This curve shows how a field measurement for this indicator would score across all available benchmark forms in this context. The scoring engine uses 19 benchmarks together — the OptimalRange form drives the primary score, while 18 guard(s) constrain the result.
Contributing Benchmarks
Evidence & Context
A TCC greater than 40% constitutes an upper detrimental threshold.
Upper detrimental threshold for Tree Canopy Cover (TCC) above which woody encroachment and loss of fire-maintaining processes occur
The upper detrimental threshold beyond which pasture is suppressed and fire processes are disrupted, risking a shift to closed-canopy woodland.
Exceeding 40% TCC breaks the grassy fuel continuity, preventing fire spread and triggering woody encroachment.
