<br /><strong>Updated with new data on 03 Nov 2020</strong><br />
<p>This layer applies the sediment attributes’ classification, per Appendix 2C of the <a href="https://www.mfe.govt.nz/sites/default/files/media/Fresh%20water/national-policy-statement-for-freshwater-management-2020.pdf">NPS-FM 2020</a>, to the digital <a href="https://niwa.co.nz/freshwater-and-estuaries/management-tools/river-environment-classification-0">River Environment Classification (REC)</a> v2.4 network.</p>
<p></p>
<p>This layer is meant to support stakeholders in their understanding and implementation of the suspended and deposited sediment attributes, but it does not form part of the regulation; <strong>it is not incorporated by reference</strong>.</p>

<br /><strong>Updated with new data on 03 Jun 2020</strong><br />
<p>This dataset reports modelled mean annual suspended sediment load reduction required to meet suspended sediment attribute bottom lines in the NPS-FM 2020. Results are reported for the REC 2 river reach scale as well as at the “catchment pourpoint average” scale. The dataset includes masks for the DoC estate as well as glacial mountain source of flow.</p>
<p></p>
<p>During policy development, the Ministry for the Environment tested suspended sediment load reductions required to meet various potential attribute bottom lines. The information from February 2020 reflects the bottom lines in the NPS-FM 2020. For further information on this specific dataset, see “Hicks and Shankar 2020. Contract 23184 Task: Sediment load reductions to meet visual clarity bottom lines”. This report is available on the Ministry for the Environment’s <a href="https://www.mfe.govt.nz/publications/fresh-water/further-analyses-of-fine-sediment-attributes-support-development-of-nps">publications website</a> where it is listed as Technical Report 6.</p>
<p></p>
<p>For further information on the modelling, see Hicks et al. (2019) Sediment load reductions to meet suspended and deposited sediment thresholds. NIWA Client Report No. 2019100CH. Prepared for the Ministry for the Environment.

<p>This dataset reports erosion modelling results regarding annual mean sediment load reductions required to meet proposed suspended sediment attribute bottom lines. For more detail on the modelling process and methods, see Neverman et al. (2019). Impact testing of a proposed suspended sediment attribute: identifying erosion and sediment control mitigations to meet proposed sediment attribute bottom lines and the costs and benefits of those mitigations. Maanaki Whenua Landcare Research Client Report. Prepared for the Ministry for the Environment. </p>
<p>Results of modelled mitigations are reported at catchment scale and at the REC2 river reach scale. The modelled on-farm mitigations (per economic optimisation as reported in Neverman et al. (2019) are also mapped.</p>
