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 11 benchmarks together — the OptimalRange form drives the primary score, while 10 guard(s) constrain the result.

Evidence & Context

The reference value of 22.1% bare ground represents an achievable benchmark for high ecological health in sustainably managed livestock grazing systems within Australia's temperate semi-arid woodlands.

Metric Definition:

Bare Ground (%)

Benchmark Definition:

This benchmark represents the percentage of bare ground that indicates high ecological health in sustainably managed livestock grazing systems within Australia's temperate semi-arid woodlands.

Justification:

This value is the 25th percentile derived from a national, multi-site analysis of TERN AusPlots field data, reflecting the condition of the top quartile of real-world managed sites.

Notes

This benchmark sits well within the optimal range for landscape function. The broader functional range for this indicator is defined by clear ecological thresholds: Lower Critical Threshold: Bare ground levels exceeding 50% represent a critical threshold where soils become highly vulnerable to significant wind and water erosion, leading to a loss of landscape function. Management should aim to maintain bare ground below 30% (>70% total ground cover) to effectively control water erosion, maximize rainfall infiltration, and support healthy, resilient pastures. The scientific literature provides no evidence of a detrimental upper threshold for ground cover; lower bare ground is consistently associated with improved ecosystem health.
