Evidence & Context

The analysis further defines a functional range for this indicator: an optimal range of 70-90%.

Metric Definition:

Percentage of ground covered by litter layer in tropical and subtropical rainforests.

Benchmark Definition:

This benchmark defines the optimal range of litter cover in tropical and subtropical rainforests that supports healthy ecosystem function, with thresholds indicating degradation and risk.

Justification:

Derived from ecological studies and the NSW BioNet dataset indicating critical thresholds and optimal functional range.
