Evidence & Context

Upper Detrimental Threshold: >30–40%. Canopy cover exceeding this range is indicative of woody thickening.

Metric Definition:

Upper Detrimental Threshold for Tree Canopy Cover above which ecosystem health is harmed

Benchmark Definition:

The critical upper threshold of tree canopy cover above which woody thickening causes ecological harm and necessitates management interventions.

Justification:

Represents a state of woody encroachment/thickening. Characterized by suppression of understorey biodiversity, loss of habitat for open-country fauna, and displacement of adjacent grassland ecosystems.
