Camera Trap Detection Rate

AUS-AMR-LVG-CTR General Moderate confidence

Benchmark Value

1 Detections per 100 trap-nights
Thresholds: Lower: —, Upper: 1
Direction: Lower is desirable ↓
Form: MaximumOnly

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 9 benchmarks together — the OptimalRange form drives the primary score, while 8 guard(s) constrain the result.

Evidence & Context

Quantitatively, a CTR that is consistently below 1 detection per 100 trap-nights for multiple native guilds across multiple seasons would be a strong signal that the system has crossed this critical threshold and is in a severely degraded state.

Metric Definition:

Camera Trap Detection Rate indicating functional ecological collapse when consistently below this value.

Benchmark Definition:

Maximum Camera Trap Detection Rate below which the system is considered functionally collapsed in the Arid Mountain Ranges & Uplands biome under Livestock Grazing & Pasture land use.

Justification:

A CTR consistently below 1 detection per 100 trap-nights signals a critical state of functional collapse characterized by local extinction of sensitive species and dominance by invasive or hyper-resilient native species.
