Evidence & Context

For the WDR (Eucalyptus delegatensis forest over rainforest) community in Tasmania, the verbatim tree canopy cover benchmark is 30%.

Metric Definition:

Projected foliage cover of the uppermost stratum (tree canopy cover).

Benchmark Definition:

This benchmark defines the tree canopy cover for the WDR community in Tasmania, representing a mature forest state with 30% canopy cover.

Justification:

Defines the benchmark for a mature and apparently long-undisturbed state of E. delegatensis forest.
