  • Freshwater pests: Primrose willow

    Ministry for the Environment
    "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,...

  • Stream bed sedimentation - observed cover at fish monitoring sites

    Ministry for the Environment
    Fine sediment is the collective term for inorganic particles smaller than 2mm that are deposited on the beds of rivers and streams. Urban development, agriculture, and plantation forestry around waterways can increase the amount of sediment entering river systems. Sediment can clog the spaces between pebbles used by aquatic insects and fish, and degrade...

  • Estimated annual seabird captures in trawl and longline fisheries by fishery...

    Ministry for the Environment
    Along with sea lions, fur seals, and dolphins, seabirds are the protected species most directly affected by fisheries in New Zealand waters. Estimating seabird deaths from bycatch is one way of assessing the pressure some seabird species face from current fishing practices. This dataset relates to the "Bycatch of protected species: seabirds" measure on...

  • Marine economy: building consents (2007–2013)

    Ministry for the Environment
    The marine economy shows the contribution of marine-based economic activities to the New Zealand economy. Measuring the marine economy shows how New Zealand’s marine environment is used to generate economic activity and how this changes over time. However, these activities can also be a source of pressure on New Zealand’s marine environment. Building...

  • River Environment Classification Taranaki (2010) (DEPRECATED)

    Ministry for the Environment
    The New Zealand River Environment Classification (REC) organises information about the physical characteristics of New Zealand's rivers. Individual river sections are mapped according to physical factors such as climate, source of flow for the river water, topography, and geology, and catchment land cover eg, forest, pasture or urban. Sections of river...

  • High-class land for food production - Lifestyle blocks on high-class land,...

    Ministry for the Environment
    High-class land is the most productive land for growing food. It supports most crops across New Zealand. Expanding lifestyle blocks and urban areas reduces the availability of high-class land for commercial crop growing, and this land is unlikely to be returned to primary production. This affects our commercial food-production capacity. Column headings:...

  • Spring rainfall trends, 1960–2016

    Ministry for the Environment
    Spring rainfall trends for 30 representative sites from 1960–2016. Rain is vital for life – it supplies the water we need to drink and to grow our food, keeps our ecosystems healthy, and supplies our electricity. New Zealand’s mountainous terrain and location in the roaring forties mean rainfall varies across the country. Changes in rainfall amount or...

  • Nitrous oxide concentrations at Baring Head (1996–2013)

    Ministry for the Environment
    Greenhouse gases (GHGS) in the atmosphere absorb heat radiating from Earth, warming the atmosphere. Emissions from human activities increase the concentrations of these gases. Increases in these gases increase ocean acidity and are extremely likely to contribute to increased global temperatures, sea levels, and glacier melt. Monitoring GHG concentrations...

  • Primary productivity - chlorophyll-a anomalies (1997–2014)

    Ministry for the Environment
    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...

  • Seasonality of PM2.5 exceedances

    Ministry for the Environment
    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,...

    Ministry for the Environment
    Urban water quality indicators include heavy metals, nutrients, and E.coli. The concentrations of these indicators are compared to the proportion of urban land cover in catchments. Zinc and copper are heavy metals that can accumulate in sediments, shellfish, and other aquatic organisms. Metals can reach toxic levels in organisms making them unsafe to eat...
