Pollinators from a range of taxa benefit nearly 80% of wild plants in Europe (Ollerton et al., 2011), including crops. Pollinators contribution to crop production and farmers income have already been demonstrated (Gallai et al., 2009). The current pollinator decline had brought a deficit of pollination (Garibaldi et al., 2011) for many crops with some impact on human health (Chaplin-Kramer et al., 2014) and evaluated mortality of ½ million of people in the world (Smith et al., 2022).
Restoring pollinators, their habitats and landscape connectivity is thus a major issue for biodiversity conservation, agriculture sustainability and human health. Restoration measures, other than flowering strips on arable land, are rarely studied with respect to wild bees and other pollinator populations, their diversity and pollination services.
To evaluate the success of grassland restoration using functional approaches at local and landscape scale (behaviour and connectivity)
To estimate the effect of grassland restoration on wild plant and crops
Methods used to conduct this project range from field work: insect trapping, botanical records and behavioural records; as well as spatial modelling (using already running models).
