Evidence & Context

The optimal functional range of 20-40% tree canopy cover represents the "sweet spot" where the goals of ecological health, biodiversity conservation, and sustainable agricultural production are not only compatible but synergistic.

Metric Definition:

Tree canopy cover percentage range representing optimal ecological and production outcomes.

Benchmark Definition:

Optimal functional range of tree canopy cover for temperate grassy woodlands under sustainable grazing.

Justification:

This range balances open woodland structure, biodiversity support, and livestock productivity, and is supported by carbon farming methodologies and production research.
