Form: OptimalRange

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 4 benchmarks together — the OptimalRange form drives the primary score, while 3 guard(s) constrain the result.

Evidence & Context

This derived value of 30-40% litter cover represents a state of high ecological function. It is substantial enough to provide the critical benefits of soil protection, moisture retention, and nutrient cycling. At the same time, it is well below the extremely high levels (>60-70%) that are associated with the suppression of grass diversity and the development of dangerous fuel loads.

Metric Definition:

Litter cover refers specifically to the percentage of the ground surface that is obscured by detached, non-living plant material when viewed from directly above.

Benchmark Definition:

This benchmark represents the optimal litter cover percentage in Australian Tropical Monsoonal Savannas under best-practice livestock grazing, balancing soil protection, moisture retention, nutrient cycling, biodiversity maintenance, and fire risk management.

Justification:

Derived from long-term ecological stability and health observed in the moderate stocking rate treatment at the Wambiana grazing trial, representing a balance between soil protection and fire risk.
