Canopy Definitions Shape Canopy Space Filling-Productivity Relationships: Evidence From Terrestrial Laser Scanning. [PDF]

Ecol Evol
The spatial arrangement of trees and their branches within the canopy is crucial for light interception, often resulting in a positive relationship between canopy space filling and stand productivity. To date, there is no universal definition of canopy space.
