eDNA Biodiversity Detection
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 6 benchmarks together — the OptimalRange form drives the primary score, while 5 guard(s) constrain the result.
Contributing Benchmarks
Evidence & Context
Lower Critical Threshold: A SIGNAL2 score <4.0 is the lower critical threshold, indicating 'Severely Impaired' ecosystem health and a failure of management to meet minimum environmental standards.
SIGNAL2 score representing the lower critical threshold for ecological health in streams
This benchmark defines the minimum SIGNAL2 score below which stream ecosystems in production forestry are considered severely impaired, indicating failure to meet environmental standards.
A score below 4.0 indicates severe pollution and ecosystem impairment, representing a failure of BMPs to protect water quality and biodiversity.
