"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.
This dataset relates to the ""Freshwater pests"" measure on the Environmental Indicators, Te taiao Aotearoa website. "

New Zealand’s four million km2 marine environment is diverse, with a range of coastal habitats and offshore seabed environments. There are also many marine species unique to New Zealand. Marine protected areas conserve or manage some of these unique habitats and species, while a range of other tools also provide marine protection. We report on the area covered by these tools as an indirect measure to understand the state of the marine environment.
Marine reserves lie within our territorial sea (12 nautical mile limit) and offer the highest level of marine protection in New Zealand waters. No marine habitat or life form, such as seaweed or fish, may be removed from, or disturbed in, these places.

"The pressure from animal and plant pests is one of the biggest threats to biodiversity in the land environment. Pest predators (such as stoats and possums) eat eggs, birds, lizards, insects, and snails. Other animal pests (such as deer and goats) damage and kill trees and other plants and can compete with indigenous animals for the plants’ fruit and seed. Pest plants can out-grow the local vegetation. All these activities can dramatically change both our indigenous and agricultural environments.

This data set relates to the "Land pests" measure on the Environmental Indicators, Te taiao Aotearoa website."

Adapted by Ministry for the Environment and Statistics New Zealand to provide for environmental reporting transparency

Dataset used to develop the "Land fragmentation" indicator [available at www.stats.govt.nz/indicators/land-fragmentation]

This indicator measures changes in total highly productive land (HPL) area and the distribution of this land area across different land parcel size classes, since 2002, with a particular interest in the fragmentation or subdivision of these land parcels. We define HPL by land use capability (LUC), and includes classes 1, 2, and 3 (land highly suitable for growing a range of crops). We assess this fragmentation against two potential impacts: land that cannot be used or is restricted from use as farmland because of its new residential or urban land use (‘land restricted from use as farmland’) and that which may still be able to be used for growing/production (‘land potentially available for use as farmland’).

More information on this dataset and how it relates to our environmental reporting indicators and topics can be found in the attached data quality pdf. The technical report for this dataset is available at environment.govt.nz/publications/land-fragmentatio...

"The ocean waters surrounding New Zealand vary in temperature from north to south. They interact with heat and moisture in the atmosphere and affect our weather. Long-term changes and short-term variability in sea-surface temperatures can affect marine processes, habitats, and species. Some species may find it hard to survive in changing environmental conditions.

This layer shows annual sea-surface temperature difference from normal for 2010 as part of the data series for years 1993 to 2013. "Normal" is defined as the average sea-surface temperature for 1993–2013.

NIWA’s sea-surface temperature archive is derived from the Advanced Very High Resolution Radiometer (AVHRR) satellite data it receives from the National Oceanic and Atmospheric Administration. The archive provides high spatial (approximately 1km) and high temporal (approximately 6-hourly in cloud-free locations) resolution estimates of sea-surface temperatures over the New Zealand region, dating from January 1993. Uddstrom and Oien (1999) and Uddstrom (2003) describe the methods used to derive and validate the data.

This dataset relates to the "Annual average sea-surface temperature" measure on the Environmental Indicators, Te taiao Aotearoa website.

PM2.5 are particles 2.5 micrometres or less in diameter. PM2.5 is emitted from the combustion of fuels, such as wood and coal (eg from home heating and industry), and petrol and diesel (eg from vehicles). Natural sources have less influence on PM2.5 concentrations than PM10 concentrations. This means PM2.5 comes mainly from human activities. Nationally, burning wood or coal for home heating is the main source of PM2.5.

PM2.5 is a component of PM10 and is associated with similar health effects, ranging from respiratory irritation to some forms of cancer. However, the smaller PM2.5 particles are more closely associated with severe health problems.

Column headings:
- No_exceed - Number of exceedances
- Disp_graph - Displayed on graph (1= yes, 0 = no)

Phytoplankton are primary producers and form the basis of the oceans’ food chains. They contain the pigment chlorophyll-a (chl-a), which they use to create their own food through photosynthesis. We study concentrations of chl-a in phytoplankton to assess primary productivity in our oceans. Changes in productivity are likely to affect food chains and ultimately affect marine biodiversity, including the species we rely on for economic, cultural, or recreational purposes.

New Zealand has a diverse range of marine mammal species. Marine mammals are indicator species for the state of our marine environment. They are apex species (near the top of the food chain) and can thrive only if their ecosystems are healthy. A decreasing population can indicate that the ecosystem is degrading.
