What is a tree line in golf?

Definition

The boundary or edge where trees meet fairways, rough, or other course areas, creating both strategic challenges and visual definition for golf holes. Tree lines serve as natural hazards that can block shot paths, create recovery situations, and influence course management decisions. Well-designed tree lines provide strategic options while maintaining playability, offering risk-reward scenarios for aggressive players while providing safer routes for conservative approaches. Tree line management is an important aspect of course maintenance and design philosophy.
