Benchmark Value

5 Detections per 100 trap-nights

Direction: Higher is desirable ↑

Form: MinimumOnly

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 2 benchmarks together — the MinimumOnly form drives the primary score, while 1 guard(s) constrain the result.

Evidence & Context

This threshold is reached when the native fauna detection rate falls below approximately 5 detections/100 trap-nights

Metric Definition:

Camera Trap Detection Rate (CTR) of native ground fauna

Benchmark Definition:

This benchmark represents the lower critical threshold below which the native fauna detection rate indicates significant ecological compromise.

Justification:

Reflects the conditions observed on Melville Island, where high cat abundance is linked to severe declines in native mammal richness and abundance.

Notes

A state of significant ecological compromise is indicated by this value and/or when invasive predators like feral cats constitute >10% of total detections. AssessmentContext defaulted to 'Not Stated' because the source document did not state one.
