Evidence & Context

Moderate severity disturbance is defined as 30–50% canopy cover loss.

Metric Definition:

Range of canopy cover loss percentage indicating significant structural change.

Benchmark Definition:

This benchmark indicates that canopy cover loss between 30% and 50% represents moderate severity with significant structural change.
