Different land uses put pressure on the land environment and can result in changes to soil health. Healthy soil supports the productivity of agriculture and forestry, and filters water to help prevent waterways becoming contaminated. Soils are considered healthy if they fall within the target ranges for the indicators of acidity, fertility, organic reserves, and physical status.

This dataset relates to the "Soil health and land use" measure on the Environmental Indicators, Te taiao Aotearoa website.

Some areas of New Zealand’s North Island are classified as highly erodible land. They have steep slopes and are at high risk of mass soil movement due to the absence of woody vegetation cover with deep roots to hold the soil in place. This can lead to soil erosion. It is important to identify areas of land at risk of severe erosion to inform land use decisions and help prioritise soil conservation work.

This dataset relates to the "Estimated highly erodible land in the North Island" measure on the Environmental Indicators, Te taiao Aotearoa website.

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

This dataset relates to the "Estimated forest carbon stocks" measure on the Environmental Indicators, Te taiao Aotearoa website.

Data on the economic performance of the agriculture industry describes agriculture’s contribution to the New Zealand economy. It provides supporting information for the land, atmosphere and climate, and freshwater domains.

Soil erosion reduces the productive capacity of land. Sediment entering waterways affects water quality, storage capacity, and biodiversity. Soil erosion in the North Island is primarily due to the historical clearance of forest on steep slopes for pastoral agriculture. South Island soil erosion is primarily due to high rainfall and steep mountainous terrain.

Column headings:
vol_tkm2yr = volume of soil lost per year measured in tonnes per square kilometer

This dataset relates to the "Estimated long-term soil erosion" measure on the Environmental Indicators, Te taiao Aotearoa website.

Data on the economic performance of the agriculture industry describes agriculture’s contribution to the New Zealand economy. It provides supporting information for the land, atmosphere and climate, and freshwater domains.

Land cover describes the extent of vegetation, water bodies, built environment, and bare natural surfaces (eg gravel and rock) across New Zealand. Measuring the composition and changes in land cover can help us better understand the pressures that different land uses are placing on the biodiversity and functioning of ecosystems.

Column headings:
area_ha = area of land cover measured in hectares

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

Rare ecosystems are ecosystems that either naturally cover very small areas or have very little of their original extent remaining. The extent to which they are threatened with extinction informs their conservation priority.

Column headings:
no_ecosys = number of rare ecosystems

This dataset relates to the "Rare ecosystems" 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.
