LeRoy Rodgers spends plenty of time in the Florida Everglades — mainly in airboats. He works for the South Florida Water Management District.
On a recent day, he eases his boat alongside a tree island. He doesn't like some of the changes he's seen, so he pulls a pair of clippers from a bag and hops over the side.
Rodgers will need the clippers to cut a path through the Old World climbing fern that has almost swallowed the island.
"A white-tailed deer trying to make your way through this," he says. "You can see how difficult it would be."
