Evidence & Context

The value of 30% is selected as the most scientifically defensible benchmark for Tree Canopy Cover.

Metric Definition:

Tree Canopy Cover (TCC) as the percentage of ground covered by tree canopy in Temperate Grassy Woodlands.

Benchmark Definition:

This benchmark represents a scientifically defensible target for tree canopy cover in Temperate Grassy Woodlands to maintain ecosystem health and biodiversity.

Justification:

This value represents the upper boundary of the healthy canopy cover range and aligns with ecological thinning targets to prevent degradation.
