5.1 Bat, Bird, and Insect Diversity

Purpose of indicator

Relevant for the post-2020 Global Biodiversity Framework Target 10 on ‘Proportion of agricultural area under productive and sustainable agriculture’. In addition to evaluation of on farm crop and Livestock diversity, this metric will summarise species level diversity of trees, birds and insects within the farm landscape used by farmers. It will combine field transects and use state of the art acoustic monitoring and school-based citizen science monitoring to evaluate, bird, insect and bat diversity across the ALLs.

Key Metadata

Metadata Item	Description
Indicator Name	Bat, bird and insect diversity
Theme	Biodiversity
SDGs Targeted	Post-2020 Global Biodiversity Framework Target 10
Data Source	Field survey, field based Passive Acoustic Monitoring (PAM), and citizen science
Measurement	Bird species diversity and guilds, insect diversity, based on acoustic profiles, and bat diversity, based on automatic monitoring.
Measurement Units	Bird, Bat and Insect diversity, species number.

Guidance on Measurement

This indicator can be calculated by collecting data on the:

• Total number of bird species, and their guilds (forest species, generalist, rarity).
• Total number of detected insect species or complexity of insect acoustic profile.

These data can be collected as part of a field survey, and using base stations set up in each ALL. To verify the data, and help to obtain area estimates, users can work with the SoundLab University of Wisconsin or other established analysts.

Guidance on Data Entry and Reporting

Be sure to use the same area units and monitoring acoustic stations for all sites and species, so that diversity indices can be calculated. Bird, bat and insect species names should be stored in the local language and also using their scientific and English names to enable comparisons across sites.
