overstory

Uppermost tree layer

The overstory is the uppermost layer of foliage in a forest—the canopy formed by the crowns of the tallest trees.

It contrasts with the understory, the vegetation growing beneath.

The term appears in ecology and forestry: The overstory blocked most of the sunlight from reaching the forest floor.
