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:
area_kha = area of land measured in kilohectares (ie multiply by 1000 to get hectares)

Eight indigenous tree species, spanning a range of ecological niches, were surveyed twice (between 2002 and 2014) as part of a vegetation monitoring programme. The data from these surveys can be used to assess changes in tree populations. Monitoring the status and trends of these widespread tree species helps us detect large-scale, long-term changes and problems for our forest ecosystems.

This dataset relates to the "Status of widespread indigenous trees" 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 (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 data measures the numbers of farmed livestock (dairy and beef cattle, deer, and sheep) over time across New Zealand.

Livestock farming is a widespread land use in New Zealand and is a large contributor to our economy. High livestock numbers and the distribution of livestock across land environments can affect indigenous biodiversity and soil health (eg through erosion, habitat loss, compaction, and nutrient concentration). Water quality can also be adversely affected, as nutrients, sediment, and bacteria from urine and faeces can leach or run off the land into rivers, lakes, and groundwaters. This can affect the health of the aquatic ecosystem, as well as recreation and cultural values associated with rivers and lakes.

New Zealand has been divided into 500 land environments. These have been defined by their unique climate, topography, and soils. The extent to which indigenous vegetation is represented in these land environments, and how that vegetation is formally protected, is described by threatened environment categories. These can be monitored to understand the effects of land cover change on indigenous biodiversity.

This dataset relates to the "Indigenous cover and protection in land environments" measure on the Environmental Indicators, Te taiao Aotearoa website.

The data identifies five classes of land in New Zealand at risk of erosion:

  1. high landslide risk – delivery to stream
  2. high landslide risk – non-delivery to steam
  3. moderate earthflow risk
  4. severe earthflow risk
  5. gully risk

Landslide erosion is the shallow (approximately 1m) and sudden failure of soil slopes during storm rainfall. Earthflow erosion is the slow downward movement (approximately 1m/year) of wet soil slopes towards waterways. Gully erosion is massive soil erosion that begins at gully heads and expands up hillsides over decadal time scales.

Erosion can have negative consequences on land productivity, water quality (via increased sedimentation and turbidity), the natural form of the land, and infrastructure.

New Zealand experiences high rates of soil erosion. In the North Island, this is mostly due to the historical clearance of forest for agriculture (see also Estimated long-term soil erosion). In contrast, erosion in the South Island is mostly due to natural processes, primarily high rainfall and steep mountain slopes.

It is important to identify areas of land at risk of severe erosion to inform land-use decisions and help prioritise regional soil conservation work.

Mast-seeding events occur when plant species (eg New Zealand flax or trees such as the beech species) produce very large amounts of seed, usually every 4–6 years. These events are vital for the survival of some indigenous bird species. Unfortunately, the increase in food supply also prompts a dramatic increase in the numbers of mice, rats, and stoats (a population irruption). In the years after mast-seeding events, rats and stoats target birds and other prey.

New Zealand’s indigenous and exotic forests absorb and store carbon from the atmosphere through photosynthesis. As forests grow, the carbon stored in them increases. These carbon stocks help offset greenhouse gas emissions from sources such as agriculture, energy production, and transport.

Column headings:
type = vegetation type of forest
vol_tC = volume of carbon in tonnes
