A jungle filled with floating islands and jungles, forming what can be viewed as kind of a canopy extension.
The ground and floating islands are hyperdiverse and well interconnected.
The islands are connected to each other and the ground by vines.
The way the islands got populated is fascinating. As the forest developed on the ground, birds brought seeds to the islands, which brought trees and vines, the vines crept down to the ground and let land animals climb up to the islands, only increasing species transfer.
