On the swamp
As for real places that resemble Matope, it's a pretty alien place, but the Everglades are a good place to start, as Matope was inspired by watching several TV shows about the Everglades in a row. Just like Matope the Everglades have
Mangrove forests,
Cypress forests covered in kudzu,
marshes, and
sawgrass prairies.
"Coastline" is a bit misleading. It really looks more like
this than a typical coastline like you're probably envisioning. There are
sandy beaches but they're mostly sloping out of big salty marshes. And then open ocean, punctuated by a few standing mangrove patches.
