New Zealand has unique indigenous plants and animals that are our national taonga (treasures). Because most are endemic (found nowhere else in the world) New Zealand makes an important contribution to global biodiversity. Biodiversity is important for ecosystem processes, te ao Māori including mahinga kai (customary food gathering), and culture and recreation.

The conservation status of our biodiversity represents their risk of extinction. This data covers the conservation status, and most-recent change in status, of native and resident taxa for which we had sufficient information on abundance and distribution. This includes bats, birds, earthworms, lichens, plants, reptiles and frogs, snails, spiders, and insects.

We also include the number of species that have had a genuine change in conservation status between assessment periods.Where conservation status changed, this measure also looked at the NCTCS listings done in 2012 for birds (Robertson et al, 2017); 2012 for reptiles (Hitchmough et al, 2015); and 2010 for Orthoptera (Trewick et al, 2012). A change in a species’ conservation status reflects a change in its risk of extinction.

Fresh water in New Zealand is highly valued for recreational activities, including fishing. Freshwater angling (primarily for introduced ‘sports fish’ such as brown trout, rainbow trout, and chinook salmon) is a popular leisure activity. Fish licences issued by Fish & Game New Zealand provide an indication of recreational fishing activity at freshwater locations around the country.

This dataset relates to the "Participation in recreational fishing" measure on the Environmental Indicators, Te taiao Aotearoa website.

One third of our land area is held as public conservation land and managed by the Department of Conservation (DOC) to protect natural and cultural heritage, retain areas of wilderness and enable recreation opportunities. Although the use of public conservation land makes an important socio-economic contribution at the local, regional and national level, increasing human activities on our protected areas can put pressure on these environments and degrade their cultural and aesthetic value. These activities can range from recreational users on our Great Walks to commercial activities such as guiding, grazing, or building structures.

This measure reports on the capacity and number of booked bed nights in huts and campsites on nine Great Walks operating in national parks, by walk, hut/campsite and month.

The Interdecadal Pacific Oscillation (IPO) is a long-term oscillation of sea-surface temperatures in the Pacific Ocean that can last from 20 to 30 years. Its positive and negative phases affect the strength and frequency of El Niño and La Niña. In New Zealand, the positive phase is linked to stronger west to southwest winds and more rain in the west. This trend is reversed during the negative phase.

Our fish stocks are affected by commercial, customary, and recreational fishing, and environmental pressures (eg ocean temperature, acidity, and productivity). The Ministry for Primary Industries uses three performance measures to assess influences on fish stocks: a soft limit (below which a rebuilding plan is required), a hard limit (below which closing a fishery should be considered), and an overfishing threshold (where the rate of extraction is higher than the rate of replenishment).

Livestock numbers reflect changes in the number of farmed beef and dairy cattle, deer, and sheep across New Zealand. Livestock farming is a widespread land use in this country. It is important to monitor this use because it can affect the indigenous biodiversity, soil health, and water quality.

Column headings:
numbers = numbers of animals

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

When nutrients accumulate in lakes (referred to as ‘nutrient enrichment’) above certain levels, they can make the lakes murky and green with algae, and lower oxygen levels. Lakes with extremely poor water quality are rarely suitable for recreation and provide poor habitats for aquatic species.

Percentile calculations for the following parameters are provided:
Trophic Level Index 3 (TLI)
Chlorophyll-a (CHLA)
Bottom-water dissolved oxygen (DObottom)
Ammoniacal nitrogen (NH4N)

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)

Growing degree days (GDD) measures the amount of warmth available for plant and insect growth and can be used to predict when flowers will bloom and crops and insects will mature. GDD counts the total number of degrees Celsius each day is above a threshold temperature. In this report we used 10 degrees Celsius. Increased GDD means that plants and insects reach maturity faster, provided that other conditions necessary for growth are favourable, such as sufficient moisture and nutrients. As a measure of temperature, GDD experiences short-term changes in response to climate variations, such as El Niño, and in the longer-term is affected by our warming climate.
This dataset gives the number of GDD per month and calendar year for all 30 sites.

New Zealand is a water-rich country. Water is found in a network of waterways and lakes, as ground water, in glaciers, and in the soil and plants. Changes in temperature and precipitation patterns affect our water stocks, for example leading to low flows or floods. Water physical stocks show how climate changes can impact on our environment, its ecosystems, and ultimately our lifestyles.
