Area under agri-environmental management per package group: The subsidy packages are bundled in groups of packages for nest protection, heavy meadow bird management, arable land, botanic grassland and landscape. The area under nest protection management packages is the biggest, but between 2006 and 2016 it decreased by more than half. The area of arable land under agri-environmental management has increased, while the area under management for botanic (flower-rich) grassland has declined.
