group, with half on butterflies (n = 10) and the others on unspecified bees ( n = 7), bumblebees (n = 3) and hoverflies ( n = 2). Figure 9 shows the number of articles for specific management options. Field margins (n = 17), Meadows ( n = 10) including Ecological Compensation Area Meadows (specific to Switzerland n = 9) and hedgerows ( n = 11) were the most common. It may be that more evidence is needed to test the efficacy of management options. Some options are for specific organisms eg. Lapwing option, whereas others are not. Table 7 gives the group studied for each option.
