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
A CTR of < 1.0 Detections per 100 trap-nights for the native mammal assemblage is proposed as the lower critical threshold.
Camera Trap Detection Rate (CTR) expressed as Detections per 100 trap-nights for native ground-dwelling mammal assemblage.
Lower critical threshold below which the ecosystem's health and integrity are significantly compromised.
This low rate reflects a loss of critical habitat features (e.g., perennial grass cover), leading to an impoverished faunal assemblage dominated by a few generalist species.
