Scoring Curve

This curve shows how a field measurement for this indicator would score across all available benchmark forms in this context. The scoring engine uses 12 benchmarks together — the OptimalRange form drives the primary score, while 11 guard(s) constrain the result.

Evidence & Context

Lower Critical Threshold: <10%. Below this level of canopy cover, the ecosystem ceases to function as a woodland.

Metric Definition:

Lower Critical Threshold for Tree Canopy Cover below which ecosystem function is impaired

Benchmark Definition:

The critical lower threshold of tree canopy cover below which woodland functions are lost and the ecosystem shifts to grassland or shrubland.

Justification:

Represents a state-change from woodland to grassland/shrubland. Characterized by loss of woodland-dependent functions, habitat structure, and landscape connectivity.
