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 16 benchmarks together — the OptimalRange form drives the primary score, while 15 guard(s) constrain the result.

Evidence & Context
Lower Critical Threshold: < 0.5 m²/ha. Below this, the landscape loses self-sustaining woodland characteristics and essential ecosystem services (e.g., connectivity, resilience), risking a regime shift to a simplified treeless state.
Basal Area at which ecosystem function collapses and woodland characteristics are lost.
This benchmark defines the critical basal area threshold below which temperate dry woodlands and native grasslands lose self-sustaining woodland characteristics and essential ecosystem services.
Based on ecological collapse and loss of self-sustaining woodland characteristics as documented in the landscape.
