Scoring Curve

This curve shows how a field measurement for this indicator would score across all available benchmark forms in this context.

Evidence & Context

Woody cover may fluctuate significantly between the sparse woodland (5-19% cover) and the open forest (20-50% cover) categories.

Metric Definition:

Range of canopy cover percentages defining sparse woodland and open forest categories in subalpine zones.

Benchmark Definition:

This benchmark defines the canopy cover range representing the transition from sparse woodland to open forest in alpine and subalpine zones.

Justification:

Reflects natural variability in canopy cover due to environmental constraints in subalpine zones.
