Introducing the Freshwater Ecosystem Condition Index: A 0–100 eDNA Score for UK Rivers and Streams
6th May 2026
NatureMetrics has launched the Freshwater ECI, a 0–100 ecological condition score for UK rivers derived from a single litre of water using eDNA. Built on a decade of consistently collected, proprietary eDNA data and calibrated against UK Water Framework Directive status bands, the index offers a scalable, biologically grounded alternative to traditional freshwater monitoring methods.
