Evidence & Context

"At least 70% of the ground in areas where regeneration is required should be mechanically exposed or an ashbed."

Metric Definition:

Proportion of ground mechanically exposed or ashbed

Benchmark Definition:

This benchmark defines the minimum proportion of ground that should be mechanically exposed or ashbed in alpine and subalpine production forestry areas to support natural regeneration by overcoming grass competition.

Justification:

Required to overcome grass competition
