<p>For seasonal trends, sites needed to have at least six complete seasons between 2011 and 2020. New to this update: not all seasons had to be complete – the previous update only calculated trends over complete seasons.<br>
Seasonal trends between 2011 and 2020 for:<br>
- Particulate matter 10 (PM10) concentrations<br>
- Particulate matter 2.5 (PM2.5) concentrations<br>
- Nitrogen dioxide (NO2) concentrations<br>
- Sulphur dioxide (SO2) concentrations<br>
- Carbon monoxide (CO) concentrations<br>
- Ground-level ozone concentrations </p>
<p>Variables:<br>
pollutant: abbreviated pollutant name, chemical name, or chemical formula (e.g., PM10, Ozone, or CO)<br>
site: regional council or unitary authority unique name for site<br>
airshed: gazetted name of airshed<br>
lat: site latitude<br>
long: site longitude<br>
season: season of trend<br>
likelihood: trend direction (“improving, “worsening”, or “indeterminate” – for more information see Stats NZ indicator webpages).<br>
significant: TRUE if the trend is statistically significant, otherwise FALSE<br>
p: p-value to assess level of statistical significance<br>
slope: slope of the trend line (average units/year change)<br>
lower: lower limit of the 95% confidence interval of the slope<br>
upper: upper limit of the 95% confidence interval of the slope<br>
intercept: intercept of the trend line<br>
period_start: first year of the trend period<br>
period_end: last year of the trend period<br>
trend_type: type of trend (i.e., annual or seasonal)</p>

<br /><strong>Updated with new data on 11 Jan 2016</strong><br />
<p>"Freshwater plant and animal pests can have significant negative impacts on ecosystem health by reducing indigenous biodiversity through predation and competition, and destabilising aquatic habitats. Freshwater plant pests can cause economic losses through blocking water intakes for hydroelectricity generation, impeded drainage or irrigation. In addition, pests can affect the suitability for recreational activities.<br>
This dataset relates to the "Freshwater pests" measure on the Environmental Indicators, Te taiao Aotearoa website. "</p>
