What is the name of the rainforest canopy layer formed by the tallest Amazon trees?

The emergent layer is the rainforest canopy layer formed by the tallest Amazon trees rising above the continuous main canopy.

Emergent trees can receive intense sunlight and are exposed to stronger winds, higher temperatures, and greater drying than plants below them. Their crowns may stand well above the general canopy, creating isolated habitats in the uppermost part of the forest.

The layer is home to birds, insects, bats, and climbing animals that can move between high branches. Harpy eagles, for example, hunt in the upper forest and use large trees for nesting. Many emergent trees also produce flowers or fruits that attract animals from across the surrounding canopy.

The emergent layer is distinct from the main canopy, which forms a more continuous leafy roof. Beneath it are the understory, shrub and herb layers, and forest floor. Rainforest layers overlap, but the emergent layer specifically means the highest tree crowns.
