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

Evidence & Context

A litter cover below 40-50% is considered critically low, as it significantly increases the risk of wind and water erosion, a key threatening process in this environment.

Metric Definition:

Critical lower threshold percentage of litter cover below which ecosystem function is impaired due to increased erosion risk.

Benchmark Definition:

Lower critical threshold for litter cover to prevent soil erosion and maintain ecosystem function in the Arid Inland Floodplains biome under production forestry.

Justification:

Supported by national ground cover monitoring programs and Queensland government guidelines indicating increased erosion risk below this range.

Notes

Below this threshold, soil is vulnerable to raindrop impact, wind erosion, and flood scouring, leading to degradation.
