Report Card 2016—Catchment loads

Modelling of pollutant load reductions is based on reported improvements in management practice systems. Results are an estimate of the annual average reduction in anthropogenic pollutant loads at the end of catchments between 2009 and 2016.

Scoring

A standardised scoring system was developed for each key indicator in the report card. The scoring system is used to assess and communicate progress towards the targets using the following categories.

Results—colour coding
A - Very goodB - GoodC - Moderate
D - PoorE - Very poorND - No data / NA - Not applicable in region

Indicator confidence is based on expert opinion and direct measures of error.

Further details on the scoring system (PDF, 527K) and qualitative confidence rankings for each indicator are outlines in the supporting technical information.
