Definition

1. Adjective:
   • Closed-canopy: Describes a forest or stand of trees where the crowns (the branches and leaves at the top) of the trees are touching or overlapping, forming a continuous, dense layer that largely blocks sunlight from reaching the forest floor. This is a technical term used in forestry and ecology.
