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, a CTR of < 1 detection of common native mammals per 100 trap-nights should be considered a critical lower threshold, signifying a state of faunal depletion and high risk of local extinctions.

Metric Definition:

Camera Trap Detection Rate indicating faunal depletion threshold

Benchmark Definition:

A camera trap detection rate below 1 detection per 100 trap-nights indicates a severely compromised ecosystem with high risk of local extinctions in tropical and subtropical rainforest grazing landscapes.

Justification:

A CTR below 1 detection per 100 trap-nights indicates a severely compromised ecosystem with high risk of local extinctions.
