Camera Trap Detection Rate

AUS-TMS-LVG-CTR General Moderate confidence

Benchmark Value

4 Detections per 100 trap-nights
Thresholds: Lower: —, Upper: 4
Direction: Higher is desirable ↑
Form: UpperThreshold

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

A rate > 4.0 is not necessarily better and may indicate a detrimental state of compositional imbalance if driven by hyper-abundant generalist or invasive species rather than high native species richness.

Metric Definition:

Camera Trap Detection Rate (CTR) expressed as Detections per 100 trap-nights for native ground-dwelling mammal assemblage.

Benchmark Definition:

Upper detrimental threshold above which the ecosystem may be in a state of compositional imbalance.

Justification:

An anomalously high CTR could be driven by irruptions of one or two dominant native species or any invasive species, indicating a detrimental state of competitive exclusion or invasion.
