This indicator will show the benefits New Zealanders get from the regulation or control of our natural ecosystems. This includes ecosystems in forests, freshwater and marine environments, grasslands, and agricultural environments.
For example, benefits can result from regulating:
- climate (eg trees provide shade, and forests influence rainfall and water retention, and sequester carbon)
- populations (eg predators and parasites help control potential prey populations)
- water (eg wetlands filter effluents and treat waste, helping purify water)
- air (eg trees and other plants purify the air by removing pollutants from the atmosphere)
- some human diseases (eg parasite activities can control some disease vectors).
