Evidence & Context

"no areas with tree mortality higher than 5%."

Metric Definition:

Percentage of standing timber mortality in a management unit caused by invasive agents.

Benchmark Definition:

This benchmark indicates the maximum acceptable tree mortality caused by invasive agents in softwood plantations to maintain forest productivity and sustainability.

Justification:

Threshold where the impact of invasive pathogens or arthropods causes significant ecological harm.
