Evidence & Context

The 30% reference value is the explicit management target from a best-practice regenerative grazing system ('Campview' station, QLD) operating within the target biome.

Metric Definition:

Tree Canopy Cover (TCC) within Australian Temperate Semi-Arid Shrublands & Open Woodlands under a Production Forestry land use context.

Benchmark Definition:

Tree Canopy Cover (TCC) is the percentage of ground covered by tree canopy in the target biome and land use, representing an optimal balance for ecosystem health in a water-limited environment.

Justification:

The 30% value is empirically grounded as the explicit management target of a documented best-practice regenerative grazing enterprise operating within the target biome, supported by ecological theory and national structural classifications.

Notes

Lower Critical Threshold: below 20% is critically low, representing a structural shift away from woodland and loss of key functions. Optimal Range: 25-40% balances habitat, carbon sequestration, soil health, and water availability. Upper Detrimental Threshold: above 50% leads to suppression of understorey biodiversity and reduced groundwater recharge.
