Benchmark Value

100 Detections per 100 trap-nights
Direction: Higher 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 2 benchmarks together — the MinimumOnly form drives the primary score, while 1 guard(s) constrain the result.

Evidence & Context

A total detection rate exceeding 100 detections/100 trap-nights, if dominated by a few hyper-abundant species (e.g., invasive feral pigs, or native generalists benefiting from simplified habitats), suggests a loss of ecosystem complexity and function.

Metric Definition:

Camera Trap Detection Rate (CTR) of ground fauna

Benchmark Definition:

This benchmark represents the upper detrimental threshold where high detection rates indicate ecological imbalance and loss of ecosystem complexity.

Justification:

Supported by evidence that intense grazing can reduce reptile diversity despite increasing the abundance of a few generalist species.

Notes

The threshold is defined by low evenness and dominance by invasive or generalist species, rather than a simple numerical cap. AssessmentContext defaulted to 'Not Stated' because the source document did not state one.
