Predicted average Macroinvertebrate Community Index (MCI) score, 2007–2011
Ministry for the Environment"Macroinvertebrates are small animals without backbones that live on and under submerged logs, rocks, and aquatic plants in the stream bed during some period of their life cycle. They play a central role in stream ecosystems by feeding on periphyton (algae or slime), macrophytes (aquatic plants), dead leaves and wood, or on each other. High...Created 2 February 2020 • Updated 3 March 2025 -
Distribution of feral goats 2002–2014
Ministry for the Environment"The pressure from animal and plant pests is one of the biggest threats to biodiversity in the land environment. Pest predators (such as stoats and possums) eat eggs, birds, lizards, insects, and snails. Other animal pests (such as deer and goats) damage and kill trees and other plants and can compete with indigenous animals for the plants’ fruit and...Created 2 February 2020 • Updated 3 March 2025 -
Benthic protection areas (2016 report)
Ministry for the EnvironmentNew Zealand’s four million km2 marine environment is diverse, with a range of coastal habitats and offshore seabed environments. There are also many marine species unique to New Zealand. Marine protected areas conserve or manage some of these unique habitats and species, while a range of other tools also provide marine protection. We report on the area...Created 2 February 2020 • Updated 3 March 2025 -

Freshwater pests: Margaret River Marron
Ministry for the Environment"Freshwater plant and animal pests can have significant negative impacts on ecosystem health by reducing indigenous biodiversity through predation and competition, and destabilising aquatic habitats. Freshwater plant pests can cause economic losses through blocking water intakes for hydroelectricity generation, impeded drainage or irrigation. In addition,...Created 2 February 2020 • Updated 3 March 2025 -

Mortality of indigenous tree sp Halls tōtara 2002–2014
Ministry for the Environment"The rates of death (mortality) of indigenous tree species vary across New Zealand. Changes in the state of the environment (such as from browsing pests, large-scale weather events, or climate change) may change the rates of mortality of particular tree species. This in turn may alter forest processes. Repeated surveys of the distribution of mortality...Created 2 February 2020 • Updated 3 March 2025 -
Water clarity, 1989–2013
Ministry for the Environment"Water clarity is a measure of underwater visibility in rivers and streams and can vary due to differences in land use, climate, elevation, and geology. Water clarity can be reduced by the presence of fine particles like silt, mud or organic material in the water. This affects the habitat and feeding of aquatic life like fish and aquatic birds. Water...Created 2 February 2020 • Updated 3 March 2025 -

NZ Coastal Hydrosystems
Ministry for the EnvironmentCoastal hydrosystems describe coastal features that span a gradient from near coast freshwater lakes/wetlands (lacustrine/palustrine environments) to marine. The term 'coastal hydrosystem' avoids the common error of referring to all such features as estuaries, mislabelling the numerous types that are non-estuarine and have different behavioural...Created 2 February 2020 • Updated 3 March 2025 -
