<p>"Particulate matter 10 micrometres or less in diameter (PM10) in the air comprises solid particles and liquid droplets from both natural and human-made sources. PM10 can be emitted from the combustion of fuels, such as wood and coal (eg from home heating and industry), and petrol and diesel (from vehicles). Natural PM10 includes sea salt, dust, pollen, smoke (from bush fires), and volcanic ash. Nationally, burning wood or coal for home heating is the main human-made source of PM10. PM10 is of particular concern because it is found in high concentrations in some areas and can damage health. It is associated with effects ranging from respiratory irritation to some forms of cancer.</p>
<p>This dataset shows annual average PM10 concentrations for years 2006 to 2013. Field names are PM10_.<br>
This dataset also shows describes whether the PM10 trend, ie, whether concentrations have shown statisticsally significantly increases, decreases, or an indeterminate trend.</p>
<p>Data is broken down by monitoring site.</p>

Stock Exclusion Upper Taieri Scroll Plain, Otagotag:data.mfe.govt.nz,2023-08:layers:1143412023-08-21T20:54:00.280973+00:002023-08-31T21:31:43.445012+00:00

<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>
