Indicator Topics

The UNI is structured around 30 indicator topics nested across six themes. The indicator topics allow for the analysis and monitoring of different aspects of urban nature. Thanks to the flexible nature of the UNI, and given potential capacity constraints, cities are recommended to implement at least one indicator topic per theme.

  • Animal Species

    Measure citywide animal species diversity.

  • Plant Species

    Measure of citywide plant species diversity.

  • Functional Diversity

    Assess ecosystem health and resilience by measuring functional diversity.

  • Microbiota and fungi

    Measure the health of soils, fungi and microbiotic systems in aquatic and terrestrial areas.

  • Endemic Species

    Assess the richness and conservation status of endemic species (where endemicity may be regional or local).
