New Zealand's Environment Reporting Series: The Ministry for the Environment and Statistics New Zealand
This indicator measures the physical habitat condition of New Zealand waterways. We report on 369 sites across six North Island regions and 90 sites in one South Island region (Southland), identifying the overall state of stream habitat at each site based on at least three years of data between 2013/14 and 2018/19. Ten physical habitat components are measured during the assessment, including bank erosion and the diversity and abundance of fish cover (Clapcott et al, 2019). 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.
