<br /><strong>Updated with new data on 31 Aug 2023</strong><br />
<p>As part of recent changes to the Resource Management (Stock Exclusion) Regulations 2020 (the regulations), the following requirements in the regulations will no longer apply to the geographic area identified as the Upper Taieri Scroll Plain:<br>
• excluding non-intensively grazed beef cattle and deer from lakes and wide rivers on low slope land (regulations 14 and 15); and<br>
• excluding all stock from natural wetlands (regulations 16, 17 and 18).<br>
The Upper Taieri Scroll Plain is an area of regionally significant wetlands in Otago. The size and complexity of these wetlands mean they are unique and particularly challenging for excluding stock.<br>
The above exception has been provided on the basis that Otago Regional Council will implement suitable provisions in its regional plan for managing grazing within the wetlands, as soon as reasonably practical and no later than 1 July 2025.<br>
Other requirements to exclude stock and manage wetlands will continue to apply in respect of the wetlands. This includes existing direction in the National Policy Statement for Freshwater Management 2020 and National Environmental Standards for Freshwater 2020 (see wetlands implementation guidance <a href="https://environment.govt.nz/acts-and-regulations/freshwater-implementation-guidance/wetlands/">environment.govt.nz/acts-and-regulations/freshwate...</a>). </p>
<p>The map shows the area of land in the Upper Taieri Scroll Plain that relate to this exception in the Regulations.</p>

<p>The Stock Exclusion Low Slope Land 2022 layer identifies areas of "Low Slope Land" as defined in the Resource Management (Stock Exclusion) Regulations 2020. The layer shows land with a local slope of less than or equal to 5 degrees where beef cattle and deer are required to be excluded from waterways. Areas of lakes, ponds, settlements, urban parkland, transport infrastructure and estuarine open water, as defined in Land Cover Database 5, are excluded. Areas over 500m in altitude are also excluded. This layer replaces the Stock Exclusion Low Slope Land 2020 layer. Please refer to <a href="https://data.mfe.govt.nz/layer/114341">data.mfe.govt.nz/layer/114341</a> for areas that are not subject to these requirements.</p>

<p>The Stock Exclusion Low Slope Land 2020 layer identified areas of "low slope land" as defined in the Resource Management (Stock Exclusion) Regulations 2020 when the regulation was first gazetted in 2020. In December 2022 the dataset was superseded by the Stock Exclusion Low Slope Land 2022 layer.</p>
<p>The layer shows the land parcels, or part parcels, defined as low slope land. These areas have a mean slope is less than or equal to 10 degrees. Parcels with a parcel intent of "ROAD" are excluded. Areas of lakes, ponds, settlements and urban parkland, as defined in Land Cover Database 5, are also excluded. Areas of low-slope grassland and annual cropland within high-slope parcels are also included in the Stock Exclusion Low Slope Land extent.</p>

<p>The Stock Exclusion Medium Slope Land 2022 layer identifies areas with a slope of between 5 and 10 degrees below 500m in altitude where excluding stock from waterways is likely to be practical and advisable. This layer has been created using the same method used to create the Stock Exclusion Low Slope Land 2022 layer which represents "Low Slope Land" as defined in the Resource Management (Stock Exclusion) Regulations 2020. This layer is intended to be used in conjunction with the Stock Exclusion Low Slope Land 2022 layer to support planning for stock exclusion.</p>

<p>This data set provides an update of New Zealand’s depth to hydrogeological basement map. Depth to hydrogeological basement can be loosely defined as the ‘base of aquifers’; or more strictly as ‘the depth to where primary porosity and permeability of geological material is low enough such that flued volumes and flow rates can be considered negligible’. For more detail on the process and methods, see Westerhoff et al. (2019). New Zealand groundwater atlas: depth to hydrogeological basement.

<p></p>
<p><strong>This dataset contains predictions of the susceptibility to streambank erosion for every stream link in the RECv2.5 digital river network. Streambank erosion susceptibility is computed as a dimensionless index (range 0-100) for each stream link based on factors that may influence reach-scale bank erosion. These factors comprise stream power, the extent of riparian woody vegetation, valley confinement, channel sinuosity, and the erodibility of stream banks based on soil texture. The approach for determining streambank erosion susceptibility is described by Smith & Betts (2021) and based on the bank erosion model developed by Smith et al. (2019).</strong></p>

<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>

There are three components: Groundwater recharge: development of nationwide mean (daily and seasonal) groundwater recharge data sets through the combination of three pre-existing groundwater recharge models; Groundwater–surface water exchange: development of a national indicative groundwater discharge data set using an existing national groundwater flow model, as well as comparison with a pre-existing gaining/losing stream prediction data set; Groundwater flow: development of a national groundwater flow data set using an existing national groundwater flow model. For more detail on the process and methods, see Westerhoff et al. (2019). New Zealand groundwater atlas: Groundwater Fluxes. Lower Hutt (NZ): GNS Science. 60 p. Consultancy Report 2019/126.</p>

<p>New Zealand Hydrogeological unit map (HUM) separated into aquifers, aquitards, aquicludes and basement developed in a nationally-consistent manner. This dataset includes only outcropping hydrogeological units. This dataset was also joined to the hydrogeological system dataset (Moreau et al. 2019), to provide a single polygon for each unique combination of HUM and hydrogeological system. Summary statistics of surficially mapped products are provided for each polygon (groundwater use, flow, recharge, discharge to the surface; depth to hydrogeological basement; and number of drinking water wells serving >100 people).</p>

<p>This dataset shows land that would be covered by the option 1 of section 8.4 Immediate action to reduce nitrogen loss. </p>
<p>This web map has been developed by the Ministry for the Environment to support policy proposals in the Action for Healthy Waterways discussion document. The proposals are currently being consulted on. </p>
<p>It provides extra detail on Option 1 in section 8.4 of the discussion document (Immediate action to reduce nitrogen loss). The map indicates the pastoral catchments and sub-catchments specified as high-nitrate in Option 1, where regional rules are not already in place or proposed, and shows the land considered to be low-slope. </p>
<p>Low-slope is defined in this option as land parcels with an average slope of less than 5, 7 or 10 degrees. We are seeking feedback on the appropriate slope threshold to use. </p>
<p>The catchments are those with the highest 10% of nitrate levels in the MfE Environmental Reporting River Water Quality dataset found here. Catchments where the predominant sources of nitrate are non-pastoral in origin are excluded. </p>
<p>Under Option 1, a per-hectare cap, or threshold, for nitrogen losses will be set for each sub-catchment with similar soil type and rainfall. This threshold will be based on a ranking of nitrogen losses from farms within each sub-catchment, and could be set at the 90th percentile, or the 70th, or a point between. Feedback is sought on where this threshold should be set. </p>
<p>This is only one of the options being consulted on, The areas indicated are provisional and may not equate to areas included in regulation.</p>

<p>The map provides extra detail on Option 3 in section 8.4: Immediate action to reduce nitrogen loss, of the discussion document. The map indicates the high-nitrate catchments and sub-catchments that could be included under Option 3. These catchments have the highest 10% of nitrate levels in the MfE Environmental Reporting River Water Quality dataset which can be found <a href="https://data.mfe.govt.nz/table/99867-river-water-quality-state-20132017/">here</a>. The catchments are further restricted to regions that do not have rules already in place or proposed. Catchments where the predominant sources of nitrate are not pastoral or horticultural in origin have been excluded.</p>
<p>Under this option, farmers in these catchments would have to show, in the freshwater module in their farm plan, how they will rapidly reduce nutrient leaching. Progress against the plan would be monitored by independent auditors and the regional council could take enforcement action if required.</p>
<p>This is only one of the options being consulted on. The areas indicated are provisional and may not equate to areas included in a regulation.</p>
