Ground Cover - Tree Canopy
Benchmark Value
Scoring Curve
This curve shows how a field measurement for this indicator would score across all available benchmark forms in this context. The scoring engine uses 12 benchmarks together — the OptimalRange form drives the primary score, while 11 guard(s) constrain the result.
Evidence & Context
The optimal range for TCC is 70-95%. It is critical, however, that this range is interpreted with the major caveat that it applies only to a canopy that is structurally complex and dominated by a diverse suite of native tree species.
Tree Canopy Cover (TCC) as the percentage of ground area covered by the vertical projection of the outermost perimeter of tree crowns.
The optimal Tree Canopy Cover (TCC) range in Tropical and Subtropical Rainforests conservation areas is 70-95%, reflecting structurally complex canopies dominated by diverse native tree species.
This range is characteristic of 'best-on-offer' reference sites and high-quality, well-managed conservation areas.
