Evidence & Context

The optimal range for TCC in temperate dry woodlands under ecologically focused production forestry is considered to be 20-50%.

Metric Definition:

Tree Canopy Cover (TCC) is defined for this study as the "percentage ground shaded by tree canopy"

Benchmark Definition:

Range most likely to promote overall ecosystem health, support characteristic biodiversity, and allow for sustainable production of forest products.

Justification:

Aligns with national definitions of 'woodland forest' (20-50% crown cover) and supports a balance between canopy functions and understorey health.
