Technical report on the prototype New Zealand river ecosystem health score

Publication date:  August 2020
Publication reference number:  CR 445

This report describes a prototype for a New Zealand River Ecosystem Health Scorecard, conceived as a simple, easily interpretable and holistic communication tool for the state of the biophysical condition of rivers and streams in New Zealand. It is based on the Freshwater Biophysical Ecosystem Health Framework and assesses the five core components of ecosystem health. The prototype was limited to available national scale data and information, which highlighted existing data gaps and deficiencies. As a proof of concept this prototype is relevant for implementing the ‘Assessing and reporting’ policies in the National Policy Statement for Freshwater Management 2020.
