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_t_yr = volume of sediment entering wayerways each year measured in tonnes

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

DATA SOURCE: Department of Conservation (DOC)

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

Dataset used to develop the "Extinction threat to indigenous land species" indicator [available at www.stats.govt.nz/indicators/extinction-threat-to-...]

​

We report on the extinction threat to indigenous, resident, living land species that have been assessed by expert panels under the New Zealand Threat Classification System (NZTCS). They include bats, frogs, reptiles, terrestrial invertebrates, vascular plants, non-vascular plants (mosses, hornworts, and liverworts), lichens and terrestrial birds (which exclude seabirds and shorebirds, which are reported under extinction threat of indigenous marine species).

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.

Farm numbers describes the number of large commercial properties (registered for goods and services tax) that farm crops and/or livestock. It is important to measure the number of large farms involved in these agricultural activities because their extent determines their impacts on soil health and water quality.

Column headings:
num_farms = number of farms

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

Dataset used to develop the "Farm numbers and size" indicator [available at www.stats.govt.nz/indicators/farm-numbers-and-size]

​

We present the number and area of farms in New Zealand and by region from 2002 to 2019.

Farm size describes the area of large commercial properties (registered for goods and services tax) that farm crops and/or livestock. It is important to measure the extent of these agricultural activities because their size influences the extent of their impacts on soil health and water quality.

Column headings:
area_ha = total area of farming activity measured in hectares

This dataset relates to the "Farm size" 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 "Fertilisers phosphorus and nitrogen applied" indicator [available at statisticsnz.shinyapps.io/farm_fertiliser_ap...]

​

This indicator measures the amount of nitrogen and phosphorus-based fertiliser (Urea, diammonium phosphate, superphosphate and ammonium sulphate) applied to agricultural land from 2002 to 2019 by region and dominant farm type.

Dataset used to develop the "Far fertiliser applied" indicator [available at statisticsnz.shinyapps.io/farm_fertiliser_ap...]

​

This indicator reports industry estimates of nitrogen and phosphorus (as elements) sold in fertiliser products nationally from 1991 to 2019.
