Evidence & Context

Low severity disturbance is defined as less than 30% canopy cover loss.

Metric Definition:

Maximum canopy cover loss percentage indicating minor damage with likely recovery.

Benchmark Definition:

This benchmark indicates that canopy cover loss below 30% is considered low severity with minor damage and likely recovery.
