Camera Trap Detection Rate
Benchmark Value
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
Therefore, the proposed Reference Value for Camera Trap Detection Rate in a best-practice livestock grazing system in Australia's tropical monsoonal savannas is 3.5 – 4.0 Detections per 100 trap-nights.
Camera Trap Detection Rate (CTR) expressed as Detections per 100 trap-nights for native ground-dwelling mammal assemblage.
The total detection rate for the native ground-dwelling mammal assemblage in a tropical savanna under best-practice, sustainable livestock grazing.
It is a synthesized value derived by establishing a reference baseline from protected areas (Einoder et al. 2018; mean weekly mammal detectability of 0.36 converted to ~5.1 detections/100 trap-nights) and applying a -30% adjustment to account for the documented impacts of moderate grazing on faunal assemblages in a long-term trial (Kutt et al. 2012).
