The main objective of the third activity (A3) is to quantify biodiversity and ecosystem services provided by each EFA type and by the agricultural dominated matrix. We will conducted several field surveys to obtain data from vegetation, insects, ants, birds, bats and dummies caterpillars. Biological data will be then converted in several biodiversity measures (Shannon diversity indices; species abundance, species richness, functional metrics) and Ecosystems Services indicators (pollination and predation capacity). All indicators will be expressed in relative variables, therefore comparable across biological groups, EFAs types, and between EFAs and the agricultural matrix. The field team will be sampling at the same time to ensure spatial and temporal similarity of data.
We will be also assess the habitat quality of each EFA type, using a field protocol, the Biodiversity Potential Index (BPI) – adapted from the French IBP. The adapted BPI will be assessed in sampling plots, to register indicators of habitat quality of EFAs, covering four groups of indicators (vegetation structure, vegetation habitats, associated habitats and EFAs management).
