Groundwater is the water stored beneath Earth’s surface in aquifers (layers of water-bearing rock or sand). It is used for human and stock drinking water, irrigation, and industry, and also has a role in sustaining some rivers, lakes, and wetlands, especially during low-flow periods. The health of surface-water ecosystems also depends on groundwater.

aquifer_ty = aquifer type
cubicm = estimated groundwater volume in cubic metres (m3)

Benzene is a volatile organic compound. Motor vehicle use and home heating are the main sources of airborne benzene emissions. Natural sources include volcanoes and forest fires. Benzene can affect the nervous system and is associated with some forms of cancer.

Benzene is emitted by human-made (motor vehicles, burning wood or coal for home heating, and some industrial activities) and natural (volcanoes and forest fires) sources.

Benzene is a volatile organic compound (VOC) that is common in the air. Motor vehicles are benzene’s primary emission source (Guerreiro, Foltescu, & de Leeuw, 2014; Weisel, 2010) although burning wood or coal for home heating, volcanoes, and forest fires also emit benzene.
Benzene is a human carcinogen (World Health Organization Regional Office for Europe Copenhagen, 2000) that has been shown to cause leukaemia (Smith, 2010), and is associated with developmental, immune, neurological, reproductive, and respiratory problems (Bahadar, Mostafalou, & Abdollahi, 2014). Acute exposure can affect the liver and respiration (Bahadar et al, 2014).

The status of our bird communities is an important indicator of the condition of our ecosystems. Many indigenous birds play key ecological roles, including dispersing seeds and pollinating flowers. In some situations, exotic (not indigenous to New Zealand) bird species can partially fulfil these roles. Measuring the composition of bird communities across public conservation land allows us to monitor how those communities are changing over time.

This dataset relates to the "Bird species on public conservation land" measure on the Environmental Indicators, Te taiao Aotearoa website.

The status of our bird communities is an important indicator of the condition of our ecosystems. Many indigenous birds play key ecological roles, including dispersing seeds and pollinating flowers. In some situations, exotic bird species (not indigenous to New Zealand) can partially fulfil these roles. A reduction in the distribution and/or decline in numbers for common and widespread species can equate to large losses of individuals and ecosystem integrity. By measuring the composition of bird communities across public conservation land (forest and non-forest sites) we can monitor how they change over time.

This measure reports on the estimated abundance of seven common bird species on public conservation land, 2013–2016.Common species are species having occupancy over half of public conservation land.

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

Dataset used to develop the "Bird species richness on public conservation land" indicator [available at www.stats.govt.nz/indicators/bird-species-richness...]

This dataset reports on bird species richness (the number of bird species observed) for indigenous and exotic widespread bird species on public conservation land from 2013 to 2019. We report this metric for both woody and non-woody areas.

Black carbon is a particle, often in the PM2.5 or ultra-fine size range, which is emitted from combustion sources and is commonly known as soot. In New Zealand most black carbon is emitted from vehicles (especially diesel vehicles), burning wood and coal for home heating, and outdoor burning. Both long and short-term exposure to black carbon is linked to serious health effects, such as respiratory and cardiovascular disease, cancer, and premature death (World Health Organization (WHO), 2013).
Black carbon warms the climate globally and regionally because it is efficient at absorbing energy from sunlight. Black carbon also increases ice and snow melt when deposited on these surfaces, darkening them and lowering albedo (proportion of light that is reflected) so they absorb more solar energy (Ramanathan & Carmichael, 2008).

The Hector’s and Māui’s dolphins are subspecies of the small dolphin Cephalorhynchus hectori. They are endemic to New Zealand (not found anywhere else). The Hector’s dolphin is classified as nationally endangered, while the Māui’s dolphin is nationally critical. Reporting incidental dolphin deaths from fishing helps us understand the pressures our protected marine species face from fishing.
This dataset relates to the "Bycatch of protected species: Hector’s and Māui’s dolphin" measure on the Environmental Indicators, Te taiao Aotearoa website.
