Ground Cover - Tree Canopy

AUS-TDG-FOR-TCC General Moderate confidence

Benchmark Value

60 %
Thresholds: Lower: —, Upper: 60
Direction: Lower is desirable ↓
Form: UpperThreshold

Scoring Curve

This curve shows how a field measurement for this indicator would score across all available benchmark forms in this context.

Evidence & Context

Therefore, a TCC exceeding approximately 50−60% is likely to be detrimental to the integrity of these grassy woodland ecosystems.

Metric Definition:

Tree Canopy Cover (TCC) upper detrimental threshold above which ecosystem integrity is harmed.

Benchmark Definition:

An upper detrimental threshold of 60% Tree Canopy Cover (TCC) above which shading suppresses native understorey and alters ecosystem structure in temperate dry woodlands.

Justification:

Based on ecological evidence that TCC above 50−60% shades out the species-rich understorey and changes ecosystem from grassy woodland to denser forest, reducing biodiversity.
