Information stocktakes of fifty-five environmental attributes across air, soil, terrestrial, freshwater, estuaries and coastal waters domains

Characteristics of our land, water, soil and air, known as attributes, help us understand how our environment is changing and inform how we maintain human health and ecological integrity at acceptable levels.

Characteristics of our land, water, soil and air, known as attributes, help us understand how our environment is changing and inform how we maintain human health and ecological integrity at acceptable levels.

The Ministry for the Environment commissioned 43 researchers from NIWA, Manaaki Whenua Landcare Research, Cawthron Institute and Environet Limited to bring together existing information on 55 environmental attributes.

These attributes are in air, terrestrial, soil, freshwater, and estuaries and coastal waters domains. They cover issues as diverse as wetland extent and light pollution. The information can be accessed either as a full report or attribute by attribute (below).

Air

5.1 Light pollution
5.2 Nitrogen dioxide in air
5.3 Sulphur dioxide in air
5.4 Carbon monoxide in air
5.5 Ozone in air
5.6 Black carbon in air
5.7 Benzo(a)pyrene in air
5.8 Arsenic in air
5.9 Benzene in air
5.10 Lead in air
5.11 Cadmium in air

Terrestrial

6.1 Wetland extent
6.2 Dune extent
6.3 Lowland forest extent
6.4 Wetland condition index
6.5 Dune condition index
6.6 Indigenous plant dominance
6.7 Canopy die back extent
6.8 Landscape connectivity

Soil

7.1 Peatland/peat soils subsidence control
7.2 Soil bacteria composition
7.3 Soil nitrogen and phosphorus
7.4 Soil carbon
7.5 Landslide susceptibility mitigation
7.6 Gully erosion
7.7 Surface erosion/runoff control
7.8 Riparian protection/streambank erosion control
7.9 Soil compaction
