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 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.
Camera Trap Detection Rate (CTR) expressed as Detections per 100 trap-nights for native ground-dwelling mammal assemblage.
Upper detrimental threshold above which the ecosystem may be in a state of compositional imbalance.
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.
