-Dade County, there’s nowhere left for mangroves in that part of the Everglades to flee. "You can see migration westward has stopped right where that levee is," Parkinson said. "In many cases there no space for them to migrate into — there’s development or some feature that blocks their migration. They’re done. That’s it."
