Scoring Curve

This curve shows how a field measurement for this indicator would score across all available benchmark forms in this context.

Evidence & Context

The proposed benchmark is the 25th percentile value for HTE cover, which is 0.075%.

Metric Definition:

Percentage cover of High Threat Exotic (HTE) species in temperate woodland reference sites.

Benchmark Definition:

This benchmark represents the percentage cover of High Threat Exotic species in temperate woodland areas under rehabilitation, with a target set at the 25th percentile value to encourage low invasive species presence.

Justification:

The 25th percentile represents a condition better than 75% of high-quality reference sites, setting an ambitious yet achievable target for best-practice management.

Notes

The ideal state is 0% HTE cover. The optimal operational range is 0% to 0.075%. An HTE cover exceeding the 75th percentile (~0.33%) indicates a significantly compromised system.
